Do until loop bogging down cpu help? Please?

[david]

I am using a do until loop to wait for a file to be generating before my code
executes the following task. Is there anyway to lower the amount of cpu
% the loop uses while the procees that generates the file executes?

Thanks

David,
Put a call to System.Threading.Sleep in side of your loop to temporarily
suspend the current thread. Consider starting with 500 ms to start (half a
second).

Another option is rather than use a hard loop which is rarely good in a
multiple process system as you are finding out. Use a System.Threading.Mutex
to cause the one job to wait until the other process says that the file is
generated. This is very CPU friendly. The Mutex constructor that accepts a
string can be used for cross-process communication...

Hope this helps
Jay

If you are waiting on a file to be created or changed use the FileWatcher
object and it will raise an event when the file is created, modified or
changed. Works great!
