(VS2008, MFC, feature-pack) Using a CTreeCtrl, I need to have the selected item "better" highlighted when the control looses focus.

Hello, I was wondering how visual studio associates mfc CDialog derived classes with their corresponding dialog resources. I'm not interested in how the connection is made at run time (as asked here), but rather at design time. When I add a message handler to a dialog, how does it know which class to add the handler to. Also, is it pos...

I've tried adding '\n' to the string I pass when han...
