• Moving UITableView row to top of list when selected

  - by Max Kilgore

  I am sure this is an easy thing to do. I am very new to objective C (picked up a job the boss was going to outsource) and could use all the help I can get. Just point me in the right direction here. Basically what I want to set up is this: I have a list of phone numbers that expands to as many rows as needed. I have no problem populating and the list works fine, but I would like for all of the recently selected items in the list to be more easily accessible at the top. So, whenever the user "didSelectRowAtIndexPath", I would like the row to move to the top. I just KNOW this is super simple... but I haven't found the solution yet. No hurry. I am just trying to figure things out on my own. Thanks in advance!

• iOS sdk question: how do I cast a UIView to a UIImage View (alternativly how do I get a UIImageView from a GestureRecognzer?)

  - by user439299

  Desired end result: user taps a UIImageView and the image changes to another image (a subsequent tap returns the image to the original state) Problem: I add a (unique) selector to a bunch of UIImageViews (in an array) and point the action at the same function - let's call this function imageTapped: for now. Here is my code so far: -(void)imageTapped:(UITapGestureRecognizer *)tapGesture { UIImageView *view = tapGesture.view; // rest of code... } This code actually works fine but gets a warning when I run it: "Incompatible objective c types initilizing 'struct UIView *', expected 'struct UIImageView *' Any way to get rid of this? Not sure how casting works in objective c... primitive types seem to work fine such as (int)someFloat works fine but (UIImageView)someUiView doesn't work. Like I said, code works alright when I run it but would like to get ride of the compiler warning. Any help would be awesome.... I am very new to objective c (or any non java language for that matter) so be gentle. Thanks in advance.

• Rspec > testing database views

  - by Sean McCleary

  How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

• Scheduled cron job to check for pending activity

  - by luckytaxi

  Using PHP ... This is for my personal use so I'm thinking maybe 3-4 emails a day. I'm at a point where I can send an email to a dedicated email address where my script parses the message and stores it into a DB. Now, I need to figure out the best way to check the records in the DB for any upcoming task. I feel like I'm missing something, maybe like a trigger field as to when a reminder should go out. However, that's not a concern to me at the moment since I'll just send an alert 15 mins prior to the due date. Question is, shoudl I run a cron job that queries the DB every minute? I take it the query will have to say something like "select all tasks that is due within 15 minutes."

• Why are regular expressions such a complicated, cryptic mess?

  - by steffenj

  Often when I see regular expressions, I only see a total mess of characters. Why does it have to be this way? I guess what I really want to know is: are there alternatives to regular expressions that basically do the same thing but are implemented in a human readable language? [UPDATE] Thanks for all the great responses and inspiration! I wanted to highlight this particular link which shows how a (working) alternative would look like, which may also be a good starting point for learning or "simple" regex expressions. But you also quickly get a feel for the verbosity tradeoff.

• Struts 2: redirect-action ? From on page to another and back again.

  - by Stephan

  Hello, i have a jsp page that has a submit button. This button is linked with another jsp page. So lets assume my stuts file looks like this: B.jsp So now the submit button being on page "A.jsp" will take me to B.jsp. This works. The problem is that i want to do the following: press on the submit button on page A.jsp , go to B.jsp where i will press again a button and go back to A.jsp . The problem is that to page B.jsp go many pages, so B.jsp has to know when pressing the submit button to which page will take me back , in this case A.jsp again. So in a few words, B.jsp has to know from which page i came from so that i can go back again by pressing a submit button (this could be a parameter that would be sent back to A.jsp again, but does not really matter at the current point) A.jsp - B.jsp - A.jsp C.jsp - B.jsp - C.jsp

• ASP.NET jQuery Ajax posting forms

  - by Sir Psycho

  Hi, I can't seem to get the jQuery.ajax() function posting back any of my asp.net generated form controls. I've put a break point on the server side and there aren't any values. Is there a way around this or do I have to build up a list of what I want sent back? Another question slightly off topic, but it seems that although jQuery is a great JS library, it doesn't seem to integrate too well with .net. Has anyone given up with jQuery to perform server side interaction and just gone with ms ajax implementation?

