  • How do I output JSON columns in jQuery

    - by Mel
    I'm using the qTip jQuery plugin to create dynamic tool tips. The tooltip sends an id to a cfc which runs a query and returns data in JSON format. At the moment, the tooltip loads with the following: {"COLUMNS:" ["BOOKNAME","BOOKDESCRIPTION"["MYBOOK","MYDESC"]]} Here's the jQuery $('#catalog a[href]').each(function() { var gi = parseInt($(this).attr("href").split("=")[1]) $(this).qtip( { content: { url: 'cfcs/viewbooks.cfc?method=bookDetails', data: { bookID: gi }, method: 'get', title: { text: $(this).text(), button: 'Close' } }, api :{ onContentLoad : function(){ } }, }); }); As I mentioned, the data is returned successfully, but I am unsure how to output it and format it with HTML. I tried adding content: '<p>' + data.BOOKNAME + '' to api :{ onContentLoad : function(){ ..... to see if I could get it to output something, but I get a 'data is undefined error' What is the correct way to try and output this data with html formatting? Many thanks!

  • PHP - WideImage class cropping

    - by Kolind
    I am trying to crop a large image to make thumbnails. But I can't get WideImage to save the file. I've tried the following: 1st method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->saveToFile('../files/thumb/thumb_' . $file_name); 2nd method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->copy('../files/thumb/thumb_' . $file_name); But nothing seems to happen, when I am performing any of these methods. I am getting no errors and no thumbnails. Am I doing something wrong here?

  • Confusion about Mono?

    - by emalamisura
    Ok, so I was perusing the mono site and noticed there are Novell tools I can purchase for Visual Studio that will let me choose to compile in Mono? My confusion is, if I am using a tool set such as MVC 2 and other Frameworks, and I use those tools to compile to mono, how exactly does that play into things? I mean don't those tool sets need to be recompiled using Mono?

  • Manage multiple Jlabel's events

    - by IMAnis_tn
    I have a left Panel with multiples Jlabels which i use them as buttons to change a Main Panel's content which is layouted with a CardLayout. I cant work perfectly with these events: mouseEntered : to make highlight effect to the jlabel mouseExited : to take off the highlight effect. mouseClicked : to change the content of the main Panel and start some threads The problem here that can't found an event or a method tell me that another Jlabel has been clicked so i can stop my threads started in the mouseClicked event, OR an event or method tell me that a JPanel in the CardLayout has been displayed or hidden.

  • RTTI and Portability in C++

    - by Joshua
    If a compiler doesn't "support" RTTI, does that mean that the compiler can not handle class hierarchies that have virtual functions in them? Or have I been misunderstanding the literature about how RTTI isn't portable, and the issues lie elsewhere?

  • Pass Session data to a Class Library without using a bunch of constructors?

    - by sah302
    Hi all, I've got my application here where literally every object has a lastUpdatedBy property. The information I put into here is the person's username, which is retrieved from the session("username") variable. How can I pass this data to my DAL in the class library? At first I was just passing in the value into each method, but this is ridiculous I thought, there should be no reason to do that every time a method is called. Then I thought well if I just put it in a constructor for each of the DAL related classes, that will make it even easier. However, even still on any given page, I've got a plethora of New() declarations, for which every single line I need to pass in the session username casted as a string. Is there an even still more efficient way of doing this so that I could only declare this in one place, and everything will know what it is and I can pass it to classes in a class library?

  • How do I avoid boxing/unboxing when extending System.Object?

    - by Robert H.
    I'm working on an extension method that's only applicable to reference types. I think, however, it's currently boxing and unboxing the the value. How can I avoid this? namespace System { public static class SystemExtensions { public static TResult GetOrDefaultIfNull<T, TResult>(this T obj, Func<T, TResult> getValue, TResult defaultValue) { if (obj == null) return defaultValue; return getValue(obj); } } } Example usage: public class Foo { public int Bar { get; set; } } In some method: Foo aFooObject = new Foo { Bar = 1 }; Foo nullReference = null; Console.WriteLine(aFooObject.GetOrDefaultIfNull((o) => o.Bar, 0)); // results: 1 Console.WriteLine(nullReference.GetOrDefaultIfNull((o) => o.Bar, 0)); // results: 0

  • Using the JNotify library, how can you tell if a deleted file was a file or a directory?

    - by Moeri
    For those unfamiliar with JNotify, this is a library which provides an easy way to monitor events in a directory. For instance, when a file gets deleted in the selected folder, the method "fileDeleted" gets called, along with a few parameters. Here's an example of the fileDeleted method: public void fileDeleted(int wd, String rootPath, String name) { print("deleted " + rootPath + " : " + name); } Now, I would like to know if the deleted file was a file or directory. My usual approach is to create a new File object with the given path, and use the methods isFile() and isDirectory() However, since this file is already deleted, these methods always return false. So here's my concrete question: I have the path to a deleted file or directory, how can I tell wether it was a file or a directory? Is there a workaround to this? What's the best practice to do here? Thank you in advance.

