如何取出ppt中的flash

新建一个excel文档,在“开发工具”选项卡下面单击“vb”按钮,进入编程状态,单击“插入”菜单下的“模块”命令,在弹出的窗口中粘贴下面代码:

Sub ExtractFlash()

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", , "

确定要分析的 Office 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

粘贴好了以后返回到excel主界面,把该excel文档起一个你容易辨识的名字,保存为“启用宏的工作簿”,留着用来提取

swf文件。

打开嵌入了swf文件的ppt,在swf文件上右键单击,选择复制,新建一个excel文件,在新建的excel文件里右键“粘贴”,把

ppt里的swf文件复制过来,起个名字,保存为excel 97—2003工作薄(这里面的版本选择很重要,不要选错),保存好了关闭该excel。

打开我们第一个粘贴有代码的excel文档,在“开发工具”下,单击“宏”,弹出宏对话框,单击“执行”,在打开的窗口中选择粘贴有swf文件的excel文件,大功告成,里面的swf马上就会被提取出来。
