Background color in CEdit Control ?
martin:
Yes, m_hYell is a member of the dialog, but the CBrush which owns the handle is
not. Make the CBrush a member variable of the dialog and extract its handle in
OnCtlColor().
I'm sure there is another way to do it, but since you're using MFC it makes
sense (to me) to limit the references to HBRUSH ro the OnCtlColor function
where it is needed.
