Hello,

This is my first question posted on this forum.

I encounter an debug exception in MFC code after I change the skin of my application.
The application has lots of existing MFC components and I added a ribbon bar and docking pane manager to an MDI MainFrame.

The call stack leads to MFC code CControlBar::OnCtlColor with comments "force black text on gray background all the time". Inside CWnd::GrayCtlColor exists a verify assertion that fails:

VERIFY(::GetObject(hbrGray, sizeof(LOGBRUSH), (LPVOID)&logbrush));

The call stack after the skin change:

CWnd::GrayCtlColor(HDC__ * hDC, HWND__ * hWnd, unsigned int nCtlColor, HBRUSH__ * hbrGray, unsigned long clrText) Line 4356
CControlBar::OnCtlColor(CDC * pDC, CWnd * pWnd, unsigned int nCtlColor) Line 686
CWnd::OnWndMsg(unsigned int message, unsigned __int64 wParam, __int64 lParam, __int64 * pResult) Line 2341
CWnd::WindowProc(unsigned int message, unsigned __int64 wParam, __int64 lParam) Line 2087
CControlBar::WindowProc(unsigned int nMsg, unsigned __int64 wParam, __int64 lParam) Line 506

...

CXTPSkinManager::OnSkinChanged(int bPrevState, int bNewState) Line 1118

I am posting this question because I do not see any of our own code involved.
Do you have any idea what I might be doing wrong, or how I can continue to investigate (if it is a serious issue)? 

MFC version 10 (of toolkit v100 of Visual Studio 2010)
ToolKit Pro MFC: 19.3.0

Kind regards,
Peter
