How to do an ActiveX DLL in VB6 Visual Studio 2005

Open visual studio 2005
create a new project ClassLibrary

on Project->Properties->Build
choose “Register for COM interop”
modify assemblyinfo.cs

[assembly: ComVisible(true)]

Add an interface file (IProvaNet.cs):
using System;
using System.Runtime.InteropServices;

namespace provanet
{
        [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)]
        public interface Iprovanet
        {
            void provaMetodo(string strValue);
            string provaProprieta { get; set; }
        }
}

Add a class file (CprovaNet.cs):

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace provanet
{
    [ClassInterface(ClassInterfaceType.None)]
    public class Cprovanet : Iprovanet
    {
            private string m_prova = “empty”;

            public void provaMetodo(string strValue)
            {
                m_prova = strValue;
            }

            public string provaProprieta
            {
                get { return m_prova; }
                set { m_prova = value; }
            }
    }
}

Test in .NET
Add the class library on reference:
public partial class FormTest : Form
{
        private Centera.CCentera m_Centera;
        public FormTest()
        {
            InitializeComponent();
            m_Centera = new Centera.CCentera();
        }
}

Test in VB6

Add the class library on reference:
Dim m_Centera As centera.CCentera
Private Sub Form_Load()
Set m_Centera = New centera.CCentera
End Sub

Create a “strong name”:

run cmd
cd “C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin”

create a public/private key pair:
sn -k keypair.snk

(If you intend to delay sign an assembly extract the public key:
sn -p keypair.snk public.snk)

on Project->Properties->Signing choose “Sign the assembly” and choose the .snk filename created

Release the Class Library:

compile provanet

set the PATH with the following command:

set PATH=C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin;C:\WINNT\Microsoft.NET\Framework\v2.0.50727;C:\Program Files\Microsoft Visual Studio 8\VC\bin;C:\Program Files\Microsoft Visual Studio 8\Common7\IDE;C:\Program Files\Microsoft Visual Studio 8\VC\vcpackages;%PATH%

use regasm to register (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm.exe)
REGASM provanet.dll

To create the tlb use:

REGASM provanet.dll /tlb:provanet.tlb

Use gacutil to add to Global Assembly Cache if you want to use .dll in a different folder of .exe (C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\gacutil.exe)
Gacutil /i provanet.dll
