  • How can I find days between different paired rows?

    - by Anthony
    I've been racking my brain about how to do this in one query without PHP code. In a nutshell, I have a table that records email activity. For the sake of this example, here is the data: recipient_id activity date 1 delivered 2011-08-30 1 open 2011-08-31 2 delivered 2011-08-30 3 delivered 2011-08-24 3 open 2011-08-30 3 open 2011-08-31 The goal: I want to display to users a single number that tells how many recipients open their email within 24 hours. E.G. "Users that open their email within 24 hours: 13 Readers" In the case of the sample data, above, the value would be "1". (Recipient one was delivered an email and opened it the next day. Recipient 2 never opened it and recipient 3 waited 5 days.) Can anyone think of a way to express the goal in a single query? Reminder: In order to count, the person must have a 'delivered' tag and at least one 'open' tag. Each 'open' tag only counts once per recipient.

  • VC++ - Asynchronous Thread

    - by JVNR
    I am working on VC++ project, in that my application process a file from input path and generates 3 output "*.DAT" files in the destination path. I will FTP these DAT file to the destination server. After FTP, I need to delete only two output .DAT files the folder. I am able to delete those files, because there one Asynchronous thread running behind the process. Since the thread is running, while deleting it says, "Cannot delete, the file is used by another person". I need to stop that thread and delete the files. Multiple files can also be taken from the input path to process. Please help me in resolving this issue. Its very high priority issue for me. Please help me ASAP.

  • Is this plain stupid: GIT Sharing Via DropBox?

    - by yar
    I realize that there are similar questions, but my question is slightly different. I'm wondering whether sharing a bare repository via a synchronized DropBox folder on multiple computers would work for sharing code via GIT. Really what I want to know is: is sharing a GIT repo via DropBox (the repo gets updated on each person's local drive) the same as sharing it from one centralized location, e.g., via SSH, git or HTTP? Is this the same or different from sharing a GIT repo via a shared network drive? Note: This is not an empirical question: it seems to work fine. I'm asking whether the way a GIT repo is structured is compatible with this way of sharing. EDIT To clarify/repeat, I'm talking about keeping the GIT repository on DropBox as a bare repository. I'm not talking about keeping the actual files that are under source control in DropBox.

  • What magical thing could be killing my Drupal session and anywhere from 15-45 minutes of activity?

    - by jini
    I am using a standard Drupal install hosted on a LAMP stack. My settings.php has the following set: ini_set('session.gc_probability', 1); ini_set('session.gc_divisor', 100); ini_set('session.gc_maxlifetime', 200000); ini_set('session.cookie_lifetime', 2000000); my php.ini file has: session.gc_probability = 1 session.gc_divisor = 1000 session.gc_maxlifetime = 1440 Also I have checked that the safe mode is off so that my settings.php file is able to override main php.ini variables. Also since the person can get log out at 15 minutes, it is making me wonder whether php.ini has anything to do with it anyways. I have combed through my code and it seems to work fine on my local host however on server it is having issues. Where else can i possibly check?????

  • 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

  • PHP: Display comma after each element except the last. Using 'for' statement and no 'implode/explode

    - by Jonathan
    hi, so I have this simple for loop to echo an array: for ($i = 0; $i < count($director); $i++) { echo '<a href="person.php?id='.$director[$i]["id"].'">'.$director[$i]["name"].'</a>'; } The problem here is that when more than one element is in the array then I get everything echoed without any space between. I want to separate each element with a comma except the last one. I cant use 'implode' so I'm looking for another solution... Anyone?

  • Hibernate criterion Projection alias not being used

    - by sbzoom
    Do Hibernate Projection aliases even work? I could swear it just doesn't. At least, it doesn't do what I would expect it to do. Here is the java: return sessionFactory.getCurrentSession().createCriteria( PersonProgramActivity.class ).setProjection( Projections.projectionList().add( Projections.alias( Projections.sum( "numberOfPoints" ), "number_of_points" ) ).add( Projections.groupProperty( "person.id" ) ) ).setFirstResult( start ).setFetchSize( size ).addOrder( Order.desc( "numberOfPoints" ) ).list(); Here is the SQL that it generates: select sum(this_.number_of_points) as y0_, this_.person_id as y1_ from PERSON_PROGRAM_ACTIVITY this_ group by this_.person_id order by this_.number_of_points desc It doesn't seem to use the alias at all. I would think setting the alias would mean that "sum(this_.number_of_points)" would be aliased as "number_of_points" and not "y0_". Is there some trick I am missing? Thanks.

