  • (JQuery) How to call a custom function before following link

    - by morpheous
    I want to achieve the following behavior in a page link. When the link is clicked, I want to: First, send (POST) some data back to the server Second, allow the browser to navigate to the url that the link was pointing to. I am relatively new to JQuery, and here is my first attempt below. I will be grateful to any jQuery gurus in here to fillin the blanks (and maybe point out how the snippet below may be improved). <html> <head>test page</head> <body> <div><a id="hotlink" href="http://www.example.com">Clik and see</a></div> </body> <script type="text/javascript"> $(document).ready(function(){ $('hotlink').click(function(){ //AJAX Post data here ... //follow the link url (i.e. navigate/browse to the link) ... }); }); </script> </html>

  • android service using SystemClock.elapsedRealTime() instead of SystemClock.uptimeMillis() works in emulator but not in samsung captivate ?

    - by Aleadam
    First question here in stackoverflow :) I'm running a little android 2.2 app to log cpu frequency usage. It is set up as a service that will write the data every 10 seconds using a new thread. The code for that part is very basic (see below). It works fine, except that it would not keep track of time while the phone is asleep (which, I know, is the expected behavior). Thus, I changed the code to use SystemClock.elapsedRealTime() instead. Problem is, in emulator both commands are equivalent, but in the phone the app will start the thread but it will never execute the mHandler.postAtTime command. Any advice regarding why this is happening or how to overcome the issue is greatly appreciated. PS: stopLog() is not being called. That's not the problem. mUpdateTimeTask = new Runnable() { public void run() { long millis = SystemClock.uptimeMillis() - mStartTime; int seconds = (int) (millis / 1000); int minutes = seconds / 60; seconds = seconds % 60; String freq = readCPU (); if (freq == null) Toast.makeText(CPU_log_Service.this, "CPU frequency is unreadable.\nPlease make sure the file has read rights.", Toast.LENGTH_LONG).show(); String str = new String ((minutes*60 + seconds) + ", " + freq + "\n"); if (!writeLog (str)) stopLog(); mHandler.postAtTime(this, mStartTime + (((minutes * 60) + seconds + 10) * 1000)); }}; mStartTime = SystemClock.uptimeMillis(); mHandler.removeCallbacks(mUpdateTimeTask); mHandler.postDelayed(mUpdateTimeTask, 100);

  • Writing all the html of a document with jquery instead of in the page body?

    - by Robert
    I'm a UI person currently working on a web application, where most of the people I work with are back end developers. I'm currently at a disagreement with them about whether or not the above is a prudent thing to do. This application doe use quite a bit of JavaScript, and wouldn't even work without it unfortunately. This being the case, One of the back end developers that I'm working with is claiming that pages could and even SHOULD be build completely with JavaScript or jquery. This caught me completely off guard. We're talking about div tags, lists, background images and text here. I'm trying to explain to him that this isn't the right way to do things at all, and from a best practices perspective: content(html) should be separate from presentation(css), and behavior(script etc.). I know that it's possible to write html in jquery, although I haven't done it, but am I wrong in my thinking that this isn't the way things should be done. Is it even possible to write ALL the code with jquery? would love to hear any thoughts either way, as I will be discussing this with him again tomorrow.

  • Unnecessary Redundancy with Tables.

