Hello All,

I am attempting to using API calls to a 3rd party DLL to query their own database.

The function I have found myself using seems fairly simple at first glance...

void CheckDetails (DetailsChecked* details, long* Index)

The problem I have is with the DetailsChecked structure type. The type itself is made up of 70 parameters each being LONG or CHAR* (pointers to the memory address of CHAR datatypes)

An Example would be that the DetailsChecked Structure is made up thus:

(CHAR* String1, LONG LengthOfString1, CHAR* String2, LONG LengthOfString1)

Although with 70 parameters rather than 4.

Can this structure be emulated in VFP 6.0? I have tried declaring an array of 70 elements, I also tried one long character string... until I realised that CHAR* was apointer to the value rather than the value itself. Any ideas?

TIA for any advice or help that can be provided.

Regards,

Ben
