1. Create a Assembly file using following:
File >> New >> Project >> Class Library >> Name = MyLibCSharp
2. Add a function HelloWorld. Code will look as follows:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace MyLibCsharp
{
[Guid("FE1EB79E-3513-487e-ADFF-2B61C6CB4730")]
[ComVisible(true)]
public class Class1
{
public String HelloWorld(String name)
{
return (“Hellow World; Welcome “ + name);
}
}
}
3. Sign the Assembly (To enable it to be used by multiple Applications):
Go to Project >> MyLibCSharp Properties >> Signing >> Sign the Assembly >> New >> Key.snk
4. Enable for COM Interop:
Go to Project >> MyLibCSharp Properties >> Build >> Output >> Check the “Register for COM interop.
5. Build the Assembly.
6. Add to GAC using “Visual Studio Command Prompt” the assembly is located in DEBUG/RELEASE folder.
gacutil -I MyLibCSharp.dll
7. Execute the following:
Regasm /tlb /codebase MyLibCSharp.dll
8. ASP code:
<%
Dim foo
set foo = Server.CreateObject(“MyLibCSharp.Class1″)
Response.Write (foo.HelloWorld(“test”))
%>
9. To unregister the assembly
Regasm /unregister MyLibCSharp.dll
10. And to remove the same from GAC (Global assembly cache)
Go to
C:\WINDOWS\assembly
find the assembly you want to remove
select it , right click it and select uninstall
Bye

Are you able to debug the dll you create in this example?

Hi,
This is excellent help.
Still a question…Is it necessary to put a assembly in GAC?

This doesn’t appear to work in Vista Business. I get a :
Microsoft VBScript runtime error ‘800a01ad’
ActiveX component can’t create object
depends.exe suggests that this is because gpsvc.dll can’t be loaded, but there appears to be no more information on this anywhere. Any help greatly appreciated.
