Detecting "Cancel" on "Crop Pages" dialog

Post by plgoldman »

I have developed a very nice program which uses a combination of "cmd.document.cropPages," "op.document.extractPages," "op.document.insertPages," and ""op.document.deletePages" to extract a set of new documents from a large PDF document with the ability to use only a portion of a page in the original document as the first and / or last page of one of the newly created documents. The website documentation has been a tremendous aid in putting this all together but there is one condition I can't figure how to check.

How would I determine that an end user clicked on the "Cancel" button rather than the "OK" button on the "Crop Pages" dialog screen?

Thanks,
Paul

Hello Paul,

If the user clicks OK in the Crop Pages dialog, then the op.document.cropPages operation should take place afterwards.
Basically what you can do is to catch the https://sdkhelp.pdf-xchange.com/vi ... oreExecute event and see whether it's a Crop Pages operation. If so, then continue with your logic after the operation execution.

Cheers,
Alex
