• Visual Studio 2008 (Pre-release) June CTP - Possible Bug in XmlSerializer formatting process?

  The XmlSerializer format may be producing incorrect soap body. The crux of the problem is that arguments in an operation contract are being serialized in incorrect namespace. If the service contract namespace is different from those of types used in the operation contract, the arguments are being serialized in the service contract namespace not in their type namespaces. This problem manifested itself when I implemented the IXmlSerializer interface on the types used in operation contract. The following examplec code only uses the XmlSerializer attributes (i.e. no implementation of IXmlSerializer interface) to reproduce this problem: 1) Create following service contract [ServiceContract(Namespace = "http://mycompany.services.customer& ...Show All

• Visual Studio 2008 (Pre-release) DataType specific DataTemplates for XML data

  Hi everybody. I am trying to bind data from a XML file to a control using custom DataTemplates for various different XML elements (different tags). The problem is, that the DataTemplates are not applied to the the XML elements of the tag name specified in the DataType attribute. Below you will find some XAML code. Most of it is from the CompositeCollection SDK sample. I mimimalized and changed it to illustrate only the problem of interest. Desired behaviour: Jason , Hercules , Bellerophon (Hero tag) should be displayed in cyan Theseus , Odysseus , Perseus (Hero2 tag) should be displayed in blue However, it simply doesn't work. (I am using the latest September 2006 CTP.) You can reproduce the problem simply by star ...Show All

• Visual Studio Team System How to migrate a TeamProject for .NET 2.0 to .NET 3.0 ?

  Hello! I have a TeamProject that has been created with VS 2005 and .NET 2.0. If I install now the .NET 3.0 extensions for VS 2005, will it be possible to use the .NET 3.0 features like WCF And after installing .NET 3.0 extensions will the TeamProject automatically become a .NET 3.0 application Or do I have to install the .NET 3.0 extensions for VS 2005 ***BEFORE*** I create the TeamProject in order to use WCF Best regards CSharpNewbie22 The Team Project in TFS has does not really have much to do with the implementation technology.

• Game Technologies: DirectX, XNA, XACT, etc. A Simple 2D Map Editor

  I've built a simple XNA 2D map editor for fun that mixes xna and winforms. It supports 20 layers, multiframe and animating textures, and has grid snap. It's very basic and small, intended mainly as a learning experience. Grab here: http://webpages.charter.net/kharza/WorldWalker.zip Enjoy! Kenneth Thanks for the suggestions! Feel free to put it on your site if you wish. I didn't even think about the layer's scrolling differently. That seems like a no brainer. I was thinking in top down ultima mode. The flickering sprite shows which placed sprite is selected in the layer editor. With the layer editor you can change the values for the individual sprites placed down, or delete them.

• SQL Server SQL Server Configuration Manager to change run as account

  Hi, For the past few days i have been stumped on this problem. Our environment is the following: Windows 2003 R2 64 bit  SQL 2005 SP1 64 bit active/active cluster with several instances. Right now all instances use the same domain account to log on. For security reasons i wanted to assign a domain account for each instance to use.

• SQL Server sql server lockup after strange error in log, help please.

  Can anyone help me solve why my server is locking up. We're running sql server 2005 ent on a 2 cpu dual core server. With 3gig. Once each the last couple weeks, the machine has hung and the only thing I can find that's suspicious is on the sql server log.  It's below.  After the excerpt is about 50 more different memory errors.  As far as I know there's no ssl configured for log in, it mostly uses private lan cards for security between it and the web/application server. 05/31/2006 14:39:48,spid2s,Unknown,MEMORYCLERK_SQLQUERYEXEC (Total) <nl/> VM Reserved = 0 KB <nl/> VM Committed = 0 KB <nl/> AWE Allocated = 0 KB <nl/> SM Reserved = 0 KB <nl/> SM Committe ...Show All

• Visual Studio Team System Merge Conflicts for Identical Files ..

  When merging between two branches, TFVC displays merge conflicts ("The source and target both have changes") even when the file contents are identical. This probably results from the fact that the changeset numbers are different between the two files. Similar "false" warning show up in massive numbers (for large projects) during a baseless merge (probably due to changeset number difference as well). Is there a way from the IDE or command line to ignore these "false" warnings If not, is it possible to write a program using the object model to obtain a list of files which have "true" changes, and only manually merge those file The identical files could be merged with "AcceptTheirs" option, ...Show All

I've been trying to make a website for our customers to sign into where they can view specific details relating to their company (their product purchases, warranty end dates, and points balance tracking).

All I got so far is the actual layout and log in working. Now i need the backbone of the website; the database functions. Thank you.
