• Smart Device Development Blank Values

  What is the best way to handle blank values in columns in database tables, that are not strings such as Date, Double, Single etc.. The dataset designer will only allow you to set throwException as a valid argument. I am copying records from Paradox tables that can have blank values in such fields. There are two places I am trying to fix this in my code. My limited knowledge of C# is not helping. DataSet1 . HorseJoinTableDataTable dt2 = new DataSet1 . HorseJoinTableDataTable (); //DataSet1TableAdapters.HORSETableAdapter ta2 = new FBWinMobileSync.DataSet1TableAdapters.HORSETableAdapter(); DataSet1TableAdapters.

• Visual C# Creating an Event and passing an object?

  I don't really know C#, I work in Visual basic. However I am trying to add some code to a dll written in C#. I would like to raise an event and send an object with it... not sure if thats the right terminology or not. while ((msg = Server.ReadMessage()) != null) { event_raising_code(msg); //help } This way in Visual basic I can setup an event handler to run things when i get a message, and at the same time get the msg object over into visual basic to dissect.

• Game Technologies: DirectX, XNA, XACT, etc. Possible to play mp3/other formats? Also FFT?

  Hello everyone, my first post here. From what I can tell it looks like XNA relies on XACT for audio, which only supports ADPCM at the moment.  A preliminary googling reveals that it's not all that great of a format for music, and wouldn't allow users to load tracks from their own mp3 collections.  Is there something better in the works for the final version of XNA (or is there another way of achieving this functionality)   Also, I was wondering if there is any planned FFT functionality to help with things like synching animations to the music. I ask all this because I'm looking at using alternative, FMOD, which supports a bunch of different formats and features (including FFT), and is compatible with man ...Show All

• SQL Server Cannot connect to localhost using Windows Security Group as login

  I have a test environment set up at home with a small windows server 2003 Active Directory domain. I created a windows security group on the dc and added myself and another user to the group. I then use this group as a login for SQL Server and add the login to the sysadmin server role.

• Visual Studio Team System Load test - "Avg. Connection Wait Time" counter

  Hi there, Do I need the "Avg. Connection Wait Time" counter on LoadTest:Request when executing a load test using one machine (Computer). This counter is added by default to the Load test, if yes how can I locate the Dependent Computer property, as this is blank I'm not sure why you're wanting to delete this counter, but I'm guessing that you're seeing a threshold violation regarding the "Avg. Connection Wait Time" counter. By default, a threshold rule is applied to the "Ave Connection Wait Time" to alert you that you may want to increase you connection pool size or change to connection per user. If you want to change the threshold rule, you can find the threshold rule u ...Show All
