  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

  • C# Dictionary<> and mutable keys

    - by Pierreten
    I was told that one of the many reasons strings were made immutable in the C# spec was to avoid the issue of HashTables having keys changed when references to the string keys altered their content. The Dictionary< type allows reference types to be used as a key. How does the dictionary avoid the issue of altered keys that lead to "misplaced" values? Is there a memberwise clone made of an object when used as a key?

  • JQuery UI: is it possible to know where an object has been dropped?

    - by Jack Duluoz
    Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

  • Android layouts within layouts, with separate classes handling their input?

    - by Demonofloom
    Hey all, I have created a program in Java that uses Jpanels within Jpanels. One example of this is having a side view containing buttons that change the main view when pressed. The main view also has buttons that can be used to alter itself. I am trying to re-create this on the android. I have my layout set up from an xml, with a side panel containing buttons and the main view. There is another xml that contains what I want in the main view. Now I am struggling to get this separate xml to be displayed in the main view and can’t figure out how I would get the class to handle its own input. I don’t want to paste the code into the main.xml as I want to keep things object orientated and each view needs some custom elements such as different textviews. An example of what I am trying to convert for the android is below:- //The ViewInt class has its own layout ViewInt tempView = new ViewInt(i, mFloorNo); //The viewInt class is then added to the main window. mainWindowPanel.add(tempView); This small bit of code would create a view, add it to the main view and then any input in the main window is handled by that class, but at the same time any input not in this main window is handled by another class (probably the root class). Any help is greatly appreciated, thanks. To clarify: The program has a side panel layout, containing buttons. And a main view layout that is empty. I am trying to set a .xml layout to this main view layout, and have it so that if any buttons are pressed in that main view then a class for that layout will handle it.

  • Why the compiler is not compiling a line in C++ Builder?

    - by MLB
    Hi boys: I was programming an application in C++ Builder 6, and I had encountered this rare problem: void RotateDice() { Graphics::TBitmap *MYbitmap = new Graphics::TBitmap(); Randomize(); int rn = random(6) + 1; switch (rn) { case 1: { //... break; } //... Some cases... } ShowDice(); //it's a function to show the dice delete MYbitmap; //the compiler don't get it!!!! } In the line "ShowDice()", the compiler jumps to the final of the RotateDice() method, it doesn't "see" the line "delete MYbitmap". When I compile the program, every compiled line shows a little blue point in its left side, but that line don't show the blue point... it's like the compiler don't "see" the line of code. What's happening with that???? Note: Some days ago, I was writing a program in Delphi and I was advice of that problematic issue. Some like that happened to me in Delphi 7... So, waht the problem with that? I am so sorry about my English. I am from Cuba.

  • Biztalk - how do I set up MSMQ load balancing and high availability ?

    - by FullOfQuestions
    Hi, From what I understand, in order to achieve MSMQ load-balancing, one must use a technology such as NLB. And in order to achieve MSMQ high-availability, one must cluster the related Biztalk Host (and hence the underlying servers have to be in a cluster themselves). Yet, according to Microsoft Documentation, NLB and FailOver Clustering technologies are not compatible. See this link for reference: http://support.microsoft.com/kb/235305 Can anyone PLEASE explain to me how MSMQ load-balancing and high-availability can be achieved? thank you in advance, M

  • Python & Pygame: Updating all elements in a list under a loop during iteration

    - by Unit978
    i am working on a program in Python and using Pygame. this is what the basic code looks like: while 1: screen.blit(background, (0,0)) for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == KEYDOWN and event.key == K_c: circle_create = True circle_list.append(Circle()) if event.type == MOUSEBUTTONDOWN and circle_create == True: if clicks == 0: circle_list[i].center() clicks += 1 if event.type == MOUSEMOTION and clicks == 1 and circle_create == True: circle_list[i].stretch() these if statements are under the while loop not the for loop since they dont require input from the user if circle_create == True: circle_list[i].draw_circle() if clicks == 2: clicks = 0 i += 1 circle_create = False pygame.display.update() what i want to do is have the object's function of draw_circle() to be constantly updated by the loop so that the drawn circle is shown for all objects in the list, but since the list is iterated it updates the new object added and the objects already appended are not updated. The program, works, it draws the circles upon user input but the update problem is the only issue i need to solve. Is there any possible way to have all elements in the list of objects being updated by the while loop? i have tried for many days and i have not been able to find a good solution. any ideas are appreciated. Thanks

  • Smart way to execute function in flash from an imported html (or XML) plain text

    - by DomingoSL
    Ok, here is the think. I have a very simple flash program code in AS3, inside this program there is a dynamic textfield html capable. Also i have a database were i will put some information. Each element in the database can be linked to other. For example, this database will contain tourist spots, and they can be related with others in the same database. Ramdom place 1 This interesting spot is near <link to="ramdo2">ramdom place2</link>. And so, so so... The information in the database is retrived by the flash application and it shows the text on the dynamic textfield. I need somehow to tell my flash application that have to be a link to other part of the database, so when the user click the link a function in flash call this new data. The database is a simple Mysql server, and the data is not yet in there, waiting for your suggestions of how to format it and develop the solution. Im a php developer too, so i can make a gateway in PHP to read the MySQL and then retrive some format to flash, an XML for example.

