  • Do vs. Run vs. Execute vs. Perform verbs

    - by coffeeaddict
    Before anyone starts to go nuts and red flag this post saying this is "Subjective" which drives me absolutely nuts because everyone has their own intent why they are posting something others feel are subjective. Subjective is subjective to each person, how about that! So with that let me tell you a couple things so that this post does not get flagged by flag happy moderators: 1) There are community guidlines on specific keywords recommended by certain organizations or people (e.g. Microsoft, Lance Hunt, etc.) 2) I want to know what others are using the most and why. Why they feel this verb reads better than others 3) Books even talk about this verb issue (Uncle Bob, etc.), so it's not subjective Now to my actual question: a) What list of verbs are you using for method names? What's your personal or team standard? b) I debate whether to use Do vs. Run vs. Execute vs. Perform and am wondering if any of these are no longer recommended or some that people just don't really use and I should just scratch them. Basically any one of those verbs mean the same thing...to invoke some process (method call). This is outside of CRUDs. For example: ExecutePayPalWorkflow(); that could be also any one of these names instead: DoPayPalWorkflow(); RunPayPalWorkflow(); PerformPayPalWorkflow(); or does it not really matter...because any of those verbs pretty much are understandable as to "what" shows your intent by the other words that follow it "PayPalWorkflow" This discussion can go for any language. I just put the two main tags C# and Java here which is good enough for me to get some solid answers or experiences.

  • Looping the layout that was set up in Interface Builder

    - by Slavenko
    I just need for someone to point me in the right direction of how I should be doing things. I wanted to make an iOS news like app that would have interface resembling Windows Phone. Large and small image tiles that represent one news item each. Now I was thinking to create some basic layout in storyboard, that would consist out of, for example, a title, and a 3 different sized tiles/images (the gray part on the attached image). Now, I would be getting the data as a JSON array that has holds different news categories so I was wondering if somehow the set up layout could be reused in a for loop since the layout will only repeat itself (the red part on the attached image) and oly the data would be different. Can this be done, should I even try doing something like this, or should I try to create an entire layout programmatically? I wouldn't mind doing it programatically, it's just that I don't have much experience in creating layouts that way, and wanted to make sure that I don't do something that I might regret later. Thank you for any help and advice.

  • How can I use CssResources in UiBinder a generated Cell?

    - by confile
    I want to generate a Cell for a CellWidget with the UiBinder (UiRenderer). What I did to generate the cell is in MyCell.java: public class MyCell implements AbstractCell<MyDto> { public interface Resources extends ClientBundle { @Source({Css.DEFAULT_CSS }) Css css(); } public interface Css extends CssResource { String DEFAULT_CSS = "test/MyStyle.css"; String test(); } interface MyUiRenderer extends UiRenderer { void render(SafeHtmlBuilder sb, String name, SafeStyles styles); } private static MyUiRenderer renderer = GWT.create(MyUiRenderer.class); Resources resources = GWT.create(Resources.class); @Override public void render(SafeHtmlBuilder safeHtmlBuilder, MyDto model) { SafeStyles style = SafeStylesUtils.fromTrustedString(resources.css().test().toString()); renderer.render(safeHtmlBuilder, model.getName(), style); } } My MyCell.ui.xml file looks like this: <!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'> <ui:with field="name" type="java.lang.String" /> <ui:with field='styles' type='com.google.gwt.safecss.shared.SafeStyles'/> <div style="{styles}"><ui:text from="{name}" /></div> </ui:UiBinder> MyStyle.css: .test { background-color: red; font-size: 20px; display: flex; ... } When I run my code I get the following error: [DEBUG] [mobile] - Rebinding test.client.app.MyCell.MyUiRenderer [DEBUG] [mobile] - Invoking generator com.google.gwt.uibinder.rebind.UiBinderGenerator [ERROR] [mobile] - java.lang.String required, but {styles} returns com.google.gwt.safecss.shared.SafeStyles: <div style='{styles}'> (:9) [ERROR] [mobile] - Deferred binding failed for 'test.client.app.MyCell.MyUiRenderer'; expect subsequent failures [ERROR] [mobile] - (GWT.java:72) 2014-06-08 17:15:05,214 [FATAL] Uncaught Exception: Then I tried to this: in my UiBinder but it does not work.

