流程概覽
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,命名爲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
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”標籤→勾選“爲COM互操作註冊”。
5.打開Properties裏面的AssemblyInof.cs文件,添加如下代碼:
6.爲控件創建GUID:工具→創建GUID,選5,點擊複製
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:
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
注意接口內容是固定的不要修改!!!也就是說你直接複製粘貼就可以用了,不要管裏面的序列號,跟上面生成的GUID不是一回事。
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:
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!");
}
}
}
注意
[Guid("73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6")]
變成了
[Guid("73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6"), ProgId("ActiveXDemo.UserControl1"), ComVisible(true)]
到目前爲止,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。命名爲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:
四、使用cabarc.exe打包
1.去網上下載cabarc.exe,拷貝到ActiveSetup\Express\DVD-5\DiskImages\DISK1下。
2.在ActiveSetup\Express\DVD-5\DiskImages\DISK1下新建一個install.inf文件,內容如下:
[version]
signature="$CHICAGO$"
AdvancedINF=2.0
[Setup Hooks]
hook1=hook1
[hook1]
run=msiexec.exe /i "%EXTRACT_DIR%\ActiveXSetup.msi" /qn
3.在同目錄下創建一個批處理文件build.bat "cabarc.exe" n test.cab ActiveXSetup.msi install.inf
4.雙擊build.bat ,會自動生成一個test.cab。
五、添加到網頁中測試
1.解決方案ActiveXDemo右鍵-->添加新項目-->Visual
C#-->web-->ASP.NET Web窗體應用程序
2.WebApplication1項目右鍵-->添加新項-->Visual C#-->web-->Web窗體
3.打開WebForm1.aspx,在<div></div>之間添加上面做好的控件,代碼如下
<body>
<form id="form1" runat="server">
<div>
<object id="mytt" classid="clsid:73D3BE6A-E3B3-46F7-AFFE-8673390DA3F6"
codebase="/test.cab"></object>
</div>
</form>
</body>
</html>
clsid就是上面UserControl1.cs中的GUID
將上面的生成的test.cab添加到WebApplication1\bin\目錄下
4.WebForm1.aspx右鍵設爲起始頁,WebApplication1項目右鍵設爲啓動項目
5.選擇IE啓動
可能遇到的問題
IE上顯示的頁面什麼都沒有,是由於ActiveX控件被攔截了。
在Ineternet選項中進行設置,確認“對未標記爲可安全執行腳本的ActiveX控件初始化並執行腳本”項設置爲“啓用”,“下載未簽名的ActiveX控件”項設置爲“提示”
在VS中再來啓動項目,效果如下:
