You could use a regular expression to do it, but the easiest would be just simply use IsNumeric()

well if your using a textbox then you could go,

VB Code:

Private Sub Text1_KeyPress(KeyAscii As Integer)
 
    If Not (KeyAscii < 48 Or KeyAscii > 57) Then
        KeyAscii = 0
    End If
 
End Sub

for no numeric values to be entered and remove the NOT for vice versa
