what i want is to put a range in the textboxes like 1-100 and will not accept if it is greater than 100
or a negative number...

hoping for your response...

its simple
use the following code on textbox lostfocus event

If Val(Text1.Text) > 100 Then
MsgBox "Invalid "
End If


In Property pages of Text1 .. MaxLength = 3
write this code, in Validate Event of textbox

Private Sub Text1_Validate(Cancel As Boolean)
    If Val(Text1.Text) > 0 And Val(Text1.Text) <=100 Then
        Cancel = True
    End If
End Sub


If you just want the number entered...use a NumericUpDown control, it will allow you to set a valid range of values
