  • Removing Duplicates in an array in C

    - by LuckySlevin
    The question is a little complex. The problem here is to get rid of duplicates and save the unique elements of array into another array with their original sequence. For example : If the input is entered b a c a d t The result should be : b a c d t in the exact state that the input entered. So, for sorting the array then checking couldn't work since I lost the original sequence. I was advised to use array of indices but I don't know how to do. So what is your advise to do that?

  • Real world examples of Ecmascript functions returning a Reference?

    - by Bergi
    Read the EcmaScript specification, section 8.7 The Reference Specification Type: The Reference type is used to explain the behaviour of such operators as delete, typeof, and the assignment operators. […] A Reference is a resolved name binding. Function calls are permitted to return references. This possibility is admitted purely for the sake of host objects. No built-in ECMAScript function defined by this specification returns a reference and there is no provision for a user-defined function to return a reference. Those last two sentences impressed me. With this, you could do things like coolHostFn() = value (valid syntax, btw). So my question is: Are there any EcmaScript implementations that define host function objects which result in Reference values?

I want the columns to be side by side not in one column

  • Can a rake task know about the other tasks in the invocation chain?

    - by andrewdotnich
    Rake (like make) is able to have many targets/tasks specified on invocation. Is it possible for a rake task to access the list of tasks the user invoked, in order to do its job? Scenario: Consider a Rake-based build tool. A help task would like to know what tasks were also specified in order to print their usage and halt the build process. The benefit of this as opposed to rake-style parameter passing are cleaner syntax (rake help build instead of rake help task=build) and chaining (rake help build run_tests would print usage for both).

  • file_operations Question, how do i know if a process that opened a file for writing has decided to c

    - by djTeller
    Hi Kernel Gurus, I'm currently writing a simple "multicaster" module. Only one process can open a proc filesystem file for writing, and the rest can open it for reading. To do so i use the inode_operation .permission callback, I check the operation and when i detect someone open a file for writing I set a flag ON. i need a way to detect if a process that opened a file for writing has decided to close the file so i can set the flag OFF, so someone else can open for writing. Currently in case someone is open for writing i save the current-pid of that process and when the .close callback is called I check if that process is the one I saved earlier. Is there a better way to do that? Without saving the pid, perhaps checking the files that the current process has opened and it's permission... Thanks!

  • Enums With Default Throw Clause?

    - by Tom Tresansky
    I noticed the following in the Java Language spec in the section on enumerations here: link switch(this) { case PLUS: return x + y; case MINUS: return x - y; case TIMES: return x * y; case DIVIDE: return x / y; } throw new AssertionError("Unknown op: " + this); However, looking at the switch statement definition section, I didn't notice this particular syntax (the associated throw statement) anywhere. Can I use this sort of "default case is throw an exception" syntactic sugar outside of enum definitions? Does it have any special name? Is this considered a good/bad practice for short-cutting this behavior of "anything not in the list throws an exception"?

  • Encrypting password in compiled C or C++ code

    - by Daniel
    Hello!, I know how to compile C and C++ Source files using GCC and CC in the terminal, however i would like to know if its safe to include passwords in these files, once compiled. For example.. i check user input for a certain password e.g 123, but it appears compiled C/C++ programs is possible to be decompiled. Is there anyway to compile a C/C++ source file, while keeping the source completely hidden.. If not, could anyone provide a small example of encrypting the input, then checking against the password e.g: (SHA1, MD5)

  • How to check for undefined or null variable in javascript

    - by Thomas Wanner
    We are frequently using the following code pattern in our javascript code if(typeof(some_variable) != 'undefined' && some_variable != null) { // do something with some_variable } and I'm wondering whether there is a less verbose way of checking that has the same effect. According to some forums and literature saying simply if(some_variable) { // do something with some_variable } should have the same effect. Unfortunately, Firebug evaluates such a statement as error on runtime when some_variable is undefined, whereas the first one is just fine for him. Is this only an (unwanted) behavior of Firebug or is there really some difference between those two ways ?

  • Count down timer

    - by Ohmnastrum
    I have a timer set up and it gets called when ever the player is in their turn phase. I also have a multiplier that decrements slowly while the player is committing actions. for some odd reason my mult variable is returning garbage values I initialized it to 1 in the onLoad statement but it still seems to have trouble. -(void) Timerbar:(NSTimer *)barTimer { if(!waitForPlayer) { [barTimer invalidate]; } if(mult > 0.0) { mult -= 0.01; if(mult < 0) { mult = 0; } } power = (mult * 10) / pwrBarMaxWidth; pwrBarWidth = (int)power % limit; NSLog(@"%d", mult); } Do I have a syntax error somewhere?

