  • Where to load a preset dictionary?

    - by cam
    Everytime the program loads, I need a dictionary to have about 15 values. Right now I'm using a function called "Load_Dictionary" that just adds each value. How do you suggest going about loading a dictionary like this? Through a function? Using an XML file?

  • Variables variable and inheritance

    - by Xack
    I made code like this: class Object { function __get($name){ if(isset($this->{$name})){ return $this->{$name}; } else { return null; } } function __set($name, $value){ $this->{$name} = $value; } } If I extend this class (I don't want to repeat this code every time), it says "Undefined variable". Is there any way to do it?

  • Should we use temporary variables for the returned values of functions?

    - by totymedli
    I thought about this: Is there a performance difference in these two practices: Store the return value of a function in a temporary variable than give that variable as a parameter to another function. Put the function into the other function. Specification Assuming all classes and functions are written correctly. Case 1. ClassA a = function1(); ClassB b = function2(a); function3(b); Case 2. function3(function2(function1())); I know there aren't a big difference with only one run, but supposed that we could run this a lot of times in a loop, I created some tests. Test #include <iostream> #include <ctime> #include <math.h> using namespace std; int main() { clock_t start = clock(); clock_t ends = clock(); // Case 1. start = clock(); for (int i=0; i<10000000; i++) { double a = cos(1); double b = pow(a, 2); sqrt(b); } ends = clock(); cout << (double) (ends - start) / CLOCKS_PER_SEC << endl; // Case 2. start = clock(); for (int i=0; i<10000000; i++) sqrt(pow(cos(1),2)); ends = clock(); cout << (double) (ends - start) / CLOCKS_PER_SEC << endl; return 0; } Results Case 1 = 6.375 Case 2 = 0.031 Why is the first one is much slower, and if the second one is faster why dont we always write code that way? Anyway does the second pratice has a name? I also wondered what happens if I create the variables outside the for loop in the first case, but the result was the same. Why?

  • How to re-enable the context menu in this case?

    - by lemonedo
    document.addEventListener('contextmenu', function (e) { e.preventDefault() e.stopPropagation() e.returnValue = false e.cancleBubble = true }) No way? Edit: document.oncontextmenu = null does not work. P.S. I cannot have the reference of the listener function since I am not the owner of the site preventing the context menu.

  • In jQuery, is there any way to only bind a click once?

    - by Chris Henry
    I have an ajax app that will run functions on every interaction. I'd like to be able to run my setup function each time so all my setup code for that function remains encapsulated. However, binding elements more than once means that the handler will run more than once, which is obviously undesirable. Is there an elegant way in jQuery to call bind on an element more than once without the handler being called more than once?

  • Get a char from a CString

    - by Sunscreen
    I have created a function that has as input a char szMyChar; (using it in a switch statement). Now I have a CString havong just a char, lets say CString strString = "A"; An option to call the function could be: if (strString == "A") CallMyFunc('A'); though it is clumsy. I tried atoi (returns 0) and casting though neither works. Any ideas? Thanks, Sun

  • How to pass non-fatal warnings from a library

    - by wRAR
    A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?

    Hi Guys, How do you specify a custom view script for a given Controller Action method? For example: Class UserGalleryController extends Zend_Controller_Action { public function fooAction() { $this->view->actionMsg = 'foo'; // (uses foo.phtml automagically) } public function barAction() { $this->view->actionMsg = 'bar'; //use foo's view script ????? } } I basically want to have one view script (foo.phtml) Thanks :-)

  • Adding an additional click event to every element (JavaScript / jQuery)

    - by Gausie
    I'm developing a touchscreen application that, aside from everything else, records the amount of times the screen is used so that the user can be reminded to clean the screen after a predefined number of clicks. I've got the click functions written nicely, all I need now is make sure the function is called on a click. I imagine $('*').click(function() { //do something }); would accomplish my goal, but is that the best way? Also, would that overwrite other click functions assigned to the elements?

  • Returning and printing string array index in C

    - by user1781966
    I've got a function that searches through a list of names and I'm trying to get the search function to return the index of the array back to the main function and print out the starting location of the name found. Everything I've tried up to this point either crashes the program or results in strange output. Here is my search function: #include<stdio.h> #include<conio.h> #include<string.h> #define MAX_NAMELENGTH 10 #define MAX_NAMES 5 void initialize(char names[MAX_NAMES][MAX_NAMELENGTH], int Number_entrys, int i); int search(char names[MAX_NAMES][MAX_NAMELENGTH], int Number_entrys); int main() { char names[MAX_NAMES][MAX_NAMELENGTH]; int i, Number_entrys,search_result,x; printf("How many names would you like to enter to the list?\n"); scanf("%d",&Number_entrys); initialize(names,Number_entrys,i); search_result= search(names,Number_entrys); if (search_result==-1){ printf("Found no names.\n"); }else { printf("%s",search_result); } getch(); return 0; } void initialize(char names[MAX_NAMES][MAX_NAMELENGTH],int Number_entrys,int i) { if(Number_entrys>MAX_NAMES){ printf("Please choose a smaller entry\n"); }else{ for (i=0; i<Number_entrys;i++){ scanf("%s",names[i]); } } } int search(char names[MAX_NAMES][MAX_NAMELENGTH],int Number_entrys) { int x; char new_name[MAX_NAMELENGTH]; printf("Now enter a name in which you would like to search the list for\n"); scanf("%s",new_name); for(x = 0; x < Number_entrys; x++) { if ( strcmp( new_name, names[x] ) == 0 ) { return x; } } return -1; } Like I mentioned before I have tried a lot of different ways to try and fix this issue, but I cant seem to get them to work. Printing X like what I have above is just the last thing I tried, and therefor know that it doesn't work. Any suggestions on the simplest way to do this?

  • In gzip libary, what's the difference between 'uncompress' and 'gzopen' ?

    - by Sol
    There are some functions to decompress in zlib library(zlib version 1.2.3) I want to decompress my source zip(.gz) file using 'uncompress' function. It is now working(error code -3) but gzopen is. It is still not working when I input payload pointer(passing gzip header) to 'uncompress' . So the question is "What's the valid arguments for uncompress function?" and If it needs different format, how can I make it? Google doesn't helpful this time :(
