  • How to use Socket in AC3 or other solution for using embedded flash without cross domain policy?

    - by monkey_boys
    How to use Socket in AC3 or other solution for using embedded flash without cross domain policy? I would like to create a project that uses HTTP to post to some website's form by using embedded flash in a webpage. When I finished the project, I tried to embed on the local computer and that work fine but when I uploaded to a web server in the some domain and requested to some different domain it stopped working. I know that's the security of ac3 but I would like to use embedded flash. Does anybody have any idea about this?

  • How can I upload data using ftp, http, or a socket from a spreadsheet with VBA for Microsoft Office?

    - by luiscolorado
    I have an Excel spreadsheet, and I want to put a button on it, so users will be able to upload their data to an http/ftp server, or send the data to the server using a socket directly. I have noticed that some people creates an ftp script to do. First of all, I'm not sure that everybody has ftp on their Windows machine, and secondly, I would prefer to use a method that allows me to better monitor the progress of the upload. For example, I want to know if the user id/password failed, if the transmission completed successfully, of if there were any other kind of errors with the receiving server. Thank you.

  • can't connect Java client to C server.

    - by nexes
    I have a very simple server written in C and an equally simple client written in Java. When I run them both on the same computer everything works, but when I try to run the server on computer A and the client on computer B, I get the error IOException connection refused from the java client.

  • Advice for a computer science sophomore in college?

    - by RDas
    Hi Everyone! I'm a sophomore in college majoring in Computer Science and Math. I have always loved programming. I started programming in C when I was nine years old and over the years I've picked up Visual Basic, C#, Java, C++, JavaScript, Objective-C, Python, Ruby, elementary Haskell and elementary Erlang, and I learned Perl back in the day which I've mostly forgotten. I have not done much network programming. I have done CGI programming, but that was about six/seven years ago. I've done some socket programming and written (school) programs to do interprocess communication, which I understood and liked. I'm taking a course on client/server programming and another one on network security next semester, which I am really looking forward to. I'm seeking advice on how to proceed with future learning. I've mostly done application (mobile and desktop) development, not much of web development. I'd like to pick up some web development this coming semester. Since I know Ruby and Python, should I start by learning Django and/or Rails? Any other suggestions on starting web development? I have a good understanding of HTML and CSS. Also, I'd also like to know how hard it is to pick up and be good (read: productive) in functional programming languages coming from a purely structured/object oriented background? I've been reading up on Erlang and Haskell, and I'd like to know your opinions on whether it's worth my time trying to learn them. What about Lisp, Scheme and other functional languages? Any help/ideas would be really appreciated.

  • What are your suggestions on learning how to think?

    - by Jonathan Khoo
    First of all, this is not the generic 'make me a better programmer' question, even though the outcome of asking this question might seem similar to it. On programmers.SE, I've read and seen these get closed here, here, here, here, and here. We all know there are a multitude of generic suggestions to hone your programming skills (e.g reading SO, reading recommended books, following blogs, getting involved in open-source projects, etc.). This is not what I'm after. I also acknowledge the active readership on this web site and am hoping it works in my favour by yielding some great answers. From reading correspondence here, there appears to be a vast number of experienced people who are working, or have worked, programming-related fields. And most of you can convey thoughts in an eloquent, concise manner. I've recently noticed the distinction between someone who's capable of programming and a programmer who can really think. I refuse to believe that in order to become great at programmer, we simply submit ourselves to a lifetime of sponge-like behaviour (i.e absorb everything related to our field by reading, listening, watching, etc.). I would even state that simply knowing every single programming concept that allows you to solve problem X faster than everyone around you, if you can't think, you're enormously limiting yourself - you're just a fast robot. I like to believe there's a whole other face of being a great programmer which is unrelated to how much you know about programming, but it is how well you can intertwine new concepts and apply them to your programming profession or hobby. I haven't seen anyone delve into, or address, this facet of the human mind and programming. (Yes, it's also possible that I haven't looked hard enough too - sorry if that's the case.) So for anyone who has spent any time thinking about what I've mentioned above - or maybe it's everyone here because I'm a little behind in my personal/professional development - what are your suggestions on learning how to think? Aside from the usual reading, what else have you done to be better than the other people in your/our field?

