Dan,

I have no idea. I'nm sure there is something in the VC++ language that will do that but I haven't got a clue if and how VFP makes use of that. I wouldn't suggest muckig around with the memory heap of a runing application from outside ot that application anyway even if I knew which API function would do it. Especially with the fancy pancy stuff that VFP does with memory.
