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 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. :)

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.
Is it practically possible to create a triangle of stars like this as below in SQL.I know that this could be done easily in any other programming language like C,C++,Java but want to know whether it is really possible with just SQL or PL/SQL.I tried working on it with dual table in Oracle but couldn't get through it.

Can someone please shed somelight if anyone knows about it.
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!
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?
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.
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 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.
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 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
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 some help!, i am planning to develop such LBS Mobile Application which find nearest things based on gps data from mobile.
1.what are the best free and (preferably) open source technologies for development?.
2.What programming language to use for development of such application?.
3.what are the points to be considered?
I need the general overview of the requirements for planning, I was interested in having a general understanding of the data, tools, and frameworks required to accomplish the job.
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?
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?
If you were a programming teacher and you had to choose one sorting algorithm to teach your students which one would it be? I am asking for only one because I just want to introduce the concept of sorting. Should it be the bubble sort or the selection sort? I have noticed that these two are taught most often. Is there another type of sort that will explain sorting in an easier to understand way?
Hi,
I am creating a sites by java programming using google sites API developer guide. I had easily created different type of pages as parent page and sub pages also. my problem is,I am not able to create a web page as parent page and file cabinet, announcement, list page as sub page. That's parent page and sub page is created as same not as different page. please tell me a solution.
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 recently started working on my first SharePoint (2007) project (C#), so I was wondering if anyone can point me to some good resources that will get me up and running with SharePoint programming basics quickly. I'd like to have a deeper understanding of the various terms I'm hearing such as Features, Lists, wsp, etc.
does anyone know of a visual programming tool that could be adapted for children (kids age 7-12) so that they can generate c programs to control device?
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.
We want to persist some user settings int he GUI part of our code. I used to do Win32 programming exclusively and the typical way this was done was with registry settings.
I assume that this should be done with configuration files, but was wondering if there was a library or cross platform wrapper that made key/value pair persistence very easy.
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?