  • What to do with someone who can only use "the one true language"?

    - by Rob Wells
    G'day, How do you work with someone when they haven't been able to see that there is a range of other languages out there beyond "The One True Path"? I mean someone who hasn't grown up to realise that the modern software professional has a range of tools in his toolbox. Someone who has a well-equipped toolbox and then selects the best tool for the job at hand. The person who's knee jerk reaction is, for example, "We must do this is C++!" "Everything must be done in C++!" What's the best approach for these people? How do you open them up to the fact that "not everything is a nail." cheers,

  • MySQL table with similar column info - HELP!!!

    - by George Garman
    I have a DB with a table that is named "victim". The form that dumps the info into the table has room for two victims and therefore there is vic1_fname, vic1_lname, vic2_fname, vic2_lname, etc.. (business name, person first, person last, address, city, state, zip) a "1" and "2" of each. Now I want to search the DB and locate listed victims. This is what I have so far: $result = mysql_query( "SELECT victim.* FROM victim WHERE vic1_business_name OR vic2_business_name LIKE '%$search_vic_business_name%' AND vic1_fname OR vic2_fname LIKE '%$search_vic_fname%' AND vic1_lname OR vic2_lname LIKE '%$search_vic_lname%' AND vic1_address OR vic2_address LIKE '%$search_vic_address%' AND vic1_city OR vic2_city LIKE '%$search_vic_city%' AND vic1_state OR vic2_state LIKE '%$search_vic_state%' AND vic1_dob OR vic2_dob LIKE '%$search_vic_dob%' "); <table width="960" style="border: groove;" border=".5"> <tr><th colspan=10>You search results are listed below:</th></tr> <tr> <th>Case Number</th> <th>Business Name</th> <th>First Name</th> <th>Last Name</th> <th>DOB / Age</th> <th>Address</th> <th>City</th> <th>State</th> </tr> <?php while($row = mysql_fetch_array($result)) { ?> <tr> <td align="center"><?php print $row['vic_business_name']; ?></td> <td align="center"><?php print $row['vic_fname']; ?></td> <td align="center"><?php print $row['vic_lname']; ?></td> <td align="center"><?php print $row['vic_dob']; ?></td> <td align="center"><?php print $row['vic_adress']; ?></td> <td align="center"><?php print $row['vic_city']; ?></td> <td align="center"><?php print $row['vic_state']; ?></td> </tr> <?php } ?> </table> The info did not display in the table until I changed the table to this: <tr> <td align="center"><?php print $row['vic1_business_name']; ?></td> <td align="center"><?php print $row['vic1_fname']; ?></td> <td align="center"><?php print $row['vic1_lname']; ?></td> <td align="center"><?php print $row['vic1_dob']; ?></td> <td align="center"><?php print $row['vic1_adress']; ?></td> <td align="center"><?php print $row['vic1_city']; ?></td> <td align="center"><?php print $row['vic1_state']; ?></td> </tr> <tr> <td align="center"><?php print $row['vic2_business_name']; ?></td> <td align="center"><?php print $row['vic2_fname']; ?></td> <td align="center"><?php print $row['vic2_lname']; ?></td> <td align="center"><?php print $row['vic2_dob']; ?></td> <td align="center"><?php print $row['vic2_adress']; ?></td> <td align="center"><?php print $row['vic2_city']; ?></td> <td align="center"><?php print $row['vic2_state']; ?></td> </tr> Now it displays both rows, even if its empty. It doesn't matter if the victim was listed originally as vic1 or vic2, i just want to know if they are a victim. I hope this makes sense. I can't get it to display the way I want, line-by-line, irregardless of whether you are vic1 or vic2.

