  • jquery draggable accept: classpath

    - by heldopslippers
    Hi guys.. I have problems with the following bit of javascript/jquery code: this.droppable = function(){ $('.imageWindow .body .item').draggable(); $('.groupWindow .body .item').droppable({ accept: $(".imageWindow .body .item"), over: function(event, ui) { alert("this is valid!"); }, drop: function(){ alert('dropped'); } }); } As you maybe know it is not possible to pass the following in the accept option: $(".imageWindow .body .item") But what is possible ? I want to pass a "class path" as an accept option ! It is probably a simple answer but i can't figure it out. Of course i could do: accept: ".item" But because "groupWindow .body .item" is a sortable it would also accept himself! Thanxs if you can help me!

  • Alternatives to C++ Reference/Pointer Syntax

    - by Jon Purdy
    What languages other than C and C++ have explicit reference and pointer type qualifiers? People seem to be easily confused by the right-to-left reading order of types, where char*& is "a reference to a pointer to a character", or a "character-pointer reference"; do any languages with explicit references make use of a left-to-right reading order, such as &*char/ref ptr char? I'm working on a little language project, and legibility is one of my key concerns. It seems to me that this is one of those questions to which it's easy for a person but hard for a search engine to provide an answer. Thanks in advance!

  • Get list of running processes, get active process (and it's application) Flex/AIR

    - by Adam Kiss
    Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)

  • is there any Simple opensource live audio streaming Server using WCF? (see specification below)

    - by Ole Jak
    is there any Simple opensource live audio streaming Server using WCF? I need it to have simple structure: it should listen to some url format like http://example.com/service/stream?write&id=ANY_STRING and if any data comes to such address format it'll start making it avaliable by something like this http://example.com/service/stream?read&id=ANY_STRING Main thing here to be able to stream live data thru WCF service not buffering it just sharing stream. So can please any one help me with such idea? I think not only I have seen such problem with WCF alot on different sites so answer will help the WCF comunyty alot. I hope. BTW: I know some people say WCF is not prepared for live streaming over bacikHTTPbinding but hey! We all need it to, and we ask MS alot so some day they'll make it beter and we all want to be prepared for it.

  • What traits can hint a teenager he should pursue software development career?

    - by sharptooth
    We're gonna have a day when employees' kids will visit our company office. The idea is that they will come see "how parents work", "how cool stuff is done", have fun, etc. Kids will be up to 17 years old. Now I suppose some of the teenagers already think of what they wanna do when they finally grow up and will ask questions like "how can I tell I should get a degree in software engineering and not in logistics/finances/whatever?" So I think we better be prepared and ready to answer those questions so that those who really fit don't waste time but use their potential to the full. What traits that already emerge in teenage years indicate that a person could become a very good software developer?

  • Adding Controls Programatically

    - by Mike Keller
    I have a page I need to build out where depending on the selection the user made on a form on the page prior it displays a different set of questions for them to answer. So say the user selects Reason A from the form on page edit, then it needs to display Questions 1 and 2 on page edit_confirmation. But if they select Reason B then it needs to display Questions 3 and 4. I'm grabbing the reason code from the query string and have a switch statement set up, but I can't find anywhere how to output different controls. If Questions 1 and 2 are supposed to show up, one could be a text box and the other a checkbox, but if questions 3 and 4 are supposed to show up one may need to be a dropdown list and a checkbox.

  • Devise role based routing

    - by teknull
    I have an app with multiple users. Each user as a theoretical role (user, client, etc). I've designed a view/controller for each user type. I want to be able to login each type of user do a different root url and lock them to it. Originally I was going to add a column to Users in Devise called role and so I can differentiate the users. The problem I'm having is how to say in routes.rb if current_user.role == "client" root :to = 'controller#index' Once they are logged in to the page I also want to keep them from being able to visit any of my other paths ie: domain.com/calls domain.com/units I've been looking into cancan to run alongside Devise but I'm not sure if this is the answer.

  • Fallback to another existing MIME type when the required is missing in Rails

    - by fifigyuri
    I want to extend the existing supported HTML type of my site by support for iPhone. For this I registered a new MIME type. I created a layout for iphone and also converted some of the html views to iphone version. However, I did not convert all of the html.erb files. I do not see the reason to convert all views, some of them should not change, some partials simply just remain the same. I guess there should be a solution for this case. I tried to search for ways how to fallback to an existing format, but did not find any answer. Does a way to define fallback for MIME types in Rails exist? How does it work? If it doesn't exist and thus I wanted to solve the issue not the right way, what could simply solve the task of extending an existing site by another format? Thanks for your suggestions.

