• Game Technologies: DirectX, XNA, XACT, etc. Any scripting support?

  I haven't found any info on scripting support in XNA. And the disccussion on supported languages seems to mean only C# is usable with XNA. So we cannot incorporate any script engine What about the DynamicMethod class As written in another thread the necessary methods are currently not supported on the XBox 360 version of the framework yet. ...Show All

• SQL Server Executing SSIS packages in order

  Project => New SSIS package => Execute package task and in this many more Execute package task with connectors. When we execute the master package how it will decide which is the first package. Hi Murli, You can connect n number of Execute package task with each other sequentially or parallely by connecting them in the control flow. Just make another package which will be your master package and add your execute package task on the control flow of the master package. Connect the tasks in sequence you want them to run.

• .NET Development Delayed send with smtpclient in .net 2.0

  Is there any way to force the smtpclient to send mail immediately with the .send method in system.net.mail 2.0 Right now it takes anywhere from 90 secods to two minutes before the mail is actually sent once the .send method executes. I've tried setting the object to nothing immediately after the .send method call, but no luck. The real issue for me is the send delay is also causing the smtpclient  to hold a lock on attached files that are being sent for that same 90 seconds to two minutes. I need to move the file immediately after emailing it, and right I get an exception telling me two processes can't access the file at the same time - obviously the smtpclient holding onto the file until it's ready to sent it. BTW, this app was usi ...Show All

• Visual Studio 2008 (Pre-release) Cider support for local assembly references?

  Am I doing something wrong Or do i possibly have an bad interaction between Cider and ReSharper (my guess). every time i make a reference to the local namespace in the same assembly... e.g. < Page x:Class = " MyNameSpace .TestPage " xmlns = http://schemas.microsoft.com/winfx/2006/xaml/presentation xmlns:x = http://schemas.microsoft.com/winfx/2006/xaml xmlns:local = " clr-namespace:MyNameSpace " Title = " TestPage " > < Page.Resources > < local:MyConverter x:Key = " myConverter " /> I end up getting all sorts of errors, even though it all compiles fine. In just the snippet i've pasted here, I get three errors: Assembly '' was not found. Th ...Show All

• SQL Server join several fields to create new field

  What would be the recommendation/approach in creating a seperate field in which joins several differate fields together. I have a table with field name a, b, and c. I want the information in those fields to be populated in a seperate field, d. So instead of: a 122 b joe c st I would have: d 122 joe st Thanks! Possibley a better way of doing this is in the view because I don't need to store the actual data. I just need a way to present it in an application. So if there's a sql statement that I could add to my existing view, that would work as well. One caveaet in the current view is that I still want the a,b,c fields to present themselves in the view. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Using own data-exporter.

  Hi, we are a team of programmers and graphic artists, wo work on a kind of an instant messaging system in 3D. We use C# and managed directx and are in a decision process, if we shall develope our system for XBox 360, too. Because we work on a commercial project, we have no time to wait for the content managment system. We must work and decide now. Indeed we need a kind of a content system and want to develope our own system with collada as intermediate format and some own formats, which will be only a image of the data, we will hold in the memory after loading, so that the loading process will be very fast - perfect for streaming data in the background. Will it be possible to load our models with the storage system on the XBox 360 Will it ...Show All

• Visual Basic Efficient programming of repeating tasks. Possible?

  Dear all, I have a form with picturebox (picInput1) and a number (say, 20) of radiobuttons rbLut1...rbLut20 that, when clicked, will impose 20 different LookUpTables (LUTs, or palettes) onto that picturebox. Luts are derived from other picture boxes that exist: lut0....Lut20. What I made (see below) works but it is typing-inefficient AND I don't like it because it is not elegant: '***Start current code:------------------------------------------------------- Private fyCurrentLut As String = "Lut1" Public Sub rbLut0_CheckedChanged(ByVal sender As Object, ByVal e As _ System.EventArgs) Handles rbLut0.CheckedChanged, rbLut1.CheckedChanged, _ rbLut2.CheckedChanged, ............ rbLut20.CheckedChanged 'KJ aug 2006.

• Visual Studio 2008 (Pre-release) RTSP streaming

  I've written a RTSP streaming server that streams live television by saving a .ts buffer file and then stream it using the RTSP protocol. However, when I try to watch the stream with a MediaElement or even WMP 10 or 11 it's just black, or it says that it doesn't support the protocol. So my question is, isn't there any support in the MediaElement for RTSP streams Not sure who the manufacturer is here... they should provide you a DShow filter to enable playback in WMP (and likewise it should work in WPF then). ...Show All

• Visual C++ C++/CLI C++ Interop and FxCop/Code-Analysis warning CA2122

  I've purposely been ignoring a CA2122 warning in some C++ interop code I've been working on for quite some time.  I've just recently had the cycles to investigate the warning  The warning message is as follows Warning CA2122 : Microsoft.Security : MyClass.Method():Void calls into Marshal.GetExceptionPointers():IntPtr which has a LinkDemand.

• Visual C# toolStrip with Database connection

  i have a combobox on my toolStrip How can I populate with data from a database ok i see, its different to what I thought it would be.

Then...   theSQLCommand.Connection.Open() SqlDataReader theReader = theSQLCommand.ExecuteReader(CommandBehaviour.CloseConnection); while (theReader.Read()) {    theToolStripComboBox.Items.Add(theReader.GetValue(0)); } theSQLCommand.Connection.Close();   &nb ...Show All
