  • Web.NET event coming in October

    - by Chris Massey
    If you’re a web developer in Europe (or would like an excuse to travel to Europe), you should definitely take a look at the Web.NET event coming in October. It’s being organized by two Italian web maestros (Simone Chiaretta and Ugo Lattanzi) and the session list looks fantastic. The event site pretty much speaks for itself, but here’s a quick version: It’s a free one-day event on October 20th, with a huge variety of great sessions by great speakers, all 100% focused on web development. There’s a pizza-fuelled hackathon in the evening; thrills, spills and hot new skills. It’s a great chance to network with the local (in relative terms) web development community. It’s free (although all donations are very greatly appreciated). It’s in Milan, darling. Here’s what you need to do: Go and register on www.webnetconf.eu, and vote on which sessions you think look the most interesting. I know this will be a difficult process – it’s *very* hard to choose – but persevere! Grab your place when the free tickets become available early next month (places are limited). Come to Milan in October, learn some new skills, meet some great people, and maybe build something awesome if you feel like staying up late. I’ll be there, and hopefully I’ll see you on the day.

  • Recommend a CMS and extension to build an Event Manager [closed]

    - by Haris
    I posted this question on SO but good friends there told me that SE is the better place for these kind of questions and the post was locked there by community. Hence, posting the question here as well: I have a lead to build an event manager solution in LAMP with following functionality: It should handle events by country, city, locality in city, type of event, venue type etc. following are a few user features: to see details of city, venue, event, performer etc. to purchase tickets and reserve tables. to search for events by city, venue, type, performer etc. to manage favorite venues and performers, save events etc. the venues should be able to add their events I plan to use a CMS (Joomla, Drupal etc.) with some ready made extension that provides most of the functionality or provide framework to build upon. Could you guys suggest me a CMS and an extension to build this. I know it is possible to do this in both Joomla or Drupal. What I am looking is the extension that is closest to my requirements whether it is done in Joomla or Drupal, or as a matter of fact any other CMS. Thanks in anticipation!

  • ASP .NET Button event handlers do not fire on the first click, but on the second click after a PostB

    - by John
    Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired. Any ideas? Example of Button Definition (within GetAdministrationInterface) public override Control GetAdministrationInterface() { // more code... Button btn = new Button(); btn.Text = "Click Me!"; btn.Click += new EventHandler(Btn_Click); // more code... } Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something } Page_Load Method that calls GetAdministrationInterface protected void Page_Load(object sender, System.EventArgs e) { if (!Page.IsAsync) { List<AdministrationInterface> interfaces = <DATABASE CALL>; foreach(AdministrationInteface ai in interfaces) { placeholderDiv.Controls.Add(ai.GetAdministrationInterface()); } } }

  • Is there a better way to write this repetitive event-declaration code in C# when implementing an int

    - by Damien Wildfire
    I have a lot of code like the following, where I explicitly implement some events required by an interface. public class IMicrowaveNotifier { event EventHandler<EventArgs> DoorClosed; event EventHandler<EventArgs> LightbulbOn; // ... } public class Microwave : IMicrowaveNotifier { private EventHandler<EventArgs> _doorClosed; event EventHandler<EventArgs> IMicrowaveNotifier.DoorClosed { add { lock (this) _doorClosed += value; } remove { lock (this) _doorClosed -= value; } } private EventHandler<EventArgs> _lightbulbOn; event EventHandler<EventArgs> IMicrowaveNotifier.LightbulbOn { add { lock (this) _lightbulbOn += value; } remove { lock (this) _lightbulbOn -= value; } } // ... } You can see that much of this is boilerplate. In Ruby I'd be able to do something like this: class Microwave has_events :door_closed, :lightbulb_on, ... end Is there a similar shorter way of removing this boilerplate in C#? Update: I left a very important part out of my example: namely, the events getting implemented are part of an interface, and I want to implement it explicitly. Sorry for not mentioning this earlier!

