[RESOLVED] starter app not responding

[Paul McKenzie]

The following code results in simple window which stops responding as soon as it is executed.
i really have no idea what is happening, i am just starting visual c++

1) Please use code tags when posting code. The code you posted is almost unreadable.

2) You should take working examples before trying to code a Windows application yourself.

LRESULT CALLBACK windowprocess (HWND hwindow, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch(uMsg)
    {
	case WM_DESTROY: 
		PostQuitMessage(0);
		return 0;
		break;

	case WM_PAINT:
	{
            PAINTSTRUCT ps;
            HDC hdc = BeginPaint(hwindow, &ps);
            FillRect(hdc, &ps.rcPaint, (HBRUSH) (COLOR_WINDOW+1));
            EndPaint(hwindow, &ps);
        }
	break;
//??? So what does WM_PAINT return??
}

Return value

An application returns zero if it processes this message.

You are returning an unknown value back to the OS.

In general, whenever you process a message, you must return what is documented that you return for the particular message. Don't guess, don't leave the return empty, etc. You are to return 0 if you process the WM_PAINT message.

3)

#ifndef UNICODE
#define UNICODE
#endif

Why are you doing this? The build settings already have these preprocessor constants defined for you.
