InfoPath Dev

Hello. I'm new to these forums and to InfoPath, and I have a quick question.

 I'm trying to create an input form similar to a text message. I have a large textbox for the message, and I have a small textbox that is read-only that I want to show the character count.

I got this to work by setting the default value of the small textbook to the string length of the large textbox. This works correctly, but I would like to update the small textbox every time a character is entered into the large textbox, not every time I click off of the large textbox.

Any help would be much appreciated.

As per I know this can be done using KeyPress event - again, I am not sure how to invoke those events in InfoPath.

In general, InfoPath can only respond to events when a field's value is finished being modified.  You might be able to accomplish what you want using a custom ActiveX control.  I've never forayed into this area, and it's not for the faint of heart or inexperienced.

 you can use java script to achieve this, i would suggest using this path only if you know what you are doing.
