• Property trigger in XAML for IsMouseOver fails to set Border.Background

  - by Mal Ross

  I'm currently trying to create a ControlTemplate for the Button class in WPF, replacing the usual visual tree with something that makes the button look similar to the little (X) close icon on Google Chrome's tabs. I decided to use a Path object in XAML to achieve the effect. Using a property trigger, the control responds to a change in the IsMouseOver property by setting the icon's red background. Here's the XAML from a test app: <Window x:Class="Widgets.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Window.Resources> <Style x:Key="borderStyle" TargetType="Border"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background"> <Setter.Value> <SolidColorBrush Color="#CC0000"/> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> <ControlTemplate x:Key="closeButtonTemplate" TargetType="Button"> <Border Width="12" Height="12" CornerRadius="6" BorderBrush="#AAAAAA" Background="Transparent" Style="{StaticResource borderStyle}" ToolTip="Close"> <Viewbox Margin="2.75"> <Path Data="M 0,0 L 10,10 M 0,10 L 10,0" Stroke="{Binding BorderBrush, RelativeSource={RelativeSource FindAncestor, AncestorType=Border, AncestorLevel=1}}" StrokeThickness="1.8"/> </Viewbox> </Border> </ControlTemplate> </Window.Resources> <Grid Background="White"> <Button Template="{StaticResource closeButtonTemplate}"/> </Grid> </Window> Note that the circular background is always there - it's just transparent when the mouse isn't over it. The problem with this is that the trigger just isn't working. Nothing changes in the button's appearance. However, if I remove the Background="Transparent" value from the Border object in the ControlTemplate, the trigger does work (albeit only when over the 'X'). I really can't explain this. Setters for any other properties placed in the borderStyle resource work fine, but the Background setter fails as soon as the default background is specified in the ControlTemplate. Any ideas why it's happening and how I can fix it? I know I could easily replace this code with, for example, a .PNG-based image, but I want to understand why the current implementation isn't working. Thanks! :)

• How to get ImageButton size within Android GridView?

  - by wufoo

  I'm subclassing ImageButton in order to draw lines on it and trying to figure out where the actual button coordinates are within my gridview. I am using onGlobalLayout to setup Top, Bottom, Right and Left, but these seem to be for the actual "square" within the grid, and not the actual button (see image). The purple lines are drawn in myImageButton.onDraw() using coords gathered from myImageButton.onGlobalLayout(). I thought these would be for the button, but they seem to be from something else. Not sure what. I'd like the purple lines to match the outline of the button so the lines I draw appear on the button and not just floating out in the LinearLayout somewhere. The light blue is the background color of the vertical LinearLayout holding the Textview (for the number) and myImageButton. Any way to get the actual button size? XML Layout: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/lay_cellframe" android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="fill_vertical|fill_horizontal" android:orientation="vertical" > <TextView android:id="@+id/tv_cell" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="2dp" android:gravity="center" android:text="TextView" android:textSize="10sp" /> <com.example.icaltest2.myImageButton android:id="@+id/imageButton1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_margin="0dp" android:adjustViewBounds="false" android:background="@android:drawable/btn_default" android:scaleType="fitXY" android:src="@android:color/transparent" /> </LinearLayout> </FrameLayout> myImageButton.java public myImageButton (Context context, AttributeSet attrs) { super (context, attrs); mBounds = new Rect(); ViewTreeObserver vto = this.getViewTreeObserver (); vto.addOnGlobalLayoutListener (ogl); Log.d (TAG, "myImageButton"); } ... OnGlobalLayoutListener ogl = new OnGlobalLayoutListener() { @Override public void onGlobalLayout () { Rect b = getDrawable ().getBounds (); mBtnTop = b.centerY () - (b.height () / 2); mBtnBot = b.centerY () + (b.height () / 2); mBtnLeft = b.centerX () - (b.width () / 2); mBtnRight = b.centerX () + (b.width () / 2); } }; ... @Override protected void onDraw (Canvas canvas) { super.onDraw (canvas); Paint p = new Paint (); p.setStyle (Paint.Style.STROKE); p.setStrokeWidth (1); p.setColor (Color.MAGENTA); canvas.drawCircle (mBtnLeft, mBtnTop, 2, p); canvas.drawCircle (mBtnLeft, mBtnBot, 2, p); canvas.drawCircle (mBtnRight, mBtnTop, 2, p); canvas.drawCircle (mBtnRight, mBtnBot, 2, p); canvas.drawRect (mBtnLeft, mBtnTop, mBtnRight, mBtnBot, p); }

