  • How do I load a Direct X .x 3D model in iPhone SDK?

    - by Alex
    I have been searching the internet for the last few days trying to figure this out. My goal is to draw a textured and animated .x file exported from a 3D program. I found a tutorial of how to load and draw a .obj file, which I understand, but the tutorial doesn't say how to texture it, and .obj doesn't support animation. The .x file structure is human readable just like .obj, but I have no clue how to texture it, and I might be able to figure out how to animate it, but I would prefer to be instructed on that. Any help would be GREATLY appreciated.

  • Getting \ building latest NHibernate build

    - by Alex Yakunin
    I'd like to get the latest NHibernate build or build it by my own. The build available at SourceForge is dated by Nov 2009, although I see there was a lot of activity later, especially related to LINQ development. So what is the best option? I can: Get the latest source code and try to build it. Are there any instructions for this? Get one of latest builds shared by someone else. Are there any people maintaining such builds? Please note, that I'm not interested in 8-month old builds - I need the latest code for tests (LINQ, performance). I know there is a similar question, but it looks like top answers there are outdated.

  • I have data about deadlocks, but I can't understand why they occur (MS SQL/ASP.NET MVC)

    - by Alex
    I am receiving a lot of deadlocks in my big web application. http://stackoverflow.com/questions/2941233/how-to-automatically-re-run-deadlocked-transaction-asp-net-mvc-sql-server Here I wanted to re-run deadlocked transactions, but I was told to get rid of the deadlocks - it's much better, than trying to catch the deadlocks. So I spent the whole day with SQL profiler, setting the tracing keys etc. And this is what I got. There's a Users table. I have a very high usable page with the following query (it's not the only query, but it's the one that causes troubles) UPDATE Users SET views = views + 1 WHERE ID IN (SELECT AuthorID FROM Articles WHERE ArticleID = @ArticleID) And then there's the following query in ALL pages: User = DB.Users.SingleOrDefault(u => u.Password == password && u.Name == username); That's where I get User from cookies. Very often a deadlock occurs and this second LINQ TO SQL query is chosen as a victim, so it's not run, and users of my site see an error screen. I read a lot about deadlocks... And I don't understand why this is causing a deadlock. So obviously both of this queries run very often. At least once a second. Maybe even more often (300-400 users online). So they can be run at the same time very easily, but why does it cause a deadlock? Please help. Thank you

  • jquery Iframe src attribute

    - by alex
    Why does x alerts undefined for iframe but works for embed. I'm grabbing the iframe or embed code from a textarea <iframe src="http://www.youtube.com/embed/9kiWvkj2ldWiU?hd=1"></iframe> var textarea = $('#embedModal textarea'), textareaValue = textarea.val(), $embed = $($(textareaValue).find('iframe')), x = $embed.attr('src'); alert(x); //alerts undefined for iframe If you change find('iframe') to find('embed') and you try with the below embed code. then i'm able to get the value of src, but with iframe i get undefined. Seems strange. <embed src="http://www.youtube.com/embed/9kiWvkj2ldWiU?hd=1"></embed>

    How to make this method return boolean value, depending on query return. False - nothing, True - data exists.

  • Call to undefined function phpinclude_once()

    - by Alex Zylman
    I'm making a new php page and I get the error Fatal error: Call to undefined function phpinclude_once() in /home8/nuventio/public_html/marketing/pb2/dashboard.php on line 1 I'm not sure why I'm getting this error, I've done previous pages the same way as this with no problems. This is the line in question: <?php include_once("../utils.php"); ?> After that it just goes into regular HTML code. It works fine without that line.

  • Possible to push a hash value only if it is unique?

    - by Structure
    In the example code below, assuming that the value $keyvalue is constantly changing, I am attempting to use a single line (or something similarly contained) to test and see if the current $keyvalue already exists. If it does, then do nothing. If it does not, then push it. This line would reside within a while statement which is why it needs to be contained within a few lines. Preserving order does not matter as long as there are no duplicate values. my $key = "numbers"; my $keyvalue = 1; my %hash = ($key => '1'); push (@{$hash{$key}}, $keyvalue) unless exists $hash{$key}; I am not getting any errors with use strict; use warnings;, but at the same time this is not working. In the example above, I would expect that since the default value is 1 that the $keyvalue would not be pushed as it is also 1. Perhaps I have gotten myself all turned around... Are there adjustments to get this to work or any alternatives that can be used instead to accomplish the same thing?