  • Generate form based on selection

    - by Jay
    I'm looking to build a web application that allows a person to select a plan and fill out an application for that plan. There are multiple plans and each plan generates a different application. Some of the questions are identical such as fields related to personal information. I'm thinking of using ASP.NET MVC to build this web application. When generating the multi page application would it be best to Create partial views (sections of applications) and combine them when generating the form. OR Build some type of dynamic form generator

  • Character problem at displaying the result of a query

    - by rahmivolkan
    I am not good at jsp but I wondered what can cause such a problem when every other strings are displayed well: a JSP file queries information of people by their name at Contact (MS Exchange). the query returns the full info of the person; and the first, last names are printed. Last names with apostrophes (Ex: O'reilly) aren't displayed at all. what can be possible solutions? Thanks in advance P.S. I know the way of asking is not suitable but, I need information from people who had such a problem before.

  • download authentication?

    - by Sahat
    Hi I am sorry if this question has been asked before but I am looking for some sort of download authentication. In other words if I am going to give the user a link to a file, I want to make sure only that person will get it, and get it only once! Is there a simple solution without setting up the whole database. Even better if it's possible to have an ecrypted web link that will let you download a file from my FTP server just once, after that the link becomes invalid. Thanks.

  • How can I get Facebook Profile image from email?

    - by Forbini
    There's an outlook plugin called Xobni that has a really cool feature, if a contact has an email address, it will fetch that contact's profile picture and display it. Their FAQ states the following: Xobni sends an encrypted email address to Facebook to retrieve the Facebook profile for the person who is currently being viewed in the Xobni sidebar. Your own Facebook profile is never altered by Xobni, and all Facebook privacy settings are strictly followed when viewing other profiles. I'd like to duplicate this functionality. However, I can't figure out which API call they're using. I'm assuming when they say "encrypted email address" that's laymen's terms for the email hash. Once a username is derived, the graph api looks ideal for actually fetching the image, but I'm having trouble going from email hash to profile ID.

  • ruby on rails w/ SQLServer

    - by jaydel
    I've heard from some people that RoR doesn't marry cleanly with SQLServer. We have a series of historical, standardization to use SQLServer but if we can push back with valid reasons we can move to another db. One person on the team wants MySql and another wants Postgres, etc. I'm trying to stay out of the religious wars and really understand what the pain point is with SQLServer. We're running the app server on a linux box, and the database will be on a windows box and the SQLServer that we're supposed to standardize on is 2008, if those details help any... thanks in advance!

  • Difference between :: and -> in PHP

    - by vrode
    I always see people in serious projects use :: everywhere, and - only occasionally in local environment. I only use - myself and never end up in situations when I need a static value outside of a class. Am I a bad person? As I understand, the only situation when -> won't work is when I try following: class StaticDemo { private static $static } $staticDemo = new StaticDemo( ); $staticDemo->static; // wrong $staticDemo::static; // right But am I missing out on some programming correctness when I don't call simple public methods by :: ? Or is it just so that I can call a method without creating an instance?

  • Value of Step-by-Step Asserts in Unit Tests

    - by Eric J.
    When writing unit tests, there are cases where one can create an Assert for each condition that could fail or an Assert that would catch all such conditions. C# Example: Dictionary<string, string> dict = LoadDictionary(); // Optional Asserts: Assert.IsNotNull(dict); Assert.IsTrue(dict.Count > 0); Assert.IsTrue(dict.ContainsKey("ExpectedKey")); // Condition actually interested in testing: Assert.IsTrue(dict["ExpectedKey"] == "ExpectedValue"); Is there value to a large, multi-person project in this kind of situation to add the "Optional Asserts"? There's more work involved (if you have lots of unit tests) but it will be more immediately clear where the problem lies. I'm using VS 2010 and the integrated testing tools but intend the question to be generic.

  • What is the best way for the application to refer to the user?