• Animating and moving a draggable shape in KineticJS's dragend event

  - by user3712941

  I would like to animate moving a draggable shape to another position after it has been dragged in KineticJS. I would like to animate the movement of the shape over a period of time (for example, over 1 second). For example, I create a draggable shape and save its initial xy coordinates. I register a "dragend" event on this shape. Then, I drag the shape to a new position. When I release the drag, the dragend event is called. In that event function, I want to animate/ease the shape back to its original position. See my JSFiddle for a complete example: DragSample. (function () { //create variables at global scope var layer; var stage; var triangle; var triangleLastX = 190; var triangleLastY = 120; var tween; function initTween() { tween = new Kinetic.Tween({ node: triangle, duration: 1, easing: Kinetic.Easings.EaseInOut, x: 400, y: 200, }); } this.init = function () { layer = new Kinetic.Layer(); stage = new Kinetic.Stage({ container: 'container', width: 800, height: 600 }); triangle = new Kinetic.RegularPolygon({ x: 190, y: 120, sides: 3, radius: 80, fill: '#00D2FF', stroke: 'black', strokeWidth: 4, draggable: true }); triangle.on('dragstart', function () { triangleLastX = triangle.attrs.x; triangleLastY = triangle.attrs.y; }); triangle.on('dragend', function () { tween.play(); stage.draw(); }); layer.add(triangle); stage.add(layer); initTween (); } window.onload = init(); })(); I have tried doing this several ways. The last way I attempted to do this was using Kinetic's Tween(), however, when I play this Tween from the dragend event handler function, it moves the shape back to its original position immediately (i.e. the position when the drag started), then applies the Tween. Is there any way to achieve animating the movement of a draggable shape to its original position (or any other position for that matter) in dragend using KineticJS?

• Generate Strongly Typed Observable Events for the Reactive Extensions for .NET (Rx)

