Getting handle of edit controls

Hi,

I'm working on a database application with Visual C++ & MFC 4.0 & 
ODBC.
I have a CRecordView-derived window with several edit boxes to 
display/edit current record values.
How can I retrieve the handle (or a CWnd*) of the edit box that has 
the input focus?
I tried

 CEdit * ed = dynamic_cast( GetFocus( ) );

but it doesn't work.

Any clues?

You can't use dynamic_cast becuase the temporary window created by MFC is 
always a CWnd* and not a pointer to any other particular type of object. So, 
the dynamic_cast you wrote will always fail.

You can retrieve the handle by calling ::GetFocus() instead of 
CWnd::GetFocus().
You can retrieve the CWnd* by calling CWnd::GetFocus().
