• Game Technologies: DirectX, XNA, XACT, etc. Could C# be the future of gaming?

  Since XNA is using C#, and is is a more intuitive language than C++, is it possible that in the future that C# will dominate, espessially in AAA titles. Could XNA be ushering a new way of programming in the main stream Hi Jeff, As some one who is a partner in a company (and lead developer) that produces enterprise high performance security applications, many of them in C#, I think you will be very surprised what you can do with C#. I develop in C++, C++/CLI (.net C++) and C#. C# is my favorite by far. While it certainly takes a lot of care and research to get the "barn burning" speed you can truly get out of C#. Once you know what to avoid and how to write performance critical apps in C#, you will only go back when you ...Show All

• Visual Studio Express Editions Autocomplete Combobox

  I'd like to mimic Access's autocomplete combobox with the NotInList event. User can start typing and if the text exists it will appear... if it does not and user hits enter, an error messagebox "does not exist" is shown. Please can someone help direct me to a solution in C# Thanks for checking. I'm running this off a databound (from access mdb) combobox. I shut everything down and rechecked my code but I'm still getting the same error. ...Show All

• Software Development for Windows Vista Communicating a WorkflowAuthorizationException result from a web service call

  Hi I've already posted on this issue before but never got any answer that solved my problem. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=791955&SiteID=1 . Please have a look at this post to get some more background. My solution to getting an exception result back to the client is to allow the workflow to throw exceptions all the way up to the root of the workflow and terminate. The webservice activities will report this as a result of the call. I then, looking at another post, changed one of the SqlPersistenceService stored procedures slightly to not remove the instance from the InstanceState table for this type of termination of the workflow. Effectively throwing the in memory workflow instance away and maintaining ...Show All

• Audio and Video Development XPath - intersection of nodesets

  Is it possible to perform an intersection of nodesets within an XPath And if possible... Is there a somewhat elegant way to do it Seemingly it's not difficult with XPath 2.0, however with the HD spec we're using a subset of XPath 1.0. The most common reason anyone would want to do this -- since elements can have multiple classes, let's say we'd like to select all elements with class('a') AND class('b'). The class() function involves a built-in (which is probably optimized / indexed on DOM load) split() or tokenize() on the "class" attribute string, and it would be hard to mimic this ability looking at @class directly. I realized what the problem was -- this may (or may not) be instructive... I ha ...Show All

• Visual C# deleting network drives

  Is there a way to programmatically delete a network drive. I can get the network path and the drive name but can not seem to remove it. I can disconnect the the drive, but I need to be able to delete it from the system, so it no longer shows up in My Computer. This is how I'm getting the drive name and path: ManagementClass manager = new ManagementClass("Win32_LogicalDisk"); ManagementObjectCollection drives = manager.GetInstances(); foreach( ManagementObject drive in drives ) { if(drive["DriveType"].ToString() == "4") { System.Console.WriteLine( "Name=" + drive["Name"].ToString() + " Path=" + drive["ProviderName"].ToString()); } } Any idea how to delete ...Show All

• Visual Studio Project Item Templates

  Hi all, I'm developing a new project wizard which has to create both new projects and project items according to project and project item templates that we've created and tested. The problem I'm having is this: The new projects are being created correctly with the new template via (Solution2) GetProjectTemplate() but whenever I try to create the project item from its template via (Soluntion2) GetProjectItemTemplate() it throws the following exception: System.IO.FileNotFoundException Message: "The system cannot find the file specified.

• .NET Development Webservice consumes all the available bandwidth.

                   We are on the test phase of a windows-webservice-Oracle application.Clients would connect the webservice through VPN or VSAT. VPN users would directly connect with the webserver,where VSAT user will connect with the VSAT server which will be routed to the webserver. Now the VPN users have an average bandwidth of 512 kbps and VSAT users have an average of bandwidth 360 kbps.There would be an average of 30 users at a time whom would connect either through VSAT or VPN. Now,if we connect through VSAT environment it runs out of bandwidth.The transacted data may reach upto 1 MB for each user. The web server memory is 2GB.We haven't implemented cl ...Show All

• Visual Studio Team System What are the steps for Load testing using NUNIT testcases?

  Hello, I have installed Team Suite and i am trying for Load Testing using NUNIT Test Cases that we have prepared. What are the steps for Load testing using NUNIT testcases Do we have Cool Down Time in Team Suite If 'YES' How to set it Thanks, Riti You could just convert your NUNIT cases to VSTS unit tests using the NUnit converter here: http://blogs.msdn.com/jamesnewkirk/archive/2005/06/24/432485.aspx and use those in your load test No - there is no explicit "cooling time" in load tests really, but I assume what you want to do in the cool time is reduce number of users accessing the system gradually, right ...Show All

• Visual C# how to get total cpu usage

  I need to be able to get a "total cpu usage" snapshot (system wide, not just for the process). anybody have a point in the right direction   I see that the Process class has CpuTime usage, but returns a timespan object.  If i'm to use that, how'd I convert a timespan into a % usage Steve, your best bet is probably to use the System.Diagnostics.PerformanceCounter class. In your case: using System.Diagnostics; ... public class MyClass { PerformanceCounter counter = null; public float CpuUsage { get { if (counter == null) { counter = new PerformanceCounter ("Processor", "% Processor Time", "_Total"); } return (counter.NextValue ()); } } ...Show All

• Visual Studio 2008 (Pre-release) Web Service Implementation

  Hello, I am attempting to create an extremely basic "Hello World" web service using WCF. My service compiles fine and the wsdl is generated and I can browse to the wsdl via IE without any problems. I am now attempting to create a console application that calls this web service and simply display "Hello World" which is returned from the method. However, when my console application calls the service, it just hangs (providing I've set the Timeout to -1). Can someone please provide me with some direction I apologize if this is a dumb question. I just thought it was going to be quick and simple. Here is my code for the service: using System; using System.DirectoryServices; using System.ServiceModel; us ...Show All
