c - Creating a struct of callbacks in LuaJIT FFI -

so first load in dll need

local ffi = require("ffi") local thedll = ffi.load("thisdll")

in ffi cdef have struct

ffi.cdef [[ typedef struct { /* * begin_proj callback */ bool (__cdecl *begin_proj)(char *proj); /* * save_proj_state */ bool (__cdecl *save_proj_state)(unsigned char **buffer, int *len); } structcallbacks;

i have function in cdef

__declspec(dllexport) int __cdecl start_session(structcallbacks *cb);

now phone call function

print(thedll.start_session(mycallbacks))

the question how can pass structs function needs (how create mycallbacks struct of callbacks lua functions)?

just create struct , assign fields lua functions, other value.

local callbacks = ffi.new("structcallbacks") callbacks.begin_proj = function(proj) homecoming false end callbacks.save_proj_state = function(buffer, len) homecoming true end

see ffi callback docs more in-depth info on callbacks.

java - How to set a timezone with org.joda.time? -

i want parse string datetime object:

datetimeformatter fmt = datetimeformat.forpattern("m/d/yyyy hh:mm"); datetime dt = fmt.parsedatetime(stringdate + " " + stringtime).withzone(datetimezone.forid("europe/dublin"));

if introduce time 06/22/2014 10:43 get

06/22/2014 8:43 +0100,

but want get

06/22/2014 10:43 +0100

how can this?

you should apply timezone formatter, not datetime. otherwise, date have been parsed in local timezone, , you're simply transposing desired timezone.

datetimeformatter fmt = datetimeformat.forpattern("m/d/yyyy hh:mm") .withzone(datetimezone.forid("europe/dublin")); datetime dt = fmt.parsedatetime("06/22/2014 10:43");

function getvariablefromid(id) { switch (id) { case "gta1": homecoming gta1; case "gta2": homecoming gta2; case "gta3": homecoming gta3; ... case "gtj0": homecoming gtj0; } }

so have switch statement in code takes #id of div tag using .attr , associates javascript variable. each numeric code represents 1 square on chessboard-like grid. there 100 squares. there easier or more compact method performing calculation this, or simplest way?

use array instead of 100 variable , hundred conditions in switch. array array of strings/numbers or objects. declare array number of elements want , number id utilize index of array.

arrgta = ["somevalue1", "somevalue2"]; //could array of strings/numbers or objects. function getvariablefromid(id) { idx = parseint(id.replace("gta", "")); homecoming arrgta[idx-1]; }

ios - UISearchDisplayController UISearchBar Animation in a UIScrollView under UIPageControl -

it's tough bug squash, objc-fu beginner , confidence crashing longer pretty bug...

the app required have view (let's phone call mainview) uipagecontrol , uiscrollview in order have 2 views scrollable horizontally. hence have implemented adding:

// added on viewdidload... [self addchildviewcontroller:[self.storyboard instantiateviewcontrollerwithidentifier:@"vc1"]]; [self addchildviewcontroller:[self.storyboard instantiateviewcontrollerwithidentifier:@"vc2"]]; // farther processing of kid view controllers... self.scrollview.pagingenabled = yes; (nsuinteger = 0; < [self.childviewcontrollers count]; i++) { uiviewcontroller *controller = [self.childviewcontrollers objectatindex:page]; cgrect frame = self.scrollview.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; controller.view.frame = frame; [self.scrollview addsubview:controller.view]; } // expanding scroll view's content size scrolling... self.scrollview.contentsize = cgsizemake( scrollview.frame.size.width * [self.childviewcontrollers count], scrollview.frame.size.height);

note mainview equipped uisearchdisplaycontroller having uisearchbar hidden offscreen. (not sure if info vital.)

the problem in sec kid view controller identifier vc2 equipped uisearchdisplaycontroller having uisearchbar, , when search bar dismisses on end searching, animation how create vc2's uisearchbar reposition in cgrect(0, 0, 320, 40) of mainview instead of vc2. hence vc2's uisearchbar "warped" vc1.

first effort solve containing each kid view controller in view hoping cgrect(0, 0, 320, 40) of vc2's uisearchbar remain in vc2, no avail:

for (nsuinteger = 0; < [self.childviewcontrollers count]; i++) { uiviewcontroller *controller = [self.childviewcontrollers objectatindex:page]; cgrect frame = self.scrollview.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; //controller.view.frame = frame; uiview *container = [[uiview alloc] initwithframe:frame]; [container addsubview:controller.view]; [self.scrollview addsubview:container]; }

somehow guessing when vc2's uisearchdisplaycontroller animates it's uisearchbar frame uses 1 of self.uiscrollview not sure.

could please shed lite on bug , fire death please? it's in ios7

main view ------------------- | vc1 | vc2 ------------------------------------- | |_________________| <- search bar (this 'warped' vc1 @ same | | | position on end editing) | | | | | | | | | | | | | | | | | | | | | | | | -------------------------------------

found solution, weird, works, got thought searchbar disappears headerview in ios 7 after noticing memory address of uisearchbar's superview changed on end search.

the next code snippet added of delegated methods possible, namely viewwillappear, searchdisplaycontrollerwillendsearch:, searchdisplaycontrollerdidendsearch::

if (self.searchdisplaycontroller.searchbar.superview != self.searchdisplaycontroller.searchcontentscontroller.view) { [self.searchdisplaycontroller.searchbar removefromsuperview]; [self.searchdisplaycontroller.searchcontentscontroller.view addsubview:self.searchdisplaycontroller.searchbar]; }

will take reply still should there wrong share. give thanks much.

