  • Anyone Experiencing Slow Builds With VS2010?

    - by MrKWatkins
    Hi, We've recently upgraded to the final release of VS2010 and are experiencing very slow build times compared to the same code under 2008. I was wondering if anyone else is experiencing the same so I can work out whether it's just our environment or not? A few details: Using VS2010 Ultimate on Windows 7 with fairly beefy machines, talking to TFS 2010. The solution has been upgraded from VS2008 but still builds against .NET 3.5 and ASP.NET MVC 1.0. It doesn't seem to be the compilation itself taking long but something else in the build process. This is because even projects that are up to date and don't need compiling are taking a few seconds or so to process. It's not due to an Visual Studio addin because a couple guys in the team haven't installed any. The first build after loading VS2010 is pretty quick, then they seem to slow down over time. For example on of the projects in my solution just took 00:00:00.08 to process after a restart. (The project was up to date and didn't need compiling) I then immediately hit rebuild and it jumps to 00:00:01.33. We're also experiencing the problem with another solution that uses .NET 4.0 that was building perfectly fine under VS2010 RC. There are no build events or anything like that I can blame, just straightforward assembly builds. The IDE is not very responsive during the slow builds. Anyone else has similar problems? Update: It looks like the resolving assembly references is taking a long time. Looking at the MSBuild diagnostic output or the example above the first build has 30ms for ResolveAssemblyReferences, the second build has 800ms. Subsequent builds seem to be taking longer copying stuff around, e.g. CopyFilesToOutputDirectory jumps from 1ms to 27ms.

  • Is there a Visual Studio (or freeware) equivalent for Expression Blend's "Edit Template" feature?

    - by DanM
    In Expression Blend, you can view and edit the control template of objects in the "Objects and Timeline" panel. I'm wondering if there's an equivalent feature in Visual Studio or if there's something free (or very inexpensive) I can download that will allow me to do this. Here's a screen cap from Expression Blend that shows what I'm talking about: Doing this for DataGrid results in the following: <Style x:Key="DataGridStyle1" TargetType="{x:Type Custom:DataGrid}"> ... <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Custom:DataGrid}"> ... </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsGrouping" Value="True"> <Setter Property="ScrollViewer.CanContentScroll" Value="False"/> </Trigger> </Style.Triggers> </Style> (The ... is of course replaced with setters and the contents of the control template.) This is a very useful starting point if you want to create a custom style and template for a control. It seems like you can do pretty much anything you can do in Blend in Studio, but this one is eluding me. Any ideas? Edit I'm also curious if this feature will be in Visual Studio 2010. Anyone know?

  • Read header data from files on remote server

    - by rejeep
    Hi! I'm working on a project right now where I need to read header data from files on remote servers. I'm talking about many and large files so I cant read whole files, but just the header data I need. The only solution I have is to mount the remote server with fuse and then read the header from the files as if they where on my local computer. I've tried it and it works. But it has some drawbacks. Specially with FTP: Really slow (FTP is compared to SSH with curlftpfs). From same server, with SSH 90 files was read in 18 seconds. And with FTP 10 files in 39 seconds. Not dependable. Sometimes the mountpoint will not be unmounted. If the server is active and a passive mounting is done. That mountpoint and the parent folder gets locked in about 3 minutes. Does timeout, even when there's data transfer going (guess this is the FTP-protocol and not curlftpfs). Fuse is a solution, but I don't like it very much because I don't feel that I can trust it. So my question is basically if there's any other solutions to the problem. Language is preferably Ruby, but any other will work if Ruby does not support the solution. Thanks!

  • Echo a multidimensional array in PHP

    - by Jennifer
    I have a multidimensional array and I'm trying to find out how to simply "echo" the elements of the array. The depth of the array is not known, so it could be deeply nested. In the case of the array below, the right order to echo would be: This is a parent comment This is a child comment This is the 2nd child comment This is another parent comment This is the array I was talking about: Array ( [0] => Array ( [comment_id] => 1 [comment_content] => This is a parent comment [child] => Array ( [0] => Array ( [comment_id] => 3 [comment_content] => This is a child comment [child] => Array ( [0] => Array ( [comment_id] => 4 [comment_content] => This is the 2nd child comment [child] => Array ( ) ) ) ) ) ) [1] => Array ( [comment_id] => 2 [comment_content] => This is another parent comment [child] => Array ( ) ) )

  • Is it a wise decision to go from dev to third line/Tier 3 dev support?

