C#在IE右键菜单中添加自定义项的实现代码
首先，增加注册表项 HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\MyApp
MyApp为要显示在右键菜单中的名称
VBScript处理脚本，新增的注册表项的默认值是包含这个VBScript脚本的Html页面地址。
1、添加注册表项：
/// <summary>
/// 在IE中增加右键菜单
/// </summary>
static void RegistryIeContextMenu() {
try {
string regkey = @"Software\Microsoft\Internet Explorer\MenuExt\MyApp";
string scriptPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "geturl.htm");
RegistryKey root = Registry.CurrentUser.OpenSubKey(regkey);
if (null == root) {
root = Registry.CurrentUser.CreateSubKey(regkey);
root.SetValue("", scriptPath, RegistryValueKind.String);
root.SetValue("Contexts", 0x00000022, RegistryValueKind.DWord);
}
} catch (Exception ex) {
DFApp.LogDebug(ex.ToString());
}
}
2、脚本geturl.htm
<script language="VBScript">
Sub AddLink(Url,Info,Location)
On Error Resume Next
if Url <> "" then
if Info = "" then
Info = "unknown"
end if
if Len(Info) > 1000 then
Info = Left(Info, 1000)
end if
DownloadInfo = Url "^" Info
set shell = CreateObject("Wscript.Shell")
shell.Run "C:\MyApp.EXE " DownloadInfo
end if
end sub
Sub OnContextMenu()
set srcEvent = external.menuArguments.event
set srcLocation = external.menuArguments.location
set EventElement = external.menuArguments.document.elementFromPoint ( srcEvent.clientX, srcEvent.clientY )
if srcEvent.type = "MenuExtAnchor" then
set srcAnchor = EventElement
do until TypeName(srcAnchor)="HTMLAnchorElement"
set srcAnchor=srcAnchor.parentElement
Loop
Call AddLink(srcAnchor.href,srcAnchor.innerText,srcLocation)
elseif srcEvent.type="MenuExtImage" then
if TypeName(EventElement)="HTMLAreaElement" then
Call AddLink(EventElement.href,EventElement.Alt,srcLocation)
else
set srcImage = EventElement
set srcAnchor = srcImage.parentElement
do until TypeName(srcAnchor)="HTMLAnchorElement"
set srcAnchor=srcAnchor.parentElement
if TypeName(srcAnchor)="Nothing" then
call AddLink(srcImage.href,srcImage.Alt,srcLocation)
exit sub
end if
Loop
Call AddLink(srcAnchor.href,srcImage.Alt,srcLocation)
end if
elseif srcEvent.type="MenuExtUnknown" then
set srcAnchor = EventElement
do until TypeName(srcAnchor)="HTMLAnchorElement"
set srcAnchor=srcAnchor.parentElement
if TypeName(srcAnchor)="Nothing" then
Call AddLink(EventElement.href,EventElement.innerText,srcLocation)
exit sub
end if
Loop
Call AddLink(srcAnchor.href,srcAnchor.innerText,srcLocation)
elseif 1=1 then
MsgBox("Unknown Event Source """ srcEvent.type """" vbCrLf "Please send description of error to test@jbxue.com")
end if
end sub
call OnContextMenu()
</script>
