  • Connecting data to a GUI - OOP

    - by tau
    I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

  • Does SQL Server 2005 error message numbers back to the asp.net application?

    - by Duke
    I'd like to get the message number and severity level information from SQL Server upon execution of an erroneous query. For example, when a user attempts to delete a row being referenced by another record, and the cascade relationship is "no action", I'd like the application to be able to check for error message 547 ("The DELETE statement conflicted with the REFERENCE constraint...") and return a user friendly and localized message to the user. When running such a query directly on SQL Server, the following message is printed: Msg 547, Level 16, State 0, Line 1 <Error message...> In an Asp.Net app is this information available in an event handler parameter or elsewhere? Also, I don't suppose anyone knows where I can find a definitive reference of SQL Server message numbers?

  • Planning a competition

    - by Jérôme
    I need to produce the schedule of a sport-event. There are 30 teams. Each team has to play 8 matches. This means that it is not possible for each team to compete again all other teams, but I need to avoid that two team compete more than once against each other. My idea was to generate all possible matches (for 30 teams: (30*29)/2 = 435 matches) and select from this list 120 matches (8 match for each team: 8 * 30 / 2 = 120 matches). This is where I'm having a hard time: how can I select these 120 matches? I tried some simple solutions (take first match of the list, then the last, and so on) but they don't seem to work with 30 teams. I also tried to generate all possible match combination and find which one is working but with 30 team, this is too much calculation time. Is there an existing algorithm that I could implement?

  • How to apply encoding when reading from a serial port

    - by rross
    I'm reading data from a serial port. I read this posting: http://social.msdn.microsoft.com/Forums/en-US/vbgeneral/thread/a709d698-5099-4e37-9e10-f66ff22cdd1e He is writing about many of the issues I have encounter, but in his writing he refers to using: System.Text.Encoding.GetEncoding("Windows-1252"). The problem I'm having is when and how to apply this. There are three potitional spots in my opinion. When the serial port object is define: private SerialPort comport = new SerialPort(); The Event handler: comport.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); Or when reading the data: string data = comport.ReadExisting(); No matter where I add it. I seem to get errors. How would one use Encoding?

  • How to shutdown local tomcat server when closing browser window?

    - by agez
    Hi, I hava a web app running on a local tomcat server. When the user starts the app (via desktop shortcut) the server starts and the app is opened in a browser window. But when the user just clicks on the close button to stop the application the server is still running in the background - that's annoying. I tried to utilize the "unonload" and "onbeforeunload" events from javascript but unfortunately these events are also fired on some other requests in the app. So I can't use them, except I do a lot of refactoring. Does anyone have an idea for a possible solution? Btw, what I find interesting is the behaviour of Visual Studio when debugging a web application. When I close the browser window Visual Studio also gets a trigger to stop debug mode. So it seems it somehow notices the close event of the browser window, which would be exactly what I need. But I don't know how they do it... Cheers, Helmut

  • Monitoring an audio line.

    - by Stefan Liebenberg
    I need to monitor my audio line-in in linux, and in the event that audio is played, the sound must be recorded and saved to a file. Similiar to how motion monitors the video feed. Is it possible to do this with bash? something along the lines of: #!/bin/bash # audio device device=/dev/audio-line-in # below this threshold audio will not be recorded. noise_threshold=10 # folder where recordings are stored storage_folder=~/recordings # run indefenitly, until Ctrl-C is pressed while true; do # noise_level() represents a function to determine # the noise level from device if noise_level( $device ) > $noise_threshold; then # stream from device to file, can be encoded to mp3 later. cat $device > $storage_folder/`date`.raw fi; done;

  • Trigger button click with JavaScript on Enter key in Text Box

    - by ziondreams
    I have one text input and one button (see below). How can I use JavaScript to trigger the button's click event when the Enter key is pressed inside the text box? There is already a different submit button on my current page, so I can't simply make the button a submit button. And, I only want the enter key to click this specific button if it is pressed from within this one text box, nothing else. <input type="text" id="txtSearch" /> <input type="button" id="btnSearch" value="Search" onclick="doSomething();" /> Update: I'd like to accept my own answer below, but since that is now allowed I will accept the next best solution.

