  • Multiple HTML lines with jquery tooltip plugin

    - by dafi
    I'm using the plugin http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/ to create tooltips with JQuery but I can't created tooltips containing 3 (or more) lines of HTML code. I need to render as tooltip the content shown below (obviously the content is generated dynamically an this it only a proof of concept) <p>Line1</p> <p>Line2 <span style="...">blah blah</span></p> <p>Line3</p> The showBody property seems applicable only to title attributes. Found the problem Apparently jquery.html("...") requires a root tag otherwise generates an empty string. My original code was bodyHandler: function() { return $("<span id='caption'>line1</span>" + "<span id='tags'>line2</span>"); } need to be written with a dummy root tag removed by JQuery bodyHandler: function() { return $( "<root-dummy-tag>" + "<span id='caption'>line1</span>" + "<span id='tags'>line2</span>" + "</root-dummy-tag>" ); }

  • How can I control the action of onbeforeunload in IE?

    - by SpawnCxy
    Hi all I've got a problem about onbeforeunload recently that I need to pop up a voting page if the user try closes their IE browser.And I did it by using <body onbeforeunload="makevote()"> And the main structure of makevote() in javascript as follows: function makevote() { comet.distruct(); if(csid != null && isvote == null) { window.event.returnValue = false window.event.returnValue='press “cancel” to vote please!' showComDiv(popvote,"popiframe",400,120,'your vote here','dovote()'); } } For last three months this voting function performed so ugly that I got only less than 8,000 votes from more than 4,50,000 vistors.I think the problem is, when the users try to close their browsers,the onbeforeunload property pops up a comfirm box which covered my voting box while most users click the OK button,which means close comfirming is done,as a habit.So my question is how can I control the comfirming box made by onbeforeunload myself? So far I can only define the message it shows.For example if I click the "OK" ,I'll go to the voting box instead of closing my IE.And if there's any other better way to do this?Help would be greatly appreciated! Regards

  • using JQuery and Prototype in the same page

    - by Don
    Hi, Several of my pages use both JQuery and Protoype. Since I upgraded to version 1.3 of JQuery this appears to be causing problems, because both libraries define a function named '$'. JQuery provides a function noConflict() which relinquishes control of $ to other libraries that may be using it. So it seems like I need to go through all my pages that look like this: <head> <script type="text/javascript" src="/obp/js/prototype.js"></script> <script type="text/javascript" src="/obp/js/jquery.js"></script> </head> and change them to look like this: <head> <script type="text/javascript" src="/obp/js/prototype.js"></script> <script type="text/javascript" src="/obp/js/jquery.js"></script> <script type="text/javascript"> jQuery.noConflict(); var $j = jQuery; </script> </head> I should then be able to use '$' for Prototype and '$j' (or 'jQuery') for JQuery. I'm not entirely happy about duplicating these 2 lines of code in every relevant page, and expect that at some point somebody is likely to forget to add them to a new page. I'd prefer to be able to do the following Create a file jquery-noconflict.js which "includes" jquery.js and the 2 lines of code shown above Import jquery-noconflict.js (instead of jquery.js) in all my JSP/HTML pages However, I'm not sure if it's possible to include one JS file in another, in the manner I've described? Of course an alternate solution is simply to add the 2 lines of code above to jquery.js directly, but if I do that I'll need to remember to do it every time I upgrade JQuery. Thanks in advance, Don

  • Why won't this DOM element disappear?

    - by George Edison
    I have a page that uses jQuery with a small glitch. I managed to get this down to a simple example that demonstrates the problem: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function hideIt() { $('#hideme').fadeOut('slow', function() { $(this).remove(); } ); } </script> </head> <body> <div id='#hideme'>Hide me!</div> <button onclick='hideIt();'>Hide</button> </body> </html> As you would expect, the problem is simple: the caption doesn't disappear. What simple thing did I overlook? (Or if it's not a simple thing, what complicated thing did I miss?)

  • jquery click an img hide an LI

    - by Kirby
    i have something similar to the following... used a python script to JSON to populate. <ul> <li id="p1" class="x">val1 <img id="ip1" class="redx" src="redx.gif"/></li> <li id="p2" class="x">val2 <img id="ip2" class="redx" src="redx.gif"/></li> <li id="p3" class="x">val3 <img id="ip3" class="redx" src="redx.gif"/></li> <li id="p4" class="x">val4 <img id="ip4" class="redx" src="redx.gif"/></li> </ul> I'd like some jquery to... when click the red x image.. to hide the whole LI cell it is in. I have tried a few things but ... to no avail. EDIT: All in all.. this doesnt seem to trigger ... this seems like a fundamental issue. $(function(){ function removeli() { alert("got here" + this.id); } $("redx").click(removeli); }); Any ideas on the final jquery code to accomplish this?

