>Is it possible to, using the format property to limit the input into a textbox? For instance Only three letters - a Y for Yes, an N for No, and an M for Maybe - and have it not lose focus if one of those are not entered. I know how to do it in the Valid method, but was wondering if there was some magic to use in the Format property, or something

Hi John:

You can use Bill's method with inputmask or you can use a combobox with this 3 options too, so only this letters can be selected and the focus is not lost until you press TAB, ENTER or click on another control.
