>You're welcome. Puns are always appreciated. I think you and Ed Rauh are both seeing it but not letting it sink in. The KB article isn't just about the aliasing of CopyMemory, mempy and RtlCopyMemory it's that if you want to get the memory copying function you basically have to use RtlMOVEMemory (my empasis) which basically performs the same function except in cases of overlapping memory ranges. RtlCopyMemory won't work because it's still refers to an unexported C function. RtlMoveMemory is accessible, however.
Hi Dore,

Yep, that's it RtlMoveMemory (oh happy day!) should do the trick. After a look (via QuickView) inside Kernel32.dll, I noted that there is no RtlCopyMemory, but there is RtlMoveMemory, and that (seems) to work. More later.

Thanks for your persistance (without groans). Geez, if you like puns, you'll be in good company with me, John Koziol and Nancy Folsom. Oh, I'm not "moved" for another pun right now.:-)
