提取Win9x拷贝的动画

Win9x的文件拷贝既有动画，又有复制进度条显示，Vb中如何实现？此动画能
在Windows中提取出来吗？
A:
拷贝文件用SHFileOperation函数，例如：
Option Explicit
Private Type SHFILEOPSTRUCT
hwnd As Long
wFunc As Long
pFrom As String
pTo As String
fFlags As Integer
fAnyOperationsAborted As Boolean
hNameMappings As Long
lpszProgressTitle As String
End Type
Private Declare Function SHFileOperation Lib "shell32.dll" Alias
"SHFileOperationA" _
(lpFileOp As SHFILEOPSTRUCT) As Long
Private Const FO_COPY = &H2
Private Sub Form_Load()
Dim lResult As Long, SHF As SHFILEOPSTRUCT
SHF.hwnd = hwnd
SHF.wFunc = FO_COPY
SHF.pFrom = "E:\Linux\linux-2.2.2.tar.gz"
SHF.pTo = "C:\"
lResult = SHFileOperation(SHF)
End Sub
