Get file size

How do I get the size of a file?

VB Code:

Imports System
Imports System.IO
Public Module modmain
   Sub Main()
      'KPD-Team 2001
      'URL: [url]http://www.allapi.net/dotnet/[/url]
      'E-Mail: [email][email protected][/email]
      Dim MyFile as new FileInfo ("c:\autoexec.bat")
      Console.WriteLine("The length of autoexec.bat is " _
         + MyFile.Length.ToString + " bytes.")
   End Sub
End Module

Hey thanks for the quick reply. If you could answer a few more noob questions, you will help me on my way.

I tried to use the same technique to get a dirs parent dir....but no luck

VB Code:

Private Sub SearchDir(ByVal TargetDir As String)
        Dim Files() As String
        Dim File As String
        Dim Dirs() As String
        Dim Dir As String
        Dim FileInfo As IO.FileInfo
        Dim DirInfo As IO.DirectoryInfo
 
 
        Dirs = IO.Directory.GetDirectories(TargetDir)
        lstDirs.Items.Clear()
        lstDirs.Items.Add("UP")
        For Each Dir In Dirs
            lstDirs.Items.Add(Dir)
        Next
 
        Files = IO.Directory.GetFiles(TargetDir, "*.*")
        lsvFiles.Items.Clear()
        For Each File In Files
            'add item to list view box
            lsvFiles.Items.Add(File)
            FileInfo = New IO.FileInfo(File)
            lsvFiles.Items(lsvFiles.Items.Count - 1).SubItems.Add(FileInfo.Length)
        Next
 
        'store parent directory
        DirInfo = New IO.DirectoryInfo(TargetDir)
        UpDir = DirInfo.Parent.ToString     'causes error
    End Sub

Also, how do you change the mouse cursor? In VB6...twas

VB Code:

me.mousepointer = vbhourglass
me.mousepointer = vbDefault

??????
?????
????

umm for the cursor:
Me.Cursor = Cursors.WaitCursor

to get a direcotory's parent DIR, I tried this, dunno if it's what you're looking for:

System.IO.Directory.GetParent("C:\windows\system").FullName()



btw I tried your code like this:
Dim dirInfo As New IO.DirectoryInfo("c:\windows\system")
MsgBox(dirInfo.Parent.ToString)

it works, maybe you are passing something weirdo to the function, I didnt really read you code:D
umm and what's the error anyways? :rolleyes:


HTH:)

Thanks Mr.Polite. You have been a great help.

The cursor code worked great. Here is what I ended up using for the DirInfo

VB Code:

dim DirInfo as IO.DirectoryInfo
 
'later in sub (in a loop)
DirInfo = New IO.DirectoryInfo(TargetDir)
UpDir = DirInfo.Parent.FullName

The problem was that I was passing the root of the drive as the TargetDir and that was causing an error. I just needed some error handling.
