• Game Technologies: DirectX, XNA, XACT, etc. StreamWriter text file - load Vector 2 and enums

  I'm making my own tile map game. It's similar to the tile tutorial from Jaegers, but class based (each Map has Screens and each Screen has Tiles which, in turn, have properties). Saving to an XML file is just too big (3 megs+ for a 5x5 screen map), so I'm changing over to saving a text file, but having problems loading the Vector2 and an enum TileList {grass, desert, water}. The save code works fine, but I can't figure out how to convert the stream when its loaded. Is it even possible to do this Or is there a better way to save data besides XML public static Map LoadTextMap( string fileName) { StreamReader reader; reader = File .OpenText(fileName); Map tempMap = new Map (); tempMap.Version = Convert .ToI ...Show All

• Visual C# toolStrip with Database connection

Then... SqlDataAdapter theDataAdapter = new SqlDataAdapter(theSQLCommand); DataSet theDataSet = new DataSet(); theSQLCommand.Connection.Open() theDataAdapter.Fill(theDataSet); //fills the results given back from SQL into the dataset theSQLCommand.Connection.Close(); this.theComboBox.DataSource = theDataSet.Tables[0].DefaultView; this.theComboBox.DisplayMember = ColumnName ...Show All

• Visual Studio 2008 (Pre-release) Sept Orcas CTP missing pieces

  I have installed the virtual base and Sept Orcas CTP. It seems to be missing some of the items I would have expected, even items listed in the readme. Specifically it is missing: 1. Extension methods. 2. Linq support for native C#. aka using the 'from' keyword gives a message "not implemented yet". I can call the templates directly but that would have worked in .Net 2.0 3. Object Collection initializers : aka. var mylist = new List<int> { 1, 2 }; 4. Anonymous Types. Though I did not see that this was included yet. Do I need to install other earlier CTP's to gain support for Linq for object collections. I would have thought extension methods would have been added. Is there a matrix anywhere that shows what is and what is n ...Show All

• Visual Studio 2008 (Pre-release) Tools for WCF

  First off, let me say, WCF is a dream come true. Its everything I've been wanting to develop distributed apps. Now that wcf is live: http://wcf.netfx3.com/blogs/news_and_announcements/archive/2006/11/08/We_2700_re-done.-WCF-is-live.-.aspx#comments I'm wondering how I should develop applications to take advantage of this new framework In general, I do not think its a good idea to run code developed using beta/ctp's in a production environment (licensing/support etc.). There are a few exceptions to this, but in general, I like to sleep at night, knowing that I'm running code developed using supported tools in the event that something does go awry. And to be honest, I cannot make the pitch to my boss saying we should run beta/ctp ...Show All

• Visual Studio Team System code coverage on a Web service component

  Is it possible to perform code coverage on a Web service component. The Scenario is: 1. There exists a Web Service component. 2. Client app refers the Web Service component via Web Reference. 3. When the client app runs I need to know what portion of the code was excuted in the web service component- not the proxy. You might want to try the Visual Studio Team System - Developers Forum for this question since the feature is part of that sku there may be more people actively using it there.

• Software Development for Windows Vista Transactions - ensuring consistency between WF and MSMQ

  Apologies in advance this might be quite a complex one! I should say at the outset that I don't want someone to write my solution for me, just am trying to understand a bit more about how to achieve transactionality in WF. I'm currently trying to pilot an STP engine using Workflow Foundation to prove its suitability. Everything in the engine is driven using transactional MSMQ queues. It's essential that no information is lost, and that the workflows remain in a consistent state with the contents of the queue. These are the scenarios I'm trying to tackle at the moment: 1. A message arrives on a queue and triggers the creation of a new workflow. 2. A message arrives on a queue and is passed into a waiting workflow. 3. A workflow ...Show All

• .NET Development Object.ReferenceEquals Implementation

  Can anyone tell me where I can check for the Object.ReferenceEquals Implementation I'm tring to figure out the differences between Object.ReferenceEquals, Object.Equals and ==. I've gone to the link below http://msdn2.microsoft.com/en-us/library/system.object.referenceequals.aspx It tells me what Object.ReferenceEquals about, but it does not tell me how it's implemented. Thanks. From MSDN, I know that there are a couple of methods in the object class like ToString(), Equals(),ReferenceEquals and so on. I want to know the codes inside these method. Is there a way we can do this Notes: I've checked the Object class in Mono project. Under the System.Object.Equals Method ( http://www.go-mono.com/docs/ ) An implement ...Show All

• Silverlight (formerly WPF/E) Differences between WPF/E and Flash

  Hi, I searched a lot on topic "Flash Vs WPF/E" but I could hardly get any concrete information. Can anyone suggest any useful information, URLs on "Comparative study between Flash and WPF/E". Regards, Santosh Kalkeri I doubt very much that the first release of WPF/e will have anything like as much functionality as Flash - unless it's not going to ship for about 5 years - which is quite possible knowing Microsofts track record :) In it's present form WPF/e is so far removed from Flash in terms of functionality that you can barely do anything useful with it at all other than create yet another media player. ...Show All
