• Game Technologies: DirectX, XNA, XACT, etc. Calculate "slope"

  Okay, here's my problem. The game I'm making is a 2D platformer, where you use the keyboard to move the guy around. When you click somewhere on the screen, your shot is supposed to make a beeline for the coordinate you just clicked. Somehow, I need to calculate the projectile's "slope". Assume that (0,0) is the top-left coordinate of the screen, and (3,3) is the bottom-right. If my player is at (0,3), and I click at (1,1), then my shot should move at a rate of 1 unit horinzontally, and -2 units vertically, right That's easy to calculate, because you just subtract the player's coordinates from the click coordinates. If I click at ...Show All

• Visual Studio Team System Do Not Catch General Exception Types

  I have a question about the fxCop rule on "Do Not Catch General Exception Types"...I started some discussion on this in another thread but I didn't get a full answer to my question and I thought this topic was worth starting a new thread. I think I'm using the recommended Microsoft approach for Exception Management: I'm using the Enterprise Library Exception Management Application Block to handle exceptions At the "top of the food chain" I have defined some policies for handling exceptions and use the EM application block to determine how to handle, report, and log the error. In all cases at the moment, it simply ...Show All

• Visual Studio Team System Is it possible to create and execute my own SQL-queries against TFS-databases from within VSTS?

  I would like to create a Team Query that is more complex than the wizard inside Visual Studio is able to let me do (I would like to sum the remaining work and the completed work field and group it by users). I've managed to execute such a query against the database directly but I would like this query to be available to the public as a Team Query. Is this posible Regards, Kristofer You can create a report based on your query and deploy it to the team project's Reporting Services folder. The report will show up in the Team Explorer under the Reports folder. ...Show All

• Visual Studio Team System Exceptions in unit tests in secondary threads kills vstesthost

  Hi, I was told at the PDC to log this issue here. I have some asynchronous APIs like BeginWork(). I am writing some unit tests for these APIs. These APIs create threads to do the work and fire events to signify that work is complete. If there are uncaught exceptions in these secondary threads, VsTestHost dies without performing any further unit tests in the list which have not been executed yet. I wanted to know if this is a bug. If it is not, is there a workaround Thanks Pawan Pawan, Yes, as a workaround you can enable legacy unhandled exception exception handling by doing the following in vstesthost.exe.co ...Show All

• SQL Server how to create Extended procdure to invoke a webservice with C#

  Hi,    Can anyone help me in creating an Extended procdure that can invoke a webservice with C#. So, I don't know if you want to create an extended proc in C# calling a web-service or if you want to create an extebded proc calling a C# web service. Anyway, if the former - you can't. Extended stored procs can only be created using C/C++. If the latter, then Books On Line have some documentation of how to do it. However, if you use SQL 2005 you should not have to use extended stored procedures, you can write your code using C# (or any .NET language) and create the code as "normal" stored pr ...Show All
