• Visual C# Allocating memory throws exception when trieng to use native code dll

  Hi, I need to use a native code dll in my application. I am working on .NET2 env, written in c#. When I try to use the Init method in the native dll, it throws the following exception: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." I know this method supposed to open a com port and allocate a block of memory. I wrote a .NET wrapper for this dll. The h. file of this native dll includes 2 structures: 1. typedef struct ALARMREC { int Flag; int AlarmType; int AlarmUnitNum; int AlarmUnitWing; int AlarmLocation; int AlarmDelayFlag; char AlarmTime[20]; }alarmRec; 2. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Locking vertex and index buffer while rendering

  Let me see if I got this one right. I have a vague memory of reading that if I have a vertexbuffer and lock it with the discard flag, then I can get a buffer to write into while the gfx card is still rendering the previous buffer that I locked. Is this correct Will I need to do this in two threads then As far as I know, the drawPrimitives call is blocking so it does not return before rendering is done. What I would like to do is to render with a vertex buffer and an index buffer while I am showeling vertices into a vertex buffer and an index buffer that I locked. That way I can double my speed, assuming that the showleing and rendering takes the same amount of time. Thomas Greenleaf wrote: Will I ...Show All

• Visual Studio Team System Latency when Connecting via VPN remotely

  Hello! Are there any limits or recommendation for the latency to a remote place The connection is done with two VPN routers. We are currently setting up that connection and it seems, that we have a latency of about 250 - 300 ms. Will that be good enough Any practical experiences about latency Regards CSharpNewbie22 Team Foundation Server is optimized to work on connections with high latency and low bandwidth so you shouldn't face any issues. I've used exactly that kind of set up for intensive development / testing using TFS for the past year and had no problems. My latency is usually around the 200ms mark, but it can occasionally spike up to 2000 ms and I have never noticed any problems wha ...Show All

• .NET Development Boolean or bool?

  I noticed when I am declaring fields that their are both a Boolean type and a bool type private Boolean mIncreasedInvasion = false ; private bool mExecuteScript = false ; What's the differance between the two Is there a performance differance Should one be used instead of the other Or are they both the exact same thing Thanks for clearing this up for me, Scionwest No difference. From MSDN: The bool keyword is an alias of System.Boolean Most people use the bool keyword (and similarly for int, long, string etc). ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. No way to set the SpriteBatch transform ?

  I can't find a way to set the transform of the underlying ID3DXSprite of the XNA SpriteBatch. Am I missing something Thanks L. The SpriteBatch class doesn't support any transform state members. You will need to perform any transforms yourself before calling Draw methods. The overloaded Draw methods also contain options for scaling, translation and rotation transforms. ...Show All

• Audio and Video Development Playing sounds from markup

  How would one go about playing sounds in markup Specifically, I want to trigger audio from a focused state without passing an event to script. I understand that I can create a wav object, but how is the object sent to Player.audio.effect in markup Thanks! Do you mean that if you have very fast animations (eg, move 1000px over 2 frames) it looks bad Well.... not much you can do there I am afraid. There's only 24 (or 50/60) frames per second to draw in. Make your duration longer or your distance shorter, or you *could* create a version of you graphic that was deliberatly "blurred" and use that so it looks like a smoother animation. ...Show All

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

  XNA may be the greatest thing since sliced bread, but I don't see it getting a lot of support until you make a simple web page that explains what features the XNA framework supports and why I would want to use it. I'm not going to download the thing just to figure out what it is.
