利用宏功能导出excel中的flash文件

1.     点击工具——>宏——>宏

2.     弹出一个宏创建窗体,在窗口中输入宏名（例如：宏名：ExtractFlash）点击创建按钮。

3.     弹出一个编程界面，在界面的中间有一个小窗口，在窗口中输入下面的程序段。

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", , "確定要分析的 Office 檔")



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

4.     按F5运行宏。

5.     弹出一个选择文件的窗口，选择你想要提取flash的excel文件，点击打开按钮。

6.     这时会弹出一个提示窗口“以......名字保存”，点击确定。

7.     在excel所在的位置会产生一个同名的flash文件。到此flash文件已经导出了。
