  • Who should call viewDidLoad on progammatically loaded views?

    - by Remus Rusanu
    When I need to load a view programatically I do the following: MyController* myController = [[MyController alloc] init]; [[NSBundle mainBundle] loadNibNamed:@"myNib" owner:myController options:nil]; // use my controller here, eg. push it in the nav controller This works fine, but my controller's viewDidLoad is never called. So I resorted to manually calling it after the loadNibNamed call, but it doesn't seem correct. I was expecting the framework to call the viewDidLoad on my behalf. Is this the right way or I'm missing something?

  • Examples of how to visualize a versioning system?

    - by Alex Gilbert
    My shop is trying to formalize the release management process for an OSS product we maintain. It's a sort of a web development framework/CMS kind of thing, as in it's a product that other projects are built on top of. This makes clear communication about the versioning system especially critical for developers that are using the tool. I'm hoping to find some examples of how best to graph this system so we can communicate it better internally and with outside developers. I know there are lots of standards and best practices around versioning, so I'm hoping this extends to some sort of visual vocabulary as well. As one example, there is a nifty graph at http://en.wikipedia.org/wiki/Versioning#Software_Versioning_schemes. Are there any guides out there on how these sorts of things should be designed?

  • Load vs Get in Nhibernate

    - by Quintin Par
    The master page in my web application does authentication and loads up the user entity using a Get. After this whenever the user object is needed by the usercontrols or any other class I do a Load. Normally nhibernate is supposed to load the object from cache or return the persistent loaded object whenever Load of called. But this is not the behavior shown by my web application. NHprof always shows the sql whenever Load is called. How do I verify the correct behavior of Load? I use the S#arp architecture framework.

    i will have the following set up: people will be sending text messages to a server, and that server will be forwarding the messages to other phone numbers i am not sure what kind of framework i should use. should i develop an SMS gateway and use AT commands? should i just try to somehow use AIM or GCHAT to capture and send SMS messages? would there be a different more suitable configuration? are there already developed frameworks that are free which i can use? for example i know that i can send an SMS to almost anyone through gchat or aim by sending a message to "+" and the number of the person. is this scalable and can i use it for my own benefit? any sms developers out there?

  • Can't get YUI animations to wait until the first has finished

    - by Andy Cairns
    Hi there, I have 3 animations that run when I load my page. A header descends from the top and a footer ascends from the bottom. Also, my main logo goes from fully transparent to fully opaque. I'm using the YUI framework for the animations. My problem is that they all happen at the same time. I'd like the header & footer animations to go at the same time but the logo to wait until the others have finished. setTimeout doesn't appear to work (the animation triggers immediately). I've also tried a while loop to wait until the currentFrame = a certain number but my loops seem to stop everything from working. Any help would be gratefully received. Thanks Andy

  • Open a PDF file in an external app on iPad

    - by Yuji
    I'd like to make my app to open a specified PDF by an external app of the user's choice on the iPad. How can I do that? Or, is there any open-source PDF reader framework available so that I can put it into my app? My situation in more detail: I'm thinking of porting to the iPad from OS X / rewriting from scratch for the iPad an app which manages lots of PDFs (journal articles, etc.), but I don't want to write the PDF reader part, because there are many good ones already out there; I don't want to reinvent the wheels. (You might say you shouldn't reinvent pdf management apps, but I'd like to make one as a front end to SPIRES, and there isn't one so far.) As the app would be a front end to a serious reading activity, UIWebView's pdf capability is not enough. Also, users of my app would have various preferences which app to use. That's the background behind my question. Thanks in advance!

  • Detect aborted connection during ASIO request

    - by Tim Sylvester
    Is there an established way to determine whether the other end of a TCP connection is closed in the asio framework without sending any data? Using Boost.asio for a server process, if the client times out or otherwise disconnects before the server has responded to a request, the server doesn't find this out until it has finished the request and generated a response to send, when the send immediately generates a connection-aborted error. For some long-running requests, this can lead to clients canceling and retrying over and over, piling up many instances of the same request running in parallel, making them take even longer and "snowballing" into an avalanche that makes the server unusable. Essentially hitting F5 over and over is a denial-of-service attack. Unfortunately I can't start sending a response until the request is complete, so "streaming" the result out is not an option, I need to be able to check at key points during the request processing and stop that processing if the client has given up.