css3 - CSS specificity for elements with more than one class -

css3 - CSS specificity for elements with more than one class -

i having issue unable level of specificity need create code work. have <ul> want create backgrounds of <li>'s alter when hovered on fancy little slide-in animation.

i managed working pretty using linear-gradient transition on :hover. decided wanted have different list items have different background colors each other, added 3 classes: .red, .blue, , .gold, , figured create .level1 class have required properties other linear gradient itself—namely, background-size: 200% 100%, background-position:right bottom, , transition:all 1s ease, , specify linear gradient , color each individual color class. know pretty intangible, post code below.

here hoping have (or it):

body .push [class^="level1"] { background-size: 200% 100%; background-position:right bottom; transition:all 1s ease; } body .push [class^="level1"]:hover { background-position:left bottom; } body .push .level1.blue { background: linear-gradient(to right, #282e59 50%, rgba(0,0,0,0) 50%); } body .push .level1.red { background: linear-gradient(to right, #94272a 50%, rgba(0,0,0,0) 50%); } body .push .level1.gold { background: linear-gradient(to right, #e5d037 50%, rgba(0,0,0,0) 50%); }

but doesn't work. values in first class take effect, have rid of first 1 body .push [class^="level1"] { ... } , set info in 3 color-specific ones,

body .push .level1.blue { background: linear-gradient(to right, #282e59 50%, rgba(0,0,0,0) 50%); background-size: 200% 100%; background-position:right bottom; transition:all 1s ease; } body .push .level1.red { background: linear-gradient(to right, #94272a 50%, rgba(0,0,0,0) 50%); background-size: 200% 100%; background-position:right bottom; transition:all 1s ease; } body .push .level1.gold { background: linear-gradient(to right, #e5d037 50%, rgba(0,0,0,0) 50%); background-size: 200% 100%; background-position:right bottom; transition:all 1s ease; }

is there way consolidate information?

it seems problem not specificity, shorthand background: declaration overwriting position & size values in original declaration. seek changing background: background-image: in overwrites:

body .push .level1.blue { background-image: linear-gradient(to right, #282e59 50%, rgba(0,0,0,0) 50%); } body .push .level1.red { background-image: linear-gradient(to right, #94272a 50%, rgba(0,0,0,0) 50%); } body .push .level1.gold { background-image: linear-gradient(to right, #e5d037 50%, rgba(0,0,0,0) 50%); }

ruby - A hash using lambdas without relying on conditionals or enumerators -

if have list of accepted aliases , root names basic colors:

coloraliases = { ["red", "crimson", "auburn", "rose", "maroon", "burgundy"] => "red", ["blue", "teal", "aqua", "azure", "cobalt"] => "blue", ["green", "emerald", "absinthe", "avocado", "lime"] => "green", ["yellow", "banana", "lemon", "gold", "citrine"] => "yellow" }

i couldn't this:

coloraliases["crimson"] #=> "red"

i'm trying coax behavior so:

basecolor = lambda |str| x = nil coloraliases.each |keys, value| if keys.include?(str) x = value break end end# of coloraliases hash x end

which should work expected.

am wondering if there more elegant ways this, ways not involving conditional blocks or enumerators. ternary operators ok or improve because they're compact still not preferable because they're conditionals.

your hash design wrong. not using in way hash supposed used. should be:

coloraliases = { "red" => "red", "crimson" => "red", "auburn" => "red", "rose" => "red", "maroon" => "red", "burgundy" => "red", "blue" => "blue", "teal" => "blue", "aqua" => "blue", "azure" => "blue", "cobalt" => "blue", ... }

and then, get:

coloraliases["crimson"] # => "red"

[update]

i've tried it:

int normaltextcolor = color.argb( 0, 0, 0, 0); int pressedfiltercolor = color.argb(225, 238, 11, 83); bitmap bitmap = bitmap.createbitmap(1, 1, bitmap.config.argb_8888); //make 1-pixel bitmap canvas canvas = new canvas(bitmap); canvas.drawcolor(normaltextcolor); //color want apply filter canvas.drawcolor(pressedfiltercolor, porterduff.mode.lighten); //apply filter int pressedtextcolor = bitmap.getpixel(0, 0); textview.settextcolor(pressedtextcolor);

but still not working.

as raybaybay said no simple way in android. going have work layers. if familiar photoshop or gimp, how layers are, if not take here http://docs.gimp.org/en/gimp-image-combining.html#gimp-concepts-layers. key here know how combine layers. start testing screen , multiply modes http://developer.android.com/reference/android/graphics/porterduff.mode.html. javadoc on porterduff modes useless, article (jump straight "transfer" section) should help http://www.xenomachina.com/2011/05/androids-2d-canvas-rendering-pipeline.html understand going on.

now, code see familiar android samples. should check graphics/xfermodes demo, on "apidemos" sample. can install straight eclipse: new > other > android sample project. demo shows porterduff modes there , how utilize them. hope helps.

i'm new jpa , hibernate , have problem optimistic locking. have class wich hase @version annotated field. when update entity represented class, version counter not increase. here code: class:

@entity @table (name = "studenten") public class pupil implements serializable{ private static final long serialversionuid = 705252921575133272l; @version private int version; private int matrnr; private string name; private int semester; public pupil (){ } public pupil (int matrnr, string name){ this.matrnr = matrnr; this.name = name; } public pupil (int matrnr, string name, int semester){ this(matrnr, name); this.semester = semester; }

and here main method:

public static void main(string[] args) { entitymanagerfactory emf = persistence.createentitymanagerfactory("veda_vortrag"); entitymanager em = emf.createentitymanager(); entitytransaction tx = em.gettransaction(); try{ tx.begin(); pupil s = em.find(student.class, 195948); s.setsemester(1); em.persist(s); tx.commit(); }catch(exception e){ if(tx != null && tx.isactive()){ tx.rollback(); system.out.println("error in transaction. rollback!"); } } finally{ em.close(); emf.close(); } }

and here console says:

hibernate: select student0_.matrnr matrnr0_0_, student0_.name name0_0_, student0_.semester semester0_0_, student0_.version version0_0_ studenten student0_ student0_.matrnr=? hibernate: update studenten set name=?, semester=?, version=? matrnr=?

can tell me what's wrong?

edit: ok, have tried something. i've set locking lockmodetype.optimistic_force_increment , got error-message:

error: hhh000099: assertion failure occured (this may indicate bug in hibernate, more due unsafe utilize of session): org.hibernate.assertionfailure: cannot forcefulness version increment on non-versioned entity jun 20, 2014 9:00:52 org.hibernate.assertionfailure <init>

so seems clear have non-versioned entity. why? have @version annotation in class.

edit: begin think problem in persistence.xml. here is:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> <persistence-unit name="veda_vortrag"> <provider>org.hibernate.ejb.hibernatepersistence</provider> <properties> <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/uni"/> <property name="javax.persistence.jdbc.user" value="*******"/> <property name="javax.persistence.jdbc.password" value="******"/> <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.driver"/> <property name="hibernate.dialect" value="org.hibernate.dialect.mysqldialect"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> </properties> </persistence-unit>

is there wrong?

the entitymanager.persist() method used new entities have never been persisted before.

because fetching entity don't need phone call persist or merge anyway. dirty checking update on behalf.

the commit trigger flush anyway should see update.

make sure utilize javax.persistence.version annotation , not other bundle (spring info or similar).

you see junk because cf_text ansi. request ansi text, os converts clipboard contents ansi, , set in unicode string. utilize cf_unicodetext unicode applications.

xcode - Range of doubles in Swift -

xcode - Range of doubles in Swift -

i writing swift application , parts of require making sure user inputs add together specified value.

a simplified example:

through programme interaction, user has specified totalvalue = 67 , turns = 2. means in 2 inputs, user have provide 2 values add together 67.

so lets on turn 1 user enters 32, , on turn 2 enters 35, valid because 32 + 35 = 67.

this works fine, moment verge more 1 decimal place, programme cannot add together numbers correctly. example, if totalvalue = 67 , on turn 1 user enters 66.95 , on turn 2 enters .05 programme homecoming error despite fact 66.95 + .05 = 67. problem not happen 1 decimal place or less (something turn 1 = 55.5 , turn 2 = 11.5 works fine), 2 decimal spots , beyond. storing values doubles. in advance

some illustration code:

var totalweights = 67 var input = double(mytextfield.text.bridgetoobjectivec().doublevalue) /*each turn button click*/ /*for turn 1*/ if inputvalid == true && turn == 1 && input < totalweights { myarray[0] = input } else { //show error string } /*for turn 2*/ if inputvalid == true && turn == 2 && input == (totalweights - myarray[0]) { myarray[1] = input } else { //show error string }

if want exact values floating point float/double types not work, ever approximations of exact numbers. using nsdecimalnumber class within swift, i'm not sure bridging should simple.

From trailing slash to query (PHP/.htaccess) -

From trailing slash to query (PHP/.htaccess) -

i maintain links in address bar short , clean possible, example:

http://example.com/th1ng

if in database there row 'th1ng' username, above link should work like

http://example.com/user.php?name=th1ng

while still showing first, clean link in address bar.

if user doesn't exist, shows/redirects 404 page.

also, there other files , directories need access via trailing slash too. , possible there query on top well, like

http://example.com/th1ng?img=13805

which should deed like

http://example.com/user.php?name=th1ng?img=13805

i got of php stuff, including database check , redirecting 404 in case user doesn't exist.

but.. proper way around showing clean link in address bar? other files , directories on server still beingness accessible well. can assume .htaccess needs used don't see how exactly.

thanks help!

you need utilize mod_rewrite that. placed in .htaccess.

r - Divide 3D space into smaller cubes -

i have set of points in 3d. want split entire volume occupied points 128x128x128 number of cubes. , want count number of points in each cube. can suggest how in r?

i have tried rgb , scatterplot3d packages did not find solution there. also, need color these cubes in accordance numbers. please suggest how go it.

although not influence solution, info not symmetrically spread in directions. split quantity: max(x,y,z) 128 border length of each cube.

thank you.

if sure want do, here's attempt.

dat <- as.data.frame(replicate(3, runif(10000))) # toy info n <- 3 # set 128, number of cubes in each direction cut_dat <- lapply(dat, cut, breaks = seq(0, 1, l = n + 1)) # break cubes do.call(table, cut_dat) # cross tabulate count #, , v3 = (0,0.333] # # v2 #v1 (0,0.333] (0.333,0.667] (0.667,1] # (0,0.333] 383 361 379 # (0.333,0.667] 362 382 371 # (0.667,1] 389 358 370 # #, , v3 = (0.333,0.667] # # v2 #v1 (0,0.333] (0.333,0.667] (0.667,1] # (0,0.333] 345 383 372 # (0.333,0.667] 374 388 381 # (0.667,1] 383 368 373 # #, , v3 = (0.667,1] # # v2 #v1 (0,0.333] (0.333,0.667] (0.667,1] # (0,0.333] 342 355 360 # (0.333,0.667] 386 386 374 # (0.667,1] 346 372 357

so 3d array counts. have reduced number of cubes 3 in each direction display concept.

