• How to step inside NSManagedObject; access individual attributes.

  - by user300972

  NSManagedObject *entryObj = [self.fetchedResultsController objectAtIndexPath:indexPath]; entryObj consists of four String attributes. If I NSLog entryObj, I get the information I want. I cannot figure out how to access each of these properties individually. I read a similar post where the solution was to call "entity." I cannot figure out how to use "entity" to access a specific attribute. Any ideas? References? Tutorials? Thanks in advance.

• How to return result set based on other rows

  - by understack

  I've 2 tables - packages and items. Items table contains all items belonging to the packages along with location information. Like this: Packages table id, name, type(enum{general,special}) 1, name1, general 2, name2, special Items table id, package_id, location 1, 1, America 2, 1, Africa 3, 1, Europe 4, 2, Europe Question: I want to find all 'special' packages belonging to a location and if no special package is found then it should return 'general' packages belonging to same location. So, for 'Europe' : package 2 should be returned since it is special package (Though package 1 also belongs to Europe but not required since its a general package) for 'America' : package 1 should be returned since there are no special packages

• How to split row into multiple rows from the MySQL?

  - by user2818537

  I have a MySQL data table, in which I have more than 2 columns. First column has a unique value clinical trial value whereas second column has disease information. There are, in most of the cases, more than 2 disease names in one cell for a single id. I want to spilt those rows which cell contains two or more than two diseases. There is a pattern for searching also, i.e. small character is immediately followed by capital character., e.g. MalariaDengueTuberculosis like this. Suppose for these three diseases there is unique id, it should show like the following: NCT-ID disease 4534343654 Maleria 4534343654 Dengue 4534343654 Tubercoulsosis

• How many SQL queries per HTTP request is optimal?

  - by Chris Kooken

  I know the answer to this question for the most part is "It Depends", however I wanted to see if anyone had some pointers. We execute queries each request in ASP.NET MVC. Each request we need to get user rights information, and Various data for the Views that we are displaying. How many is too much, I know I should be conscious to the number of queries i am executing. I would assume if they are small queries and optimized out, half-a-dozen should be okay? Am I right? What do you think?

• PHP from database and query

  - by Kyle R

  I have a table: id, affiliate Each time somebody clicks a link, a new row is inserted, ID being the ID of the page, and affiliate being the ID of the affiliate. For example: Page ID: 9 Affiliate ID: 1 Page ID: 9 Affiliate ID: 2 Page ID: 9 Affiliate ID: 3 I only have 3 affiliates. I want to select this information, and group them by affiliate, for the ID. I have tried this query: SELECT COUNT(*) FROM table WHERE id = '9' GROUP BY affiliate It works fine when I do it in php my admin, how do I get the info in PHP? I have tried: $q = mysql_query("SELECT COUNT(*) FROM table WHERE id = '" . $id . "' GROUP BY affiliate"); $r = mysql_fetch_array($q); When trying to print the data onto the page, I am only getting one result. Do I need to use a foreach/while loop to get all 3? How would I go about doing this? Thank you!

• MySQL text field issues

  - by chenger

  This is quite a noobish question, I have searched for a few hours now and I know this has to be simple. I am using XAMPP and I am trying to learn some more about using PHP and mySQL together. When I create the DB and the table for information to store, I tried insert info to the table and it stores it as a .dat file rather than text. I know this has to be with how I am setting up the table or the DB but I have gone through things and I think I am just skipping over something. * Apache/2.2.12 (Win32) DAV/2 mod_ssl/2.2.12 OpenSSL/0.9.8k mod_autoindex_color PHP/5.3.0 mod_perl/2.0.4 Perl/v5.10.0 * MySQL client version: 5.1.37 * PHP extension: mysqli that is the phpmyadmin info.

