I have created an interop assembly in C#.
But I couldn't find any way to export helpstrings to the generated typelib
for this assembly.
Which ways have I to do this?

I'm writing a C# app which will populate an Excel spreadsheet.  The app
references Excel using COM.
I have Office 2007 on my machine, but the machine which will be running
the application will have Office 2003.  Therefore, when I added the

I've got a little problem. I used to develop a component with Visual
Studio .NET 2003 (.NET framework 1.1), and registering this assembly
to COM interop with a function only writing keys in the registry
(regedit).

I have a .Net Assembly that is COM enabled (COM-Interop) and so is
instantiated and used in vbscript and jscript.  I install it into the GAC
(during our installation program).  This assembly has dependencies on other
.net assemblies (from another companion product) to run.  These ...

Need some help: I want to call a managed dll (C# code) from a C++
module.
Is there a kind of a 'Reverse-P/Invoke'?
How / what to do?

Is it possible to invoke a .net 2.0 dll (built using VS2005) from a .net 1.1
exe built using vs2003?

I have modified my project from the previous post and am not using

Hi, I'm trying to implement a preview feature in a managed application to
preview files of arbitrary type. Has anyone done this in a managed app? I've
seen at least one suggestion that you can host prevhost on your form, but
I'm not sure this is correct.

Is that really true that in an in-proc C# assembly the Finalize
methods are not called when COM objects are destroyed from the caller?
And if so, is there any solution for this problem? Or the only one is
to define a "Cleanup()" method and tell all users to call it and hope