    - by Stacey
    My items are listed as follows; This is just a summary of course. But I'm using a method shown for the "Detail" table to represent a type of 'inheritence', so to speak - since "Item" and "Downloadable" are going to be identical except that each will have a few additional fields relevant only to them. My question is in this design pattern. This sort of thing appears many, many times in our projects - is there a more intelligent way to handle it? I basically need to normalize the tables as much as possible. I'm extremely new to databases and so this is all very confusing to me. There are 5 items. Awards, Items, Purchases, Tokens, and Downloads. They are all very, very similar, except each has a few pieces of data relevant only to itself. I've tried to use a declaration field (like an enumerator 'Type' field) in conjunction with nullable columns, but I was told that is a bad approach. What I have done is take everything similar and place it in a single table, and then each type has its own table that references a column in the 'base' table. The problem occurs with relationships, or junctions. Linking all of these back to a customer. Each type takes around 2 additional tables to properly junction all of the data together- and as such, my database is growing very, very large. Is there a smarter practice for this kind of behavior? Item ID | GUID Name | varchar(64) Product ID | GUID Name | varchar(64) Store | GUID [ FK ] Details | GUID [FK] Downloadable ID | GUID Name | varchar(64) Url | nvarchar(2048) Details | GUID [FK] Details ID | GUID Price | decimal Description | text Peripherals [ JUNCTION ] ID | GUID Detail | GUID [FK] Store ID | GUID Addresses | GUID Addresses ID | GUID Name | nvarchar(64) State | int [FK] ZipCode | int Address | nvarchar(64) State ID | int Name | varchar(32)

  • Perl Linux::Inotify2 - can't respond to events anymore

    - by alcy
    I am getting some really weird behavior when using Linux::Inotify2 module for watching a directory for any newly created files. I had made a test script to see how it worked, and once that was done, I went on to incorporating its usage in the other scripts, in which it didn't work. Then, when I tried my earlier test script again to find some information, strangely that stopped working as well. It hasn't worked since then. There were no package/distro upgrades during that time. The problem is that it has stopped responding to events. Here's the test script: #!/usr/bin/perl use strict; use warnings; use Linux::Inotify2; my $inotify = new Linux::Inotify2 or die "unable to create new inotify object: $!"; my $dir = "/my/dir"; $inotify->watch($dir, IN_CREATE, sub { my $e = shift; print $e->fullname; }) or die " Can't watch $!"; 1 while $inotify->poll; A strace on the running script kills the script. Otherwise when strace is used when starting the script, then it does seem to read the new events, but there's no response to those events. Any suggestions for debugging this further ?

  • “User Control” uses an incorrect event

    - by Lijo
    Hi, I am using two instances of a user control. But when I click on a button in the user control, both of the instances calls the function corresponding to the first event (AcknowledgeReceipt()) However, when I remove the first user control and clicks on the btnRequestClarification, it calls the correct method (RequestClarification()) Is there a way to correct this behavior? acknowledgeModificationPopupCtrl = (ConfirmationPopup)this.LoadControl("~/ConfirmationPopup.ascx"); plHConfirmationPopup.Controls.Add(acknowledgeModificationPopupCtrl); acknowledgeModificationPopupCtrl.ContinueClick += new EventHandler(AcknowledgeReceipt); RequiredFieldValidator reqFValidatorAcknowledge = (RequiredFieldValidator)acknowledgeModificationPopupCtrl.FindControl("reqValidatorTxt"); reqFValidatorAcknowledge.ValidationGroup = "AcknowledgeReceipt"; acknowledgeModificationPopupCtrl.ValidationGroup = "AcknowledgeReceipt"; btnAcknowledgeReceipt.Attributes.Add("onclick", "validateconfirmPopup('true','xx' ,’yyy','Note' ,'true'); return false;"); requestModificationPopupCtrl = (ConfirmationPopup)this.LoadControl("~/ConfirmationPopup.ascx"); plHConfirmationPopup.Controls.Add(requestModificationPopupCtrl); requestModificationPopupCtrl.ContinueClick += new EventHandler(RequestClarification); RequiredFieldValidator reqFValidator = (RequiredFieldValidator)requestModificationPopupCtrl.FindControl("reqValidatorTxt"); reqFValidator.ValidationGroup = "request"; requestModificationPopupCtrl.ValidationGroup = "request"; btnRequestClarification.Attributes.Add("onclick", "validateconfirmPopup('true',’kkk' ,’lll','ff' ,'true'); return false;"); Thanks Lijo

