Hi Aaron,

acording to the specs I found on the FedEx site, this DLL supports a COM interface as well as a classic C library interface. The following declaration should work. I don't know the name of the DLL, but that should be easy to figure out.

DECLARE LONG FedExAPITransaction in whatever.DLL STRING @host, LONG  port, STRING @sbuf, LONG sbuf_len, long universalTransCode, STRING @rbuf, LONG rbuf_len, LONG @receive_length

When calling a DLL there's no conversion going on. BTW, I think it's a problem with the FedEx object, not VFP. The buffer parameter is incorrectly marked as a BSTR, not as a byte array.
