ActiveX插件

C#制作ActiveX插件

首先新建项目--->类库,取名:ActiveXDemo

右键项目属性:应用属性==>程序集信息=>使程序集Com可见,

生成>输出>为com互操作注册

新建接口类取名:IObjectSafety,以下代码可直接用,最好不要修改

复制代码

1 using System;

2 using System.Collections.Generic;

3 using System.Linq;

4 using System.Runtime.InteropServices;

5 using System.Text;

6

7 namespace ActiveXDemo

8 {

9 [ComImport, Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]

10 [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]

11 public interface IObjectSafety

12 {

13 [PreserveSig]

14 int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

15 [PreserveSig()]

16 int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);

17 }

18 }

新建用户控件取名:UserControl1,UserControl1继承自上面新建的接口IObjectSafety,并实现接口(实现接口的方法请复制下面的内容),在类UserControl1添加Guid特性值,利用VS的工具生成guid

复制代码

{

public UserControl1()

{

InitializeComponent();

}

进行简单界面布局:

点击按钮效果见上面代码,还可自己写一个公共方法,我写的是GetGUID(),

生成成功将会生成两个文件:ActiveXDemo.dll和ActiveXDemo.tlb,至此ActiveX浏览器插件制作完成,

以下是如何打包安装ActiveX插件,

我用的InstallShield2010破解版制作安装包

新建InstallScript Msi类型工程

最主要的是在添加文件时候,要把ActiveXDemo.tlb这个文件设为自注册

在生成安装文件时候,可以选择生成适合网络形式的或者单个安装包,在这里我生成了单个安装包,你也可以选择生成网络的

点击生成安装包按钮,生成后如下:

至此,安装包制作完成,我们点击安装后他会自动注册tlb文件.

以下是如何使用ActiveX插件:

新建一个html页面:我取名:TestActiveX.html

内容如下:

注意这里的classid要和你的插件上生成的guid一致才可以

到此,结束,关于用InstallShield制作安装包的详细过程,请自行学习.
