How to use MFC for writting a component?

I am trying to write a visualization component, but I think I am doing something wrong, because as soon as I show the MFC window using ShowWindow, foobar crashes.

I know that there are some components out there that use MFC, the problem is that I am unable to find the source code of any of them.

Can someone give me a link to the source code of a MFC component, or help me with the crash?

Thanks in advance

How to use MFC for writting a component?

I have no experience with components using MFC, but are you sure that you intialize MFC correctly? The MFC documentation should tell you what needs to be done.
 

How to use MFC for writting a component?

Reply #2 –
Because I had a lot of exams I could not reply before. I was not initializating MFC correctly, as I wasn't creating an instance of CWinApp. Thank you!

Other problem I had while working with MFC was that I was doing this (just in case someone having problems with MFC read this):

Code: [Select]
#include "../../SDK/foobar2000.h"
#include <afxwin.h>


foobar2000.h includes windows.h, and that cannot be done before including afxwin.h. So, you have to do it this way:

Code: [Select]
#include <afxwin.h>
#include "../../SDK/foobar2000.h"


But then it will fail miserably to compile because there will be missing definitions (interface, IDataObject...). So you have to include afxext.h too:

Code: [Select]
#include <afxwin.h>
#include <afxext.h>
#include "../../SDK/foobar2000.h"