    - by dotnetdev
    Hi, I am an experienced, mid-level developer. However, I recently spotted a job for a company which is small but has a lot of emphasis on training(beyond the basic technical training, but also mentoring, leadership training, etc). The role is 3rd line so still very technical. It's in app support so it's post implementation development rather than pure out-and-out development like I do now (or don't, as the senior devs do all of the interesting work). However, and this is the question - is this sort of career move common? Also, wouldn't a tech support role be a big shock to the system because I've never dealt with customers? I therefore think it's a bad move? Working in dev, I am used to the lack of customer contact and it is all filtered through by my manager. But in tech support, contacting customers/rude customers could be scary. I don't mind fixing other people's mistakes (better than me making mistakes!) and doing post-implementation dev for production systems (will give me a lot of discipline), and I do get bored sitting in the same place looking/talking to the same people in suits (I work in a corporate environment). The company puts A LOT of emphasis on training and prospects, which I don't get in the current (big) company I work at. Any advice on how to handle tech support is appreciated! Thanks

  • $(window).load(function(){}); problem in Opera

    - by Slammer
    Hello. I need to recalculate body's main div height, than wait while all content (images) loads and only than show it to site visitor. To achieve this i used jQuery and CSS //CSS looks like body {display: none;} /* div block height calculator */ function recalculateHeight(id, add){ var height = $(id).height(); if (height < 650) height = 650; if (add) height = height + add; $('#left_div').height(height); $('#center_div').height(height); $('#right_div').height(height); } //recalculate height when page is fully loaded $(document).ready(function(){ $(window).load(function(){ $('body').show(); recalculateHeight("#center_div"); }); }); Everything works fine in IE, Firefox, Safari. In Chrome height calculation works, but seems that body doesn't hides, because all images loads as usual they should. In Opera, both functions doesn't work. Not page is showed when all content is loaded, not page calculation works. You would better understand what I am talking about: Site where this problem is Thanks for Your response, brgds

  • How important is it that models be consistent across project components?

    - by RonLugge
    I have a project with two components, a server-side component and a client-side component. For various reasons, the client-side device doesn't carry a fully copy of the database around. How important is it that my models have a 1:1 correlation between the two sides? And, to extend the question to my bigger concern, are there any time-bombs I'm going to run into down the line if they don't? I'm not talking about having different information on each side, but rather the way the information is encapsulated will vary. (Obviously, storage mechanisms will also vary) The server side will store each user, each review, each 'item' with seperate tables, and create links between them to gather data as necessary. The client side shouldn't have a complete user database, however, so rather than link against the user for gathering things like 'name', I'd store that on the review. In other words... --- Server Side --- Item: +id //Store stuff about the item User: +id +Name -Password Review: +id +itemId +rating +text +userId --- Device Side --- Item: +id +AverageRating Review: +id +rating +text +userId +name User: +id +Name //Stuff The basic idea is that certain 'critical' information gets moved one level 'up'. A user gets the list of 'items' relevant to their query, with certain review-orientation moved up (i. e. average rating). If they want more info, they query the detail view for the item, and the actual reviews get queried and added to the dataset (and displayed). If they query the actual review, the review gets queried and they pick up some additional user info along the way (maybe; I'm not sure if the user would have any use for any of the additional user information). My basic concern is that I don't wan't to glut the user's bandwidth or local storage with a huge variety of information that they just don't need, even if proper database normalizations suggests that information REALLY should be stored at a 'lower' level. I've phrased this as a fairly low-level conceptual issue because that's the level I'm trying to think / worry over, but if it matters I'm creating a PHP / MySQL server that provides data for a iOS / CoreData client.

  • What happens to exinsting workspaces after upgrading to TFS 2010

    - by user351671
    Hi, I was looking for some insight about what happens to existing workspaces and files that are already checked-out on people, after an upgrade to TFS2010. Surprisingly enough I can not find any satisfactory information on this. (I am talking about upgrading on new hardware by the way. Fresh TFS instance, upgraded databases) I've checked TFS Installation guide, I searched through the web, all I could find is upgrade scenarios for the server side. Nobody even mentions what happens to source control clients. I've created a virtual machine to test the upgrade process, The upgrade was successful and all my files and workspaces exist in the new server too. The problem is: The new TFS installation has a new instanceID. When I redirected on the clients to the new server, the client seemed unable to match files and file states in the workspace with the ones on the new server. This makes me wonder if it will be possible to keep working after the production upgrade. As I mentioned above I can not find anything on this, it would be great if anyone could point me to some paper or blog post about this. Thanks in advance...

