如何用VB对WIN2000共享的文件设置权限为只读

2000系统下API实现目录共享/删除

ACCESS_READ

共享类型
Private Const STYPE_ALL As Long = -1
Private Const STYPE_DISKTREE As Long = 0
Private Const STYPE_PRINTQ As Long = 1
Private Const STYPE_DEVICE As Long = 2
Private Const STYPE_IPC As Long = 3
Private Const STYPE_SPECIAL As Long = &H80000000

'共享权限
Private Const ACCESS_READ As Long = &H1
Private Const ACCESS_WRITE As Long = &H2
Private Const ACCESS_CREATE As Long = &H4
Private Const ACCESS_EXEC As Long = &H8
Private Const ACCESS_DELETE As Long = &H10
Private Const ACCESS_ATRIB As Long = &H20
Private Const ACCESS_PERM As Long = &H40
Private Const ACCESS_ALL As Long = ACCESS_READ Or _
ACCESS_WRITE Or _
ACCESS_CREATE Or _
ACCESS_EXEC Or _
ACCESS_DELETE Or _
ACCESS_ATRIB Or _
ACCESS_PERM

'共享信息
Private Type SHARE_INFO_2
shi2_netname As Long '共享名
shi2_type As Long '类型
shi2_remark As Long '备注
shi2_permissions As Long '权限
shi2_max_uses As Long '最大用户
shi2_current_uses As Long '
shi2_path As Long '路径

'设置共享

'删除共享

'设置共享

End Sub

'设置共享(返回0 为成功)

您好，单击文件，右键单击，选择属性，将文件设置为只读就行了。

就把文件属性设为只读,就行了
