    Dynamically size a table

    I will need to monitor a queue with this project. Items can be added to and removed from the queue. I'd like the table to hold exactly these items, no more, no less.
    There are different ways to change the subscribed data on a client.

    The simplest way is to subscribe each item with a different table.
    With the .NET client you can do this using LSClient's SubscribeItems method (passing to it a single ExtendedTableInfo object) that will return an array of SubscribedTableKey (one SubscribedTableKey instance per each item contained in the ExtendedTableInfo ).
    You can then use the unsubscribeTable method to remove a single item from the subscribed ones or reissue a SubscribeItems to add new items.

    Please let me know if this approach does not fit your needs.

    If I understand correctly, this approach will subscibe to items already existing in the backend. But what if the backend changes?

    To elaborate: I am monitoring a phone queue. The queue can be empty or there can be multiple items in it. When the queue is empty, the frontend should not show any items. When there is a queue waiting, it should show all the items in the queue. As the queue can grow infinately (theoretically), I am not able to predict how many items I should subscribe to.

    Is there any way to get extended information over the open connection, like how many items there are in the queue, so the table can grow to that size?

    Thanks again!
    Kind regards,

    EriOor, probably what you need is the COMMAND mode. Please take a look to these threads:
