Hello
Does anyone know the code to only allow certain chacters to be inputted into a textbox. Exmaple: The user can only put 1 letter in a textbox, the only letters allowed are I, S, E, R
As on a previous thread, im not looking to use a combobox as the design of the project specifically only allows textboxes (this is by my own design choice)
cheers
