• Visual J# How to close a blocking DatagramSocket?

  Hi; I have a DatagramSocket that is waiting on a receive: DatagramPacket pkt = new DatagramPacket(new byte[100], 100); mySocket.receive(pkt); I need to close the socket when my application is ending (it is in a worker thread). I presently call mySocket.close() and that works but I get: net.windward.xmlreport.b: [formatter] ac.server WARN net.windward.xmlreport.b - direct java.net.SocketException: A blocking operation was interrupted by a call to WSACancelBlockingCall net.windward.xmlreport.b: [parser] ac.server WARN net.windward.xmlreport.b - multi java.net.SocketException: A blocking operation was interrupted by a call to WSACancelBlockingCall The thread 0x9d8 has exited with code 0 (0x0). net.windward.xmlreport.b: [p ...Show All

• SQL Server Filter SQL Server data by user With an Micmicrosoft access front end

  I am in the process of migrating 40 access databases to SQL Server and still use an access front end.All of these databases are Identical in structure and purpose. The goal is to centralize all of the databases backends into one Sql server database, but the data needs to stay seperated by each location(user). I was able to add a location feild to all of the tables to keep the data seperate. Then I imported three of the locations data for testing. I would like to know how could I filter the data on the access frontend, so that it would ask the user for their location and only allow the user to access, update, and delete that Locations data I need an example of how to do it on the access front end , and not the the sql server side.

• SQL Server trouble getting snapshot agent to initialize publication

  I have been trying to set up transactional replication between an OLTP SQL Server 2005 Standard edition server and a BI SQL Server 2005 Enterprise edition server. I am using a pull subscription. I was able to establish the replication from the developement server to the BI server however when I tried setting up the replication between the production environment and the BI server, using the same configuration settings, I ran into a problem. The production server had been renamed after it was initially set up. I used the sp_dropserver and sp_addserver to solve this issue and was able to run the replication wizard. However once the wizard finishes the snapshot agent doesn't initialize the publication. When I look at the replication monitor it ...Show All
