最近有这样一个需求，需要在网页上面启动客户端的软件，软件之间的通信、调用，单单依靠HTML是无法实现了，因此必须借用Activex来实现。由于本 人主要擅长C#，自然本文给出了用C#实现的范例，本文的预期效果是有一定Winform基础的人可都轻松读懂本文。
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace EasyActivex
{
[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);
}
}
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;
namespace EasyActivex
{
//这个Guid，网页调用的时候用到，Mark
[Guid("685F0A47-944D-4145-BF4E-76A02A422B02")]
//这里要实现IObjectSafety接口
public partial class EUserControl : UserControl, IObjectSafety
{
public EUserControl()
{
InitializeComponent();
}
#region IObjectSafety 接口成员实现（直接拷贝即可）
private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";

switch (strGUID)
{
case _IID_IDispatch:

break;

break;

return Rslt;
}
public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)
{

string strGUID = riid.ToString("B");
switch (strGUID)
{
case _IID_IDispatch:

if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) && (_fSafeForScripting == true))
Rslt = S_OK;
break;
case _IID_IPersistStorage:
case _IID_IPersistStream:

if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) && (_fSafeForInitializing == true))
Rslt = S_OK;
break;
default:
Rslt = E_NOINTERFACE;
break;
}
return Rslt;
}
#endregion
/// <summary>
/// 打开记事本
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnOpenNote_Click(object sender, EventArgs e)
{
System.Diagnostics.Process.Start("notepad.exe");
}
}
}
小提示：EUserControl代码的Guid可以用VS附带的Guid生成工具生成：
//用户添加 [assembly: AllowPartiallyTrustedCallers()]
[version] signature="$CHICAGO$" AdvancedINF=2.0 [Setup Hooks] hook1=hook1 [hook1] run=msiexec.exe /i "%EXTRACT_DIR%\EasySetup.msi" /qn
2） build.bat制作。新建txt文件，加入以下内容，将文件名重新命名build.bat即可。其中EasyActivex.cab是生成目标cab 的名称；install.inf是第一步生成的文件名，而EasySetup.msi是需要打包的安装程序名；第二条ping命令仅仅是让批处理不要那么 快退出，起到更利于观察生成结果的作用。
"cabarc.exe" -s 6144 n EasyActivex.cab install.inf EasySetup.msi ping -n 20 127.0.0.1 >nul
<object id="csharpActiveX" codebase="Activex/EasyActivex.cab" classid="clsid:685F0A47-944D-4145-BF4E-76A02A422B02"></object>
运行效果如下：
点击即可在网页中打开记事本了。
