C/S封装Activex或者OCX插件

1.新建个项目，然后添加类库，添加类库，如图：

2.在Assemblyinfo.cs里添加：

 [assembly: AllowPartiallyTrustedCallers()]   //此处是新增加的

3.添加接口类：IObjectSafety，代码:

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

namespace OCX
{
    [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
    [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
    public interface IObjectSafety
    {
        [PreserveSig]
        int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

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

 

4.在添加一个用户控件，在页面进行布局：

5.在用户控件代码中，添加代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using System.Runtime.InteropServices;

namespace OCX
{
    [Guid("8d7d8518-ca58-4863-b94d-3c616fda7b35")]//此为对外开放，最终被调用的ClassID
    public partial class ActiveX : UserControl, IObjectSafety
    {
        delegate void D(object obj);
        public ActiveX()
        {
            InitializeComponent();
        }

 6.安装部署

      1.添加一个安装部署项目，如图：

  

   2.会出现下面的页面，选择项目输出，如图：

 

 

 3.选择项目为自己的项目名称

4.右键主输出来自XX（活动），出现如下画面，在Register选择 vsdrpCom选项

5.重新生成安装部署程序，在Debug或者Release中找到安装文件，进行安装，安装完毕后，进行调用，classid为程序内部类的GUID，Html如下：

 

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>调用ocx页面</title>
    
        
 <script type="text/javascript">
  var fnTest = function(){
    var x = document.getElementById("x");
     x.Start("这是js中的参数");
  }
 </script>
</head>
<body>
    <form id="form1" runat="server">
 <object id="x" classid="clsid:8d7d8518-ca58-4863-b94d-3c616fda7b35"></object>  

    </form>
</body>
</html>
