  • How to set a value from another class

    - by Ram
    Its said that property should not be "Set" only and it should be "Get" as well. What should i do if I need to set value to a variable from some other class? The will keep changing so I cannot pass it through constructor. Shall I create a function for this as shown below? class A { public void SetValue() { b = new B(); b.SetTest(10); } } class B { int test; public void SetTest(int value) { test = value; } } What are the other alternatives?

  • [PHP] Variables loaded from a separate script are not defined within functions

    - by Goro
    Hello, I use settings.php to store general settings for my application. When I load this settings file, I can use the variables defined in settings.php in the script itself, but not within any functions I define in it. For example, in my class definition, myclass.php: <?php $preIP = dirname(__FILE__); require_once( "preIP/settings.php" ); class MyClass { ... public function foo() { echo $variable_from_settings; } } The code in the function foo() will not work (the variable will not be defined). The settings.php file looks like this: $variable_from_settings = "bar"; Thanks,

  • Why does GC.GetTotalMemory() report huge memory allocations?

    - by Seventh Element
    I have been playing around with GC.GetTotalMemory(). When I create a local variable of type Titles in the example below, the consumed amount of memory increases by 6276 bytes. What's going on here? class Program { enum Titles { Mr, Ms, Mrs, Dr }; static void Main(string[] args) { GetTotalMemory(); Titles t = Titles.Dr; GetTotalMemory(); } static void GetTotalMemory() { long bytes = GC.GetTotalMemory(true); Console.WriteLine("{0}", bytes); } }

  • Sorting a listview (Win32/C++)

    - by Zenox
    I'm trying to sort a listview when the user clicks on the column header. I am catching the LVN_COLUMNCLICK notification like so: case LVN_COLUMNCLICK: { NMLISTVIEW* pListView = (NMLISTVIEW*)lParam; BOOL test = ListView_SortItems ( m_hDuplicateObjectsList, ListViewCompareProc, pListView->iSubItem ); break; } However it seems to fail. My test variable is FALSE and my ListViewCompareProc never gets hit (it has a simple return 1 while I am trying to hit a debug point inside of it). Is there something I am missing for sorting a listview?

  • What's wrong with this Perl 'grep' syntax?

    - by wes
    I've got a data structure that is a hash that contains an array of hashes. I'd like to reach in there and pull out the first hash that matches a value I'm looking for. I tried this: my $result = shift grep {$_->{name} eq 'foo'} @{$hash_ref->{list}}; But that gives me this error: Type of arg 1 to shift must be array (not grep iterator). I've re-read the perldoc for grep and I think what I'm doing makes sense. grep returns a list, right? Is it in the wrong context? I'll use a temporary variable for now, but I'd like to figure out why this doesn't work.

  • Why can't I project ToString() in VB?

    - by Martinho Fernandes
    If you try to compile the query below in Visual Basic .NET, it fails. From x In {1, 2} Select x.ToString() The error given by the compiler is: Range variable name cannot match the name of a member of the 'Object' class. There is nothing wrong with the equivalent C# query, though: from x in new[]{1, 2} select x.ToString() This does not happen with the ToString overload that takes a format (it is a member of Int32, not Object). It does happen with other members of Object, as long as they don't take an argument: with GetType and GetHashCode it fails; with Equals(object) it compiles. Why is this restriction in place, and what alternatives can I use?

  • Is it possible to apply NOT(!) operator while DataBinding a property of a control ?

    - by Ashish Ashu
    I have Button control and I have to set the IsEanbled property based on the bool variable. bool IsBoolVariable I want if IsBoolVariable property is true then I want to set the IsEnabled property to false AND when IsBoolVariable property is false then I want to set the IsEnabled property to true. Is it possible to apply not(!) operator while defining the binding as given below <Button IsEnabled = "{Binding Path = **!**IsBoolVariable}" /> I can very well do that by applying convertors , but that is the only way to do that?

  • Javascript if/else statement in iframe

    - by gr33nh4t
    So I'm trying to use javascript to pop up a video, and need to know when I'm in an iframe so I can resize the video accordingly. When outside the iframe, I see three alerts ('this is seen by both', 'not in iframe', and 'this is after the fact') When in the iframe, I just see the first alert ('this is seen by both'). var handleViewVideoClick = function (dataAction, eventType, targetElement, dataActionElement) { alert('this is seen by both'); if ($('iframe', window.parent.document).length == 0) { alert('not in iframe'); } else { alert('in iframe'); } alert('this is after the fact...'); }; What's going on here?

  • Is there a way to get a reference to all the paragraphs or headings in a web page in JavaScript?

    - by mattbd
    I'm writing a simple Greasemonkey script to strip out all the images, headings and paragraphs from a web page (it's because someone wants to use images of several popular websites with the images and text removed in a presentation about branding of websites). I've figured out how to do so with images by using a for loop and the document.images array like this: var i = 0; var imglngth = document.images.length; for(i=0;i<imglngth;i++) { document.images[i].style.display="none"; } However, I don't believe there's an object representing paragraphs or headers. Any suggestions as to how I could implement this?