edit: gavin kelly's suggestion can done here

table(cut_dat[[1]]:cut_dat[[2]]:cut_dat[[3]])

to info representation.

or more human readable:

tab2 <- expand.grid(lapply(cut_dat, levels)) tab2$freq <- table(cut_dat[[1]]:cut_dat[[2]]:cut_dat[[3]]) head(tab, n = 4) # v1 v2 v3 freq #1 (0,0.333] (0,0.333] (0,0.333] 374 #2 (0.333,0.667] (0,0.333] (0,0.333] 379 #3 (0.667,1] (0,0.333] (0,0.333] 384 #4 (0,0.333] (0.333,0.667] (0,0.333] 377

f# - Why do I see the Program+ prefix when printfn tries to print an object? -

f# - Why do I see the Program+ prefix when printfn tries to print an object? -

i have object of class created, printing object %a format specifier, see typename program+myclass instead of myclass ? why that?

someone might programme namespace, if how come not able next ?

let o = program+myclass()

here total code

open scheme type myclass() = fellow member val x = 3 get,set [<entrypoint>] allow main argv = allow o = myclass() o |> printfn "here myclass object %a" console.readkey() 0 // homecoming integer exit code

as john correctly explains, part before + in program+myclass there because code compiled program module. f# modules compiled nested classes , myclass nested class within program (which static class) , + comes standard .net naming of nested classes.

you can avoid putting class in namespace (but you'll still need have main function in module):

namespace myprogram open scheme type myclass() = fellow member val x = 3 get,set module main = [<entrypoint>] allow main argv = allow o = myclass() o |> printfn "here myclass object %a" console.readkey() 0 // homecoming integer exit code

now, myclass straight in namespace (not nested class) , print without program+ prefix.

jsfiddle

to stop , destroy scroller need "undo" li-scroller adds can utilize followiing jquery:

$("ul#ticker01") .clearqueue().stop() //stops animation .unwrap() //removes mask div .unwrap() //removes tickercontainer div .unbind() //unbinds events attached (like hover) .removeclass('newsticker') //removes class .removeattr('style'); //removes height style

c - Query on handling TAB character? -

c - Query on handling TAB character? -

in ascii characterset world, below 3 whitespace characters have number.

space(32) linefeed(10) carriagereturn(13)

so, easy write programme read or write such whitespace characters in standard way using programming language(like c) in portable way, using next notations,

linefeed - '\n' carriage homecoming - '\r' space - ' '

i learnt tab collection of 4 or 8 space characters.

my question:

how understand meaning of '\t' character in programming language(like c)? when there no standard definition of tab in characterset world?

in ascii, horizontal tab code 9. ascii horizontal tab code 9 regardless of character set code written in.

in c, '\t' horizontal tab in character set of source code, regardless of character set of io. integer value of '\t' may/may not 9.

the character set of code , character set of io (e.g. files) commonly same. in 2014, there both ascii (at to the lowest degree ascii codes 0 - 127).

in c, printing '\t' precise;

moves active position next horizontal tabulation position on current line. if active position @ or past lastly defined horizontal tabulation position, behavior of display device unspecified. c11 §5.2.2 2

with ascii, horizontal tab intended not represent printable information, rather command devices. ascii original definition led ambiguity precise action of command device: move next tabulation stop.

given these similar, different meanings, , acknowledging other languages have various meanings, precise meaning highly dependent on situation. hence maintain portability, other situation dependent info needed (e. g. definition or list of tab stops) precisely generate , interpret horizontal tab.

recommend: unless info format requires ( csv, makefile), not generate tabs, spaces. upon reading '\t', interpret it, able, same 1 or more consecutive spaces.

neo4j - Matching pattern with optional nodes -

i have cypher query tries capture nodes in order:

a:genus-->b:family-->c:order-->d:class-->e:phylum

with labels genus, family, order, class, phylum , homecoming similar table below.

each of nodes a:e have other properties in reality, nodes may linked in next manner

a:genus --> b:no_rank --> c:family --> d:class --> e:no_rank --> f:phylum

how capture such construction pattern may miss label or have additional nodes in between single query.

currently cypher query looks this:

start basetaxa=node:ncbitaxid('taxid:2006379') match basetaxa-[:childof*0..]->(genus:`genus`)-[:childof*0..]->(family:`family`)-[:childof*0..]->(order:`order`)-[:childof*0..]->(class:`class`)-[:childof*0..]->(phylum:`phylum`) homecoming genus.taxid,family.taxid,order.taxid,class.taxid,phylum.taxid;

i working in android. want info table_main of entries have :

this can done correlated subqueries:

javascript - js-ctypes: Pointer to intptr_t -

javascript - js-ctypes: Pointer to intptr_t -

in ctypes have

tbbutton.ptr(ctypes.uint64("0x1e677e60")

this equivalent abutton.address() in line of code here:

var rez = sendmessage(htoolbar, 0x417 /** tb_getbutton **/, 1, abutton.address());

when run code error:

exception: expected type intptr_t, got tbbutton.ptr(ctypes.uint64("0xaa4eb20"))

so because in sendmessage defintion have this:

var sendmessage = user32.declare('sendmessagew', ctypes.winapi_abi, ctypes.intptr_t, ctypes.voidptr_t, // hwnd ctypes.uint32_t, // msg ctypes.uintptr_t, // wparam ctypes.intptr_t // lparam );

so question is: type of tbbutton.ptr(ctypes.uint64("0x1e677e60") can alter lparam in sendmessage defintion type.

