• How can I work around the fact that in C++, sin(3.14159265) is not 0?

  - by Adam Doyle

  In C++, const double Pi = 3.14159265; cout << sin(Pi); // displays: 3.58979e-009 it SHOULD display the number zero I understand this is because Pi is being approximated, but is there any way I can have a value of Pi hardcoded into my program that will return 0 for sin(Pi)? (a different constant maybe?) In case you're wondering what I'm trying to do: I'm converting polar to rectangular, and while there are some printf() tricks I can do to print it as "0.00", it still doesn't consistently return decent values (in some cases I get "-0.00") The lines that require sin and cosine are: x = r*sin(theta); y = r*cos(theta); BTW: My Rectangular - Polar is working fine... it's just the Polar - Rectangular Thanks! edit: I'm looking for a workaround so that I can print sin(some multiple of Pi) as a nice round number to the console (ideally without a thousand if-statements)

• How do I properly load the jQuery fullcalendar plugin in a hidden div

  - by Jens Alm

  I'm using the jQuery tools tabs to divide my page into tabs. One of those tabs contain a jQuery Fullcalendar. Because I load JavaScript last in the page for speed and to avoid flash of unstyled content, I hide the initially unseen tabs using display:none. When doing this, the fullcalendar doesn't render properly. It shows the proper buttons, but until I press the today-button, no calendar is shown. If I allow it to render into a visible div, it displays properly. I can work around this using the tab-select events to render the calendar or by moving the calendar and tab scripts to the head, but I'd rather if there was a more proper solution.

• How to use xcode compiler warnings to determine minimum IOS deployment target

  - by Martin Bayly

  I'm building an iOS app using Xcode 3.2.5 with the Base SDK set to iOS 4.2 I know I've used some api's from 4.0 and 4.1 but not sure about whether I actually require 4.2. According to the iOS Development Guide, "Xcode displays build warnings when it detects that your application is using a feature that’s not available in the target OS release". So I was hoping to use the compiler warnings to derive my minimum OS requirement. However, even when I set my iOS Deployment Target to iOS 3.0, I still don't get any compiler warnings. I must be doing something wrong, but not sure what? Can anyone confirm that they get compiler warnings when the iOS deployment target is less than the base SDK and the code uses base SDK functions? Or do the compiler warnings only show if you link a framework that didn't exist in the iOS deployment target version?

• Views jump during ViewDidLoad

  - by Jon-Paul

  Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

• Reducing decimal places in Delphi

  - by Hendriksen123

  I am storing a list of numbers (as Double) in a text file, then reading them out again. When I read them out of the text file however, the numbers are placed into the text box as 1.59993499 for example, instead of 1.6. AssignFile(Pipe, 'EconomicData.data'); Reset(Pipe); For i := 1 to 15 Do ReadLn(Pipe, SavedValue[i]); CloseFile(Pipe); Edit1.Text := FloatToStr(SavedValue[1]); The text in Edit1.text, from the code above, would be 1.59999... instead of the 1.6 in the text file. How can i make it so the text box displays the original value (1.6)?

• C# Button Text Unicode characters.

  - by Fossaw

  C# doesn't want to put Unicode characters on buttons. If I put \u2129 in the Text attribute of the button, the button displays the \u2129, not the Unicode character, (example - I chose 2129 because I could see it in the font currently active on the machine). I saw this question before, link text, but the question isn't really answered, just got around. I am working on applications which are going all over the world, and don't want to install all the fonts, more then "don't want", there are that many that I doubt the machine I am working on has sufficient disk space. Our overseas sales agents supply the Unicode character "numbers". Is there another way forward with this? As an aside, (curiosity), why does it not work?

• webkit multiple inline shadows

  - by meo

  I have trouble setting multiple shadows on one element in webkit: -moz-box-shadow: inset 0 0 3px #999, 0 0 5px #fff; -webkit-box-shadow: inset 0 0 3px #999, 0 0 5px #fff; box-shadow: inset 0 0 3px #999, 0 0 5px #fff; it works fine in firefox but safari displays only the inset shadow. i tried to set both values separately. But safari takes just count of the last value: -webkit-box-shadow: inset 0 0 3px #999; -webkit-box-shadow: 0 5px #fff; is it possible to set more then one shadow on a single element in safari/webkit?

• Why is Visual Studio 2008 slow with Firefox?

