• How does UIImage work in low-memory situations?

  - by kubi

  According to the UIImage documentation: In low-memory situations, image data may be purged from a UIImage object to free up memory on the system. Does anyone know how this works? It appears that this process is completely transparent and will occur in the background with no input from me, but I can't find any definitive documentation one way or the other. Second, will this data-purge occur when the image is not loaded by me? (I'm getting the image from UIImagePicker). Here's the situation: I'm taking a picture with the UIImagePickerController and and immediately taking that image and sending it to a new UIViewController for display. Sending the raw image to the new controller crashes my app with memory warnings about 30% of the time. Resizing the image takes a few moments, time that I'd rather not spend if there's a 3rd option available to me.

• WinForms prints to default printer even if it's not available/connected

  - by Valentein

  How can I determine if printer is connected? Typically this application prints to the default printer but in some cases that printer may not be available. If so I don't want the job sent to it's queue but rather printed to another available printer. I understand the PinterSettings.InstalledPrinters property. Does PrintDocument.PrinterSettings.IsValid return false if a printer is not available? Does WPF provide this kind of functionality? My problem is different than Printing problem in C# windows app - Always prints to default printer

• Best package for basic web-based file manager

  - by alchemical

  I'm looking for a basic web-based file management application. It must have an affordable price, and fairly easy installation would be a plus. ASP.Net / IIS based would be easiest for me to work with. Basically, I'd like it to create a secure web site where myself and a few people can exchange various types of files, etc. I'm looking for a package I can install on my own server rather than a web-based service, as I think I can get more space at a good price point this way. I could go custom coding, but I figure this is such a generic need, there must be something already mature out there at a decent price. What has worked best for you?

• Is it a bad idea if equals(null) throws NullPointerException instead?

  - by polygenelubricants

  The contract of equals with regards to null, is as follows: For any non-null reference value x, x.equals(null) should return false. This is rather peculiar, because if o1 != null and o2 == null, then we have: o1.equals(o2) // returns false o2.equals(o1) // throws NullPointerException The fact that o2.equals(o1) throws NullPointerException is a good thing, because it alerts us of programmer error. And yet, that error would not be catched if for various reasons we just switched it around to o1.equals(o2), which would just "silently fail" instead. So the questions are: Why is it a good idea that o1.equals(o2) should return false instead of throwing NullPointerException? Would it be a bad idea if wherever possible we rewrite the contract so that anyObject.equals(null) always throw NullPointerException instead?

• Java "constant string too long" compile error. Only happens using Ant, not when using Eclipse

  - by Allan

  I have a few really long strings in one class for initializing user information. When I compile in Eclipse, I don't get any errors or warnings, and the resulting .jar runs fine. Recently, I decided to create an ant build file to use. Whenever I compile the same class with ant, I get the "constant string too long" compile error. I've tried a number of ways to set the java compiler executable in ant to make sure that I'm using the exact same version as in Eclipse. I'd rather figure out how to get the same successful compile I get in Eclipse in Ant than try to rework the code to dynamically concatenate the strings.

• C#: Dynamically instantiate different classes in the same statement?

  - by C. Griffin

  Here is a simplified version of what I'm trying to do: Without having multiple if..else clauses and switch blocks, can I mimic the behavior of Javascript's eval() shudder to instantiate a class in C#? // Determine report orientation -- Portrait or Landscape // There are 2 differently styled reports (beyond paper orientation) string reportType = "Portrait"; GenericReport report; report = new eval(reportType + "Report()"); // Resolves to PortraitReport() The need stems from the fact that I have 6 types of Crystal Reports (that do the same thing, but look drastically different) for 50 states. There are 3 styles each, rather than entertain the notion of a giant switch block with nested if..else statements determining which of 900 reports to use, I was hoping for an eval-like solution.

• ASP.NET MVC View Engine Comparison

  - by McKAMEY

  EDIT: added a community wiki to begin capturing people's experience with various View Engines. Please respectfully add any experiences you've had. I've been searching on SO & Google for a breakdown of the various View Engines available for ASP.NET MVC, but haven't found much more than simple high-level descriptions of what a view engine is. I'm not necessarily looking for "best" or "fastest" but rather some real world comparisons of advantages / disadvantages of the major players (e.g. the default WebFormViewEngine, MvcContrib View Engines, etc.) for various situations. I think this would be really helpful in determining if switching from the default engine would be advantageous for a given project or development group. Has anyone encountered such a comparison?

