Question : CEdit bmp background

I have tiled a bmp image to create a background for my CEdit object.  This works fine, except when text is selected.  The problem is that when the text is unselected the background of where the text selection was is now white instead of my bmp.  I need a solution to this problem.  I have thought of two possible ways to get around this:

1)
Make it so text selection doesnt highlight the background (it only changes the actual text color).

2)
Have the background redraw when the text selection is gone.

The problem is I'm not sure how to implement either of these solutions.

Here is the code I have to place the background bmp.

pDC->SetBkMode(TRANSPARENT);
            CRect rect;
            this->GetWindowRect(&rect);
   
            CDC* pMemDC = new CDC;
            CBitmap*     pBitmap = new CBitmap;


            pBitmap->LoadBitmap(IDB_BITMAP_TEXT);
            pMemDC->CreateCompatibleDC(pDC);
            HBITMAP hBMPDefault = CreateCompatibleBitmap(pDC->m_hDC, rect.Width(), rect.Height());
        SelectObject(pMemDC->m_hDC, hBMPDefault);
            CBitmap*     pOldBitmap = (CBitmap*)pMemDC->SelectObject(pBitmap);

            int cx = 0;
            int cy = 0;
            int nWidth = rect.Width();
            int nHeight = rect.Height();
            BITMAP bm;
            pBitmap->GetBitmap(&bm);
            for (int y=0;y < nHeight; y += bm.bmHeight )
            {
                  for (int x=0;x < 225; x += bm.bmWidth )
                  {
                        if((x+bm.bmWidth) > nWidth)
                              cx = nWidth;
                        else
                              cx = bm.bmWidth;
                        if((y+bm.bmHeight) > nHeight)
                              cy = nHeight;
                        else
                              cy = bm.bmHeight;
                        pDC->BitBlt(x, y, cx, cy, pMemDC, 0, 0, SRCCOPY);
                  }
            }
            pMemDC->SelectObject(pOldBitmap);
            delete pBitmap;
            pMemDC->DeleteDC();
            delete pMemDC;

Answer : CEdit bmp background

The CEdit required a brush object when painting its DC, create a bitmapped brush and return the brush handler in your dialog's OnCtlColor.

class CAboutDlg : public CDialog
{
public:
      CAboutDlg();
      CBrush m_BrushEdit;
...
}

BOOL CAboutDlg::OnInitDialog()
{
      CDialog::OnInitDialog();
      
      // TODO: Add extra initialization here
      CBitmap BitmapEdit;
      BitmapEdit.LoadBitmap(IDB_IMAGE);
      m_BrushEdit.CreatePatternBrush(&BitmapEdit);

      return TRUE;  // return TRUE unless you set the focus to a control
                    // EXCEPTION: OCX Property Pages should return FALSE
}

HBRUSH CAboutDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
      HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
      
      // TODO: Change any attributes of the DC here
      if(pWnd->GetDlgCtrlID()==IDC_EDIT1)
      {
            pDC->SetBkMode(TRANSPARENT);
            pDC->SetTextColor(RGB(255,0,0));
            pDC->SelectObject(&m_BrushEdit);
            hbr=(HBRUSH)m_BrushEdit;
      }

      // TODO: Return a different brush if the default is not desired
      return hbr;
}
