run a process

[FrenchTroll]

Hello,

How do you do to run a process in a new desktop after switching in it ?

I try like this but that don't work (the process run always in the default desktop) :

$OriginalThread = DLLCall("kernel32.dll","int","GetCurrentThreadId")
$OriginalInput = DllCall('user32.dll', 'hwnd', 'OpenInputDesktop', 'int', 0, 'int', 0, 'int', 0x100)
$NouveauBureau = DLLCall("user32.dll","int","CreateDesktop","str","NouveauBureau", "str","","ptr",0,"int",0,"int",0x10000000,"ptr",0)
$Startup = DllStructCreate($tagSTARTUPINFO)
$Process = DllStructCreate($tagPROCESS_INFORMATION)
DllCall('user32.dll', 'int', 'SetThreadDesktop', 'hwnd', $NouveauBureau[0])
DLLCall("user32.dll","int","SwitchDesktop","int",$NouveauBureau[0]) 
DllStructSetData($Startup, "Size", DllStructGetSize($Startup))
DllStructSetData($Startup, "Desktop", DllStructGetData($Startup, "NouveauBureau"))
_API_CreateProcess("", "C:\Windows\Notepad.exe", 0, 0, False, 0, 0, "", DllStructGetPtr($Startup), DllStructGetPtr($Process))
Sleep(2000)
_API_CloseHandle(DllStructGetData($Process, "hProcess"))
_API_CloseHandle(DllStructGetData($Process, "hThread" ))
DLLCall("user32.dll","int","SwitchDesktop","int",$OriginalInput[0]) 
DllCall('user32.dll', 'int', 'SetThreadDesktop', 'hwnd', $OriginalThread[0])
DLLCall("user32.dll","int","CloseDesktop","int",$NouveauBureau[0])

Certainly i make a mistake but i can't fing where...

Thanks !

If you look in my signature you will find the create process function.

inside the STARTUPINFO you can specify the name of the desktop you want your process to be run DO IT BEFORE YOU SWITCH

!Careful keep track of the PID otherwise you will never be able to close that desktop again.

Another thing pointer to NULL strings are different in AUTOIT from C and you cannot use just 0 so

$NouveauBureau = DLLCall("user32.dll","int","CreateDesktop","str","NouveauBureau", "str",Pt_emptyStr,"ptr",Pt_emptyStr,"int",0,"int",0x10000000,"ptr",Pt_emptyStr)
DllCall('user32.dll', 'int', 'SetThreadDesktop', 'hwnd', $NouveauBureau[0])
DLLCall("user32.dll","int","SwitchDesktop",'hwnd',$NouveauBureau[0])

Func Pt_emptyStr()
    $str=""
    $temp = DllStructCreate("char [" & Stringlen($str) + 1 & "]")
     DllStructSetData($temp,1, $str)
    $P_empty = DllStructGetPtr($temp)
    Return $P_empty
EndFunc

is the correct function
