I defined a method for my WSC component, generated the TLB and looked at
the method signature in OleView. The arguments are always listed as [in]
VARIANT.

First Question:

How do I pass parameters by reference. I tried using the byref parameter in
the WSC function defining the method but the TLB still shows the parameter
as [in] VARIANT.


Second Question:

Within the WSC method, I assign new values to the various parameters. Since
these parameters are defined as [in], the client should not see the updated
values.

This is the behaviour I am seeing when I invoke the WSC method from a VC
client using the IDispatch::Invoke method.

In a VB Client, the client actually sees the updated values from the WSC
method.

Is anyone aware of why this happens and what magic the VB runtime is
performing?
