I was wondering if i would be able have the saved items as a way to "login" to my program. in the first form (form1) i have a masked textbox and a button. you type your "pin" into the masked textbox and click the button to enter. i would like to check the masked textbox against listbox for a correct "pin". my code for that is:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If Form4.ListBox1.Items.Contains(MaskedTextBox1.Text) Then Button3.Visible = True Button3.Enabled = True Else MsgBox("Your Pin was incorrect. Please try again.") Button3.Visible = False Button3.Enabled = False MaskedTextBox1.Text = "" End If End Sub
I cant check the masked textbox against the other form (form4) to have the "pins" in the listbox to work when saved with this cods:
Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Dim filePath As String = "C:\Myfile.txt" 'use your path! If Not File.Exists(filePath) Then Dim fs As FileStream = File.Create(filePath) fs.Close() End If Using fs As New FileStream(filePath, FileMode.CreateNew, FileAccess.Write) Using sw As New StreamWriter(fs) For Each item As String In listBox1.Items sw.WriteLine(item) Next End Using End Using End Sub
any ideas on how to fix this?
