heartkey Posted January 1, 2010 Share Posted January 1, 2010 Hi guys, and firstly, Happy New Year , So here's my problem: I'm trying since long to call the "CreateProcessW" kernel32.dll in order to start a new program in another desktop location , but the function in question doesn't like my structure... Here's the code: expandcollapse popup#include <Winapi.au3> Desk_StartProgram("c:\windows\explorer.exe", "c:\windows\", "Test") ;"Test" is the name given to the desktop in which the program must be displayed, of course I created the named desktop before. Func Desk_StartProgram($hPath, $hCurrentdir, $hDesktop) Local $tSTARTUPINFO = DllStructCreate("dword cbSize;" & _ "ptr Reserved;" & _ "ptr Title;" & _ "str Desktop;" & _ ; When the "str" of this line is replaced by "ptr" the program is running properly, however it remains in the current desktop (default) "dword X;" & _ "dword Y;" & _ "dword XSize;" & _ "dword YSize;" & _ "dword XCountChars;" & _ "dword YCountChars;" & _ "dword FillAttribute;" & _ "dword Flags;" & _ "ushort ShowWindow;" & _ "ushort Reserved2;" & _ "ptr Reserved2;" & _ "ptr hStdInput;" & _ "ptr hStdOutput;" & _ "ptr hStdError") MsgBox(0,"",_WinAPI_GetLastErrorMessage()) ;returns "The operation was successful." DllStructSetData($tSTARTUPINFO, "Desktop", $hDesktop) MsgBox(0,"",_WinAPI_GetLastErrorMessage()) ; returns "The operation was successful." Local $tPROCESS_INFORMATION = DllStructCreate("ptr Process;" & _ "ptr Thread;" & _ "dword ProcessId;" & _ "dword ThreadId") $aCall = DllCall("kernel32.dll", "int", "CreateProcessW", _ "wstr", $hPath, _ "wstr", "", _ ; CMDLINE "ptr", 0, _ "ptr", 0, _ "int", 0, _ "dword", 4, _ ; deliberately pre-hung "ptr", 0, _ "wstr", $hCurrentdir, _ ; Curent Dir "ptr", DllStructGetPtr($tSTARTUPINFO), _ "ptr", DllStructGetPtr($tPROCESS_INFORMATION)) If @error Or Not $aCall[0] Then MsgBox(0,"",_WinAPI_GetLastErrorMessage()) ; returns "The parameter is incorrect." Return SetError(1, 0, 0) EndIf Local $hThread = DllStructGetData($tPROCESS_INFORMATION, "Thread") DllCall("kernel32.dll", "int", "ResumeThread", "ptr", $hThread) Return DllStructGetData($tPROCESS_INFORMATION, "ProcessId") EndFunc Hoping someone can give me help, because I despair of being able to succeed one day ...

jchd Posted January 1, 2010 Share Posted January 1, 2010 Hi,My reply on the French forum didn't find its way; don't know why.Compare with this thread where Trancexx creates a process (this is the code in code tags, not the attached file).Now str will convert an AutoIt string into ANSI (1char = 1byte) as opposed to wstr where 1 [unicode] char = 1 or 2 16-bit word.Happy New ProcessW This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.Another excellent RegExp tutorial.

trancexx Posted January 1, 2010 Share Posted January 1, 2010 That should always be pointer. It's "ptr Desktop;"Func Desk_StartProgram($hPath, $hCurrentdir, $sDesktop) Local $tSTARTUPINFO = DllStructCreate("dword cbSize;" & _ "ptr Reserved;" & _ "ptr Title;" & _ "ptr Desktop;" & _ "dword X;" & _ "dword Y;" & _ "dword XSize;" & _ "dword YSize;" & _ "dword XCountChars;" & _ "dword YCountChars;" & _ "dword FillAttribute;" & _ "dword Flags;" & _ "ushort ShowWindow;" & _ "ushort Reserved2;" & _ "ptr Reserved2;" & _ "ptr hStdInput;" & _ "ptr hStdOutput;" & _ "ptr hStdError") Local $tDesktop = DllStructCreate("wchar[" & StringLen($sDesktop) + 1 & "]") DllStructSetData($tDesktop, 1, $sDesktop) DllStructSetData($tSTARTUPINFO, "Desktop", DllStructGetPtr($tDesktop)) ;...Or something like that. ♡♡♡ . eMyvnE Link to comment Share on other sites More sharing options...
heartkey Posted January 2, 2010 Author Share Posted January 2, 2010 (edited) Thank you for these answers, trancexx solution works well (run the program properly) but in the current desktop ... Thanks, Anthony. PS: The CPP source code : bool CDesktopManager::LaunchApplication(TCHAR *pszApplicationFilePath, TCHAR *pszDesktopName) { bool bReturn = false; try { TCHAR szDirectoryName[ARRAY_SIZE] = {0}; TCHAR szExplorerFile[ARRAY_SIZE]= {0}; _tcscpy_s(szDirectoryName, _tcslen(pszApplicationFilePath) + 1, pszApplicationFilePath); PathRemoveFileSpec(szDirectoryName); STARTUPINFO sInfo = {0}; PROCESS_INFORMATION pInfo = {0}; sInfo.cb = sizeof(sInfo); sInfo.lpDesktop = pszDesktopName; //Lanuching a application into dekstop BOOL bCreateProcessReturn = CreateProcess(pszApplicationFilePath, NULL, NULL, NULL, TRUE, NORMAL_PRIORITY_CLASS, NULL, szDirectoryName, &sInfo, &pInfo); TCHAR *pszError = NULL; bReturn = true; } return bReturn; } Edited January 2, 2010 by heartkey Link to comment Share on other sites More sharing options...
trancexx Posted January 2, 2010 Share Posted January 2, 2010 cbSize member is not set. If that doesn't help, check that the new desktop is ok. ♡♡♡ . eMyvnE Link to comment Share on other sites More sharing options...
heartkey Posted January 3, 2010 Author Share Posted January 3, 2010 I try to set cbSize with: DllStructSetData($tSTARTUPINFO, "cbSize", DllStructGetSize($tSTARTUPINFO)) But this does not work, badly written ? It never works . Link to comment Share on other sites More sharing options...
