  • Network Communication program in python

    - by lamnep
    Hi all, Basically what I'm trying to achieve is a program which allow users to connect to a each other over a network in, essentially, a chat room. What I'm currently struggling with is writing the code so that the users can connect to each other without knowing the IP-address of the computer that the other users are using or knowing the IP-address of a server. Does anyone know of a way in which I could simply have all of the users scan the IP range of my network in order to find any active 'room' and then give the user a chance to connect to it? Also, the hope is that there will be no need for a central server to run this from, rather every user will simply be connected to all other user, essentially being the server and client at the same time.

  • Does Oracle 10g automatically escape double quotes in recordsets?

    - by bitstream
    I am encountering an interesting issue with an application that was migrated from Oracle 9i to 10g. Previously, we had a problem when a field contained double quotes since Oracle recordsets encapsulated fields in double quotes. Example: "field1"||"field2"||"field "Y" 3"||"field4" Since the move to 10g, I believe that the Oracle client-side driver is parsing the double quotes and replacing them with &quot; Unfortunately I don't have an old 9i environment to test my theory. Have you seen similar behavior or can someone validate if my theory is true?

  • clrear coockies and cache from site

    - by salvadore
    Every time i updat my website system UI\Jquery. Users complain that things are not working for them and that they have bugs. Users are internet\computer dummies so they dont know how to clear the coockies or the cache of the browser, so i need to connect to each one of their computers and do it by myself. I spend lots off hours doing it and they always complain. Some of the useres use Chrome, some Firefox. Googled and found no solution for this, Is there any client code operation that will command the browser to clrear its cache or even pop up browser window wich will ask user to confirm the clear?

    Mise à jour du 10/06/10 Chrome OS pourrait passer du Cloud au client léger Les applications hébergées pourront l'être sur un ordinateur distant : les professionnels en ligne de mire ?

  • Why Is it better to use unreadable bytes for client server communication?

    - by Alessa
    I'm composing communication lyrics for client-server and what am I thinking about: "authme username passord" (maybe encrytped) "accept" "get archive of H2O from 03.02.2005 to 20.12.2064" transferring binary structure or "error descrtiption" why I always need to do something like 0x0FA52FD + CRC 0x0D34423 + CRC ... I can see some secure reasons but I think it's not the real reason so why I can't use strings in client-server communication?

  • Is there a way to schedule the downloads in Transmission BitTorrent Client?

    - by Ankit
    I have added a couple of torrent files to Transmission BitTorrent Client to be downloaded. I have a limited internet speed so I can't start all of them in a single go; so I have to peep in after every 30 minutes or so to start downloading other file(added to the client). I don't want to peep in 30 minutes; looking for a way to schedule the downloads (i.e when one download completes other files can start automatically) without manual intervention.

    After testing the windows client for U1 sync, I decided to test the preferences' settings, and tried to remove the association for the WinXP station from which I was working.

  • How to intercept raw soap request/response (data) from WCF client

    - by JohnIdol
    This question seems to be pretty close to what I am looking for - I was able to setup tracing and I am looking at the log entries for my calls to the service. However I need to see the raw soap request with the data I am sending to the service and I see no way of doing that from the SvcTraceViewer (only log entries are shown but no data sent to the service) - am I just missing configuration? Here's what I got in my web.config: <system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Verbose" propagateActivity="true"> <listeners> <add name="sdt" type="System.Diagnostics.XmlWriterTraceListener" initializeData="App_Data/Logs/WCFTrace.svclog" /> </listeners> </source> </sources> </system.diagnostics> Any help appreciated!

