UINT WINAPI WinExec(
  LPCSTR lpCmdLine,
  UINT uCmdShow
);

Where uCmdShow can be any of the following:

SW_FORCEMINIMIZE
Windows 2000/XP: Minimizes a window, even if the thread that owns the window is not responding. This flag should only be used when minimizing windows from a different thread.
SW_HIDE
Hides the window and activates another window.
SW_MAXIMIZE
Maximizes the specified window.
SW_MINIMIZE
Minimizes the specified window and activates the next top-level window in the Z order.
SW_RESTORE
Activates and displays the window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when restoring a minimized window.
SW_SHOW
Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT
Sets the show state based on the SW_ value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application.
SW_SHOWMAXIMIZED
Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED
Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE
Displays the window as a minimized window. This value is similar to SW_SHOWMINIMIZED, except the window is not activated.
SW_SHOWNA
Displays the window in its current size and position. This value is similar to SW_SHOW, except the window is not activated.
SW_SHOWNOACTIVATE
Displays a window in its most recent size and position. This value is similar to SW_SHOWNORMAL, except the window is not actived.
SW_SHOWNORMAL
Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time.

Hi all,

I'm using the GetWindowThreadProcessId function, but for some or other reason the function causes an exception. This is what I'm doing...

<br />
	char* wndName = "WindowName";<br />
	//declaring a handle<br />
	HWND hWnd = NULL;<br />
	//Pointer that receives the process identifier<br />
	LPDWORD lpdwProcessId;<br />
	//return value<br />
	int rc;<br />
	<br />
	//get a window handle<br />
	hWnd = ::FindWindow(NULL,wndName);<br />
<br />
	//get the pid of the process that created the window <br />
	rc = GetWindowThreadProcessId(hWnd,lpdwProcessId);<br />
<br />
	//return the pid<br />
	return rc;<br />

Anyone know what I'm doing wrong??

Thanx in advance

Regards

You're using an uninitialised pointer ("lpdwProcessId"). Try this instead:

const char *pWndName = "WindowName";
 
// Get a window handle
HWND hWnd = ::FindWindow(NULL, pWndName);
 
// Get the pid of the process that created the window
DWORD ProcessId;
DWORD ThreadId = GetWindowThreadProcessId(hWnd, &ProcessId);
 
// Return the pid
return ProcessId;

Again , here you are passing invalid memmory to function GetWindowThreadProcessId.
Use DWORD dwProcessId; instead and pass its address as parameter.
