activex开始使用activex


备注

本节概述了activex是什么,以及开发人员可能想要使用它的原因。

它还应该提到activex中的任何大型主题,并链接到相关主题。由于activex的文档是新的,您可能需要创建这些相关主题的初始版本。

Visual Studio C#中的第一个ActiveX创建指南

创作步骤

  1. 以管理员身份启动Visual Studio 2013
  2. 安装Visual Studio扩展Microsoft Visual Studio安装程序项目
  3. 创建一个类库项目(WinFormActivex)
  4. 创建示例窗口表单(MainWindow)
  5. 创建一个新的组件接口(ILauncher)
  6. 创建一个新的安全接口(IObjectSafety)
  7. 创建实现接口并启动窗口的组件控件(Launcher)。
  8. 检查是否所有GUID都是由您生成的
  9. 检查项目是否标记为COM
  10. 使用WinFormActivex的主要输出创建安装项目(LauncherInstaller),其属性为Register = vsdrpCOM
  11. 安装LauncherInstaller
  12. 在资源管理器中运行测试页(test.html)

MainWindow您可以创建一个普通的Form,这里是预生成的。

public partial class MainWindow : Form
{
    public MainWindow()
    {
        InitializeComponent();
    }

    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

    #region Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {
        this.textBox1 = new System.Windows.Forms.TextBox();
        this.textBox2 = new System.Windows.Forms.TextBox();
        this.SuspendLayout();
        //
        // textBox1
        //
        this.textBox1.Location = new System.Drawing.Point(42, 23);
        this.textBox1.Name = "textBox1";
        this.textBox1.Size = new System.Drawing.Size(100, 20);
        this.textBox1.TabIndex = 0;
        //
        // textBox2
        //
        this.textBox2.Location = new System.Drawing.Point(42, 65);
        this.textBox2.Name = "textBox2";
        this.textBox2.Size = new System.Drawing.Size(100, 20);
        this.textBox2.TabIndex = 0;
        //
        // MainWindow
        //
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(284, 261);
        this.Controls.Add(this.textBox2);
        this.Controls.Add(this.textBox1);
        this.Name = "MainWindow";
        this.Text = "MainWindow";
        this.ResumeLayout(false);
        this.PerformLayout();

    }

    private System.Windows.Forms.TextBox textBox1;

ILauncher

using System.Runtime.InteropServices;
namespace WinFormActivex
{
    [ComVisible(true)]
    [InterfaceType(ComInterfaceType.InterfaceIsDual)]
    [Guid("94D26775-05E0-4B9C-BC73-C06FE915CF89")]
    public interface ILauncher
    {
        void ShowWindow();
    }
}
 

IObjectSafety的

[ComImport()]
[Guid("51105418-2E5C-4667-BFD6-50C71C5FD15C")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IObjectSafety

    [PreserveSig()]
    int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions);
    }
 

启动器请在此处生成您的GUID。

test.html请检查您的CLSID是否匹配(启动器)GUID。

<html>
    <head>
        <objectname="activexLauncher" style='display:none' id='activexLauncher' classid='CLSID:D100C392-030A-411C-92B6-4DBE9AC7AA5A' codebase='WinFormActivex'></object>
      <script language="javascript">
        <!-- Load the ActiveX object  -->
        var x = new ActiveXObject("WinFormActivex.Launcher");
        alert(x.GetText());
