Error: Variable uses an Automation Type not supported in VBScript

I am executing a VBScript function in C++ using Microsoft script control (IScriptControlPtr interface).

VBScript Function:

Function Add1(a,b)
   Add1 = a+b
End Function

I need to pass unsigned long values to the parameters a and b.

So I assigned parameters datatype as VT_UI4. But When executing the function I am getting the error "Variable uses an Automation Type not supported in VBScript".

To my requirement , how to handle unsigned long values?

VBScript only supports signed 2- and 4-byte Integers. So you have to change your arguments to VT_I4, or use type conversion functions like UnsignedToLong and LongToUnsigned. See below for the additional information.
