Try to use normal words instead of abbreviations... maybe your posts become more readable and easier to understand.

If you have a problem, we can try to help. That tutorial is pretty good, I've read it myself, it covers everything you'd need to know to do it.

Represent?! lol :D

when i make the API call:
CopyMemory ByVal VarPtrArray(pic), VarPtrArray(sa), 4
i get an error because sa is not an array
and VarPtrArray returns the memory address of an ARRAY..

If thats the case, I'd suggest making 'sa' an array...

Sorry but thats as much help as I can give with the info you've given me. Could you elaborate a bit? :D

well i get errors when making 'sa' an array also.. i dont know how to further explain my problem, i dont fully understand the use of 'sa'. probably the most helpful thing would be some sample code.. if u dont mind
