I do believe you are on the right track. The StrConv technique would allow me to return a string to VB.net. The ASP/VB app does not need to decode the string but subsequent processing of the table by a VFP app will need to decrypt. I think this will work nicely.

I suppose I could have encrypted the string in the VB app but I was not sure the result could be decrypted in the VFP app at a later date.

Thanks

>>Thanks for the reply Alex. The VFP COM object provides a function which returns an encrypted string (using Craig's FLL) back to a VB.Net (2.0) program. To accomplish this feat the VFP app must declare a return data type to be compatible with .Net.
