提取Excel、Word、PPT文件中的Flash文件的两种方法

方法一：VBA代码法

新建一个文件，然后拷贝以下代码到VBA模块中，运行代码，选择含有Flash的Excel文件确定，即可获取swf文件。

Sub ExtractFlash()

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

tmpFileName = Application.GetOpenFilename("MS Office File (*.doc;*.xls), *.doc;*.xls", , "Open MS Office file")

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 "Save the extracted SWF Flash as [ " & tmpFileName & " ]"

End Sub

方法二：UE修改法

1、打开这个含有Flash的Excel文件，进入设计模式，选中这个Flash后拷贝到桌面，获取一个片段文件
2、用ULraEdit32(UE)打开这个片段文件，查找“465753”字段
3、把“465753”字段之前的文字全部剪切，然后把文件另存为”X.swf”
4、OK