  • How do I parse data received in a memorystream?

    - by Kerberos42
    I'm new to using sockets. I have a very basic client that sends a request, and waits for a response. The response is one stream, but has two parts. The first part is prefixed with ANS and is a set of key/value pairs in this form: KEY:Value with each pair on a separate line. The second part of the response is prefixed by RCT and this is pre-formatted text that needs to be send directly to a printer. So what would be the best way to extract both parts of the response, and in the first part, get each Key:Value pair. I might not even need them all, but I have to look at each one to see what the values are then decide what to do with it. I'm currently writing the response out to a textbox just to understand what its doing, but now I need to actually do something with the data. Here's a data sample, as it is received: ANS Result: Data Received RCPRES:Q[81] TML:123 OPP: MRR:000000999999 <several dozen more KEY:Value pairs> RCTNov 05 2013 04:03 pm Trans# 123456 <pre-formatted text>

  • Select <a> which is the second <a> on a page that contains some href text?

    - by Alex
    Hello there, I'm working with a page that has several links that contain the same href text, and I need to select the second anchor element on the page that contains said href text. Here's a simplified version of the link structure of the page: <a href="same/link/to/stuff/">same link</a> <a href="same/link/to/stuff/">same link</a> How do I fashion my selector so that it only selects the second anchor in the above example? Thanks!!

  • Contact page MVC workflow

    - by alex
    All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?

  • Catch a generic exception in Java?

    - by Alex Baranosky
    We use JUnit 3 at work and there is no ExpectedException annotation. I wanted to add a utility to our code to wrap this: try { someCode(); fail("some error message"); } catch (SomeSpecificExceptionType ex) { } So I tried this: public static class ExpectedExceptionUtility { public static <T extends Exception> void checkForExpectedException(String message, ExpectedExceptionBlock<T> block) { try { block.exceptionThrowingCode(); fail(message); } catch (T ex) { } } } However, Java cannot use generic exception types in a catch block, I think. How can I do something like this, working around the Java limitation? Is there a way to check that the ex variable is of type T?

  • Is RIA Services right for our Silverlight app at this point?

    - by Alex
    Hi, I'm looking at Silverlight architectures and RIA Services looks interesting, but I am a bit concerned about its prelease status and how the feature set will change. We need our client app to be as responsive as possible over a slow network link, so a high priority is a solid sync system for pushing model state changes from the client back to the server. Will RIA Services help us in this regard or will I have to roll my own logic to do this ? Are there any other frameworks that can assist with this? Is the feature set involved in these requirements liable to change much in the next couple of months? If it makes any difference, our frontend is 100% Silverlight, so we dont need to worry about exposing SOAP APIs from the server or anything like that. It appears to me that RIA so far is a bit more mature for Silverlight use. Is this correct?

  • OpenID login on local development server for google app engine

    - by Alex Jeffery
    Are you able to use open id to log into the local development server with google app engine sdk version 1.4.1 and python 2.5? When I execute this self.redirect(users.create_login_url(continue_url, None, openid_url)) I get redirected to http://localhost/_ah/login rather than the openid url. The openid url and continue url are valid. My app.yaml looks like this - url: /_ah/login_required script: do_openid_login.py - url: /users/(.*) script: routers/user_router.py login: required If I browse to http://localhost/users/ I am also redirected to http://localhost/_ah/login rather than http://localhost/_ah/login_required Is there a config issue or does openid not work locally?

  • Which DB Server should I use?

    - by Alex
    I have to develop a new (desktop) app for a small business. This business currently has an Access database with millions of records. The file size is about 1.5 GB. The boss told me that searching on this DB is very slow. The DB consists of a single table with about 20 fields. I also think the overall DB design isn't great. I thought to use another DB server with a new design to improve both performance and efficiency. Considering this is a relatively small business, I don't want to spend much for a DB license, so I want to ask you what would you do. Continue to use Access, maybe improving and optimizing the DB in some way Buy a DB server license (in this case, which one?) ? (any idea?)

  • Just how much do I want to make virtual?

    - by Alex
    I am writing an abstract superclass where literally every method is going to be overridden. There is some default functionality I could implement, but most of the time it's enough to leave the implementation to the subclass writer. Since just about every method is going to be overwritten, how much should I make virtual and how much should I just leave as regular methods? In the current incarnation, everything is virtual, but I still haven't let this loose to anyone to use, so the design is flexible. What advantages/disadvantages are there to virtual functions? Links to good reading material about this would be appreciated.
