Hi Puri,
This is purely a guess, but my inclination would be to check to make sure that I was passing the parameters to the first DLL correctly. For example, many DLLs won't squawk a bit if you pass a string by value when it requires that you pass it by reference, they simply won't work properly.
If this isn't it, if you'd care to supply some sample code (including both the VFP and C function declaraions), then perhaps I or someone else might be able to help.
