  • How can I get a value out of a jQuery object?

    - by Jannis
    I am returning some data (example below) and saving it to a jQuery object (or is this an array and I am confusing the two?) when I log the variable that is the object it has the values I am looking for but how do I access the data inside this object? code $itemPosition = { 'top': $item.offset().top, 'left':$item.offset().left }, console.log($itemPosition); This would log out (the in this case expected) top: 0 & left: 490. But how can I know work with those values? Also, while this it is probably obvious I am still in the early stages of learning jQuery/Javascript rest assured that reference books are on their way, but so far the SO community has been invaluable to my learning, so thanks for reading! J.

  • Error : The Type Initializer of Deamon.Global threw an exception in c#

    - by srk
    I am using the below class file, where some variables are declared to use in the entire application. Now i used that variable [BlockLogOut] in another class file to make the value True. I just put this below line and getting error in it.. "TypeInitializationException" Global.BlockLogOut = True; The wired thing is, it was working fine for many months and i am getting this error now on the above line. Of course i was modifying some other stuffs in the application, but surely not this class file. What would have been the problem ? namespace Daemon { class Global { public static bool BlockLogOut = false; } }

  • Jquery Autocomplete Unable to Empty Input on Internet Explorer

    - by Matias
    Hi, I´ve got a Jquery autocomplete input like the following: $("#cities").autocomplete(regionIDs, { minChars: 2, width: 310, autoFill: true, matchContains: "word", formatItem: function(row) { return row.city + ", " + "<span>" + row.country + "</span>"; }, formatMatch: function(row) { return row.city; }, formatResult: function(row) { return row.city + ", " + row.country; } }); A listener for the input $("#cities").result(function(event, data, formatted) { selectedCity = (data.regionID); }); And the input: <input type="text" class="textbox" id="cities" name="q" autocomplete="off"> The trouble is when I reload the page, Internet explorer displays last user Input in the text box. However, the variable has no value. I have tried with .reset() but no success. Any ideas why ?

  • VB.net Edit-And-Continue: ignore "unable to apply this change while debugging"

    - by FastAl
    When using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this: "unable to apply this change while debugging" While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options: 1) Restart and recompile and get the program back to the same state 2) Continue debugging without making the change, and risk forgetting 3) Type up a reminder note to make the change All of which are annoying. Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility? 4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this. thanks!

  • Birt Global Integer

    - by matschie
    Hi there I have a Birt Report which read some stuff from a database. After that i want to increment a global Integer for every Detailrow that is loaded. So far i have initialized a global Integer with the following lines: importPackage(Packages.java.lang); reportContext.setPersistentGlobalVariable("minTotalPlus", new Integer(0)); After that i added the following line into a field in my detail row: reportContext.setGlobalVariable("minTotalPlus", new Integer reportContext.getGlobalVariable("minTotalPlus")) + 1); When i preview the report i get an "java.lang.NumberFormatException: null" which means that the global variable is null. Why is that so? How could I fix that?

  • Is SynchronizationContext.Post() threadsafe?

    - by cyclotis04
    This is a pretty basic question, and I imagine that it is, but I can't find any definitive answer. Is SynchronizationContext.Post() threadsafe? I have a member variable which holds the main thread's context, and _context.Post() is being called from multiple threads. I imagine that Post() could be called simultaneously on the object. Should I do something like lock (_contextLock) _context.Post(myDelegate, myEventArgs); or is that unnecessary? Edit: MSDN states that "Any instance members are not guaranteed to be thread safe." Should I keep my lock(), then?

  • Where to start when programming process synchronization algorithms like clone/fork, semaphores

    - by David
    I am writing a program that simulates process synchronization. I am trying to implement the fork and semaphore techniques in C++, but am having trouble starting off. Do I just create a process and send it to fork from the very beginning? Is the program just going to be one infinite loop that goes back and forth between parent/child processes? And how do you create the idea of 'shared memory' in C++, explicit memory address or just some global variable? I just need to get the overall structure/idea of the flow of the program. Any references would be appreciated.

  • ActionScript: Type coercion problem with BlazeDS/AMF and class interfaces

    - by mike
    Hi, I've got a problem with type coercion in a Java/Hibernate/BlazeDS/Flex-Setup. First of all, my classes look like this: --- JAVA --- Interface I (Abstract) Class A implements I Class B extends A --- ActionScript --- Interface I Class A implements I Class B extends A I got RemoteClass-Meta-Tags in all ActionScript-Classes/Interfaces I, A and B. Package structure and Class/Interface names are exactly the same. Now here's the problem: My Java Service successfully retrieves objects of class B from my database via Hibernate. I got another class C which has a member property of interface type I, so it should be possible to assign an object of type B. But for some reason i get the following error message: TypeError: Error #1034: cannot convert Object@28b44a89 to package.name.I I checked the Java object type in the service and it is of type B and seems to be totally fine. Why can't the object of type B be assigned to a member variable of type I? This is driving me nuts. Thanks in advance.

