• Software Development for Windows Vista Removing service subscriptions for non-guaranteed events?

  I'm writing a workflow service to watch for file changes, which implemented the following interface (note: correlation attributes not shown for clarity): [ExternalDataExchange] interface IFileSystemWatcher { event EventHandler<FileWatcherServiceEventArgs> FileSystemEvent; void Watch(string directory, string filter, WatcherChangeTypes changeTypes); } I have derived an activity from CallExternalMethodActivity to set the subscription up on the service by calling the Watch method (internally in the service this creates a FileSystemWatcher and stores it in a hashtable with other details about the subscription), and another from HandleExternalEventActivity to handle the FileSystemEvent event. It's all working fine, the events are ...Show All

• .NET Development Using FtpWebRequest in .NET 2.0 via C# - Occasionally get "Server committed protocol error"

  On doing an FTP file upload from the XP Embedded PC in our product to another internal embedded processor (which is connected via ethernet and is part of the product) we occasionally get an exception System.Net.WebException: The underlying connection was closed: The server committed a protocol violation ... at System.Net.FtpWebRequest.SyncRequestCallback(... The behavior I see on the wire when this happens is after we do a USER request we get "Response: 230 User \b\206B\240 logged in". This happens the first 2 times with 2 different (but consistent) "garbage" strings as user names. The third time and on succeeds and returns a space " " as the user name (we login as "(none)") . ...Show All

• SQL Server Suggestions for SQL 2005 Setup

  OK we currently have a single SQL 2000 Server for our DW with a DR SQL 2000 Server. We are wanting to create a setup where we have a Failover Cluster of SQL 2005 here at the main office with a DR SQL 2005 system at our DR site. My question is... How would you all do the failover and stuff How many servers would I need and what would be the job/role for each server. Some things to take note we are implimenting a SAN in our network and we are also implimenting a Virtual Server system on our network. To my understanding you do not really wish to run SQL Servers on a Virtual machine if possible. So I am already planning on making the SQL Servers Physical systems. We are also planning on putting the DB's on the SAN and have the SAN replicate a ...Show All

• Smart Device Development Button or image on today item

  Hi all, With the help of the sample project memwatcher, I have created my own today item (actually I removed everything from the project which was not neccesary and called it "my own" ).
