小弟最近參考一個更改file property的程式
http://stackoverflow.com/questions/750679/how-do-you-make-a-file-writeable-in-
vb
Dim fso As New FileSystemObject
Dim fil As File
Set fil = fso.GetFile("C:\foo.txt")
If (fil.attributes And vbReadOnly) Then
fil.attributes = fil.attributes -vbReadOnly
End If

32 and 1 =0 ?
請問在這裡and的作用

這是 bitwise and
