I need to dynamically highlight / un-highlight CEdit controls, preferrably
by adding / removing the borders.
I have tried CWnd::ModifyStyle and ModifyStyleEx with no effect.

Please tell me how to add remove borders to/from a CEdit control without
re-creating it.

thanks much

Chuck

Certain window data is cached, so changes you make using SetWindowLong
will not take effect until you call the SetWindowPos function.
Specifically, if you change any of the frame styles, you must call
SetWindowPos with the SWP_FRAMECHANGED flag for the cache to be
updated properly.

Make sure you specify SWP_DRAWFRAME when you use ModifyStyle:

CEdit * pEd = static_cast<CEdit *>(GetDlgItem( IDC_EDIT1 ) );    
pEd->ModifyStyleEx( WS_EX_CLIENTEDGE, 0, SWP_DRAWFRAME );

It depends what styles you're trying to change - many controls allow
you to change their style at run-time, but don't take any notice of
the changes - they only take effect when the control is created.