  • First-time software contractor, building a system for a multi-site client; who should own the intell

    - by matthew
    I'm very new to software contracting; this is my first project. I've just built a point-of-sale software system for a client, and neither of us put a lot of work into the contract. I wrote that the software was "jointly owned" with exclusive license for use given to the client. The client is using it at one store and is very pleased with it. The client is also planning to expand to numerous stores over time, and wants to use it in every store. The client also now wants full ownership of the software, with me as the exclusive developer. I am very hesitant to allow this, and I am seeking previous experience. Should I sell the IP but demand royalties for every site at which it's installed? Should I demand royalties for every sale made using the software? Should I really start talking to a lawyer? A couple of other details: in terms of risk, it is fair to say that the client is assuming the risk, but the client is now using the software and exclaiming how great it is (and so I assume, how it is improving business). Also, the software is tailored to the client specifically, but could, with a bit of work, be repackaged and resold to other clients. Even if the client owned the IP I would certainly want to make sure that I then did have (significant) royalties on such sales.

  • Writing JavaScript from a Custom Control

    - by coffeeaddict
    I'm new to writing custom controls. I have MyCustomControl.cs and in my Render method I want to render out about 50 lines of JavaScript. What's the best way to do this, use the writer? protected override void Render(HtmlTextWriter writer) { writer.write(@"<script type....rest of opening tag here"); writer.Write(@" function decode(s) { return s.replace(/&amp;/g, ""&"") .replace(/&quot;/g, '""') .replace(/&#039;/g, ""'"") .replace(/&lt;/g, ""<"") .replace(/&gt;/g, "">""); };" ); I plan on having around 6 more writer.Write to write out some more sections here. Is that the best approach to actually perform the writing of JavaScript in this manor? or should I use ClientScript.RegisterClientScriptBlock? So what's the best practice or common way people are writing javascript from a custom control? (I'm not talking about a user control here!!, custom control/Class!) I also want to keep any indentation for readability once it's spit out/rendered on the client when viewing source.

  • Tell me again why we need both .NET and Windows? Why can't Windows morph into the CLR?

    - by le dorfier
    The same way DOS morphed into Windows? We seem to have ended up supporting and developing for three platforms from Microsoft, and I'm not sure where the boundaries are supposed to lie. Why can't the benefits of the CLR (such as type safety, memory protection, etc.) be built into Windows itself? Or into the browser? Why an entirely other virtual machine? (How may levels of virtual machine indirection are we dealing with now? We just added Silverlight - and before that Flash - running inside the Browser running inside maybe a VM install...) I can see raw Windows for servers, but why couldn't there be a CLR for workstations talking directly to the hardware (or at least not the whole Windows legacy ball and chain)? (ooppp - I've got two questions here. Let's make this - why can't .net be built into Windows? I understand about backward compatibility - but the safety of what's in .NET could be at least optionally in Windows itself, couldn't it? It would just be yet another of many sets of APIs?) Factoid - I recall that one of the competitor architectures selling against MS-DOS on the IBM PC was UCSD-pascal runtime - a VM.

  • Checking Selected Radio Button after POST

    - by coffeeaddict
    I've been using ASP.NET controls which perform a lot of the manual for you. But I'm going back to the basics, what everyone else does. I'm using standard input tags. So for example if I have a radio button group and I select a button. When the form submits and does a POST back to whatever action="MyPage.aspx" then to grab and check the radio button's value that was selected is it always done like this below? <label><input type="radio" name="rbGroup" value='<%# ((Action)Container.DataItem).ID %>'/><%# ((Action)Container.DataItem).Name %></label> So here I'm appending the ID to the value. And then when it hits the page that my action specifies, I'm checking to see which was selected by trimming off and getting that ID from the value: string selection = Request.Form["rbGroup"]; string dbRecordIdSelected = int.Parse(selection.Substring(1)); so now I can check the id they selected...that is the ID of the db record that gave that selected radio it's name. Is that how you basically always check what radio was selected by checking the name/value pair that comes across for that selected radioButton group name? And then you can append stuff like IDs or whatever you want to grab and parse out to then do additional logic on the server-side once that header reaches the server and your specified page in the action attribute? The above code is not production code, just something to explain what I'm talking about.

  • Chat app vs REST app - use a thread in an Activity or a thread in a Service?

