  • WCF or Sockets for Communication in a real-time environment?

    - by PieterG
    I have a scenario where I need to send a series of data across 2 clients. The data includes Serialized XML that will contain commands that the other client will need to react to. I will also need to send images across the wire as I need to provide a chat facility in the form of video/audio chat. I would like a single communication medium for both, as the number of messages/commands might be a few. WCF or Sockets?

  • Get the number of packages transmitted per connection

    - by Daniel
    How do I get the number of packages transmitted per TCP connection? I am using Java, but i know I will have to fetch the number from the underlying OS, so this quastion applies to Linux and Windows operating systems and will have different answers for each of them, I assume. I need this information to profile the network load of an application which seems to send too many small packages by flushing the socket streams too often.

  • What will be the OOP approach? (or YOUR approach?)

    - by hsmit
    I'm having difficulties with some general OOP & Java approach. There are various ways to let classes/objects communicate with each other. To give a simple example: I need object A to perform action X. Object A needs P, Q and R to perform this action X. Will then Object A retrieve P, Q and R by itself (within action X), or must these values be parameters for action X?

  • Right programing language for developing application for Mac

    - by drasto
    I'm planing to buy Mac. I would like to be able to develop GUI aplication for Mac as well. Currently I develop in C# using VisualStudio as IDE. I also know Java and I'm familiar with NetBeans IDE. Application created in both of this languages can run on Mac (as can NetBeans IDE) but I was told that neither C# nor Java is recomended for MacOS X development. So what language is recomended for MacOS X development ? I guess there is some recomodation from Apple for the developers ? I would prefer Object-oriented easy-to-use programing language (nothing like C) with good IDE that supports GUI creating (GUI designer). Thank you for answers

  • What is your most obfuscated JavaScript example (5 lines maximum)?

    - by snowlord
    JavaScript is known as a language with many weird features. This probably makes it a good language to write extremely obfuscated and hard to understand code in (in the style of The International Obfuscated C Code Contest). What would be your best example of obfuscated JavaScript code (5 lines maximum)? I am thinking that it should be very hard to understand, but also have an element of style or humor in it. And for clarity: using obfuscation tools is not the point, of course. Hand crafting only!

  • Sockets: I/O Error 32

    - by Genesis
    Could someone please explain what an I/O Error 32 refers to in the context of a network socket? I have a multithreaded Socks5 server written using Poco SocketReactors and am getting this error when the server load reaches a certain point. The exception is thrown within my onReadable handlers at the same time across all threads which have connections associated with them. The only other thing I am doing within those threads is std::cout but I am not sure if this is a potential cause.

  • Disabling the "save password" prompt in web browsers

    - by torrtruk
    hi guys. How do I disable the save password prompt in web browsers whenever I'm submitting a form. I've seen a few bank sites where this doesn't come up. Are they doing it through JS or there any http headers or HTML meta tags available to achieve this? I'm trying to do this for a mobile application. Please pour your ideas.

  • What do I need to learn to make a website that can make a text file?

    - by lala
    I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

  • Offer access to a private page without login

    - by dccarmo
    So I've been struggling with a nice and easy way to allow users to access a private page without asking them to fill out a login/password form. What I'm thinking about using right now is for each private page I generate a uniqueid (using php uniqid function) and then send the URI to the user. He would access his private page as "www.mywebsite.com/private_page/13ffa2c4a". I think it's relatively safe and user friendly, without asking too much of information. I thought maybe when the user access this page it would ask for it's e-mail just to be sure, but the best would be nothing at all. Is this really safe? I mean not internet banking safe, but enough for a simple access? Do you think there's a better solution? Thanks. :)

  • How to pass sockets created to another Java Process

    - by whoi
    Hi; We have an application which creates many sockets which belongs to its thread, By design if this application somehow fails, all threads stop which is not wanted. So to overcome this issue, each thread must be separated from the main application, if one of the threads fails, the other ones should be running. One thing in our mind is to pass created socket to another java process, so what is the correct way? An other approach also is welcome? Waiting for your suggestions...

  • Analyzing BSOD without a dump

    - by eeoo2555
    One of the drivers I'm developing has caused a BSOD. Unfortunately a dump file was not created since it was not configured / low resources. I was trying to reproduce this crash but no luck so far. Is there any way to get some info using WinDbg or any other tool? I have this information: A screenshot of the BSOD The .sys file. Its pdb The source code The machine it was crashed on I have everything except the dump itself. Your help will be much appreciated. As I said above, no dump (/minidump) exists. This is the actual problem. For this specific crash, I know I won't be able to get the stack. Just getting the specific line of code will be good enough. Because the BSOD contains the module's address, it seems like there should be a way to detect which line exactly is it. As I mentioned above, I do have the .sys file, the pdb and the source code. This is the specific code taken from MSDN: SYSTEM_SERVICE_EXCEPTION. How can I know from there what was the specific line? and/or the specific exception raised?

  • How to deal with a coworker who keeps asking instead of searching herself?

    - by mafutrct
    I'm lucky enough to share a room with 3 other people at work. One of them, a senior programmer who's very talkative in general, tends to ask me various questions throughout the day. While some of them are surely ' legitimate', many questions could have been answered by putting in just slightly more search effort on their part. I really don't mind be asked stuff, and I can also cope with beginner questions, but this is seriously interrupting my flow. I clearly remember Joel talking about how private offices increase productivity because they prevent too easy questions from being asked. How should I deal with this situation? Getting a private office is out of the question, sadly. It's difficult to approach him directly, and he blissfully ignored the slight hints I tried to give.

    If I have a process that receives signals from other processes, is there a way for me to somehow tell which process (if any) sent a signal? strace lets me trace which signals a process has received, but doesn't allow me to trace who issued them.

  • How to implement a UIViewAutoresizingFlexibleHeight to a UIScrollView using Objective C in iPhone SD

    - by AppleHack23
    Hello, I'm working on multiple applications for my school. I just need this last bit of code and I was wondering how I could implement a UIViewAutoresizingFlexibleHeight into the app for each textfield. What this does is it makes the textfield pop above the keyboard, rather than over lapping it. I have already implemented a UIScrollView, so if someone on here could be pretty descriptive, or post a link to a video, that would be well appreciated. I am new to coding. Thanks very much!!!!
