Check text box string format

[udik]

I have a text box that should be in a format of ##X## or ###X### or ##X###.
#- is a letter (number from 0-9).

how do I chek (in code) that the above will be the only possible string format and user don't use other format.

Thanks

You could set up an input mask and force the issue...

How to do it

Look in the properties of the text field and look for "input mask"... run the wizard if necessary.
