Getting the location of a CStatic object in a dlg.

I've created a modeless dialog box in which I've created several CStatic
box objects. I want to use these boxes as status lights and fill them with
different colors but I can't get the correct location of the boxes.
I've used Class Wizard to create CStatic control member variables for each
box and then called GetClientRect to obtain the right and bottom
coordinates of the box. The problem I have is calculating the top and left
coordinates. I could just subtract the width and height of the boxes but
that places dependancies on the box size and is bound to cause headaches
down the road.
I've tried calling GetWindowRect to get the upper left corner of the dialog
box, and calling GetWindowRect to get the upper left corner of the CStatic
box I'm looking for and then doing the subtraction but it turns out that
I'm offset by the width of the dialog frame and title bar. Again I could
add a compensation factor in here but it places dependencies on the window
layout.
How do I get the location of the box so I can fill it in?
Thanks,
Terry

I'm not sure why you care where they're located. Why don't you just write an
OnCtlColor() handler and paint the control with your solid color?

Try this instead:
CMyDialog :: SomeFunction()
{
...
CRect rect;
m_MyStatic.GetWindowRect( &rect );
m_MyDialog.ScreenToClient( &rect );
...
}
