remote assistance using msra exe , arguments.

here have designed class , form, , gives next functionalities,

offer remote assistance machine ask remote help. (invite help you)

design form next controls,

textbox taking ip or computer name connect button 1. connect remote machine offering remote assistance button 2. inquire or invite help.

code behind in form:

using system; using system.collections.generic; using system.componentmodel; using system.drawing; using system.text; using system.windows.forms; namespace remoteassist { public partial class frmconnect : form { public frmconnect() { initializecomponent(); } private void btnconnect_click(object sender, eventargs e) { remoteconnect remoteconnect = new remoteconnect(); boolean status = remoteconnect.startremoteassistance(txtcomputername.text.tostring(), true,false); if (status == false) { system.windows.forms.messagebox.show("unable connect remote machine.please seek 1 time again later."); } } private void btninvite_click(object sender, eventargs e) { remoteconnect remoteconnect = new remoteconnect(); boolean status; status = remoteconnect.startremoteassistance(txtcomputername.text.tostring(), false, true); if (status == false) { system.windows.forms.messagebox.show("unable found connection, please seek 1 time again later."); } } private void frmconnect_load(object sender, eventargs e) { } private void txtcomputername_textchanged(object sender, eventargs e) { txtcomputername.charactercasing = charactercasing.upper; } } }

we have 2 buttons here , sending boolean variable class function differentiating between offer help , asking help.

code under class file : remoteconnect

using system; using system.collections.generic; using system.linq; using system.text; namespace remoteassist { class remoteconnect { public boolean startremoteassistance(string strmachinename, boolean offerhelp, boolean askforhelp) { system.diagnostics.process process = new system.diagnostics.process(); system.diagnostics.processstartinfo startinfo = new system.diagnostics.processstartinfo(); startinfo.windowstyle = system.diagnostics.processwindowstyle.maximized; startinfo.filename = "msra.exe"; // offer remote assitance if (offerhelp == true) { startinfo.arguments = "/offerra " + strmachinename; } //ask remote assistance if (askforhelp == true) { startinfo.arguments = "novice"; } seek { process.startinfo = startinfo; process.start(); homecoming true; } grab (exception ex) { //system.windows.forms.messagebox.show("error occured while trying connect" + ex.message); homecoming false; } } } }
