  • Why can I not have two SocketServers bound to two different ports in the same application?

    - by uriDium
    I am using .Net 3.5 and Windows XP not sure if any more information is needed. I have an application that creates a socket, binds to a port and starts listening. A client comes and connects and then disconnects no problem. It can then reconnect no problem. If I have to sockets each listening on a different (e.g. 50 000 and 55 000) then it will accept the connection but it will not allow a reconnect. I will post source code if needed but I am assuming that it is just something simple that I am not catching.

  • How can I edit a js file sent by the server before it gets to my browser?

    - by pstone
    During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it, then edit it manually and forward it to the same port. I don't think I can do this by just using pcap, I've read a bit about scapy but I'm not sure if it can help me either. Thanks in advance.

  • Sequential WSASend() calls - can I rely on TCP to put them on the wire in the posting order?

    - by Poni
    On Windows I/O completion ports, say I do this: void function() { WSASend("1111"); // A WSASend("2222"); // B WSASend("3333"); // C } If I got a "write-complete" that says 3 bytes of WSASend() A were sent, is it possible that right after that I'll get a "write-complete" that tells me that some or all of B & C were sent, or will TCP will hold them until I re-issue a WSASend() call with the rest of A's data? Or will TCP complete it automatically?

  • 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. :)

  • Why is Objective-C not very popular outside of the Apple community?

    - by Tattat
    I know that the Apple community – including Mac and iPhone developers – mainly use Objective-C for their development language. But it seems that not many people use Objective-C outside of the Apple community, such as in the Windows or Linux worlds. What are the possible reasons that Objective-C is not particularly popular outside of the Apple community?

  • Impressing Potential Employers

    - by superfly123
    Where I am, I can't afford to get certification. I'm definitely not the best programmer, but I do know my junk. I've been writing software in C++ for over 8 years now and have a very good knowledge of the Win32 API. But when applying for jobs, I get rejected every time I send a resume. I've given my resume to recruitment firms and asked them what they think's wrong with it and they said the only thing they could think of is the fact that I don't have certifications to prove that I know my stuff. But in my resume, I explain my previous work and projects, and also note that upon request they can actually see what I've done. Is there anything that you would suggest that might help others to stop ignoring my resumes? Thank you

  • .NET framework is copied to 'compiler/CLR' and 'GAC?

    - by prosseek
    The book of CLR via C# has this line at page 76. When you install the .NET Framework, tow copies of Microsoft's assembly files are actuall installed. One set is installed into the compiler/CLR directory, and another set is installed into GAC subdirectory I could find the GAC at C:\Windows\Microsoft.NET\assembly, but I couldn't find the compiler/CLR thing. What's the physical directory name of compiler/CLR? I mean, where is it? Why there are two GAC in assembly directory? I find GAC_32 and GAC_MSIL.

  • 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?

  • what is the accepted naming convention for int, string, array, list, object, etc...

    - by RJ
    The company I work for now uses a set naming convention for their C# variables such as iSomeName for int, sSomeName for string, aSomeName for arrays, bSomeName for boolean, dSomeName for datetime and so on. My previous employer did not use the i, s, a, b and d prefixes and just named the variables a good understandable name. My impression is that these prefixes lost favor a while ago and from what I read it is not the current trend. It seems fine to me either way as long as the variable is descriptive enough to understand what it is doing but I was wondering what the now-a-day accepted practice is for naming variables?

  • What type of programs are C/C++ used for now?

    - by Ryan Detzel
    I started off with C in school, went to Java and now I primarily use the P's(Php, Perl, Python) so my exposure to the lower level languages have all but disappeared. I would like to get back into it but I can never justify using C over Perl or Python. What real-world apps are being built with these languages? Any suggestions if I want to dive back in, what can I do with C/C++ that I can't easily do with Perl/Python?
