I'm trying to insert Username, Password, and Account Balance data into my SQL Database. The code debugs correctly, but when I run the program, I'm not able to use the information I registered with to login with. (I have a separate form that lets me login with a username and password, and that works fine, so it has to be something to do with my register form.) Was this enough information?

Code:
Imports System.Data.SqlClient
Public Class register
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If TextBox1.Text = "" Or TextBox2.Text = "" Or TextBox3.Text = "" Then
            MsgBox("Please enter text into *all* text boxes.")
        Else
            Dim conn As New SqlConnection
            Dim comm As New SqlCommand
            Dim adapter As New SqlDataAdapter
            Dim ds As New DataSet

            conn.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database1.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
            comm.CommandText = "INSERT INTO users (username,password,balance) VALUES (" & TextBox1.Text & "," & TextBox2.Text & "," & TextBox3.Text & ")"
            conn.Open()
            MsgBox("Registered!")
        End If
        Me.Close()
    End Sub
End Class
