  • Communication protocols in UDP

    - by Betamoo
    After many hours, I have discovered that the given udp server needs the following steps for a successful communication: 1- Send "Start Message" on a given port 2- Wait to receive from server on any port 3- Then the port dedicated to you to send further data to the server equals the port you have received on it + 1 So I am asking if this kind is a known protocol/handshaking, or it is only special to this server?? PS: All above communication were in udp sockets in C# PS: Related to a previous question: http://stackoverflow.com/questions/2757868/about-c-udp-sockets Thanks

  • What is a service provider?

    - by Joey
    Sorry if this is a silly question but I am a C developer who just happen to be in a meeting with a bunch of .NET guys and over heard their conversation. They were sketching out a design and constantly talk of service provider, services and spring. Instead of looking silly by asking them, I just decided to post here. BTW, I am doing device driver development (have been for more than 10 years using C) and NEVER heard of service provider.

  • Any netbeans features that will make my day?

    - by Kris
    Hi all, I've recently gotten quite fond of netbeans for my php work because of the XDebug integration. It has made me all but forget about textmate (which imho still beats netbeans for the little things) What do you think is the one awesome netbeans feature I should know about, and more importantly why and how do I use it? I'm asking this to optimize my skills in the use of the IDE and based on the idea that what works well for others might just work for me (and hopefully others).

  • log4j properties file: how to configure ?

    - by EugeneP
    Is it right that the procedure of using log4j looks like this: 1) put a .properties file somewhere in a project folder 2) in an initialization method, that runs only once, invoke PropertyConfigurator.configure("path_to_file"); 3) in every method we need to use logger we define a static logger variable and simply invoke getLogger(class) I'm asking you this: what if the initialization module is not defined? Where to put "log4j.properties" file so that we wouldn't need to invoke propertyconfigurator.configure at all, or if it's not possible, is it ok to invoke PropertyConfigurator.configure("path_to_file") in every method that uses a logger?

  • Excel VBA Application.OnTime. I think its a bad idea to use this... thoughts either way?

    - by FinancialRadDeveloper
    I have a number of users I support that are asking for things to happen automatically ( well more automagically but that's another point!). One want events to happen every 120 secs ( see my other question ) and also another wants 1 thing to happen say at 5pm each business day. This has to be on the Excel sheet so therefore VBA as addins etc will be a no no, as it needs to be self contained. I have a big dislike of using Application.OnTime I think its dangerous and unreliable, what does everyone else think?

  • What does the Microsoft.WebApplication.targets import do in VS 2010 web application projects?

    - by Simon
    Visual Studio 2010 seems to insist on having this import in web application projects <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> What does this import give us and is it really required? On a side note if you remove this import with a text editor Visual studio will re-add it. The reason i am asking is when the project is compiled on a build server that target does nor exists because visual studio is not installed.

  • Any downsides to UPX-ing my 32-bit Python 2.6.4 development environment EXE/PYD/DLL files?

    - by Malcolm
    Are there any downsides to UPX-ing my 32-bit Python 2.6.4 development environment EXE/PYD/DLL files? The reason I'm asking is that I frequently use a custom PY2EXE script that UPX's copies of these files on every build. Yes, I could get fancy and try to cache UPXed files, but I think a simpler, safer, and higher performance solution would be for me to just UPX my Python 2.6.4 directory once and be done with it. Thoughts? Malcolm

    Around how much space does a Sharepoint Collaboration Portal use up by default (when newly created)? Just asking because I had one created but I'm thinking of using a Team Site site template--if the client won't be utilizing the default "features" of a Collaboration Portal.

    I don't whether this is even possible which is obviously why I am asking this question :) Is it in any way possible to leverage functionality the Cellular Emulator on a REAL PHYSICAL device?? :) So when I test it on my device, I really do not have to send real SMS(s) to test my MessageInteceptor. On a sidenote, why does MessageInteceptor fails after several messages to intercept messages?? :( Thanx a lot in advance :)

  • Crash firefox using Javascript

    - by user324675
    I'm part of a testing team and have been tasked with "behaving badly" using javascript in a firefox browser. I've tried these methods to take the browser down http://www.yuki-onna.co.uk/browserdeath.html but none of them do anything worse than cause a popup asking to shut down the script. Any other ideas?
