Run Spell Check In Access On One Field In A Form
If you want to automatically run the spell checker in an Access form, put this VBA code in the on exit event. It has to be in the on exit event, not the on change event, as you will get error messages if you put it in the on change event. Putting it in the on change event creates an endless loop, as the spell checker changing your spelling will then trigger the on change event again.
In this example, the field we are spell checking is called "comments".
If Len(.Value) > 0 Then
.SelStart = 1
.SelLength = Len(.Value)
.SelLength = 0
NOTE: the docmd.setwarnings is there so that you don't get the "spell check complete" popup message box that normally would come up when the spell checker runs. That message is nice when the spell checker actually finds a misspelled word, but you normally would get that same message when the spell checker runs and doesn't find any errors. So in this case we preferred to supress it.
