On Text Box Key Press event procedure write

if Not Instr(1,"123456 7890",chr$(KeyA scii,0) > 0 or KeyAscii = 8) then
KeyAscii=0

Re: TextBox numerical values

I am not sure the NumericUpDown list is what I am looking for,

as what I have is a simple Textbox, and I just want to ensure that only
numbers are entered, (later they are picked up by a formula)

on further research i have found
TextBox1.Numeri c = true

for VB

so maybe there is an equivalent for VB .net?

Hello, rodger:

You may find useful the sample for the TextChanged event for the textbox:
