Hi

I have created a .dll in vb.net, however i am trying to call it from my classic asp page. First is this possible? I think there shouldn't be any conflict with this. Second, I already registered my .dll with regasm.exe . Then I tried running my asp page and it displayed it error:

ASP file or assembly name "myClass", or one of its dependencies was not found.

This error occurs at the line where i set my variable = to Server.CreateObject("MyCLass.Class1"). Any ideas?

Thanks,

Kyle

1. It is possible, but only if you expose the VB.NET DLL as a COM or COM+ object and install it into the GAC. Classic ASP is a scripting technology and it can only do late-binding to call into COM DLLS. The CLR always locates a DLL using fusion, and NOT the COM registry (although it does have to be registered for the benefit of ASP). This means it will look in the application directory and the bin subfolder, HOWEVER, you don't have an application directory because you're calling the DLL as a COM object, so it must be loaded in the GAC in order to be found. Do some web searches to learn how to deploy the DLL to the GAC (which requires giving it a strong name first).
2. This forum is for the book "ASP.NET Website Programming Prob-Design-Solution", so this question is off topic here.

Thanks,

But what is a GAC ?

The GAC is the Global Assembly Cache. You really need to read an intro book on .NET. I can't teach a complex subject like that in a message forum. The problem is that a lot of other questions flow from the answer:

1) Whay do we need a GAC?
2) What problems does it solve?
3) What problems does it create?
4) What is fusion and why does it matter?
5) What are alternatives?
6) How do I deploy assemblies to the GAC?
7) What is a strong name?
8) How do I give a strong name to my assemblies?

etc.

And, as I said before, this would be off-topic in this forum anyway.
