利用宏从Word、Excel中提取Flash

今天网上弄到个flash游戏，感觉挺不错的，但是flash被嵌在了excel中，想单独保存出来。百度了一下找到如下宏代码可以实现。
Sub CollectFlashFromExcel()
'

'

'
Dim tmpFileName As String, FileNumber As Integer
Dim myFileId As Long
Dim myArr() As Byte
Dim i As Long
Dim MyFileLen As Long, myIndex As Long
Dim swfFileLen As Long
Dim swfArr() As Byte
 

tmpFileName = Application.GetOpenFilename("office File(*.doc;*.xls),*.doc;*.xls", , "请选择一个包含Flash的Office文档")

 
If tmpFileName = "False" Then Exit Sub

myFileId = FreeFile

Open tmpFileName For Binary As #myFileId

MyFileLen = LOF(myFileId)

ReDim myArr(MyFileLen - 1)
Get myFileId, , myArr()
Close myFileId

Application.ScreenUpdating = False

i = 0

Do While i < MyFileLen

    If myArr(i) = &H46 Then

        If myArr(i + 1) = &H57 And myArr(i + 2) = &H53 Then

            swfFileLen = CLng(&H1000000) * myArr(i + 7) + CLng(&H10000) * myArr(i + 6) + CLng(&H100) * myArr(i + 5) + myArr(i + 4)

            ReDim swfArr(swfFileLen - 1)

            For myIndex = 0 To swfFileLen - 1

                swfArr(myIndex) = myArr(i + myIndex)

            Next myIndex
           Exit Do
        Else
           i = i + 3
        End If
    Else
       i = i + 1
    End If
Loop

 

myFileId = FreeFile

tmpFileName = Left(tmpFileName, Len(tmpFileName) - 4) & ".swf"

Open tmpFileName For Binary As #myFileId

Put #myFileId, , swfArr

Close myFileId


MsgBox "以" & tmpFileName & "名字保存"

End Sub

 

 打开（或新建）一个excel文档，将上述代码输入宏试图中，然后运行，再代开含有flash的excel或word文档就能将flash文档的从word、Excel中提取出来了。
