Help with a VB Program

My code

Code:

Public Class Beep

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        System.Console.Beep(TextBox1.Text, TextBox2.Text)
    End Sub

    Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click

    End Sub

    Private Sub Label2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label2.Click
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Enabled = True
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Timer1.Enabled = False
    End Sub

    Private Sub Label3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Me.Hide()
        ShowInTaskbar = False
    End Sub

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

    End Sub
End Class

Now the problem is I want to add it so textbox 1 is 37 to 32767 and if anything else besides these numbers are entered it will popup a message saying "Error: Enter a number between 37 and 32767 for Hz"

Right now if I enter in a number like 36 it will cause an exception error.

Also I would like to set for texbox2 the max is 900 and if you go over it it will say "Error: Enter a number below 901"

Thanks for the help

 

have you tried to put a maxlength into your textbox? When it comes to minvalues's you could code it before submission and along with a requiredfieldvalidator check that if the length doesn't equal something greater than your min value, do not proceed.

I don't know where you are getting the exception rule but you can also code a Try/Catch/Finally $.02

Basing the validation on web forms programming and not windows.
