最近需要在Web上使用WinFrom程式，所以要用到Activex技術將WinFrom程式變成外掛程式在Web運行
一、建立使用者控制項
1.1 建立使用者控制項項目
1.2 在介面上拉一個label，Text賦值為“HelloWorld”
1.3 加上guid
using System;using System.Windows.Forms;using System.Runtime.InteropServices;using System.Diagnostics;namespace HelloWorld{ [Guid("ce85468b-7742-4279-b081-2eca51a2afbc")] public partial class Demo : UserControl, IObjectSafety { public Demo() { InitializeComponent(); } }}
二. 建立安裝項目
2.1 命名：HelloWorld.Setup
2.2 將HelloWorld.dll加進來
2.3 雙擊HelloWorld.Setup.msi安裝即可
三、 建立Index.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head> <title></title> <script type="text/javascript" src="jquery-1.8.2.min.js"></script></head><body> <div> <object id="demo" classid="clsid:ce85468b-7742-4279-b081-2eca51a2afbc" width="300" height="200" /> </div></body></html>
3.1 注意紅色部分，這個clsid即是使用者控制項的guid
3.2 運行Index.html
四、添加自訂方法和按鈕功能4.1 上邊的功能太簡單，我們稍微深入一點，添加一個方法給js代碼調用，在Demo.cs中加上下邊代碼
public string SayHello() { return "Hello World"; }
4.2 新增一個按鈕，開啟文字框
4.3 按鈕單擊事件
private void button1_Click(object sender, EventArgs e) { Process.Start("notepad.exe"); }
4.4 再重新編譯運行程式，然後Index.html，雙擊按鈕
4.5 修改Index.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head> <title></title> <script type="text/javascript" src="jquery-1.8.2.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#btn1").click(function () { var demo = document.getElementById("demo"); console.log(demo.SayHello()); }); }); </script></head><body> <div> <input id="btn1" type="button" value="調用後台SayHello方法" /> <object id="demo" classid="clsid:ce85468b-7742-4279-b081-2eca51a2afbc" width="300" height="200" /> </div></body></html>
4.6 點擊“調用後台SayHello方法”按鈕
OK，暫時就到這裡！
