Crash in USER.EXE

[Nosferatu]

The crash is generated with a call to DestroyWindow(HWND), and the window still has input focus (that would mean the caret is still in the window -and blinking...-).

Anybody has any idea why that hapens?

The window is placed on a toolbar, and the whole program is based on winAPI only, no COM objects at all.

Could be your HWND value is invalid. Just a wild guess with nothing to go on.

I'm sure that the HWND is invalid but how can i figure out why that happens???
I've printed its value, but how do i know that it is valid or not? It's just a number, after all. Are there any functions that can tell me that?

IsWindow
The IsWindow function determines whether the specified window handle identifies an existing window.

BOOL IsWindow(
HWND hWnd // handle to window
);


Good luck