  • Strangest LINQ to SQL case I have ever seen

    - by kubaw
    OK, so this is the strangest issue in .net programming I have ever seen. It seems that object fields are serialized in .net web services in order of field initialization. It all started with Flex not accepting SOAP response from .net web service. I have found out that it was due to the order of serialized fields was statisfying the order of fields in declared serializable class. It had something to do with generic lists and LINQ to SQL but I can't find out what. This one is really hard to reproduce. Example to get the idea: [Serializable] public class SomeSample { public int A; public int B; public int C; } I was querying some data tables within asmx web service using linq and returning list of SomeSample objects: var r = (from ...... select new SomeSample { A = 1, C = 3 }).ToList(); Now the list was once more iterated and B field was applied some value (ex. 2). However the returned soap envelope contained following excerpt: <A>1</A><C>3</C><B>2</B> Please notice the order of serialization. If I initially initialized all fields: var r = (from ...... select new SomeSample { A = 1, B = 2, C = 3 }).ToList(); object was serialized in correct order. I must add, that in both cases the debugger shows exactly the same content of "r" variable. Am I losing my mind or is this normal behavior? Thanks in advance.

  • Kill process started with System.Diagnostic.Process.Start("FileName")

    - by PedroC88
    Hello; I am trying to create an app that will perform actions on specific times (much like the Windows Task Scheduler). I am currently using Process.Start() to lunch the file (or exe) required by the task. I am initiating a process by calling a file (an .mp3) and the process starts WMP (since it is the default application), so far so good. Now I wan't to kill that process. I know that it is normal behavior for the Process.Start(string, string) to return nothing (null in C#) in this case. So I am asking how can i close WMP when I called it through Process.Start(string, string)?? Edit: Please note that I am not opening WMP directly with Process.Start() and this is the line with which I run the process: VB: Me._procs.Add(Process.Start(Me._procInfo)) C#: this._procs.Add(Process.Start(this._procInfo)) _procInfo is a ProcessStartInfo instance. _procInfo.FileName is "C:\route\myFile.mp3". That is why WMP opens. In any case, all of the Start() methods, except for the instance-one which returns a boolean, return nothing (null in C#), because WMP is not the process that was directly created (please note that WMP is run and the song does play).

  • Retrieving an element by array index in jQuery vs the each() function.

    - by Alex Ciminian
    I was writing a "pluginable" function when I noticed the following behavior (tested in FF 3.5.9 with Firebug 1.5.3). $.fn.computerMove = function () { var board = $(this); var emptySquares = board.find('div.clickable'); var randPosition = Math.floor(Math.random() * emptySquares.length); emptySquares.each(function (index) { if (index === randPosition) { // logs a jQuery object console.log($(this)); } }); target = emptySquares[randPosition]; // logs a non-jQuery object console.log(target); // throws error: attr() not a function for target board.placeMark({'position' : target.attr('id')}); } I noticed the problem when the script threw an error at target.attr('id') (attr not a function). When I checked the log, I noticed that the output (in Firebug) for target was: <div style="width: 97px; height: 97px;" class="square clickable" id="8"></div> If I output $(target), or $(this) from the each() function, I get a nice jQuery object: [ div#8.square ] Now here comes my question: why does this happen, considering that find() seems to return an array of jQuery objects? Why do I have to do $() to target all over again? [div#0.square, div#1.square, div#2.square, div#3.square, div#4.square, div#5.square, div#6.square, div#7.square, div#8.square] Just a curiosity :).

  • How do I make a shrinkable scrollbar?

    - by diadem
    What I want: <div style="overflow:scroll;width:100%;height:50%;"> &nbsp; <div style="height:500px;width:400px;border:solid 3px red;"> </div> </div> <div style="overflow:scroll;width:100%;HEIGHT:50%;"> &nbsp; <div style="height:500px;width:400px;border:solid 3px red;"> </div> </div> Notice how if I shrink the height of the window the scrollbars shrink. This is the functionality I want. The issue: I want to make something similar to the above, only with a fixed height of 100 pixels for the top div. If I do this in practice the bottom scrollbar no longer shrinks as I shrink the page - the system adds an outer scrollbar to manage both sections. I don't want this, I want to retain the behavior seen above. How do I do this?

