开发环境是Vs 2012 Framework 4.0
源码和制作工具在文章最下边
一. ActiveX控件Demo
新建一个Window窗体控件库项目
在自动生成的UserControl1页面上添加一个button
点击事件里我们只弹出一个MesageBox
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("Click!!!!");
}
IE怎么知道一个插件是脚本安全的？它是通过以下两个办法。一是查询ActiveX组件是否实现了IObjectSafety接口，并且
返回脚本安全；二是查询ActiveX组件是否在注册表的Component Category Manager里表明自己实现了
CATID_SafeForInitializing和CATID_SafeForScripting。
这里我们只说第一种实现IObjectSafety接口
接口格式是固定的不要修改
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);
}
}
在UserControl1控件的后台代码我们要实现这个接口
看一下代码
using System;
using System.Windows.Forms; namespace ActiveXDemo
{
using System.Runtime.InteropServices; [Guid("6169E98E-DA08-4E87-81B6-EE3A5034C0E2"), ProgId("ActiveXDemo.UserControl1"), ComVisible(true)]
public partial class UserControl1: UserControl,IObjectSafety
{ #region IObjectSafety 成员 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_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 = ;
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 = ;
if (_fSafeForScripting == true)
pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
break;
case _IID_IPersistStorage:
case _IID_IPersistStream:
case _IID_IPersistPropertyBag:
Rslt = S_OK;
pdwEnabledOptions = ;
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("Click!!!!");
}
}
}
这里要做一下修改
[Guid("6169E98E-DA08-4E87-81B6-EE3A5034C0E2"), ProgId("ActiveXDemo.UserControl1"), ComVisible(true)]
这个guid是我自己生成的还有ProgId里的ActiveXDemo.UserControl1是我自己工程里的，修改成你自己的
gui生成是在 菜单 工具 下边
打开项目属性，
在应用程序里 点击程序集信息 勾选 使程序集COM可见
在生成里边，勾选 为Com互操作注册
做到这里我们的ActiveX控件就做完了接下来我们把它发布
先是把它打包
Vs2012 打包我之前有些不同
新项目——其他项目 安装和部署
选择application information：基本配置，自定义填写
接下来先把Application Files,点击MyCompany下的第一个节点可以自己重命名
点击 Add Project OutPuts
选择主输出点ok
因为我们的demo就一个dll所以不用再有别的操作
如果想修改一下安装的窗体可以在Installation Interview里设置
在Express\DVD-5\DiskImages\DISK1文件夹下就是我们的安装软件了
一个exe一个mis我们只用mis的
还要一个cabarc.exe这个我会在下载里给大家提供
cabarc.exe：微软提供的cab打包工具
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
运行一下bat就可以生成一个
cab
我们随便建一个webfrom网站
在debug下边建一下dll文件夹
把test.cab放到文件夹里
在首页上这样写
<body>
<form id="form1" runat="server">
<div>
<object id="mytt" classid="clsid:6169E98E-DA08-4E87-81B6-EE3A5034C0E2"
codebase="/DLL/test.cab"></object>
</div>
</form>
</body>
</html>
这个Classid就是我们在UserControl1.cs的Guid里的序列号
看一下效果吧