• Querying results on timestamp in mysql

  - by Tom

  Hi, I have series of records in a table called 'hits' and each record has the current_timestamp (ie. 2010-04-30 10:11:30) in a column called 'current_time'. What I would like to do is query these records and return only the records from the current month. I cannot seem to get this to work. I have tried a range of queries that don't work such as - Select * FROM hits WHERE MONTH(FROM_UNIXTIME(current_time)) = 4 I don't know if I am even on the right lines! Can anyone point me in the right direction? Cheers.

• What's the best way to do Ruby gemspec creation and dependency management?

  - by John Feminella

  Over the last few months, there have been a number of rapid developments in the state of Ruby dependency management and gem creation, to the point where I've been having trouble keeping up with everything. If I'm writing a new gem, what's the best tool for me to use to create my gemspec? Are there disadvantages of using this tool over competitors? I've used Bundler a few times on applications and for me it's been a lifesaver. Is the consensus that it is suitable for use with production apps? Are there quirks or idiosyncracies people should be aware of? Links to resources you've used and have found helpful would also be much appreciated.

• Problem with domain getting turned to IP address for https

  - by user229133

  I have a website that is using Windows Server 2003. The site is called https://mysite.com/ and at ip address 111.1.1.1. Now when I log into the site all my relative links that are generated using NavURL (<%# NavURL("Images/Menu/img.gif")%) are saying "http://111.1.1.1/Images/Menu/img.gif" instead of "https://mysite.com/Images/Menu/img.gif". This is causing an error because it needs to be secure. I'm sure there is a setting on the server somewhere to point to the name and not the ip, but I don't know where. Thanks for your help.

• CI controller function is ignored

  - by den-javamaniac

  Hi. I'm trying to pass through a CI tutorial (writing a simple forum) and I can't make a controller function called. To be more specific I have this in a controller: function __construct() { parent::Controller(); $this->load->helper('url'); } function index() { $data['title'] = "Wlcome to Gossip"; $data['heading'] = "Welcome to Gossip"; $data['query'] = $this->db->get('topic')->result(); $this->load->view('welcome', $data); } function topic() { echo 'testing...'; } and when I'm trying to access the /index.php/forum/topic/ uri it just prints out my index() function. Can any one point out what may cause the problem?

• How do C++ header files work?

  - by PulpFiction

  Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

• delphi finalizalization code in a DLL

  - by PA

  I am moving some functions to a shared DLL (I want to have some called as a Windows hook). The actual functions are currently in a unit, and it happens to have some initialization and some finalization code. I was initially thinking on doing a direct transformation from a unit to a library. So I moved the initialization code in between the main begin and end.. But then I realized I had no place to move the finalization code. I should create and register an special DLL entry point, instead. My question is. Can I leave the unit with all the functions and the initialization and finalization codes and just create a library stub that uses the unit? will the finalizationit be called?

• jQuery can't get if statement to work

  - by jstacks

  I'm looking help with an If Statement. I'm trying to finalize this horizontal scrolling I have and the last bit is to not just disable scrolling when the end is reached, but to also disable (well, change color) the scroll buttons at that point as well. And change back when they are scrollable again. http://jsfiddle.net/stfzy/83/ EDIT* I've updated the JQuery and have everything working except just one if statement: $('div#arrowL').click(function(){ if(index < 0 ){ //can't scroll $('div#arrowL').addClass('active'); } }); I need to add this class back when you can't scroll left anymore. And I think the issue is with the "index < 0" portion but I don't see what I need to change it to to get it to work. Any help is appreciated.

