• Visual Basic using an interface

  I am trying to use an interface but getting a null reference exception. The code is below. The reference to interface Ireg returns a null reference exception in the line "cookie = Ireg.RegisterPlugin(GUID, True)". Please don't pay attention to the program itself. This is just meant to be a sample of declaring an interface. If I declare Ireg using "new", it says "Interfaces cannot be declared as New".... so I tried declaring Ireg with "new" I get the null reference.

• Visual Studio Team System dropped user

  I deployed my project to the target and after deployment it dropped my user. Understandable, I could no longer connect to that database. How do I prevent that I looked in the post deplyment scripts and found nothing specific to my user. I do not have a server level role. Only dbo_owner for the target database. Paul It probably dropped your user because it didn't exist in the source (project ) but did exist in the target (deployment database). Amos. ...Show All

• .NET Development FtpWebRequest - Access to IBM AS/400 FTP Server - 501 Character (/) not allowed in object name.

  Hello everybody I'm trying to communicate with an AS/400 FTP Server. As a first try I just execute the WebRequestMethods.Ftp.ListDirectory method, which translates to the NLST FTP command.

• Game Technologies: DirectX, XNA, XACT, etc. C vs C#

  Currently I'm taking a C class at my university and I was wondering how different is C# from C code wise. Thanks Sebastian You make me so happy, it doesn't seem like I am the oldest one here. But I can concur with latest speaker here. I also found the transition pretty natural from C and assembler to C++ and then java/C#. I agree that you might be a bit sloppy with java / C# since you have the garbage collector but otherwise they are superior in handling your difficulties. I also found the concept of DirectX/3D math much harder to pick up than the programming. But now it works pretty decent :) Good luck ...Show All

• Visual Studio 2008 (Pre-release) WCF Performance hit when connecting through proxy server

  I have been struggling with Performance of my WCF Web Service. The problem is whenever we make our Web Service call go through a proxy server in place of direct connection to the server, it takes a lot of time to connect and complete call. Since Server and Client machines are both on same network, we have made the call go through proxy by having the 'Bypass Proxy server for Local addresses' check box unchecked in Internet Explorer on Client machine so that connection is made through Proxy server. In this case the connection is really slow. If we have 'Bypass Proxy server for Local addresses' check box checked than Client makes the direct connection to server which is really fast (15ms compared to 359ms for the same call). I am getting ...Show All

• Silverlight (formerly WPF/E) How well does WPF/E and WCF play together?

  How much thought have been given to WCF as part of the development plans of WPF/E As far as I can see, you are currently limited to what you can accomplish with standard JavaScript objects, which limits you to XmlHttpRequests. I see some real benefits if I were able to do any type of socket connection, and not be limited to HTTP's push/poll model. With WCF on IIS7, i would be able to do non-HTTP requests on port 80, (port 80 is important to avoid any firewall issues), but as far as I know, I don't have any way of leveraging this from the client-side. Are there any plans to include a new socket object in WPF/E that we can use from JavaScript Flash already have this capability, although it unfortunately only works on ports above ...Show All

• SQL Server Generating Scripts for Table Alterations in SQLServer

  Hi, I am using SQLServer and I would like to track changes or generate scripts for every change or alteration made to the table.. Please help me with any ideas..

• Visual Studio 2008 (Pre-release) Adding Web Reference in VS 2005 to WCF Service

  Hello, As I’ve found out yesterday, it’s important to create a proxy class for ‘WCF web service’ using svcutil.exe even though it uses 'basicHttpBinding'. If one does it through VS2005's 'add web service' routine, the created proxy allows passing string fields only. All value types doesn't go through. I mean the proxy class looks correct with all fields having correct types. But when I attach the debugger to the WS I see default values only for types like int, short, DateTime etc. Am I doing something wrong nefis Please see my blog post at http://blogs.msdn.com/eugeneos/archive/2007/02/05/solving-the-disappearing-data-issue-when-using-add-web-reference-or-wsdl-exe-with-wcf-services.as ...Show All

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

  I personally put up a XNA chatroom to build a community that is already here and to better get to know each other. If you want to quickly inform somebody or get some information or help with something go there. The only problem for me right now is getting idlers in the channel. I know forums are a great way to help people, but sometimes just talking to each other about things like this is even better. Come and idle and help build a community even bigger and also build a place to help each other out. Its XNA Development, its for us. (That would be a sexy slogan).
