打开一个Excel,在视图页面创建一个宏如下
Sub aa()
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

F5运行宏,选择文件,即可在文件当前目录保存swf文件
