• Game Technologies: DirectX, XNA, XACT, etc. XNA Basics

  I am currently teaching myself VB.net and I wanted to know if there was any other languages reccomended for those wishing to use XNA and if so, good reading to learn these languages. I am currently delving into Jesse Liberty's Learning Visual Basic.net. Thanks for any help In my opinion, when you're a developer, all languages are useful. For XNA, C# is definitely the MOST useful. But really, once you understand development, learning another language is just learning the syntax of that language, the logic of the language remains the same. And you're in luck for the C# recommendations, I just recently started a thread collecting links and suggestions for sites and books about learning C#. You can find it here . I hope that helps! ...Show All

• Visual Studio Team System How to change link of "Show ProjectPortal" in Team Explorer

  Hello everybody, I would like to point to a different location for a single TeamProject. In Team Explorer there is the menu item "Show ProjectPortal". How can I change the link target All other TeamProjects should keep their link targets... Kind regards, Rudi Hi Rudi, There currently isn't a way to change the portal for a single team project. TFS has the addresses of the one WSS server stored in a database table, and it uses that combined with the name of the team project to create the url to the portal. -Dennis ...Show All

• Visual Studio Team System Is there a way to view all file changes under a directory?

  I want to get the list of files changed under a directory hierarchy (not the changesets), I don't care about the other files changed outside of the directory hierarchy I want to look at (that would just be noise). Is there a way to get this information without digging into every changeset Thanks, Do you want to see file changed on the local drive, compared to server location, or between two changesets, or yet something else Either way our Powertoys/Powertools "tfpt treediff" is tool that should be useful for you ( http://blogs.msdn.com/bharry/archive/2006/09/07/744993.aspx ). ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Beta2 Math Problems

  I implemented a collision detection system with XNA Beta 1, which surprisingly doesn't work at all with Beta 2. Does somebody know, if there are changes in the structures Vector3 or Plane, or do I have to analyse the cause of this problem myself. I recognized the member Distance in the Plane-struct is now named D. Perhaps there are more changes in this structure Yes, I’ve confirmed that there is a bug in our code which uses un-normalized vector to compute D value. Thank you for your report and apologize for wasting your time. ...Show All

• Windows Forms events processing slows down painting

  I have a custom control which can be resized and every time it's resized it is obviously invalidated and its Region property changes. After Invalidate() is called the control also fires an event which outputs a function of the size of the control. This is the problem: the value contained in the event has to be shown in a label included in a TableLayoutPanel, if the event is processed, that is, it is displayed in the label, the redrawing of the control does not follow the resizing continuously. It is as if some OnPaint event was lost. The problem is present only when updating a label contained in the tablelayoutpanel. If I use a Label which is a child of the main form it all works correctly. I don't know if this is important but I did not o ...Show All

• SQL Server DTExec and Pasword Prompting

  A colleague of mine is having problems when trying to schedule package execution via a .bat file that executes a .dtsx on a sql server (not file system). The scheduling system that is employed by the company requires a .bat file to execute the package. The packages themselves move data from AS400 servers to SQL Servers. Occasionally (very randomly) when the scheduling system runs the statement in the bat files, the package prompts for password information (for connectivity). We've tried a number of solutions to this, mostly on the "ProtectionLevel" property of the package itself. We did some research and it seems as though there are a few options.What is the best solution to eliminate this from happening We certainly don't wa ...Show All

• SQL Server ERREUR to open a data base with SSMSEE

  I installed Visual Studio 2005 Standard Edition which contains SQL Server Express. I downloaded and installed SQL Server Management Studio Express. It run ! I established a connection server BellFixe\SQLEXPRESS (BellFixe is the name of my computer). Ok. The command " add " of the function " attach " of SSMSE allows to navigate on the disk and to attach diverse data bases but it refuses to open the directory D:\Documents and Settings\Alain (this path is the base of all my directories of data). This directory appears empty. I cannot thus attach the data bases which are under this directory ! I can open a data base only if it is elsewhere localised. Why this limitation of access and how to resolve this pro ...Show All

• .NET Development Is this normal or bad practice?

  Hi all, I have inherited a web service from a previous developer, and have noticed some strange in the way that they have implemented something in their web service. The webservice only has one method, GetData(). But in the header of the XML that gets sent to the web service there is an element called 'Operation', as follows... <XmlElement> <Header> <Operation>CalledMethod1</Operation> </Header> <Body> <Data>Data Used for CalledMethod01</Data> </Body> </XmlElement> ... now there are four methods on the server that can be called (or placed in the <Operation> elements). When run, the method is got, and then the relevant data that is passed in the <Data> el ...Show All

• Windows Forms Issue regarding the control redrawing...

  I have got two fields in a datatable consisting of "ID" and "FirstName", i have implemented two combobox to display those ID and "FirstName" separately....The requirement is that if i selected a certain "ID" then its corresponding "FirstName" should be reflected in the corresponding FirstName combobox. The vice-versa should also be true.Moreover those ID and FirstName should be in sorted order. So i used a binding source to sort the value in the combobox in "Enter" event. Such that when the control/focus enters "ID" the ID combobox is populated with the sorted IDs and when FirstName combobox is entered, the data are sorted my "FirstName". However i am gett ...Show All

• Visual Basic Can you digitaly sign your program?

  hey i was wondering can you digitaly sign your program and also make to be able to install into C:\Program Files is this possible thank you. You can digitally sign your application with a public/private key pair even in Visual Basic 2005 Express without purchasing a certificate. It may be neccessary to download the 2005 SDK (I hope not). There is a tool called sn (strong naming utility) that lets you generate a key file, you can use this tool to sign your assemblies and in your project properties under the "Signing" tab there is an option there (not the sign the click once manifest) to sign the assembly. That should provide some measure of security against tampering/spoofing, for you. ...Show All

• Visual Studio Express Editions Question Regarding StreamWriter

  When using a StreamWriter, is it possible to write to a specific location in a text file For example, if the file being written to contains several lines can I get a StreamWriter to begin writing at the end of line 2 If not, is there any other way to do this Thanks. StreamWriter outStream = File .AppendText( "f.txt" ); outStream.Write( output); Hi, You can use a StreamReader to help do it. For example, you want to write things after two lines in the file:             List< string > str = new List< string >();             using (StreamReader sr = new ...Show All
