ComboBox cut off

Environment: VC++4.1, MFC, Windows NT 4.0

I have a drop-list combo box (styles: visible, tabstop, vertical 
scroll, not owner drawn) on a form, immediately above an edit box.

The size of the drop down box is being limited by the edit box 
beneath it.  There are members to set the width of the drop down, but 
not the height.  

Here's my question:  How can I control the vertical size of the drop 
down for a Combo Box?  I need it to overlap an edit box immediately
beneath it.   Does the Combo create a child window
every time it needs to display the drop down?

Thanks

1. Did you set the size of the dropdown in the Resource Editor?

[Moderator's note: For all of you asking "How do I do this?", it's
easy.  You click the dropdown button (that little button on the
right of the combo box) and the resize handles change to size the
dropdown.  This is documented, but many people miss it.]

2. It's my understanding that the drop down portion is a child window. this
     can cause problems if you move the dialog when the drop down is
     active.

No, it isn't.  The size of a combo box with it's drop down is the size
you create for the window.  The size of the edit control is based on
the font you're using in the box.

Create() sets the height and width, initially. 
MoveWindow() and SetWindowPos() and probably a couple of other functions
set the width and the heigt after the fact.

Then size the combo box so that it covers the edit control your talking about.

Yep.  Spy++ would show you as much.