  • asp:calendar not work correctly in MVC

    - by TStamper
    I have an asp:calendar on my view page and as I hover over it..it shows a javascript postback status bar. but I have an asp:button also on the same page and when I hover over it. The action from the controller is in the status bar..because I have an onClick attribute for the button that triggers an action on the server side. and in the asp:calendar I also have a trigger event OnSelectionChanged the has a method on the server side...but as I said when I hover over the calendar to pick a date in the status bar it shows:javascript:_doPostBack($ct100ContentPlaceHolder?mycalendar',''3270) and when I click a date I receive an error that says object doesnt support this method..Also mycalendar is the id name of the asp:calendar

  • c++/cli pass (managed) delegate to unmanaged code

    - by Ron Klein
    How do I pass a function pointer from managed C++ (C++/CLI) to an unmanaged method? I read a few articles, like this one from MSDN, but it describes two different assemblies, while I want only one. Here is my code: 1) Header (MyInterop.ManagedCppLib.h): #pragma once using namespace System; namespace MyInterop { namespace ManagedCppLib { public ref class MyManagedClass { public: void DoSomething(); }; }} 2) CPP Code (MyInterop.ManagedCppLib.cpp) #include "stdafx.h" #include "MyInterop.ManagedCppLib.h" #pragma unmanaged void UnmanagedMethod(int a, int b, void (*sum)(const int)) { int result = a + b; sum(result); } #pragma managed void MyInterop::ManagedCppLib::MyManagedClass::DoSomething() { System::Console::WriteLine("hello from managed C++"); UnmanagedMethod(3, 7, /* ANY IDEA??? */); } I tried creating my managed delegate and then I tried to use Marshal::GetFunctionPointerForDelegate method, but I couldn't compile.

  • Why wouldn't I be able to establish a trust relationship for a SSL/TLS channel?

    - by Abe Miessler
    I have a piece of .NET code that is erroring out when it makes a call to HTTPWebRequest.GetRequestStream. Here is the error message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. I've read a few things that suggest that I might need a certificate on the machine running the code, but i'm not sure if that's true or how to do it. If I need to get a certificate, how do I do it? Code: var request = (HttpWebRequest)HttpWebRequest.Create(requestUrl); //my url request.Method = StringUtilities.ConvertToString(httpMethod); // Set the http method GET, POST, etc. if (postData != null) { request.ContentLength = postData.Length; request.ContentType = contentType; using (var dataStream = request.GetRequestStream()) { dataStream.Write(postData, 0, postData.Length); } }

  • How can I create a Zerofilled value using JavaScript?

    - by Wilco
    What is the recommended way to zerofill a value in JavaScript? I imagine I could build a custom function to pad zeros on to a typecasted value, but I'm wondering if there is a more direct way to do this? Note: By "zerofilled" I mean it in the database sense of the word (where a 6-digit zerofilled representation of the number 5 would be "000005").

  • Simple Scala syntax - trying to define "==" operator - what am I missing?

    - by Alex R
    While experimenting with some stuff on the REPL, I got to a point where I needed something like this: scala class A(x:Int) { println(x); def ==(a:A) : Boolean = { this.x == a.x; } } Just a simple class with an "==" operator. Why doesn't it work??? Here's the result: :10: error: type mismatch; found : A required: ?{val x: ?} Note that implicit conversions are not applicable because they are ambiguous: both method any2ArrowAssoc in object Predef of type [A](x: A)ArrowAssoc[A] and method any2Ensuring in object Predef of type [A](x: A)Ensuring[A] are possible conversion functions from A to ?{val x: ?} class A(x:Int) { println(x); def ==(a:A) : Boolean = { this.x == a.x; } } ^ This is scala 2.8 RC1. Thanks

  • Java Webservice with generic methods

    - by danby
    Hi, I was wondering if it is possible to make a generic webservice method in java like this: @WebMethod public <T extends Foo> void testGeneric(T data){ However when I try to consume this with a Java client I get an error stating: [ERROR] Schema descriptor {http://####/}testGeneric in message part "parameters" is not defined and could not be bound to Java. I know it is possible to make a method that takes a parameter such as List and this generates correctly using JAX-WS. I don't mind if there is a solution that means I am tied to using only a particular technology. Thanks, Dan.

  • Returning messages in Smalltalk

    - by Zachary
    I have a Dictionary of objects I have created in smalltalk, which I am iterating over by enumerating it based on the key/value pairs. For value object in the dictionary, I am calling a method on that object. Based on certain conditions, I would like for this object to be able to add a new member to dictionary, and possibly delete another one. I've been looking at the 'Perform' and 'Messages' facilities in Smalltalk, but I'm not sure if it is even possible to do what I'm trying to do - is it possible to return a message (or multiple messages), which another object can process and perform? For example, could my method return 'removeKey: 19' and 'add object' at the same time? I am using GNU Smalltalk, if it matters.

  • Why membership provider is not generic?

    - by Timmy O' Tool
    I have to confess that I hate membership provider. The default implementation is not very appropriate normally and I haven't seen so far a good implementation of a custom membership provider, probably because this is not possible :-) So the question is: In your opinion: which are the reasons for not having membership/role provider as a generic class? I mean, why Microsoft didn't selected this approach.

  • Collectable<T> serialization, Root Namespaces on T in .xml files.

    - by Stacey
    I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored.

  • How Two Programs Can Talk To Each Other In Java?

    - by Arnon
    My first time here... I want to ?reduce? the CPU usage/ROM usage/RAM usage - in general ?speaking?, all system resources that my App use - how doesn't? :) For this reason i want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which mean, to call the update method(that i wrote) that found in the Main class. How can i call the update method in the Main program from the preferences program? Or in the other hand... There is a way to build preferences window that take system resources just when it's appear? Is this approach - of separating programs and let them talk to each other(somehow) - is a right approach for speeding up my programs? tnx

  • How to Check .Net 2.0 assembly for Calls to .Net 3.5

    - by Paul Farry
    I've found an issue I believe where an assembly is making a call to a .Net3.5 method in a .Net2.0 only environment. (None on the .Net service packs nor .Net 3.5 is installed) I'd like to know if there are any programs that I can run like FXCop to check an assembly for adherence to only making method calls that are available in .Net 2.0 without the 3.5 extensions that were added. I've been bitten by this before and I'd like to have a way to check assemblies so that before they are released they can be checked to prevent these kinds of issues. Please don't say require .Net 3.5 because whilst I'd like to go to this, it's just not possible at this point.
