VB里面怎么删除IE的Cookie？

注意，用kill我试过了，不行！！

Option Explicit
Private Const NO_ERROR = 0
Private Const INTERNET_OPTION_END_BROWSER_SESSION = 42
Private Const CSIDL_COOKIES = &H21&
Private Type SHITEMID
cb As Long
abID As Byte
End Type
Private Type ITEMIDLIST
mkid As SHITEMID
End Type
Private Declare Function ShellAbout Lib "shell32.dll" Alias "ShellAboutA" (ByVal hWnd As Long, ByVal szApp As String, ByVal szOtherStuff As String, ByVal hIcon As Long) As Long
Private Declare Function SHGetSpecialFolderLocation Lib "shell32.dll" (ByVal hwndOwner As Long, ByVal nFolder As Long, pidl As ITEMIDLIST) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32.dll" Alias "SHGetPathFromIDListA" (ByVal pidl As Long, ByVal pszPath As String) As Long
Private Declare Function InternetSetOption Lib "wininet.dll" Alias "InternetSetOptionA" (ByVal hInternet As Long, ByVal dwOption As Long, ByRef lpBuffer As Any, ByVal dwBufferLength As Long) As Long

Private Function GetSpecialfolder(CSIDL As Long) As String
Dim r As Long
Dim IDL As ITEMIDLIST
'Get the special folder
Dim path As String
r = SHGetSpecialFolderLocation(100, CSIDL, IDL)
If r = NO_ERROR Then
'Create a buffer
path = Space$(512)
'Get the path from the IDList
r = SHGetPathFromIDList(ByVal IDL.mkid.cb, ByVal path$)
'Remove the unnecessary chr$(0)'s
GetSpecialfolder = Left$(path, InStr(path, Chr$(0)) - 1)
Exit Function
End If
GetSpecialfolder = ""
End Function

Private Sub Command1_Click()
Dim CookiesPath As String
CookiesPath = GetSpecialfolder(CSIDL_COOKIES) '获取COOKIES文件夹路径
'为了防止在ie打开时，内存中还有部分COOKIES存在，加了下面这句
Call InternetSetOption(0, INTERNET_OPTION_END_BROWSER_SESSION, ByVal 0&, 0)
Kill CookiesPath + "\*.txt" '全部删除，如果需要删除某一个COOKIES的话，需要用dir或fso枚举出所有文件，然后用kill语句删除
End Sub

有一个方法，可以删除C:\documents & settings\用户名\local settings\Temporary Internet Files下面的所有目录中的文件，就可以清除缓存和Cookie了
