  • UDP Code client server architecture

    - by GameBuilder
    Hi I have developed a game on android.Now I want to play it on wifi or 3G. I have game packets which i want to send it form client(mobile) to server then to another client2(mobile). I don't know how to write code in Java to send the playPackets continuously to server and receive the playPacket continuously from the server to the clients. I guess i have to use two thread one for sending and one for receiving. Can someone help me with the code, or the procedure to write code for it. Thanks in advance.

  • AJAX Requests & Client-Side JavaScript

    - by Sarah24
    I am new to AJAX and trying to understand a question I've been given: A HTTP request is generated by a form which contains some drop-down list. When the form is submitted, a new web page is displayed with some relevant text information (which is dependent on the list item selected). Now, the same parameters are sent to the server via an AJAX request, and the same text information is returned. Q. What tasks would the client-side JavaScript have to do to ensure a valid request was constructed and sent? Any useful links or quick explanations greatly appreciated.

  • Delivering estimates and client expectations?

    - by FishOrDie
    When a client asks for an estimate on how long it would take to develop different sections of an app, is it best to give them a total amount or what it would take for each section? Is it better/more common to give a range of hours/days or just a single number? Do you think most clients feel that if a programmer says it should take 50 hours that they should be billed for 50 hours? If I say it would take 50 and it actually takes 60, do I tell them in advance that I'm going over on my estimate or just charge what was originally quoted?

  • /etc/profile not being sourced

    - by Marc
    For 11.04, I did a fresh install of my system. Part of that install was to install rvm, which sticks a rvm.sh in /etc/profile.d/. This doesn't work as /etc/profile (which loads each +r in /etc/profile.d/*.sh) is not being loaded. According to the documentation, the profile is only sourced if bash is run in login. To verify this, I invoked bash --login, after which rvm was available. This has worked for me in previous versions of Ubuntu without any configuration. That is, a fresh install of 10.10 will correctly source profile/.d. My question is: is there anything I'm doing wrong, or are there some new assumptions being made in Natty that have broken this? My current workaround is to source /etc/profile in ~/.bashrc (which is awful as profile is meant to load before bashrc's, but does the trick).

  • transfer Thunderbird (17) Profile on Win7 to Ubuntu 12.04

    - by William Curran
    I want to transfer Thunderbird Profile on Win7 to thunderbird (17) Ubuntu 12.04. I already copied the profile folder from Windows to Ubuntu and modified progile.ini on the ubuntu machine to include [Profile] Name=Bill IsRelative=1 Path=(the name of the transfered profile folder) I think the problem is that the Win. TB profile content (files and folder structure) look VERY different that the that of the unbuntu TB profile's that was created on installation. The Ubuntu install is new where as the Win TB has undergone many updates. Seems the system for profile storage has changed drastically. I tried to start TB in safe mode but could't get the path correct to start TB in the terminal with the -safe-mode switch. What can I do? Bill

  • Desktop GUI Client - Remote RDBMS communication

    - by magom001
    Sorry if I am asking a trivial question but I have been searching for a while without any luck. I need to design a system and I am looking for advice on the technology that should be used. The layout is very simple: it is a sales application with a centralized database and multiple clients. Each salesperson has GUI app installed on his/her laptop that should be able to connect to the database to retrieve data and upload data (i.e. register new orders). My question is the following: how should the communication between the client and the server be implemented? I doubt that connecting directly to the RDBMS is a good idea... Should I use web-services? XML-RPC? How to implement authentication and encode the data? Thanks for your advice!

  • Unable to delete Gmail profile in Outlook 2010

    - by Michele
    I used to have 2 Gmail profiles set up in Outlook 2010. I initially had it set up using IMAP, but I deleted it (or so I thought), and re-set it up the old-fashioned way without IMAP. Then finally, I deleted the 2nd Gmail profile altogether. So now I only have ONE Gmail profile set up in Outlook 2010 and it works fine. The problem is that the original Gmail IMAP folder for the 2nd Gmail account is still in my list of folders when I use Outlook. I've already disabled IMAP via my Google Gmail account. But I am unable to delete the folder from Outlook 2010. I have checked in the account settings and it is NOT in my list of email profiles or the data files. Has anyone else had this problem?

  • J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

    - by Mike
    J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

  • How do I Set PATH in /etc/profile.d?

    - by Rodrigo Sasaki
    I'm using zsh as my shell, and I'm trying to configure my environment. I usually define my $JAVA_HOME variable by creating a file: /etc/profile.d/java.sh with the following content export JAVA_HOME=/path/to/jdk export PATH=$JAVA_HOME/bin:$PATH then I logout and back in, and it all works, but for some reason the PATH variable is not set. It recognizes JAVA_HOME, but not the new PATH, see this terminal snippet: ~ echo $JAVA_HOME /usr/lib/jvm/jdk1.8.0_05 ~ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games and I confirmed it by trying to run a command form the jvm ~ java -version zsh: command not found: java the PATH doesn't include the $JAVA_HOME as it should. is there something else I should check? EDIT I have checked that if I run source /etc/profile.d/java.sh it all runs correctly and my variables get set as they should, but shouldn't the scripts in /etc/profile.d run automatically?

