Supondo que sou muito burro, o que e uma expressao regular?

A parte para verificar se a textbox tem um "@" ja fiz, a parte de permitir so numeros tambem mas fiz assim:

If Asc(e.KeyChar) < 48 Or Asc(e.KeyChar) > 57 Then
            e.Handled = True
        Else
            e.Handled = False
        End If

e isto nao me deixa usar o backspace, o que eu gostava de resolver...
