Imports System.Text.RegularExpressions

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        If txtFULLNAME.Text = "" Then
            Form6.Show()
            Form6.Label1.Text = "You must enter your Full Name"
        ElseIf txtEMAIL.Text = "" Then
            Form6.Show()
            Form6.Label1.Text = "You must enter your Email Address"
        Else
            Form5.Show()
            Form2.txtFULLNAME.Text = txtFULLNAME.Text
            Form3.txtFULLNAME.Text = txtFULLNAME.Text
            Form4.txtFULLNAME.Text = txtFULLNAME.Text
            Form5.txtFULLNAME.Text = txtFULLNAME.Text
            Form2.txtEMAIL.Text = txtEMAIL.Text

Trying to figure out how to insert the Regex in to what is above to have it work properly

Dim par As String
par="^([0-9a-zA-Z]([-\.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$"
If Regex.IsMatch(txtEMAIL.Text, par) Then
 'do nothing and continue'
Else
 Form6.Show()
 Form6.Label1.Text = "You must enter a proper Email Address"
End If

After scratching my head and staring at it for a bit.  Figured it out.  Need to verify a proper email is entered before continuing.

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim par As String
        par = "^([0-9a-zA-Z]([-\.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$"
        If Regex.IsMatch(txtEMAIL.Text, par) Then
            If txtFULLNAME.Text = "" Then
                Form6.Show()
                Form6.Label1.Text = "You must enter your Full Name"
            ElseIf txtEMAIL.Text = "" Then
                Form6.Show()
                Form6.Label1.Text = "You must enter your Email Address"
            Else
                Form5.Show()
                Form2.txtFULLNAME.Text = txtFULLNAME.Text
                Form3.txtFULLNAME.Text = txtFULLNAME.Text
                Form4.txtFULLNAME.Text = txtFULLNAME.Text
                Form5.txtFULLNAME.Text = txtFULLNAME.Text
                Form2.txtEMAIL.Text = txtEMAIL.Text
                Form3.txtEMAIL.Text = txtEMAIL.Text
                Form4.txtEMAIL.Text = txtEMAIL.Text
                Me.Hide()

            End If
        Else
            Form6.Show()
            Form6.Label1.Text = "You must enter a proper Email Address"
        End If


    End Sub
