title: Change Color of read only CEdit control Artifacts and Text Highlighting issue
body: <p>I have an Edit control that is read only that has text in it. I would like to switch the default gray background to white but have been having limited luck. In my first go, I was executing the following code during initialization of the dialog:</p>
  
  <pre><code>CEdit *m_ctrlEditOne = (CEdit*) GetDlgItem(IDC_EDIT1);
  CDC *m_ctrlEEditWee = m_ctrlEditOne-&gt;GetDC();
  m_ctrlEEditWee-&gt;SetBkColor(RGB(255,0,0));
  Invalidate(true);
  </code></pre>
  
  <p>Another solution I tried was:</p>
  
  <pre><code>HBRUSH CTestingDlg::OnCtlColor(CDC* pDC, CWnd *pWnd, UINT nCtlColor)
  {
  if (pWnd-&gt;GetStyle() &amp; ES_READONLY)
  //if(pDC-&gt;GetRuntimeClass == &amp; ES_READONLY)
  {
      switch (nCtlColor)
      {
      case CTLCOLOR_STATIC:
          pDC-&gt;SetBkColor(RGB(255,255,255));
          return (HBRUSH)GetStockObject(NULL_BRUSH);
      default:
          //return NULL;
          return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
      }
  }
  //return NULL;
  return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
  }
  </code></pre>
  
  <p>In the screenshot below, you can see that the text is inserted after the fact (this is what needs to happen) and appears highlighted in blue - I have no idea where to begin on how to make it just appear as normal, non-highlighted text. When clicking on it, it appears normally. In the bottom left corners of each edit control, one can see a square which should not be appearing there. Also, you can see some artifacts of what looks like to be a combo box dropdown selection appearing in the larger boxes.</p>

  <p>I would appreciate any pointers on how to get rid of the artifacts and fix the highlighting issue with inserted text.</p>