  - by Edward Tanguay

  I am using Microsoft Visual Web Developer 2008 Express. I've made an ASP.NET MVC site which has 6 CSS files and 6 Javascript files in the HEAD element in the Site.Master file. When I do F5 or CTRL-F5 in Explorer or Opera, the site displays instantly. When I run my site in Firefox, it takes a SECOND for each CSS and each Javascript file on LOCALHOST, i.e. 12 seconds to load on localhost. What might I be able to change in the Firefox settings so it is as fast as Opera and Explorer? NEW INFO: Uninstalled Firebug completely, no yslow, no other add-ons. When I take out the CSS and Javascript files, then Firefox is as fast as the other browsers. What could be taking it so long on a local connection?

• Can you decode a mutable Bitmap from an InputStream?

  - by Daniel Lew

  Right now I've got an Android application that: Downloads an image. Does some pre-processing to that image. Displays the image. The dilemma is that I would like this process to use less memory, so that I can afford to download a higher-resolution image. However, when I download the image now, I use BitmapFactory.decodeStream(), which has the unfortunate side effect of returning an immutable Bitmap. As a result, I'm having to create a copy of the Bitmap before I can start operating on it, which means I have to have 2x the size of the Bitmap's memory allocated (at least for a brief period of time; once the copy is complete I can recycle the original). Is there a way to decode an InputStream into a mutable Bitmap?

• How to Identify a ListViewItem to Update a Single Row

  - by tunneling

  I have a ListView displays information about an object. When I click a ListView Item, I open an Activity that let's me manipulate parameters of the object held in the adapter. These parameters are updated and stored remotely. When I return to the ListView (via the back button), I want to update the ListView Item that I clicked originally by requesting the parameter values from the remote server. I am currently doing this up updating the entire ListView by clearing it and rebuilding it. How do I reference the ListView Item so that I can update the data for that item only? Thanks, Jason

• Grouping data in an NSMutable array

  - by padatronic

  Hi guys, I have an array i load with lots of data from an xml file. I am displaying this on a tableview and then when you click on say an author it goes through to display all their books.

• ForceContext Queries method twice?

  - by azz0r

  Hello, I'm doing a per minute script, to output the xml that a server will read, I am used forceContext. <?php class My_Controller_Action_Helper_ForceContext extends Zend_Controller_Action_Helper_ContextSwitch { public function initContext($format = null) { $request = $this->getRequest(); $action = $request->getActionName(); $context = $this->getActionContexts($action); //check if this is the only context if(count($context) === 1) { $format = $context[0]; } return parent::initContext($format); } } class Video_PerMinuteController extends Zend_Controller_Action { function init() { $contextSwitch = $this->_helper->getHelper('ForceContext'); $contextSwitch->addActionContext('transaction', 'xml')->initContext(); In my method, it gets the current minute count, adds 1, then saves. So I can clearly see when its accessed more than once in a minute. If I comment out the second contextSwitch line, it only goes up 1, if Its not, it displays the xml page but adds 2 minutes (being called twice somehow). Any ideas?

• How to get Resharper to show a Refactoring that it already has.

  - by AngryHacker

  Whenever Resharper encounters code like this: (treeListNode.Tag as GridLine).AdvertiserSeparation = 5; it presents you with a possible fix (since treeListNode.Tag as GridLine might be null). It says: 'Replace with Direct Cast', which turns the code into the following: ((GridLine) treeListNode.Tag).AdvertiserSeparation = 5; This is great. However, when it encounters code like this: GridLine line = treeListNode.Tag as GridLine; line.AdvertiserSeparation = 5; Resharper simply displays a warning 'Possible System.NullReferenceException', but does not offer me to 'Replace with Direct Cast'. Is there a way to make Resharper offer me this refactoring, since it already has it?

• Webwork actions, the lifecycle of variables declared in the action class.

  - by Sam

  Hi all, I'm using the webwork framework (JIRA plugin development) and was wondering about the lifecycle of the variables in the action class. I have a few private variables in the action class that are set when during the doDefault() method. These are used in the input view to set up jqGrid columns and then when the user has entered some data they click submit which puts the grid data into a hidden input. The next thing that happens is the doValidation() method is called before the doExecute(), which displays the input view if there are any errors. The problem is that the variables set up in the doDefault() method are now null. Can anyone explain to me how the lifecycle of variables works in the webwork actions? Cheers

• Instant Messenger: How does gtalk/yahoo messenger populate the contact list?

  - by Owen

  Hi All, We are currently working on a small IM project which pretty much works like gtalk and yahoo messenger. We came across a problem that puzzled us how gtalk/ym populate their contact lists. Given that the user has let's say more or less 500 contacts, both IMs seem to readily load the contacts pretty fast and already sorted. Here are my questions(referring to either): Does it cache its contacts, like saving it in a file somewhere upon exit so that upon log-in it readily extracts the contacts and displays it in its contact list? Does it always request for the VCARDS upon log in? OR they have a VCARD push or whatever that simply updates the contacts' profiles (like that of their status [presence push - available, busy, etc...] )?

