    Button Displaying Image

    I have a button that displays an image, but there is still like a border around the image. How can i remove it?

    There is a yellow border around the image on the button. Also how can i make the button flat, so that it is not raised?

    I am creating the button like this:
    Code:
    InB = CreateWindowEx(WS_EX_WINDOWEDGE, "BUTTON", "File In", WS_CHILD | WS_VISIBLE | BS_BITMAP,
    			30, 78, 70, 24, hwnd, (HMENU)MAIN_FIN, GetModuleHandle(NULL), NULL);
    Here is what i mean:

    You could also try adding the BS_FLAT style.

    What do i put in place of it?

    EDIT:

    Also I have a checkbox button, how do i change the background color of that, because my current bg color of the window is gray, but the checkbox has some kind of yellowish.

    Null or 0 (zero).

    >>checkbox...change background color of that<<

    Search the boards as this one's been asked and answered many times in the past.

    edit: Actually the situation is a little more complicated because a checkbox is a button control - read this msdn page, which, while old, is still relevant to later operating systems such as winxp. In short, just handle the WM_CTLCOLORSTATIC message send to the checkbox's parent and return a brush which will be used to paint the control background. Make sure you free up any gdi resources you used to create the brush, assuming it's a non-system, non-shared object. For example, something like:
    Code:
    case WM_CTLCOLORSTATIC:
      {
      int nID=GetDlgCtrlID((HWND)lParam);
    
      if (nID==YOUR_CHECKBOX_ID)
        {
        return (LRESULT)GetStockObject(BLACK_BRUSH); /*or your own brush*/
        }
      return DefWindowProc(hwnd,uMsg,wParam,lParam);
      }
    >>He's back!<<

    And just when the standards of the boards were improving, too.