  • jQuery removeClass(), how it works

    - by centro
    I have images on my page. User can add more images onto the page by clicking a button. New images are added asynchronously. Initially, each image on page use a special class to be used when the image is loaded. After the image is loaded, that class is removed. Each image being loaded has the class imageLoading: <img class="imageLoading" scr="someimage.png"> After those images are loaded, I remove that class (simplified code without details): $('img.imageLoading') .each(function(){ $(this) .load(function(){ $(this) .removeClass('imageloading'); });}); Visually, I see that style is removed. But when I run the query again: $('img.imageLoading') I see via debugging that all images, not just loading ones, are returned, i.e. it works like I didn't remove the class for the images that were already loaded. I had a look into the page source, and I saw that actually in HTML the class was not removed, though removeClass() was called. Is that behavior by design that all visual changes are applied but the class attribute is not removed in HTML code? If so, how it can be workarounded in this case. Or, probably, I missed something.

  • How can I bind the same dependency to many dependents in Ninject?

    - by Mike Bantegui
    Let's I have three interfaces: IFoo, IBar, IBaz. I also have the classes Foo, Bar, and Baz that are the respective implementations. In the implementations, each depends on the interface IContainer. So for the Foo (and similarly for Bar and Baz) the implementation might read: class Foo : IFoo { private readonly IDependency Dependency; public Foo(IDependency dependency) { Dependency = dependency; } public void Execute() { Console.WriteLine("I'm using {0}", Dependency.Name); } } Let's furthermore say I have a class Container which happens to contain instances of the IFoo, IBar and IBaz: class Container : IContainer { private readonly IFoo _Foo; private readonly IBar _Bar; private readonly IBaz _Baz; public Container(IFoo foo, IBar bar, IBaz baz) { _Foo = foo; _Bar = bar; _Baz = baz; } } In this scenario, I would like the implementation class Container to bind against IContainer with the constraint that the IDependency that gets injected into IFoo, IBar, and IBaz be the same for all three. In the manual way, I might implement it as: IDependency dependency = new Dependency(); IFoo foo = new Foo(dependency); IBar bar = new Bar(dependency); IBaz baz = new Baz(dependency); IContainer container = new Container(foo, bar, baz); How can I achieve this within Ninject? Note: I am not asking how to do nested dependencies. My question is how I can guarantee that a given dependency is the same among a collection of objects within a materialized service. To be extremely explicit, I understand that Ninject in it's standard form will generate code that is equivalent to the following: IContainer container = new Container(new Foo(new Dependency()), new Bar(new Dependency()), new Baz(new Dependency())); I would not like that behavior.

  • How to add a checkbox for each row in Rails 3.2 index page?

    - by user938363
    We would like to add a checkbox to each row on Rails index page to flag for the row. This checkbox is not part of the object (no checkbox boolean in database). When the index page shows, a user can check the box to trigger an event for the row in following process: #objects/checkbox_index.html.erb <table> <tr> <th>CheckBox</th> <th>Object Name</th> <th>Object ID</th> </tr> <%= @objects.each do |obj| %> <tr> <td><%= checkbox %></td> <td><%= obj.name %></td> <td><%= obj.id %></td> </tr> <% end %> </table> In controller, the process will be like this: @objects.each do |obj| some_event if obj.checked end There are a couple of questions we don't quite understand: 1. How to declare an array checkbox variable on the form and link it to each row of obj? We have been using `attr_accessor` to declare var for a form. 2. How to retrieve each row on checkbox_index form and pass them back to controller? We are using simple_form for new/edit. Can anyone point me towards any good examples of this sort of behavior, or suggest what we should be thinking about? Many Thanks.

  • Databound Label text displays old data upon save. Re-open record and data is correct?