  - by Bobby Diaz

  I must have tried reading through the various explanations and introductions to the new Reactive Extensions for .NET before the concepts finally started sinking in.  The article that gave me the ah-ha moment was over on SilverlightShow.net and titled Using Reactive Extensions in Silverlight.  The author did a good job comparing the "normal" way of handling events vs. the new "reactive" methods. Admittedly, I still have more to learn about the Rx Framework, but I wanted to put together a sample project so I could start playing with the new Observable and IObservable<T> constructs.  I decided to throw together a whiteboard application in Silverlight based on the Drawing with Rx example on the aforementioned article.  At the very least, I figured I would learn a thing or two about a new technology, but my real goal is to create a fun application that I can share with the kids since they love drawing and coloring so much! Here is the code sample that I borrowed from the article: var mouseMoveEvent = Observable.FromEvent<MouseEventArgs>(this, "MouseMove"); var mouseLeftButtonDown = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonDown"); var mouseLeftButtonUp = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonUp");       var draggingEvents = from pos in mouseMoveEvent                              .SkipUntil(mouseLeftButtonDown)                              .TakeUntil(mouseLeftButtonUp)                              .Let(mm => mm.Zip(mm.Skip(1), (prev, cur) =>                                  new                                  {                                      X2 = cur.EventArgs.GetPosition(this).X,                                      X1 = prev.EventArgs.GetPosition(this).X,                                      Y2 = cur.EventArgs.GetPosition(this).Y,                                      Y1 = prev.EventArgs.GetPosition(this).Y                                  })).Repeat()                          select pos;       draggingEvents.Subscribe(p =>     {         Line line = new Line();         line.Stroke = new SolidColorBrush(Colors.Black);         line.StrokeEndLineCap = PenLineCap.Round;         line.StrokeLineJoin = PenLineJoin.Round;         line.StrokeThickness = 5;         line.X1 = p.X1;         line.Y1 = p.Y1;         line.X2 = p.X2;         line.Y2 = p.Y2;         this.LayoutRoot.Children.Add(line);     }); One thing that was nagging at the back of my mind was having to deal with the event names as strings, as well as the verbose syntax for the Observable.FromEvent<TEventArgs>() method.  I came up with a couple of static/helper classes to resolve both issues and also created a T4 template to auto-generate these helpers for any .NET type.  Take the following code from the above example: var mouseMoveEvent = Observable.FromEvent<MouseEventArgs>(this, "MouseMove"); var mouseLeftButtonDown = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonDown"); var mouseLeftButtonUp = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonUp"); Turns into this with the new static Events class: var mouseMoveEvent = Events.Mouse.Move.On(this); var mouseLeftButtonDown = Events.Mouse.LeftButtonDown.On(this); var mouseLeftButtonUp = Events.Mouse.LeftButtonUp.On(this); Or better yet, just remove the variable declarations altogether:     var draggingEvents = from pos in Events.Mouse.Move.On(this)                              .SkipUntil(Events.Mouse.LeftButtonDown.On(this))                              .TakeUntil(Events.Mouse.LeftButtonUp.On(this))                              .Let(mm => mm.Zip(mm.Skip(1), (prev, cur) =>                                  new                                  {                                      X2 = cur.EventArgs.GetPosition(this).X,                                      X1 = prev.EventArgs.GetPosition(this).X,                                      Y2 = cur.EventArgs.GetPosition(this).Y,                                      Y1 = prev.EventArgs.GetPosition(this).Y                                  })).Repeat()                          select pos; The Move, LeftButtonDown and LeftButtonUp members of the Events.Mouse class are readonly instances of the ObservableEvent<TTarget, TEventArgs> class that provide type-safe access to the events via the On() method.  Here is the code for the class: using System; using System.Collections.Generic; using System.Linq;   namespace System.Linq {     /// <summary>     /// Represents an event that can be managed via the <see cref="Observable"/> API.     /// </summary>     /// <typeparam name="TTarget">The type of the target.</typeparam>     /// <typeparam name="TEventArgs">The type of the event args.</typeparam>     public class ObservableEvent<TTarget, TEventArgs> where TEventArgs : EventArgs     {         /// <summary>         /// Initializes a new instance of the <see cref="ObservableEvent"/> class.         /// </summary>         /// <param name="eventName">Name of the event.</param>         protected ObservableEvent(String eventName)         {             EventName = eventName;         }           /// <summary>         /// Registers the specified event name.         /// </summary>         /// <param name="eventName">Name of the event.</param>         /// <returns></returns>         public static ObservableEvent<TTarget, TEventArgs> Register(String eventName)         {             return new ObservableEvent<TTarget, TEventArgs>(eventName);         }           /// <summary>         /// Creates an enumerable sequence of event values for the specified target.         /// </summary>         /// <param name="target">The target.</param>         /// <returns></returns>         public IObservable<IEvent<TEventArgs>> On(TTarget target)         {             return Observable.FromEvent<TEventArgs>(target, EventName);         }           /// <summary>         /// Gets or sets the name of the event.         /// </summary>         /// <value>The name of the event.</value>         public string EventName { get; private set; }     } } And this is how it's used:     /// <summary>     /// Categorizes <see cref="ObservableEvents"/> by class and/or functionality.     /// </summary>     public static partial class Events     {         /// <summary>         /// Implements a set of predefined <see cref="ObservableEvent"/>s         /// for the <see cref="System.Windows.System.Windows.UIElement"/> class         /// that represent mouse related events.         /// </summary>         public static partial class Mouse         {             /// <summary>Represents the MouseMove event.</summary>             public static readonly ObservableEvent<UIElement, MouseEventArgs> Move =                 ObservableEvent<UIElement, MouseEventArgs>.Register("MouseMove");               // additional members omitted...         }     } The source code contains a static Events class with prefedined members for various categories (Key, Mouse, etc.).  There is also an Events.tt template that you can customize to generate additional event categories for any .NET type.  All you should have to do is add the name of your class to the types collection near the top of the template:     types = new Dictionary<String, Type>()     {         //{ "Microsoft.Maps.MapControl.Map, Microsoft.Maps.MapControl", null }         { "System.Windows.FrameworkElement, System.Windows", null },         { "Whiteboard.MainPage, Whiteboard", null }     }; The template is also a bit rough at this point, but at least it generates code that *should* compile.  Please let me know if you run into any issues with it.  Some people have reported errors when trying to use T4 templates within a Silverlight project, but I was able to get it to work with a little black magic...  You can download the source code for this project or play around with the live demo.  Just be warned that it is at a very early stage so don't expect to find much today.  I plan on adding alot more options like pen colors and sizes, saving, printing, etc. as time permits.  HINT: hold down the ESC key to erase!

