创建接口 IObjectSafety

注意

[Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
public interface IObjectSafety

这个 guid是死的,所有地方都一样

    [Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    public interface IObjectSafety
    {
        // methods
        void GetInterfacceSafyOptions(
         System.Int32 riid,
         out System.Int32 pdwSupportedOptions,
         out System.Int32 pdwEnabledOptions);
        void SetInterfaceSafetyOptions(
         System.Int32 riid,
         System.Int32 dwOptionsSetMask,
         System.Int32 dwEnabledOptions);
    }

    public abstract class ActiveXControl : UserControl,IObjectSafety
    {
        const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 1;
        const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 2;

        public void GetInterfacceSafyOptions(System.Int32 riid, out System.Int32 pdwSupportedOptions, out System.Int32 pdwEnabledOptions)
        {
            pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
            pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
        }
        public void SetInterfaceSafetyOptions(System.Int32 riid, System.Int32 dwOptionsSetMask, System.Int32 dwEnabledOptions)
        {

        }
    }

创建用户控件类

 [Guid("bcd0a305-5e3c-44d8-b6ff-c2ab256576ad")]
    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("这是一个com组件ActiveXControl");
        }
    }
