File Closed 1

[Killa]

Is there a way to see if a file has finished being written to?


Back Ground



I'm writing a program in visual basic to monitor a windows directory then process any files that appear there but it must ensure that the file has finished being written before proceeding


any help would be much appreciated

Attempt to call CreateFile in exclusive mode in a loop. If you succeed, the file is done being written to.

(you'll want to wait 250 milliseconds or so between checks so you don't hammer the system responsiveness)

chiph, thanks. I've been working on a different problem where I need to know when an application has finished working with a file. With Word and Access thats been easy, but with Excel, Powerpoint and Visio I've been stumped. Your solution is so simple and so obvious, too obvious that it did not even occur to me.

Thanks again and a star for your genius.
