I have a combobox that i want to save to a textfile when clicking a button, it should append all entries to a new line UNLESS it already exists. I have the below code, but it doesnt save, it doesnt do anything, but no errors.

   Dim content(TextBox1.Items.Count - 1) As String
        TextBox1.Items.CopyTo(content, 0)
        IO.File.WriteAllLines("C:\SWDEPOT\test.txt", content)

Open in new window


If a prepopulate the textfile with entries i am able to load it completely fine with the below code:

Dim load() As String = IO.File.ReadAllLines("C:\SWDEPOT\test.txt")
        Array.Reverse(load)
        TextBox1.Items.AddRange(load)

Something like this should work:

    Const filePath As String = "C:\SWDEPOT\test.txt"

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        ' Adds new text
        If TextBox1.SelectedIndex = -1 AndAlso TextBox1.Text <> "" Then
            IO.File.AppendAllText(filePath, TextBox1.Text & vbNewLine)
        End If

        ' Clear previous information
        TextBox1.Items.Clear()

        ' Load the information from the text file
        Dim load() As String = IO.File.ReadAllLines(filePath)
        Array.Reverse(load)
        TextBox1.Items.AddRange(load)

    End Sub