  • Why is my long polling code for a notification system not updating in real time? PHP MYSQL

    - by tjones
    I am making a notification system similar to the red notification on facebook. It should update the number of messages sent to a user in real time. When the message MYSQL table is updated, it should instantly notify the user, but it does not. There does not seem to be an error inserting into MYSQL because on page refresh the notifications update just fine. I am essentially using code from this video tutorial: http://www.screenr.com/SNH (which updates in realtime if a data.txt file is changed, but it is not written for MYSQL like I am trying to do) Is there something wrong with the below code: **Javascript** <script type="text/javascript"> $(document).ready(function(){ var timestamp = null; function waitForMsg(){ $.ajax({ type: "GET", url: "getData.php", data: "userid=" + userid, async: true, cache: false, success: function(data){ var json = eval('(' + data + ')'); if (json['msg'] != "") { $('.notification').fadeIn().html(json['msg']); } setTimeout('waitForMsg()',30000); }, error: function(XMLHttpRequest, textStatus, errorThrown){ setTimeout('waitForMsg()',30000); } }); } waitForMsg(); </script> <body> <div class="notification"></div> **PHP*** <?php if ($_SERVER['REQUEST_METHOD'] == 'GET' ) { $userid = $_GET['userid']; include("config.php"); $sql="SELECT MAX(time) FROM notification WHERE userid='$userid'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); $currentmodif = $row['MAX(time)']; $s="SELECT MAX(lasttimeread) FROM notificationsRead WHERE submittedby='$userid'"; $r = mysql_query($s); $rows = mysql_fetch_assoc($r); $lasttimeread = $rows['MAX(lasttimeread)']; while ($currentmodif <= $lasttimeread) { usleep(10000); clearstatcache(); $currentmodif = $row['MAX(time)']; } $response = array(); $response['msg'] = You have new messages; echo json_encode($response); } ?>

  • some problem with iOS 4.2.1

    - by bicbac
    Hi, I've been developing an app with MacBook Pro (MBP) so far. Last week one of my friends gave me new macbook air 11"(MBA). so Now I can test my code with more than one machine with the same version of developing tools - Both machine has Xcode (3.2.5) and iOS SDK 4.2.1). After some point my app starts get terminated suddenly(iPhone sumulator), and I was using MBP. I got no error message whatsoever. it just stops. I reckon the crash comes from dealing with memory, like 'release'/ 'double-release'. (I'm not 100% sure though). Anyway I thought there must be some mistake within my code for sure. -Confusion starts from this part.- With my MBA, on the other hand, I don'y see any crash. It just works fine. There is nothing different between MBA & MBP except the h/w specifications. Same code, same versions of XCode and iOS SDK. Is the fact that no crash at MBA suggesting that I have to look somewhere else than the code itself? I red some article and Q&As on iOS4.2.1 and XCode 3.2.5 that the most recent version of XCode doesn't recognize the iOS 4.2.1 since the 4.2.1 came out later the 3.2.5. Is it the reason? I have no idea at this moment what should be the next move. thanks

  • Fixing Chrome resizing behaviour

    - by bobo
    <div style="background-color:red;width: 300px;"> <div style="float:left;border:1px solid yellow;">AAA AAA AAA</div> <div style="float:left;border:1px solid green;">BBB BBB BBB</div> <div style="clear:both;"></div> </div> Pasting the above HTML here: http://htmledit.squarefree.com/ And then zoom out in Chrome, you will see that <div> B will eventually be forced down to the next row. If you do the same thing in Firefox and IE, both <div> A and B will stay on the same row. Adding a height attribute on the parent <div> may help, but if the height of the content is not known beforehand, this will not be feasible. I would like to know how this problem can be fixed in Chrome. Many thanks to you all. EDIT: uploaded a screenshot here: http://img52.imageshack.us/i/screenshot1xd.jpg/

  • How to get drag working properly in silverlight when mouse is not pressed ?