• How is Entity Framework 4's POCO support compared to NHibernate?

  - by Kevin Pang

  Just wondering if anyone has had any experience using Entity Framework 4's POCO support and how it stands up compared to NHibernate. If they're the same, I'd be very interested in making Entity Framework 4 my ORM of choice if only because it would: Support both data first AND object first development Have a robust LINQ provider Be easier to pitch to clients (since it's developed by Microsoft) Come baked into the .NET framework rather than requiring 8 dlls to get up and running In other words, are there any major shortcomings to EF4? Does it support all of the basic functionality NHibernate supports (lazy-loading, eager-loading, 1st level caching, etc.) or is it still rough around the edges? Is the syntax for setting up the mappings as easy as NHibernate and/or Fluent NHibernate? Edit: Please don't bring up the vote of no confidence. That was ages ago and dealt with some serious shortcomings of EF1 that really don't seem to apply anymore to EF4.

• Best practices in ASP.Net code behind pages.

  - by patricks418

  Hi, I am an experienced developer but I am new to web application development. Now I am in charge of developing a new web application and I could really use some input from experienced web developers out there. I'd like to understand exactly what experienced web developers do in the code-behind pages. At first I thought it was best to have a rule that all the database access and business logic should be performed in classes external to the code-behind pages. My thought was that only logic necessary for the web form would be performed in the code-behind. I still think that all the business logic should be performed in other classes but I'm beginning to think it would be alright if the code-behind had access to the database to query it directly rather than having to call other classes to receive a dataset or collection back. Any input would be appreciated.

• Are there any FreeRTOS interpreted language libraries available?

  - by Great Turtle

  I work for a company that created firmware for several device using FreeRTOS. Lately our request for new features has surpassed how much work our firmware engineers are capable of, but we can't afford to hire anyone new right now either. Making even tiny changes requires firmware people to go in and modify things at a very low level. I've been looking for some sort of interpreted language project for FreeRTOS that would let us implement new features at a higher level. Ideally I would like to get things eventually so the devices become closer to generic computers with us writing drivers, rather than us having to implement every feature ourselves. Are there any FreeRTOS projects that interpret java, python or similar bytecode? I've looked on google, but since I'm not a firmware engineer myself I'm not sure if I'm looking for the right keywords. Thanks everyone

• Jquery Randomizing within Categories

  - by David Chase

  Hi, so here is my question in a situation if you will. i have 6 items in div classes which correspond to 3 categories something like this class ="boat" class ="car" class ="bike" class ="blueboat" class ="redcar" class ="greenbike" so is there a jquery/javascript approach with .addClass where when someone clicks on the button "Randomize" it addClass .mine to each one of the 3 categories ie blueboat.mine and redcar.mine and bike.mine but not boat or car or greenbike because they are in the same category? or another situation rather than .addClass use a jquery/javascript so when "Randomize" is clicked to randomly show 3 out of 6 items one in each category of boat,car,bike and hide the rest blueboat,redcar,greenbike. in this situation all 6 items are on the page when document is ready but with the randomize only 3 are left one from each category. please let me know if anyone has any ideas or needs further clarification any help is greatly appreciated. thank you -david

• Linker problem linking boost in Visual Studio 2008

  - by Tobias Langner

  Hi, I have a rather obscure linking problem in Visual Studio 2008. The linker error message is: "LNK1104: cannot open file 'boost_thread-vc90-mt-gd-1_38.lib'". All pathes and dependencies are set. What I noticed though is that Visual Studio misses boost_thread-vc90-mt-gd-1_38.lib and not libboost_thread-vc90-mt-gd-1_38.lib (notice the lib at the beginning of the file name). I added the .lib as libboost_thread-vc90-mt-gd-1_38.lib to the project and it appears as libboost_thread-vc90-mt-gd-1_38.lib in the command line. Why does Visual Studio the beginning of the file name?

• Javascript incapable of getting element's max-height via element.style.maxHeight

  - by Zane

  I am making a simple accordion menu in javascript. I'd like to be able to set the compact and expanded heights for the elements via the css max-height and min-height values. For some reason, when I try to retrieve the min-height and max-height of the elements in javascript for animation purposes, I get an empty string rather than, for instance, "500px" like it should. The max-height value is set in css, e.g. #id { min-height: 40px; max-height: 500px; } is all set up, but when I put a debugging mechanism in my javascript such as alert( item.style.minHeight ); it pops up an empty alert box. This happens in Firefox 3.6.2 and IE 8. Does anybody know why javascript refuses to be able to get an element's minHeight and maxHeight?

