• .NET Development Execute Stored Procedure (and access output params) without a data table ?

  Hi all, I'm just getting my head around the .NET Framework in this area so apologies if this question is dumb. All examples in help and books relating to running a stored procedure seem to involve a database and the fill method. There must be numerous circumstances where you simply want to pass parameters into a stored procedure and let the database do the work, then access the output params. Can I define and run a stored procedure without a datatable OK - Thanks very much Jeff, much clearer. How are the output parameters accessed after the call Is this via the parameters array ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Xbox360 Threads, just interested ...

  I know that the xbox has multi cores and can run several threads concurrently, how do you write for a particular core on the xbox 360, or will the CLR choose when to use another core. Or maybe our code will only run on 1, can someone please enlighten me. Hopefully, it will be as easy as this - Thread myThread = new Thread ( new ThreadStart (myProc)); myThread.SetApartmentState( ApartmentState .MTA) myThread.Start(); and the clr does all the hard work.

• Visual Studio Express Editions Need Help

  Hi, I have a "guide" who talks to you in my program. When you put your mouse over a button, it does this: Dim mw As New SpeechLib.SpVoice mw.Speak("My Websites", SpeechLib.SpeechVoiceSpeakFlags.SVSFDefault) talk.Text = "" But, it basically freezes the button until he is done talking. then, you can click it. I want to make it so, while he is talking, you can click the button. Thanks! sounds like its blocking your main thread until its finished. You may wish to check the SDK that you are using on making it do it in ASync level, otherwise you could spin up another thread and let it talk from there without your main thread (UI) from hanging however threading can ...Show All

• .NET Development Time zone conversion problems

  Hi, I'm trying to parse a date time string that is always in ET time zone. The resulting time should be converted to local time. I could do that by backadjusting the ET time and converting to UTC. However, the issue is that I don't know if ET is currently in DST or not, so that I don't know how many hours I have to backadjust. Is there a framework built in way to get the UTC offset for any time zone Thanks, Tom Maybe I expressed myself incorrectly. The file contains values that are stamped in ET. The problem is that the system doesn't know when Eastern changed to DST so that I can account for the DST change in the offset calculations. ...Show All

• Windows Forms Flicker using doublebuffer

  I created a UserControl which contains a Panel. I created an eventhandler for this Panel's Paint event. In this handler I draw a grid for the background and the a line which links to squares the user can move. Every time the squares are moved the panel is invalidated, in order to redraw the link. Repainting gives a lot of flicker. As in other controls I made, I tried to use doublebuffering in both ways, through SetStyle and the DoubleBufferd property. Flicker remains. I also tried to use one transparent panel over the panel with the grid. The grid needs to be painted only once, while the links are often repainted. So I tried to put squares and links in the transparent panel, but the grid panel is still repainted every time the transparent ...Show All

• Visual C# file.Read statement in NPlot.

  Background: I downloaded a graphics C# package NPlot from a website. It is freeware. I included the whole set of files (4 demos and a library + dll) into my project where I intend to use NPlot as a part of my application. After a few snags it easily compiled. A part of it is running lready, however, here is the situation I cannot resolve: <This code is part of PlotWave function in PlotSurface2DDemo.cs > System.IO.Stream file = Assembly.GetExecutingAssembly().GetManifestResourceStream("NPlotDemo.resources.light.wav"); System.Int16[] w = new short[5000]; byte[] a = new byte[10000]; file.Read( a, 0, 10000 ); I get an error at the last statement during runtime (debug): 'Use the "New" keyword ...Show All

• SQL Server MDX query with filter clause

  Hi, I have the following MDX query which is supposed to return the number of records with Actual time > TargetTime for each customer, location and editor. Actual Time and Target Time are measures on the Fact table defined in minutes and represented by integer values. The hierarchy I have created is Customer Name Location Name Editor Name The MDX query I have written is: Count ( filter ( Descendants ([DimCustomer].[Customer_Hierarchy]. CurrentMember ,[DimCustomer].[Customer_Hierarchy].[EditorName]), [Measures].[ActualTime]>[Measures].[TargetTime] )) But this query gives me the number of customers rather than the number of records with ActualTime > TargetTime for each customer, location, edit ...Show All

• Visual Studio Express Editions Gzipstream Question

  I've searched in the msdn database for gzipstream stuff. It's really good working but I haven't figured out how to unzip more than one file out of a gzip. GZipStream doesn't deal with an archive with files, just a stream of bytes. You'll need a lot more code to parse the contents of the archive. Rather than inventing this yourself, try a freeware Zip assembly such as SharpZipLib ... ...Show All
