• Game Technologies: DirectX, XNA, XACT, etc. Using Static Members

  In my projects, instead of passing the GraphicsDeviceManager and the SpriteBatch by reference to the constructor of every class that will need them, or directly to every method that needs it, I prefer making them both Public Static Members of my main class, thus being available anywhere in the program. I would like to know, is this a bad solution And if so, why is that I understand one of the reasons is portability. If I passed them by reference, then I could re-use those classes in other applications without any change. But consider that I'm using these classes for my own application only, and if I needed to use it somewhere else, the changes to be made are still minimal. On the other hand, by using the Static approach, both classes and ...Show All

• Visual Studio 2008 (Pre-release) Does WCF support message encryption using short key?

  Can a Web Service with message security using less than 128-bit encryption key be implemented in WCF It seems that there is no System.ServiceModel.Security.SecurityAlgorithmSuite class with key length lower than 128-bit. In general, can you advise on the approach to developing a secure web service that can operate under strong encryption requirement in the US and a relaxed encryption abroad due to encryption export restriction Thanks!

• SQL Server File Metadata and the Foreach Loop Container

  Hello, I want to set up a Foreach loop container to loop through several flat files. I have a connection manager set up for individual flat files. The metadata for the files is all the same. They are fixed width files, and contain sixty five columns. I didn't see a place in the container properties to configure the metadata of the files. How can a Foreach Loop Container 'know' the metadata of the flat files that I want to loop through Thank you for your help! cdun2 I tried to implement this by following SSIS Tutorial Lesson 2 and the pkg only processed the last file in the list. From one I can tell from the project log, it didn't even loop through the other files, though it did process the las ...Show All

• Software Development for Windows Vista SequenceActivity inheritance

  Hi! I have a few custom activities which all inherit from my base class which inherits from sequenceactivity. Is is possible to use the designer in both my base class and the other custom activities Specificaly, I would like to add a ifelse to my base class which should be run after the flows that inherit from this base class have completed. Is this possible Thanks for your help! Once you add built in children to a custom activity or base workflow, one you intend on deriving from, it becomes locked. This means no more children can be added. One way to get around this is to have a custom toolbox item that adds the child when the activity is added to the workflow, see this post for info.

• SQL Server Parent Child Relationship

  I created a parent child relationship in SA 2005. It works great, except when adding it to the cube and browsing it. It shows the ID instead of the Name attribute. How do I make it show the name attribute Thanks in advance, Mardo Suppose you have the following columns in your table: ID - Integer. Primary key column of your table ParentID - Integer. The id of the parent object. Name - String. The name of the object identified by ID. Since things already work for you then you already have the key attribute and parent attribute set in your dimension.

• Visual Studio Team System Team Build producing PDB files despite Release Mode Configuration Build

  Hi All, I have a Web Application Project built with Web Deployment Project and another web service project being built via Team Build. How come when building in Release mode there are pdb's still generated for some projects and not for all My WAP or Web Service projects generates a PDB. I don't really understand this logic. It shouldn't do that. Cheers mike The build configuration of web applications is NOT defined by the build configuration, it is defined by the debug attribute of the compile element in web.config. The reason for this is that web applications are typically compiled at run-time when the application is first accessed (unless it is pre-compiled) so web.config is used. ...Show All
