Public Class ApplicantsInfo3
    Dim data As DatabaseClass = New DatabaseClass()

    Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ApplicantsInfo2.Show()
        Me.Hide()
    End Sub

    Private Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
        CloseApplicantsInfo()
       
    End Sub

    Public Sub CloseApplicantsInfo()
        ApplicantsInfo1.Close()
        ApplicantsInfo2.Close()
        Me.Close()
        ApplicantsView.Show()
        ApplicantsView.pageInit()
    End Sub

    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Dim validate = New Validators()


        If validate.validateUserInfo() = True Then
            If ApplicantsInfo1.txtApplicantID.Text = "" Then
                data.AddApplicant()
            Else
                data.AddAnAdministrator()
            End If
        Else
            MsgBox("failed")
        End If
        'Me.Close()
        'ApplicantsInfo1.Close()

        'ApplicantsView.Show()
        CloseApplicantsInfo()
    End Sub


    Private Sub txtDataIssued_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub

    Private Sub ApplicantsInfo3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I hope that this time. someone can help me. I keep on posting and posting threads but it seems no one is helping. and I'm so sick and tired since I registered here just to shout for help about programming. this is the only key for me to graduate this year. nothing is helping me, my threads are always empty. I feel like I'm stupid that keeps on coming back but no one, please... even the mods. help me with my system codes. god bless
