CONTEXTHELP

[Otto]

Can you add a question mark button to a WINDOW's caption bar and if yes how?
Thanks in advance

Hello, Otto!
It has to be something like:
#define WS_EX_CONTEXTHELP 1024
#define GWL_EXSTYLE (-20)
SetWindowLong( oWnd:hWnd, GWL_EXSTYLE, nOr( GetWindowLong( oWnd:hWnd, GWL_EXSTYLE ), WS_EX_CONTEXTHELP ) )
But for me it's also doesn' work... I can't understand the reason...

Hello Sergey,

I found this topic in an non FW-forum:

http://codeguru.earthweb.com/forum/show ... hp?t=46721

I know that for some reason, microsoft has decided that WS_EX_CONTEXTHELP (the question-mark
box) and WS_MINIMIZEBOX / WS_MAXIMIZEBOX aren't allowed to coexist in the same title bar.
This is by design.

Maybe it is not possible to have a „question-mark box” on a window.


Best regards,
Otto
