Cursor shape on overlapped child controls

Hello,

        Env: Win NT 3.51/VC++ 2.2

        I have grid like layout in the view where there are windows derived
from CEdit. My application requires, when the user clicks on a edit control
to display a value list(which I am doing with combo box) displayed at left
top corner of the view and the window for combo box spans some edit controls
too. When the mouse is moved to combo box to select an item, the cursor
changes to hair cursor instead of Arrow due to edit control beneath it. This
causes lot of frustration for the end users.

         I tried changing the parent window to mainframe but I do not get
messages from combo box which I am currently handling in view class.

        Am I missing something. Thanks in advance for the help.

Just check for WM_NCHITTEST over the combo box. If it's over combo box eat
the WM_SETCUROSR message.

I'm new to the MFC and VCPP, so all I can offer is my best guess based on 
intercepting the WM_SETCURSOR message under Win3.x.  I'd try overriding the 
CWnd::OnSetCursor class, include a test for your ComboBox ID, and change the 
cursor to an arrow if true.

If nothing else, ::OnSetCursor should be the right method for the override; I 
don't have enough experience with the MFC to guarantee that CWnd is the right 
class, but at least it's somewhere to start from.