• .DBML file and LINQ to SQL

  - by Rishabh Ohri

  In my DBML file I have mapped some tables and stored procedures, and the stored procedures return type is ISingleResult . T is some mapped table. But I want to take the data into my own created entities rather than LINQ to SQL created entites. The entites created by me are also the same as the mapped table entities and their use lies when we send data across the a web service. So , how can I proceed by creating a wrapper around the DBML file so that I always get data in my own created entites.

• 301 versus inline rewrites

  - by Kristoffer S Hansen

  I'm in the process of adding 'pretty' URLs to an existing CMS, the menu is auto generated and the new 'pretty' URLs are to be handled independently as a seperate module. The auto-generated menu allways has URLs that look like this index.php?menu_id=n which ofcourse we would like to see as eg. /news or /products I'm currently at the point where I have to decide if I'm going to rewrite all output of the current system or simply put in a hook where I redirect to the 'pretty' URL. To put it differently, should i connect to the database, fetch all 'pretty' URLs, run through the existing output from WYSIWYG's, news modules, forums etc. and do some str_replace or other string manipulation (which I think would be a rather tedious and boring process), or should I simply hook in and throw a 301 redirecting index.php?menu_id=3 to /news will Google (or other search engines) penalize me for having 301's in the menus?

• I've only programmed in AS3; What's the easiest practice in Flash CS4 to create simple animations?

  - by Zando

  So I've been using Flash for awhile, but rarely ever use the authoring tool. I want to create a quick little slideshow in which a user clicks buttons, and assets on the screen fade in an out as you move from slide to slide. I don't want to do this programatically...what's the quickest route to go about doing this, with using some AS3 but primarily relying on CS4's authoring tools? I remember when I first learned flash, years ago, you placed elements on stage and stretched them out over multiple frames. That seems like a lot of work...I'd rather just have, say, 10 total frames, each frame being a step in the slideshow, and each click of the next button going to that next frame, with each frame having its own animations.

• Universal iPhone/iPad application debug compilation error for iPhone testing

  - by andybee

  I have written an iPhone and iPad universal app which runs fine in the iPad simulator on Xcode, but I would now like to test the iPhone functionality. I seem unable to run the iPhone simulator with this code as it always defaults to the iPad? Instead I tried to run on the device and as it begins to run I get the following error: dyld: Symbol not found: _OBJC_CLASS_$_UISplitViewController Referenced from: /var/mobile/Applications/9770ACFA-0B88-41D4-AF56-77B66B324640/Test.app/Test Expected in: /System/Library/Frameworks/UIKit.framework/UIKit in /var/mobile/Applications/9770ACFA-0B88-41D4-AF56-77B66B324640/Test.app/TEST As the App is built programmatically rather than using XIB's, I've split the 2 device logics using the following lines in the main.m method: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate_Pad"); } else { retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate_Phone"); } From that point forth they use different AppDelegates and I've checked my headers to ensure the UISplitView is never used nor imported via the Phone logic. How do I avoid this error and is there a better way to split the universal logic paths in this programmatically-created app?

• Uploading images to a PHP server from Android

  - by Samuh

  I need to upload an image to a remote PHP server which expects the following parameters in HTTPPOST: *$_POST['title']* *$_POST['caption']* *$_FILES['fileatt']* Most of the internet searches suggested either : Download the following classes and trying MultiPartEntity to send the request: apache-mime4j-0.5.jar httpclient-4.0-beta2.jar httpcore-4.0-beta3.jar httpmime-4.0-beta2.jar OR Use URLconnection and handle multipart data myself. Btw, I am keen on using HttpClient class rather than java.net(or is it android.net) classes. Eventually, I downloaded the Multipart classes from the Android source code and used them in my project instead. Though this can be done by any of the above mentioned methods, I'd like to make sure if these are the only ways to achieve the said objective. I skimmed through the documentation and found a FileEntity class but I could not get it to work. What is the correct way to get this done in an Android application? Thanks.

• How to mock protected virtual members with Rhino.Mocks?

  - by Vadim

  Moq allows developers to mock protected members. I was looking for the same functionality in Rhino.Mocks but fail to find it. Here's an example from Moq Quick Start page how to mock protected method. // at the top of the test fixture using Moq.Protected() // in the test var mock = new Mock<CommandBase>(); mock.Protected() .Setup<int>("Execute") .Returns(5); // if you need argument matching, you MUST use ItExpr rather than It // planning on improving this for vNext mock.Protected() .Setup<string>("Execute", ItExpr.IsAny<string>()) .Returns(true); Let me know if I'm chasing something that doesn't exit.

