RE: Dataqueue Help

Do you have a stack trace?  That will tell us if the Toolbox threw the
exception because of an internal problem or if the code processing the data
that comes back from the Toolbox object throws the exception.

What exception are you getting when the queue is empty?

-|Hello,
-|
-|I am using a while loop to read a dataqueue and am having a problem when
I
-|empty the queue of records. I keep getting an exception when the read()
is
-|executed after all other records have been read.
-|
-|Does anyone know where I could get an example of reading data queues in a
-|loop environment? The examples in the tool box manual show a "wait on the
-|queue" technique or just a straight read. How do you handle the
exception?
-|
-|Thanks in Advance!
