• What is "with" used for in PHP?

  - by Jason

  I have come across this line in the eloquent ORM library: return with(new static)->newQuery(); I've never seen "with" used before, and cannot find it in the PHP documentation. I'm guessing "with" is a stop-word in most searches, so I am not even getting close. Never having encountered "with" in many years of programming PHP, I feel like I'm missing out. What does it do? I did come across one passing comment regarding the ORM, that mentioned "with" is no longer needed in PHP-5.4, but that was as much as was said.

• How can I make a boring project (another WordPress site) interesting?

  - by Christopher Altman

  WordPress is my example, but the question can be generalized to any technology that is not particularly interesting. To me, WordPress takes away the intellectually gratifying pieces of coding. I would rather write a new version of WordPress than write a WordPress theme and glue together some plugins. I am using WP because my company dictates the platform for some of our clients (I do not disagree with the choice from a business perspective, WP is quick and cheap to implement). My question is, how can I make my next WordPress project interesting? I want to advance my understanding of the fundamentals of programming (aka data structures, algorithms, and caching) but do not see how I can achieve this when coding another WP site. I have a fairly tight understanding of front-end technologies and believe I have made WP do things it was never intended to do. Examples are here and here. Solving front-end related problems is not as interesting as coding a full stack application. Any advice will help.

• How can I test if an input field contains foreign characters?

  - by zeckdude

  I have an input field in a form. Upon pushing submit, I want to validate to make sure the user entered non-latin characters only, so any foreign language characters, like Chinese among many others. Or at the very least test to make sure it does not contain any latin characters. Could I use a regular expression for this? What would be the best approach for this? I am validating in both javaScript and in PHP. What solutions can I use to check for foreign characters in the input field in both programming languages?

• Mercurial: Recommended way of sending a whole repository to someone

  - by Svish

  I have done some programming and I have used Mercurial for source control. I now need to send all of my code to someone else (because they are going to take over). Since all copies of a mercurial repository is a full and real repository my first thought is to first do a clone of my repository without an update and then zipping and emailing that clone. Is this a good way, or is there a better way? For example when using the TortoiseHg Repository Explorer I can right-click on a changeset and under Export there are various options that looks like they could be doing something interesting, but I don't quite understand them or know which one to use.

• [ADVICE] .NET Desktop Application - Client Server C#, SQL

  - by Rillanon

  Hi guys, Recently I've being given a chance to develop a PMS (Practice Management System) software for a small physiotherapy clinic. I'm a computer science student and my course is predominately told on Linux. However, my client runs all their computers on vista or Windows 7. My ideas are to develop the client front end in Visual C# and access a central postgresql server. I'm a beginner in Windows Programming so I'm after advice on best practice on implement user rights and access levels in C# (WPF or Windows FORM). I've had a look into Credential class in Visual C# and access control list but please share your thoughts. I'm probably way over my head on this but this is my first commercial project so I'm keen to test the waters. Cheers Ian

• WIN32 visual c++

  - by mrbuxley

  I would like to write a simple program in c++. After the program is done i would like to get my answers in form of a graph or picture that would give some certain information if i click on a certain area. i have only written console apllications in c++ before and don't really have a clue where to start with the graphic part of it all. Can I write the first part of the program in console mode and some how run it under the WIN32 later? for ex what will happen to the cout<<"foo"; commands? Is there a simpler approach to do some very basic graphic programming.

• download a complete folder

  - by Christian

  Hi, in my app I use several png-graphics. For the present version they are installed with the app in the folder "graphic". I made while programming. Now I need some more png-graphics and I don't want to make each time an app-update. How can I manage it, that the app is downloading the png-files from my webserver without knowing the name. I am looking for something which compares the files on the webserver with the files on the iPhone and if there is a new (or newer) file download it. Or is it possible to make an plist-file with the graphics??

• WebGL on older Mac OS X versions (say 10.4)

  - by rotoglup

  Not really a programming related question but... I'd like very much to experiment with WebGL on my spare time. My current 'spare time' machine is a MacBook running Mac OS X Tiger (10.4.xx) and I'm unable to find a new browser supporting this OS. Firefox dropped support, Chrome too, and Safari idem. I read somewhere that this is due to a Quicktime bug that Apple won't fix. Does anyone have more information on this issue ? Does anyone have a clue or track to find a running implementation of WebGL on Mac OS X 10.4 ? Cheers,

• Many-to-Many Relationship (with properties) in Google App Engine for Java

  - by rvandervort

  I understand from the official documentation on unowned relationships that the app must use sets of Key objects on either side of the relationship. This makes perfect sense. Coming from many years of RDBM-style programming, though, I'm pretty confused about how I can model properties of that relationship itself. For example, if I have entities Category and Entry in my many-to-many relationship and would like to persist a dateAdded property, or some other data that are only relevant when both sides of the relationship are known. I suppose it would be possible to create a third class : CategoryEntry that links the two, but this seems like a kludge. What is the proposed way to model this kind of situation ?