  • OS memory allocation addresses

    - by user1777914
    Quick curious question, memory allocation addresses are choosed by the language compiler or is it the OS which chooses the addresses for the memory asked? This is from a doubt about virtual memory, where it could be quickly explained as "let the process think he owns all the memory", but what happens on 64 bits architectures where only 48 bits are used for memory addresses if the process wants a higher address? Lets say you do a int a = malloc(sizeof(int)); and you have no memory left from the previous system call so you need to ask the OS for more memory, is the compiler the one who determines the memory address to allocate this variable, or does it just ask the OS for memory and it allocates it on the address returned by it?

    - by marc
    Welcome, In short, my website use BBcode system, and i want allow users to preview message without posting it. I'm using JQuery library. I need 3 actions. 1) When user click in textarea i want display DIV what will contain preview, i want animate opening. 2) When user typing, i want dynamical load parsed by PHP code to DIV.

  • Pygame program that can get keyboard input with caps

    - by None
    I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I relize this is because the program ignores shift input and instead writes the text if it's number is under 128. I have thought of setting a variable when shift is pressed then capitalizing if it was true, but string capitalization only woks on letters, not things like numbers or semicolons. Is there maybe a number I can add to the ascii number typed to modify it if shift is pressed, or something else?

  • Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • Problem with filling dataset

    - by Brian
    This is a small portion of my code file. Each time my debugger reaches the line 'NewDA.Fill(NewDS);' at runtime it jumps to the catch. I'm positive the daynumber variable gets a value that's present in the database and I've tried the query outside of the codefile on my database and it works fine. I'm also using the connectionstring 'db' on more parts of the code with successful results. string QueryNew = "SELECT activityname AS [Name], activitycategorynumber AS [Category] " + "FROM ACTIVITY WHERE daynumber = @daynumber"; SqlCommand NewCmd = new SqlCommand(QueryNew, db); NewCmd.Parameters.Add("@daynumber", SqlDbType.Int).Value = daynumber; SqlDataAdapter NewDA = new SqlDataAdapter(NewCmd); DataSet NewDS = new DataSet(); NewDA.Fill(NewDS);

  • Drag and Drop text - What am I missing?

    - by Harvey
    I am trying to add drag-and-drop text to my Doc-View App. I added the COleDropTarget variable to the view class, registered it in OnCreate(). I added OnDragEnter(), OnDragOver(), OnDragLeave() and OnDrop() to that class as virtual overrides, but none of them are ever called. I previously had added m_pMainWnd-DragAcceptFiles(TRUE); to my App class. I tried commenting out that statement, but no affect. I tried using Spy++ to see where the messages go while I do a drag, but it logs nothing at all while I am dragging the text around in the App. What do I need? Or what else can I try, to narrow down the problem? TIA, Harvey

  • How to prevent Closure Compiler from renaming "true", "false" and "null"

    - by Armagan Amcalar
    Google Closure Compiler renames all "true", "false" and "null" occurences in code like; var s = true, x = null, V = false; and uses these shorthands instead; in conditions such as; if (someVariable == s) now; Google Analytics code defines it's own "s" variable; overriding the value "true"; and as you can see this causes a lot of problems. I don't want to change GA code; I just want Closure Compiler to quit renaming true etc. Externs do not work. Do you know any way to accomplish this?

  • How do I put my return data from an asmx into JSON? I'm having trouble finding decent literature

    - by jphenow
    I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance.

  • How to browse a Matrix returned by the OpenCV2.0 Canny() function ?

    - by user290613
    Hi all, I've been browsing the web to get an answer but no way to put my hand on it. I call the Canny function that fills me a matrix Canny(src, dst, 220, 299, 3 ); the dst variable is now a Matrix that is according to me of type CV_8UC1, 8bit, 1channel. Now I would like to browse this matrix according to rows and columns, so there was a trick that I've seen on stackoverflow dst.at<uchar*>(3, 5) In my case it crashes. (Assertion Failed, unknown function, cxmat.hpp line 450) My matrix information are myMatrix.width() = 181 myMatrix.height() = 65 One more thing, when I do std::cout << dst.depth() << std::endl; It always retrieves me 0 and not 8 (which I guess Im suppose to get) Thank you very much for all who will reply,

  • jQuery style Constructors in PHP

    - by McB
    Is there a way to instantiate a new PHP object in a similar manner to those in jQuery? I'm talking about assigning a variable number of arguments when creating the object. For example, I know I could do something like: ... //in my Class __contruct($name, $height, $eye_colour, $car, $password) { ... } $p1 = new person("bob", "5'9", "Blue", "toyota", "password"); But I'd like to set only some of them maybe. So something like: $p1 = new person({ name: "bob", eyes: "blue"}); Which is more along the lines of how it is done in jQuery and other frameworks. Is this built in to PHP? Is there a way to do it? Or a reason I should avoid it?

  • [PHP] Invalid argument supplied for foreach()

    - by Roberto Aloi
    It often happens to me to handle data that can be either an array or a null variable and to feed some foreach with these data. $values = get_values(); foreach ($values as $value){ ... } When you feed a foreach with data that are not an array, you get a warning: Warning: Invalid argument supplied for foreach() in [...] Assuming it's not possible to refactor the get_values() function to always return an array (backward compatibility, not available source code, whatever other reason), I'm wondering which is the cleanest and most efficient way to avoid these warnings: Casting $values to array Initializing $values to array Wrapping the foreach with an if Other (please suggest)
