Re: check if programme exist with HWND

Ok, now I ask myself what happens in Windows with the "lost" message.
Do you think, Windows or my application can crash if I send a message to a
HWND that no longer is valid?
Should I use try-catch with SendMessage?
Regards, Guido
if(IsWindow(hWnd)) // is a window
{
// crashes
SendMessage(WM_COPYDATA,...); // lost
}
so there is no guaranteed way to do this reliably.