  • Ubuntu - Upgrade to 10.4 - general error mounting filesystems

    - by JC Denton
    Hello All, Using upgrade manager I upgraded my 8.x LTS installation to 10.4. After rebooting the system failed encountered an error and dropped into the recovery console. It appeared to be a problem caused by ureadahead as described here: http://ubuntuguide.net/howto-fix-ureadahead-problem-after-upgrading-to-ubuntu-10-04. So I renamed ureadahead.conf to ureadahead.moved (after remounting the partition rw). this did not help so I renamed the file back again. After rebooting the following error appears: ureadahead terminated with status 5. udev_monitor_new_from_netlink: error getting socket: Invalid Argument mountall:mountall.c:3204 assertion failed in main: udev_monitor = udev_monitor_new_from_netlink(udev,"udev") init: mountall main process (2532) killed by ABRT signal. General error mounting filesystems How will I get my system to boot again properly? thanks

  • General purpose ticketing/tech support system [closed]

    - by crazybyte
    Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

  • "RFC 2833 RTP Event" Consecutive Events and the E "End" Bit

    - by brian_d
    Hello, I can send out a RFC 2833 dtmf event as outlined at http://www.ietf.org/rfc/rfc2833.txt When I do set the E "End" bit, but leave it as 0, I get the following behaviour: If for example keys 7874556332111111145855885#3 were pressed, then ALL events would be sent and show up in a program like wireshark, however only 87456321458585#3 would sound. So the first key (which I figure could be a separate issue) and any repeats of an event (ie 11111) are failing to sound. In section 3.9, figure 2 of the above linked document, they give a 911 example. Here all but the last event have the E bit set. When I set the bit for all numbers, I never get an event to sound. I have thought of a couple possible thing but do not know if they are the reason: 1) figure 2 shows payload types of 96 and 97 sent. I have not nor know how to exactly. In section 3.8, codes 96 and 97 are described as "the dynamic payload types 96 and 97 have been assigned for the redundancy mechanism and the telephone event payload respectively" 2) In section 3.5, "E:", "A sender MAY delay setting the end bit until retransmitting the last packet for a tone, rather than on its first transmission" Does anyone have an idea of how to actually do this? I have also fiddled around with timestamp intervals and the RTP marker. Any help is greatly appreciated. Here is a sample wireshark event capture of the relevant areas: 6590 31.159045000 xx.x.x.xxx --.--.---.-- RTP EVENT Payload type=RTP Event, DTMF Pound # (end) Real-Time Transport Protocol Stream setup by SDP (frame 6225) Setup frame: 6225 Setup Method: SDP 10.. .... = Version: RFC 1889 Version (2) ..0. .... = Padding: False ...0 .... = Extension: False .... 0000 = Contributing source identifiers count: 0 0... .... = Marker: False Payload type: telephone-event (101) Sequence number: 0 Extended sequence number: 65536 Timestamp: 0 Synchronization Source identifier: 0x15f27104 (368210180) RFC 2833 RTP Event Event ID: DTMF Pound # (11) 1... .... = End of Event: True .0.. .... = Reserved: False ..00 0000 = Volume: 0 Event Duration: 2048

  • Coding events. What they actually are about, and are they worth it?

    - by BKC
    I'm a relatively new programmer, but am very much interested in it. I enrolled to this coding event (Yahoo! Hack India, to be precise), and got invited after the pre-coding contest. The event is like a contest where developers create an application in 24 hours, In group or individually. I've never been to such an event before, and certainly don't know anyone who did. So, here are my questions. First of all, is it worth it? What if we don't get any ideas in the first place to start with? I'm not actually a developer, I'm an electrical engineering student who just completed his 2nd semester. So will be able to match up to the level of other developers who will be there? Any other advice/suggestions Thank you in advance.

  • Listening For and Raising Events in the BLL

    - by OneSource
    I'm working on a WinForms .Net Recording App and I have a RecordingMgr in my BLL to listen for new events captured by another class. I want to display the events in my UI and I'm stuck as to what's the best way to do this. I can think of a few scenarios to handle this but all of them seem sub-optimal: Listen for and handle Recorded Events in both the UI and in the RecordingMgr After receiving the event in the RecordingMgr, raise it again so that the UI can pick it up Create a variable in RecordingMgr (e.g., a BindingList) that the UI can bind to and update it when an Event is received Ditch the RecordingMgr and just put the event recording logic in the UI What's the best approach? Something above or something else?

