Public Class Form10       Private Sub Form10_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)  Handles MyBase.Load        'Here TextBox is masked as number show you can enter number only         MaskedTextBox1.Mask = "00000000000000000"     End Sub       Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)  Handles Button1.Click         'Enter number will show in Label         Label2.Text = "Entered Number is  " + MaskedTextBox1.Text     End SubEnd Class

When you enter other than number then masketextbox will not accept.Because in code mask is specified as MaskedTextBox1.Mask = "00000000000000000" which means it will accept only number.