  • Should your client be able to view your project management board?

    - by bizso09
    We're making a bespoke software for our client and use Codebase for our project management. Is it a good idea to let our client view our project management board? The advantages that we thought of are that this would enhance the cooperation between the client and the dev team, following agile practices. He would essentially become part of our team. It would also reduce communication overhead and make sure we're on the same page. The client could track the progression of the system and make suggestions along the way on the user stories. In addition, he could submit bugs or feature requests. The disadvantages that we though of are that some aspects of the board might be too technical to the client. He would suggest changes to the user stories too often and he might view some content that we normally wouldn't want our client to see. For example, when we compromise on technology or functionality, the client might question that and insist on doing things one way or the other.

  • cron job for updating user profile data imported via facebook connect

    - by Abidoon Nadeem
    I want to write a cron job for updating user profile data on my website that I pull for users that register via facebook connect on my website. The objective is to keep their profile data on my website in sync with their profile data on facebook. So if a user updates their profile picture on facebook. I want to update his profile picture on my website as well via a cron job which will run every 24 hours. I wanted to know if this is possible and secondly if this is in violation of facebook privacy policy. Based on my research it seems doable but I wanted to know if anyone has already done something like this before. It would really help.

  • Iphone does not recognize reneweed ad hoc provising profile

    - by Amnon Dekel
    I installed a new version of an app we are developing, and also a new ad hoc provisioning profile (the old one had expired). I removed the app and profile from the phone and from itunes. Added the new profile and app to itunes and synched. All seemed well- the new profile was on the phone and the new app too. But when trying to launch the app, I get an alert: "the application cannot be opened because the provisioning profile has expired". I removed and reinstalled. I rebooted the phone. Nothing helped. Any ideas? Thanks

  • Asp.net profile in a separate assembly

    - by Shimrod
    Hi everyone, I have a web application which uses membership and profiles. I successfully used the WebProfileBuilder extension, so my profile class is correctly generated, and is working nicely. However, after a new request of my client, I need now to move that profile management part into another assembly (so I'd be able to get profile information in a windows service running on the same machine). What I made is created the new assembly, moved my generated profile file, and tried to use it from the other assembly, but without any success. I always get a SettingsPropertyNotFoundException. My tought is that the profile system doesn't know where to find its connection information, so I tried to add the connectionstring and provider in the app.config of this assembly, but this doesn't seem to work. What am I missing ? Is it possible to do ? Thanks in advance!

  • Make windows 7 client compatible with windows 2003 server

    - by caspert
    Hi, I am sysadmin for a small business with 30 clients. We have a server running windows 2003 and all the client-computers run windows XP. Now this is not an important issue, but it would be nice if it worked. My personal (home) computer is running windows 7 RC. When I bring my home-computer to work and log into the network with domain\username it logs me in just fine. Although, approving my profile, letting me into the network, including all network drives and printers, it does not download the profile fully. I do believe it might be getting the roaming profiles. So all my user- items, documents etc. attached to the profile does not show up on Windows 7. Is there any way to make it fully download the profile? as it does with Windows XP.

  • Client A can ping server S, but client B cannot

    - by Soundar Rajan
    I moved the question to here from stackoverflow.com http://stackoverflow.com/questions/2917569/unable-to-ping-server-from-client-b-but-able-to-ping-from-client-a-please-help I am trying to configure a IIS 6.0/Windows Server 2003 web server with a ASP.net application. When I try to ping the server from client computer A I get the following: PING 74.208.192.xxx ==> Ping fails PING 74.208.192.xxx:80 ==> Ping succeeds! From client computer B, BOTH the pings fail.

The server is outside (a virtual server hosted by an ISP) I have an ASP.NET application in a virtual directory on the server. In IE or firefox, if I enter http://74.208.192.xxx/subdir/subdir/../Default.aspx, it works from both the clients! The server has default firewall settings but web server enabled (Port 80 is open).