or alternatively: possible create intptr_t? ctypes.intptr_t(abutton.address()), tried doesn't work.

it pointer tbbutton, whatever tbbutton is, while intptr_t integer big plenty hold pointer address.

you need cast pointer intptr_t.

var lparam = ctypes.cast(tbbuttonptr, ctypes.intptr_t);

googling around found several possible solutions issue:

1) remove daemonize imports /opt/graphite/lib/carbon/util.py (https://answers.launchpad.net/graphite/+question/239063):

from time import sleep, time twisted.python.util import initgroups twisted.scripts.twistd import runapp # twisted.scripts._twistd_unix import daemonize # daemonize = daemonize # backwards compatibility

2) utilize twisted 13.1.0 instead of higher twisted version.

3) install daemonize via pip , import directly (https://www.digitalocean.com/community/tutorials/installing-and-configuring-graphite-and-statsd-on-an-ubuntu-12-04-vps):

# twisted.scripts._twistd_unix import daemonize import daemonize

what stable , proven solution twisted environment prepare import issue?

option (2) sounds best alternative me - particularly if can find documentation graphite team twisted 13.1 beingness supported version of twisted (they should document supported versions of dependencies).

with alternative (1) you're diverging installation upstream. going admin headache.

i'm pretty sure alternative (3) won't help. daemonize module related in has same name , vaguely same thing. not drop-in replacement, though.

python 2.7 - subprocess.popen(replacing a parameter from a list and place it on a command) -

it's first week python, apologize in advance if question sounds stupid.

basically wrote code:

__author__ = 'houssam' import subprocess subprocess import popen, pipe check = subprocess.popen(["winexe", "--system", "-u","mydomain\\myusername%mypassword", "//computername", "cmd /c c:\\windows\\system32\\inetsrv\\appcmd list site"],stderr=subprocess.pipe, stdout=subprocess.pipe) (stdout,stderr) = check.communicate() if check.returncode == 0: print 'iis installed on scheme in location below:' print stdout elif check.returncode == 1: print 'iis not installed on scheme ' , stderr

so can query iis of specific computer "//computername" , works.

however have 20 computers. want create list list = [computer1,computer2,computer3] , have function does: each c in list replace name of computer unique parameter "//computername" within subprocess.check_output calls winexe command don't have write command computers have.

i appreciate help , suggestions.

thank you,

houssam

i found answer:

i created list of servers

servers = [//computer1", "//computer2"]

then added statement , set list within popen follow:

server in servers: check= subprocess.popen(["winexe", "--system", "- u","mydomain\\myusername%mypassword", server, "cmd /c c:\\windows\\system32\\inetsrv\\appcmd list site"],stderr=subprocess.pipe, stdout=subprocess.pipe) (stdout,stderr) = check.communicate() if check.returncode == 0: print 'iis installed on scheme in location below:' print stdout elif check.returncode == 1: print 'iis not installed on scheme ' , stderr

then set in function follow:

def iis_check(servers): server in servers: check= subprocess.popen(["winexe", "--system", "- u","mydomain\\myusername%mypassword", server, "cmd /c c:\\windows\\system32\\inetsrv\\appcmd list site"],stderr=subprocess.pipe, stdout=subprocess.pipe) (stdout,stderr) = check.communicate() if check.returncode == 0: print 'iis installed on scheme in location below:' print stdout elif check.returncode == 1: print 'iis not installed on scheme ' , stderr

the urlpatterns has:

the source function is:

this function work in progress, , intended farther refinement.

the development server's console output shows 1 or 2 hits without server error, before displaying error output above. (the page references /ajax/say supposed give brain dump every second, , happens initial bit out putout without error, 500 every sec after that.) non-error output is:

i'm guessing i'm trying create session object string or non-integer id, or that, i.e. first run creates pollution affects sec , subsequent goes. "session" not django's session, empty (django model) class used create unique integer key.

--update--

in response dhana, models defined project are:

from django.contrib.auth.models import user django.db import models unixytalk import settings class room(models.model): identifier = models.charfield(max_length = settings.max_hash_length, null = true, blank = true) class session(models.model): pass class individualcontribution(models.model): room = models.foreignkey(room) session = models.integerfield() text = models.textfield() timestamp = models.floatfield() username = models.textfield()

i think error here

instance = individualcontribution.objects.filter(session = request.session, room = room)[0]

when querying data,it gives error

typeerror: int() argument must string or number, not 'sessionstore'

it asking string or number providing sessionstore.

if provide individualcontribution model details give more details.

i'm trying search using string tables didn't seem work in blob columns. got procedure forum. it's working in searching string not in blob. can please help me please?

