  • Extract elements from list based on object property type

    - by Dustin Digmann
    Often, I have a list of objects. Each object has properties. I want to extract a subset of the list where a specific property has a predefined value. Example: I have a list of User objects. A User has a homeTown. I want to extract all users from my list with "Springfield" as their homeTown. I normally see this accomplished as follows: List users = getTheUsers(); List returnList = new ArrayList(); for (User user: users) { if ("springfield".equalsIgnoreCase(user.getHomeTown()) returnList.add(user); } I am not particularly satisfied with this solution. Yes, it works, but it seems so slow. There must be a non-linear solution. Suggestions?

  • What is the best strategy for a streaming screen capture application ?

    - by The_AlienCoder
    Ok Ive figured out how to do a screen capture of my desktop using Windows Media Encoder 9 + SDK and saving it as a movie on my hardrive. But now I want to take my project further and stream a realtime screen capture of my desktop . The idea is that users accessing my asp.net website will be able to view whatever Im doing on my desktop in real time via the video streaming from my computer. I really dont need the source code just the best strategy, procedure and server requirements.How will users access the streaming video on my website? Will it work on my godaddy shared hosting account or at what point will I need an upgrade? Will I be saving the stream to a file on the server for users to access or is there a way to stream directly ? I just need someone to point me in the right direction...

  • any open source instant messenger?

    - by George2
    Hello everyone, I need to develop an instant messenger (like MSN Messagner, but only simple and basic function is fine), based on .Net (C#). I want to integrate the instant messenger with my current web site user. I want to know any open source (better C#) instant messenger to reference? BTW: some of the users are using internal IP address (behind a gateway or proxy, like 10.10.xxx.xxx) -- so in this scenario two users can not use point to point message transfer if both of them are behind a gateway? And I think I have to develop a server which acts as an intermediate party to transfer message between two users, correct? thanks in advance, George

  • Clickonce application does not update or launch.

    - by jhunter
    I have a winforms application that I have deployed using clickonce, but the users navigate to a network drive and double click on setup.msi instead of using a webpage to install it. I have two users that have it installed and it's worked in the past. I did an udpate last week and now when the users try to launch the application the window that says "Verifying Application Requirements" pops up then when it disappears nothing happens. The dialog asking if it's ok to update never pops up. The network people have verified that they have permissions on the network drive (though, I would expect an error message if this were the issue). Any clues what could cause this to happen?

  • Problem using mysql joins

    - by mariomario
    I'm fairly new to mysql and I have no idea if I'm heading in the right direction but I'm having trouble with a mysql query. I basically have a table of users id name ---- -------- 1 user1 2 user2 3 user3 4 user4 as well as a table of user attributes id userid attribute ---- ----- ------ 1 1 5 2 1 6 3 2 5 4 3 4 I want to be able to select users that have both the attribute 5 and the attribute 6, so in this case I want to return id name ---- -------- 1 user1 I tried using a join like this. SELECT u.id, u.name FROM users u LEFT JOIN attributes a ON (a.userid = u.id) WHERE a.attribute = 5 AND a.attribute = 6 But obviously that won't work, what is the best way of doing this?

  • How Many HABTM relationships in cakephp is too many?

    - by user559540
    Hi all, I'm struggling with deciding how many HABTM relationships I really need in my cakephp app. I guess I don't quite get what "has" truly means. I don't want to have more HABTM tables than necessary. Here's what I have in my database: Users Properties Leases Payments Repairs user HABTM properties, user HABTM leases, user HABTM users, user HABTM repairs, property hasMany repairs, property hasMany leases, lease hasMany repairs. Also, I have two aliases for my users model (manager and tenant). This is one of the reasons I ended up with so many HABTM relationships, but I'm not sure it's necessary. Do I have too many user HABTM relationships? Would it be better to just have cake recurse through my models? Thanks!

  • Always get the correct datetime?

    - by Jesper Mansa
    I was wandering if there is a way/site/link whith the correct time? Not the servers datetime or the clients datetime. I'm using datetime to count down on my gaming site for when it is the users time to make a play. Users come from all ower the world so using the users client time would not match if its from the US to Europe. Then normally I would use the servers time, but somehow it skips 1.2 hours sometimes? I would like to make sure that everbody makes a timestamp from the same source and that source always is correct! Hoping for help and thanks in advance.

  • Strange Array#each Ruby behaviour

    - by with a dot.
    The question is a bit vague, but I am not really sure why this happens: I have the following code: p user.room.users.length user.room.users.each {|usr| puts "b" } user.room.users.each {|usr| puts "a"; usr.enter(Room[Config::entrance]) } which outputs: 5 b b b b b a a a I also made User#enter count how many times it's been called and it returns 3! I am completely baffled by this behaviour. I doubt the code within User#enter is the cause, but if someone thinks it might be relevant I can provide it (I don't want to clutter the question unnecessarily). Edit If it's relevant I am using ruby-1.9.3-p125

  • Creating user generated reports

    - by Marquinio
    Hello Everyone, I need users to create custom reports. These users do not know any technical skills like SQL. We currently have a custom database report design. So basically whatever the user does on the GUI the application will have to generate the appropriate SQL to generate the report structure. Has anyone done this before? I know there are reporting solutions out there but we already have our own database tables for reporting. We already have a section where users can view reports displayed in HTML. Like for example if user selects a "UserID" and "Accounts" fields from GUI, how would I know that my SQL has to join the USER and ACCOUNTS table? I guess I'm just looking for some ideas to help me solve this problem. Thanks.

  • OpenID login on local development server for google app engine

    - by Alex Jeffery
    Are you able to use open id to log into the local development server with google app engine sdk version 1.4.1 and python 2.5? When I execute this self.redirect(users.create_login_url(continue_url, None, openid_url)) I get redirected to http://localhost/_ah/login rather than the openid url. The openid url and continue url are valid. My app.yaml looks like this - url: /_ah/login_required script: do_openid_login.py - url: /users/(.*) script: routers/user_router.py login: required If I browse to http://localhost/users/ I am also redirected to http://localhost/_ah/login rather than http://localhost/_ah/login_required Is there a config issue or does openid not work locally?

  • Online webcam chat on web page. Free server and easy-to-implement client?

    - by Oskar Kjellin
    I have a client requesting that his users can use their webcams to talk to each other on his web site. From what I've understood the main thing to use for this is Flash. However as I have not written flash I would like to have something really easy to implement. Of course preferrably free (or trial). The idea of this is that everything but the chat alone is in .net. So the users will not use flash until they are actaully going to talk to each other. So there is no use for rooms here. I've been looking into silverlight some as well. But it seems like silverlight does not offer streaming between users..? I know this question has been asked many times here. But I could not find a suitable answer which is why I post a new question.