• ValidateRect vs BeginPaint

  - by Armentage

  From the MSDN documentation: The BeginPaint function validates the entire client area. The ValidateRect function should not be called if a portion of the update region must be validated before the next WM_PAINT message is generated.1 I've been programming with Win32 API for years, and I've never thought to call the ValidateRect function. A co-worker of mine today pointed that we were missing a call to ValidateRect, which fixed a bug we were having doing some high-speed animation using GDI (I know, an oxymoron) Can someone tell me whether or not a call to ValidateRect is neccessary after a BeginPaint/EndPaint pair? I have seen no documentation at MSDN that sheds light on this, and what documentation and examples I do see that you do not need to.

• generate random characters in c

  - by Nick

  I'm new to programming in C and have been given the task of creating a 2D array that stores random letters from A-Z using the random () function. I know how to do random numbers. nextvalue = random ( ) % 10001; but am unsure on how exactly to create a random character. I know that you can use ASCII to create a random character using the range 65 - 90 in the ASCII table. Can anyone help me come up with a solution? I would greatly appreciate it.

• What is the precedence of characters when sorting in MySQL, PHP, or just in general?

  - by FireCoding

  Question: Where can I find the precedence of characters when sorting in MySQL, PHP, or just in general on Linux and Windows OS? For example, everybody knows that a comes before b when performing an ascending sort on a string in MySQL. But what about other characters? Does the dollar-sign $ come before asterisk * ? Does a space come before an exclamation-mark? etc... What dictates the sort order? Does it use underlying ascii / UTF-8 values? Is it different for different technologies? Technologies to consider: Databases - MySQL / SQL / SQLite / Oracle / etc Programming languages (for string-sorting functions) - PHP / Javascript / ASP.NET / Visual C# / Python / Ruby / Objective C OS (i.e., sorting files by filename) - Windows / Linux / MacOS / iOS / Android

• How to link .lib library in linux

  - by giga

  I'm pretty new to c programming and want to port a windows c application to linux. My code uses a .lib file va_g729.lib - is it possible to use the same library in Linux and compile it with gcc? All my .c and .h files along with the one .lib files are in the same directory. What I'm doing now is executing this command in the directory: gcc *.c -lm and I get following errors: lbcodec2.c:(.text+0xa6b): undefined reference to `va_g729a_init_encoder' lbcodec2.c:(.text+0xa83): undefined reference to `va_g729a_encoder' collect2: error: ld returned 1 exit status Is it possible to link the .lib file and compile with gcc? Thanks.

• What's some simple F# code that generates the .tail IL instruction?

  - by kld2010

  I'd like to see the .tail IL instruction, but the simple recursive functions using tail calls that I've been writing are apparently optimized into loops. I'm actually guessing on this, as I'm not entirely sure what a loop looks like in Reflector. I definitely don't see any .tail opcodes though. I have "Generate tail calls" checked in my project's properties. I've also tried both Debug and Release builds in Reflector. The code I used is from Programming F# by Chris Smith, page 190: let factorial x = // Keep track of both x and an accumulator value (acc) let rec tailRecursiveFactorial x acc = if x <= 1 then acc else tailRecursiveFactorial (x - 1) (acc * x) tailRecursiveFactorial x 1 Can anyone suggest some simple F# code which will indeed generate .tail?

• python challenge, but for C++

  - by davidthepsycho

  Does anyone know any site or book that presents problems like python challenge, but for C++? When I think python challenge, I do not mean only a set of problems to be solved with C++ (for that I could probably use the same problems of python challenge), but rather problems that will probably be best solved using C++ STL, special features of the language, etc. For example, there is one python challenge that is specifically designed to teach you how to use pickle, a serializing library for python. Until now, I only know programming contests problems, but they could also be solved with C, java or other languages.

