  • jQuery - How can I temporarily disable the onclick event listener after the event has been fired?

    - by aldux
    How can I temporarily disable the onclick event listener, (jQuery preferred), after the event has been fired? Example: After the user clicks on the button and fires this function below, I want to disabled the onclick listener, therefore not firing the same command to my django view. $(".btnRemove").click(function(){ $(this).attr("src", "/url/to/ajax-loader.gif"); $.ajax({ type: "GET", url: "/url/to/django/view/to/remove/item/" + this.id, dataType: "json", success: function(returned_data){ $.each(returned_data, function(i, item){ // do stuff }); } }); Thanks a lot, Aldo

  • How to convert an Info.plist file from mac os project to iphone project?

    - by Tom Pace
    I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's Info.plist files are Mac OSX project Info.plist files. This is an iPhone engine, and so I cannot understand why the Info.plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings. Edit - Opening the plist file in Xcode or Property List Editor and then trying to add a key such as "Icon already includes gloss and bevel effects" will not work in this iPhone project because it is not in the list. However, "Cocoa Java Application" and others are available!

  • How to corelate gtk.ListStore items with my own models

    - by Victor Stanciu
    Hello, I have a list of Project objects, that I display in a GTK TreeView. I am trying to open a dialog with a Project's details when the user double-clicks on the item's row in the TreeView. Right now I get the selected value from the TreeView (which is the name of the Project) via get_selection(), and search for that Project by name in my own list to corelate the selection with my own model. However, this doesn't feel quite right (plus, it assumes that a Project's name is unique), and I was wondering if there is a more elegant way of doing it.

  • How could I do something like this in a XML schema?

    - by chobo2
    Hi I want to mass create some users and I want to set the users timezone automatically. However I am using timezones generated by this Dictionary<string, TimeZoneInfo> storeZoneName = TimeZoneInfo.GetSystemTimeZones().ToDictionary(z => z.DisplayName); So I need the names to be exactly like the ones this list returns. So can I put like a constraint on that xml node that the name has to exactly match one of the names. So I am guessing I will need to write this list somewhere in the file and that's what I am not sure if you can do something like that in a schema.

  • Excel VBA: can delete validation but not add new one

    - by user1882965
    My code is as follows If Cells(Target.Row, 2) = "" And (Cells(Target.Row, 3) = "" Or Cells(Target.Row, 3) = "") Then Sheets("MySheet").Activate Cells(Target.Row, 3).Activate ActiveCell.Validation.Delete If (Cells(Target.Row, 2) = "Type A") Then ActiveCell.Validation.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:=xlBetween, Formula1:="=AvailableVersions" ElseIf (Cells(Target.Row, 2) = "Type B") Then ActiveCell.Validation.Delete Else ActiveCell.Validation.Add Type:=xlValidateWholeNumber, AlertStyle:=xlValidAlertInformation, Formula1:="0", Formula2:="9999999" End If End If So the issue I am having comes whenever I reach ActiveCell.Validation.Add Run Time Error '1004': Application-defined or object-defined error Not a very helpful error, and also this occurs with both number and list validation type, so I am sure it is not an issue with the list itself which has workbook level scope anyway. It never occurs on ActiveCell.Validation.Delete which I find weird? I have been all over google trying to find a solution, and most suggest that it is caused by running dynamic validation code from a button which hogs focus despite the Activate call, but I am running on sheet change event rather than on button press so I don't think this is my issue - any ideas? I've wasted basically a whole day on this! :(

  • Create IEnumerable<T>.Find()

    - by Brian
    I'd like to write: IEnumerable<Car> cars; cars.Find(car => car.Color == "Blue") Can I accomplish this with extension methods? The following fails because it recursively calls itself rather than calling IList.Find(). public static T Find<T>(this IEnumerable<T> list, Predicate<PermitSummary> match) { return list.ToList().Find(match); } Thanks!

  • Is there any way to do a WER "Request Additional Files" for the windows temp directory?

    - by Jason Mathison
    My company has had numerous crashes reported to windows error reporting due to what looks like an install problem. The logs for our installs are typically in the windows\temp directory. I would like to include the install log file as a "Request Additional Files" entry, however there doesn't seem to be any way to get to a subdirectory of the list of environmental Variables that are provided. The windows temp directory is not in the list of values that you can work from, so I am stuck. In general, I don't understand how it is possible to get at almost anything of use via the "Request Additional Files". For example, the %programfiles% directory shouldn't contain any useful files, they should be in a subdirectory for your product. What am I missing?

  • How to convince someone, that reading books(blogs, so..) is important?

    - by hgulyan
    Dear all, please, help me to convince, that no matter what you're doing, you need to read some stuff, try to learn something new. They say, that they don't want to sit in front of computer in the end of a day and they don't have opportunity to read in working hours, or they're too tired for doing something. Have you faced this kind of situation? What did you do?

  • Return popupmenu selection in MATLAB using one line of code

    - by Doresoom
    I have a GUI which uses a selection from a popupmenu in another callback. Is there a way to return the selected value of the popupmenu in only one line without creating any temporary variables? I've tried several solutions, but I've only managed two lines with one temporary variable: Three lines: list=get(handles.popupmenu1,'String'); val=get(handles.popupmenu1,'Value'); str=list{val}; Two lines: temp=get(handles.popupmenu1,{'String','Value'}); str=temp{1}{temp{2}}; Can anyone shave it down to one? PS, It's a dynamic menu, so I can't just use get(handles.popupmenu1,'Value') and ignore the string component altogether.)

