[Solved] Making a launched process window active

[Josh]

I am using freeprocess to launch and communicate with an external EXE, but the launched window won't activate/become foreground, on top of main program window.

 

My launched process has window activation code like below, but it doesn't work when the process is launched from my main application:

	void Window::Activate()
{
	BringWindowToTop(hwnd);
	SetWindowPos(hwnd,NULL,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);
	SetForegroundWindow(hwnd);
	SetActiveWindow(hwnd);
	SetFocus(hwnd);
	current = this;
}

 

My main application also calls AllowSetForegroundWindow(), to try to give the launched process permission to take the foreground, but it doesn't seem to do anything:

		process=CreateProcess("~q"+procpath+"~q "+parameters)
?win32
	AllowSetForegroundWindow(process.handle)
?

 

How can I allow the window of my launched process to become the topmost window?

AllowSetForegroundWindow() has to be called directly after the new process is created. However, you can use -1 for the process handle, which makes things slightly easier.