• Select multiple unique lines in MySQL

  - by MartinW

  Hi, I've got a table with the following columns: ID, sysid, x, y, z, timereceived ID is a unique number for each row. sysid is an ID number for a specific device (about 100 different of these) x, y and z is data received from the device. (totally random numbers) timereceived is a timestamp for when the data was received. I need a SQL query to show me the last inserted row for device a, device b, device c and so on. I've been playing around with a lot of different Select statements, but never got anything that works. I manage to get unique rows by using group by, but the rest of the information is random (or at least it feels very random). Anyone able to help me? There could be hundreds of thousands records in this table.

• read variables from file

  - by TonyVipros

  Hi, I'm trying to write a shell script to backup websites, I've got it to go through each directory in vhosts and create a new directory vhosts/{siteurl}/private/backups/ and gzip up the site into there. However, I also want it to read a file from private that will contain database name, user and password. So I can then use these to perform a mysqldump to private/backups/. The problem is that I've never written a shell script before so I've go no idea how to read variable data into my script, or how I should format the file to be read. Hope that's enough information.

• Is there a circular hash function?

  - by Phil H

  Thinking about this question on testing string rotation, I wondered: Is there was such thing as a circular/cyclic hash function? E.g. h(abcdef) = h(bcdefa) = h(cdefab) etc Uses for this include scalable algorithms which can check n strings against each other to see where some are rotations of others. I suppose the essence of the hash is to extract information which is order-specific but not position-specific. Maybe something that finds a deterministic 'first position', rotates to it and hashes the result? It all seems plausible, but slightly beyond my grasp at the moment; it must be out there already...

• Why doesn't this require_once statement find the file? (PHP)

  - by ggfan

  I not sure what's going on..maybe I missed something simple. In my connectvars.php file, I connect to the database using the variables in my config.php folder. Here's the hierarchy: admin(folder) config.php includes(folder) connectvars.php I want to get information from config.php to use in connectvars.php, so I use: require_once("../admin/config.php"); But everytime I do this I get Warning: require_once(../admin/config.php) [function.require-once]: failed to open stream: No such file or directory in /home/a8879415/public_html/includes/connectvars.php on line 2 BUT when I type: require_once("admin/config.php");, it works. I thought I had to go up a level, then go down to admin, then get config.php. So how come I just need to go into the admin folder then get config.php?

• Help with getting data from resized image.

  - by nick

  I'm using an ASP.NET file upload control and then resizing an image and storing the new image in a new Bitmap. Here is the code I have so far: protected void ResizeImage() { Bitmap originalBMP = new Bitmap(FileUpload1.FileContent); //Calculate new image dimensions int origWidth = originalBMP.Width; int origHeight = originalBMP.Height; int sngRatio = origWidth / origHeight; int newWidth = 100; int newHeight = newWidth / sngRatio; Bitmap newBMP = new Bitmap(originalBMP, newWidth, newHeight); } I'm uploading directly to Amazon S3 and I need to pass some data to its upload method. How do I get the following information from my new bitmap that I have been using with the fileupload?: FileUpload1.FileBytes FileUpload1.FileBytes.Length Do I need to save my new bitmap to a stream so I can get an array of bytes?

• Create proxy to Java app so it can work on the iPhone? [closed]

  - by Kovu

  okay guys, these are the facts: I have a java chat. I can NOT have any develop-revelant information. So this all is static. It's not my chat. So fact 2: IPad does not have Java and it will not have it in future. So now, the very hard task: bring this both together. My idea: Develope a proxy server for this. 1) The data from the IPad will send to a server. 2) the server recieve data and call the JRE and the complete chat-client 3) The server gets the "chat" himself and send it back to the Ipad Is that and possible idea or bad? Did I oversee something? Anyone have a idea where to start?

• What size should the background image in an MSI be?

  - by r_

  I am trying to create a Windows Installer package using Wix. I'm getting a lot of conflicting information about what size my custom background should be--the Wix documentation suggests a size of 500 x 314 pixels, but this leads to slight image distortion in the installer. I believe that I may be indirectly using the SplashBitmap property in Windows Installer, whose documentation suggests 480 x 320 is the correct size. When I try to use this image size, I also get artefacts in the image. Could anyone tell me what the correct size should be?