    - by Mrt
    Hello, I have the following code xaml <Canvas x:Name="LayoutRoot" > <Rectangle Canvas.Left="40" Canvas.Top="40" Width="20" Height="20" Name="rec" Fill="Red" MouseLeftButtonDown="rec_MouseLeftButtonDown" MouseMove="rec_MouseMove" /> </Canvas> code behind public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); } public Point LastDragPosition { get; set; } private bool isDragging; private void rec_MouseMove(object sender, MouseEventArgs e) { if(!isDragging) { return; } var position = e.GetPosition(rec as UIElement); var newPosition = new Point( Canvas.GetLeft(rec) + position.X - LastDragPosition.X, Canvas.GetTop(rec) + position.Y - LastDragPosition.Y); Canvas.SetLeft(rec, newPosition.X); Canvas.SetTop(rec, newPosition.Y); LastDragPosition = e.GetPosition(rec as UIElement); } private void rec_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { isDragging = true; LastDragPosition = e.GetPosition(sender as UIElement); rec.CaptureMouse(); } } This issue is the rectangle follows the mouse if the mouse left button is down, but I would like the rectangle to move even when the mouse left button isn't down. It works, but if you move the mouse very slowly. If you move the mouse to quickly the rectangle stops moving (is the mouse capture lost ?) Cheers,

  • How can I make VS2010 insert using statements in the order dictated by StyleCop rules.

    - by Hamish Grubijan
    The related default StyleCop rules are: Place using statements inside namespace. Sort using statements alphabetically. But ... System using come first (still trying to figure out if that means just using System; or using System[.*];). So, my use case: I find a bug and decide that I need to at least add an intelligible Assert to make debugging less painful for the next guy. So I start typing Debug.Assert( and intellisense marks it in Red. I hover mouse over Debug and between using System.Diagnostics; and System.Diagnostics.Debug I choose the former. This inserts using System.Diagnostics; after all other using statements. It would be nice if VS2010 did not assist me in writing code that won't build due to warnings as errors. How can I make VS2010 smarter? Is there some sort of setting, or does this require a full-fledged add-in of some sort?

  • Javascript style variables with "-" in their name aren't able to be changed?

    - by William
    Okay, so this bug has cost me quite a bit of time and embarrassment. It seems that any style variable with a - in it's name can't be modified by javascript. As seen here: <!DOCTYPE html> <html lang="en"> <head> <title>Class Test</title> <meta charset="utf-8" /> <style> body { text-align: center; background-color: #ffffff;} #box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;} </style> <script type="text/javascript"> var box = 0; </script> </head> <body> <div id="box" ></div> <script type="text/javascript"> box = document.getElementById('box'); box.style.background-color = "#0000ff"; </script> </body> </html> The box in said example will just remain red. So how do I change a style variable with a - in it's name?

  • How to convert X/Y position to Canvas Left/Top properties when using ItemsControl

    - by kshahar
    I am trying to use a Canvas to display objects that have "world" location (rather than "screen" location). The canvas is defined like this: <Canvas Background="AliceBlue"> <ItemsControl Name="myItemsControl" ItemsSource="{Binding MyItems}"> <ItemsControl.ItemTemplate> <DataTemplate> <Canvas> <TextBlock Canvas.Left="{Binding WorldX}" Canvas.Top="{Binding WorldY}" Text="{Binding Text}" Width="Auto" Height="Auto" Foreground="Red" /> </Canvas> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Canvas> MyItem is defined like this: public class MyItem { public MyItem(double worldX, double worldY, string text) { WorldX = worldX; WorldY = worldY; Text = text; } public double WorldX { get; set; } public double WorldY { get; set; } public string Text { get; set; } } In addition, I have a method to convert between world and screen coordinates: Point worldToScreen(double worldX, double worldY) { // return screen coordinates using the canvas properties and an internal MapData object } With the current implementation, the items are positioned in the wrong location, because their location is not converted to screen coordinates. How can I apply the worldToScreen method on the MyItem objects before they are added to the canvas?

