SqlDependency - Options and TimeoutI'm using SqlDependency quite a lot and really love it, but there are two things I just can't seem to find anywhere on MSDN or elsewhere. 1. One of the SqlDependency constructors, allows you to pass a "string options", which sounds great. But IntelliSense on this item is useless and just points to SqlNotificationInfo.Options which says nothing. I would be interested in knowing what to pass into that string and which format it has to have. 2. The reason I'm trying to find that out, is the time-out. I've read here (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/html/querynotification.asp) that I am informed if my dependency time-out. (Either using the server default or the value I passed to the constructor.) But it's not happening. I tested using the server default and a value of 10s. I just waited to see what happened and never got a notification. If I then changed the data (with the app still running) the app didn't get notified, because the dependency had already timed-out. Is this a bug or am doing something wrong? I really would appreciate any answers or suggestions! Thanks, Alex The options enumerations are described here:
http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlnotificationinfo.aspx If this doesn't help, let me know. Things have changed significantly since the article you refer to was written. --Mary Show quote On 16 Apr 2006 10:43:24 -0700, "Gidion" <alexander.duggl***@gmail.com> wrote: >Hi, > >I'm using SqlDependency quite a lot and really love it, but there are >two things I just can't seem to find anywhere on MSDN or elsewhere. > >1.