  • Passing Data from Usercontrol to controller

    - by nitinkhanna
    Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

  • Call a JavaScript function in a Google Chrome window from a vb.net program

    - by user1464827
    I am having a real problem with this. I want to know if it is possible to run/call a javascript function in a Google Chrome web browser window from a VB.net application. The scenario is that i want to monitor the pc activity (which i know how to) and then if a certain event is met (for example, high ram usage) then it calls a JavaScript function in a Google Chrome web browser window so the website is updated. Sort of like a bridge. The only bit it need to know is the vb.net code for how to access a chrome window and invoke a javascript function if its possible. I assume i will need to use process handlers? Any help is appreciated.

  • Counts of events grouped by date in python?

    - by Sologoub
    This is no doubt another noobish question, but I'll ask it anyways: I have a data set of events with exact datetime in UTC. I'd like to create a line chart showing total number of events by day (date) in the specified date range. Right now I can retrieve the total data set for the needed date range, but then I need to go through it and count up for each date. The app is running on google app engine and is using python. What is the best way to create a new data set showing date and corresponding counts (including if there were no events on that date) that I can then use to pass this info to a django template? Data set for this example looks like this: class Event(db.Model): event_name = db.StringProperty() doe = db.DateTimeProperty() dlu = db.DateTimeProperty() user = db.UserProperty() Ideally, I want something with date and count for that date. Thanks and please let me know if something else is needed to answer this question!

  • Counting array in API JSON Response

    - by bryan
    I'm trying to do a simple count of how many refunds are in my Stripe Response but count() isn't working and I don't really know any other way of achieving this. Could anyone point me in the right direction? $retrieve_event = Stripe_Event::retrieve("evt_00000000000000"); $event_json_id = json_decode($retrieve_event); $refund_array = $event_json_id->{'data'}->{'object'}->{'refunds'}; die(count($refund_array)); This is the response of $retrieve_event { "created": 1326853478, "livemode": false, "id": "evt_00000000000000", "type": "charge.refunded", "object": "event", "request": null, "data": { "object": { "id": "ch_00000000000000", "object": "charge", "created": 1402433517, "livemode": false, "paid": true, "amount": 1000, "currency": "usd", "refunded": true, "card": { "id": "card_00000000000000", "object": "card", "last4": "0028", "type": "Visa", "exp_month": 8, "exp_year": 2015, "fingerprint": "a5KWlTcrmCYk5DIYa", "country": "US", "name": "First Last", "address_line1": "null", "address_line2": null, "address_city": "null", "address_state": "null", "address_zip": "null", "address_country": "US", "cvc_check": null, "address_line1_check": "fail", "address_zip_check": "pass", "customer": "cus_00000000000000" }, "captured": true, "refunds": [ { "id": "re_104CKt4uGeYuVLAahMwLA2TK", "amount": 100, "currency": "usd", "created": 1402433533, "object": "refund", "charge": "ch_104CKt4uGeYuVLAazSyPqqLV", "balance_transaction": "txn_104CKt4uGeYuVLAaSNZCR867", "metadata": {} }, { "id": "re_104CKt4uGeYuVLAaDIMHoIos", "amount": 200, "currency": "usd", "created": 1402433539, "object": "refund", "charge": "ch_104CKt4uGeYuVLAazSyPqqLV", "balance_transaction": "txn_104CKt4uGeYuVLAaqSwkNKPO", "metadata": {} }, { "id": "re_4CL6n1r91dY5ME", "amount": 700, "currency": "usd", "created": 1402434306, "object": "refund", "charge": "ch_4CL6FNWhGzVuAV", "balance_transaction": "txn_4CL6qa4vwlVaDJ" } ], "balance_transaction": "txn_00000000000000", "failure_message": null, "failure_code": null, "amount_refunded": 1000, "customer": "cus_00000000000000", "invoice": null, "description": "this is a description", "dispute": null, "metadata": {}, "statement_description": "this is a description", "fee": 0 } } }

  • Call load using a div id that has been passed into a function, div id is a parameter

    - by tittatty
    I am dynamically creating divs within a jquery accordion that are loaded with data as when the user clicks on the accordion title. I have this all working except that when I pass the div id into the load details method, the call to .load() does not work. What can I do to fix this? It seems like a simple javascript string eval would work but I can not find what I am looking for. Code: Here is the basic function: function loadDetails(div_id) { var load_string = "ajax/get_details.aspx"; $(div_id).load(load_string); } This function is called correctly on the click event and the div_id is passed in correctly but the load function is not working. If I use code like this it work correctly: $('#test').load(load_string);

  • .net Attributes that handle exceptions - usage on a property accessor

    - by Mr AH
    Hi, well I know from my asp.net mvc experience that you can have attributes that handle exceptions (HandleErrorAttribute). As far as I can tell the Controller class has some OnException event which may be integral to this behaviour. However, I want to do something similar in my own code: dream example: public String MyProperty { [ExceptionBehaviour(typeof(FormatException), MyExEnum.ClearValue)] set { _thing.prop = Convert.ToThing(value); } } .... The code above obviously makes very little sense, but is close to the kind of thing I wish to do. I want the attribute on the property set accessor to catch some type of exception and then deal with this in some custom way (or even just swallow it). Any ideas guys?

