• C# 开发Activex


    由于要在网页上显示Tree的结构,开始使用JQuery的Tree,但是当资料量很大时会导致第一次加载很慢。(特别慢,资料量太大了网页一下还反映不过来),于是改用JQuery的FileTree的插件,每层通过ajax的方式到后台获取资料,结果还好,不过当资料量大的时候,频繁的点击页面,反映也会很慢,而且要求Client的配置好些,而这边的site上帝配置都比较低,有的机器会导致无反映的情况。无奈改用Activex的方式吧。对vc不是特别的熟悉,于是选择了C#,因为site上的每个Client都会有.net Framework。OK..开始改写。

    1.创建类库工程

    2.添加一个UserControl,AxTree

    3.定义AxTree Class的属性

    [ProgId("MyTreeActiveX.AxTree")]
    [Guid("A5C532BA-45B2-44c7-ACAE-D526EF9D47B0")]
    [ComVisible(true)]
    [ClassInterface(ClassInterfaceType.AutoDual)]
    [ComSourceInterfaces(typeof(ControlEvents))]

    public partial class AxTree : UserControl, IObjectSafety

    说明:

    ComVisible:是否可以见

    ComSourceInterfaces:该Activex实现的事件的类

    IObjectSafety:继承与该接口,标记安全,否则在生产Activex后,和网页交互还需要对ie进行设定。

    [
          Serializable,
          ComVisible(true)
      ]
       public enum ObjectSafetyOptions
       {
           INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001,
           INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002,
           INTERFACE_USES_DISPEX = 0x00000004,
           INTERFACE_USES_SECURITY_MANAGER = 0x00000008
       }

    [
          ComImport(),
          Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064"),
          InterfaceType(ComInterfaceType.InterfaceIsIUnknown)
      ]
      public interface IObjectSafety
      {
          [PreserveSig]
          long GetInterfaceSafetyOptions(ref Guid iid, out int pdwSupportedOptions, out int pdwEnabledOptions);

          [PreserveSig]
          long SetInterfaceSafetyOptions(ref Guid iid, int dwOptionSetMask, int dwEnabledOptions);
      };

    4.添加方法,属性

    [ComVisible(true)]
           public string Leve1ColorRGB{get..set…}

    方法和属性添加 [ComVisible(true)] 就好

    5.添加Event

    写一个Event的接口,ControlEvent

    [ComVisible(true)]
        [Guid("5F6E5E2D-8C6D-4524-AD44-E8B169D90371")]
        [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
        public interface ControlEvents
        {
            
            [DispId(0x60020001)]
            void OnDial(string callno, string updeppkey);

        }

    在AxTree中定义对应的Event:

    public event ControlEventHandler OnDial;

    6.实现IObjectSafety接口

    #region [IObjectSafety implementation]
            public long GetInterfaceSafetyOptions(ref Guid iid, out int pdwSupportedOptions, out int pdwEnabledOptions)
            {
                pdwSupportedOptions = (int)m_options;
                pdwEnabledOptions = (int)m_options;
                return 0;
            }

            public long SetInterfaceSafetyOptions(ref Guid iid, int dwOptionSetMask, int dwEnabledOptions)
            {
                return 0;
            }
            #endregion

    7.注册和反注册 Atviex

    [ComRegisterFunction()]
           public static void RegisterClass(string key)
           {
               // Strip off HKEY_CLASSES_ROOT\ from the passed key as I don't need it
               StringBuilder sb = new StringBuilder(key);
               sb.Replace(@"HKEY_CLASSES_ROOT\", "");

               // Open the CLSID\{guid} key for write access
               RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);

               // And create the 'Control' key - this allows it to show up in
               // the ActiveX control container
               RegistryKey ctrl = k.CreateSubKey("Control");
               ctrl.Close();

               // Next create the CodeBase entry - needed if not string named and GACced.
               RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
               inprocServer32.SetValue("CodeBase", Assembly.GetExecutingAssembly().CodeBase);
               inprocServer32.Close();

               // Finally close the main key
               k.Close();

           }

           [ComUnregisterFunction()]
           public static void UnregisterClass(string key)
           {
               StringBuilder sb = new StringBuilder(key);
               sb.Replace(@"HKEY_CLASSES_ROOT\", "");

               // Open HKCR\CLSID\{guid} for write access
               RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);

               // Delete the 'Control' key, but don't throw an exception if it does not exist
               k.DeleteSubKey("Control", false);

               // Next open up InprocServer32
               RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);

               // And delete the CodeBase key, again not throwing if missing
               k.DeleteSubKey("CodeBase", false);

               // Finally close the main key
               k.Close();
           }

    8.生成强命名文件。xxx.snk.编译生成…ActvieX的dll写好了。

    安装:

    在该解决方案中添加一个安装项目,选择项目输出->主输出,确认ActiveX的dll文件的属性Register:vsdrpCOM,在调整下其他的属性(文件名..)编译就好。

    cab的安装制作:

    下载cabsdk的工具,微软网站上有的下。

    下载后执行如下:

    C:\cabsdk\BIN\MyTreeActiveX>cabarc.exe n TreeActiveX.cab TreeActiveXSetup.msi My
    TreeActiveX.inf

    Microsoft (R) Cabinet Tool - Version 1.00.0601 (03/18/97)
    Copyright (c) Microsoft Corp 1996-1997. All rights reserved.

    Creating new cabinet 'TreeActiveX.cab' with compression 'MSZIP':
      -- adding TreeActiveXSetup.msi
      -- adding MyTreeActiveX.inf

    Completed successfully

    会生成一个TreeActiveX.cab的文件,网页上就可以使用了。

    对了。inf的定义:

    [version]
    signature="$CHICAGO$"
    AdvancedINF=2.0
    [Setup Hooks]
    hook1=hook1

    [hook1]
    run=msiexec.exe /i "%EXTRACT_DIR%\TreeActiveXSetup.msi" /qn

    网页的写法:

    <object id="ActivexObject" name="ActivexObject" width="100%" height="100%" classid="clsid:A5C532BA-45B2-44c7-ACAE-D526EF9D47B0"></object>

    <script language='javascript'   for='ActivexObject'   event='OnDial(tel,uppkey)'>  

    dosame…

    </script>

    通过以上步骤完成ActiveX的编写,cab的制作和网页的部分。部署好后,会正常使用。

    不过该ActiveX没有签名,所有需要设定一下ie,允许下载为签名的activex才可以正常下载和使用。

    如何对ActiveX进行签名我还不知道,等有时间使用Google大法好好再查查看。
