• .NET Development NullReferenceException when enumerating on Synchronized Hashtable?

  Below is the code- Executing it generates a NullReferenceException on the "foreach" when trying to get the enumerator. I'm at a complete loss here- Running the "Enumerate" method on the Hashtable named "tmp" works fine. Anyone what's going on here is this a known bug, or am i not using Synchronized collections correctly Thanks =) -- Herk using System; using System.Collections; namespace TestSyncHashtableEnumerator { class Program { static void Main() { Hashtable tmp = MakeSampleHashtable(); Hashtable sync = Hashtable.Synchronized( tmp ); Enumerate( sync ); } static void Enumerate( object someCollection ) { ICollection collection = ( ...Show All

• SQL Server Merge replication foreign key problem

  Hi there. I'm somewhat new to merge replication, and I've been having an issue with one of the scenarios that I've been trying to get working. I am using SQL 2005 on the server, with 2005 express on the client. I have 2 tables: Photo - which has a PhotoID primary key PhotoData - which has a PhotoDataID primary key, and a PhotoID foreign key both primary keys are int, and set to identity. I only want the Photo table to replicate for the merge, because I want the data in the PhotoData table to only be called by demand through a web service (since the images in that table are too large to be included in the normal replication). However, when a client adds a photo to his local database (which adds a record in the photo table, ...Show All

• Visual Studio Team System Confusion with UrlToTest Attribute

  I'm a little confused about the UrlToTest attribute. According to the documentation the attribute "Specifies the URL that should be requested to give context to the test. This class cannot be inherited." but according to this post http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=226558&SiteID=1 running the unit tests always starts a new instance of the web app with a dynamically selected port. If so, it seems the test agent or whatever is doing the requesting of the url will not get a response. Unless of course one is lucky enough to guess the port. What I'm I missing about understanding the UrlToTest attribute Cheers, Aeden Hi Aeden, the     &n ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is XNA the tool for serious game developers.

  I'm trying to make the decision if our game development team should use XNA as the technology solution. The question is, if XNA is capabale, or is intended to be, a commercial game development tool set for serious game developers. Reviewing the majority of the posts here (XNA vs. C++/DirectX) It is a very powerful and fast development environment, however at the moment its range is limited to the Windows and Xbox 360, meaning that (at the moment ) you cannot develop as easily as you can with C++/DirectX for alternative next-gen platforms (Macintosh (hah, as if), Wii or PS3). I, however, haven't seen many remarks on the possibility to opening this to other platforms. ...Show All