• Loop through values and display in a pdf file

  - by chupinette

  Hello all! i have written the following code: As you can see there is a for loop to go through some values and display them in the generated pdf. The problem is that all the values are being written at the same place. I have tried to insert a new line but it does not seem to work. Can anyone suggest me how i can do it?

• What git branching models actually work - the final question

  - by UncleCJ

  In our company we have successfully deployed git and we are currently using a simple trunk/release/hotfixes branching model. However, this has it's problems, I have some key issues of confusion in the community which would be awesome to have answered here. Maybe my hopes for an Alexander stroke are too great, quite possibly I'll decompose this question into more manageable issues, but here's my first shot. Workflows / branching models - below are the three main descriptions of this I have seen, but they are partially contradicting each other or don't go far enough to sort out the subsequent issues we've run into (as described below). Thus our team so far defaults to not so great solutions. Are you doing something better? gitworkflows(7) Manual Page (nvie) A successful Git branching model (reinh) A Git Workflow for Agile Teams Merging vs rebasing (tangled vs sequential history) - the bids on this are as confusing as it gets. Should one pull --rebase or wait with merging back to the mainline until your task is finished? Personally I lean towards merging since this preserves a visual illustration of on which base a task was started and finished, and I even prefer merge --no-ff for this purpose. It has other drawbacks however. Also many haven't realized the useful property of merging - that it isn't commutative (merging a topic branch into master does not mean merging master into the topic branch). I am looking for a natural workflow - sometimes mistakes happen because our procedures don't capture a specific situation with simple rules. For example a fix needed for earlier releases should of course be based sufficiently downstream to be possible to merge upstream into all branches necessary (is the usage of these terms clear enough?). However it happens that a fix makes it into the master before the developer realizes it should have been placed further downstream, and if that is already pushed (even worse, merged or something based on it) then the option remaining is cherry-picking, with it's associated perils... What simple rules like such do you use? Also in this is included the awkwardness of one topic branch necessarily excluding other topic branches (assuming they are branched from a common baseline). Developers don't want to finish a feature to start another one feeling like the code they just wrote is not there anymore How to avoid creating merge conflicts (due to cherry-pick)? What seems like a sure way to create a merge conflict is to cherry-pick between branches, they can never be merged again? Would applying the same commit in revert (how to do this?) in either branch possibly solve this situation? This is one reason I do not dare to push for a largely merge-based workflow. How to decompose into topical branches? - We realize that it would be awesome to assemble a finished integration from topic branches, but often work by our developers is not clearly defined (sometimes as simple as "poking around") and if some code has already gone into a "misc" topic, it can not be taken out of there again, according to the question above? How do you work with defining/approving/graduating/releasing your topic branches? Proper procedures like code review and graduating would of course be lovely, but we simply cannot keep things untangled enough to manage this - any suggestions? integration branches, illustration please? Vote and comment as much as you'd like, I'll try to keep the issue page clear and informative enough. Thanks! Below is a list of related topics on stackoverflow I have checked out: What are some good strategies to allow deployed applications to be hotfixable? Workflow description for git usage for in-house development Git workflow for corporate Linux kernel development How do you maintain development code and production code?

• How to parametrize WPF Style?