  • Thinking skills to be a good programmer

    - by Paul
    I have been programming for last 15 years with non-CS degree. Main reason I got into programming was that I liked to learn new things and apply them to my work. And I was able to find and fix programming errors and their causes faster than others. But I never find myself a a guru or an expert, maybe due to my non-CS major. And when I saw great programmers, I observed they are very good, much better than me of course, at solving problems. One skill I found good in my mid-career is thinking of requirements and tasks in a reverse order and in abstract. In that way, I can see what is really required for me to do without detail and can quickly find parts of solution that already exist. So I wonder if there are other thinking skills to be a good programmer. I've followed Q&As below and actually read some of books recommended there. But I couldn't really pickup good methods directly applicable for my programming work. What non-programming books should a programmer read to help develop programming/thinking skills? Skills and habits to develop to be good at programming (I'm a newbie)

  • Natural talent vs experience [on hold]

    - by Tord Johansson Munk
    Hi i have a question for you guys if you had a choice of hiring one of two programmers. One of them is a natural born programming talent, he has been programming since he was 14 year old and he has been programming all sorts of things by him self, 3d renders,games,his own frameworks, he is really good at algorithms and problem solving. He is now about 25 years old and is looking for a job after some unchallenged years of college the only experience he has is working on his own/university stuff and some open source project. This guy spends all his free time programming and has several pet projects at home. The other person is a 37 year old career programmer. He has been programming since he graduated from university at the age of 26 and have been working since then. He did not have an interest in programming before university. During his studies he discovered that programming was fun and challenging but it never was a "passion". During his career he mainly worked with "enterprise" platforms such as .net or javaEE. He mainly have done database business applications and thus is lacking skills of the young talent like abstract problem solving or algorithms. But he know the tools he has been using during the years and is reliable and almost always makes his boss happy. He keeps him self updated in the platform and tools he has and is using. But outside the office walls he don't touch any code at all. Witch one would you hire? Would you favor one of them in certain projects? Do you think that if the young talent learns his tools he will be a better programmer than the older one? Would your decision be different if both of them where lacking a degree? or if only one of them was lacking a degree be the old and experienced or the young genius.

  • Why do sockets not die when server dies? Why does a socket die when server is alive?

    - by Roman
    I try to play with sockets a bit. For that I wrote very simple "client" and "server" applications. Client: import java.net.*; public class client { public static void main(String[] args) throws Exception { InetAddress localhost = InetAddress.getLocalHost(); System.out.println("before"); Socket clientSideSocket = null; try { clientSideSocket = new Socket(localhost,12345,localhost,54321); } catch (ConnectException e) { System.out.println("Connection Refused"); } System.out.println("after"); if (clientSideSocket != null) { clientSideSocket.close(); } } } Server: import java.net.*; public class server { public static void main(String[] args) throws Exception { ServerSocket listener = new ServerSocket(12345); while (true) { Socket serverSideSocket = listener.accept(); System.out.println("A client-request is accepted."); } } } And I found a behavior that I cannot explain: I start a server, than I start a client. Connection is successfully established (client stops running and server is running). Then I close the server and start it again in a second. After that I start a client and it writes "Connection Refused". It seems to me that the server "remember" the old connection and does not want to open the second connection twice. But I do not understand how it is possible. Because I killed the previous server and started a new one! I do not start the server immediately after the previous one was killed (I wait like 20 seconds). In this case the server "forget" the socket from the previous server and accepts the request from the client. I start the server and then I start the client. Connection is established (server writes: "A client-request is accepted"). Then I wait a minute and start the client again. And server (which was running the whole time) accept the request again! Why? The server should not accept the request from the same client-IP and client-port but it does!

