File Permissions

lilgirllilgirl Posts: 14Member
Hi,

I am trying to make a file read only in VB.

My code is as follows:

[code]
Dim f2 As New System.Security.Permissions.FileIOPermission(System.Security.Permissions.FileIOPermissionAccess.NoAccess, filen)
MsgBox("locked")
[/code]

Once the message box appears and I open the file, it allows me to write to it. What am I missing? Any thoughts are appreciated.

Thanks.

    As it's several days since you posted your question, you've probably already found a fix. However, in case not, here's a different approach which will make a file readonly:
    [code]
    Dim myfile As File
    myfile.SetAttributes("c:demo1.txt", FileAttributes.ReadOnly)
    [/code]
    You can set any of the usual attributes of a file using code similar to the above. And of course you can check it's state by using the GetAttributes method.