  • HttpWebRequest Timeouts After Ten Consecutive Requests

    - by Bob Mc
    I'm writing a web crawler for a specific site. The application is a VB.Net Windows Forms application that is not using multiple threads - each web request is consecutive. However, after ten successful page retrievals every successive request times out. I have reviewed the similar questions already posted here on SO, and have implemented the recommended techniques into my GetPage routine, shown below: Public Function GetPage(ByVal url As String) As String Dim result As String = String.Empty Dim uri As New Uri(url) Dim sp As ServicePoint = ServicePointManager.FindServicePoint(uri) sp.ConnectionLimit = 100 Dim request As HttpWebRequest = WebRequest.Create(uri) request.KeepAlive = False request.Timeout = 15000 Try Using response As HttpWebResponse = DirectCast(request.GetResponse, HttpWebResponse) Using dataStream As Stream = response.GetResponseStream() Using reader As New StreamReader(dataStream) If response.StatusCode <> HttpStatusCode.OK Then Throw New Exception("Got response status code: " + response.StatusCode) End If result = reader.ReadToEnd() End Using End Using response.Close() End Using Catch ex As Exception Dim msg As String = "Error reading page """ & url & """. " & ex.Message Logger.LogMessage(msg, LogOutputLevel.Diagnostics) End Try Return result End Function Have I missed something? Am I not closing or disposing of an object that should be? It seems strange that it always happens after ten consecutive requests. Notes: In the constructor for the class in which this method resides I have the following: ServicePointManager.DefaultConnectionLimit = 100 If I set KeepAlive to true, the timeouts begin after five requests. All the requests are for pages in the same domain. EDIT I added a delay between each web request of between two and seven seconds so that I do not appear to be "hammering" the site or attempting a DOS attack. However, the problem still occurs.

  • Academic question: typename

    - by Arman
    Hi, recently I accounted with a "simple problem" of porting code from VC++ to gcc/intel. The code is compiles w/o error on VC++: #include <vector> using std::vector; template <class T> void test_vec( std::vector<T> &vec) { typedef std::vector<T> M; /*==> add here typename*/ M::iterator ib=vec.begin(),ie=vec.end(); }; int main() { vector<double> x(100, 10); test_vec<double>(x); return 0; } then with g++ we have some unclear errors: g++ t.cpp t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&)': t.cpp:13: error: expected `;' before 'ie' t.cpp: In function 'void test_vec(std::vector<T, std::allocator<_CharT> >&) [with T = double]': t.cpp:18: instantiated from here t.cpp:12: error: dependent-name 'std::M::iterator' is parsed as a non-type, but instantiation yields a type t.cpp:12: note: say 'typename std::M::iterator' if a type is meant If we add typename before iterator the code will compile w/o pb. If it is possible to make a compiler which can understand the code written in the more "natural way", then for me is unclear why we should add typename? Which rules of "C++ standards"(if there are some) will be broken if we allow all compilers to use without "typename"? kind regards Arman.

  • How to run validator from javascript?

    - by David Shochet
    Here is a part of my code: <asp:ListBox ID="lbRD" runat="server" DataSourceID="RDSqlDataSource" onchange="JSFillDetail();" DataTextField="????????" DataValueField="ID" Width="188px" Height="200px"/> <asp:TextBox ID="txtDescription" runat="server" /> <asp:RequiredFieldValidator ID="txtDescriptionRequiredFieldValidator" runat="server" ErrorMessage="???????? ???????? ???????????? ??? ??????????" ControlToValidate="txtDescription" /> I have a listbox, a textbox and a required field validator on my page. When the user selects something from the listbox, the selected item appears in the textbox using a javascript function. When the page is submitted, the validator reports an error in case the textbox is empty. If after that the user selects something from the listbox, the error message is still displayed, even though the textbox is not empty anymore. How can I make the validator validate the textbox, or even better, to clear the error message from the javascript function that fills the textbox? Thanks, David

  • GLOBAL loading inside each single button with Jquery in ajax calls of asp.net mvc

