Hello-

When I try to delete text that I’ve typed in a CExtEdit box, it takes quite a while for the text to actually delete. This can be easily seen in the ProfUIS_Controls sample:

1. Compile & run ProfUIS_Controls MBCS Debug.
2. Select Visual Studio 2005 style
3. Choose "Buttons" on the left of the screen
4. You’ll see a CExtEdit box with the text "tooltip" in it
5. Try highlighting that text, move the mouse off the control, and press the delete key. Nothing happens unless you hover the mouse over the window.
6. Now, try typing "hello" in the same window and press the delete key one time. You’ll see the cursor back up to the left of the ’o’ but not delete it. Again hovering the mouse over the control causes the actual delete to happen.

What gives?

Thanks.

Thank you for the bug report. Please update the following two methods in the ExtEdit.cpp and ExtGridWnd.cpp files:

HBRUSH CExtEditBase::CtlColor( CDC* pDC, UINT nCtlColor )
{
 ASSERT_VALID( this );
 if(  nCtlColor == CTLCOLOR_EDIT 
  || nCtlColor == CTLCOLOR_MSGBOX
  || ( nCtlColor == CTLCOLOR_STATIC )
  )
 {
  COLORREF clrText = GetTextColor();
  if( clrText == COLORREF(-1L) )
  {
   COLORREF clrSysText =
    g_PaintManager->GetColor(
     ( ! IsWindowEnabled() )
      ? COLOR_GRAYTEXT
      : COLOR_WINDOWTEXT
     );
   clrText = clrSysText;
  }
  bool bReadOnly = (GetStyle()&ES_READONLY) != 0;
  COLORREF clrBk = GetBkColor();
  if( clrBk == COLORREF(-1L) )
  {
   COLORREF clrSysBk =
    g_PaintManager->GetColor( 
     bReadOnly 
     ? COLOR_3DFACE
     : COLOR_WINDOW 
    );
   clrBk = clrSysBk;
  }
  pDC->SetBkColor( clrBk );
  pDC->SetTextColor( clrText );
  if( m_clrBackPrev != clrBk )
  {
   if( m_brBack.GetSafeHandle() != NULL )
    m_brBack.DeleteObject();
   m_brBack.CreateSolidBrush( clrBk );
   m_clrBackPrev = clrBk;
  }
  return m_brBack;
 }
 else
  return (HBRUSH)Default();
}
