It seems to me that you should talk to the programmer who created this DLL to find out exactly what type of parameters his/her DLL expects in C/C++ terms and than we can try to translate it into VFP DECLARE.

As soon as it does the modification, I get the C0000005 error. I have padr() with " " to the lentgh needed and one beyond, trying to stop this error, but it does not work at the moment.