  • Can we solve the table row background image problem, in chrome, in multi celled tables??

    - by Ya'el
    It is frequently asked – but I haven’t seen a good answer yet (and I looked). If you set a background image in CSS to a table row- the image will repeat itself in every cell. If you set the position: relative (for the row) and set the background-image: none (for the cells) it solves the problem on IE but not on chrome! I can't use background positioning since there are many calls and their size varies. (And the picture is not symmetrical- It's a fade out from one side. Anybody?? Example for the css code : tr { height: 30px; position:relative;} tr.green {background: url('green_30.png') no-repeat left top;} tr.orange {background: url('oranger_30.png') no-repeat left top;} tr.red {background: url('red_30.png') no-repeat left top;} td {background-image:none;} The HTML is basic - A multi cell table. The goal is to have different colors fade into every row, but it could be any non-pattern image.

  • Align child element to bottom with CSS

    - by alex
    I have a form input, and the label spans multiple lines, and I want the corresponding checkbox to appear at the bottom (last line of the label element). Here is what I was playing with CSS .standard-form { width: 500px; border: 1px solid red; } .standard-form .input-row { overflow: hidden; margin-bottom: 0.8em; } .standard-form label { width: 25%; float: left; } .standard-form .input-container { width: 70%; float: right; } .standard-form .checkbox .input-container { display: table-cell; height: 100%; vertical-align: text-bottom; } HTML <form class="standard-form"> <div class="input-row checkbox" id="permission"> <label for="input-permission"> Do I hereby grant you permission to do whatever tasks are neccessary to achieve an ideal outcome? </label> <div class="input-container"> <input type="checkbox" id="input-permission" name="permission" value="true" /> </div> </div> </form> It is also online at JSbin. Is there any way to do this? I notice that div.input-container isn't expanding, which is the old multi column problem with CSS. I thought I could get this going with display: table-cell and vertical-align: bottom but I haven't been able to do it yet. I don't mind that IE6/7 won't render it correctly.

  • Declaring an enum within a class

    - by bporter
    In the following code snippet, the Color enum is declared within the Car class in order to limit the scope of the enum and to try not to "pollute" the global namespace. class Car { public: enum Color { RED, BLUE, WHITE }; void SetColor( Car::Color color ) { _color = color; } Car::Color GetColor() const { return _color; } private: Car::Color _color; }; (1) Is this a good way to limit the scope of the Color enum? Or, should I declare it outside of the Car class, but possibly within its own namespace or struct? I just came across this article today, which advocates the latter and discusses some nice points about enums: http://gamesfromwithin.com/stupid-c-tricks-2-better-enums. (2) In this example, when working within the class, is it best to code the enum as Car::Color, or would just Color suffice? (I assume the former is better, just in case there is another Color enum declared in the global namespace. That way, at least, we are explicit about the enum to we are referring.) Thanks in advance for any input on this.

  • Recommendations for IPC between parent and child processes in .NET?

    - by Jeremy
    My .NET program needs to run an algorithm that makes heavy use of 3rd party libraries (32-bit), most of which are unmanaged code. I want to drive the CPU as hard as I can, so the code runs several threads in parallel to divide up the work. I find that running all these threads simultaneously results in temporary memory spikes, causing the process' virtual memory size to approach the 2 GB limit. This memory is released back pretty quickly, but occasionally if enough threads enter the wrong sections of code at once, the process crosses the "red line" and either the unmanaged code or the .NET code encounters an out of memory error. I can throttle back the number of threads but then my CPU usage is not as high as I would like. I am thinking of creating worker processes rather than worker threads to help avoid the out of memory errors, since doing so would give each thread of execution its own 2 GB of virtual address space (my box has lots of RAM). I am wondering what are the best/easiest methods to communicate the input and output between the processes in .NET? The file system is an obvious choice. I am used to shared memory, named pipes, and such from my UNIX background. Is there a Windows or .NET specific mechanism I should use?

  • Google maps and J-Query: Individual markers?

