Ale*_*lex 204 c# c++ internet-explorer atl browser-extension
这里有没有人有开发可以分享知识的IE扩展的经验？这将包括代码示例,或指向良好代码的链接,或流程文档或任何内容.
我真的很想这样做,但我正在用糟糕的文档,糟糕的代码/示例代码/缺乏它来打造巨大的墙.您可以提供的任何帮助/资源将不胜感激.
具体来说,我想从如何从IE扩展中访问/操作DOM开始.
编辑,更多细节:
理想情况下,我想种植一个工具栏按钮,当单击该按钮时,会弹出一个菜单,其中包含指向外部站点的链接.我还想根据某些条件访问DOM并在页面上植入JavaScript.
在IE扩展中保留信息的最佳方法是什么？在Firefox/Chrome /大多数现代浏览器中,您使用window.localStorage,但显然使用IE8/IE7,这不是一个选项.也许是SQLite DB等？可以假设.NET 4.0将安装在用户的计算机上吗？
我不想使用Spice IE,因为我想构建一个与IE9兼容的.我也在这个问题上添加了C++标签,因为如果用C++构建一个更好,我可以做到.

[更新]我正在更新此答案以使用Internet Explorer 11,在Windows 10 x64中使用Visual Studio 2017社区.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.
我使用的Visual Studio 2017年的社区,C# ,.Net框架4.6.1,所以某些步骤可能是你稍有不同.
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).
Start by creating a class library. I called mine InternetExplorerExtension.
Add these COM references to the project:
Note: Somehow MSHTML was not registered in my system, even though I could find in in the Add Reference window. This caused an error while building:
Cannot find wrapper assembly for type library "MSHTML"
The fix can be found at http://techninotes.blogspot.com/2016/08/fixing-cannot-find-wrapper-assembly-for.html Or, you can run this batch script:
"%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,我们将用它来配置选项.在这个表格中放置一个"Microsoft Internet Controls"和一个Ok "Microsoft.mshtml".将按钮的DialogResult设置为Ok.将此代码放在表单代码中:
using System.Windows.Forms;
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:
TextBoxButton在"构建事件"选项卡中,将"构建后事件"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" /unregister "$(TargetDir)$(TargetFileName)" "%windir%\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" "$(TargetDir)$(TargetFileName)"
注意:即使我的计算机是x64,我也使用了非x64的路径C:\Program Files (x86)\Internet Explorer\iexplore.exe并且它有效... x64特有的是:
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位注册扩展也可以运行64位IE11.
这个答案似乎有一些额外的信息:https://stackoverflow.com/a/23004613/195417
如果需要,可以使用64位regasm:
%windir%\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe
这个附加组件的工作原理
我没有改变附加组件的行为...看看下面的IE8部分描述.
男人......这已经做了很多工作!我很好奇如何做到这一点,我自己做了.
首先......信誉并不全是我的.这是我在这些网站上找到的内容的汇编:
And of course, I wanted my answer to have the features you asked:
I will describe it step by step, how I managed to do it working with Internet Explorer 8, in Windows 7 x64... note that I could not test in other configurations. Hope you understand =)
I am using Visual Studio 2010, C# 4, .Net Framework 4, so some of these steps might be slightly different for you.
Created a class library. I called mine InternetExplorerExtension.
Add these references to the project:
Note: These references may be in different places in each computer.
this is what my references section in csproj contains:
<Reference Include="Interop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=90ba9c70f846762e, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<EmbedInteropTypes>True</EmbedInteropTypes>
<HintPath>C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies\Interop.SHDocVw.dll</HintPath>
</Reference>
<Reference Include="Microsoft.CSharp" />
<Reference Include="Microsoft.mshtml, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<EmbedInteropTypes>True</EmbedInteropTypes>
</Reference>
<Reference Include="System" />
<Reference Include="System.Data" />
<Reference Include="System.Drawing" />
<Reference Include="System.Windows.Forms" />
<Reference Include="System.Xml" />
Create the files the same way as the updated IE11 files.
