سلام

انا جرب هذا الكود وحفظ وعرض بنفس التنسيق بدون مشكله

كود :

Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
    My.Settings.serial = TextBox1.Text
End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    TextBox1.Text = My.Settings.serial
End Sub

موفقين