• Modal View Controller Undesirably Hides Tab Bar

  - by Kevin Sylvestre

  I am working on an application that requires user authentication to access a profile. The profile section is located solely under one tab (and all others tabs do not require authentication). I currently present a authentication view controller modally (and then dismiss on success) when the user selects the profile tab. However, this approach prevents the user from deciding not to register / login (that is, all tabs are hidden once the authentication screen is presented modally). I don't want the user to be able to dismiss the modal view controller, but rather have it modal only for the profile tab. Is this possible? Can I have tabs visible while having a modal view controller? What is the best approach here. Thanks.

• Determining the hostname/IP address from the MX record in PHP

  - by pmmenneg

  Hi there, have a basic email domain validation script that takes a user's email domain, resolves the IP address from that and then checks that against various published blacklists. Here is how I am determining the IP: $domain = substr(strchr($email, '@'), 1); $ip = gethostbyname($domain); The problem is that some email address domains, such as [email protected], use an MX record rather than an A record, so using gethostbyname('alumni.example.net') will fail to resolve. I know when a user's email is using an MX in the email itself by using the PHP checkdnsrr function, but once at that stage am a little stuck as to how to proceed. In theory, I could parse out the 'root' domain, i.e. 'example.net' and check it, but I've not found reliable regex that can handle this task when the user could easily have an email the format of [email protected]... So, any suggestions on how to best tackle this??

• xcode build to iphone chooses old invalid provisioning profile

  - by sapatos

  I've just gone through some pain with iphone and xcode upgrades and keychain failures etc and decided to uninstall xcode completely and re-install. This fixed my keychain issues however the project I am working on appears to be linked to an old invalid provisioning profile. I've deleted the profile from "Provisioning Profiles" in organiser, and removed it from Provisioning on the Iphone section of Organiser. However when I build an go with the iphone sdk rather than simulator i get the pop up "codesign wants to sign using key "OldKey" in your keychain". It appears the actual app is associated with the old key and I can't seem to find how to point it to the new valid one. Crazy thing is at some point I managed to get it to work and install but the application crashed and won't open. I've not managed to get it to install again. Any ideas?

• Deeplinking using GWT History Token within a Facebook iFrame Canvas

  - by Stevko

  I would like to deep link directly to a GWT app page within a Facebook iFrame Canvas. The first part is simple using GWT's History token with URLs like: http://www.example.com/MyApp/#page1 which would open page1 within my app. Facebook Apps use an application url like: http://apps.facebook.com/myAppName which frames my Canvas Callback URL http://www.example.com/MyApp/ Is there a way to specify a canvas callback url (or bookmark url) which will take the user to a specific page rather than the index page? Why? you may ask. Besides all the benefits of deep links... I want the "Go To Application" url to take users to an index page w/ marketing material (the canvas callback url) I want the "Bookmark URL" to take (likely returning) users to a login page and bypass downloading the marketing content (and that huge SWF file).

• CUDA compare arrays

  Hello. Trying to make an app that will compare 1-to-multiple bitmaps. there is one reference bitmap and multiple other bitmaps. Result from each compare should be new bitmap with diffs. Maybe comparing bitmaps rather as textures than arrays? My biggest problem is making kernel accept more than one input pointer, and how to compare the data.. extern "C" __global__ void compare(float *odata, float *idata, int width, int height) works and following does not (i call the function with enough params) extern "C" __global__ void compare(float *odata, float *idata, float *idata2, int width, int height)

• Rate limiting Django admin login with Nginx to prevent dictionary attack

  - by shreddies

  I'm looking into the various methods of rate limiting the Django admin login to prevent dictionary attacks. One solution is explained here: simonwillison.net/2009/Jan/7/ratelimitcache/ However, I would prefer to do the rate limiting at the web server side, using Nginx. Nginx's limit_req module does just that - allowing you to specify the maximum number of requests per minute, and sending a 503 if the user goes over: http://wiki.nginx.org/NginxHttpLimitReqModule Perfect! I thought I'd cracked it until I realised that Django admin's login page is not in a consistent place, eg /admin/blah/ gives you a login page at that URL, rather than bouncing to a standard login page. So I can't match on the URL. Can anyone think of another way to know that the admin page was being displayed (regexp the response HTML?)
