[更新] 我正在更新此答案以在Windows 10 x64和Visual Studio 2017 Community中与Internet Explorer 11一起使用。此答案的先前版本(适用于 Internet Explorer 8,在 Windows 7 x64 和 Visual Studio 2010 中)位于此答案的底部。
创建有效的 Internet Explorer 11 加载项
我正在使用Visual Studio 2017 Community、C#、.Net Framework 4.6.1,因此其中一些步骤对您来说可能略有不同。
您需要以管理员身份打开 Visual Studio来构建解决方案,以便构建后脚本可以注册 BHO(需要注册表访问权限)。
首先创建一个类库。我打电话给我的InternetExplorerExtension。
将这些引用添加到项目中:
- Interop.SHDocVw:COM 选项卡/搜索
"Microsoft Internet Controls"
- Microsoft.mshtml:程序集选项卡/搜索
"Microsoft.mshtml"
注意:不知何故,MSHTML 没有在我的系统中注册,即使我可以在“添加引用”窗口中找到。这在构建时导致错误:
找不到类型库“MSHTML”的包装程序集
可以在http://techninotes.blogspot.com/2016/08/fixing-cannot-find-wrapper-assembly-for.html找到修复程序
或者,您可以运行此批处理脚本:
"%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\Common7\Tools\VsDevCmd.bat"
cd "%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\Common7\IDE\PublicAssemblies"
regasm Microsoft.mshtml.dll
gacutil /i Microsoft.mshtml.dll

最后是一个表单,我们将使用它来配置选项。在这种形式中放置 aTextBox
和 Ok Button
。将按钮的DialogResult设置为Ok。将此代码放在表单代码中:

namespace InternetExplorerExtension
{
public partial class HighlighterOptionsForm : Form
{
public HighlighterOptionsForm()
{
InitializeComponent();
}
public string InputText
{
get { return this.textBox1.Text; }
set { this.textBox1.Text = value; }
}
}
}
在项目属性中,执行以下操作:
- 使用强密钥签署程序集;
- 在 Debug 选项卡中,将Start External Program设置为
C:\Program Files (x86)\Internet Explorer\iexplore.exe
- 在 Debug 选项卡中,将Command Line Arguments设置为
http://msdn.microsoft.com/en-us/library/ms976373.aspx#bho_getintouch
在 Build Events 选项卡中,将Post-build events 命令行设置为:
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\gacutil.exe" /f /i "$(TargetDir)$(TargetFileName)"
"%windir%\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" /注销 "$(TargetDir)$(TargetFileName)"
"%windir%\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" "$(TargetDir)$(TargetFileName)"
注意:即使我的计算机是 x64,我使用了非 x64 的路径gacutil.exe
并且它工作...... x64 特定的一个是:
C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\ x64\ gacutil.exe
64 位 IE需要 64 位编译和 64 位注册的 BHO。虽然我只能使用 32 位 IE11 进行调试,但 32 位注册扩展也可以通过运行 64 位 IE11 来工作。
这个答案似乎有一些关于这个的额外信息:https ://stackoverflow.com/a/23004613/195417
如果需要,可以使用 64bit regasm:
%windir%\Microsoft.NET\Framework 64\ v4.0.30319\RegAsm.exe
这个附加组件的工作原理
我没有改变插件的行为......请查看下面的 IE8 部分进行描述。
## IE8 的上一个答案
伙计……这是一项艰巨的工作!我很好奇如何做到这一点,所以我自己做了。
首先……功劳不全是我的。这是我在这些网站上找到的内容的汇编:
当然,我希望我的答案具有您所要求的功能:
- DOM 遍历找东西;
- 一个显示窗口的按钮(在我的情况下是设置)
- 持久化配置(我将为此使用注册表)
- 最后执行javascript。
我将逐步描述它,我是如何在Windows 7 x64中使用Internet Explorer 8来实现的……请注意,我无法在其他配置中进行测试。希望你能理解 =)
创建有效的 Internet Explorer 8 加载项
我正在使用Visual Studio 2010、C# 4、.Net Framework 4,因此其中一些步骤对您来说可能略有不同。
创建了一个类库。我打电话给我的InternetExplorerExtension。
将这些引用添加到项目中:
注意:这些引用可能位于每台计算机的不同位置。
这是我在 csproj 中的参考部分包含的内容:
<Reference Include="Interop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=90ba9c70f846762e, processorArchitecture=MSIL">

<Reference Include="System.Data" />
<Reference Include="System.Drawing" />
<Reference Include="System.Windows.Forms" />
<Reference Include="System.Xml" />
以与更新的 IE11 文件相同的方式创建文件。
IEAddon.cs
您可以从 IE11 版本中取消注释以下行:
...
// @Eric Stob: Thanks for this hint!
// This was used to prevent this method being executed more than once in IE8... but now it seems to not work anymore.
if (pDisp != this.site)
return;
...

注意:由于我的电脑是 x64 的,所以在我的机器上 gacutil 可执行文件的路径中有一个特定的 x64,可能与你的不同。
64 位 IE需要 64 位编译和 64 位注册的 BHO。使用 64 位 RegAsm.exe(通常位于 C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe)
这个附加组件的工作原理
它遍历所有 DOM 树,替换文本,使用按钮配置,本身带有黄色背景。如果您单击泛黄的文本,它会调用动态插入页面的 javascript 函数。默认词是“浏览器”,所以它匹配了很多!
编辑:更改要突出显示的字符串后,您必须单击 URL 框并按 Enter ... F5 不起作用,我认为这是因为 F5 被视为“导航”,并且需要监听导航事件(也许)。我稍后会尝试解决这个问题。
现在,该走了。我很累。随意提问...可能因为我要去旅行而无法回答... 3天后我回来了,但我会尝试在此期间来这里。
