Things don't work that way.

You will have to use owner draw buttons.
See if you can find one here that suits you

I am working with arrays of CBitmapButtons but the bitmaps themselves
are dynamic. I need to be able to create them at runtime. Once I have a
bitmap and I have drawn what I want on it how do I make it look like a
resource so I can use the CBitmapButton::LoadBitmaps() function to set
it up?

I don't think I have to subclass the control if I can do this.

thanks

nap.

I managed to do it by subclassing the CBitmapButton and adding this:

int CBmpBtn::SetBmp(CBitmap &bitmap,int state)
{

HANDLE hbitmap;
hbitmap = bitmap.operator HBITMAP();

switch(state)
{
case 0:
    m_bitmap.Attach(hbitmap);
break;
case 1:
    m_bitmapSel.Attach(hbitmap);
break;
case 2:
    m_bitmapFocus.Attach(hbitmap);
break;
case 3:
    m_bitmapDisabled.Attach(hbitmap);
break;

return 1;

}

Seems to work.. Is this wrong?

Looks fine.

Just make sure that you call DeleteObject before the Attach.

m_bitmap.DeleteObject();
m_bitmap.Attach(hbitmap);

good one. Many thanks.