    - by Mike Hestness
    I have a windows forms application. I have a main form and I have a button on this form to set a "Qualified" date/time stamp. I have a Databound label control that I set the value when the user clicks the button. This date/time stamp is working as far as displaying but when you click the save button it either shows blank or the previous date/time. If you then then close the record and re-open it the new date/time value is displayed so the data is getting to the database it's just not persisting in the dataset as new data?? Not sure why the databinding isn't refreshing the value. I have noticed this behavior even if I use a textbox, same thing if I do it programatically. If I manually type in a value it persists?? Here is the code I'm using in the click event of my button: string result = string.Empty; string jobOrderID = UnitOfWork.MasterDSBS.MJOBO[0].JC_IDNO.ToString(); string timeNow = DateTime.Now.ToString(); //Call Web service to make the update RadServices.Service1 rsWeb = new RadServices.Service1(); result = rsWeb.SetQualifiedDate(timeNow, jobOrderID ); //Changed the qualified label text. _btnQualify.Text = "Qualified"; rlQualifiedDate.Text = timeNow;

  • Having an issue with the "this" modifier...

    - by user344246
    I have this method in City class. It should create a new city based on the object which the method is applied to: public City newCity(string newCityName, int dX, int dY) { City c=new City(this); //based on a constructor : City(City c){} c.CityName=newCityName; c.NoOfNeighborhoods=1; c.NumOfResidents=0; c.CityCenter.Move(dX,dY); return c; } CityCenter is of type "Point" which has two fields - x,y. the Move method in Point class is ment to change the CityCenter location. It looks like this: public void Move(int dX, int dY) { this.X = x + dX; this.Y = y + dY; } What happens is that the new object,c and the existing City object are both changed. I think that "this" modifier works on the existing object too... How can I take advantage of the Move method without causing this behavior? Note: this is a closed API, so I can only add private methods to the project.

  • How can I load a div in rails in response to clicks on another div?

    - by mmr
    I'm very new to Rails (and web) programming, so I'm not even sure what technology I should be looking for for this. I've downloaded and run through the first five chapters of the Rails tutorial, but now have a very simple request. On the left hand side of a web page, I will have a table. If the user clicks on an element in that table, I want to have the right hand side of the page show something new. I already have a page to display the table, viz: <div class="center hero-unit"> <div class="container"> <h2>2012 Yearly Report</h2> <div class="row-fluid"> <div class="span12"> <div class="span4"> <table border="1"> </table> </div> <div class="span6"> <!-- load stuff here based on what someone clicks on in the table --> </div> </div> </div> </div> </div> And I'm using bootstrap layouts to display everything. I just don't understand how to change the contents of the 'span6' div based on user behavior in 'span4'.

  • Wrapping <%= f.check_box %> inside <label>

    - by Ben Scheirman
    I have a list of checkboxes on a form. Due to the way the CSS is structured, the label element is styled directly. This requires me to nest the checkbox inside of the tag. This works in raw HTML, if you click on the label text, the state of the checkbox changes. It doesn't work with the rails <%= f.check_box %> helper, however, because it outputs a hidden input tag first. In summary, <label> <%= f.check_box :foo %> Foo </label> this is the output I want: <label> <input type="checkbox" ... /> <input type="hidden" ... /> Foo </label> ...but this is what rails is giving me: <label> <input type="hidden" ... /> <input type="checkbox" ... /> Foo </label> So the label behavior doesn't actually work :(. Is there any way to get around this?

  • Windows setevent processsing

    - by Waldorf
    I wonder how setevent is handled internally within Windows. I have the following situation Std::thread thread loop which executes while std::atomic == true Inside the loop is a waitforsingleObject which sleeps infinite in alertable state. A function stopThread() which does the following: - Clears the atomic bool - Calls Setevent on the event object - Calls thread.join This often hangs, I get the impression that setevent has still some work to do in the current thread, while join blocks the current thread. If I add an additional Boolean in the thread which is set after waitforsinlgleObject and I wait for this to be set before calling join() Everything seems to work ok. Code (error checking omitted here) Init code/declarations: HANDLE m_WakeupThreadEvent; std::atomic<bool> m_ReceiverEnabled; m_WakeupThreadEvent = CreateEvent(NULL, false, false, "RxThreadWakeupEvent" ); Thread code: while(m_ReceiverEnabled) { DWORD rslt = WaitForSingleObjectEx(m_WakeupThreadEvent, INFINITE, true); // Here some checking for rslt; } function code: m_ReceiverEnabled = true; SetEvent( m_WakeupThreadEvent ) m_Thread.join() Is there some explanation for this behavior ? I could not find any details about the operation of setEvent()