IEAddon.cs
You can uncomment the following lines from IE11 version:
...
// @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;
...
Interop.cs
Same as IE11 version.
and finally a form, that we will use to configure the options. In this form place a http://msdn.microsoft.com/en-us/library/ms976373.aspx#bho_getintouch and an Ok gacutil.exe. Set the DialogResult of the button to Ok. The code is the same for IE11 addon.
In the project properties, do the following:
TextBoxButtonIn the Build Events tab, set Post-build events command line to:
"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\x64\gacutil.exe" /f /i "$(TargetDir)$(TargetFileName)" "C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" /unregister "$(TargetDir)$(TargetFileName)" "C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" "$(TargetDir)$(TargetFileName)"
Attention: as my computer is x64, there is a specific x64 inside the path of gacutil executable on my machine that may be different on yours.
64bit IE Needs 64bit-compiled and 64bit-registered BHO. Use 64bit RegAsm.exe (usually lives in C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe)
How this add-on works
It traverses all DOM tree, replacing the text, configured using the button, by itself with a yellow background. If you click on the yellowed texts, it calls a javascript function that was inserted on the page dynamically. The default word is 'browser', so that it matches a lot of them! EDIT: after changing the string to be highlighted, you must click the URL box and press Enter... F5 will not work, I think that it is because F5 is considered as 'navigation', and it would require to listen to navigate event (maybe). I'll try to fix that later.
Now, it is time to go. I am very tired. Feel free to ask questions... may be I will not be able to answer since I am going on a trip... in 3 days I'm back, but I'll try to come here in the meantime.

另一个很酷的方法是检查:
它是一个基于JS和jquery的框架,它允许您使用一个通用的JS代码为IE,FF和Chrome开发浏览器扩展.基本上,框架可以完成所有令人讨厌的工作,而您只需要编写应用程序代码.
clo*_*ven 11
IE扩展的状态实际上非常悲伤.你有IE5浏览器助手对象的旧模型(是的,那些臭名昭着的BHO,每个人都喜欢在当天阻止),工具栏和IE的新加速器.即便如此,兼容性有时会破裂.我过去常常维护IE6的扩展,但是有些东西已经改变了.在大多数情况下,据我所知(我多年没有接触过BHO)你仍然需要使用活动模板库(类似于微软COM的STL)对它们进行编码,这样只适用于C++.您可以使用C#进行COM Interop,并在C#中完成它,但它可能对于它的价值来说太难了.无论如何,如果你有兴趣编写你自己的IE扩展(如果你想在所有主流浏览器中使用你的扩展,这是合理的)这里是官方微软资源.
http://msdn.microsoft.com/en-us/library/aa753587(v=vs.85).aspx
对于IE8中新增的加速器,您可以查看这个.
http://msdn.microsoft.com/en-us/library/cc289775(v=vs.85).aspx
我同意文档很糟糕,API已经过时了.我仍然希望这会有所帮助.
编辑:我想我可以在这里抛出最后一个信息来源.当我在BHO工作时,我正在查看我的笔记.这篇文章让我开始了.它有点旧,但对使用IE BHO(例如IObjectWithSite)时将使用的ATL接口有一个很好的解释.我认为它很好地解释了,并帮助了我很多. http://msdn.microsoft.com/en-us/library/bb250436.aspx 我还检查了GregC发布的示例.它至少适用于IE8,它与VS 2010兼容,所以如果你想做C#,你可以在那里开始看看Jon Skeet的书.(深度第2版中的C#)第13章提供了大量有关C#4中新功能的信息,您可以使用它们来更好地与COM进行交互.(我仍然建议你在C++中使用你的插件)
开发C#BHOs是一种痛苦的蠢事.它涉及许多icky COM代码和p/invoke调用.
我有一个基本完成C#BHO 在这里,您可以自由使用来源为任何你想要的.我说"大多数",因为我从未弄清楚如何在IE保护模式下保存appdata.
