    VB获取和更改文件属性

    摘自网络供自己备查!

    Private Declare Function SetFileAttributes Lib "kernel32" Alias "SetFileAttributesA" (ByVal lpFileName As String, ByVal dwFileAttributes As Long) As Long
    Private Declare Function GetFileAttributes Lib "kernel32" Alias "GetFileAttributesA" (ByVal lpFileName As String) As Long
    Private Const FILE_ATTRIBUTE_ARCHIVE = &H20
    Private Const FILE_ATTRIBUTE_COMPRESSED = &H800
    Private Const FILE_ATTRIBUTE_DIRECTORY = &H10
    Private Const FILE_ATTRIBUTE_HIDDEN = &H2
    Private Const FILE_ATTRIBUTE_NORMAL = &H80
    Private Const FILE_ATTRIBUTE_READONLY = &H1
    Private Const FILE_ATTRIBUTE_SYSTEM = &H4
    Private Const FILE_ATTRIBUTE_TEMPORARY = &H100

    修改:
    Private Sub Command1_Click()
    SetFileAttributes "C:\1.txt", 1
    End Sub

    Private Sub Command2_Click()
    SetFileAttributes "C:\1.txt", 2
    End Sub

    判断:

    Private Sub Command1_Click()
    Print GetAttr("C:\Autoexec.Bat")
    If GetFileAttributes("C:\1.Bat") And 1 Then Print "此文件只读"
    If GetFileAttributes("C:\1.Bat") And 2 Then Print "此文件隐藏"
    If GetFileAttributes("C:\1.Bat") And 4 Then Print "此文件为系统文件"
    If GetFileAttributes("C:\1.Bat") And 16 Then Print "此文件为文件夹"
    If GetFileAttributes("C:\1.Bat") And 32 Then Print "此文件为保存属性"
    End Sub

    其中属性值:
    0 一般
    1 只读
    2 隐藏
    4 系统
    16 文件夹
    32 保存属性

    要加多个属性的话可以写成: SetFileAttributes "C:\1.txt", 1 + 2 + 32

    Cacls.exe 命令行下修改文件访问控制权限

    不多写了自己慢慢去研究吧!!