    - by Ricky
    I have the following scenario: I have a button\link with a image inside like this: <button type="submit" id="myButton" class="button"><img src="../../Content/images/check.png" id="defaultImage" /> SaveData!!!</button> We are OK here! Now what I need to do is: I want on the click that the image change for a loading element that is previously loaded in the page like this: <img id="loadingImage" src="../../Content/images/loader.gif" style="display: none;" alt="loading"/> And then when the load complete turn back the old button image, I ended with this code: function loader() { var $button = $('#myButton'); if (btnState == '1') { $button.find('img').hide(); $button.prepend($('#loadingImage')); $('#loadingImage').css({ 'display': 'inherit' }); btnState = '0'; } else { $button.find('img').hide(); $button.prepend($('#defaultImage')); $('#defaultImage').show(); btnState = '1'; } } This does the trick for ONE SINGLE button(since I pass its ID in the function) but, when I have for example a grid with a button on each line, I found inviable when managing a screen with many buttons do this for each of then. The main question is: How can I make this method general for all buttons/links on one specific class in the page? The goal is: Click a button, get the image and change it and stop(can be manual). I just don't wanna have to Hook ALL buttons.

  • Google Chrome Extension - Help needed

    - by Jim-Y
    Im new on Google Chrome Extensions coding, and i have some basic questions. I want to make a Chrome Extension, and the scheme is the following: -a popup window, containing buttons and result fields (popup.html) -when a button is clicked, i want to trigger an event, this event should connect to a webserver (i make the servlet too), and gather information from the server. (XMLHttpRequest()) -after that, i want my extension to load the gathered information into one of the result fields. Simple, isn't it? But i have several problems, right at the beginning:( I started developing with reading tutorials, but i have fog on the main structure of an extension. Now, i started an app, containing a popup.html, manifest.json ... In popup.html theres a result field, and a button <div id="extension_container"> <div id="header"> <p id="intro">Result here</p> <button type="button" id="button">Click Me!</button> </div> <!-- END header --> <div id="content"> </div> <!-- END content --> When button is clicked, i trigger an event, handeled with jquery, code here: <script> $(document).ready(function(){ $("#button").click(function(){ $("#intro").text("Hello, im added"); alert("Clicked"); }); }); </script> And here comes the problem, in popup.html this doesnt work, if i load it to Chrome, nothing happens. Otherwise, if i open popup.html in browser, not as an extension, everything works fine. So, i think i have basic misunderstandings on extension structures, starting with background pages, background javascript and so on.. :( Could anyone help me?

  • In ParallelPython, a method of an object ( object.func() ) fails to manipulate a variable of an object ( object.value )

    - by mehmet.ali.anil
    With parallelpython, I am trying to convert my old serial code to parallel, which heavily relies on objects that have methods that change that object's variables. A stripped example in which I omit the syntax in favor of simplicity: class Network: self.adjacency_matrix = [ ... ] self.state = [ ... ] self.equilibria = [ ... ] ... def populate_equilibria(self): # this function takes every possible value that self.state can be in # runs the boolean dynamical system # and writes an integer within self.equilibria for each self.state # doesn't return anything I call this method as: Code: j1 = jobserver.submit(net2.populate_equilibria,(),(),("numpy as num")) The job is sumbitted, and I know that a long computation takes place, so I speculate that my code is ran. The problem is, i am new to parallelpython , I was expecting that, when the method is called, the variable net2.equilibria would be written accordingly, and I would get a revised object (net2) . That is how my code works, independent objects with methods that act upon the object's variables. Rather, though the computation is apparent, and reasonably timed, the variable net2.equilibria remains unchanged. As if PP only takes the function and the object, computes it elsewhere, but never returns the object, so I am left with the old one. What do I miss? Thanks in advance.

  • JQuery Cycle fails on Page Refresh

    - by Darknight
    In a similar issue as this one: http://stackoverflow.com/questions/1719475/jquery-cycle-firefox-squishing-images I've managed to overcome the initial problem using Jeffs answer in the above link. However now I have noticed a new bug, upon page refresh it simply does not work. I have tried a hard refresh (ctrl+F5) but this does not work. However when you come page to the page it loads fine. here is my modified version (taken from Jeff's): <script type="text/javascript"> $(document).ready(function() { var imagesRemaining = $('#slideshow img').length; $('#slideshow img').bind('load', function(e) { imagesRemaining = imagesRemaining - 1; if (imagesRemaining == 0) { $('#slideshow').show(); $('#slideshow').cycle({ fx: 'shuffle', speed: 1200 }); } }); }); </script> Any ideas? I've also tried JQuery Live but could not implement it correctly. I've also tried Meta tags to force images to load. But it only works first time round.