    - by synic
    In Virgil Dobjanschi's talk, "Developing Android REST client applications" (link here), he said a few things that took me by surprise. Including: Don't run http queries in threads spawned by your activities. Instead, communicate with a service to do them, and store the information in a ContentProvider. Use a ContentObserver to be notified of changes. Always perform long running tasks in a Service, never in your Activity. Stop your Service when you're done with it. I understand that he was talking about a REST API, but I'm trying to make it fit with some other ideas I've had for apps. One of APIs I've been using uses long-polling for their chat interface. There is a loop http queries, most of which will time out. This means that, as long as the app hasn't been killed by the OS, or the user hasn't specifically turned off the chat feature, I'll never be done with the Service, and it will stay open forever. This seems less than optimal. Long question short: For a chat application that uses long polling to simulate push and immediate response, is it still best practice to use a Service to perform the HTTP queries, and store the information in a ContentProvider?

  • Compiling 32-bit Program on VS 2008

    - by gordonwd
    I've been developing on VC++ 2003 on an XP PC but am now on Windows 7 and bought a cheap legal copy of VS 2008 to continue work on the same project. My product has to continue to run on customers' XP systems, so I'm strictly interested in a 32-bit executable. The first issue I ran into was the PRJ0003 error "spawning cl.exe". I had to add the path to this file to the VC++ Directories settings (it appears in both a bin\amd64 and bin\x86_amd64 directory, but I don't think it matters output-wise which I use?). The issue I now have (not counting a tedious cleanup to convert strcpy to strcpy_s, etc.) is that I'm not clear on whether I'm generating a 32-bit or 64-bit exe out of this. My project properties are set to a target of "Win32", so I assume that all is well. Is this correct? I have read some discussions about this, but it's never quite clear if they are talking about whether the compiler itself is running x64 vs. x86, or whether the compiled code is x64 vs. x86, and how this is differentiated. So am I doing the right thing to generate a 32-bit, Win32, x-86 program?

  • PDF reviewer in C# (ASP.NET/Silverlight?)

    - by Anders Holmström
    Hi. I'm essentially planning to mimic the comment functions on PDF files, but online. That is; a user should be able to log in and upload a PDF file, and then numerous different users should be able to add comments etc to this same file (and view the file, with comments, online). External libraries are ok. Free obviously preferred, but commercial ones are fine if they provide a lot of the needed functionality. Note that this is meant to be used in a commercial environment. Comments don't necessarily need to be able to be exported from the site. I.e. if the comments are just put as a layer on top of a PDF file (and not in the actual file) that's ok. But obviously the more export functionality the better. I have looked at a few libraries (using the related questions and google) and while I find some that seem to do sort of what I want I'm not sure they are the bee's knees plus I would like to do as much myself as possible. The three basic approaches I've thought of is: Use some sort of native PDF viewing and then just smack down a layer on top of it where you can move around comments etc. Convert PDFs to HTML and work from there. Problem here it would either require proper PDFs (e.g. non-scanned) or really good OCR which seems a bit tedious. Convert PDFs to images and work from there. I'm afraid this will create massive images however. We're talking PDFs that can be hundreds of pages. One option would of course to just display one PDF page (image) at a time. And last - should I look at Silverlight for this or go with ASP.NET? Ideas and input concerning this project are much appreciated.

  • How to use different providers for Linq to entities?

    - by Anders Svensson
    I'm trying to familiarize myself a bit more with database programming, and I'm looking at different ways of creating a data access layer for applications. I've tried out a few ways but there is such a jungle of different database technologies that I don't know what to learn. For instance I've tried using datasets with tableadapters. Using that I am able to switch data provider rather easily (by programming against the interfaces such as IDbConnection). This is one thing I would want to achieve. But I also know everyone's talking about LINQ, and I'm trying to get to know that a bit better too. So I have tried using Linq to Sql classes as the data access layer as well, but apparently this is not provider independent (works only for SQL Server). So then I read about the Entity Framework (which just as Linq to SQL apparently has gotten its share of bashing already...). It's supposed to be provider independent everybody says, but how? I tried out a tutorial to create an entity data model, but the only providers to choose from were SQL Server/Express. Just for learning purposes, I would like to know how to use the entity framework with MS Access/OleDb. Also, I would appreciate some input on what is the preferred database technology for data access. Is it LINQ still after all the bashing, or should you just use datasets because they are provider independent? Any pointers for what to learn would be great, because it's just too much to learn it all if I'm not going to use it in the end...!