  • Getting Indy Error "Could not bind socket. Address and port are already in use"

    - by M Schenkel
    I have developed a Delphi web server application (TWebModule). It runs as a ISAPI DLL on Apache under Windows. The application in turn makes frequent https calls to other web sites using the Indy TIdHTTP component. Periodically I get this error when using the TIdHTTP.get method: Could not bind socket. Address and port are already in use Here is the code: IdSSLIOHandlerSocket1 := TIdSSLIOHandlerSocketOpenSSL.create(nil); IdHTTP := TIdHTTP.create(nil); idhttp.handleredirects := True; idhttp.OnRedirect := DoRedirect; with IdSSLIOHandlerSocket1 do begin SSLOptions.Method := sslvSSLv3; SSLOptions.Mode := sslmUnassigned; SSLOptions.VerifyMode := []; SSLOptions.VerifyDepth := 2; end; with IdHTTP do begin IOHandler := IdSSLIOHandlerSocket1; ProxyParams.BasicAuthentication := False; Request.UserAgent := 'Test Google Analytics Interface'; Request.ContentType := 'text/html'; request.connection := 'keep-alive'; Request.Accept := 'text/html, */*'; end; try idhttp.get('http://www.mysite.com......'); except ....... end; IdHTTP.free; IdSSLIOHandlerSocket1.free; I have read about the reusesocket method, which can be set on both the TIdHttp and TIdSSLLIOHandlerSocketOpenSSL objects. Will setting this to rsTrue solve my problems? I ask because I have not been able to replicate this error, it just happens periodically. Other considerations: I know multiple instances of TWebModule are being spawned. Would wrapping all calls to TIdHttp.get within a TCriticalSection solve the problem?

  • Socket errors of 10048 on the client? Possible causes?

    - by Earlz
    Hello, I'm writing a custom TCP server and client and on doing a ton of requests (60,000 to be exact) I begin to get this socket error of 10048, which should mean "the address is already in use." The error keeps happening unless I pause the process for like 2 or 3 minutes and then begin it again, and then it begins to bring up the same error a short while after restarting it. If I pause the client process and restart the server process, I still get the same error on the client. So it is a complete client side problem. This does not make sense though, this error only usually occurs when binding and this error happens on the client and not the server. What could be the possible reasons for it? A small excerpt of my initialization: TcpClient client = new TcpClient(); client.Connect("XXXXX -- some ip", 25000); client.NoDelay = true; NetworkStream clientStream = client.GetStream(); Also, everything else seems to be working fine(including the amount of time it takes to send back and forth) and this works perfectly when using 127.0.0.1 but when putting it on another LAN computer I begin to get the 10048 error. Is there something wrong with how I initialize it? What else could cause this error on the client side?

  • How to pull UIImages from NSData from a socket.

    - by Jus' Wondrin'
    Hey all! I'm using ASyncSocket to move some UIImages from one device over to another. Essentially, on one device I have: NSMutableData *data = UIImageJPEGRepresentation(image, 0.1); if(isRunning){ [sock writeData:data withTimeout:-1 tag:0]; } So a new image will be added to the socket every so often (like a webcam). Then, on the other device, I am calling: [listenSocket readDataWithTimeout:1 tag:0]; which will respond with: - (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag { [responseData appendData:data]; [listenSocket readDataWithTimeout:1 tag:0]; } Essentially, what I want to be able to do is have an NSTimer going which will call @selector(PullImages): -(void) PullImages { In here, I want to be able to pull images out of ResponseData. How do I do that? There might not be a complete image yet, there might be multiple images, there might be one and a half images! I want to parse the NSData into each existing image! } Any assistance? Thanks in advance!

  • How to host WCF service and TCP server on same socket?

    - by Ole Jak
    Tooday I use ServiceHost for self hosting WCF cervices. I want to host near to my WCF services my own TCP programm for direct sockets operations (like lien to some sort of broadcasting TCP stream) I need control over namespaces (so I would be able to let my clients to send TCP streams directly into my service using some nice URLs like example.com:port/myserver/stream?id=1 or example.com:port/myserver/stream?id=anything and so that I will not be bothered with Idea of 1 client for 1 socket at one time moment, I realy want to keep my WCF services on the same port as my own server or what it is so to be able to call www.example.com:port/myWCF/stream?id=222...) Can any body please help me with this? I am using just WCF now. And I do not enjoy how it works. That is one of many resons why I want to start migration to clear TCP=) I can not use net-tcp binding or any sort of other cool WS-* binding (tooday I use the simpliest one so that my clients like Flash, AJAX, etc connect to me with ease). I needed Fast and easy in implemrnting connection protocol like one I created fore use with Sockets for real time hi ammount of data transfering. So.. Any Ideas? Please - I need help.

  • Where can a self-teacher learn general good programming habits and conventions?