  • Bind jQuery UI autocomplete using .live()

    - by seth.vargo
    I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

  • Dependent checkbox, do you think this can be simplified more?

    - by Louie Miranda
    I have the following code which is working, I was wondering if this can simplified more. Demo: http://jsfiddle.net/TnpNV/8/ <form name="cbform"> <input type="checkbox" value="1" name="one" id="one" /> one<br /> <input type="checkbox" value="1" name="two" id="two" /> two </form>? <script> $('#one, #two').click(function(event) { var checked = $(this).is(':checked'); if (checked) { $('#one').attr('checked', true); $('#two').attr('checked', true); } else { $('#one').attr('checked', false); $('#two').attr('checked', false); } }); </script> It's basically a two checkbox that is dependent on each other. Jquery was used to check and uncheck them. Regards

  • Global variables that can be used in multiple jQuery functions

    - by YouBook
    Can you be able to contain variables that can be used in multiple functions in jQuery, example: var self = $(this); var box = self.parents('.box'); $('#title').click(function() { self.css('background', 'red'); box.slideDown('slow'); }).dblclick(function() { self.css('background', 'green'); box.slideUp('slow'); }); So that self and box can be used within these event functions so I don't have to keep doing this: $('#title').click(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'red'); }).dblclick(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'green'); }); But question is, is it possible, if so, how can you do that?

  • Is there a convention for organizing the include/exports in a large C++ project ?

    - by BlueTrin
    Hello, In a large C++ solution, is there a best/standard way to separate the include files necessary to build an intermediary DLL and the include files which will be used by the DLL clients ? We have grouped all the include files in a folder called Interface (for DLL interface), but there the customers have to either include the Interface folder as a default include folder or type the full name as: #include "ProjectName/Interface/myinterface.h" Wouldn't it be better to create a separate folder called exports where I would create a folder called ProjectName and put the include files there ? So that the customers would be typing: #include "ProjectName/myinterface.h" If I do the thing right above, then should I keep the files within the solution and produce a post build event (I use Visual Studio 2k5) to copy the files into the "export" folder (/ProjectName/) ? Or is it better to just include directly the files from this folder within my project (this is more direct and has less chances to cause maintenance issues ? I am more looking for advice than for a definite solution. Thank you for reading this ! Anthony

  • Java/Swing: Problem with key listener

    - by Mike
    I have a search dialog with a JTextField that's being used as a search box. When the user types something, it searches the DB, shows the result in a JTable and selects the first item in it. If the first result is what they were looking for, I want to let them quickly accept the dialog, by pressing Enter (while the JTextField is focused). So I added a KeyListener to the JTextField and it's working OK. Now the problem: The user opens can open the dialog by pressing Enter when a "Search" button on the dialog's parent frame is focused. The dialog is displayed and the JTextField gets the keyReleased event (from the Enter key that displayed it), so it shows up and closes. If the user holds Enter down, then the JTextField receives the keyPressed, keyTyped and keyReleased events. How can I fix without resorting to ugly workarounds? Platform is Windows 7 x64, btw. Test NetBeans project here: http://dl.dropbox.com/u/6354360/KeyListenerTest.zip Thanks.

  • Good open source analytics/stats software in PHP?

    - by makeee
    The url shortening service I'm building needs to display some basic click stats to users: # of clicks, conversions, referring domains, and country (filterable by a date range). I'll possibly want more advanced stats in the future. Is there existing open source software that will allow me to pass events to it and then easily display a bar or line graph of that event (for example, a line graph of "conversions" between two specified dates). It seems like something like this should exist and would be much easier then building the whole thing from scratch. I know there are graphing scripts, but that still requires me to format the data (usually as an xml file) and then pass it to the graph. I'm looking for something a bit more complete, which I can just feed the events and then it does everything else.