  • Height:100% is not considered

    - by Ivan90
    Hi guys, I would want to simulate the behavior of a table with div. I have a struct of my layout divide into three columns: div#wrapper { width:800px; float:left; height:100%; margin-top:7px; text-align:center; } div#left { width:167px; float:left; padding-bottom:50px; margin-right:3px; } div#main { width:454px; float:left; } div#right { width:167px; float:left; margin-left:3px; } wrapper is the container of three columns left,main,right div "main" have a variable content so in some case is more long and in other case is very short. When the content vary,div wrapper is adapted and it's ok but left and right columns don't adapt to wrapper. P.S Without doctype there is no problem, infact I set the height of left, main and right to 100% but when I insert transional.dtd , the height of div is not considered. How can resolve this problem? Sorry for my english!!

  • Wildcards in jnlp template file

    - by Andy
    Since the last security changes in Java 7u40, it is required to sign a JNLP file. This can either be done by adding the final JNLP in JNLP-INF/APPLICATION.JNLP, or by providing a template JNLP in JNLP-INF/APPLICATION_TEMPLATE.JNLP in the signed main jar. The first way works well, but we would like to allow to pass a previously unknown number of runtime arguments to our application. Therefore, our APPLICATION_TEMPLATE.JNLP looks like this: <?xml version="1.0" encoding="UTF-8"?> <jnlp codebase="*"> <information> <title>...</title> <vendor>...</vendor> <description>...</description> <offline-allowed /> </information> <security> <all-permissions/> </security> <resources> <java version="1.7+" href="http://java.sun.com/products/autodl/j2se" /> <jar href="launcher/launcher.jar" main="true"/> <property name="jnlp...." value="*" /> <property name="jnlp..." value="*" /> </resources> <application-desc main-class="..."> * </application-desc> </jnlp> The problem is the * inside of the application-desc tag. It is possible to wildcard a fixed number of arguments using multiple argument tags (see code below), but then it is not possible to provide more or less arguments to the application (Java Webstart will no start with an empty argument tag). <application-desc main-class="..."> <argument>*</argument> <argument>*</argument> <argument>*</argument> </application-desc> Does someone can confirm this problem and/or has a solution for passing a previously undefined number of runtime arguments to the Java application? Thanks alot!

  • Rails 3 server won't start in cucumber environment

    Hi I'm trying to start my rails 3 app in the same environment that cucumber uses because this is necessary for a particular test.

  • jQuery load Google Visualization API with AJAX

    - by Curro
    Hello. There is an issue that I cannot solve, I've been looking a lot in the internet but found nothing. I have this JavaScript that is used to do an Ajax request by PHP. When the request is done, it calls a function that uses the Google Visualization API to draw an annotatedtimeline to present the data. The script works great without AJAX, if I do everything inline it works great, but when I try to do it with AJAX it doesn't work!!! The error that I get is in the declaration of the "data" DataTable, in the Google Chrome Developer Tools I get a Uncaught TypeError: Cannot read property 'DataTable' of undefined. When the script gets to the error, everything on the page is cleared, it just shows a blank page. So I don't know how to make it work. Please help Thanks in advance $(document).ready(function(){ // Get TIER1Tickets $("#divTendency").addClass("loading"); $.ajax({ type: "POST", url: "getTIER1Tickets.php", data: "", success: function(html){ // Succesful, load visualization API and send data google.load('visualization', '1', {'packages': ['annotatedtimeline']}); google.setOnLoadCallback(drawData(html)); } }); }); function drawData(response){ $("#divTendency").removeClass("loading"); // Data comes from PHP like: <CSV ticket count for each day>*<CSV dates for ticket counts>*<total number of days counted> // So it has to be split first by * then by , var dataArray = response.split("*"); var dataTickets = dataArray[0]; var dataDates = dataArray[1]; var dataCount = dataArray[2]; // The comma separation now splits the ticket counts and the dates var dataTicketArray = dataTickets.split(","); var dataDatesArray = dataDates.split(","); // Visualization data var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'Tickets'); data.addRows(dataCount); var dateSplit = new Array(); for(var i = 0 ; i < dataCount ; i++){ // Separating the data because must be entered as "new Date(YYYY,M,D)" dateSplit = dataDatesArray[i].split("-"); data.setValue(i, 0, new Date(dateSplit[2],dateSplit[1],dateSplit[0])); data.setValue(i, 1, parseInt(dataTicketArray[i])); } var annotatedtimeline = new google.visualization.AnnotatedTimeLine(document.getElementById('divTendency')); annotatedtimeline.draw(data, {displayAnnotations: true}); }

