• .NET Development How to Create XmlElement Proxies?

  Hi all, I have a collection of XML documents identified by ids. The documents contain elements that refer to other documents by their ids. In other words, the XML documents are like a graph of XML data. Various views are used to display different parts of that graph using XSLT. The views should pull the necessary XML from the corresponding documents. For that means, I would like to instantiated proxies for thoses XmlElements which refer to XML documents. The referred XML documents should be loaded only when the view actualy is interested in their content, i.e. pulls out their content. What methods and properties of XmlElement must be overridden in order to achive such a behaviour I guess that ChildNodes must be overridden. What else Has an ...Show All

• Software Development for Windows Vista ASP.NET and Sequential Workflows

  Hi All, The subject of today: figuring out how to determine what kind of WF to use given a web-based context. Jon Flanders wrote an excellent example on using WF to drive a web app . Dave Green wrote a seminal article on how to determine which type of flow to use . Jon writes that " state-machine is really more appropriate for this scenario" where his scenario is a generic web application. I can see the point as the user is always more or less in control using a browser (you can close your browser, hit back, jump to an unrelated link etc etc). The way I read his post is that inherently in a web app you are somewhere in a particular state and the various links/buttons you see would translate to the various actions (and the ...Show All

• .NET Development Reading data from networkstream

• Software Development for Windows Vista Designer And debugger Issues.

  Hi, I was wondering whether anyone is suffering problems with WF in VS2005. I've been really frustrated by the designer, it constantly moves around the shapes in a workflow design to really awkward positions which means i'm having to move them back again to view it properly and a major problem i'm haing now is that states just become invisible!!! the connectors are still going to them but its just an empty space. i have to restart studio sometimes 3 or four times. today i'm at breaking point as a workflow i've been working on has now 2 states that are invisible but i cant get them back..... deadlines everywhere i'm really thinking of packing WF in now and waiting until a service pack or something. i mean how hard is it to write a des ...Show All

• SQL Server date parameter issue

  hi all We are a multi site / multi language company so do not want to hardcode the date format - these reports will be on intranet Using MS Sql - Reporting Services 2005 Using no formatting on fields = yyyy-mm-dd - is how it is displayed. I added a @startdate and an @enddate parameter I read up and saw this information: Report properties set 'Language' setting to '=User!Language' to detect user culture automatically My regional settings are set to English (New Zealand) but whatever I do I receive no data - (data is definately there eg when run without parameters) so it is obviously the dates incorrect. Can someone give me some advice on what else to check. Looks like you have ...Show All

• .NET Development Connection pooling for SSAS using COM+ is not working properly.

  Hi, can anybody help   I tried using COM+ (servicedcomponent) for pooling connections of Analysis Services 2005 (SSAS). It seems that COM+ is establishing connections as per the object pooling attribute shown in the code below. When the client create instance of this class it gets assigned with already created object and gets a connection to SSAS. After firing MDX query using that connection, the client disposes the COM+ object, which should return the Connection to the pool for reuse but I saw in the Profiler that it logs off (close) the connection. If I create connections to SQL Server 2005 it works perfectly i.e. once the client disposes the COM+ object it returns the connection to the pool and next request automatically us ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Xbox libraries/.net

  While I'm intrigued with running stuff on the xbox, I am wondering how much apart from XNA will be available "as standard" with it - inparticular, what from the .net framework survives(presumably some version of the compact framework ), what will be replaced, and what will need to be rewritten..  (Things are much easier on the PC) For example, if I want to add System.Drawing to modify textures (or something more windows dependant) and tell it to copy local.. what would happen...  Or more importantly, how can I highlight what will and won't work   ...or is it hit and miss/wait and see Hopefully this will be well documented at the time of release but for now the best advice is: ...Show All

• Visual Studio 2008 (Pre-release) Inactivity timeout : "The message contains an invalid or expired security context token".

  Hi, I'm having the same issues with expired tokens that is described here : http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=278806&SiteID=1 The config in that posting shows how to set it for a custom binding, but I would like to set it for wsFederationHttpBinding and/or wsHttpBinding*. * Will I need to specify it on the STS only or on both the STS and the actual service Thanks You can't set those values directly on the wsFederationHttpBinding or wsHttpBinding. That's what CustomBinding is for - to have greater control over the binding element collection and all of their respective settings. To simplify things for the average bear, all of the standard bindings assume certain d ...Show All

• .NET Development Static methods behind the scene

  How static methods work inside CLR Is it similar to the old C++ architecture with a single copy of the method for all instances How member functions work/represented inside CLR Yes, static methods belongs to type, not to instance. And they are located in another then instance methods, let's say, "table" inside the CLR. For each class there is a "Type-object" inside the CLR. This object contains all the information about the type and all the static methods are located in it. For each instance CLR creates an "instance-object" which contains instance related data (properties, methods) and the reference to the "Type-object". You can read Jeffrey Richter's book ...Show All

• Visual Basic How to Find last record in a database

  How can I find the last record (row) in a database I am developing a VB 2005 program that must read a sql database and find the last record so I can retrieve the last "Batch Number" used. This will then be incremented and the new "Batch" record will be inserted into the database. I can't find a SQL command that will work except to read each record until the EOF. Can this be done Thanks, Ron Do a simple select max(BatchNumber) from <TableName> http://www.sql-tutorial.net/SQL-MAX.asp   which will give you the highest batchnumber. Or simply use a identity field which will automatically increment the number - you can then retrieve the @@identity value when you ...Show All