    - by user351189
    Hi there, I have created a Google maps mashup, where with a bit of input, I have managed to have a sidebar that links to a video icon/marker that then opens up an info window showing virtual tours. I would, however, like to put different coloured marker icons on the map depending on the category that the video is in. This would be easy enough to do, but my page is made up of a mixture of J-Query and JavaScript all calling to the individual flash files. Could someone help me with the code for adding extra marker icons for different categories? Here is the code: So, after the intial 'var camera;' point, there comes this: function addMarker(point, title, video, details) { var marker = new GMarker(point, {title: title, icon:camera}); GEvent.addListener(marker, "click", function() { if (details) { marker.openInfoWindowTabsHtml([new GInfoWindowTab("Video", video), new GInfoWindowTab("More", details)]); } else { marker.openInfoWindowHtml(video); } }); Then further down, is the code for calling the individual marker image. I would like to add another image to this list - would I start out by calling the new object 'camera-red.image' or something similar? function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("mapDiv")); map.setCenter(new GLatLng(51.52484592590448, -0.13345599174499512), 17); map.setUIToDefault(); var uclvtSatMapType = createUclVTSatMapType() map.addMapType(uclvtSatMapType); map.setMapType(uclvtSatMapType); camera = new GIcon(G_DEFAULT_ICON); camera.image = "ucl-video.png"; camera.iconSize = new GSize(32,37); camera.iconAnchor = new GPoint(16,35); camera.infoWindowAnchor = new GPoint(16,2); addMarkersToMap(); } The actual map can be found here: link text Thanks.

  • ActionScript 3.0 Color Output Error?

    - by TheDarkIn1978
    I'm employing color in a current AS3 project, and have come across what appears to be an error in the Flash Player (version 10). it might also be an error with Apple's DigitalColor Meter (version 3.7.2), which is what i'm using to sample the displayed colors on Mac OS X Snow Leopard (version 10.6.3). //Primary, secondary, and tertiary colors of the RGB color wheel var red:Number = 0xFF0000; var orange:Number = 0xFF7D00; var yellow:Number = 0xFFFF00; var chartreuse:Number = 0x7DFF00; var green:Number = 0x00FF00; var spring:Number = 0x00FF7D; var cyan:Number = 0x00FFFF; var azure:Number = 0x007DFF; //reads 0x0077FF var blue:Number = 0x0000FF; var violet:Number = 0x7D00FF; var magenta:Number = 0xFF00FF; //reads 0xFF00F8 var rose:Number = 0xFF007D; //reads 0xFF0077 all of these colors display normally except for 3: Azure, Magenta and Rose. they are coded with the appropriate number, but when i use the color meter to sample the displayed colors, those 3 return inaccurate results. anyone have any insight about this issue? what is causing the error, the Flash runtime or the color sampler? if it's the Flash player, could this problem be much deeper? *sampling this image will return inaccurate results due to .jpg compression. it's simply for illustration

  • tracking the position of dragview

    - by user262325
    Hello everyone I put a dragview on an UIView, I hope when I drag the dragview, its superview (UIView) tracks the position of the dragview and moves itself to the position where to keep dragview at the original position on the UIView. The codes show below: #import <UIKit/UIKit.h> @interface DragView : UIImageView { CGPoint startLocation; } @end #import "DragView.h" @implementation DragView - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { // Drawing code } -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent*)event { CGPoint pt=[[touches anyObject] locationInView:self]; startLocation=pt; [[self superview] bringSubviewToFront:self]; } -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint pt=[[touches anyObject] locationInView:self]; CGRect frame=[self frame]; frame.origin.x+=pt.x-startLocation.x; frame.origin.y+=pt.y-startLocation.y; CGRect frame1=[[self superview] frame];//superview of the dragview frame1.origin.x+=frame.origin.x; //tracks the postion of dragview frame1.origin.y+=frame.origin.y; [[self superview] setFrame: frame1 ]; //move to new position [self setFrame:frame]; } my problem is that the UIView moved but lagged to the movement of the drageview(RED BLOCK). Welcome any comment Thanks interdev