  • Write the longest possible loop.

    - by Abhay
    Hello Group, Recently I was asked this question in a technical discussion. What is the longest possible loop that can be written in a programming language? This loop has to be as long as possible and yet not an infinite loop and should not end-up crashing the program (Recursion etc...) I honestly did not know how to attack this problem, so I asked him if is it practically possible. He said using some computer science concepts, you can arrive at a hypothetical number which may not be practical but nevertheless it will still not be infinite. Anyone here; knows how to analyse / attack this problem. P.S. Choosing some highest limit for a type that can store the highest numerical value is apparently not an answer. Thanks in advance,

Sorry for posting an unrelated program question. I am not receiving an answer anywhere else, and I can see that there are serveral question regarding azure which are not program related here. Thank you!

  • How is fseek() implemented in the filesystem?

    - by pajton
    This is not a pure programming question, however it impacts the performance of programs using fseek(), hence it is important to know how it works. A little disclaimer so that it doesn't get closed. I am wondering how efficient it is to insert data in the middle of the file. Supposing I have a file with 1MB data and then I insert something at the 512KB offset. How efficient would that be compared to appending my data at the end of the file? Just to make the example complete lets say I want to insert 16KB of data. I understand the answer varies depending on the filesystem, however I assume that the techniques used in common filesystems are quite similar and I just want to get the right notion of it.

  • Can NTFS-Search(An OSS project) scan any file on NTFS volume?

    - by Benjamin
    I want to apply NTFS-Search to our project. Our project have to find the files which we specified.(fast and exactly!) But I'm not sure the program(NTFS-Search) works well. What if the file specified is system file? What if the file is being opened by a process with NO_READ_SHARE_MODE? Do you think NTFS-Search can find any files? I don't know about NTFS filesystem well. So I can't find the answer myself. Is there anyone who knows that? I tried to find their email address, but I couldn't find. Thanks in advance.

  • Can a Perl subroutine return data but keep processing?

    - by Perl QuestionAsker
    Is there any way to have a subroutine send data back while still processing? For instance (this example used simply to illustrate) - a subroutine reads a file. While it is reading through the file, if some condition is met, then "return" that line and keep processing. I know there are those that will answer - why would you want to do that? and why don't you just ...?, but I really would like to know if this is possible. Thank you so much in advance.

  • What characters are widely supported in CSS class names?

    - by last-child
    As detailed here among other places, the only valid characters in a html/css class name is a-z, A-Z, 0-9, hyphen and underscore, and the first character should be a letter. But in practice, what characters are in fact supported by most browsers? More specifically, I wonder what browsers properly understands a slash (/) in a class name, and what browsers support class names starting with a number. I'm primarily interested in getting an answer for html rather than xhtml, in case there is a difference. Thank you.

  • How to close a form in UserControl

    - by FJPoort
    I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that. Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code: private void btnCancel_Click(object sender, EventArgs e) { ProjectInfo infoScreen = (ProjectInfo)this.Parent; infoScreen.Close(); } This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?

  • Missing Status Bar in Visual Studio?

    - by Marcel
    Note: This question and answer is a full copy from Kelly Brownsbergers Blog. I do post it as a convenience to others. From time to time, my status bar disappears. I used to believe this was due to a botched install or add-in. I recently upgraded to Team System Test Edition, and my status bar again disappeared. For the last few weeks I’ve been trying to figure out a time to do a full reinstall. To not take rep for this, I have marked it communitiy wiki.

  • What are the things Java got right?

    - by hamletdarcy
    What are the things that Java (the language and platform) got categorically right? In other words, what things are more recent programming languages preserving and carrying forward? Some easy answer are: garbage collection, a VM, lack of pointers, classloaders, reflection(?) What about language based answers? Please don't list the things Java did wrong, just right. (note by Mark Harrison) This is an interesting and useful question, especially for those of us who don't use java regularly. I'm voting for reopening. Please don't close as argumentative, as it doesn't seem to be causing any arguments.