• Silverlight Scrollable Content Problem

  - by Steve

  I am fairy new to Silverlight and I have a problem. I have a grid on a page that is resizable when the user resizes their browser window. In one of the grids columns I want to display dynamically added content that is scrollable, as there is more data than space available. I currently have a scrollViewer with a stack panel inside it, that i programmatically add a user control to and then several user controls to that control depending on the amount of content. My problem is this. The scrollViewer does not respect the available space and as such displays its content outside of the viewable area when there is more data than space. i.e. it does not uses it is not scrollable nature. Hopefully this is something simple that I have missed, but i am banging my head against the wall at the moment. Any help gratefully received.

• How do I include 2 tables in one LocalStorage item?

  - by Noor

  I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localStorage to only store one of the tables (I assume the first).. I've thought of different solutions and I wonder if someone could point out the pro's and con's (if the solutions even works that is). Make a loop that checks the page after tables and stores them into an array of localStorage-items.. I'd have to dynamically create a localStorage item for each table. Take the whole div that the tables are in, and store that in the localStorage, when a user revisits the page, the page checks after the items in storage and displays the whole divs. Any suggestions you have that can beat this :).. (but no cache, it has to be with the localStorage!) Thanks

• Graph Generation in flex

  - by Roshan

  I need to generate a graph using the following XML in FLEX. [Bindable] public var stockDataAC:ArrayCollection = new ArrayCollection( [ {date: "2010, 4, 27", close: 41.71}, {date: "2010, 4, 28", close: 42.21}, {date: "2010, 5, 2", close: 42.71}, {date: "2010, 5, 3", close: 42.99}, {date: "2010, 5, 4", close: 44} ]); .............. < mx:horizontalAxis < mx:DateTimeAxis dataUnits="days" displayLocalTime="true" parseFunction="myParseFunction" / < /mx:horizontalAxis But this displays the graph from 2010/4/27 till 2010/5/4 including 2010/4/29, 2010/4/30 and 2010/5/1. I require the graph to display only the points in XML and exclude remaining thought it lies in between since it contains no data. How this can be done?

• how to get the top left coordinates of the screen with javascript on firefox

  - by artsince

  I have a <div> element with position: absolute and z-index something big. I would like to cover the entire screen with this div with javascript. This is what I do and it works: document.getElementById('mydiv').style.top = 0; document.getElementById('mydiv').style.left = 0; document.getElementById('mydiv').style.width = '100%'; document.getElementById('mydiv').style.height = '100%'; However, when I scroll down with long webpages, this code displays my div at the top of the page, so the div renders above the region I currently view. How can I change the top and left values so that my div always covers the active field I am viewing? I work on firefox 3.6.*. Thank you

• Boolean issues in PHP

  - by McNabbToSkins

  I have a question regarding bools in php. I have a stored mysql proc that is returning a boolean. When this value is grabbed on the php side it displays the value as being a 0 or 1. This all seems fine to me and I have read in the php manual that php will interpret a 0 or 1 as false or true at compile time but this does not seem to be the case to me. I have gone a step further and casted my returned value with (bool) but this still does not seem to work. My if statements are not properly firing because of this. Does anyone know what is going on? Thanks for the help.

• Unsigned long with negative value

  Please see the simple code below: #include <iostream> #include <stdlib.h> using namespace std; int main(void) { unsigned long currentTrafficTypeValueDec; long input; input=63; currentTrafficTypeValueDec = (unsigned long) 1LL << input; cout << currentTrafficTypeValueDec << endl; printf("%u \n", currentTrafficTypeValueDec); printf("%ld \n", currentTrafficTypeValueDec); return 0; } Why printf() displays the currentTrafficTypeValueDec (unsigned long) with negative value?

• JavaScript setInterval loop not holding variable

  - by Ryan

  Here is my code: var showNo = 1; window.setInterval(function() { console.log(showNo); if(showNo === 1) { var nextNo = 2; } else if(showNo === 2) { var nextNo = 3; } else if(showNo === 3) { var nextNo = 4; } else if(showNo === 4) { var nextNo = 5; } else if(showNo === 5) { var nextNo = 1; } else { var showNo = 1; var nextNo = 2; } var showNo = nextNo; }, 500); My question is, why is the showNo variable not holding when the setInterval loop starts? The console displays 'undefined' in the above example. This may be a simple question, but I am trying to teach myself query and this has me stuck.. Any answers would be great. Thanks.
