I have been able to call a web service from VFP by passing some parameters to it as follows:

oMyWS.aMethod("un", "pw", 1, CREATEBINARY(FILETOSTR("c:\somefile.ext")))

This works fine when I register the web service via VFP's XML Web Services in the Task Pane Manager.

Now I'm trying to use Microsoft.XMLHTTP Send instead but I'm getting stuck on creating the XML string equivalent for the CREATEBINARY() parameter. Does anyone know how I can do this?

TIA
Mike