  • Looking forward to a programming future but confused where to start.

    - by Kraivyne
    Hi there, I am very new to this site and to programming. I started doing some basic programming with python a few weeks ago and recently, messing around with Java basics. My main problem is that I am completely overwhelmed and haven't got the slightest clue where I should be starting. I want to learn programming because I really enjoy doing it, the simple applications that I have managed to conjure up put a smile on my face. My plan is to eventually (by eventually I'm talking about 6 years+) go into games programming. I have been informed that C++ is the best way to go about this but haven't got the slightest clue what book/sight is optimal for someone who is still learning the very basics. These are my questions: I have been to the Definitive C++ Book Guide but am still unsure which book is best to start of with. Should I stick with Python or Java instead of moving on to C++? Is there any advice you would give to a beginner programmer? Thanks again for all your help.

  • .htaccess redirect noticably increasing load time

    - by GTCrais
    I set up a SEF link via .htaccess RewriteRule to one of the articles on my website just to see how that works, and it does work but it considerably increases the load time of that particular page. On average the articles (including the one I'm talking about, when not using the rewrite rule) load in about 1.3 seconds. With the rewrite rule, the load time is 3.3 seconds on average until the page displays, and the loader thingy in the firefox tab keeps spinning for another 2 seconds. I have WAMP setup on my computer, and the website is being accessed through no-ip.com. Here is the .htaccess config (very simple, as you can see): Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^o-sw-liji /NewSWL/o-nama.php?body=o-sw-liji In httpd.conf I have this (somewhere I read this might affect the load time for some reason - searching for files through all the directories or something, I don't remember exactly what I read): <Directory /> Options None AllowOverride None Order deny,allow Deny from all </Directory> DocumentRoot "Z:/Program Files (x86)/wamp/www/" <Directory "Z:/Program Files (x86)/wamp/www/"> Options None AllowOverride All Order allow,deny Allow from all </Directory> Any ideas why .htaccess redirect increases the load time by so much? UPDATE: so I put a session based counter in the "o-nama.php" script. Apparently when I access the web via the 'normal' link i.e. 'o-nama.php?body=o-sw-liji', the counter increases by one, as it should - it's one page load. But when the page is accessed through the redirected link, i.e. 'o-nama/o-sharewood-liji' the counter increases by 6-8, which naturally makes the load time a lot longer, since it's loading the same page for 6-8 times. I have no idea why this is happening. Any help is appreciated.

  • How can I make a new CTP (CakePHP) file in NetBeans?

    - by John Isaacks
    I have found a lot of info about adding CTP file support for NetBeans, but this is usually talking about code highlighting and treating a ctp file like a php file. This can be done at: Tools - Options - Miscellaneous - Files I have done this. However, when I try to create a NEW ctp file. I do not have the option. I tried going to Tools -> Templates to add a ctp template. There is no "new" button just an "add" button that looks for a file. I created a file on my desktop called cake_template.ctp on my desktop. I added it to the PHP templates in the template manager. I called the template "PHP Cake Template". Still when I go to create a new file, the option is not there. I restarted NetBeans, still the same. I just want to create a new .ctp file, it shouldn't be this difficult. Does anyone know how? I am using version 6.9.1

  • Issues with an image link

    - by user1462362
    Two days ago I spontaneously bought myself a domain. The day before that, I hardly even knew what a domain really was. Since then, I've been trying to teach myself HTML for the very first time. Basically what I'm trying to say is, I'm very new - and will probably be poor in my explanations. I just succeeded in making an 'image-button', sorta. It's where I make a button-like image and then use it as navigation on my website (just like a regular link). My issue is that the link 'border' itself is bigger than the image, so you can press an inch outside the image itself and it will work. How do I make the invisible link 'border' the same size as the button? This is my site: http://www.djeveln.com On the test page (djeveln.com/test) is where I test things. There's the button I'm talking about, in case you can't understand my explanation very well. Here's my HTML: Here is the CSS I use for the image position and size: img.TestButton { /* Dette linker til selve størrelsen av knappen (bildet)*/ position: absolute; width: 100px; height: 75px; top: 400px; right: 250px; } Hope you can help me! :P

  • Storing large json strings to database + hash

    - by Guy
    I need to store quiete large JSON data strings to the database. I am using gzip to compress the string and therefore BLOB MySQL data type to store it. However, only 5% of all the requests contain unique data and only unique data ought to be stored to the database. My approach is as follows. array_multisort data (array [a, b, c] is virtually the same as [a, c, b]). json_encode data (json_encode is faster than serialize; we need string array representation for the step 3). sha1 data (slower than md5, though less possible the collisions). Check if the hash exists in the database. 5.1 yes – do not insert the data. 5.2. no – gzip the data and store it along the hash. Is there anything about this (apart from storing JSON data to the database in the first place) that sounds fishy or should be done a different way? p.s. We are talking about a database with roughly 1kk unique records being created every month.