  • Knowing the fundamentals of Java what is the right approach to learn Groovy?

    - by Liuh
    As my question already implies I want to learn a new language and have read several articles about groovy and its more pragmatic syntax. SO I have choosen Groovy as the language of my choice. What is a good way to learn a new language like Groovy when I already know the fundamentals of Java. When I understand correctly Groovy will be running in the Java Virtual Machine and allows me to always rely on what I know from Java when I don't know how to solve the problem in Groovy. I am looking for hints on how to organize a learning track to learn this language. I found that page explaining the differences: http://groovy.codehaus.org/Differences+from+Java But what I am looking for is more a tutorial where I can get through and get introduced to the differences.

  • Help with python list-comprehension

    - by leChuck
    A simplified version of my problem: I have a list comprehension that i use to set bitflags on a two dimensional list so: s = FLAG1 | FLAG2 | FLAG3 [[c.set_state(s) for c in row] for row in self.__map] All set_state does is: self.state |= f This works fine but I have to have this function "set_state" in every cell in __map. Every cell in __map has a .state so what I'm trying to do is something like: [[c.state |= s for c in row] for row in self.map] or map(lambda c: c.state |= s, [c for c in row for row in self.__map]) Except that neither works (Syntax error). Perhaps I'm barking up the wrong tree with map/lamda but I would like to get rid on set_state. And perhaps know why assignment does not work in the list-comprehension

  • C# VS 2008 Build Configurations - using different classes for different builds

    - by evan
    I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!

  • ServiceBus WorkerRole DiagnosticMonitor Error

  • Which file is the COM++ object and how do I import it to .NET?

    - by Bad Man
    I'm trying to write a COM++ object wrapper around a Qt widget (control) I wrote so I can use it in future .NET projects. e.g.: public __gc class comWidget; In the compile directory are the .exe, an exe.intermediate.manifest, and the comWidget.obj, and also some other crap files (.pdb, etc). So what/how do I import into .NET? I feel like I'm missing an important step for registering the object or whatever, but all these tutorials are terrible outdated and ridiculously unhelpful (for instance, I'm using the old CLR syntax because I can't find any good docs on the new stuff, thx again M$ for being lazy faggots as usual)

  • Custom constructors for models in Google App Engine (python)

    - by Nikhil Chelliah
    I'm getting back to programming for Google App Engine and I've found, in old, unused code, instances in which I wrote constructors for models. It seems like a good idea, but there's no mention of it online and I can't test to see if it works. Here's a contrived example, with no error-checking, etc.: class Dog(db.Model): name = db.StringProperty(required=True) breeds = db.StringListProperty() age = db.IntegerProperty(default=0) def __init__(self, name, breed_list, **kwargs): db.Model.__init__(**kwargs) self.name = name self.breeds = breed_list.split() rufus = Dog('Rufus', 'spaniel terrier labrador') rufus.put() The **kwargs are passed on to the Model constructor in case the model is constructed with a specified parent or key_name, or in case other properties (like age) are specified. This constructor differs from the default in that it requires that a name and breed_list be specified (although it can't ensure that they're strings), and it parses breed_list in a way that the default constructor could not. Is this a legitimate form of instantiation, or should I just use functions or static/class methods? And if it works, why aren't custom constructors used more often?

  • C++: Why does space always terminate a string when read?

    - by Nullw0rm
    Using type std::string to accept a sentence, for practise (I haven't worked with strings in C++ much) I'm checking if a character is a vowel or not. I got this: for(i = 0; i <= analyse.length(); i++) { if(analyse[i] == 'a' || analyse[i] == 'e' [..etc..]) { ...vowels++; } else { ... ...consenents++; } This works fine if the string is all one word, but the second I add a space (IE: aeio aatest) it will only count the first block and count the space as a consenent, and quit reading the sentence (exiting the for loop or something). Does a space count as no character == null? Or some oddity with std::string?, It would be helpful to know why that is happening!

