Jose,

You might be able to:

lcTiff = space(n) && where n is big enough
CallDLL( @lcTiff )

I'm not exactly sure what you can do with a TIFF memory image in a VFP string.

>We are trying to use a function that opens an image in a TIFF format and stores it in memory. We need to allocate memory for this and create a pointer to this memory buffer. How can we manage these operations in VFP?