  • java.awt -- when java outputs an image to my monitor (screen), where is the file that is output to the monitor card?

    - by user1405870
    Suppose that I am drawing a set of images using java graphics objects. Suppose that I java is outputting these images to my monitor. Where is the file or files that are sent to the monitor card (the graphical representation files). How can I take this file and save it to disk, or how can I take this file and write it to an array, or how can I take these files and combine the results of their output (to the monitor) into a single file for saving? I don't want to use a screen shot feature, I want to be able to redirect (xor capture also) the output to the monitor to some sort of byte-stream. I note that monitors are much better than semaphores, when you are talking about display capabilities; I don't need a counter example. I might not be asking the correct question. It might be that I want to capture the file while it is still in User Space, before it is put into 'Device Space'. I would like to try and capture the byte stream so that I can convert it to MPEG-4 format. I either need a streaming output from the MPEG-4 converter, coming from the streaming input, or else, I need to take static images at discrete times and convert the images. What format will the output from User Space be in? What format will the Device Space output be in? Try to keep speculation to a minimum. http://docs.oracle.com/javame/config/cdc/opt-pkgs/api/jsr927/index.html I guess that Java has made a means of displaying AWT objects on a television screen. Thank you. Ryan Zoerner

  • Writing all the html of a document with jquery instead of in the page body?

    - by Robert
    I'm a UI person currently working on a web application, where most of the people I work with are back end developers. I'm currently at a disagreement with them about whether or not the above is a prudent thing to do. This application doe use quite a bit of JavaScript, and wouldn't even work without it unfortunately. This being the case, One of the back end developers that I'm working with is claiming that pages could and even SHOULD be build completely with JavaScript or jquery. This caught me completely off guard. We're talking about div tags, lists, background images and text here. I'm trying to explain to him that this isn't the right way to do things at all, and from a best practices perspective: content(html) should be separate from presentation(css), and behavior(script etc.). I know that it's possible to write html in jquery, although I haven't done it, but am I wrong in my thinking that this isn't the way things should be done. Is it even possible to write ALL the code with jquery? would love to hear any thoughts either way, as I will be discussing this with him again tomorrow.

    - by EugeneP
    table A and B need to have 1:M relationship a and b are added during application runtime, so A created, then say 4 B's created. Each B instance has to come in order, so that I could later extract them in the same order as I added them. The app will be a web-app running on Tomcat, so 10 instances may work simultaneously. So my question are: 1) How to preserve inserting order, so that I could extract B instances that A references in the same order as I persisted them. That's tricky, because we add to a Collection and then it gets saved (am I right?). So, it depends on how Hibernate saves it, what if it changes the order in what we added instances? I've seen something like LIST instead of SET when describing relationships, is that what I need? 2) How to add a 3-rd column to B so that I could differentiate the instances, something like SEX(M,F,U) in B table. Do I need a special table, or there's and easy way to describe constants in Hibernate. What do you recommend? 3) Talking about concurrency, what methods do you recommend to use? There should be no collisions in the db and as you see, there might easily be some if rows are not inserted (PK added) right where it is invoked without delays ?

  • Why isn't my leak detected by Xcode Intrumensts?

    - by Arlaharen
    I am trying to analyze some code of mine, looking for memory leaks. My problem is that some of my objects are leaking (at least as far as I can see), but the Leaks tool doesn't detect the leaks. My guess is that some iPhone OS object still holds pointers to my leaked objects. The objects I am talking about are subclasses of UIViewController that I use like this: MyController *controller = [[MyController alloc] initWithNibName:@"MyController" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; When these objects are no longer needed I do: [self.navigationController popViewControllerAnimated:YES]; Without a [controller release] call right now. Now when I look at what objects that gets created I see a lot of MyController instances that never gets destroyed. To me these are memory leaks, but to the Leaks tool they are not. Can someone here tell me if there is some way Instruments can tell me what objects are pointing to my MyController instances and thereby making them not count as memory leaks? Or better yet, tell me why these leaks are not detecetd.
