由于以前写过个播放器,硬盘里也放着不少Flash文件,不少是EXE格式的.
也下载过一些小程序转换,现在闲着没事,自己也写了一个小程序...但
'''''函数功能:输入SWF或EXE格式的Flash文件
Private Sub OutputFlash(InputFile As String, Outputfile As String)
Dim bittmp() As Byte
Dim FileLenth&, I&, J&
Dim FileNum1 As Integer
Dim FileNum2 As Integer
Dim strFwsFlag As String
Dim strHexFlag As String
Dim strVAR As String
Dim bitVAR As Byte
Dim swfSize As Long
Dim swfStartPostion As Long
FileLenth = FileLen(InputFile)
S = "&H"
FileNum1 = FreeFile: Open InputFile For Binary As #FileNum1
FileNum2 = FreeFile: Open Outputfile For Binary As #FileNum2
Dim sss$: sss = Time
For I = FileLenth To FileLenth - 3 Step -1
Seek #FileNum1, I '''文件指针位置
t = AscB(StrConv((Input(1, #FileNum1)), 128)) '''字符串ASCII码
s = s & Hex(Int(t / 16)) & Hex(Int(t Mod 16)) '''双字16进制
Next
sss = sss & ">" & Time '''Record TIME
swfSize = Val(s) '''SWF文件大小
swfStartPostion = FileLenth - swfSize - 7 ''SWF文件开始地址
Seek #FileNum1, swfStartPostion
strVAR = Asc(Input(3, #FileNum1))
If strVAR = 70 Or strVAR = 67 Then '''正确查找到FWS标记
Dim startByte&: startByte = swfStartPostion
sss = sss & ">" & Time
ReDim bittmp(swfSize) As Byte
For I = 1 To swfSize
Get #FileNum1, swfStartPostion + I - 1, bittmp(I)
Next
For I = 1 To swfSize '''输出SWF格式的文件
Put #FileNum2, I, bittmp(I)
Next
sss = sss & ">" & Time ''Record TIME
Close #FileNum2
Skf.Movie = Outputfile
Else
MnuShowText.Caption = "Sorry! Can't Output SWF-Flash File"
tmr = True
End If
Close #FileNum1
sss = sss & ">" & Time ''Show Time
Me.Caption = sss
End Sub
每次写文件,读文件都是一个一个字节读写.所以速度很慢!
