• Game Technologies: DirectX, XNA, XACT, etc. RectangleF?

  I've seen a thread here regarding the fact that XNA framework is currently missing the RectangleF class. Can I confirm that you are or aren't adding this class to the framework It's really almost essential for my game - I can't use the normal Rectangle class for the bounds of sprites/GUI controls because often I need to increase the location and/or position by values such as 0.25F. Anyway a quick yes/no/still unsure would be great please. Can't speak for the XNA guys, but I hope they don't add RectangleF. It would be sufficient if they added some overloads to SpriteBatch.Draw that take Vector2 values or float scalars. Even if they don't do either of the above, its VERY easy to write your own SpriteBatch equ ...Show All

• Visual Studio Team System msmdsrv using 50% cpu for minutes

  When running reports with cumulative account response time because extremely slow. Msmdsrv on the server starts using 50% cpu for minutes. You are right, my version of the query works in SQL Management Studio but I didn't test it in the report designer tool.  You are seeing the error because the [Date].[Week] dimension attribute is a hidden attribute.  [Date].[Year Week Date] is the right one to use. The key is " [Date].[Year Week Date]. CurrentMember . Member_Key " would give you what you need, which is the date for the week.  You can use this expression to create a calculated member in the Query Designer so you don't have to write the whole query out in MDX.

• Game Technologies: DirectX, XNA, XACT, etc. Quake XNA update

  Since the XNA 1.0 release I have been quite busy at first trying to run stuff on my XBOX360 and then doing the jump to a fully working port of Quake (best deathmatch ever!) So after 3 week of hard part time work on this I can now see something that look not too bad =) The lightmaps still have issues but I'm quite happy of the result so far. Before starting I had a good knowledge of C# but I my C/C++ skill are still far behind but enough to understand what the Quake code was about in most case. This is my first 3d engine ever but in RL I'm an animation TD for a major game publisher, meaning that I do understand quite well what I had to do and how to do it. So far I'm having a really good time using this and I don't have much to complain abo ...Show All

• Visual C# Debugger access error

  I am working on a machine running MS Visual Studio 2003.

• Visual Studio Express Editions How to output above ascii character set?

  Hi, I am trying to ouput commands that are above the ascii character set. What I am doing is this: com2.writeout("128WAKE") But what I need is the decimal equivalent of 128 and not the ASCII representation of 128. I need to do the equivalent of Printf("%d128"); if that is possible. Thanks!! I think you need the binary equivalent. I assume you want these in bytes Esentially what you are saying is that you want a string of bytes with but 7 set as I understand you. ...Show All

• Smart Device Development GetKeyState Method

• Visual C++ Passing Unmanaged Class by reference to Managed Class Constructor

  I have a MainForm. It has two child forms. The program reads in large SEGY files (2gb -> 100gb), appropiate data and read settings are stored through the class system that has a main controller "SEGY.H" & "SEGY.CPP". They a coded in pure C++. My two child forms are managed. I want to pass a reference for SEGY from the MainForm to each child form when they are required to be shown to the user, obviously to avoid copying large amounts of memory.   I cannot pass a native class by reference to a managed class through the managed classes constructor.  I have tried (code in mainform): private: SEGY *Segy;        //it then gets constructor call when filename is chose CHILDFO ...Show All

• Windows Live Developer Forums Programatically display PushPin's Details Balloon?

  I've got a pretty basic map that loads a public collection from local.live.com, adds the layer to the map, and also outputs the entries as a list (as text) where each item on the list is a link such that when it it clicked, the map is centered on that point/pushpin. I'm doing this with a LayerLoaded() call back when the layer is loaded which pases the collection of points. We loop through the points and output an A tag with an appropriate javascript attribute and then write all of this out to a DIV placeholder. I'm looking to add a few additional features: 1. I'd like the pushpins to be numbered, corresponding with the numbers on the list (which are just generated in the order they are written out). 2. More importantly, I'd lik ...Show All