  • How does mysql define DISTINCT() in reference documentation

    - by goran
    EDIT: This question is about finding definitive reference to MySQL syntax on SELECT modifying keywords and functions. /EDIT AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax, but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best EDIT After asking the same question on mysql forums I learned that while parsing the SQL mysql does not care about whitespace between functions and column names (but I am still missing a reference). As it seems you can have whitespace between functions and the parenthesis SELECT LEFT (field1,1), field2... and get mysql to understand it as SELECT LEFT(field,1) Similarly SELECT DISTINCT(field1), field2... seems to get decomposed to SELECT DISTINCT (field1), field2... and then DISTINCT is taken not as some undefined (or undocumented) function, but as SELECT modifying keyword and the parenthesis around field1 are evaluated as if they were part of field expression. It would be great if someone would have a pointer to documentation where it is stated that the whitespace between functions and parenthesis is not significant or to provide links to apropriate MySQL forums, mailing lists where I could raise a question to put this into reference. EDIT I have found a reference to server option IGNORE SPACE. It states that "The IGNORE SPACE SQL mode can be used to modify how the parser treats function names that are whitespace-sensitive", later on it states that recent versions of mysql have reduced this number from 200 to 30. One of the remaining 30 is COUNT for example. With IGNORE SPACE enabled both SELECT COUNT(*) FROM mytable; SELECT COUNT (*) FROM mytable; are legal. So if this is an exception, I am left to conclude that normally functions ignore space by default. If functions ignore space by default then if the context is ambiguous, such as for the first function on a first item of the select expression, then they are not distinguishable from keywords and the error can not be thrown and MySQL must accept them as keywords. Still, my conclusions feel like they have lot of assumptions, I would still be grateful and accept any pointers to see where to follow up on this.

  • ASP.NET MVC Consume JSONResult in Bing Maps API

    - by rockinthesixstring
    I know there are a few topics on this, but I seem to be fumbling my way through with no results. I'm trying to use a controller to return JSON results to my Bin Maps functions. Here's what I have for my controller (yes it is properly returning JSON data. Function Regions() As JsonResult Dim rj As New List(Of RtnJson)() rj.Add(New RtnJson("135 Bow Meadows Drive, Cochrane, Alberta", "desc", "title")) rj.Add(New RtnJson("12 Bowridge Dr NW, Calgary, Alberta, Canada", "desc2", "title2")) Return Json(rj, JsonRequestBehavior.AllowGet) End Function Then in my script I have this, but it's not working. <script type="text/javascript"> var map = null; var centerLat = 51.045 ; var centerLon = -114.05722; var json_object = $.getJSON("<%: Url.Action("Regions", "Events")%>"); function LoadMap() { map = new VEMap('bingMap'); map.LoadMap(new VELatLong(centerLat, centerLon), 10); $.each(json_object, function () { alert(this.address); //this alert is returning "address is undefined" StartGeocoding(this.address, this.title, this.desc); }); } function StartGeocoding(address, title, desc) { map.Find(null, // what address, // where null, // VEFindType (always VEFindType.Businesses) null, // VEShapeLayer (base by default) null, // start index for results (0 by default) null, // max number of results (default is 10) null, // show results?