    - by user292450
    Forgive my noobishness, first time poster on stackoverflow! I can have the application read: "view your messages" "view my messages" "edit your profile" "edit my profile" etc. and others like that. Is one of these more correct then the other? I suppose that I could use neither and just leave it without any pronoun, but I would rather not. The person grading is a real stickler for "grammar" in code. Any input would be appreciated!

  • How Can I Run a Regex that Tests Text for Characters in a Particular Alphabet or Script?

    - by Eli
    I'd like to make a regex in Perl that will test a string for a characters in a particular string. This would be something like: $text =~ .*P{'Chinese'}.* Is there a simple way of doing this, for English it's pretty easy by just testing for [a-zA-Z], but for a script like Chinese, or one of the Japanese scripts, I can't figure out any way of doing this short of writing out every character explicitly, which would make for some very ugly code. Ideas? I can't be the first/only person that's wanted to do this.

  • What key concepts and nuances in C++ you know?

    - by Narek
    What kind of key points and concepts should a person know from C++ (and from programming in general) to be considered that he/she possesses C++ (and programming, in general) skills good. e.g. //Even if sizeof(T) may not be equal to 1, this code steps over array elements T v[]; for(T *p = v ; *p != 0 ; p++) cout<<*p<<endl; P.S. I hope by exchanging this info we will help each other to know C++ and programing thechnics better by doing explicit our notion that we got from practice.

  • How do I create if statements in php to perform a specific action depending on what form has string in it

    - by user1637284
    Im trying to create a grid on my page in each cell there will be a simple one line form. If a person enters data into lets say FieldA I would like the php to perform actionA but if the data was entered in FieldF I would like actionF performed. Is this possible without having to create a php for each cell and upload all those php files? Or is there a way to perform the GET method in each form to append the data to the end of the action url without the field name showing (ie sample.com/somestuff/fieldA instead of sample.com/somestuff/fieldname=fieldA) thus not needing php at all?

  • How do I push a new controller via UIButton, nested in a UIScrollView?

    - by jimijon
    Hello - I have my views that are part of a tabBar. Each view has a navigationController. In one of my views I have an embeded xib component. This is a scrolling view with UIButtons inside it. I want to slide in another view, inside the navigationController when a person taps the button. I can get the taps, etc. BUT, I can't figure out how to find the controlling navigationController of that page to push the new view into. Nothing seems to work that I have tried. IS this possible? Thanks

  • Requiring clients to solve computational puzzles...

    - by acidzombie24
    Not that I need it, but it was interesting to hear someone speak about their server and protecting it from DOS attack by having a puzzle that the client must solve before the server will do anything (it doesnt do allocations or make a session unless solved). The person also said puzzles can be made to take a quick amount of time or long. And they are easy to check for correct solutions but difficult to solve. What are these puzzles? I never heard of one. Can someone give an example (or a link)?

  • C# Generics Multiple Inheritance Problem

    - by Ciemnl
    Can any one help me with this syntax issue with C#? I have no idea how to do it. class SomeClass<T> : SomeOtherClass<T> where T : ISomeInterface , IAnotherInterface { ... } I want SomeClass to inherit from SomeOtherClass and IAnotherInterface and for T to inherit ISomeInterface only It seems the problem is that the where keyword screws everything up so that the compiler thinks both ISomeInterface and IAnotherInterface should both be inherited by T. This problem is very annoying and I think the solution is some kind of parenthesis but I have tried and failed finding one that works. Also, switching around the order of the two items inherited from SomeClass does not work because the class inherited always has to come before any interfaces. I couldn't find any solutions on the MSDN C# generics pages and I can't beleive I'm the first person to have this problem. Thanks, any help is much appreciated!

  • Merge Twitter Outh and Facebook Connect Friends

    - by G Ullman
    Basically what I want to do is download all a users facebook and twitter friends and somehow find a way to figure out which entries represent the same person. I know it's possible because a lot of social search sites like spokeo achieve what I want and more, so does anyone know how they go about doing it or the best way to go about it? I have a basic idea of the facebook and twitter api calls I need to be making however feel free to add any advice or warnings there as well. I know facebook hashes the emails which seems like it could pose a problem. Any help is greatly appreciated.
