parameter doesn't return value to ASP or VB
You can use get_Properties to return exactly one value from C++ code to
VBScript (let the Wizard generate the code). If you need more than one
value returned, as Rahul says, define your parameters as [out] VARIANT *.
You have to work just a bit harder making sure you assign the proper type.
