Actually, recently I have encountered similiar problem with TheIDE as well. Maybe something is broken with shutdown/exit code (and it is not TrayIcon related).

Just to explain, shutdown/exit code is montrous U++ implementation feature that forces regular exit of U++ application through GUI_APP_MAIN in case of system shutdown. The problem is that Win32 simply posts a message to application, but then quits it immediately, which is a little bit problematic as you are in the WindowProc at the moment - rest of GUI_APP_MAIN is not performed in that case.

U++ therefore starts "overwatch thread" at the start of Win32 GUI app. This thread opens single off-screen window and its purpose is to keep U++ application "alive" until GUI_APP_MAIN finishes.

This extremely fragile code starts at line 82 of CtrlCore/Win32Wnd.cpp. I will look into it ASAP, but maybe you will notice some problem there too....

Actually, I do not think you should fix it in your client code. This must be fixed in U++ (because the code is already there).

If you want to try some hacking, it is still the code starting at line 82 of CtrlCore/Win32Wnd.cpp - that is the most probable cause of broken behaviour.

OK, I think I have hunted this bug down (pretty messy bussines, I had to shutdown the computer 20 times to get all needed info Wink

.

I think the problem should be fixed by adding two lines at the beginning of GuiSleep routine (Win32Wnd.cpp around line 670):

void Ctrl::GuiSleep(int ms)
{
	if(EndSession())
		return;
....

Please check whether this helps.

Please, be more specific. Error or that window about application not closing when shutting down Windows?

OK, another try:

void Ctrl::ExitWin32()
{
	sFinished = true;
	for(int i = 0; i < Windows().GetCount(); i++) {
		HWND hwnd = Windows().GetKey(i);
		if(hwnd)
			::DestroyWindow(hwnd);
	}
	MSG msg;
	while(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
		if(msg.message != WM_QUIT)
			::PostQuitMessage(0);
#ifndef flagDLL
#ifndef PLATFORM_WINCE
	OverwatchEndSession.Set();
	PostMessage(OverwatchHWND, WM_USER, 0, 0);
	LLOG("Waiting for overwatch thread to finish...");
	WaitForSingleObject(OverwatchThread, INFINITE);
	LLOG("...overwatch thread finished");
#endif
#endif
}

Seems to work OK for me now, but unfortunately, the problem is too erratic to judge anything... (otoh, the bug in the code seems to be quite obvious and inline with behaviour).

Please check it ASAP.
