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?
Hi,
Is there any way to change backlight turn off TIME using programming(Preferred c# or vb.net other c++ can be used too)? I guess, may be it is changed using registry info or API.
Manually, it is done by:
Setting Backlight (Battery Power and External Power)
Thank you
So, I have noticed that starting an HttpListener is considered impolite according to Win 7. I cannot do so without administrative rights without adding myself to some URL reservation list. In theory, this is alright, but I'd like to make my program as little invasive as possible.
My main other alternative is something like the c++ Network Library, which utilizes boost. This is probably not as simple as a HttpListener though. Will this circumvent the admin rights requirement for listening to some HTTP url?
How does windows handle http listening? Right now I'm just listening to http://+:xxxx/url, I guess it's fully possible to just create a Socket listening at port xxxx and provide my own/third party http implementation?
I've got a real interesting situation. I have an existing web app that runs on a number of desktops fine. On a few desktops I see the following behavior:
Upon clicking a link that opens up a new window (to another URL in the same domain) the IE window freezes and IE needs to be killed.
This happens on IE 6 & 7.
When using Fiddler I see NO traffic when clicking the link.
When using IE HttpAnalyzer I see a request register but no response.
If I change the MaxConnectionsPerServer registry setting to a higher value, e.g. 10 the problem goes away.
Looking at netstat I dont see any abnormal connections.
So I'm totally confused, the issue seems to be on the client side and seems to be related to IE not being able to make an additional socket connection to the server, but netstat doesn't show that.
Ideas?
Hi. One of my friends has contacted a company that is looking for good, linux network programmers in C, requiring a good background of the linux kernel and low-level network programming. The starting payment would be $70 per hour - I am still at college and honestly i don't know if that's a good salary for such a work as linux network engineer, so i am asking here if $70/h is good enough or not ?
Thanks.
I have a program I want to profile with gprof. The problem (seemingly) is that it uses sockets. So I get things like this:
::select(): Interrupted system call
I hit this problem a while back, gave up, and moved on. But I would really like to be able to profile my code, using gprof if possible. What can I do? Is there a gprof option I'm missing? A socket option? Is gprof totally useless in the presence of these types of system calls? If so, is there a viable alternative?
EDIT: Platform:
Linux 2.6 (x64)
GCC 4.4.1
gprof 2.19
I'm a blind student currently in a system admin/shell programming class. Although ssh works fine for executing commands like ls, pwd, etc editors do not work well with my screen reader and an ssh session. I was wondering if it is possible to mount a Linux folder over ssh so it appears as a windows drive? This way I could edit any files I needed to with accessible software and not have to constantly use SCP to send files back and fourth.
Hopefully this question is allowed over here. It does not really have to do with programming per se but with the costs associated with it.
My question is:
"How much does sending/receiving XMPP
messages cost".
I can find all the information about email etc. But I could not find information about costs sending/receiving XMPP messages.
I don't want to take the time to learn Obj-C. I've spent 7+ years doing web application programming. Shouldn't there be a way to use the WebView and just write the whole app in javascript, pulling the files right from the resources of the project?
Though it's on the edge of programming questions, I think this is still relevant here, as only those of us actually doing the coding for a site would be considering this.
I've been reading more about keyword placement, and it seems to me like a good place to do keyword placement would be in the class and id names chosen for the elements they are representing. I'm not talking about any kind of black-hat keyword stuffing thing but real legitimate use of descriptive keywords for elements.
Is this something that is actively done for SEO?
Hi there.
Once I read an MSDN article that encouraged the following programming paradigm:
public class MyClass
{
public void Method1()
{
NewCustomException();
}
public void Method2()
{
NewCustomException();
}
void NewCustomException()
{
throw new CustomException("Exception message");
}
}
Do you think this paradigm makes sense? Wouldn't it be enough to store the exception message in a static const field and then pass it to the exception's constructor, instead of encapsulating the whole exception throw?
For many questions, especially for C-related ones, the answer seems to be found in "the standard". However, where do we find that - online?
Googling can sometimes feel futile, again especially for the C standards, since they are drowned in the flood of discussions on programming forums ;)
To get this started, since these are the ones I am searching for right now, where are there good online resources for:
C89
C99
C++03
Is there high-level language out there for describing algorithms, that's geared towards specification, rather than implementation?
The idea would be to have a machine-readable archive of standard algorithms, with machine-readable annotations on trade-offs, and variants.
I'm thinking of something like CycL / OpenCyC, but for algorithms and programming patterns.
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 have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?
When programming, I would like to split one large file(which contains main function) to many small files, so there is one common case: functions in small files can modify the var from main file, so i think extern is very useful!
for instance:
in main.c
extern int i = 100;
in small.c
extern int i;
fprintf(stdout, "var from main file: %d\n", i);
I just want to know is my understanding right?
Hey guys
I'm very new to the whole programming - so far I only have experience with building websites, database etc.
I currently have a website where users can share their online purchases.
I want to build a widget that other websites can integrate on their site. Users should be able to insert their purchases directly through this widget without having to come to my website.
Thats the idea but I have no idea how to go about it - can anyone point me in the right direction.
Thanks
Ever since I started programming this has been something I have been curious about. But seems too complicated for me to even attempt.
I'd love to see a solution.
1, 2, 3, 4, 5 // returns 6 (n + 1)
10, 20, 30, 40, 50 //returns 60 (n + 10)
10, 17, 31, 59, 115 //returns 227 ((n * 2) - 3)
Some programming environments like C++ builder have timer components with a callback function which executes in the same execution contexts as where the timer object is created.
I was wondering how to do something similar in plain c++ with threading.
Or are there any other ways to have a callback which is periodically called to perform some task and runs in the same execution context as the calling thread?
I'm looking for a complete list of security guidelines for programming and deploying PHP web sites and applications on an Apache (Linux) server. Basically, a "security check list" to run through before finishing a project. I.e.,
Cross Site Scripting
Cross Site Request Forgery
Sanitize form data that goes into database
Disable register globals and error reporting in custom php.ini
Upload files below web root
...(the list goes on)
I did some searching on the internet and in this forum, but couldn't find a comprehensive, succinct, and complete list of guidelines.
Thanks in advance.
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?
What is the most painful programming mistake you have done and what lesson you have learn after?
I guess mine was making a release to production on the development code which was not tested yet.
The lesson-learned:
Delete any projects that can trigger a
release on the live application from
CCTray. I only add them when a release
to production is necessary since then.
And once I am done, I delete them from
my project lists.
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?
Dear All,
I M building a application in which i want to download large files on handset
(mobile),but if size of file is large i m getting exception socket exception-broken pipe .
inputStream = new FileInputStream(path);
byte[] buffer = new byte[1024];
int bytesRead = 0;
do
{
bytesRead = inputStream.read(buffer, offset, buffer.length);
resp.getOutputStream().write(buffer, 0, bytesRead);
}
while (bytesRead == buffer.length);
resp.getOutputStream().flush();
}
I have installed xcode 3.2 with iphone SDK. (without Mac OS 10.4 SDK). WHen i create new project i only got these options for Mac OS
-- Application
-- Framework and Library
-- Application plugin
-- System plugin
--Other
But a book named: Programming Object C 2.0. From which i am learning object C. Its showing XCode with these templates for Mac OS
--Application
--Audio Units
--Automater actions
--Bundles
--Command Line Utility
--dynamic library
--Framework
--Java
--Kernal Extensions
--Standard Apple plugin
--Static Library
