How to enable/disable Toolbar button in Dialog Based MFC application
There is no inbuilt support for this in a Dialog app. You will have to do
the work yourself by essentially copying the code in
CFrameWnd::OninitMenupopup for a menu. Take a look at sample for this at
codeguru. For a toolbar, you will need to do handle WM_KICKIDLE and copy the
code as in a SDI/MDI(I dont know the exact location). Either way, take a
look at codeguru and codeproject for both these tasks.