• How can I write my code to attempt a database action but continue executing code on failure?

  - by Chris

  Simple question I guess, I want to use PHP to write an update to an existing row in my database, if it doesn't happen I want to log the failure but continue executing the code. While it would be nice to have records of failures to track down issues, that the update failed isn't that important to my user, nor will it affect the running of any other code; the query is simply for a 'cosmetic' but entirely unnecessary piece of information. My database class's query function is set to die on failure, could I modify that or is there another way of doing it without altering my standard query code?

• Advanced Registry Monitoring

  - by RyanTimmons91

  I'm attempting to create a small utility to watch for the creation (or modification) of a specific registry key, and to kill the process responsible for causing that registry modification. I have had success in watching the changes to the registry via a class called 'RegistryMonitor', however it does not give you any information on what process initiated the registry call, through some googling I found that a library called 'EasyHook' should be able to do what I want, but all the documentation states that its designed for a per-application hook. The program itself is a temporary security patch, until our vendors come out with an official security update. As best I can tell there isn't a way to do exactly what I want to accomplish from C#, which is the only language I can comfortable write, test and execute software in. Any help on this would be appreciated I'm considering watching the registry changes via the program I already have, then if the change is discovered (the pc is already infected) running RKill and locking down the PC to prevent the issue from getting any worse

• Django: Is it possible to attach media files (css, javascript etc) to a View-class?

  - by mrmclovin

  I can't fins any information on how to define css or javascript files in a view like: class MyView(View): .... class Media: css = { 'all' : 'mystyle.css' } If you have a form you can do like: class MyForm(ModelForm): .... class Media: css = { 'all' : 'mystyle.css' } And then in the template you can print the files like; {{ form.media.css }} I like that Syntax very much and I like to keep the View-specific css files in the app-directory.

• Form Login Error

  - by ilp

  I'm having issues with a login form for my website. At the top of the login.php form I have this <?php if (isset($_SESSION['username'])){ header("Location: http://myurl/"); die;}?> <?php require 'includes/dbconnect.php' ; ?> <?php require 'includes/header.php'; ?> and when login is successful I redirect them to header('Location: http://myrul/'); Header.php has <?php session_start(); ?> at the top.

• HWID locking a PHP page?

  - by Rob

  Currently I sell a program, that accesses my webpage. The program is HWID (Hard Ware ID) locked, and the only reason I use the program to access the webpage instead of direct access via a webbrowser, is so that I can use HWID authentication. However, I've just been told I can code a script to get computer information, such as hardware ID etc. Is this actually possible completely server-side? If so, can I do it with PHP? If not, what language would this be, and what functions would I have to look into for this?

• Updating multiple rows with an array

  - by Copephobia

  I have a table that holds user information. One of the columns holds the position of the user in the game they are in. When a game is being created, I need to update the positions of the users of each team. Here is an example: Game id : 7 Team 1 users : 1,2 Team 2 users : 3,4 team1_position : array(1,2) team2_position : array(13,14) What I want to do is update the user table using the array of positions in the SET area. My goal is to be able to update the users without the need for their id (I have different size game boards, so I have multiple position arrays for each board size) How can I do something like this: UPDATE user SET position='(team1_position)' WHERE game = '7' AND team = '1' I feel like it would be a waste of resources to select all the id's of each team and update them separately.

• Recursive solution to finding patterns

  - by user2997162

  I was solving a problem on recursion which is to count the total number of consecutive 8's in a number. For example: input: 8801 output: 2 input: 801 output: 0 input: 888 output: 3 input: 88088018 output:4 I am unable to figure out the logic of passing the information to the next recursive call about whether the previous digit was an 8. I do not want the code but I need help with the logic. For an iterative solution, I could have used a flag variable, but in recursion how do I do the work which flag variable does in an iterative solution. Also, it is not a part of any assignment. This just came to my mind because I am trying to practice coding using recursion.

Are there part time jobs available for someone like me and are my skill set enough to get me a job? I understand this topic may not be ideal here but this is the only place I know can provide me answers. Thank you!