  • design for interruptable operations

    - by tpaksu
    I couldn't find a better topic but here it is; 1) When user clicks a button, code starts t work, 2) When another button is clicked, it would stop doing whatever it does and start to run the second button's code, 3) Or with not user interaction, an electrical power down detected from a connected device, so our software would cancel the current event and start doing the power down procedure. How is this design mostly applied to code? I mean "stop what you are doing" part? If you would say events, event handlers etc. how do you bind a condition to the event? and how do you tell the program without using laddered if's to end it's process? method1(); if (powerdown) return; method2(); if (powerdown) return; etc.

    I can and would love to use boost or std for this. Sorry - I am new to C++. So I created a really simple program like: #include <iostream> #include <string> using namespace std; class superman { public: string punch(){return cout << "superman: I hit the bad guy!" << endl;}; }; int main() { superman clark; clark.punch(); cin.get(); } I want to add an event listner that would tell me when clark punched and cout something like "superman punched!". How to add such event listner and event function to my class?

  • How to identify the source of a text selection event coming from a CompareEditorInput in eclipse?

    - by tangens
    In my eclipse plugin I have the following code: public class MyHandler extends AbstractHandler { @Override public Object execute( ExecutionEvent event ) throws ExecutionException { ISelection sel = HandlerUtil .getActiveWorkbenchWindowChecked( event ) .getSelectionService() .getSelection(); if( sel instanceof TextSelection ) { IEditorPart activeEditor = PlatformUI .getWorkbench() .getActiveWorkbenchWindow() .getActivePage() .getActiveEditor(); IEditorInput editorInput = activeEditor.getEditorInput(); if( editorInput instanceof CompareEditorInput ) { // here are two possible sources of the text selection, the // left or the right side of the compare editor. // How can I find out, which side it is from? } } return null; } } Here I'm handling a text selection event coming from an CompareEditorInput, i.e. the result of comparing two remote revisions of a file with subclipse. Now I want to handle the text selection properly. For that I have to know if it selects some text inside the left side editor or inside the right side editor. How can I find that out?

  • Ruby/Rails display general screen when modifications being performed on server

    - by john chan
    I have a ruby on rails app running a server and sometimes it needs to be taken down for updates/etc. As of now, one way I see to have a general display screen during update periods (when the app is down) is to substitute the files within /srv/www/ directory to just have it display a general screen everywhere that the user could possibly navigate to. I also thought of having a central controller file that connects all others (essentially a main) but this seems counter intuitive for rails. There are many external links to these different components of the site that the user could navigate to from outside and I need to make sure that they always receive this general update screen when the app is taken down for a little. I was wondering if anyone had any other ideas.... maybe a library or something like that, I can't seem to find anything online. any suggestions would be appreciated. Thanks

  • Efficient algorithm for finding largest eigenpair of small general complex matrix

    - by mklassen
    I am looking for an efficient algorithm to find the largest eigenpair of a small, general (non-square, non-sparse, non-symmetric), complex matrix, A, of size m x n. By small I mean m and n is typically between 4 and 64 and usually around 16, but with m not equal to n. This problem is straight forward to solve with the general LAPACK SVD algorithms, i.e. gesvd or gesdd. However, as I am solving millions of these problems and only require the largest eigenpair, I am looking for a more efficient algorithm. Additionally, in my application the eigenvectors will generally be similar for all cases. This lead me to investigate Arnoldi iteration based methods, but I have neither found a good library nor algorithm that applies to my small general complex matrix. Is there an appropriate algorithm and/or library?

  • PHPMyAdmin: "General relation features: Disabled"

    - by Simón
    I've been looking around for something like this for a while, and I've found some tips on similar issues, but not exactly the same. I really don't know what to do. I downloaded and installed WAMP, and I have a MySQL and PHPMyAdmin setup according to common indications that can be found everywhere (securing MySQL root account, etc.). When I log into PHPMyAdmin (either as root or as pma), I see the following message at the bottom of the page: The additional features for working with linked tables have been deactivated. To find out why click here. And when following the link, got a page with the following: Server: localhost $cfg['Servers'][$i]['pmadb'] ... OK $cfg['Servers'][$i]['relation'] ... OK General relation features: Disabled $cfg['Servers'][$i]['table_info'] ... OK Display Features: Disabled $cfg['Servers'][$i]['table_coords'] ... OK $cfg['Servers'][$i]['pdf_pages'] ... OK Creation of PDFs: Disabled $cfg['Servers'][$i]['column_info'] ... OK Displaying Column Comments: Disabled Bookmarked SQL query: Disabled Browser transformation: Disabled $cfg['Servers'][$i]['history'] ... OK SQL history: Disabled $cfg['Servers'][$i]['designer_coords'] ... OK Designer: Disabled Somebody please explain to me, why the heck if all settings are "OK" the features remain "Disabled"? Note: at first all the settings were "not OK" and I managed to add the settings to config.inc.php, and then created the tables using scripts/create_tables.php. Of course I have already tried restarting the server or clearing the browser cache (several times, so I am sure the problem comes elsewhere).

