I'm getting the following exception in certain situations when using my custom parts editor

I've uploaded a sample program that shows the issue here

Placing the cursor at the beginning of the first octect ( 101 ) and hitting the Delete ( not the Backspace ) key will throw the exception.

I'm downloading the latest build of Actipro but if there's a fix for this using 10.2.532 that would be preferable since otherwise I'll have to retest everyplace where I use Actipro controls.

Just tried with 11.1.540 and it had the same behavior.

Is there any way that I can address this issue in 10.2.532 by making changes in my code?

Hi John,

You can try altering your regex to allow "01" (or "001" or "024"). That would probably just get translated to "1" and avoid the underlying issue.

Thanks, that appears to have worked.
The latest build of this product (v24.1.1) was released 1 month ago, which was after the last post in this thread.
