VB.net or DLL written in C # Wizard button tutorial

First, create a class library

Then delete the default class, of course, you can also keep

Next Add New Item

Then add the COM class

Just a name, remember, not Chinese, not Chinese, not Chinese

You can write code for any function

<ComClass(aabb.ClassId, aabb.InterfaceId, aabb.EventsId)> _
Public Class aabb

#Region "COM GUID"
    ' 这些 GUID 提供此类的 COM 标识 
    ' 及其 COM 接口。若更改它们，则现有的
    ' 客户端将不再能访问此类。
    Public Const ClassId As String = "7a18a092-9f71-45e1-98c0-eb7d7e7c8a30"
    Public Const InterfaceId As String = "d49ba9e0-5d56-439f-b96a-5f83cf8dc324"
    Public Const EventsId As String = "f0e4b02e-2588-4a82-a9c8-69457de2a560"
#End Region

    ' 可创建的 COM 类必须具有一个不带参数的 Public Sub New() 
    ' 否则， 将不会在 
    ' COM 注册表中注册此类，且无法通过
    ' CreateObject 创建此类。
    Public Sub New()
        MyBase.New()
        MsgBox("DLL启动事件")
    End Sub


    Public Function add(a, b)
        Return a + b
    End Function

    Public Function addstring(a As String, b As String) As String
        Return a + b
    End Function

End Class

Then how is registered, registration method and not the same as traditional COM

First, the first mode change it

X86 release into the

Then generated on the line

Next, in the build directory, add a text document, input

taskkill / f / t / im Wizard button Wizard button 2014.exe // end of the process, because Wizard button open, are not registered or inexplicable errors
C: \ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ regasm .exe DLL written tutorials .dll / unregister 'uninstall
C: \ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ regasm.exe DLL written tutorials .dll / codebase' re-registration update
pause 'waiting for input

If the first registration, no debugging, only the following line of code on the line

C: \ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ regasm.exe DLL written tutorials .dll / codebase

taskkill /f /t /im 按键精灵2014.exe
C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe DLL编写教程.dll /unregister
C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe DLL编写教程.dll /codebase
pause

Then save it as bat format
