First, I made two subs, the LoadFromFile and SavetoFile customized to fit the needs of the app:
After you have added these subs to your code, then all you have to do is load the file when the app starts, and save to it when the app ends:Code:Public Sub SaveToFile(ByVal file As String)
Dim text As String = "" 'this string represents what will be written to the file
For Each item As String In ListBox1.Items
text = text + item + "|" 'iterate through all items in the listbox and write them in text("|" will be used as delimeter when loading)
Next
text = text.Remove(text.Length - 1) 'last "|" is removed
text = text + ";"
For Each item As String In password
text = text + item + "|" 'iterate through all items in the password list and write them in text("|" will be used as delimeter when loading)
Next
text = text.Remove(text.Length - 1) 'last "|" is removed
System.IO.File.WriteAllText(file, text) 'write to file specified
End Sub
Public Sub LoadFromFile(ByVal file As String)
If System.IO.File.Exists(file) Then 'tests if file specified exists
Dim text As String = System.IO.File.ReadAllText(file) 'reads from file specified
Dim lists() As String = text.Split(";") 'lists() will now contain 2 items: the 1st is listbox items, the 2nd password items
Dim ListItems() As String = lists(0).Split("|") 'ListItems now contains listbox items
Dim PasswordItems() As String = lists(1).Split("|") 'PasswordItems now contains password items
'clear the listbox and password in case they have something
ListBox1.Items.Clear()
password.Clear()
For Each item As String In ListItems
ListBox1.Items.Add(item) 'iterate through all items in listitems and add them to the listbox
Next
For Each item As String In PasswordItems
password.Add(item) 'iterate through all items in passworditems and add them to the password list
Next
End If
End Sub
Code:Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
SaveToFile("example.txt")
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadFromFile("example.txt")
End Sub
I hope this code helps and is easy to understand. I have added as many comments as I could.
Thanks.
