Until now, I never really needed the Winapp ExitInstance() of a large MFC (Single Document Interface if it matters) app I'm working on. But now I do, mainly to cleanup memory alocations, unload some DLLs, etc. Well I soon learned by the obvious memory leaks and such that ExitInstance was not being called. Have I missed something obvious?...
Dear All, I would like to add transparency and shading to my application written using MFC and Visual Studio 2008 Prof. At the moment I am using Ribbons which makes the app look good but the mainframe (is a CFormView based app) is terrible!

Dear All, I would like to strecth horizontally the image of the ribbon (possibly also veritcally..). I found the virtual function StretchHorizontally() (http://msdn.microsoft.com/en-us/library/cc701788.aspx) but unfortunately I have no idea on what to write in the code. I assume I have to extend the CMFCRibbonButton class and implement...
