I've had a problem similiar to this and I resolved it by doing this:=20

Subclass the controls you insert in your dialog ( create your own class =
derived from CEdit for example ) and catch the Tabs within your control =
by catching WM_KEYDOWN messages and doing the following bit of code:

void CMyEditCtl::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
	if ( (nChar =3D=3D VK_TAB) && (GetKeyState(VK_SHIFT) < 0) ) //Shift-Tab =
was pressed
   	{
      		((CDialog*)GetOwner())->PrevDlgCtrl();
   	}
   	else if (nChar =3D=3D VK_TAB)  // Tab was pressed
   	{
      		((CDialog*)GetOwner())->NextDlgCtrl();
      }=20
}

This maybe of some help.  My problem was with a OLE Control, inserted =
into a container.  The control fires off a modeless dialog.  The tab =
messages get sucked up by the container of the control, not by the =
control or its modeless dialog.