  • Photo uploading via email

    - by Lee
    I'd like to be able to upload photos via email, which I've seen (and used) on eat.ly and meetups.jquery.com but I haven't been able to work out how to do this, does anyone have a solution? Essentially I believe the process should be something like this: 1) user adds picture to email on mobile device then send to a specific email address, say '[email protected]' 2) email server, cron job or something else looks at the senders address and tells it to add the attachement to that account 3) photo shows up on users profile page I run Apache servers, with MySQL, PHP, and a JQuery framework. I have email servers running Courier, and I missing anything?

  • How do I pass a DBNull value to a parameterized SELECT statement?

    - by Dan
    I have a SQL statement in C# (.NET Framework 4 running against SQL Server 2k8) that looks like this: SELECT [Column1] FROM [Table1] WHERE [Column2] = @Column2 The above query works fine with the following ADO.NET code: DbParameter parm = Factory.CreateDbParameter(); parm.Value = "SomeValue"; parm.ParameterName = "@Column2"; //etc... This query returns zero rows, though, if I assign DBNull.Value to the DbParameter's Value member even if there are null values in Column2. If I change the query to accommodate the null test specifically: SELECT [Column1] FROM [Table1] WHERE [Column2] IS @Column2 I get an "Incorrect syntax near '@Column2'" exception at runtime. Is there no way that I can use null or DBNull as a parameter in the WHERE clause of a SELECT statement?

  • How to log slow queries in shared hosting MySQL?

    - by tomaszs
    I have a shared hosting where I have my website and MySQL database. I've installed a open source script for statistics (phpMyVisites) and it started to work very slow lately. It's written using some kind of framework and has many PHP files. I know that to find slow queries I can use slow query log functionality in MySQL. But on this shared hosting I can not use this method because I can not change my.cnf. I don't want to change my statistics script to other and I don't want to mess around with all files of this script to find out where to put diagnostics code to log queries manually. I would like to do it without changes in PHP code. So my question is: How to log slow queries in these coditions?: Can't change my.cnf to enable slow query log Can't change statistics script to other Don't know how scrpt is written and where mysql commands are issued Can't ask my provider for slow query log Is there any method to do this in simple, easy, fast way?

  • .NET 3.5 SP1 prerequisite, MS giving the clients 4.0

    - by Matt Bridges
    I have been using an MSI to install a WPF application using the .NET Framework 3.5 SP1. I have set up .NET 3.5 as a prerequisite in the MSI, and what has been happening for ages is that when the user does not have .NET 3.5 SP1, the MSI first has them download and install that before resuming the installation of my application. Since yesterday when MS released .NET 4.0, when users don't have .net 3.5 SP1, the MSI is directing them to install 4.0 instead. What happens though, is that after they finish installing 4.0, the MSI still detects that they don't have 3.5, and directs them to the 4.0 install site again. So the user has 4.0, but the MSI doesn't ever get to installing my application. What do I have to change in my application? This seems like an error with how MS is handling the prerequisites either on their server or in the MSI in VS 2008.

  • Webwork actions, the lifecycle of variables declared in the action class.

    - by Sam
    Hi all, I'm using the webwork framework (JIRA plugin development) and was wondering about the lifecycle of the variables in the action class. I have a few private variables in the action class that are set when during the doDefault() method. These are used in the input view to set up jqGrid columns and then when the user has entered some data they click submit which puts the grid data into a hidden input. The next thing that happens is the doValidation() method is called before the doExecute(), which displays the input view if there are any errors. The problem is that the variables set up in the doDefault() method are now null. Can anyone explain to me how the lifecycle of variables works in the webwork actions? Cheers

  • Why addming permissions to an existing AppDomain has no effect?

    - by MainMa
    Hi, I have a following code which behaves strangely in .NET 4.0: // AppDomain is created, and permissions which were added to `sandboxPermissions` are added successfully. sandboxAppDomain = AppDomain.CreateDomain("SandboxDomain", null, appDomainSetup, sandboxPermissions, new[] { commonStrongName }); // Trying to add a new permission to an AppDomain which is already created. sandboxAppDomain.PermissionSet.AddPermission(new FileIOPermission(FileIOPermissionAccess.AllAccess, @"C:\Some\Path\Here")); // Setting breakpoint to this line: `permissions` contains every permission which was added to `sandboxPermissions`, but no trace of C:\Some\Path\Here related permission. var permissions = sandboxAppDomain.PermissionSet.ToXml(); Every permission added before creating an AppDomain is just here, as expected. But adding permissions after an AppDomain is created has no effect at all. There are no exceptions thrown (nor first-chance ones). What can it be? If the framework method (AddPermission) fails to do what it was expected to do, mustn't it throw an exception?

