I have solved the problem: The bug is NOT in the HTML part, it is in
BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
normal the last lines of this fuction has to be
// otherwise, do default handling
return CExtNCW < CMDIFrameWnd > :: OnCmdMsg( nID, nCode, pExtra, pHandlerInfo );
}
But this code produce the bug. If I change it to
// otherwise, do default handling
CExtNCW < CMDIFrameWnd > :: OnCmdMsg( nID, nCode, pExtra, pHandlerInfo );
return TRUE;
}
How should we users find this bug? NO hint in Your documentation, NO support from Your side
