Hi

I need to use a numbering system in my VB.net app that increments by one every time
I perform an action. I want it to start at 1 then move to 2, then 3 and so on.
What VB.net code would I use to write a text file that handles this?

Thanks

Create a counter variable and add 1 every time that action is preformed.

Dim iCounter As Integer = 0
Dim FILE_NAME As String = "C:\Users\Owner\Documents\test.txt"

If System.IO.File.Exists(FILE_NAME) = True Then
    Dim oWriter As New System.IO.StreamWriter( FILE_NAME )
    oWriter.Write(TextBox1.Text)
    oWriter.Close()
    iCounter = iCounter + 1
    MsgBox("Text written to file")
Else
    MsgBox("File Does Not Exist")
End If
