change the background of richedit control

Is there anyway to change the background of richedit control to a bitmap or a picture? I can't seem to find any message for changing the background to a picture but will it just change the background if I use its DC and draw the Bitmap onto it (like drawing the bitmap on window)

No, there isn't any built in method. I would just go with drawing the bitmap onto the window, or inserting an OLE object of the picture.

But somehow this code is not working:

Code:

---

          hdc = BeginPaint(rtfhwnd, &ps);
          memhdc = CreateCompatibleDC(hdc);
          SelectObject(memhdc, hbitmap);
          GetObject(hbitmap, sizeof(bm), &bm);
          BitBlt(hdc, 0,0, bm.bmWidth, bm.bmHeight, memhdc, 0,0,SRCCOPY);
          DeleteDC(memhdc);
          EndPaint(rtfhwnd, &ps);

---

NOTE: It works for the main window when I put it under the windows' WM_PAINT Message.

So I think that I need to put it under the WM_PAINT Message of richedit control. And I think that I need to Subclass the richedit control in order to receive the WM_PAINT message..right? If yes, then can you please show me how to subclass the richedit control and will it send me WM_PAINT, and will I be able to paint the background using the above code if I subclass it?

Please:confused:

Add these 2 as global variables:

Code:

---

LRESULT CALLBACK RichEditProc(HWND, UINT, WPARAM, LPARAM);
WNDPROC wOldProc;

---

Add this to the WM_CREATE event.

Code:

---

wOldProc = (WNDPROC)SetWindowLong(hEdit, GWL_WNDPROC, (LONG) &RichEditProc);

---

Add this to the WM_CLOSE event.

Code:

---

SetWindowLong(hEdit, GWL_WNDPROC, (LONG)&wOldProc);

---

This will be your callback for the richedit control.

Code:

---

LRESULT CALLBACK RichEditProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
        switch(uMsg)
        {
                case WM_PAINT:
                              // Add code here;
                 
                default:
                        return CallWindowProc(wOldProc, hWnd, uMsg, wParam, lParam);
        }
}

---

It tried that but it does not paint anything on the richedit box:(

It also gives me an access voilation error message when I try to set its procedure to default at the WM_CLOSE message:(
