Hi Ed

The only message is a VFP message saying Declare DLL call caused an excption.

The don't think the DLL requires registration, I can make other calls to it OK, but the file upload is causing problems.

I have tried removing the path but it still causes an error.

Using the NumToLong() function from my ClsHeap library (available for download in the download section as Heap Allocation Class), I'd construct it as:

cTaggerLogFileStruc = PADR(ALLTRIM(cUploadFileName),13,chr(0)) + NumToLong(LEN(cDataBlock))