  • Flash gets XML but the values are wrong, as3

    - by VideoDnd
    Flash receives the XML, but the values are wrong. How do I fix this? Problem I can see the XML loaded with no errors, but my output is way off. It's as though it's not receiving any values. Numbers in the output window and animation move rapidly. The Flash file runs as if it's variables where set to zero. I changed the order of my code, but that didn't help with this. Please explain how I can correct this. SWF //load xml var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("xml.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); //parse XML function processXML(e:Event):void { myXML = new XML(e.target.data); trace(myXML); //receive values from XML delay = parseInt(myXML.DELAY.text()); trace(delay); repeat = parseInt(myXML.REPEAT.text()); trace(repeat); } //variables var delay:uint = 0; var repeat:uint = 0; //timer and event var timer:Timer = new Timer(uint(delay),uint(repeat)); timer.addEventListener(TimerEvent.TIMER, countdown); //counter function countdown(event:TimerEvent) { myText.text = String(0 + timer.currentCount); trace(0 + timer.currentCount); } timer.start(); XML <?xml version="1.0" encoding="utf-8"?> <SESSION> <DELAY TITLE="starting position">1000</DELAY> <REPEAT TITLE="starting position">60</REPEAT> </SESSION>

  • Using jQuery to parse an RSS feed, having trouble in firefox and chrome.

    - by sjmarshy
    I used a jQuery library called jFeed to parse and display my blogs rss feed on my personal website. It worked perfectly well at first, but upon checking later it simply displays nothing, except in Internet Explorer, where it seems to work fine. After checking the javascript console using Firebug in Firefox, it shows an error in the 'XML' tab as follows: XML Parsing Error: no element found Location: moz-nullprincipal:{3f8a0c62-32b4-4f63-b69c- 9ef402b40b64} Line Number 1, Column 1: ^ Though I have no idea what to do with this information. Here is the code I used to get the rss feed and display it (it is almost exactly the same as the example provided by the jFeed website): jQuery.getFeed({ url: 'http://sammarshalldesign.co.uk/blog/wordpress/?feed=rss2', success: function(feed) { var html = ''; for(var i = 0; i < feed.items.length && i < 5; i++) { var item = feed.items[i]; html += '<h3>' + '<a href="' + item.link + '">' + item.title + '</a>' + '</h3>'; html += '<div>' + item.description + '</div>'; }//end for jQuery('#feed').append(html); }//end feed function });//end getfeed Any help would be really appreciated.

  • Font not showing bullet points

    I have embedded my font using the embed meta tag, along which the entire range of Unicode characters... here is my CustomTextField class: [Embed(source='../assets/fonts/Arial.ttf',fontName='CustomFont',fontWeight='regular', unicodeRange='U+0020-U+0040,U+0041-U+005A,U+005B-U+0060,U+0061-U+007A,U+007B-U+007E,U+0080-U+00FF,U+0100-U+017F,U+0400-U+04FF,U+0370-U+03FF,U+1E00-U+1EFF', mimeType='application/x-font-truetype' )] public static var MY_FONT:Class; [Embed(source='../assets/fonts/Arial Bold.ttf',fontName='CustomFont',fontWeight='bold', unicodeRange='U+0020-U+0040,U+0041-U+005A,U+005B-U+0060,U+0061-U+007A,U+007B-U+007E,U+0080-U+00FF,U+0100-U+017F,U+0400-U+04FF,U+0370-U+03FF,U+1E00-U+1EFF', mimeType='application/x-font-truetype' )] public static var MY_FONT_BOLD:Class; public static const DEFAULT_FONT:String = "CustomFont"; public static const DEFAULT_TEXT_COLOUR:int = 0x000000; public static const DEFAULT_TEXT_SIZE:int = 14; private var _tf:TextFormat = new TextFormat(DEFAULT_FONT, DEFAULT_TEXT_SIZE, DEFAULT_TEXT_COLOUR); public function CustomTextField():void { Font.registerFont(CustomTextField.MY_FONT); Font.registerFont(CustomTextField.MY_FONT_BOLD); _tf.size = 16; antiAliasType = AntiAliasType.ADVANCED; sharpness = 0; defaultTextFormat = _tf; autoSize = TextFieldAutoSize.LEFT; embedFonts = true; } public override function set htmlText(value:String):void { super.htmlText = value; setTextFormat(_tf); } For some reason, using tags intends the text perfectly, but I am not seeing any bullet points. The font is just standard Arial, so it isn't a case of the font missing the bullet character. Does anyone have any idea as to why Flex is not showing the bullet point characters?

