• Sending Facebook notifications

  - by antpaw

  Hey i have a little facebook iframe application written with rails and the facebooker plugin. I can loop through the users friends and see whether they also have this application. To do this I use a fql qeury, and my own html (no fbml). Now i want to create a button right beside every friend who doesn't have this app, that sends an invite massage. Is it possible to do this without this FBML/JS voodoo? I looked through the RESTful api but the only thing i could found was this deprecated method :( Can someone provide me an code example on how to do this? I really don't want to use this FBML stuff because it doesn't fit into the ui concept of the app, but if that the only way, please explain how to do this (every fbml tag I've tried is just invisible :( ) Thanks a lot.

• Gecko/Firefox support for HTML5 Notifications

  - by jAndy

  Hi Folks, I'm wondering if there is any build-in support for the HTML5 Notification feature in Gecko browsers so far? Maybe some hidden developer thingy ? I'm aware of WebKits window.webkitNotifications which works great, so, is there a Firefox implementation ? update After searching and reading some w3c HTML5 specs, I'm maybe a little bit off here. I can't find any Notification feature anywhere there. Am I facing wrong facts here? Is that just a "very own webkit implementation" ?

• sql server 2008 notifications

  - by Alexander Stalt

  C#, VS 2005, Sql Server 2008 I have a database on a remote server. It has a table table1. Several clients works with it. Every(each?) client can change content of table1. Every(each?) client must represent actual content of this table. So I need some algorythm (pattern) to keep clients represent actual content of table1. I know that sql server 2008 supports notification mechanism (reporting services). How can I use it for my task ?

• UIScrollView notifications

  - by ryyst

  Hi, I'm coding an app that works much like Apple's Weather.app: There's a UIPageControl at the bottom and a UIScrollView in the middle of the screen. In my code, I implemented the - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView method to figure out when the user did move to a new page. If they move to a new page, I load the adjacent pages' data, as to make further page-switching faster. (In one of Apple's examples, the - (void)scrollViewDidScroll:(UIScrollView *)sender is used, but that causes my app to shortly hang when loading a new page, so it's not suitable.) That code works very well. I'm using scrollRectToVisible:: to programmatically scroll inside the scrollview when the user clicks the UIPageControl. The problem is that the scrollRectToVisible: doesn't post a notification to the UIScrollViewDelegate when it's done scrolling - so the code responsible for loading adjacent pages never get's called when using the UIPageControl. Is there any way to make the UIScrollView notify its delegate when it gets called by the scrollRectToVisible: method? Or will I have to use threads in order to prevent my app from freezing? Thanks! -- Ry

• Software Update Notifications

  - by devio

  I am considering implementing some sort of Software Update Notification for one of the web applications I am developing. There are several questions I came across: Should the update check be executed on the client or on the server? Client-side means, the software retrieves the most current version information, performs its checks, and displays the update information. Server-side check means the software sends its version info to the server, which in turn does the calculations and returns information to the client. My guess is that server-side implementation may turn out to be more flexible and more powerful than client-side, as I can add functionality to the server easily, as long as the client understands it. Where should the update info be displayed? Is it ok to display on the login screen? Should only admins see it? (this is a web app with a database, so updating requires manipulation of db and web, which is only done by admins). What about a little beeping flashing icon which increases in size as the version gets more obsolete every day ;) ? Privacy issues Not everybody likes to have their app usage stats broadcast over the internet. TheOnion question: What do you think?

• Is NServiceBus suitable for general as well specific client notifications

  - by Pratik

  I am looking at various options for a WCF based publish subscribe framework. Say I have one WCF web service that will be the publisher and 1000 clients registered as subscriber. For some published messages all clients will be interested but at the same time I wish the ability to notify a single client with a specific message. On receiving notification the client will call other web service methods on the web service. Is NServiceBus suitable for this kind of scenario ? If I use MSMQ for transport does it mean that every PC where the client is installed requires a queue to be created ?