create or replace procedure find_string( p_str in varchar2 ) authid current_user l_query long; l_case long; l_runquery boolean; l_tname varchar2(30); l_cname varchar2(30); l_x number; begin dbms_application_info.set_client_info( '%' || upper(p_str) || '%' ); x in (select * user_tables ) loop l_query := 'select ''' || x.table_name || ''', $$ ' || x.table_name || ' rownum = 1 , ( 1=0 '; l_case := 'case '; l_runquery := false; y in ( select * user_tab_columns table_name = x.table_name ) loop l_runquery := true; l_query := l_query || ' or upper(' || y.column_name || ') userenv(''client_info'') '; l_case := l_case || ' when upper(' || y.column_name || ') userenv(''client_info'') ''' || y.column_name || ''''; end loop; if ( l_runquery ) l_case := l_case || ' else null end'; l_query := replace( l_query, '$$', l_case ) || ')'; begin execute immediate l_query l_tname, l_cname; dbms_output.put_line ( 'found in ' || l_tname || '.' || l_cname ); exception when no_data_found /*select 0 l_x dual;*/ dbms_output.put( '.'); end; end if; end loop; end;

thank much!

you cannot search strings within blob column using normal sql string operations. need utilize dbms_lob bundle accomplish goal.

refer this link illustration of how done. there plenty of examples on google can guide further.

c# - Why is it so difficult to find the printer status in windows? -

using c# - i'm trying find list of printers local , online (i.e. connected , ready take print requests)

i know printer driver works - jobs wait until printer online, need find specific online. these available windows .net framework doesn't seem accurately expose online.

i'm trying utilize lots of different methods , none seem accurately work

// list of available printers. var printserver = new printserver(); var printqueues = printserver.getprintqueues(new[] { enumeratedprintqueuetypes.local, enumeratedprintqueuetypes.connections }); foreach (printqueue printqueue in printqueues) { console.writeline(printqueue.isoffline); // works isoffline, doesn't tell online - , it's not inverse relationship }

very frustrating - help appreciated.

should add together i'm using windows 8.1, , solution should work win 7+

edit:

so given next collection of printers :

i expect see along lines of

Session getting destroyed when ajax call is made in rails application -

Session getting destroyed when ajax call is made in rails application -

i have ruby on rails site. applicationcontroller looks like

class applicationcontroller < actioncontroller::base protect_from_forgery before_filter :handle_cookie default_marketplace = 1 def handle_cookie if (session[:isimpersonation].nil?) puts "initilized 0" session[:isimpersonation] = 0 end end

i initializing variable isimpersonation in session object if nil. when normal request made (i.e non-ajax) variable initialized 1 time once i.e. session object retains variable isimpersonation.

but when create ajax phone call like:

$.ajax({ url : "/a/fetch", type : "post", info : { rundate : $('#rundate_select :selected').val(), id : idval, mp : mpval }, beforesend : function(xhr) { xhr.setrequestheader('x-csrf-token', $('meta[name="csrf-token"]') .attr('content')); }, success : function(data) { var $elem = $('<div>').html(data); $("#overall").html( $elem.find('#overall').html()); }, error : function(data) { } });

during ajax phone call variable in session re-initialized. searched , followed post: rails not reloading session on ajax post.

but, not working me. thought missing?

finally, got working. missing:

opengl es - Cocos2d - only one scheduler called -

opengl es - Cocos2d - only one scheduler called -

i'm trying trace 2 paths on screen through series of vertices (connect dots style). each should different color, , each has own list of vertices.

i started out creating class can trace path, creating 2 instances of class, 1 each path. overrode draw method. worked fine except reason first instance of class called draw method. figured problem opengl did 1 time again using ccdrawnode , still had same bug.

only 1 instance (blackpath) draws objects on screen. in fact scheduled updateendpoint: method not called whitepath object, although created.

my drawer.m class:

const float size = 10; const float speed = 5; cccolor4f pathcolor; int numpoints; nsarray * path; cgpoint endpoint; @implementation drawer -(id)initwithpath:(nsarray*)p andcolorisblack:(bool)isblack{ self = [super init]; // record input path = p.copy; pathcolor = ccc4f(1.0f, 1.0f, 1.0f, 1.0f); if(isblack){ pathcolor = ccc4f(0.0f, 0.0f, 0.0f, 1.0f); } // set variables numpoints = 1; endpoint = [[path firstobject] position]; nslog(@"drawer initialized path of length %u , color %hhd (isblack)", p.count, isblack); [self schedule:@selector(updateendpoint:)]; homecoming self; } -(void)updateendpoint:(cctime)dt{ nslog(@"(%f, %f, %f, %f) path", pathcolor.r, pathcolor.g, pathcolor.b, pathcolor.a); [self drawdot:endpoint radius:size color:pathcolor]; cgpoint dest = [[path objectatindex:numpoints] position]; float dx = dest.x - endpoint.x; float dy = dest.y - endpoint.y; // new coords current + distance * sign of distance float newx = endpoint.x + min(speed, fabsf(dx)) * ((dx>0) - (dx<0)); float newy = endpoint.y + min(speed, fabsf(dy)) * ((dy>0) - (dy<0)); endpoint = ccp(newx, newy); if(endpoint.x == dest.x && endpoint.y == dest.y){ if(numpoints < path.count-1){ numpoints+=1; } else{ [self unschedule:@selector(updateendpoint:)]; } } }

and here instantiate objects:

-(id) init{ self = [super init]; [self addallcards]; [self addscore]; xshrinkrate = [[grid getinstance] sqwidth] / shrinktime; yshrinkrate = [[grid getinstance] sqheight] / shrinktime; droplist = [nsmutablearray new]; notdroplist = [nsmutablearray new]; [self schedule:@selector(dropcard:) interval:0.075]; [self schedule:@selector(shrinkcards:)]; drawer * whitepath = [[drawer alloc] initwithpath:[[score getinstance] whitepath] andcolorisblack:false]; [self addchild:whitepath]; drawer * blackpath = [[drawer alloc] initwithpath:[[score getinstance] blackpath] andcolorisblack:true]; [self addchild:blackpath]; homecoming self; }

change (non-const) global variables instance variables of class so:

@implementation drawer { cccolor4f pathcolor; int numpoints; nsarray * path; cgpoint endpoint; }

javascript - How to filter/search multidimensional array of objects? -

i have info construction below:

var options = [{ name: "option one", foo: "bar", values: [{ name: "value one", value: "value", options: [{ name: "option two", values: [{ name: "value two", value: "value", options: [] }] }] }] }, { name: "option three", values: [{ name: "value three", value: "value", options: [] }] }];

i need flatten it, filter out properties don't want , maintain knowledge of depth of each object below info structure:

var flattenedfilteredoptions = [{ depth: 0, name: "option one", values: [{ name: "value one", value: "value" }] }, { depth: 1, name: "option two", values: [{ name: "value two", value: "value" }] }, { depth: 0, name: "option three", values: [{ name: "value three", value: "value" }] }];

so want properties of name, values, , value in output. can point me in right direction start or have solution?

thanks all, here did, maintain in mind configuring properties filter isn't quite in configurable, recursion worked:

function flattenoptions(optionsarray, depth, flattenedoptions) { depth = depth || 0; flattenedoptions = flattenedoptions || []; (var = 0; < optionsarray.length; i++) { var alternative = optionsarray[i]; var nextdepth = depth + 1; var flattenedoption = { depth: depth, name: option.name, values: flattenvalues(option.values, nextdepth, flattenedoptions) }; flattenedoptions.push(flattenedoption); } homecoming flattenedoptions; } function flattenvalues(valuesarray, nextdepth, flattenedoptions) { var values = []; (var = 0; < valuesarray.length; i++) { var value = valuesarray[i]; values.push({ name: value.name, value: value.value }); if (value.options.length > 0) { flattenoptions(value.options, nextdepth, flattenedoptions); } } homecoming values; }

[httppost] public actionresult postresults(formcollection form) { list<selectedanswer> selectedanswers = new list<selectedanswer>(); (int = 0; < 15; i++) { //this part not working... selectedanswers.add(new selectedanswer() { questionid = form["questions"][i].objectid; answerid = form["questions"][i].selectedanswer} } //continue other stuff }

my ultimate goal save selected values database.

got working

(int = 0; < 15; i++) { long x = int64.parse(form[string.format("questions[{0}].objectid", i)]); long y = int64.parse(form[string.format("questions[{0}].selectedanswer", i)]); if (x > 0 && y > 0) { selectedanswers.add(new selectedanswer() { questionid = x, answerid = y }); } }

haskell - Passing different number of the arguments -

i have this:

(aeson.object jsonobject) -> case (hashmap.lookup "high" jsonobject, hashmap.lookup "low" jsonobject) of (just (string val), (string val2)) -> [val, val2] _ -> error "couldn't both keys"

i'd able pass "high" , "low" arguments , pattern matching on them retrieve actual values json. and, of course, number of such arguments can vary.

parsejson :: [string] -> [string] parsejson keys = (aeson.object jsonobject) -> case (?????) of (?????) -> ???? _ -> error "couldn't retrieve keys"

how can this?

try this. assume (aesonobject.jsonobject) refers case of existing case expression, it's not syntactically valid otherwise.

import control.monad ( sequence ) getstring (just (string value)) = value getstring _ = nil parsejson :: [string] -> [string] parsejson keys = case ... of (aeson.object jsonobject) -> case sequence (map (getstring . flip hashmap.lookup jsonobject) keys) of values -> values _ -> error "couldn't retrieve keys"

flip hashmap.lookup jsonobject gives lookup function key value (which maybe. composing getstring gives succeeds on string values, in same way existing inline pattern-match does.

finally, sequence on maybe monad turns [maybe string] maybe [string], returning just output if elements of input just.

ruby - My rack middleware in Rails 4 not executing -

ruby - My rack middleware in Rails 4 not executing -

i trying build cms application using ruby on rails 4.inorder proper controller.i need preprocess querystring before using it in match method shown below

# config/routes.rb cms::application.routes varparameter=env["query_string"] @controller=preprocessqstring(varparameter) match '/cms/home', to: 'login#show', via: [:get, :post] match 'cms/:content(/:action(/:id(.:format)))',to: @controller+'#show', via: [:get, :post] end

to set env["query_string"] using next rack middleware

# lib/httpvariables.rb require 'rack' class httpvariables def initialize(app) @app = app end def call(env) @status, @headers, @response = @app.call(env) request=rack::request.new(env) env["request_uri"]=request.env["request_uri"] env["query_string"]=request.env["query_string"] env["server_port"]=request.env["server_port"] env["server_protocol"]=request.env["server_protocol"] [@status, @headers, self] end end

i have added line in application.rb

# config/application.rb config.middleware.use rack::httpvariables

to suprise if seek start rails server it's failing showing:

mundile@mundile-hp:~/ror-workspace/workspace/cms$ rails server => booting webrick => rails 4.1.1 application starting in development on http://0.0.0.0:3000 => run `rails server -h` more startup options => notice: server listening on interfaces (0.0.0.0). consider using 127.0.0.1 (--binding option) => ctrl-c shutdown server exiting /home/mundile/ror-workspace/workspace/cms/config/routes.rb:68:in `block in <top (required)>': undefined method `+' nil:nilclass (nomethoderror)

i need help out there identify cause of problem. seems env["query_string"] giving nil why ? thanks.

i changed middleware code to:

