I have an MFC button on my dialog.  I wich to use bitmap buttons to give it a nice look.  When I do the following:

CBitmapButton bmpOpt1;
m_bmpOpt1.SubclassDlgItem( IDC_BUTTON_1, this );
m_bmpOpt1.LoadBitmaps(IDB_BITMAP_GREENNEW, IDB_BITMAP_GREENNEW, 0, IDB_XPBTNMENUDIS_BITMAP);

I get an assert error on the second line above:
m_bmpOpt1.SubclassDlgItem( IDC_BUTTON_1, this );

The assert error is:
Debug Assert Failed
File: f:\sp\vctools\vclibsce\ship\atlmfc\src\mfc\wincore.cpp Line 375;
Abort | Retry | Ignore


Why is this??

I have just realised that I have a handler for this button already:

DDX_Control(pDX, IDC_BUTTON_1, m_button1);

could this be causing problems???

YES!!!! :)

look at that line and the very next:

      ASSERT(FromHandlePermanent(hWndNew) == NULL);
            // must not already be in permanent map <-- HERE