• Dump Hibernate activity to sql script file

  - by zeven

  Hi, I'm trying to log hibernate activity (only dml operations) to an sql script file. My goal is to have a way to reconstruct the database from a given starting point to the current state by executing the generated script. I can get the sql queries from log4j logs but they have more information than the raw sql queries and i would need to parse them and extract only the helpful statements. So i'm looking for a programatic way, maybe by listening the persist/merge/delete operations and accessing the hibernate-generated sql statements. I don't like to reinvent the wheel so, if anybody know a way for doing this i would appreciate it very much. Thanks in advance

• Writing different structs to a file in C++? [on hold]

  - by user58053

  I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

• C# change e-mail 'from' address to a user-provided one.

  - by Jeff

  We have an app that allows users to send e-mails from our system. It allows the user to specify their e-mail address, and gives them several standard templates to use as a starting point for their e-mail. When we send the e-mails, we use the address they provided as the 'reply-to', but the 'from' address of the e-mail (naturally) looks like our system (from '[email protected]'). Is there a way to change this without getting tangled up in spam filters or automatic blocking? We'd prefer not to confuse the recipient as to who actually composed the e-mail they've received.

• Apache crashes after installing mysqli

  - by Marco P.

  System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

• Turning user ID into name (seperate tables) in PHP

  - by mobile

  I am currently trying to display the username of people who i am following, the problem is that during the following process, only the ID of me and the person i'm following is stored. I've got it to the point where the ID's are displayed but i'd like to show the names hyperlinked. $p_id is the profile ID. Here's what I've got: $following = mysql_query("SELECT `follower`, `followed` FROM user_follow WHERE follower=$p_id"); I am following: <?php while($apple = mysql_fetch_array($following)){ echo '<a href="'.$apple['followed'].'">+'.$apple['followed'].'</a> '; }?> The usernames are in a different table "users" under the field "username" - I need them to match up with the ID's that are currently displayed, and be displayed. Any help appreciated, thanks guys

• base pointer to derived class

  - by Jay

  Suppose there are Base class and Derived class. Base *A = new Base; Here A is a pointer point to Base class, and new constructs one that A points to. I also saw Base *B = new Derived; How to explain this? B is a pointer to Base Class, and a Derived class constructed and pointed by B? If there is a function derived from Base class, say, Virtual void f(), and it's been overridden in Derived class, then B->f() will invoke which version of the function? version in Base class, or version that overridden in Derived Class. What if there is a new function void g()in Derived, is B->g() going to invoke this function properly? One more is, is int *a = new double; or int *a = new int; legal?

• What is a 'best practice' backup plan for a website?

  - by HollerTrain

  I have a website which is very large and has a large user-base. I am trying to think of a 'best practice' way to create a back up or mirror website, so if something happens on domain.com, I can quickly point the site to backup.domain.com via 401 redirect. This would give me time to troubleshoot domain.com while everyone is viewing backup.domain.com and not knowing the difference. Is my method the ideal method, or have you enacted better methods to creating a backup site? I don't want to have the site go down and then get yelled at every minute while I'm trying to fix it. Ideally I would just 'flip the switch' and it would redirect the user to a backup. Any insight would be greatly appreciated.

• Understanding a lighttpd.conf file?

  - by AP257

  Hi all, I've been given a lighttpd.conf that someone else wrote and need help working out how to serve it. I'm 90% of the way there but stuck... The index.html page appears, but links and CSS files don't point to the right place. To clarify, the links and CSS files are all pointing to a 'file:///' URL. So styles.css in the HTML header points to file:///html/styles.css, whereas it should be going to http://url.com/styles.css Maybe url.rewrite or url.redirect isn't working properly? server.document-root = "~/html" server.port = 28001 mimetype.assign = ( ".html" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" ) url.rewrite = ( "^(.*)/($|\?.*)" => "$1/index.html", "^(.*)/([^.?]+)($|\?.*)$" => "$1/$2.html" ) $HTTP["scheme"] == "http" { url.redirect = ( "^/platform/index.html$" => "/platform", "^/about/company.html$" => "/about/company",, ) }
