>>Basically, you cannot use arrays to pass them to DLL functions. When you need an array as param for a DLL function, it's supposed that the array is stored in a contigous memory area. Can you be sure that your VFP array is stored contigous in memory? No. And it's not. This is why it doesn't work in the way you want to do it and this is why you need to use a string instead of an array.

Always pass strings by reference to DLL functions.