# lib/httpvariables.rb require 'rack' class httpvariables def initialize(app) @app = app end def call(env) request=rack::request.new(env) env["request_uri"]=request.env["request_uri"] env["query_string"]=request.env["query_string"] env["server_port"]=request.env["server_port"] env["base_url"]=request.base_url @app.call(env) end end

this works charm. have used code reply question: rails access request in routes.rb dynamic routes

python - Why do I get an AttributeError when I use scatter() but not when I use plot() -

python - Why do I get an AttributeError when I use scatter() but not when I use plot() -

i wish plot using matplotlib/pylab , show date , time on x-axis. this, i'm using datetime module.

here working code required-

import datetime pylab import * figure() t2=[] t2.append(datetime.datetime(1970,1,1)) t2.append(datetime.datetime(2000,1,1)) xend= datetime.datetime.now() yy=['0', '1'] plot(t2, yy) print "lim is", xend xlim(datetime.datetime(1980,1,1), xend)

however, when utilize scatter(t2,yy) command instead of plot (t2,yy), gives error:

attributeerror: 'numpy.string_' object has no attribute 'toordinal'

why happening , how can show scatter along plot?

a similar question has been asked before as- attributeerror: 'time.struct_time' object has no attribute 'toordinal' solutions don't help.

if utilize int or float type yy don't error scatter():

yy = [0, 1]

vb.net - Function from a referenced library which has function pointers as parameters -

update: changed question match updated code , more specific problem.

i have no experience working vb.net or visual studio, , limited experience c. have been trying larn function pointers , delegates still don't understand them.

i writing project in vb.net makes calls methods dll file.

c code dll file:

typedef unsigned char byte; typedef unsigned short word; typedef unsigned long dword; typedef void (__stdcall *fp_setbaud)(word); typedef short (__stdcall *fp_get)(word); typedef void (__stdcall *fp_put)(byte); typedef void (__stdcall *fp_flush)(void); typedef void (__stdcall *fp_delay)(word); byte __stdcall initrelay(fp_setbaud _setbaud, fp_get _get, fp_put _put, fp_flush _flush, fp_delay _delay) { ... } byte __stdcall readrelay(void){ ... }

vb.net module code:

declare function initrelay lib "z:\devel\relayapi\debug\relayapi.dll" (byval setbaud action(of short), byval getit func(of short, short), byval putit action(of short), byval flushit action, byval delay action(of short)) byte declare function readrelay lib "z:\devel\relayapi\debug\relayapi.dll" () byte public sub setbaud(byval baud short) ... end sub public function getit(byval timeout short) short ... end function public sub putit(byval dat short) ... end sub public sub flushit() ... end sub public function delayms(byval ms short) short ... end function

vb.net form code:

dim byte phone call initrelay(addressof modulecode.setbaud, addressof modulecode.getit, addressof modulecode.putit, addressof modulecode.flushit, addressof modulecode.delayms) = readrelay()

the error getting when phone call a = readrelay() within vb.net code. error appears on each 1 of parameters , says following:

an unhandled exception of type 'system.accessviolationexception' occurred

the readrelay function uses of functions passed initrelay function. initrelay called prior readrelay , gives me no errors. assuming error still has how passing function pointers initrelay function.

i have been using this website seek figure out type conversions still don't know do.

does have info on should doing phone call these functions?

edit

new delegate declarations suggested below:

private setbauddelegate new action(of short)(addressof modcommstuff.setbaud) private getitdelegate new func(of short, short)(addressof modcommstuff.getit) private putitdelegate new action(of short)(addressof modcommstuff.putit) private flushitdelegate new action(addressof modcommstuff.flushit) private delayitdelegate new action(of short)(addressof modcommstuff.delayms) .... phone call initrelay(setbauddelegate, getitdelegate, putitdelegate, flushitdelegate, delayitdelegate)

i think need pin delegates not garbage collected.

dim handle gchandle = gchandle.alloc(objecttopin, gchandletype.pinned)

don't forget free object after done using .free

handle.free()

more info available @ website. http://manski.net/2012/06/pinvoke-tutorial-pinning-part-4/

update 1

after reading more looks pinning delegates not allowed, still have maintain delegate in memory. seek creating instance variables delegates , keeping them in fields defined in form's code. should plenty maintain delegates getting garbage collected , maintain unmanaged "stubs" getting cleaned up.

along same lines, managed delegates can marshaled unmanaged code, exposed unmanaged function pointers. calls on pointers perform unmanaged managed transition; alter in calling convention; entry right appdomain; , necessary argument marshaling. unmanaged function pointer must refer fixed address. disaster if gc relocating that! leads many applications create pinning handle delegate. unnecessary. unmanaged function pointer refers native code stub dynamically generate perform transition & marshaling. stub exists in fixed memory outside of gc heap.

however, application responsible somehow extending lifetime of delegate until no more calls occur unmanaged code. lifetime of native code stub straight related lifetime of delegate. 1 time delegate collected, subsequent calls via unmanaged function pointer crash or otherwise corrupt process.

update 2 here illustration actual code. did takes single argument, if need adjusted additional arguments allow me know.

private sub initrelay(d1 action(of short)) 'this sub represents initrelay function exported library. wouldn't have straight in code. end sub private sub setbaud(baud short) 'this setbaud sub in module end sub 'this in form code, @ class level (outside subs) private setbauddelegate new action(of short)(addressof setbaud) 'this sub whatever sub in code calls initrelay private sub test() initrelay(setbauddelegate) end sub
