Hi,
  I am at present doing a project in VC. I want to have a control, like a chat box,where whatever u type in a small text box can be exhibited in the larger one.
 I found out that combobox can be used for it,with its styles attribute set to simple.But i am not able to store whatever i type in the smaller text box and display in the larger one.
Any of u please help me in this regard.

Thanx,
Thiru

Hi thirumaran,

You can retrieve the edit control's text with CWnd::GetWindowText() and add to combo box with CComboBox::AddString().

Hi again, thirumaran,

here's how I would do it:

// m_cb is the CComboBox member added with ClassWizard
CMyDialog::PreTranslateMessage(MSG* pMsg)
{
 if ( pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_RETURN )
 {
  CWnd* pFocus = GetFocus();

  if ( NULL != pFocus && pFocus->GetParent()->m_hWnd == m_cb.m_hWnd )
  {
   CString t;
   m_cb.GetWindowText( t );
   if ( !t.IsEmpty() )
   {
    m_cb.InsertString( 0, t );
    t = "";
    m_cb.SetWindowText( t );
    return TRUE;
   }
  }
 }
 return CDialog::PreTranslateMessage(pMsg);
}


give it a try...
