ShowPane when opening a dialog box

void CMainFrame::OnGo()

{

CXTPDockingPane* pPane = m_paneManager.FindPane(1);

m_paneManager.ShowPane(pPane);

CMyDialog aDlg;

aDlg.DoModal();

}

My problem is that the Pane becomes visible only after the dialog-box is closed (even though the call to ShowPane was first). I must have the Pane visible when the modal dialog is alive. How can I do it ?

thanks, Iris.