  • Pure HTML + JavaScript client side templating

    - by Dev er dev
    I want to have achieve something similar to Java Tiles framework using only client side technologies (no server side includes). I would like to have one page, eg layout.html which will contain layout definition. Content placeholder in that page would be empty #content div tag. I would like to have different content injected on that page based on url. Something like layout.html?content=main or layout.html?content=edit will display page with content replaced with main.html or edit.html. The goal is to avoid duplicating code, even for layout, and to compose pages without server-side templating. What approach would you suggest? EDIT: I don't need a full templating library, just a way to compose a pages, similar for what tiles do.

  • Extend TTPhotoViewController with custom TTPhotoView

    - by ggould75
    I have successfully integrated the three20 framework in my project, and I have extended the TTPhotoViewController to add some further functionality. Now I need to add some subviews to the TTPhotoView loaded by the TTPhotoViewController. In particular I would like to add that subviews after every TTPhotoView as been loaded. These subviews represents sensible area over the image so they should scale proportionally with the image. The user can tap a subview to get extra info about the image. I don't know how to implement this behavior. Should I extend the TTPhotoView and make sure that the TTPhotoViewController use this extended version instead of its TTPhotoView? Could someone point me to the right direction? Thank you

  • Consume restful webservice through web proxy

    - by Chico
    Hello, I'm trying to consume a restful webservice in java using the Apache Wink framework through my school web proxy requiring authentification ClientConfig clientConfig = new ClientConfig(); clientConfig.proxyHost("proxy.school.com"); clientConfig.proxyPort(3128); //nothing to set username and password :( RestClient client = new RestClient(clientConfig); Resource resource = client.resource("http://vimeo.com/api/v2/artist/videos.xml"); String response = resource.accept("text/plain").get(String.class); I've also tried to use the BasicAuthSecurityHandler but it seems to be used to authenticate directly to a web server, not the web proxy BasicAuthSecurityHandler basicAuthHandler = new BasicAuthSecurityHandler(); basicAuthHandler.setUserName("username"); basicAuthHandler.setPassword("password"); config.handlers(basicAuthHandler); It still fail with a HTTP 407 error code : Proxy Authentication Required. I've googled the best I could, nothing came up better to consume a webservice from a Java client through a web proxy, if someone has another idea, feel free to respond

  • How do I draw the desktop on Mac OS X?

    - by Dominic Cooney
    I want to draw the desktop on Mac OS X (Snow Leopard). Specifically, I want to achieve the same effect as running: /System/Library/Frameworks/ScreenSaver.framework/Resources/ ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background (If you’re not near your computer, this displays the screensaver where you would normally see your desktop background.) I know how to make a window without a border (by subclassing NSWindow and overriding initWithContentRect:styleMask:backing:defer: to set the window style to NSBorderlessWindowMask) and without a shadow (setHasShadow:NO.) I know that I can call setLevel:kCGDesktopWindowLevel or kCGDesktopIconWindowLevel to put my window below other windows (see question 418791.) However this isn’t exactly what I want, because a window at this level is still on top of the desktop icons. I want to be on top of the desktop background, but below the icons. My view is opaque. If there is a technique that clobbers the desktop background, that is OK.

  • BuiltIn Function to Convert from Hex String to Byte

    - by Ngu Soon Hui
    This question is similar to the one here. One can easily convert from hex string to byte via the following formula: public static byte[] HexStringToBytes(string hex) { byte[] data = new byte[hex.Length /2]; int j = 0; for (int i = 0; i < hex.Length; i+=2) { data[ j ] = Convert.ToByte(hex.Substring(i, 2), 16); ++j; } return data; } But is there a built-in function ( inside .net framework) for this?

  • Best implementation for MySQL replication with Rails 3?

    - by vonconrad
    We're looking at potentially setting up replication for our primary MySQL database, and while setting up the replication seems pretty straight-forward, the application implementation seems a bit murkier. My first idea would be to set up a master-slave configuration and RW-splitting, with all write queries (CREATE, INSERT, UPDATE) going to master, and all read queries (SELECT) going to slave. Having read up on it, it seems that there are essentially two options for how to implement this with our app: Using an independent middleware layer for all MySQL connections, such as MySQL proxy or DBSlayer. However, the former is in Alpha and the latter has limited documentation. Using a Ruby-based gem/plugin, such as Octopus to achieve RW-splitting in the framework. If we wanted to go with a master-slave setup, what you recommend moving forward? The other thought I've had was to use a master-master configuration, but am unsure about the implementation of such a setup. Thoughts?