  • A datastructure for Robotic Sort

    - by amit.codename13
    I am trying to solve this problem : https://www.spoj.pl/problems/CERC07S/ I have identified that i need a datastructure in which reversing operations have lesser time complexity. I tried to create one using a doubly linked list, in which (i thought) reversing can be done in O(1) by just changing a value associated with the starting and ending node which indicates the direction of traversing the list. I tried to implement it but got stuck. Maybe the approach is wrong! Are trees applicable here? If yes, how? Any ideas or links are appreciated? Thanks in advance.

  • JQuery animation

    - by Ravindra Soni
    I am using following code for animation using jquery. When I click on a list element, the corresponding div slides down and opacity goes to '1'. When I click other list element, the previous one goes up and fades, and the next one come down. var id_prev; var id_new; $("#tag ul li ").click(function(event){ var i = $(this).index()+1; var id_new="#person"+i; if(id_new != id_prev){ $(id_prev).animate({top:'300px',opacity:'0'},500); $(id_prev).delay(200).css({'z-index':'0'}); $(id_new).delay(200).css({'z-index':'300'}); $(id_new).delay(200).animate({top:'300px',opacity:'0'},500); $(id_new).delay(200).animate({top:'330px',opacity:'1'},500); id_prev = id_new; } });

  • Avoiding class_eval in Ruby metaprogramming

    - by Peter
    I want to have a return_empty_set class method in Ruby, similar to the attr_reader methods. My proposed implementation is class Class def return_empty_set *list list.each do |x| class_eval "def #{x}; Set.new; end" end end end and example usage: class Foo return_empty_set :one end Foo.new.one # returns #<Set: {}> but resorting to a string seems like quite a hack. Is there a cleaner or better way to write this, perhaps avoiding class_eval? Or is this the best way to go?

  • Find directories not containing a specific directory

    - by Morgan ARR Allen
    Been searching around for a bit and cannot find a solution for this one. I guess I'm looking for a leaf-directory by name. In this example I'd like to get a list of directories call 'modules' that do NOT have a subdirectory called module. modules/package1/modules/spackage1 modules/package1/modules/spackage2 modules/package1/modules/spackage3/modules modules/package1/modules/spackage3/modules/spackage1 modules/package2/modules/ The list I desire would contain modules/package1/modules/spackage3/modules/ modules/package2/modules/ All the directories named module that do not have a subdirectory called module I started with trying something this with no luck find . -name modules \! -exec sh -c 'find -name modules' \; -exec works on exit code, okay lets pass the count as exit code find . -name modules -exec sh -c 'exit $(find {} -name modules|grep -n ""|tail -n1|cut -d: -f1)' \; This should take the count of each subdirectory called modules and exit with it. No such love.

  • Java loading user-specified classes at runtime

    - by user349043
    I'm working on robot simulation in Java (a Swing application). I have an abstract class "Robot" from which different types of Robots are derived, e.g. public class StupidRobot extends Robot { int m_stupidness; int m_insanityLevel; ... } public class AngryRobot extends Robot { float m_aggression; ... } As you can see, each Robot subclass has a different set of parameters. What I would like to do is control the simulation setup in the initial UI. Choose the number and type of Robots, give it a name, fill in the parameters etc. This is one of those times where being such a dinosaur programmer, and new to Java, I wonder if there is some higher level stuff/thinking that could help me here. So here is what I've got: (1) User Interface Scrolling list of Robot types on the left. "Add " and "<< Remove" buttons in the middle. Default-named scrolling list of Robots on the right. "Set Parameters" button underneath. (So if you wanted an AngryRobot, you'd select AngryRobot on the left list, click "Add" and "AngryRobot1" would show up on the right.) When selecting a Robot on the right, click "Set Parameters..." button which would call yet another model dialog where you'd fill in the parameters. Different dialog called for each Robot type. (2) Data structures an implementation As an end-product I think a HashMap would be most convenient. The keys would be Robot types and the accompanying object would be all of the parameters. The initializer could just retrieve each item one and a time and instantiate. Here's what the data structures would look like: enum ROBOT_TYPE {STUPID, ANGRY, etc} public class RobotInitializer { public ROBOT_TYPE m_type; public string m_name; public int[] m_int_params; public float[] m_float_params; etc. The initializer's constructor would create the appropriate length parameter arrays based on the type: public RobotInitializer(ROBOT_TYPE type, int[] int_array, float[] float_array, etc){ switch (type){ case STUPID: m_int_params = new int[STUPID_INT_PARAM_LENGTH]; System.arraycopy(int_array,0,m_int_params,0,STUPID_INT_PARAM_LENGTH); etc. Once all the RobotInitializers are instantiated, they are added to the HashMap. Iterating through the HashMap, the simulation initializer takes items from the Hashmap and instantiates the appropriate Robots. Is this reasonable? If not, how can it be improved? Thanks

  • Computer Vision Website Image Slideshow help

    - by msandbot
    Hi, I'm making an online display of the output of a computer vision algorithm. After running the algorithm I am left with a folder of about 1000 16 bit .tiff files. I need to put those on the website in a list for so that the researchers can click through and find the list. Also there needs to be an image frame with an "animated gif" feel that can be started stopped and played in reverse. Any ideas on the best way to do this? What language to use? I made a simple website in Ruby on Rails but I don't know if it has the capabilities to do what I require.
