• Visual Studio Team System Can a test belong to multiple Test Lists?

  Our project is getting to the point where there are so many tests, that we would like to organize them into groups. I attempted to use Test Lists to do this, and set up different batches of tests that would be run for different purposes. I would like a list for all unit tests, a list for unit tests relating to a specific functional area, a list for all integration tests, a list for all unit tests + all integration tests, etc. However, it appears to me that a test can only appear on one test list. Is this true If not how can I add a test to multiple lists Right now I am just selecting the All Loaded Tests in Test Manager, and dragging the test name to the target Test List on the left. Thanks, Dylan ...Show All

• Visual C++ Calling C# Main() in C++.NET

  Hi, I am a newbie and I wanted to know if it is possible to call an application written in C# using C++.NET. I know that Main() is the entry point of the this C# application...so can I launch the C# application by calling its Main() from a C++.net program Is this related to managed and unmanaged code Do I need to include the class where Main() is located in the C++.net program Should I do that by "#using classWhereMainIsWritten" or using the namespace Help! If you simply want to launch the C# application from your C++/CLI application (which would result in the C# application’s Main entry point function being called) then you can simply launch a new process to handle it.

• Game Technologies: DirectX, XNA, XACT, etc. Not Using Vector2 in my 2D Game Engine

  I just recently changed, oh, about a 1000 lines of code in my game engine. Instead of using Vector2 for things like position and size, I decided to use floats instead. Does anyone else use Vector2's as their main position and size data types in their 2D game Right now, I have the code for both versions, and I'm trying to make entirely sure floats are the way to go before throwing one of them away. Any comments Since Vector2 is just a pair of floats it will use up the same space as two separate float variables. This is no different in .NET than in C++. So, I cannot see why it would be less efficient to use the struct vs float vars. ...Show All

• SQL Server ODBC connection to SQL 2005 Express

  I am attempting to setup a SQL Server 2005 Express database as a backend to an Access MDB, and need to establish an ODBC data source for the backend database. On two different systems (Windows XP Pro and Windows 2003 SBS), I get an error that says I cannot connect to the SQL Server.

• Visual C# C# 2.0 closures - bug or feature?

  Would anyone care to explain me what is happening there To me, both i and ii seem to be local variables within the same scope, so why the compiler treats them differently using System; using System.Collections.Generic; internal delegate void VoidDelegate(); internal class Program { private static void Main() { List< int > a = new List< int >(); for ( int i = 0; i < 10; i++) { a.Add(i); } List<VoidDelegate> handlers = new List<VoidDelegate>(); foreach ( int i in a) { handlers.Add( delegate { Console.Write(i); }); //If we comment out line above and uncomment two lines below, we'll get the expected "0123456789" result. //int ii = i; //handlers.Add(delegate { Console.Write(ii); } ...Show All

• SQL Server Complex SQL Query - Joins, Max, Union

  How to find maximum value from two tables have the same field name For example: Table -1 has field calcuated_price and its max value is 3500 and then Table -2 has same field name calcuated_price has max value is 3000. Nishith Well, there are three things to discuss here. First off this statement: Table -1 has field calcuated_price ... then Table -2 has same field name calcuated_price This just shouts out "design issue" Of course it is totally out of context, so these may be quite different things you have modeled and you just want to compare their prices. The point I am trying to make is: if the tables have the same things in them, or even common columns that have the same meaning, then you ought to consider making ...Show All

  Hi, I'm a newbie in C# and SQL Server and I'm trying to add a SQL Database within Visual C# 2005 Express Edition .

• Visual Studio Express Editions Project Folders not getting created during debug?

  I thought I read something about this somewhere but I can't find it. I've created some sub-directories for one of my VBE applications. Whenever I debug(F8) the app, it never creates these folders and I either have to create the folders and their contents by hand or put up with the multiple exception errors. Is there an option for the project to automatically create all files/folders that have been added during program design Thanks Ted There is no code. Solution Explorer, right click, new folder. The folders I create in solution explorer aren't getting created during debug. They do if I publish, but never in debug. Ted ...Show All

• Software Development for Windows Vista Can DataExchange service hold variables?

  I would like to know whether "LocalCommunicationServices" could have a .NET property to hold data returned from within the workflow .This way the host can get hold of this property and tap the data out instead of using events where the same activity would raise a custom event and the host would recieve the data through the events arguements.(This is a long way of getting things done.....). The doubt is whether the information on this property is volatile especially when whe have our runtime hosted in a webservice and caters to many client calls. Thanks in advance.... You can only place the ExternalDataExchange attribute on an interface. If the host wants to know a value of an act ...Show All
