实现方法

要添加这种自定义按钮，需要在Windows注册表的HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Extensions子键下建立一个GUID项，然后在注册表的右栏建立相应的参数并赋值。这些参数及其含义如下：
●ButtonText：自定义按钮上显示的文本字符串；
●Clsid：IE工具条的类标识码，为“{1FBA04EE－3024－11D2－8F1F0000F87ABD16}”；
●Default Visible：自定义按钮是否可见，一般为 “Yes"；
●Exec：自定义按钮执行的目标，为可执行文件或超文本链接等；
●HotIcon：鼠标移上按钮时显示的图标，一般取自EXE文件或DLL文件；
●Icon：按钮正常显示的图标，一般取自EXE文件或DLL文件；
●MenuText：在IE的“工具”菜单中显示的菜单项；
●MenuStatusBar：IE的“工具”菜单项的注释，在状态条上显示。

制作过程

在VB 5.0或6.0下建立新的“ActiveX 控件”工程。
首先，给控件AddButton的Picture属性添加一个微型Icon图片。这样，当使用该控件时，会在控件工具箱上显示这个小图标。然后，再在设计窗口上放置一个image控件，给它也设置一个小图片，使用该控件时，会在其Form上显示该控件的外观。最后，调出代码编辑窗口，在该窗口中键入以下代码，其中API函数调用的代码可以直接从“API文本浏览器”中获得。
