Hi all!
I would like to know: when programming in C using a socket (AF_UNIX) is there any limit (in bytes) when sending or receiving to or from a socket?
Thank you!

I'm currently investigating what the runtime of different programming languages looks like behind the scenes. For a compiled language like C, people usually give the explanation of "Code is compiled to assembly which is assembled and linked into a binary executable. The executable is then loaded into memory and the CPU interprets it." My question is how does the CPU know where to look for the next instruction to execute? Is it a memory address stored in one of the registers?
Pretty basic programming question, I know PHP have a function for it, but does the iPhone OS have one?
I want to check if the current indexPath is a value in an array.
PHP Example:
<?php
$indexPath = 3;
$array = array("0", "1", "2", "3", "4");
if (in_array($indexPath, $array)) {
// Do something
}
?>
Does anybody know how to do the same thing inthe iPhone OS?
hello.
In meta-programming number of classes grows quite fast.
Is maximum number of classes modern compiler allows, for example g++, something to be concerned about?
Thank you
I am new to C++ programming, but I have experience in Java. I need guidance on how to pass objects to functions in C++.
Do I need to pass pointers, references, or non-pointer and non-reference values? I remember in Java there are no such issues since we pass just the variable that holds reference to the objects.
It would be great if you could also explain where to use each of those options.
I have a string (R(46 - 9900)) AND ( NOT (R(48 - 9900))) where R denotes Range . If you evaluate the expression it results in R(46-47) , considering the logical operators (AND,NOT).
I have a requirement where I need to parse such a string and evaluate it to a correct result . I have to use C++ as a programming tool to achieve this result .
Can anyone suggest a few guide lines as to how do I proceed on this ?
I want a simple timeline component (like in video editing software) for a clojure/seesaw app and I am wondering if it is a good approach to implement this directly with clojure and seesaw or if I should write it in java and make my clojure wrapper around it.
Or more generally: is a functional programming language optimal for writing UI widgets? I cannot imagine doing that without a lot of state involved. And wasn't OO invented for UI-development in the first place?
I have a basic html form that adds some data to the page using PHP. I want to make this form field a "Price" field. My html is:
<input class="bids" name="comment" id="comment" tabindex="4" />
How can I fix this field so that users can't enter random letters, dollar signs, dashes, or other weird formats. I want the output to be whole dollars. Sorry I'm a complete programming moron. :)

Hi,
I am basically working on unix and c programming.
i want to start learning Pro*c on unix.
Is there any good online tutorial which will help me start writing simple programs in pro*c and compiling those Pro*c files.?
Thanks in advance for your help.
I would like to add a favorites tab to my iphone app that i am developing. I am using core data to populate a UITableView and would like in the detailed view to be able to add the selected item to the users favorites.
Would i go about this by adding the selected item to a new array?
I am very new to xcode and iphone programming so as much help and code would be gratefully received.
I'm trying to use Eclipse + PyDev for studying OpenGL programming but when I type
from OpenGL.GL import *
from OpenGL.GLUT import *
IDE becomes extremely slow!
Ok. It isn't a smart idea import to much useless things but it's so useful for learning a new library!
Any help?
PS: I use Ubuntu with Eclipse Galileo.
PHP was the undisputed king of easy webapp development, until Ruby on Rails, Django, and other dynamic programming frameworks appeared. What are, in your opinion, PHP's strengths against the newcomers?
I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together.
What's a good starting point to understanding what looks like the only rocket-science programming language in the world?
Links to articles, books or anything else that could help me get my grounding would be appreciated.
I'm currently developing a small Database Management System for a local company. How would you go about explaining how the system you have designed to a client? If they are non-technical and have no understanding of programming, how would you go about showing what the system will do and how it will do it? I guess some sort of visual representation of the system but this seems very patronising to me.
Hi,
We have request from our clients to provide a POS terminal version of our web-based software. They want to be able to enter record to their database from POS terminal (via web service) instead of using PC browser. I am the one to develop this application, as I am the lead developer of the main application. I haven't done any Windows embedded programming or .net compact edition before and would appreciate link to good tutorial or info on how to start developing for Windows CE 6.0 enabled POS terminal or device.
Thanks
I'm rather new with the whole OSX programming, I wanted to stick a WebView into an empty app. Apparently it isn't as simple as sticking a WebView on a window in interface builder and creating an outlet.
IBOutlet WebView *webView;
It gives me a
expected specifier-qualifier-list before 'WebView'
and when I don't use an outlet, it terminates due to uncaught exception. I'm not too sure what these error messages mean.
Seems it isn't that simple!
how powerful is Bluetooth programming on Android? is it possible to add new protocols and encryption techniques? or even change in the current protocols? does it support bluetooth 2.1+EDR?
I'm on my way to programming a database application and in our course we are told to implement a library of elements using one of the Java Collections. Each of the elements has a unique ID with which it's supposed to be addressed. Now I am wondering how this can be done.
I though about using a ListArray but this won't work because the only way of addressing List elements is through the index which you can't control.
Do you have some advice for me?
This is not closely related to programming stuff, so I marked as community wiki.
I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen.
Are there any apps that does this, or this is possible by the USB cable?
I'm a reasonably skilled programmer, and I'm interested in branching out into some new languages -- python, specifically -- but frankly I do NOT want to go through a tutorial that assumes I know nothing about programming. I want a tutorial -- again, preferably for python -- that assumes I'm just unfamiliar with the language itself and describes the ways I can use the language to solve problems.
Does such a beast exist? I mean, other than the Python wiki?
I need to teach myself Winforms and user interface programming and want a decent book that will go thoroughly into the ins and outs of how to accomplish things.
Can anyone suggest a good book?
I know C# pretty well and have messed about with Winforms in the designer before.
Thank you
In win32 programming in C:
Whats the best way to execute a win32 console program within another win32 program, and have the program that started the execution capture the output? At the moment I made the program redirect output to a file, but I am sure I must be able to open some sort of pipe?
I develop my app in linux for both unix and win32(cross compile at each build) plataforms, so a ready to use function would be nice :). I'm using glib that has the 'gchar* g_get_current_dir(void)' function and it returns the current directory, but what I really need is the executable's dir. I'm inexperienced in C programming so any sugestions are welcome.
