ByRef Variable Passing from ASP to COM
Hello,
<IN> variables may be correctly typed in your component but must be declared
ByVal in the component.
There is no <OUT> available to VB.
<IN/OUT> must be declared as variant if it is used in ASP. ASP only uses
variant. I think arrays must also be declared variant even if they are only
<IN>.
