>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

This is technically obsoleted (a hangover from pre-VFP days) but it still works and it might do what you want
Set the format property = M (no quotes)
Make the inputmask property = Y,N,M (no quotes)

The user can key the desired result or scroll with the space bar, but nothing else can be entered
