• Audio and Video Development s

  Hi. I'm sending "dummy sample" when there are no data to send from source. butRequestSample() come buck so quickly and keeps spining until data are ready. It's really waste of CPU power. What should I do to stop this I'm trying to build something like a LiveTV player. Thanks. Kasumi. I'm guessing that you have an MFT downstream of the Media Source that interprets these dummy samples as "no data". If you give this "no data" sample a duration, then your MFT can just produce that duration's worth of silence (audio) or repeated frames (video) and return MF_E_TRANSFORM_NEED_MORE_INPUT from ProcessOutput only when those have been exhausted. This will keep MF f ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to disable driver anti-aliasing

  I need to preserve the exact colors (and thus, hard edges) when I read back the rendered image via an offscreen surface filled with GetRenderTargetData. There is an option in the control panel where the driver forces anti-aliasing for all applications. If I do not set the quality-performance slider correctly, I will get anti-aliasing. Is there a way (in code) to prevent that From my understanding, control panel settings is directly tuning driver's behaviour. Thus it is not possible for the application to decide or force something that will be overriden anyway by the driver. ...Show All

• Architecture Data Modelling Tool in Visual Studio 2005

  Is there any data modelling tool / feature available in Visual Studio 2005 Hi amit lohia I have just started working with Visio for Enterprise Architect and find that the ORM (object role modeling) is an excellent way to model your data models. I have been working with design of databases for quite some time and find this to be the most precise and - once grasped - most easy way of defining your data models. ORM models can with a few steps be converted into ER diagrams that are normalized beyond the 3rd normal form. Here is a good place to start: http://www.orm.net/ Good luck - dampbarn ...Show All

• Windows Live Developer Forums Firefox Polylines

  I'm trying to add a polyline for tracking of the previous location of mutiple objects. This works fine in IE(Of course) but on Firefox 1.5.0.4 on Mac and Windows all the lines are being put in one place instead of actually having the correct locations. The code is at http://www.wormley.com/t1.html The pushpins were added to illustrate the locations where each line should be(you have to zoom in, the tracks aren't very long) but both polylines are ending up near the left side in firefox. It still doesn't work without the pushpins. Thanks, -Steve Yep...I'm in the frustrating position of not being able to say anything definite. I can't tell you anything more than: "we know all about this" and "soon". Get it ...Show All

• SQL Server clean up data - when process runs next time

What is the best way to delete / clean up data when you re run the process Cheers, T ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA's use of Collections

  XNA uses Collections for a lot of things: ModelMeshCollection, ModelEffectCollection, EffectPassCollection, ModelMeshPartCollection, etc. which results in a lot of foreach iteration in code. I recently discovered the CLR Profiler and started poking around. It appears that using foreach on these Collections results in creation of SZArrayHelper and Enumerator helper objects. Most other systems are doing pretty well to avoid any constant object "leakage", and I'd rather keep it that way if possible (I come from the "No Dynamic Allocations at Runtime" school of console development). I'm still pretty new to C#, so what I'm wondering is if there are there ways to avoid this constant pressure on the GC -beyond hand unrolling t ...Show All

• Internet Explorer Development Sessions in IE7

  Hi I am pulling my hair out over this problem, and am getting to the stage where I'm gonna scream. All these pages work perfectly on IE6, Firefox, Netscape etc, but I have come across a problem when testing them on IE7. Here's the problem: I have a web based system where a user logs into the site. Upon signing in, a number of PHP $_SESSION variables get populated with data, so that the subsequent pages know that he is allowed to visit them, and who he is. One of these variables is: $_SESSION['username'] At the top of all subsequent pages, the php script reads: < php session_start(); if (!isset($_SESSION['username'])) { header("Location:unauthorised.php"); exit; } > This effectively checks to see if the user is lo ...Show All

• Visual Studio Values of different documentation modules for a new learner

  - What s the difference between Tutorial, Walkthrough and quick start and what re the differences of their added values to a new .Net learner. I mean when should I use each of those. Also when should use Index in documentation and when should I use the search (Ctrl Alt F3 in the VS2003 documentaion) Thank you I see a quick start as a set of "try this" steps to help you get started in understanding a feature or technology. I see a walkthrough as a set of "try this" steps to help you accomplish a specific task or create a specific type of project. I see a tutorial as a walkthrough with additional commentary and discussion. I would say use the index when you want to look for content by a particular keyw ...Show All
