C# 制作ActiveX控件並添加到網頁
1.創建ActiveX控件——按鈕
2.定義一個接口，並在控件中實現
3.部署安裝
4.CAB打包
5.添加到網頁中進行測試
一. 創建ActiveX控件——按鈕
1.新建一個Window窗體控件庫項目，命名為ActiveXDemo.
2.在自動生成的UserControl1頁面上添加一個button
3.點擊事件裏我們只彈出一個MesageBox
[csharp] view plain copy
- private void button1_Click(object sender, EventArgs e)
- {
- MessageBox.Show("Active is working now!");
- }
4.在右邊解決方案資源管理器的ActiveXDemo項目上右鍵→屬性→應用程序→程序集信息→使程序集COM可見（M）。再切換到“生成”標簽→勾選“為COM互操作註冊”。
5.打開Properties裏面的AssemblyInof.cs文件，添加如下代碼：
6.為控件創建GUID：工具→創建GUID，選5，點擊復制
7.打開UserControl1.cs，在public partial class UserControl1 : UserControl上面粘貼上一步生成的GUID，並添加using System.Runtime.InteropServices;
代碼如下：
[csharp] view plain copy
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- using System.Drawing;
- using System.Data;
- using System.Linq;
- using System.Text;
- using System.Threading.Tasks;
- using System.Windows.Forms;
- using System.Runtime.InteropServices;
- namespace ActiveXDemo
- {
- [Guid("73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6")]
- public partial class UserControl1: UserControl
- {
- public UserControl1()
- {
- InitializeComponent();
- }
- private void button1_Click(object sender, EventArgs e)
- {
- MessageBox.Show("ActiveX is working now!");
- }
- }
- }
二、定義一個接口，並在控件中實現
創建一個IObjectSafety接口，讓ActiveX 控件獲取客戶端的信任。
1.右鍵ActiveXDemo項目—>添加—>新建項→Visual C#項→接口
註意接口內容是固定的不要修改！！！也就是說你直接復制粘貼就可以用了，不要管裏面的序列號，跟上面生成的GUID不是一回事。
[csharp] view plain copy
- using System;
- using System.Runtime.InteropServices;
- namespace ActiveXDemo
- {
- [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);
- }
- }
2.在UserControl1控件的後臺代碼UserControl1.cs中實現這個接口，代碼如下：
[csharp] view plain copy
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- using System.Drawing;
- using System.Data;
- using System.Linq;
- using System.Text;
- using System.Threading.Tasks;
- using System.Windows.Forms;
- using System.Runtime.InteropServices;
- namespace ActiveXDemo
- {
- [Guid("73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6"), ProgId("ActiveXDemo.UserControl1"), ComVisible(true)]
- public partial class UserControl1 : UserControl, IObjectSafety
- {
- #region IObjectSafety 成員 格式固定
- private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";
- private const string _IID_IDispatchEx = "{a6ef9860-c720-11d0-9337-00a0c90dcaa9}";
- private const string _IID_IPersistStorage = "{0000010A-0000-0000-C000-000000000046}";
- private const string _IID_IPersistStream = "{00000109-0000-0000-C000-000000000046}";
- private const string _IID_IPersistPropertyBag = "{37D84F60-42CB-11CE-8135-00AA004BB851}";
- private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001;
- private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002;
- private const int S_OK = 0;
- private const int E_FAIL = unchecked((int)0x80004005);
- private const int E_NOINTERFACE = unchecked((int)0x80004002);
- private bool _fSafeForScripting = true;
- private bool _fSafeForInitializing = true;
- public int GetInterfaceSafetyOptions(ref Guid riid, ref int pdwSupportedOptions, ref int pdwEnabledOptions)
- {
- int Rslt = E_FAIL;
- string strGUID = riid.ToString("B");
- pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
- switch (strGUID)
- {
- case _IID_IDispatch:
- case _IID_IDispatchEx:
- Rslt = S_OK;
- pdwEnabledOptions = 0;
- if (_fSafeForScripting == true)
- pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
- break;
- case _IID_IPersistStorage:
- case _IID_IPersistStream:
- case _IID_IPersistPropertyBag:
- Rslt = S_OK;
- pdwEnabledOptions = 0;
- if (_fSafeForInitializing == true)
- pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
- break;
- default:
- Rslt = E_NOINTERFACE;
- break;
- }
- return Rslt;
- }
- public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)
- {
- int Rslt = E_FAIL;
- string strGUID = riid.ToString("B");
- switch (strGUID)
- {
- case _IID_IDispatch:
- case _IID_IDispatchEx:
- if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) && (_fSafeForScripting == true))
- Rslt = S_OK;
- break;
- case _IID_IPersistStorage:
- case _IID_IPersistStream:
- case _IID_IPersistPropertyBag:
- if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) && (_fSafeForInitializing == true))
- Rslt = S_OK;
- break;
- default:
- Rslt = E_NOINTERFACE;
- break;
- }
- return Rslt;
- }
- #endregion
- public UserControl1()
- {
- InitializeComponent();
- }
- private void button1_Click(object sender, EventArgs e)
- {
- MessageBox.Show("ActiveX is working now!");
- }
- }
- }
註意
- [Guid("73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6")]
變成了
[csharp] view plain copy
- [Guid("73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6"), ProgId("ActiveXDemo.UserControl1"), ComVisible(true)]
可能發生的問題
到目前為止，ActiveXDemo項目完工了，ActiveXDemo項目右鍵-->生成。
這個時候，我這邊出現了一個錯誤：
錯誤 1 無法註銷程序集“D:\learnActiveX\ActiveXDemo\ActiveXDemo\bin\Debug\ActiveXDemo.dll”- 拒絕訪問。請確保您正在以管理員身份運行應用程序。不允許所請求的註冊表訪問權。ActiveXDemo
最後發現用管理員身份運行VS2012，然後打開ActiveXDemo項目，再生成，就不會報錯了。
三、打包部署
1.解決方案ActiveXDemo右鍵-->添加新項目-->其他項目類型-->安裝和部署。如果你沒有安裝過這個，請先安裝。命名為ActiveSetup
2.選擇application information：基本配置，自定義填寫
3.接下來先把Application Files,點擊MyCompany下的第一個節點可以自己重命名
4.點擊 Add Project OutPuts，選擇主輸出點ok
5.ActiveSetup項目右鍵，生成。在ActiveSetup\Express\DVD-5\DiskImages\DISK1文件夾下有如下文件：
一個exe一個mis我們只用mis的
還要一個cabarc.exe這個我會在下載裏給大家提供
cabarc.exe：微軟提供的cab打包工具
ActiveXSetup.msi： 項目生成的部署安裝文件 install.inf ： 需要跟ActiveXSetup.msi打包在一起的文件 build.bat： 打包的批處理命令install.inf
[version] signature="$CHICAGO$" AdvancedINF=2.0 [Setup Hooks] hook1=hook1 [hook1] run=msiexec.exe /i "%EXTRACT_DIR%\ActiveXSetup.msi" /qn
build.bat
"cabarc.exe" n test.cab ActiveXSetup.msi install.inf
運行一下bat就可以生成一個
cab
我們隨便建一個webfrom網站
在debug下邊建一下dll文件夾
把test.cab放到文件夾裏