• How to add up amount of data from an external file in C# (Stream Reader)

  - by user2985995

  I'm new to this site, and pretty new to programming, at the moment I'm trying to display a count amount for the users names on my donation list, and then I also want to have a sum to work out the total amount of money the donation list contains, If someone could help me with creating a way to add up amount of donors on the donations.txt file that would be great help, I have no idea where to start, but so far this is my coding: string sName; double dAmount; string sTotalNames; double dAmountTotal; double dAmountAverage; using (StreamReader sr = new StreamReader("Donations.txt")) { while (sr.Peek() != -1) { sName = sr.ReadLine(); Console.WriteLine(sName); dAmount = Convert.ToDouble(sr.ReadLine()); Console.WriteLine(dAmount); } Console.WriteLine("Press any key to close"); Console.ReadKey(); }

• The right way to setup VisualStudio 2010 for OpenCL

  - by LonliLokli

  what is the right way to setup VisualStuio 2010 for working with *.cl files? I have added *.cl under Tool/Text editor/File extensions and copied usertype.dat into the common7/ide folder, but VS underlines keywords like float4 or cross. Is it necessary to add some key in registry or can somebody propose a tutorial? Thanks in advance. PS i have already asked similar question old one question, but now i am looking explicit for a solution with vs2010. It is not bad, but really nerves and deflects me from programming tasks.

• C++ hook process and show status

  - by David

  Ok so I am learning C++ slowly. I am familiar with all the console syntax and everything, but now I'm moving on to windows programming. Now what im trying to do, is create a DLL that I inject into a process, so it's hooked in. All I want the C++ application to do, is have text in it, that says "Hooked" if it's successfully injected, and an error if something wrong happened. Or even if I can do it without a DLL, Just open an executable, and when the certain process I'm trying to hook is opened, the status is changed to "Hooked". Also I have a safaribooksonline.com account so if there is any good reads you would recommend, just write it down. thanks

• Artificial Intelligence - What to put in, or leave out, and what can be inferred?

  - by D Scott

  I was having a discussion with a coworker (while we were programming) about AI. We were talking about emotions/feelings and if you should choose to leave any out. I asked him, "Would you leave out racism or hate?" and if you did leave those out, what, if any, other emotions might lead to the AI learning the left out emotions or feelings. Should you PROGRAM in measures to stop the AI from learning those feelings? If you teach Love, does it need to know hurt? Or would it learn hurt? If it then knew Hurt would it connect it with Dislike, Hurt and Dislike could that then lead to some other non-programmed emotion? Such as hate? All while tele-commuting from home.

• Running Java Server Application 24/7 (NOT on local machine) ...?

  - by Steven

  I am currently experimenting with Java Socket Programming and succeeded in creating a simple application that allows me to send data back and forth between a client and a server. I don't want to power my laptop (on which the server application runs) 24/7. Therefore, of course, no computer (that runs my client application) will be able to communicate with my selfmade server application as long as my laptop is turned off. Now I'd like to know: (1) Is it possible to run the server application on a remote (physical) server, so that I don't need my laptop for that purpose? (2) If yes, do you have any suggestions where I could rent such a remote server? As I said, I'm just curious about how all that stuff works. I don't really something expensive.

• javascript code to prevent screensaver from starting

  - by gertjan

  Hi all, I am completely new to javascript programming and I have a question that I didn't manage to find an answer for anywhere. I have recently put together a simple slideshow to view the photos remotely that I host on my home computer. This by itself works fine. The problem I run into is that when I'm viewing photos I don't interact with the hardware, which after some time causes the monitor to switch off. This is particularly annoying when watching photos on my mobile phone. My question is: is there a way to prevent this from happening? I am thinking in the direction of faking a mouse or other event every time I refresh the photo, but I have no clue how to do that and if it is possible. Any help is greatly appreciated!

• working with files on "start without debugging"

  - by user1472066

  I'm programming in C, and I have the following problem: I use fopen and try to read from a csv file, that is currently storred in the folder of the exe file of the program. the program works fine in debug mode and release mode, but when I try to run the program in "start without debugging" on visual studio 2008 express edition, the program stops working and windows is showing a message: "*.exe has stopped working. a program caused the program to stop working correctly. windows will close the program and notify you if a solution is available". I've tried running the program on several computers, and it's the same. another information I can give you is that if I enter the full path of the file (C:....file.csv) - then is works just fine, without any problem. I know I didn't write any code, but I hope someone will have an idea why this can happend. thanks is advance.

• Mathematica quickie: About making cells Input cells by default.

  - by andrz

  I'm going through some lecture notes, Fundamentals of Mathematica Programming (see the .nb file there). I'd like to be able to do the exercises right there in the notebook; but for some reason I can't figure out how to make the default cell an Input cell. In other words, when I'm clicking in that notebook to create a new cell--in the exercises--the cell is by default a text cell. I'd like for it to be an Input cell so that I don't have to manually change it each time. Ideas?
