Edit Box SetBkColor

Anyone can tell me why this code does not work. The only thing that comes out is that the editbox becomes grey??
I am missing something??

{
PAINTSTRUCT ps;
HWND htest = GetDlgItem(hDlg, IDC_CHANNEL);
HDC hdc = GetWindowDC(htest);
hdc = BeginPaint (htest, &ps);
SetBkMode(hdc, TRANSPARENT);
SetBkColor(hdc, RGB(0, 255, 0));
EndPaint(htest, &ps);
ReleaseDC(htest, hdc);
}

thanks,
see u!

Well... why not handle WM_CTLCOLOREDIT message?

Actually I have tryed to put this code inside a "case WM_CTLCOLOREDIT", but I am not sure how to make it work!!

I am trying to find something around...

Well WM_CTLCOLOREDIT requires you to return a HBRUSH from the handle. That means you can return every brush you need from WM_CTLCOLOREDIT and the edit will draw itself with it.

Code:

---

LRESULT CALLBACK WndProc ( HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam )
{
  static HBRUSH hBrush = NULL;
  switch ( msg )
  {
      case WM_CTLCOLOREDIT:
          {
              if ( hBrush == NULL )
              { // Red color
                  hBrush = CreateSolidBrush(RGB(0xFF, 0x00, 0x00));
              }
          }
          return (LRESULT)hBrush;

      case WM_CLOSE:
        {
            if ( hBrush != NULL )
            {
                DestroyObject((HGDIOBJ)hBrush);
            }
        } break;
  }
}

Now the edit control should be painted red.

Good example. And don't forget to DestroyObject() in WM_CLOSE or something similar.
