Dir function doesn't work properly

[Theo]

Hi all,

Im trying to use the Dir function to determine wether a certain image excists or not. But the variable strDir is always empty, even when an image does excist. (see code below).

    Public Function getIMG(ByVal pItem As String) As String
        Dim strDir As String

        strDir = Dir("Z:\images\" & pItem & ".jpg")

        Return strDir
    End Function

- The parameter pItem is the name of the image without the extension.
- All the images have NO attributes

The Dir function is really a legacy VB function (and it wasnt that good then) - Try using the classes under System.IO.

e.g.

If System.IO.File.Exists("z:\images\" & pItem & ".jpg")

Ive adapted my function like you can see below, but without any result. It seems like ASP.NET isnt able to see the existing images.

    Public Function getIMG(ByVal pItem As String) As String
        Dim strDir As String

        If System.IO.File.Exists("Z:\afbeeldingen\" & pItem & ".jpg") = True Then
            strDir = "Z:\afbeeldingen\" & pItem & ".jpg"
        Else
            strDir = "blank"
        End If

        Return strDir
    End Function

Does the ASPNET account have permissions to the Z:\afbeeldingen folder?

Does the ASPNET account have permissions to the Z:\afbeeldingen folder?

That seemed to be the problem. I copied the images to the local drive and now it works fine. So it must be the permissions indeed.

Thanks!
