Go to the project Properties, then click on "Settings" down the left side. Add as many string variables as you have text boxes to save. For example, if you add the string setting, MyText1 you can load the textbox on form load as
TextBox1.Text = My.Settings.MyText1
and save the value on form close for the next run as
My.Settings.MyText1 = TextBox1.Text
I have 24 textboxes textbox1 textbox2 textbox3 etc, and 11 maskedtextboxes maskedtextbox1 maskedtextbox2 maskedtextbox3 etc
could someone post a code snippet of what this would look like? (maybe one or two of each not all 35 textboxes...) and settings or anything i need to change? thanks much :)
See if this helps.

Public Class Form1
Private myCoolFile As String = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) & "\test.txt" '// your file.
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
File.WriteAllText(myCoolFile, saveCoolControls("TextBox", 3) & vbNewLine & saveCoolControls("MaskedTextBox", 3)) '// overwrite/create file.
End Sub
Private Function saveCoolControls(ByVal selCoolControlType As String, ByVal numberOfCoolControls As Integer) As String
Dim sTemp As String = ""
For i As Integer = 1 To numberOfCoolControls '// loop thru controls on Form.
With CType(Me.Controls(selCoolControlType & i), Control) '// locate specified control.
If Not sTemp = "" Then sTemp &= vbNewLine '// saves lines and adds line.breaks.
sTemp &= .Name & ":" & .Text '// add .Name and .Text to save and load from, separated by ":".
End With
Next
Return sTemp '// return the data for saving.
End Function
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If IO.File.Exists(myCoolFile) Then '// check if file exists.
For Each itm As String In File.ReadAllLines(myCoolFile) '// load file content in Array.
If Not itm = "" Then '// verify that line has content.
With itm '// locate ctl by name and add value to it.
CType(Me.Controls(.Substring(0, .IndexOf(":"))), Control).Text = .Substring(.IndexOf(":") + 1)
End With
