well first of all this newsgroup is for Help Authoring, meaning the Help files
associated with an application.

Try to use "IsNumeric" or regular expressions to check your input.

IfNumeric(Me.txtNumber.Text) = False Then
   MessageBox.Show("No number.")
endif

Download a example to provide ErrorProviders in your programm from:

a appendix to my post from this morning:

Private Sub txtPhone_KeyPress(ByVal sender As _
Object, ByVal e As _
System.Windows.Forms.KeyPressEventArgs) _
Handles txtPhone.KeyPress
Select Case Asc(e.KeyChar.ToString)
   Case Is < Asc("0")
      e.Handled() = True
   Case Is > Asc("9")
      e.Handled() = True
   Case Else
      e.Handled() = False
   End Select
End Sub
