I used following function

HBRUSH CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
return m_brush;
}

along with the line m_List.SetBkColor(RGB(255, 255, 255));
in oninitdialog().

I'm not sure, how you have done it, but modify your code to,

CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
return m_brush;
}</blockquote>

To skip edit control painting do this,
HBRUSH CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
m_brush= CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (nCtlColor == CTLCOLOR_EDIT)
{
return brush
}
else
{
//do your customized painting
}

return m_brush;
}

Hope the m_List is your CEdit control.

Instead of simply returning m_brush(hope this the brush to paint the dialog background). Try this,

CFileopenDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
 HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
 if (CTLCOLOR_EDIT != nCtlColor)
   return m_brush;
 return hbr;
}

The above change the background color for all the controls in the dialog except for the CEdit controls.
If you want to change the color only to the dialog then change the 'if' condition as below

if (CTLCOLOR_DLG == nCtlColor)

Default color of editbox is white but if you want to change color of editbox use of WM_CTLCOLOREDIT

Over ride WM_ERASEBKGND and put this code over there.

CPen myPen;
int i =100;
CRect rect ;

myPen.CreatePen(PS_SOLID, 1, RGB ((i * 4),0,0));
CPen *oldPen = pDC->SelectObject(&myPen) ;
GetClientRect(&rect);
for(i = 0 ; i <= rect.bottom;)
{
pDC->MoveTo(0, i);
pDC->LineTo(rect.right, i);
pDC->SelectObject (&myPen);
}
pDC->SelectObject(oldPen) ;
return TRUE ;

The edit box would not be painted to match the dialog back color and would show as white. See if this helps

if (pWnd->GetDlgCtrlID() == IDC_EDIT1) would be better.

CString: Heap Vs Stack?

Does CString allocate memory on the heap or on the stack?

The memory for the character array is on the heap.

CString uses heap to create char array.

devvvy wrote:

strNewString = strOriginal.Mid(2);
oList.AddTail(strNewString);

Actually, CString class uses class CStringData, which keeps tack of this buffer using reference counting.
In this case AddTail cause to increase refernce count by 1, thats why buffer contained in strNewString will not be destroyed even though object goes out of scope.

Send custom message to dialog, which has the tab. Handle the message in the dialog and close it as you like (say OnOK or OnCancel or EndDialog ...)

or

If the dialog is the parent winodw for the tab then simply call
GetParent()->EndDialog(..);

Hope i understood your question..

Just use the tabdialog instance to call its method (make sure the access specifier for the methos is public)