  • g++: how to specify preference of library path?

    - by Heinrich Schmetterling
    I'm compiling a c++ program using g++ and ld. I have a .so library I want to be used during linking. However, a library of the same name exists in /usr/local/lib, and ld is choosing that library over the one I'm directly specifying. How can I fix this? For the examples below, my library file is /my/dir/libfoo.so.0. Things I've tried that don't work: my g++ command is "g++ -g -Wall -o my_binary -L/my/dir -lfoo bar.cpp" adding /my/dir to the beginning or end of my $PATH env variable adding /my/dir/libfoo.so.0 as an argument to g++ Thanks.

  • Switching from php to python

    - by ts
    Hello I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python. so far i have rather short list: forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem) you can't just upload file on server to have webpage (-mod_python, wsgi etc) learn the python way for use variable class names (new $class() vs import + getattr) / operator in python 2.x and all float-related horrors those were difficult to me, it takes few days before mind adapts a new paradigm after i found that there is few other areas which could be challenging for someone with (too) many years of php: everything is an object you have to live with exceptions array vs list, set, dictionary, tuple ... learn (effective) list comprehensions learn generators any other ideas / personal experiences ?

  • Changing the context of a self-executing function

    - by TaylorMac
    This code is copied directly from: http://www.bennadel.com/blog/2264-Changing-The-Execution-Context-Of-Your-Self-Executing-Function-Blocks-In-JavaScript.htm // Set the singleton value to the return value of the self- // executing function block. var singleton = (function(){ // Declare a private variable. var message = "Stop playing with your context!"; this.getMessage = function(){ return( message ); }; // Return this object reference. return( this ); }).call( {} ); // alert the singleton message. alert( "Message:", singleton.getMessage()); ?My thought is that I can use this to better contain the variables and functions in my programs. However, when I try to run the code in a JSfiddle: http://jsfiddle.net/xSKHh/ It does not return the message. What am I missing?

  • Subtype polymorphism and arrays

    - by user133466
    Computer[] labComputers = new Computer[10]; with public class Computer { ... void toString(){ // print computer specs } } public class Notebook extends Computer{ ... void toString(){ // print computer specs + laptop color } } each subscripted variable labComputers[i] can reference either a Computer object or a Notebook object because Notebook is a subclass of Computer. For the method call labComputers[i].toString(), polymorphism ensures that the correct toString method is called. I wonder what if we do Notebook[] labComputers = new Notebook[10]; what kind or error would I get if I reference with Computer object and a Notebook object

    - by Alonzo
    Hi What im trying to do is that when the esc key is pressed on the text input field (id = txtSearch), some code will run. this is my code: $(document).ready(function() { $('#txtSearch').bind('keyup', function(e) { var characterCode; // literal character code will be stored in this variable if (e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; } else { characterCode = e.keyCode; } if (characterCode == 27) //if esc key { //do stuff } }); } It doesnt work for me. however, if i would change that line: $('#txtSearch').bind('keyup', function(e) { with: $(document).bind('keyup', function(e) { everything works. but i dont want to bind the keyup with esc to the whole document... any suggestions on how i can bind the the keyup only with the specific text search element? (or its containing div or something) Thanks!

  • Same memory space being allocated again & again while using malloc()

    In each loop iteration, variable j is declared again and again. Then why is its address remaining same? Shouldn't it be given some random address each time?

  • How to arrange labels in a flowlayout manner?

    - by Tim Büthe
    How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

  • how to use constants in SQL CREATE TABLE?

    - by kchiu
    Hi, I have 3 SQL tables, defined as follows: CREATE TABLE organs( abbreviation VARCHAR(16), -- ... other stuff ); CREATE TABLE blocks( abbreviation VARCHAR(16), -- ... other stuff ); CREATE TABLE slides( title VARCHAR(16), -- ... other stuff ); The 3 fields above all use VARCHAR(16) because they're related and have the same length restriction. Is there a (preferably portable) way to put '16' into a constant / variable and reference that instead in CREATE TABLE? eg. something like this would be nice: CREATE TABLE slides( title VARCHAR(MAX_TITLE_LENGTH), -- ... other stuff ); I'm using PostgreSQL 8.4. thanks a lot, and Happy New Year! cheers.

  • Is void *p = 0L valid?

    - by Artefacto
    In this answer, sassman initializes a pointer with: zend_class_entry* ce = 0L; My question is – is this valid? I would say it isn't, to initialize the variable with a null pointer either an unadorned (and possibly casted to void *) 0 constant, or some macro that evaluates to that such as NULL should be used. However, I can't find definitive language in the standard that supports this interpretation. All it says is: An integer constant expression with the value 0, or such an expression cast to type void *, is called a null pointer constant.