  • wxPython - wx.ChildFrame

    - by Dunwitch
    I'm sure this is simple, but I can't seem to find the answer. While using wx.MDIParentFrame, I open a new window with wx.MDIChildFrame. There is static text on the ParentFrame, and once the ChildFrame opens the text gets erased from the ParentFrame? import wx class Frame(wx.MDIParentFrame): def __init__(self): wx.MDIParentFrame.__init__(self, None, -1, "Main Window", size=(800,600), style=wx.DEFAULT_FRAME_STYLE | wx.FRAME_NO_WINDOW_MENU) menu = wx.Menu() menu.Append(100, "&New Window") menu.Append(101, "E&xit") menubar = wx.MenuBar() menubar.Append(menu, "&File") self.SetMenuBar(menubar) self.Bind(wx.EVT_MENU, self.OnNewWindow, id=100) self.Bind(wx.EVT_MENU, self.OnExit, id=101) self.Center() background_text = wx.StaticText(self, id=-1, label="This is background text", pos = (20, 250)) def OnExit(self, evt): self.Close(True) self.Destroy() def OnNewWindow(self, evt): win = wx.MDIChildFrame(self, -1, "Child Window", size = (300, 300), style=wx.DEFAULT_FRAME_STYLE ^ (wx.MAXIMIZE_BOX | wx.RESIZE_BORDER)) win.SetBackgroundColour("#BB00e0") win.Show(True) if __name__ == '__main__': app = wx.PySimpleApp() frame = Frame() frame.Show() app.MainLoop()

  • Merging tables in MySQL - sum up columns

    - by Alan Williamson
    I have an interesting problem, that i am sure has a simple answer, but i can't seem to find it in the docs. I have two separate database tables, on different servers. They are both identical table schema with the same primary keys. I want to merge the tables together on one server. But, if the row on Server1.Table1 exists in Server2.Table2 then sum up the totals in the columns i specify. Table1{ column_pk, counter }; "test1", 3 "test2", 4 Table2{ column_pk, counter }; "test1", 5 "test2", 6 So after i merge i want: "test1",8 "test2",10 Basically i need to do a mysqldump but instead of it kicking out raw INSERT statements, i need to do a INSERT..ON DUPLICATE KEY UPDATE statements. What are my options? Appreciate any input, thank you

  • Howto get iframe linking to internal document source using javascript/jQuery?

    - by Tom
    Hi there, I have an iframe with id "appframe", the source is page.html and it's on the same server. I want to get the source of the page using jQuery. alert($("#appframe").contents().find("html").html()); returns <head></head><body></body> even though the document does not contain those tags, it only contains "Default page", so that is exactly what it should return. Any idea how to get the right source script of the whole document using jQuery? Eg. if the document would be "test" then that is exactly what it should return. Please note: I did ask this before a few weeks ago. Unfortunately, I got no solving answer. Because of my lower reputation (~85), I can not request a bounty... This doesn't make much sense to me. Anyway, it forced me to repost this question.

  • Best and shortest books on C++/STL/C#/J2SE to prepare for job inteview/tests

    - by Nerd
    I am a software developer with 10+ years commercial experience, I am comfortable with nearly all of imperative languages. But I realized that most of employers prefer not candidates who is able to deliver good software but those who is trained to answer questions like "what are ten differences between pointers and references in C++" or "what this messy code fragment will print". Last time I have read a book on C++ 15 years ago in secondary school and yes, that was Bjarne Stroustrup. But today I need something quick, without long philosophical explanations about polymorphism etc but with focus to silly interview tests. So, can you recommend any short and effective books to refresh my theoretical knowledge? Thank you.

  • What's the RegEx to make sure that delimiters are escaped?

    - by Kuyenda
    I'm looking for a regular expression that will check whether or not delimiters in a string are escaped with a backward slash. The delimiters I am concerned about are comma (\,), colon (\:), semicolon (\;) and of course the backward slash itself has to be escaped (\). For example, the string "test" should return a match because there are no delimiters in it, and no escaping is necessary. The string "te\;st" would return a match because the semicolon delimiter is escaped. "te;st" and "t\;s:t" would both fail because the both contain at least one delimiter that is not escaped. I know that I need a conditional and a positive look behind, and this is what I have so far, but it is not giving me the expected answer. ^(?<delimiter>[:;,\\])?(?(delimiter)\(?<=(?:\\\\)*\\)k<delimiter>|.)$ Any suggestions on how I can make this work? Thanks.

  • Tips for measuring the parallelism speed-up in multi-core development.

    - by fnCzar
    I have read many of the good questions and answers around multi-core programming how-tos etc. I am familiar with concurrency, IPC, MPI etc but what I need is advice on how to measure speed-up which will help in making a business case of spending the time to write such code. Please don't answer with "well run it with single-core code then multi-core code and figure out the difference". This is neither a scientific nor a reliable way to measure performance improvement. If you know of tools that will do some of the heavy lifting please mention them. Answers pertaining to methodology will be more fitting but listing tools is ok as well.