  • C++ stream as a parameter when overloading operator<<

    - by TheOm3ga
    I'm trying to write my own logging class and use it as a stream: logger L; L << "whatever" << std::endl; This is the code I started with: #include <iostream> using namespace std; class logger{ public: template <typename T> friend logger& operator <<(logger& log, const T& value); }; template <typename T> logger& operator <<(logger& log, T const & value) { // Here I'd output the values to a file and stdout, etc. cout << value; return log; } int main(int argc, char *argv[]) { logger L; L << "hello" << '\n' ; // This works L << "bye" << "alo" << endl; // This doesn't work return 0; } But I was getting an error when trying to compile, saying that there was no definition for operator<<: pruebaLog.cpp:31: error: no match for ‘operator<<’ in ‘operator<< [with T = char [4]](((logger&)((logger*)operator<< [with T = char [4]](((logger&)(& L)), ((const char (&)[4])"bye")))), ((const char (&)[4])"alo")) << std::endl’ So, I've been trying to overload operator<< to accept this kind of streams, but it's driving me mad. I don't know how to do it. I've been loking at, for instance, the definition of std::endl at the ostream header file and written a function with this header: logger& operator <<(logger& log, const basic_ostream<char,char_traits<char> >& (*s)(basic_ostream<char,char_traits<char> >&)) But no luck. I've tried the same using templates instead of directly using char, and also tried simply using "const ostream& os", and nothing. Another thing that bugs me is that, in the error output, the first argument for operator<< changes, sometimes it's a reference to a pointer, sometimes looks like a double reference...

  • Acessing a wordpress database from an iPhone App.

    - by Code
    Hi guys, I've been asked to create an app that will get data back from a database where the CMS will be Wordpress. I've never used a CMS so I'm trying to get a (overview)picture in my head of how it could all work and what each of the components would be. And what a CMS actually brings to the party. Creating the app itself is pretty clear. I've done a few already. I've made a database before and shouldnt cause a problem. But what is going to be in the middle between the app and the database? Part A: I'm guessing iphone apps typically would call some php file that's hosted on the server? The php then would make a call to the database and return the data somehow, maybe as xml. But this is really basic and wouldnt require a CMS. Just a database and a phpfile, or am I wrong? Part B: If i wanted to run a check on the database every minute to see if any of the data in database was no longer valid and remove it if needed, that would require somekind of program running on the server. So that program would be Wordpress, since it is managing the content, so a content management system is actually needed and is for these kind of taskes. Am i understanding the role of CMS? Many Thanks, -Code

Any ideas how could the program find the inscision points. Heres my source for the game: > clear; clc; a=1; b=10; x=floor(rand(5,1)*(b-a+1)+a); y=floor(rand(5,1)*(b-a+1)+a); fig1=figure; set(fig1,'Color','w','Position',[100 100 500 500]) plot(x,y,'o','MarkerSize',12,'MarkerFaceColor','r'); axis([0 11 0 11]); axis off grid on; hold on; FirstPlayerLines=[]; SecondPlayerLines=[]; for a1=1:+1:2 for a2=5:-1:2 plot([x(a1) x(a2)],[y(a1) y(a2)],'Color','black','LineWidth',3); end end waitforbuttonpress

  • Best ways to write a method that updates two objects in a multithreaded java environment?

    - by DanielHonig
    Suppose we have a class called AccountService that manages the state of accounts. AccountService is defined as interface AccountService{ public void debit(account); public void credit(account); public void transfer(Account account, Account account1); } Given this definition, what is the best way to implement transfer() so that you can guarantee that transfer is an atomic operation. I'm interested in answers that reference Java 1.4 code as well as answers that might use resources from java.util.concurrent in Java 5

  • JsonIgnore attributes not working in ASP.NET?

    - by Geoffrey
    I've got an object in my project with circular references. I've put [JsonIgnore] above the field like so: [JsonIgnore] public virtual Foobar ChildObject { get; set; } I'm still getting circular reference errors when I serialize the object. The only fields that do not have JsonIgnore are string fields and should not cause this. Is there something else I need to do to get JsonIgnore to work? Thanks!

    I'm looking at the following code block in javascript: var request = new Request(); if(request.Use()) // What exactly does this do? { // ...do stuff } else { // no ajax support? } I've never seen anyone invoke the request.Use() method. My Question: What exactly does request.Use() check? Does it in fact check for AJAX support? Can anyone redirect me to an online API reference?
