c# 开发com 问题

Question

 c# 开发activex (已经在系统注册 regasm )在vc 6.0 调用 可以再vc 里面看到控件 但是 不能添加变量 报 the activex control is not registered properly 有谁遇到这样得问题？

Answer 1

声明属性InterfaceType(ComInterfaceType.InterfaceIsDual),ComVisible(true)，以支持register 和 unregister。 6    [
17        Guid("627AD403-FA50-4a08-B875-770520865DD6"),
31        ClassInterface(ClassInterfaceType.None),
40        ComVisible(true)
41    ]
42    public partial class yourclass{...}每次修改之后需要重新注册。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using Microsoft.Win32;
using System.Reflection;
namespace ClassLibrary2
{
    [Guid("7B5F5BA2-0EAE-4351-AE55-B24C63C1ACDD")]
    public interface Iuser
    {
        void msg();
    }    [ProgId("testttttttt")]
    [Guid("6E5DB382-61E6-4b07-9ABC-43EC54FCE810")]
    [ClassInterface(ClassInterfaceType.AutoDispatch)]
    public partial class TestCom : UserControl
    {
        public TestCom()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            this.BackColor = Color.Red;
        }        private void msg()
        {
            MessageBox.Show("this is a test");
        }
    }
}
AssemblyInfo.cs 设置了[assembly: ComVisible(true)] 不能添加变量 vc 6.0 mfc 类向导 添加控件变量 因为vc 中 控件显示ID 必须将该ID 与类型映射 所以添加变量 
现在得情况是控件已经托到窗体了,但是就是无法添加变量

Answer 3

 UserControl ：Iuser 补充一下

          this.button1 = new System.Windows.Forms.Button();
          this.SuspendLayout();
