在网上查了一些资料也实际操作了一下，在此自己再作一次详细记录。
功能：将对机具操作的FK.dll封装成fk.ocx，注册后能在网页上对机器操作。
使用Visual Studio 2010 .NET Framework 2.0（C#）
开发ActiveX步骤：
- 创建一个应用程序解决方案，并添加一个Windows控件库项目
2. 更改“项目属性-应用程序-程序集信息”设置，勾选“使程序集 COM 可见”
3.更改“项目属性-生成”设置，勾选“为 COM Interop 注册”（注意，此处如果实在debug状态下修改的，那在调到release状态下还需要再设置一次）：
4.修改AssemblyInfo.cs文件，添加[assembly: AllowPartiallyTrustedCallers()]项（需要引用System.Security名称空间）：
5.添加一个Windows用户控件名称：DHFkAttendOCX（自已定义，可以将已有的更改名称）
6.为控件类添加GUID，这个编号将用于B/S系统的客户端调用时使用（可以使用 工具-创建GUID 菜单创建一个GUID，再复制）：
7.为了让ActiveX控件获得客户端的信任，控件类还需要实现一个名为“IObjectSafety”的接口，要创建该接口（注意，不能修改该接口的GUID值），IObjectSafety.cs代码如下：
1 using System; 2 using System.Collections.Generic; 3 using System.Text; 4 using System.Runtime.InteropServices; 5 namespace DHFkAttendOCX 6 { 7 [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")] 8 [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)] 9 public interface IObjectSafety 10 { 11 [PreserveSig] 12 int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions); 13 [PreserveSig()] 14 int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions); 15 } 16 }
8.然后在控件类中继承并实现该接口，可以直接复制不用作任何更改：
1 ////IObjectSafety 成员 2 #region IObjectSafety 成员 3 4 private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}"; 5 private const string _IID_IDispatchEx = "{a6ef9860-c720-11d0-9337-00a0c90dcaa9}"; 6 private const string _IID_IPersistStorage = "{0000010A-0000-0000-C000-000000000046}"; 7 private const string _IID_IPersistStream = "{00000109-0000-0000-C000-000000000046}"; 8 private const string _IID_IPersistPropertyBag = "{37D84F60-42CB-11CE-8135-00AA004BB851}"; 9 10 private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001; 11 private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002; 12 private const int S_OK = 0; 13 private const int E_FAIL = unchecked((int)0x80004005); 14 private const int E_NOINTERFACE = unchecked((int)0x80004002); 15 16 private bool _fSafeForScripting = true; 17 private bool _fSafeForInitializing = true; 18 19 public int GetInterfaceSafetyOptions(ref Guid riid, ref int pdwSupportedOptions, ref int pdwEnabledOptions) 20 { 21 int Rslt = E_FAIL; 22 23 string strGUID = riid.ToString("B"); 24 pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA; 25 switch (strGUID) 26 { 27 case _IID_IDispatch: 28 case _IID_IDispatchEx: 29 Rslt = S_OK; 30 pdwEnabledOptions = 0; 31 if (_fSafeForScripting == true) 32 pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER; 33 break; 34 case _IID_IPersistStorage: 35 case _IID_IPersistStream: 36 case _IID_IPersistPropertyBag: 37 Rslt = S_OK; 38 pdwEnabledOptions = 0; 39 if (_fSafeForInitializing == true) 40 pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA; 41 break; 42 default: 43 Rslt = E_NOINTERFACE; 44 break; 45 } 46 47 return Rslt; 48 } 49 50 public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions) 51 { 52 int Rslt = E_FAIL; 53 string strGUID = riid.ToString("B"); 54 switch (strGUID) 55 { 56 case _IID_IDispatch: 57 case _IID_IDispatchEx: 58 if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) && (_fSafeForScripting == true)) 59 Rslt = S_OK; 60 break; 61 case _IID_IPersistStorage: 62 case _IID_IPersistStream: 63 case _IID_IPersistPropertyBag: 64 if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) && (_fSafeForInitializing == true)) 65 Rslt = S_OK; 66 break; 67 default: 68 Rslt = E_NOINTERFACE; 69 break; 70 } 71 72 return Rslt; 73 } 74 75 76 #endregion
9.引用自己想要封装的FK.dll
1 #region 引用dll方法 2 [DllImport("FK.dll")] 3 public static extern int FK_ConnectComm(int nMachineNo, int nComPort, int nBaudRate, 4 string pstrTelNumber, int nWaitDialTime, int nLicense, int nComTimeOut); 5 #endregion
10.封装
1 #region 封装方法 2 [SecurityCritical] 3 public int IDFK_ConnectNet(int nMachineNo, string strIpAddress, int nNetPort, int nTimeOut, int nProtocolType, int nNetPassword, int nLicense) 4 { 5 int result = FK_ConnectNet(nMachineNo, strIpAddress, nNetPort, nTimeOut, nProtocolType, nNetPassword, nLicense); 6 return result; 7 } 8 #endregion
11.打包并发布ActiveX，与普通的Windows Form应用程序的安装部署几乎一样，只有一个地方需要注意，将前面创建的用户控件项目作为主输出项目，并设置其Register属性为vsdrpCOM
12.给应用程序文件夹添加项目输出时，我们将DHFkAttendOCX项目添加进来，在项目中选择DHFkAttendOCX控件项目
13.将FK.dll和其它引用的dll都一并作为文件添加
14.在系统文件夹system32文件夹中将msiexec.exe（卸载控件时用到）地址找到也添加至上面文件夹
15.在“用户的程序菜单”中，新建文件夹后加入主程序与msiexec.exe快捷方式
16.点击安装项目工程，在属性中将ProductCode复制，点击msiexec.exe快捷方式，在属性Arguments中 加入"/x+一个空隔+ProductCode"
17.生成项目，打包文件就生成了，打开..\Debug看到生成了2个文件，一个是xx.exe,一个是xx.msi，执行exe安装到系统。
18.安装成功后， 在页面中添加<object id="csocx" classid="clsid:FE7EC23B-78A6-45B9-B61E-945970D963B6"></object>
"FE7EC23B-78A6-45B9-B61E-945970D963B6"为第6步生成的GUID
19.页面中js中引用
<script language="javascript" type="text/javascript">
//操作
function OnOpearOnMachion(opearValue) {
var ocxKq = document.getElementById("csocx");
var bolResult = ocxKq.IDFK_ConnectNet(1, "192.168.0.123", 5005, 3000, 0, 0, 123);
}
</script>
20.大功造成。

22.要注意的是，浏览器要设置以下控件才能正常运行
安装所需要的控件后：
打开IE浏览器，在菜单栏点击“工具”—“Internet选项”—“安全”选项卡。
1. 点击“受信任站点”
2.然后点击“站点”弹出如下图片：
3.按照上图填写内容后，点击“添加”然后点“确定”.
4. 设置自定义安全级别(internet本地、受信任站点均需要)
5.点击“自定义级别”，弹出如下图片，选择“安全级 – 低” 然后将组件全部“启用”：
