Title: Exec a child process
Post by: Grincheux on October 14, 2019, 07:55:59 PM

I have a window into which I would like to run Google Earth.
With CreateProcess Google Earth runs but outside my program.
How could I do?
I thought searching for the window hadle of Google Earth and setting it has a child window of my program.
Is it a solution?

Do you mean something like this?

Code Select

void DoTest(HWND hWnd)
{
	WinExec(TEXT("notepad.exe"), SW_HIDE);
	Sleep(500);
	HWND hWndChild = FindWindow(TEXT("Notepad"), NULL);
	SetParent(hWndChild, hWnd);
	RECT rect;
	GetClientRect(hWnd, &rect);
	MoveWindow(hWndChild, 0, 0, rect.right, rect.bottom, 0);
	ShowWindow(hWndChild, SW_SHOW);
}

Here is what I did :

WM_CREATE :

   hGoogleEarth = FindWindow("Qt5QWindowIcon",NULL) ;
   SetParent(hGoogleEarth,hMainWindow) ;

into WM_DESTROY :

   SetParent(hGoogleEarth,hMainWindow) ;

The rest is into WM_SIZE

Thank you MS SPY.
