Hi!

1. Try nodefault can help in MouseDown event. I doubt it will help in MouseUp event because mouseDown fire the header movement or resizing process that is finished by Click event always.

For what do you need it? If you want to prevent column movement or resizing, just set column properties Moveable and Resizable to .F.

2. You can use COM object in VFP, but beware about data types for functions - they all should be variant. You cannot update VFP data from COM object, you can use C++ functions for some and complex calculations that require better speed. There is VFP SDK for C++ - you can write the FLL library for VFP application that can use VFP internal functions to access data and otehr things from VFP. You can read abot this more at the site of the developers of the FOCUS.FLL library (http://www.fastwrite.com/PRODUCTS/FOCUS/FLL/index.cfm?CFID=200066&CFTOKEN=61419824). They also give guidelines and additional tools for that.

HTH.