  • Advice on Computer Specs for overall development/general use machine

    - by Ender
    At the moment I am restricted to a laptop with 512MB of RAM, a 120GB HDD and a 1.5GHz Intel processor for all my development and general browsing needs, and as you can probably tell using it for anything modern is a painful experience. As a result I've decided to buy myself a new desktop computer, one that will stand the test of time and one that can be upgraded easily. Rather than build the machine myself I've decided to go through Dell as I've had good experiences with them when purchasing computers for my family. I've had my eye on this as it's got a good amount of RAM, has a decent-rated processor and isn't priced too badly. http://www1.euro.dell.com/uk/en/home/Desktops/inspiron-580/pd.aspx?refid=inspiron-580&s=dhs&cs=ukepp1&~oid=uk~en~20211~inspiron-580_d005827~~ Intel® Core™ i5 Processor 750 (2.66GHz, 8MB) Genuine Windows® 7 Home Premium 64bit - English Display Not Included ATI Radeon™ HD 5450 1GB DDR3 graphics 6144MB Dual Channel DDR3 [3x2048] Memory 1TB (7200rpm) SATA Hard Drive DVD +/- RW Drive (read/write CD & DVD) with DVD Burn software 1 year of coverage included with your PC McAfee® Security Centre - 15 Month Protection - English After the pain of using a slow laptop for all this time the main thing I want is speed. I may look to play a couple of basic games on it, nothing too powerful. Obviously I'll be doing some development on it too so it'll have to be able to handle the latest IDE's and Database tools like SQL Server pretty quickly. Finally, should I ever need to improve it I'd like to be able to add more RAM and change some of the parts. I wouldn't have thought this would be a problem but a few people I've spoken to have said that the amount of RAM the motherboard can handle isn't that great. Is this true? How long can I expect to be using this computer before it's too slow? Thanks in advance for the help.

  • UK Connected Systems User Group - Udi Dahan Event Topic change

    - by Michael Stephenson
    Hi Just wanted to get the word out about a change to the may user group event.  Udi Dahan will present a new topic which he has not presented in the UK before.  Details below. To register for this event please refer to: http://ukconnectedsystemsusergroup.org/UpcomingEvents.aspx Title: High Availability - A Contrarian View   Abstract: Many developers are aware of the importance of high availability, critically analyzing any single points of failure in the infrastructure. Those same developers rarely give a second thought to the periods of time when a system is being upgraded. Even if all the servers are running, most systems cannot function in-between versions. Yet with the increased pace of business, users are demanding ever more frequent releases. The poor maintenance programmers and system administrators are left holding the bag long after the architecture that sealed their fate was formulated. Join Udi for some different perspectives on high availability - architecture and methodology for the real world.

  • Clarification about Event Producer in StreamInsight

    - by sandy
    I need a small clarification about streamInsight, I know by doc's that StreamInsight can handle multiple concurrent Events. But will the event producer be a separate function, for ex: I need to watch a folder for new Files becoz all my sensors il write readings every day in a new file in particular drive. Method 1: FileSystemWatcher: These is the traditional approach where we write a service using FileSystemWatcher to watch a folder for new files,etc.. Upon receiving event from FileSystemWatcher il perform some operations on these files. How to do these using streamInsight??? I came know that using IObservable i can push events to StreamInsight. But is there anything to watch folder is sreamInsight like FileSystemWatcher. OR In order to raise events to streamInsight do we need to use FileSystemWacther? Any suggestion regarding these is highly appreciated. Thank in Advance
