Hi there.  I have a COM DLL that I have converted into an interop assembly
via the tlbimp.exe tool.  One function that I am trying to use now in C# has

I am trying to access a .NET class written in c# from a VB6 application.  I

change this function, and I want to call it from C++. The IDL
looks like this:

Can anybody tell me how I use the MarshalAs-Attribute to mark a
parameter as a VARIANT which contains a SAFEARRAY?
Or can I rebuild a structure VARIANT which I can use to transport a
SAFEARRAY?

I am having problems getting a component that was written in VB6 to work
inside of vb.net.  It is a queued component.  Can someone send me some
sample code that would work in this instance?  Here are some questions:
1.  Should GetObject still work inside of vb.net?  If so, what ...