  • 'echo' or drop out of 'programming' write HTML then start PHP code again

    - by thecoshman
    For the most part, when I want to display some HTML code to be actually rendered I would use a 'close PHP' tag, write the HTML, then open the PHP again. eg <?php // some php code ?> <p>HTML that I want displayed</p> <?php // more php code ?> But I have seen lots of people who would just use echo instead, so they would have done the above something like <?php // some php code echo("<p>HTML that I want displayed</p>"); // more php code ?> Is their any performance hit for dropping out and back in like that? I would assume not as the PHP engine would have to process the entire file either way. What about when you use the echo function in the way that dose not look like a function, eg echo "<p>HTML that I want displayed</p>" I would hope that this is purely a matter of taste, but I would like to know if I was missing out on something. I personally find the first way preferable (dropping out of PHP then back in) as it helps draw a clear distinction between PHP and HTML and also lets you make use of code highlighting and hinting for your HTML, which is always handy.

  • Setting Parameters from another Parameter In SSRS

    - by Mike
    I was able to get this working is SSRS 2008, but do to the fact that my company only has 2005 servers I need to downgrade the report to 2005. The idea is for a given person name there are two key fields EntityType and EntityId So I have a parameter from a dataset where the Label is the Name and the value is EntityType_EntityId I use the split function to take the left and right sides of from _ In 2008, I set the query parameters of the dataset to the split function and it works In 2005, I set the Default Value of each Report Parameters Now when I run the report and put textboxes showing the value of the parameters, the values are shown correctly but the query does not run. I am guessing that this is a lifecycle issue being Get Name Parameter Run Report THEN Set Parameters = Split of Name But the problem with that is the second time I run the report I should get result and I do not. Does anyone know what I am doing wrong. I guess I can pass in the underscore delimted string to the stored procedure and parse it there, but my question is can this be done in the report? Reason being other callers will pass in the parameters as two seperate values.

  • Prototype's Ajax.Updater not actually updating on IE7.

    - by Ben S
    I am trying to submit a form using Ajax.Updater and have the result of that update a div element in my page. Everything works great in IE6, FF3, Chrome and Opera. However, In IE7 it sporadically works, but more often than not, it just doesn't seem to do anything. Here's the javascript: function testcaseHistoryUpdate(testcase, form) { document.body.style.cursor = 'wait'; var param = Form.serialize(form); new Ajax.Updater("content", "results/testcaseHistory/" + testcase, { onComplete: function(transport) {document.body.style.cursor = 'auto'}, parameters: param, method: 'post' } ); } I've verified using alert() calls that param is set to what I expect. I've read in many places that IE7 caches aggressively and that it might be the root cause, however every after adding the following to my php response, it still doesn't work. header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); To further try to fix a caching issue I've tried adding a bogus parameter which just gets filled with a random value to have different parameters for every call, but that didn't help. I've also found this, where UTF-8 seemed to be causing an issue with IE7, but my page is clearly marked: <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> Does anyone have any idea what could be wrong with IE7 as opposed to the other browsers I tested to cause this kind of issue?

  • Capture *all* display-characters in JavaScript?

    - by Jean-Charles
    I was given an unusual request recently that I'm having the most difficult time addressing that involves capturing all display-characters when typed into a text box. The set up is as follows: I have a text box that has a maxlength of 10 characters. When the user attempts to type more than 10 characters, I need to notify the user that they're typing beyond the character count limit. The simplest solution would be to specify a maxlength of 11, test the length on every keyup, and truncate back down to 10 characters but this solution seems a bit kludgy. What I'd prefer to do is capture the character before keyup and, depending on whether or not it is a display-character, present the notification to the user and prevent the default action. A white-list would be challenging since we handle a lot of international data. I've played around with every combination of keydown, keypress, and keyup, reading event.keyCode, event.charCode, and event.which, but I can't find a single combination that works across all browsers. The best I could manage is the following that works properly in =IE6, Chrome5, FF3.6, but fails in Opera: NOTE: The following code utilizes jQuery. $(function(){ $('#textbox').keypress(function(e){ var $this = $(this); var key = ('undefined'==typeof e.which?e.keyCode:e.which); if ($this.val().length==($this.attr('maxlength')||10)) { switch(key){ case 13: //return case 9: //tab case 27: //escape case 8: //backspace case 0: //other non-alphanumeric break; default: alert('no - '+e.charCode+' - '+e.which+' - '+e.keyCode); return false; }; } }); }); I'll grant that what I'm doing is likely over-engineering the solution but now that I'm invested in it, I'd like to know of a solution. Thanks for your help!