  • Get user profile size in vbscript

    - by Cameron
    Hello, I am trying to get the size of a user's local profile using VBScript. I know the directory of the profile (typically "C:\Users\blah"). The following code does not work for most profiles (Permission Denied error 800A0046): Dim folder Dim fso Set fso = WScript.CreateObject("Scripting.FileSystemObject") Set folder = fso.GetFolder("C:\Users\blah") MsgBox folder.Size ' Error occurs here Is there another way to do this? UPDATE: I did some deeper digging and it turns out that the Permission Denied error occurs if permission is denied to some subfolders or files of the directory whose size I wish to get. In the case of user profiles, there's always a few system files that even the Administrator group does not have permission to access. To get around this, I wrote a function that tries to get the folder size the normal way (above), then, if the error occurs, it recurses into the subdirectories of the folder, ignoring folder sizes that are permission denied (but not the rest of the folders). Dim fso Set fso = WScript.CreateObject("Scripting.FileSystemObject") Function getFolderSize(folderName) On Error Resume Next Dim folder Dim subfolder Dim size Dim hasSubfolders size = 0 hasSubfolders = False Set folder = fso.GetFolder(folderName) ' Try the non-recursive way first (potentially faster?) Err.Clear size = folder.Size If Err.Number <> 0 then ' Did not work; do recursive way: For Each subfolder in folder.SubFolders size = size + getFolderSize(subfolder.Path) hasSubfolders = True Next If not hasSubfolders then size = folder.Size End If End If getFolderSize = size Set folder = Nothing ' Just in case End Function

  • Active FTP client blocked on Windows XP

    - by Ian Hannah
    Summary We have a FTP server (running in active mode). We have an FTP client which is connecting to the server, carrying out a task and then closing the connection. The FTP Client can perform this operation on multiple threads. Problem We have a situation where customers are experiencing occasional failures to carry out operations on a FTP connection. The actual connection has been made to the server but when the server attempts to return data on the data port if fails. Observations We have a simple test FTP client which is running two separate threads. Each thread is performing a recursive listing of files from a root directory. With the firewall running on the client machine the hang happens within a few minutes. If the firewall is turned off on the client machine, the test application seems to run correctly. This does point to a potential firewall issue. However, with the firewall on we can list files on our company FTP server without any issues. If the simple test FTP client runs a single thread then we do not experience any problems whether or not the firewall is turned on. We have another simple test FTP client which was running 4 threads (with each opening a new FTP connection, doing a directory listing and closing the FTP connection as fast as possible) overnight with the firewall turned off. With the firewall turned on it fails in a short space of time. The confusing thing is that if the test FTP client and the FTP server are run on the same machine the failure occurs even though the firewall is turned off. This means that the problem may not be firewall related. Any help with what this could be would be much appreciated. Thanks Ian

  • Profiles and using the local profile for a domain user

    - by Harry
    I’m having some trouble with profiles and would like to reach out for some help. I’ve tried to do some research to help myself along, but I’m not making much progress on my own. I’ve pretty much taken over the sys admin duties for my small lab, I don’t have much experience to justify it besides I’m the only with the time and dedication to go at it (The environment was in a state of disrepair). My network and domain I look over are extremely small by most standards, about 10 users at a time. They are pretty intensive activity on the network, and we do work with fairly large files. None of the network is online, which is nice at the moment because it allows me not to have another headache. On to my profile problem, I have set up roaming profiles for the users in the network. Now after a little research, I think I will be switching this to a hybrid of folder redirection and roaming profiles as this seems to best practice. I also don’t want the users having to wait for a long time if they have a bloated profile. Now I’ve finally got a build working using MDT. We have Mac Pros, and it wasn’t fun getting everything to play nice. The way I did this was by setting up a reference computer and installing all the software and tools that each user would need and editing the settings preferences to how we would need them. I think used MDT to do a sys prep and capture to create the image of my reference computer. Using the reference image I can push out my images to the rest of the desktops in my environment. The issue I’m having is when we join the computer to domain. The user can login and operate fine on the computer, but I’d like a more. When the user is logged on with their domain user name they lose a lot of the icons I had on my reference image, as well as the desktop background and some other miscellaneous settings. I would love to have the user log on using their domain user name and see the icons and desktop environment as I had it setup on the reference computer. I’m not sure if it is possible, or something simple that I’m missing, but any help would be greatly appreciated!

  • Roaming profile is not loaded when user's password expires and is changed

    - by JCS
    Our password policy makes users change pw every 30 days, when this happens they sometimes find they are logged on with a local profile and none of their settings. This generally only happens when the PC was slow at logging onto the network, but in this case I know it had plenty of time to do so. I can't work out why this is happening, is it related to a slow link?

  • Configuration of LDAP client on 12.04

    - by user106515
    We have here a way to log in the computers base on Ldap(openldap). You can use any seat with the login/pass you have. Well my problem is that everything worked fine till I had to upgrade Ubuntu to the last version (12.04). Now, it is far from impossible to log in because you only can choose administrator account! That would be my issue; I want to Lightdm allow me to choose the user e.g : pagonzalez or rmlago or whatever the login-name you have. I´ve been searching for 2 days now, and nothing comes up! Hope somebody here has any idea about it!
