>>I wasn't sure if this variable was input or output parameter. So far I don't see anything wrong with your code. I'm pretty sure that problem is with DLL you're using. It's strange that it relies on the memory reserved by calling program instead of allocating as much memory as it required. You certanly don't have any control over how VFP manage it's memory.

Hi Leo,

Thanks. I'm sorry I coldn't help you more. BTW, there's Heap allocation class file #9482 in the download section that you could find usefull in working with WIndows API.