  • AS3: Array of objects parsed from XML remains with zero length

    - by Joel Alejandro
    I'm trying to parse an XML file and create an object array from its data. The data is converted to MediaAlbum classes (class of my own). The XML is parsed correctly and the object is loaded, but when I instantiate it, the Albums array is of zero length, even when the data is loaded correctly.

  • manipulating textbox value

    - by chameios
    hello All, I am new to the programming world of dojo and web applications. I am trying to acomplish a task where I want to manipulate the textbox value with some text. I tried everything including some code from dojocampus, but even this code doesnot do anything. I have also tried to create an instance , with dojo.widget.byId and dijit.byId and then tried the instance.value = 'newtext' and everything that I could find but for some reason , the textbox is not updating. Please help me. <html> <head> <title>Dojo example</title> <style type="text/css"> @import "pathtodojo/dijit/themes/nihilo/nihilo.css"; </style> <style type="text/css"> </style> <script type="text/javascript" src="pathtodojo/dojo/dojo.js" djConfig="parseOnLoad:true, isDebug: true"></script> <script> dojo.require("dijit.form.TextBox"); function init() { var box0 = dijit.byId("value0Box"); var box1 = dijit.byId("value1Box"); box1.attr("value", box0.attr("value") + " modified"); dojo.connect(box0, "onChange", function(){ box1.attr("value", box0.attr("value") + " modified"); }); } dojo.addOnLoad(init); </script> <body class="nihilo"> A textbox with a value: <input id="value0Box" dojoType="dijit.form.TextBox" value="Some value" intermediateChanges="true"></input> <br> A textbox set with a value from the above textbox: <input id="value1Box" dojoType="dijit.form.TextBox"></input> <br> </body> </html> regards C

  • Trace PRISM / CAL events (best practice?)

    - by Christian
    Ok, this question is for people with either a deep knowledge of PRISM or some magic skills I just lack (yet). The Background is simple: Prism allows the declaration of events to which the user can subscribe or publish. In code this looks like this: _eventAggregator.GetEvent<LayoutChangedEvent>().Subscribe(UpdateUi, true); _eventAggregator.GetEvent<LayoutChangedEvent>().Publish("Some argument"); Now this is nice, especially because these events are strongly typed, and the declaration is a piece of cake: public class LayoutChangedEvent : CompositePresentationEvent<string> { } But now comes the hard part: I want to trace events in some way. I had the idea to subscribe using a lambda expression calling a simple log message. Worked perfectly in WPF, but in Silverlight there is some method access error (took me some time to figure out the reason).. If you want to see for yourself, try this in Silverlight: eA.GetEvent<VideoStartedEvent>().Subscribe(obj => TraceEvent(obj, "vSe", log)); If this would be possible, I would be happy, because I could easily trace all events using a single line to subscribe. But it does not... The alternative approach is writing a different functions for each event, and assign this function to the events. Why different functions? Well, I need to know WHICH event was published. If I use the same function for two different events I only get the payload as argument. I have now way to figure out which event caused the tracing message. I tried: using Reflection to get the causing event (not working) using a constructor in the event to enable each event to trace itself (not allowed) Any other ideas? Chris PS: Writing this text took me most likely longer than writing 20 functions for my 20 events, but I refuse to give up :-) I just had the idea to use postsharp, that would most likely work (although I am not sure, perhaps I end up having only information about the base class).. Tricky and so unimportant topic...

  • Why does my data not pass into my view correctly?

    - by dmanexe
    I have a model, view and controller not interacting correctly, and I do not know where the error lies. First, the controller. According to the Code Igniter documentation, I'm passing variables correctly here. function view() { $html_head = array( 'title' => 'Estimate Management' ); $estimates = $this->Estimatemodel->get_estimates(); $this->load->view('html_head', $html_head); $this->load->view('estimates/view', $estimates); $this->load->view('html_foot'); } The model (short and sweet): function get_estimates() { $query = $this->db->get('estimates')->result(); return $query; } And finally the view, just to print the data for initial development purposes: <? print_r($estimates); ?> Now it's undefined when I navigate to this page. However, I know that $query is defined, because it works when I run the model code directly in the view.
