Saving and loading a listbox from .txt

I cant seem to fing the this answer in .net so...I need to save listbox1 to a .txt in my documeants and then be able to load it. How whould i do this? Thanks

You need to use the System.IO.FileStream, System.IO.StreamWriter, and System.IO.StreamReader classes..

Ex:

VB Code:

Private Sub readComboItems(.......
     Dim fs as System.IO.FileStream
     Dim sw as System.IO.StreamWriter
     Dim its as String
           fs = New System.IO.FileStream("your file path\filename.txt", IO.FileMode.OpenOrCreate)
           sw = System.IO.StreamWriter(fs)
 
           For each its in Me.Combo1.Items
              sw.WriteLine
              sw.Flush
           Next
 
End Sub

To read them back into a combo box:

VB Code:

Private Sub writeComboItems(.......
     Dim fs as System.IO.FileStream
     Dim sr as System.IO.StreamReader
     Dim lineVal as String
           fs = New System.IO.FileStream("your file path\filename.txt", IO.FileMode.Open)
           sr = System.IO.StreamReader(fs)
 
           Do
               lineVal = sr.ReadLine
               If lineVal is nothing then exit do
               me.ComboBox1.Items.Add(lineVal)
          Loop
End Sub

Hope this helps

Sorry. Just noticed you said listbox not combo box...too much NyQuil... Should work the same regardless.

thanks for the response. It says sw = System.IO.StreamWriter(fs) is an IO and can not be used as an expression

Send me what you have written. Take out any proprietary info first.

hers what i got

VB Code:

Dim fs As System.IO.FileStream
        Dim sw As System.IO.StreamWriter
        Dim its As String
        fs = New System.IO.FileStream("C:\My documents\attacklist.txt", IO.FileMode.OpenOrCreate)
        sw = System.IO.StreamWriter(fs)
 
        For Each its In Me.ListBox1.Items
            sw.WriteLine()
            sw.Flush()
        Next

nvm i got it to work, i changed it around a little:

VB Code:

Dim SW As StreamWriter
            Dim Fs As FileStream
        Fs = New FileStream("C:\my documents\attacklist.txt", FileMode.Create)
            SW = New StreamWriter(Fs)
            Dim itm As Object
            For Each itm In ListBox1.Items
                SW.WriteLine(itm.ToString)
            Next 
            SW.Close()
            Fs.Close()

now useing that code how whould i use the save dialog function?

try this now :

VB Code:

Dim SW As StreamWriter
        Dim Fs As FileStream
 
        Dim fd As New SaveFileDialog
        If fd.ShowDialog = DialogResult.OK Then
            Fs = New FileStream(fd.FileName, FileMode.Create)
            SW = New StreamWriter(Fs)
            Dim itm As Object
            For Each itm In ListBox1.Items
                SW.WriteLine(itm.ToString)
            Next
            SW.Close()
            Fs.Close()
        End If