    - by lucid
    A few mistakes and general childishness in early adulthood have left me in a situation where I work a menial job, with no possibility (in the near future) of attending school. I aspire to one day work in the programming field (gaming specifically), after proving myself on the indie end of things. I've gotten very confident in C++, java, and python, and I find I'm able to solve any problem I want either from previous experience, or from scouring the web for help. The solutions work, and with each attempt they become more readable, maintainable, and extensible. But this is because I'm learning from mistakes and bad programming and design habits I feel I might have avoided with actual schooling. General tips like: "if it's hard to read or getting long, or you're writing it twice, it should be in one or more functions." or "design all your classes before you start coding, so you don't have to rewrite classes later when you discover an unforeseen dependency" Is there a good book or website for learning general good programming practices and design habits? Also, naming and format conventions. I realize sometimes development houses have their own conventions, but things like "Classes in python usually have the first letter of each word capitalized". I'd like to be able to show some source code to a potential employer, and be prepared when for what's expected on a team. Is there some central database of naming and formatting conventions somewhere? Also, feel free to give any thoughts on whether or not the self-teach, garner some indie sales, use them as your resume' route is realistic

  • How do you portray to non programmers what programming involves?

    - by JD Isaacks
    I get casually asked a lot to take a couple days to teach someone how to program. Most people really think they can learn what I know in a few days. When I tell them I have been doing this for many years and I can't teach them to be a programmer in a few days, they look at me like I am being a jerk and just don't want to help them. I think this is because when I say I am a programmer, or I programmed this. I truly think most people do not realize that I mean I wrote the code that makes it up. I think that they think I mean I configured it, like when you say, "I programmed my VCR." Does anyone else think this? Whats your experience?

  • Recommended books on math for programmers

    - by Anto
    Some programmers do, besides programming, like math (others don't). What books on math do you recommend programmers who like math to read? There are books which present concepts which are applicable in programming and/or computer science, other books about things which will fascinate programmers etc. Books on applying math to programming are okey, but they should be mainly about math (and not programming). Motivate your answers, with focus on why programmers should read the book(s).

  • Overhead of TLS/SSL on a TCP socket connection?

    - by TK Kocheran
    Is there any bandwidth overhead on using SSL on a TCP connection? I understand, of course, the processing/memory usage overhead in encrypting and decrypting packets, but as far as bandwidth is concerned, what is the difference, if any? For example, given a XML file which is 64KB, will there be any tangible difference in the transfer size of the file over HTTP vs. HTTPS? (Ignoring mod_deflate and mod_gzip, of course)

  • Installing MySQL without root access

    - by vinay
    I am trying to install MySQL without root permissions. I ran through the following steps: Download MySQL Community Server 5.5.8 Linux - Generic Compressed TAR Archive Unpack it, for example to: /home/martin/mysql Create a my.cnf file in your home directory. The file contents should be: [server] user=martin basedir=/home/martin/mysql datadir=/home/martin/sql_data socket=/home/martin/socket port=3666 Go to the /home/martin/mysql directory and execute: ./scripts/mysql_install_db --defaults-file=~/my.cnf --user=martin --basedir=/home/martin/mysql --datadir=/home/martin/sql_data --socket=/home/martin/socket Your MySQL server is ready. Start it with this command: ./bin/mysqld_safe --defaults-file=~/my.cnf & When I try to change the password of MySQL it gives the error: Cannot connect to mysql server through socket '/tmp/mysql.sock' How can I change this path and see whether the mysql.sock is created or not?

  • What are some great resources about programming contemporary GUIs and GUI architecture patterns?

    - by snitko
    So I've read Martin Fowler's old blog post http://martinfowler.com/eaaDev/uiArchs.html which describes various approaches to building GUI from an architecture point of view, discussing patterns and how they were used. But this blog post was written in 2006. Since then, there must have been some new ideas in the field? I was curious whether anyone knows about a similar guide to GUI architectures, but describing contemporary systems? The reason I'm interested in something abstract and theoretical to read is because it really is difficult and time consuming to ACTUALLY learn how ALL of the contemporary frameworks work, given their diversity and the diversity of the languages they are written in. I am primarily a web developer, so I'm familiar with Rails and some Javascript frameworks. But I would also like to know how GUI is built on Android or in Cocoa or in Windows, but without having to learn all of those things.
