• Game Technologies: DirectX, XNA, XACT, etc. Performance profiler and obfuscator

  I have two software questions. First of all does anyone know a good performance profiler package (besides CLR) Secondly, what is the best way to secure your intellectual property, by using an obfuscator or are there alternatives. What are the thoughts of Microsoft on this part. Cheers! Remmie wrote: ... does anyone know a good performance profiler package (besides CLR) ...

• Visual FoxPro a post card printer?

  ok i made a nice little software package for my first client and at one point in my prg he needs to print addresses on a postcard. .... the software works fine and does everything good. except every couple postcards that go through his standard (average) printer will jam and the printing will stop. Does anyone know the type of printer my client needs in order for him to print these things properly dimensions of post card 5 3/4 inch (length) 3 3/4 inch (width) thickness/height= your average laminated postcard.

• Visual C# How to convert an Object in session to OdbcConnection?

  How to convert an Object in session to OdbcConnection Thank you. the codes are here. OdbcCommand odbccmd2 = new OdbcCommand("select 查看 限 from 限信息 where 用 名='" + Session["UserName"] + "'", OdbcConnection(Session["dbcon"])); OdbcDataAdapter odbcadp2 = new OdbcDataAdapter(odbccmd2); DataSet ds2 = new DataSet(); In C# to cast an object to a type without doing any runtime checking (and hence throwing an exception if you are wrong) use the following syntax: ((OdbcConnection)Session["dbcon"]) To perform a safe cast that returns null if it is not correct then use this: OdbcConnection conn = Session["dbcon"] as OdbcConnection; N ...Show All

• Internet Explorer Development Problem debugging embedded Client Script using IE7

  We are getting an error when trying to debug client script (VBscript and JScript) from the Running Documents window using VS2003.  This only happens when the script is inline on an asp page.  If there is a .js file, there is no problem.

• Visual Studio 2008 (Pre-release) Strange menu bug with July CTP of Interactive Designer

  I just installed the July CTP of Interactive Designer on top of Vista build 5472. None of the menus across the top (i.e. File, Edit, View, Format, Project, etc...) will open up. I click on it and the background turns gray as if the menu is active, but none of the menu items display. Anyone else run into this problem Anyone have a fix Thanks! I am not seeing that problem on the same build of Windows Vista. The first time I tried, it appeared that there may be a problem...but it was just delayed the first time.

• Visual Studio Express Editions Respond (trap) Windows Pop-up messages

  I have been trying to find an easy (if possible) way to get status on a Windows pop-up window. For example I am using .CopyFile to copy say 30 files (individually) from on directory to another.

• SQL Server Return Top row from a ResultSet - SQL Server (TOP)

  Hi all, I need to return only the top row of a ResultSet that is generated from my Query but can't seem to find anything in SQL Server 3.0 Mobile that allows me to do that. I know in SQL Server (Desktop) I could use the TOP keyword. The query I have is as follows, and just need the top row. Now the returned resultset will, in time, be massive, and there is just no way I can afford to return this amount of data in my application only to take to the top/first row. The query I have is as follows...

• Game Technologies: DirectX, XNA, XACT, etc. Figuring out the angle a ship is pointing at

  Do any of you know Asteroids, that classic arcade game, something similar to that, I am trying to make (but much cooler of course ). I have just started with xna, and I wanted to do something like that, I would say that I am pretty proficient in C#, but don't know at all how I could figure out the angle of a ship, and change it when the person moves the keys...obviously, the x, y is easy, but how would you figure that out, and rotate the image through xna Is it easy Look in the XNA documentation under 2D Graphics -> Rotating a Sprite. It's childsplay. Either as a global variable (bad!) or as part of a player class (good!) you'll want to store a RotationAngle variable. Use this both in your Draw() method ...Show All
