pdfdoc.tryLock()

[Siddharth Shah]

when trying to save the document, I do a tryLock()... but it always returns me false. What can be the reason?

If tryLock failed, it sounds like some thread already holds a read lock on the document.  You can find further advice for locking at:

Yeah I read that... and now I am first doing pdfViewControl.docLock(true);

and then trying lock ... is this good?

pdfViewControl.docLock(true) is canceling any threads the viewer launched (such as rendering and find text), and then locks it for read/write.

If you call doc.Lock on the same thread, then that would be fine, though you don't need to (on the same thread).

Any other threads would be locked out though.
