ASP classic use a VB.NET 2008 class library DLL

Hi,

I have a website written in ASP which needs to access functions in a VB.NET 2008 class library compiled DLL.

I've been following this tutorial: http://www.justskins.com/forums/asp-accessing-a-vb-net-dll-43525.html but receive the following error when opening my ASP page:

Server object error 'ASP 0177 : 800401f3'
Server.CreateObject Failed
/Default.asp, line 28
800401f3

The only thing I skipped in that tutorial was adding the assembly to the GAC, as I couldn't find gacutil.exe on my server.

Has anyone has success doing this with a VB.net 2008 class library and ASP, or know of any tutorials on the net?

Thanks,

Andrew

as long as you have signed the assembly simply brows to the windows folder and drag|drop this assembly in to assembly folder.

also search for gacutil.exe under C:\WINDOWS\Microsoft.NET\Framework\ folder. It will be in one of the foldels in there.

Thanks vbwizardry, copied gacutil from my development machine to the server, ran it and all worked ok. I didn't know about the c:\windows\assembly folder, my DLL was already in there but uninstalled it and dragged it in again, and it's appearing in there ok. Though website still coming up with the same error.

Have included my default.asp file as a code snippet... I have also been fiddling around with a global.asa file with the DLL's GUID/UUID included... but no success with that either.. have included this file in the code snippet too...
------------------------------------
default.asp
------------------------------------
 
<html>
<head>
</head>
<body>
<%
dim obj
set obj = CreateObject("COMInteropTest.TestClass")
obj.SayHello
set obj = nothing
%>
</body>
</html>
 
 
------------------------------------
global.asa
------------------------------------

Dont forget you have to register your assembly as COM
regasm [assemblyname].dll /tlb:[assemblyname].tlb
look for regasm  in one of the [C:\WINDOWS\Microsoft.NET\Framework\] sub folders
