C#创建ActiveX

来自：http://www.cnblogs.com/homer/archive/2005/01/04/86473.html

创建类库 ActiveX

1、AssemblyInfo中添加引用

using System.Security;//add

添加

[assembly: AllowPartiallyTrustedCallers()] //add

2、创建类或控件（此处创建的用户控件）

将文件中添加如下固定格式的内容。

namespace ActiveX
{
    #region 固定的格式

    [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);
    }
    #endregion 固定的格式



    [Guid("4823975A-ECDE-4947-B673-427E01AADA2D")]//工具-->创建GUID
    [ProgId("ActiveX.AXTest")]//namespace.class
    [ComVisible(true)]

3、Activex类库属性：为COM互操作注册（勾选）

4、重新编译。我们使用 工具—〉OLE/COM对象查看器 查看，

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

1、选择 工具(Tools)-外部工具(External Tools)-添加

2.如图所示在标题中输入“OLE/COM 对象查看器”

   在命令处输入“oleview.exe”，如果提示该命令无效的话请加入具体路径如：C:/Program Files/Microsoft SDKs/Windows/v6.0A/bin/OleView.Exe

3.单击确定。。
