Hijack GetWindowLong (and similar) and return style ORed with WS_CAPTION :P.

 

Thanks, We tried  alot of different combinations with WS_CAPTION styles/without. Each time some problem appear - task bar or blinking default buttons. Wish to know how Office handle it - guess it some hidden API method that Microsoft call or some driver thing that set internal user32 caption bits.

 

Regarding the posts earlier on this topic I made:

 

I have managed to alleviate this problem by implementing OnNcPaint where I remove the WS_CAPTION style, call CXTPMDIFrameWnd::OnNcPaint and then add the caption style back. That allows the 2007 frame to participate in tiling.

 

I still have a slight issue where the underlying icons can sometimes be drawn and of course I have to stop in debug and skip your call to remove the WS_CAPTION.

 

This change also seems to affect the "windows key + m" (minimize all apps issue too). When I do the above (leave the WS_CAPTION style on the frame), I find that after minimizing all apps, I can bring our app back to life much more often and when it fails to come back, I can click the icon in the task bar (usually twice) and the app restores to the maximized state.

 

I think the icon display issue (and perhaps the mimizing issue) can be solved by removing and re-adding the WS_CAPTION style settings in CXTPOffice2007FrameHook::OnHookMessage at the appropriate (yet to be determined) places. It does seem odd to me that since you are drawing your own frame, that you even let OnNcPaint call the default message handler (CXTPMDIFrameWnd does not implement OnNcPaint when the office 2007 theme is running).
