• Visual C# Indexers vs Get.Set methods

  I have a class called statTable. It collects and computes a large number of statistics for a variable. One of its members is a list of ints called frequencyCounts. The statTable's constructor defines a set of intervals over the range of the variable being tracked. Every time statTable's Update() method is called with a new value of the variable the frequencyCount corresponding to the interval for that value of the variable is incremented by 1. In addition to the frequency count there are several statistics based upon frequency that the user of a statTable could be interested in accessing. For example, percent, cumulative frequency, cumulative percent. I see three different ways to design my statTable class to provide these statistics to th ...Show All

• .NET Development Optimizing performance when enqueuing and dequeuing data

  In an application I have the need to enqueue data from one thread while simultaneously dequeuing it from another thread. I have already implemented it using the Collections::Queue class but I am experiencing performance problems, which I believe are caused by the constant allocation of memory on the managed heap (when enqueueing) and deallocation by the garbage collector (occasionally when dequeuing). I currently have around 1200 enqueues and dequeues per second (around 6 of each every 5 ms) but I sometimes see glitches of up to 20-30 milliseconds between enqueues (and that's with an asymmetric process - the dequeues are of lower priority than the enqueues). My current approach is as expected - I allocate an object, store data in it, an ...Show All

• Visual Studio 2008 (Pre-release) June CTP: A datacontract based schema is being created even though type is implementing IXmlSerializable

  Hi, I have some data types that implement IXmlSerializable and I want to continue using them along with WCF. What I noticed was that WCF was calling the GetSchema() method on the data type and also displaying a corresponding "service.svc xsd=xsd x " schema, but at the same time also created a new definition of the same type in the " http://schemas.datacontract.org/2004/07/... " namespace and is using that instead of the schema returned by GetSchema(). ...Service.svc xsd=xsd0: ... < xs:import schemaLocation = " http://rkulkarnixp2.jda.corp.local/WCFServiceLibrary/Service.svc xsd=xsd2 " namespace = " http://schemas.datacontract.org/2004/07/ClassLibrary " /> < xs:import schemaLocation = " http://rkulka ...Show All

• Windows Forms DatagridviewCell PointToScreen

  Hello. I want to display a window form underneath a datagridview cell as a pop up box. I need to find out the location in screen cordinates where the datagridviewcell is so I can display the winform there. However, my datagridview has a scrollbar, so I cant just simply take the datagridview point to screen and adjust width and height according to row position (I would need to know the scroll position num to offset row position). Is there an easy way to do what I want to do In VB 2005 I did: Dim _pointCell As Point = Me .OrderDetailDataGridView.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, True ).Location Dim _pointGrid As Point = OrderDetailDataGridView.Location Dim _pointLocation As Point _pointLoc ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DrawableGameComponent ContentManager Member ?

  I was happy to see a GraphicsDevice member in the DrawableGameComponent class. This saves me from getting it through the GameServiceManager, but mostly GameComponents which can draw itself should also be able to load it's graphic contents. I think it would be a good Idea to make the game's Contentmanager also a DrawableGameComponent member like the GraphicsDevice. Made already a feature request for that: https://connect.microsoft.com/feedback/ViewFeedback.aspx FeedbackID=244332&SiteID=226 How do you think abaout that I know that the content manager is for loading and that's the point...the GameComponents should be able to load it's specific content by themselves and don't let this do the main game clas ...Show All

• Visual C++ Problems Creating Win32 Console Visual C++ project template

  I've been trying to create a Win32 Project template for C++. I create an empty Win32 project, add a few files to it, save it all and when I go to the file menu to export it as a template I am not allowed to. I have Visual Studio 2005 Professional and I've tried doing similar things in both C# and VB and it works with those two languages. What I'm trying to do is set up a template for students to work off to create applications that work with ILOG CPLEX libraries. If anyone could shed some light as to why I cannot create a simple template it would be greatly appreciated. dj Hello Does this help: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=927381&SiteID=1 Tha ...Show All

• SQL Server Help please some data not replicating

  Hello, We have four mobile devices that are set up for merge replication via the web. We are not receiving errors but some of the data is not coming over to the devices. If we manually add a record that record will come over, but there is data that is on the server that isn't on the devices. If we run the snapshot for each device (We're using host_name as a filter) nothing happens. If we do validation check we get errors. If we reinitialize all devices it works but the next days data (sql job populates data to the publisher db at night) isn't on the device after syncing the next morning. Any help would be appreciated.

• SQL Server output parameter in CLR stored procedure written in C++

  How can I declare output parameter in stored procedure, written in C++/CLR In C# it is proc_name( out SqlInt32 value ). In VB.NET it is proc_name( <Out()> ByRef value As SqlInt32 ).

• SQL Server How to make a File Share Subscription running on Vista?

  I recently migrate to Vista.   I had a bunch of reports with file share subscriptions that were running fine on XP.   After installing reporting services on vista (that part only was a challenge), I re-created my subscriptions using the report manager.   As expected, when a subscription is executed, the ‘last run’ column shows the last time the report output has been delivered to the file share and the ‘status’ column shows ‘New Subscription’.   I thought that this was the signature of a successfully configured subscription.   But surprisingly, there is nothing in the file share. The directory is empty.   Anybody has an idea why   Anybody knows how I could possibly find information on my ...Show All