  • Server-side Javascript (aspx.cs) Attributes.Add Code to Change a Label's text

    - by DFM
    I am trying to change a label's text by using server-side javascript (onclick) and C# within the page_load event. For example, I would like to write something like the following: Label1.Attributes.Add("onclick", "Label2.text='new caption'") Does anyone know the correct code for this? Also, what is this type of code referred to; is it just javascript or javascript in C# or is there a specific name? Lastly, does a book or online resource exist that lists the choices of control.attributes.add("event", "syntax") code to use with C#? Thank you, DFM

  • Is there a way to make XmlDocument parsing less strict

    - by Istrebitel
    I am making a program that will store its data in an XML file. When people write XML they can make subtle mistakes, like ending a comment with - so it looks like <!-- comment ---> or adding a </>inside an attribute. Naturally, the XML still can be read all right, but trying to input this text into XmlDocument will give a syntax error (and it wont be parsed). Is there a way to make XmlDocument less strict and make it ignore violations of the standard that do not make the document unparseable? For example, its clear that <!-- comment ---> is still a comment even though it contains - at the end which is against the standard specification).

  • Closing a window when it's "no longer needed".

    - by Mason Blier
    This is kind of a hard question to describe, and I've searched for about an hour now to no avail. Essentially, picture a small 'flyout' window like the Windows 7 Wireless Control or the Volume Slider from the system tray(notification area). When you click on the icon, the application pops up with focus, and if you click off of it, the window destroys itself. I thought it woudl be easily solved by simply having my window destroy it self when it loses focus (I've been listening for WM_KILLFOCUS), but the problem is, if the icon is clicked, my window does not always get focus. Since this isn't the case, if the user clicks my icon, and then clicks away because it was a mistake (on the desktop say), then how can I set my app to close? I've tried messing with SPY++ but checking the volume control / wireless control apps are proving difficult as they disappear when I try to get their window/process handles. Thanks!

  • Function not recognized from jQuery

    - by coffeeaddict
    I've got a .js file that has this function in it: function showDialog(divID) { var dialogDiv = $(divID); dialogDiv.dialog ( { bgiframe: true, modal: true, autoOpen: false, show: 'blind' } ) And in my page this: <script type="text/javascript"> $(function() { $("input.invokeDialog").click.showDialog("#testDialog"); }); </script> I'm trying to figure out why it doesn't recognize my showDialog function. Is it not possible to reference it with the dot as I am doing? Do I need a jQuery specific function or syntax for it to know that it's a jQuery function or is there no such thing?

  • Android: Best way/library to write an app that simply gets/sets your Facebook status, sends Facebook

    - by D.
    I have the Android Facebook-Connect library running in my emulator and I'm able to set my status with the Facebook API I have setup. However, I don't know where to go from there? Am I supposed to use the session key that this library allows me to get and make some Facebook API calls? I haven't found any code examples to even see what the proper syntax is. Am I better off using another library? I tried fbrocket with limited luck(I get a "server error 104 - Incorrect signature"). Thanks for any help.

  • C++: Can a macro expand "abc" into 'a', 'b', 'c'?

    - by Peter Alexander
    I've written a variadic template that accepts a variable number of char parameters, i.e. template <char... Chars> struct Foo; I was just wondering if there were any macro tricks that would allow me to instantiate this with syntax similar to the following: Foo<"abc"> or Foo<SOME_MACRO("abc")> or Foo<SOME_MACRO(abc)> etc. Basically, anything that stops you from having to write the characters individually, like so Foo<'a', 'b', 'c'> This isn't a big issue for me as it's just for a toy program, but I thought I'd ask anyway.

  • How to count new lines in Internet Explorer?

    - by Impirator
    Hey, all. I'm doing my own syntax highlighter for Javascript and CSS, and I've run into an issue with Internet Explorer (big surprise). I grab all the contents of a code.block tag (example below) using innerHTML, and .split("\n") that result to get each line by itself. This works wonderfully except in IE. I have tried using innerText and .split("\r\n") also without success. Can anyone recommend a solution? If it makes a difference, my code.block tags are styled to be white-space:pre-wrap. <code class="block css">div#randomBarsDemo { width:175px; height:200px; } div#randomBarsDemo div { background-color:#111; width:100%; }</code>

  • Firefox HTML5 video playback inconsistancy

    - by Daniel Redwood
    Hey all, I've got an HTML5 video on a page. When tested locally, Chrome, Safari, and Opera work beautifully. Firefox plays it, but doesn't loop as efficiently as the others. The real problem is when it's tested off a server. Firefox doesn't play the video, but recognizes there is one there. I was wondering if all that open ended three-different-ways syntax can be swung in Firefox's favor. Thanks! HTML: <video id="vid_home" width="780" height="520" autoplay="autoplay" loop="loop"> <source src="Video/fernando.ogv" type="video/ogg" /> <source src="Video/fernando.m4v" type="video/mp4" /> Your browser does not support this videos playback. </video>
