Thread: Remove dialog button border

I'm having a problem with the dialog button control. I have loaded a bitmap over the button (successfully), however, the border around the button remains. I've made sure that there's nothing specifying borders checked under properties, and I've even double checked by opening my program with a resource editor and checking that WS_BORDER isn't a style for the button. Is there any way to just have a flat bitmap button?

It looks like you'r printing the bitmap in the parent window's callback and HDC. You need to do it in the button's own callback and HDC. Give the button the style BS_FLAT too.

I'm sending a message directly to the button on the dialog with

Code:

SendDlgItemMessage(hDlg, IDC_OKAYBUTTON, BM_SETIMAGE, (WPARAM)IMAGE_BITMAP, (LPARAM)LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_OKAY)));

. The button is actually a button control, not a button done with CreateWindow. If I used GetDC and all that to draw within the button wouldn't it still be limited to the frame? Currently everything "works" so to speak, it's just that if I have an 80x20 pixel bitmap and an approx. 60x10 button then only 60x10 of the bitmap will be displayed.

Since you already seem to be attempting to draw it, I'd suggest going all the way with an owner-drawn button by giving the control the BS_OWNERDRAW style and handling the parent's WM_DRAWITEM message.

Perfect, this works exactly as planned. Thanks.