• Firefox extension dev: observing preferences, avoid multiple notifications

  - by Michael

  Let's say my Firefox extension has multiple preferences, but some of them are grouped, like check interval, fail retry interval, destination url. Those are used in just single function. When I subscribe to preference service and add observer, the observe callback will be called for each changed preference, so if by chance user changed all of the settings in group, then I will have to do the same routine for the same subsystem as many times as I have items in that preferences group. It's a great redundancy! What I want is observe to be called just once for group of preferences. Say extensions.myextension.interval1 extensions.myextension.site extensions.myextension.retry so if one or all of those preferences are changed, I receive only 1 notification about it. In other words, no matter how many preferences changed in branch, I want the observe callback to called once.

• Web Services c#, Sending notifications Clients

  - by Diode

  I want to send a notification (say a string) to subscribers(subscribers ip addresses are in a database on the server side) by calling another method. when ever I call that method the output becomes error-some. [WebMethod] public string GetGroupPath(string emailAddress, string password, string ipAddress) { //SqlDataAdapter dbadapter = null; DataSet returnDS = new DataSet(); string groupName = null; string groupPath = null; SqlConnection dbconn = new SqlConnection("Server = localhost;Database=server;User ID = admin;Password = password;Trusted_Connection=false;"); dbconn.Open(); SqlCommand cmd = new SqlCommand(); string getGroupName = "select users.groupname from users where emailaddress = "+"'"+ emailAddress+"'"+ " and "+ "users.password = " + "'" +password+"'"; cmd.CommandText = getGroupName; cmd.Connection = dbconn; SqlDataReader reader = null; try { reader = cmd.ExecuteReader(); while (reader.Read()) { groupName = reader["groupname"].ToString(); } } catch (Exception) { groupPath = "Invalied"; } dbconn.Close(); dbconn.Open(); if (groupName != null) { string getPath = "select groups.grouppath from groups where groupname = " + "'" + groupName + "'"; cmd.CommandText = getPath; cmd.Connection = dbconn; try { reader = cmd.ExecuteReader(); while (reader.Read()) { groupPath = reader["grouppath"].ToString(); } } catch { groupPath = "Invalied"; } } else groupPath = "Invalied"; dbconn.Close(); if (groupPath != "Invalied") { dbconn.Open(); string getPath = "update users set users.ipaddress = "+"'"+ipAddress+"'"+" where users.emailaddress = " + "'" + emailAddress + "'"; cmd.CommandText = getPath; cmd.Connection = dbconn; cmd.ExecuteNonQuery(); dbconn.Close(); } NotifyUsers(); //NotifyUsers nu = new NotifyUsers(); //List<string> ipList = new List<string>(); //ipList.Add("192.168.56.1"); //nu.Notify(); return groupPath; } private void NotifyUsers() { Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); byte[] ipb = Encoding.ASCII.GetBytes("255.255.255.255"); IPAddress ipAddress = new IPAddress(ipb); IPEndPoint endPoint = new IPEndPoint(ipAddress, 15000); string notification = "new_update"; byte[] sendBuffer = Encoding.ASCII.GetBytes(notification); sock.SendTo(sendBuffer, endPoint); sock.Close(); } This is what has to be basically done. in the server side I have a listening thread and it gets notification when the server sends data( assume for now the database contains client ip address). then ever I call the web method it gives a error "invalid IPAddress" atline byte[] ipb = Encoding.ASCII.GetBytes("255.255.255.255"); thank you :) since this is my first ever post please be kind enough to give me a better feedback too :) thaks

• Sub-viewController doesn't get autorotation notifications, bug?

  - by Shizam

  If I have a view (and its controller) and I override the willAnimateRotationToInterfaceOrientation method so I can respond to autorotation events everything works fine and dandy. Now if I create another viewController and add its view to the first viewController's view via: [firstViewController.view addSubview:secondViewController.view] The secondViewController's willAnimateRotationToInterfaceOrientation method isn't called. What gives? Thanks, Sam

• Suggestions for performance improvement surrounding sending email notifications?