  • Asynchronous HTTP Client for Java

    - by helifreak
    As a relative newbie in the Java world, I am finding many things frustratingly obtuse to accomplish that are relatively trivial in many other frameworks. A primary example is a simple solution for asynchronous http requests. Seeing as one doesn't seem to already exist, what is the best approach? Creating my own threads using a blocking type lib like httpclient or the built-in java http stuff, or should I use the newer non-blocking io java stuff - it seems particularly complex for something which should be simple. What I am looking for is something easy to use from a developer point of view - something similar to URLLoader in AS3 - where you simply create a URLRequest - attach a bunch of event handlers to handle the completion, errors, progress, etc, and call a method to fire it off. If you are not familiar with URLLoader in AS3, its so super easy and looks something like this: private void getURL(String url) { URLLoader loader = new URLLoader(); loader.addEventListener(Event.Complete, completeHandler); loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler); loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); URLRequest request = new URLRequest(url); // fire it off - this is asynchronous so we handle // completion with event handlers loader.load(request); } private void completeHandler(Event event) { URLLoader loader = (URLLoader)event.target; Object results = loader.data; // process results } private void httpStatusHandler(Event event) { // check status code } private void ioErrorHandler(Event event) { // handle errors }

    - by Clone of Anton Makrushin
    Hello. I have no good script-writing experience. So, I have a list created on MOSS 2007 with about 1000 elements and attachments enabled. I need to attach to each list item file (*.jpg) from a local folder. I doesn't have administrator privileges at MOSS server, only contributor rights Here is my script: $web = new-Object system.Net.WebClient $web.Credentials = [System.Net.CredentialCache]::DefaultCredentials $web.Headers.Add("user-agent", "PowerShell Script") $web.UploadFile('http://ruglbsrvsps/IT/Lists/Test1/', 'C:\temp\Attachments\14\Img1.jpg' ) Test1 - target list; Item1, Item2, Item3 - list items, without attachments, created manually When I run script, it returns byte array and does not upload file to the list item. Can you fix my script or advice better solution for my task (attach bulk of files to the MOSS list items, only contributor rights for target Sharepoint 2007 list) Thank you.

  • "Unable To Load Client Print Control" - SSRS Printing problems again

    Please forgive me as my head is spinning. I have tried so many solutions to this issue, that I'm almost not sure where I am at this point. At this point in time I have these issues in my Production, Test, and Dev environments. For simplicity sake, I will just try to get it working in Dev first. Here is my setup: Database/Reporting Server (Same server): Windows Server 2003 SP2 SQL Server 2005 SP3 Development Box: Windows 7 Visual Studio 2008 SP1 SQL Server 2008 SP1 (not being used in this case, but wanted to include it in case it is relative) Internet Explorer 8 Details: * I have a custom ASP.NET application that is using ReportViewer to access reports on my Database/Reporting Server. * I am able to connect directly to Report Manager and print with no trouble. * When I view source on the page with ReportViewer, it says I'm am using version 9.0.30729.4402 . * The classid of the rsclientprint.dll that keeps getting installed to my c:\windows\downloaded program files directory is {41861299-EAB2-4DCC-986C-802AE12AC499}. * I have tried taking the rsclientprint.cab file from my Database/Reporting Server and installing it directly to my Development Box and had no success. I made sure to unregister the previously installed dll first. I feel like I have read as many solutions as I can, and so I turn to you for some assistance. Please let me know if I can provide further details that would be helpful. Thanks

  • How to call RequiredFieldValidator on client before postback

    - by Si
    I've inherited some code which breaks a page up into tabs using divs. On the first page there are many required field and regex validators. The problem is a user can switch to another tab, trigger a postback and fail the validators on the first page, leaving things in a mess. What I want to be able to do is perform the validation on the first page as a user selects another tab, thus preventing them from moving to a new tab until the first page is valid. <ul> <li><a href="#tab1">Tab 1</a> </li> <li><a href="#tab2" onclick="return isValid();">Tab 2</a></li> <li><a href="#tab3" onclick="return isValid();">Tab 3</a></li> </ul> Where isValid needs to fire off the validators. Thanks!

  • Win CE 6.0 client using WCF Services

    - by Sean
    We have a Win CE 6.0 device that is required to consume services that will be provided using WCF. We are attempting to reduce bandwidth usage as much as possible and with a simple test we have found that using UDP instead of HTTP saved significant data usage. I understand there are limitations regarding WCF on .NET Compact Framework 3.5 devices and was curious what people thought would be the appropriate way forward. Would it make sense to develop a custom UDP binding, and would that work for both sides? Any feedback would be appreciated. Thanks.
