I am trying to learn MFC but here is the question for which I was unable to find the answer. Given this class definition: int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { What does it exactly do? CMainFrame derives from OnCreate class? What do arguments of the OnCreate class do? I would appreciate any help.

CMainFrame derives from OnCreate class? You should post this topic to a MFC group: microsoft.public.vc.mfc In this case, the original poster should back off of MFC and then learn C++ from scratch. Nothing in the MFC documentation will assume you don't know C++. Write simple console programs first... ....or switch to a softer language, such as HTML or Visual Basic, if you just want to create a window with some buttons on it. -- Phlip http://flea.sourceforge.net/PiglegToo_1.html Back to top Massimo Guest Posted: Sun May 13, 2007 9:11 am    Post subject: Re: MFC question "Tadeusz Jordan" <tedjj (AT) poczta (DOT) onet.pl> ha scritto nel messaggio news:f25p14$gki$1 (AT) news (DOT) onet.pl...

Given this class definition: int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { What does it exactly do? CMainFrame derives from OnCreate class? What do arguments of the OnCreate class do? You should *definitely* learn C++ before trying to learn MFC. An then, you really shouldn't be learning MFC, as it's quite an obsolete technology; there are much better ones around now. Anyway, "int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)" means that's the OnCreate() method of the CMainFrame class, and it takes a LPCREATESTRUCT as its first and only argument, returning an int upon completion.

Addendum: based on the Hungarian notation which is often used in Windows programming, I can guess LPCREATESTRUCT is a Long Pointer (LP) to a CreateStruct data type; so it's probably a pointer to a library-defined data structure you must supply in order for the method to use it. That "OnCreate()" is definitely *not* a class definition: it's the implementation of a method declared in the class CMainFrame, which, I'm again guessing, is a user-defined frame class, derived from some kind of super-frame-class declared in the MFC library.