  - by jcmoney

  It takes around a couple of seconds for my app to execute the code to send an email right now on a test server with nothing much else running. Not sure if this is typical/expected. I'm also using the php framework Kohana's email helper and not php's mail directly out of convenience if that matters. Is it always just better to schedule a cron job to send emails every 5 min or so? Or should I be able to send emails immediately and I'm just not doing something right? What the script does is insert a row into the db and notifies the relevant group that the row was created. The groups are usually < 20 people so I just do a loop calling Kohana's email helper each time for each member of the group.

• Pushing notifications to a JavaScript?

  - by Michael Stum

  I'm just wondering if there is a way to have a server push information to a JavaScript function. Essentially I have a Dashboard-type page that has a javaScript function to get updates from the server and update the dashboard. I would like my server to be able to "ping" the JS. I don't even know how that could be possible (I'm guessing Twitter and Facebook use polling?), but I'd thought I ask. I heard of Comet, but I don't know if that works with a plain standard IIS 7 installation? (It's a SharePoint 2010 site if that matters in any way) If I understand it correctly, Comet is essentially a constantly open connection, so it seems like it's actually the opposite of what I want (reducing # of requests and therefore load)

• Where to add an observer to the NotificationCenter in a UITableViewController

  - by Saifis

  I want to send a notification from a UITableViewController-A to UITableViewController-B. I was adding the observer in the initwithCoder of the UITableViewController that is supposed to catch the notifications. The classes are correlated as folows RootViewController ===NavigationController-A =====UITableViewController-A ===NavigationController-B =====UITableViewController-B I need to add the observer before the views are actually loaded because notifications may be sent before the view is called. However I have been told that initializing in the initWithCoder method in a UIViewController is not advisable, and was told to add the observer in the AppDelegate. Are there any other suggestions for doing this?

• Why do toast notifications die if delayed?

  - by ubershmekel

  I'm not sure this is the exact cause of my problem but I'll explain the 2 symptoms I noticed: If I put a break point on a Toast.makeText(..).show(), step over, then wait a few seconds before running, the toast will never appear. I have a location callback that tries to show a toast, but it never appears. Maybe I'm doing something else wrong, this is the line in question in my open source distress signal app. Any help or pointers would be appreciated, --uber

• Toastr.js notifications as modal notfication

  - by Maxsteel

  I know it's not what toastr (or toast notifs in general) are meant to be used for, but I want to use them as a modal notification. My idea is following. On toast show: toastr.options.onShown = function() { //Create an overlay on the entire page} Overlay: #overlay { background-color: rgba(0, 0, 0, 0.8); z-index: 999; position: absolute; left: 0; top: 0; width: 100%; height: 100%; display: none; } And on toast close: toastr.options.onHidden = function() { //make overlay go away } Also, I'm setting timeout of toast to 0 so it won't disappear by itself. Question: I want the toast notification to stay atop the overlay and not behind it as overlay will cover everything. How can I do it?

• Push Notifications in Android Platform

  - by Vinod

  I am looking to write an app which received pushed alerts from a server. I found a couple of methods to do this. 1) SMS - Intercept the incoming SMS and initiate a pull from the server 2) Poll the server periodically Each has its own limitations. SMS- no guarantee on arrival time. Poll may drain the battery. Do you have a better suggestion please?. Thanks much.

• What is the application that displays notifications in Lubuntu 12.04 and how to remove it?

  - by cipricus

  I get all the time notifications in the upper right corner and as a tray icon for all kind of actions, especially downloads. What app is that in Lubuntu? (it is not notify-isd) Is it possible to set what notifications to see? If not, how to remove this completely? Update edit: Removing notification-demon (that being it seems the culprit, as an answer suggests) involves removing some important applications: Lubuntu-desktop is a metapackage I guess. But what about removing deluge and update-notifier? Can I add these back without getting back the notifier?? I do not want in any case to remove these two.
