  • How to declare a function that accepts a lambda?

    - by Andreas Bonini
    I read on the internet many tutorials that explained how to use lambdas with the standard library (such as std::find), and they all were very interesting, but I couldn't find any that explained how I can use a lambda for my own functions. For example: int main() { int test = 5; LambdaTest([&](int a) { test += a; }); return EXIT_SUCCESS; } How should I declare LambdaTest? What's the type of its first argument? And then, how can I call the anonymous function passing to it - for example - "10" as its argument?

  • How do I apply a string function to an array?

    - by ggg
    I was fortunate enough to receive this code (flips Lastname, Firstname) from an earlier post. $name = "Lastname, Firstname"; $names = explode(", ", $name); $name = $names[1] . " " . $names[0]; How do I apply the function to each value in an array that is in the form: $ginfo ->$(LastName, FirstName). I tried the code below, but it doesn't work. $name1 =($ginfo->White); $name1 = explode(", ", $name1); $FLw = $name1[1] . " " . $name1[0]; foreach ($name1 as ($ginfo->White)) {return($FLw);}

  • Efficient implementation of threads in the given scenario

    - by shadeMe
    I've got a winforms application that is set up in the following manner: 2 buttons, a textbox, a collection K, function X and another function, Y. Function X parses a large database and enumerates some of its data in the global collection. Button 1 calls function X. Function Y walks through the above collection and prints out the data in the textbox. Button 2 calls function Y. I'd like to call function X through a worker thread in such a way that: The form remains responsive to user input. This comes intrinsically from the use of a separate thread. There is never more than a single instance of function X running at any point in time. K can be accessed by both functions at all times. What would be the most efficient implementation of the above environment ?

  • define a closure as method from class

    - by user272839
    Hi, i'm trying to play with php5.3 and closure. I see here (Listing 7. Closure inside an object : http://www.ibm.com/developerworks/opensource/library/os-php-5.3new2/index.html) that it's possible to use $this in the callback function, but it's not. So I try to give $this as use variable : $self = $this; $foo = function() use($self) { //do something with $self } So to use the same example : class Dog { private $_name; protected $_color; public function __construct($name, $color) { $this->_name = $name; $this->_color = $color; } public function greet($greeting) { $self = $this; return function() use ($greeting, $self) { echo "$greeting, I am a {$self->_color} dog named {$self->_name}."; }; } } $dog = new Dog("Rover","red"); $dog->greet("Hello"); Output: Hello, I am a red dog named Rover. First of all this example does not print the string but return the function, but that's not my problem. Secondly I can't access to private or protected, because the callback function is a global function and not in the context from the Dog object. Tha't my problem. It's the same as : function greet($greeting, $object) { echo "$greeting, I am a {$self->_color} dog named {$self->_name}."; } And I want : public function greet($greeting) { echo "$greeting, I am a {$self->_color} dog named {$self->_name}."; } Which is from Dog and not global. I hope that I am clear ...

  • How do you write an idiomatic Scala Quicksort function?

    - by Don Mackenzie
    I recently answered a question with an attempt at writing a quicksort function in scala, I'd seen something like the code below written somewhere. def qsort(l: List[Int]): List[Int] = { l match { case Nil => Nil case pivot::tail => qsort(tail.filter(_ < pivot)) ::: pivot :: qsort(tail.filter(_ >= pivot)) } } My answer received some constructive criticism pointing out that List was a poor choice of collection for quicksort and secondly that the above wasn't tail recursive. I tried to re-write the above in a tail recursive manner but didn't have much luck. Is it possible to write a tail recursive quicksort? or, if not, how can it be done in a functional style? Also what can be done to maximise the efficiency of the implementation? Thanks in advance.

  • In C, as free() knows an array size, why isn't there a function that gets the array size? [closed]

    - by user354959
    Possible Duplicate: If free() knows the length of my array, why can’t I ask for it in my own code? Searching around (including here at stackoverflow), I got that malloc() allocates an array and also creates a header to control the array info. In this header, there's also the array size. free() use such information to know how to deallocate that array. So, if the array size info is "there" (somewhere in the memory), why there isn't a function that returns an array size, looking for this at the array header? Or am I missing something?

  • Passing variables to functions in Python

    - by brno792
    Im writing test scripts in python for selenium web testing. How do I pass parameters through a python function to call in a later function? I first have a login test function. Then I have a new user registration function. Im trying to pass the Username and Password I use in the registration function to the testLogin function that I call inside the testRegister function. This is my python code: userName = "admin" password = "admin" #pass username and password variables to this function def testLogin(userName,password): browser = webdriver.Firefox() browser.get("http://url/login") element = browser.find_element_by_name("userName") element.send_keys(userName) element = browser.find_element_by_name("userPassword") element.send_keys(password) element.send_keys(Keys.RETURN) browser.close() # test registration def testRegister(): browser = webdriver.Firefox() browser.get("http://url/register") #new username variable newUserName = "test" element = browser.find_element_by_name("regUser") element.send_keys(newUserName) #new password variable newUserPassword = "test" element = browser.find_element_by_name("regPassword") element.send_keys(newUserPassword) # #now test if user is registered, I want to call testLogin with the test user name and pw. testLogin(newUserName,newUserPassword) browser.close()

  • Does a static object within a function introduce a potential race condition?

    - by Jeremy Friesner
    I'm curious about the following code: class MyClass { public: MyClass() : _myArray(new int[1024]) {} ~MyClass() {delete [] _myArray;} private: int * _myArray; }; // This function may be called by different threads in an unsynchronized manner void MyFunction() { static const MyClass _myClassObject; [...] } Is there a possible race condition in the above code? Specifically, is the compiler likely to generate code equivalent to the following, "behind the scenes"? void MyFunction() { static bool _myClassObjectInitialized = false; if (_myClassObjectInitialized == false) { _myClassObjectInitialized = true; _myClassObject.MyClass(); // call constructor to set up object } [...] } ... in which case, if two threads were to call MyFunction() nearly-simultaneously, then _myArray might get allocated twice, causing a memory leak? Or is this handled correctly somehow?

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

  • Applying a function with multiple inputs using Map? (Haskell)

    - by Schroedinger
    G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

  • Implicit declaration when using a function before it is defined in C, why can't the compiler figure this out?

    - by rolls
    As the title says, I know what causes this error but I want to know why the compiler gives it in this circumstance. Eg : main.c void test(){ test1(); } void test1(){ ... } Would give an implicit declaration warning as the compiler would reach the call to test1() before it has read its declaration, I can see the obvious problems with this (not knowing return type etc), but why can't the compiler do a simple pass to get all function declarations, then compile the code removing these errors? It just seems so simple to do and I don't believe I've seen similar warnings in other languages. Does anyone know if there is a specific purpose for this warning in this situation that I am overlooking?

  • How do I use "this" in a member function?

    - by Peter Stewart
    I've written a member function of class Node to read a tree of Nodes in postfix order. It will be called by the Node instance which is the root node of the tree. So: N.postfix(); these appear to be illeagal: *this->left.postfix(); *this->right.postfix(); What is the proper way to do this? class Node { public: const char *cargo; int depth; Node *left; Node *right void Node::postfix() { if (this==__nullptr) { return; } else { *this->left.postfix(); *this->right.postfix(); out<<*this->cargo<<"\n"; return; } };

How can I make ColPeekHeight() an l-value?

  • Occurs in MYOB Accounting Plus 18.5 among other versions. Cannot get the function address for " MAPI

    - by sjw
    I've installed MYOB on SBS server 2003. Why? Because the users were using offline files and it turned out there was about 7 versions of the file both locally and on the server that were out of sync... So the only way I could control the file access was to force RDP to the server... Always using the server file and always in sync... Anyway, this issue occurs in MYOB Accounting Plus 18.5. Cannot get the function address for "MAPISendMail" from "MAPI32.dll" Please check your Mapi installation I just want to send mail from MYOB but I can't - MYOB support is useless and blames everyone else...(i.e. Microsoft and outlook) I have found other people with the same problem whose resolution appears to be to copy MAPI32.dll into myob directory but that hasn't worked for me...

  • How to pass a class method as an argument for another function in C++ and openGL?

    - by tsubasa
    I know this thing works: void myDisplay() { ... } int main() { ... glutDisplayFunc(myDisplay) ... } so I tried to include myDisplay() function to a class that I made. Because I want to overload it in the future with a different class. However, the compiler complains that argument of type 'void (ClassBlah::)()' does not match 'void(*)()' . Here is the what I try to make: class ClassBlah { .... void myDisplay() .... } ...... int main() { ... ClassBlah blah glutDisplayFunc(blah.myDisplay) ... } Does anybody knows how to fix this problem? Many thanks.

  • What does this PHP (function/construct?) do, and where can I find more documentation on it?

    Simple question. Here is this code. $r = rand(0,1); $c = ($r==0)? rand(65,90) : rand(97,122); $inputpass .= chr($c); I understand what it does in the end result, but I'd like a better explanation on how it works, so I can use it myself. Sorry if this is a bad question. If you're unsure of what I'm asking about, its the (function?) used here: $c = ($r==0)? rand(65,90) : rand(97,122);

  • jQuery: How to stop propagation of a bound function not the entire event?

    - by Dale
    I have a click function bound to many elements. It is possible that sometimes these elements may sit within one another. So, the click event is bound to a child and also bound to its parent. The method is specific to the element clicked. Naturally, because of event bubbling, the child's event is fired first, and then the parents. I cannot have them both called at the same time because the parents event overwrites the event of the child. So I could use event.stopPropagation() so only the first element clicked receives the event. The problem is that there are other click events also attached to the element, for example, I am using jQuery's draggable on these elements. If I stop the propagation of the click event, then draggable doesn't work, and the following click events are not called. So my question is: Is there a way to stop the event bubbling of the method the event will call and not the entire event?

  • Pass in a value into Python Class through command line

    - by chrissygormley
    Hello, I have got some code to pass in a variable into a script from the command line. The script is: import sys, os def function(var): print var class function_call(object): def __init__(self, sysArgs): try: self.function = None self.args = [] self.modulePath = sysArgs[0] self.moduleDir, tail = os.path.split(self.modulePath) self.moduleName, ext = os.path.splitext(tail) __import__(self.moduleName) self.module = sys.modules[self.moduleName] if len(sysArgs) > 1: self.functionName = sysArgs[1] self.function = self.module.__dict__[self.functionName] self.args = sysArgs[2:] except Exception, e: sys.stderr.write("%s %s\n" % ("PythonCall#__init__", e)) def execute(self): try: if self.function: self.function(*self.args) except Exception, e: sys.stderr.write("%s %s\n" % ("PythonCall#execute", e)) if __name__=="__main__": test = test() function_call(sys.argv).execute() This works by entering ./function <function> <arg1 arg2 ....>. The problem is that I want to to select the function I want that is in a class rather than just a function by itself. The code I have tried is the same except that function(var): is in a class. I was hoping for some ideas on how to modify my function_call class to accept this. Thanks for any help.
