Que deixe, aqui está o código que estou a usar.

If Not IsNumeric(e.KeyChar) Then
           ToolTip1.Show("Campo Obrigatório, só números.", sender, 5000)
           e.KeyChar = Nothing
       End If

Eu estava a testar com isto até mas nada dá resultado..

Dim allowedChars As String = "-"
       If Not IsNumeric(e.KeyChar) Then
           ToolTip1.Show("Campo Obrigatório, só números.", sender, 5000)
           e.KeyChar = Nothing
       ElseIf allowedChars.IndexOf(e.KeyChar) = 0 Then
           e.Handled = True
       End If

Já descobri, assim funciona !

Dim lala As String = "-"
       If Not IsNumeric(e.KeyChar) And e.KeyChar <> lala Then
           ToolTip1.Show("Campo Obrigatório, só números.", sender, 5000)
           e.KeyChar = Nothing
       End If

Obrigado na mesma pela ajuda, tópico resolvido !