  - by Konstantin

  Hi! I'm looking for a simplest way to remove duplication in my WPF code. Code below is a simple traffic light with 3 lights - Red, Amber, Green. It is bound to a ViewModel that has one enum property State taking one of those 3 values. Code declaring 3 ellipses is very duplicative. Now I want to add animation so that each light fades in and out - styles will become even bigger and duplication will worsen. Is it possible to parametrize style with State and Color arguments so that I can have a single style in resources describing behavior of a light and then use it 3 times - for 'Red', 'Amber' and 'Green' lights? <UserControl.Resources> <l:TrafficLightViewModel x:Key="ViewModel" /> </UserControl.Resources> <StackPanel Orientation="Vertical" DataContext="{StaticResource ViewModel}"> <StackPanel.Resources> <Style x:Key="singleLightStyle" TargetType="{x:Type Ellipse}"> <Setter Property="StrokeThickness" Value="2" /> <Setter Property="Stroke" Value="Black" /> <Setter Property="Height" Value="{Binding Width, RelativeSource={RelativeSource Self}}" /> <Setter Property="Width" Value="60" /> <Setter Property="Fill" Value="LightGray" /> </Style> </StackPanel.Resources> <Ellipse> <Ellipse.Style> <Style TargetType="{x:Type Ellipse}" BasedOn="{StaticResource singleLightStyle}"> <Style.Triggers> <DataTrigger Binding="{Binding State}" Value="Red"> <Setter Property="Fill" Value="Red" /> </DataTrigger> </Style.Triggers> </Style> </Ellipse.Style> </Ellipse> <Ellipse> <Ellipse.Style> <Style TargetType="{x:Type Ellipse}" BasedOn="{StaticResource singleLightStyle}"> <Style.Triggers> <DataTrigger Binding="{Binding State}" Value="Amber"> <Setter Property="Fill" Value="Red" /> </DataTrigger> </Style.Triggers> </Style> </Ellipse.Style> </Ellipse> <Ellipse> <Ellipse.Style> <Style TargetType="{x:Type Ellipse}" BasedOn="{StaticResource singleLightStyle}"> <Style.Triggers> <DataTrigger Binding="{Binding State}" Value="Green"> <Setter Property="Fill" Value="Green" /> </DataTrigger> </Style.Triggers> </Style> </Ellipse.Style> </Ellipse> </StackPanel>

• Flex chart not displaying right values along x axis.

  - by Shah Al

  I don't know of any better way to ask this question. If the below code is run (i know the cData sections are not visible in the preview, something causes it to be ignored). The result does not represent the data correctly. 1. Flex ignores missing date 24 aug for DECKER. 2. It wrongly associates 42.77 to 23-Aug instead of 24-AUG. Is there a way in flex, where the x-axis is a union of all available points ? The below code is entirely from : Adobe website link I have only commented 2 data points. //{date:"23-Aug-05", close:45.74}, and //{date:"24-Aug-05", close:150.71}, <?xml version="1.0"?> [Bindable] public var SMITH:ArrayCollection = new ArrayCollection([ {date:"22-Aug-05", close:41.87}, //{date:"23-Aug-05", close:45.74}, {date:"24-Aug-05", close:42.77}, {date:"25-Aug-05", close:48.06}, ]); [Bindable] public var DECKER:ArrayCollection = new ArrayCollection([ {date:"22-Aug-05", close:157.59}, {date:"23-Aug-05", close:160.3}, //{date:"24-Aug-05", close:150.71}, {date:"25-Aug-05", close:156.88}, ]); [Bindable] public var deckerColor:Number = 0x224488; [Bindable] public var smithColor:Number = 0x884422; ]] <mx:horizontalAxisRenderers> <mx:AxisRenderer placement="bottom" axis="{h1}"/> </mx:horizontalAxisRenderers> <mx:verticalAxisRenderers> <mx:AxisRenderer placement="left" axis="{v1}"> <mx:axisStroke>{h1Stroke}</mx:axisStroke> </mx:AxisRenderer> <mx:AxisRenderer placement="left" axis="{v2}"> <mx:axisStroke>{h2Stroke}</mx:axisStroke> </mx:AxisRenderer> </mx:verticalAxisRenderers> <mx:series> <mx:ColumnSeries id="cs1" horizontalAxis="{h1}" dataProvider="{SMITH}" yField="close" displayName="SMITH" > <mx:fill> <mx:SolidColor color="{smithColor}"/> </mx:fill> <mx:verticalAxis> <mx:LinearAxis id="v1" minimum="40" maximum="50"/> </mx:verticalAxis> </mx:ColumnSeries> <mx:LineSeries id="cs2" horizontalAxis="{h1}" dataProvider="{DECKER}" yField="close" displayName="DECKER" > <mx:verticalAxis> <mx:LinearAxis id="v2" minimum="150" maximum="170"/> </mx:verticalAxis> <mx:lineStroke> <mx:Stroke color="{deckerColor}" weight="4" alpha="1" /> </mx:lineStroke> </mx:LineSeries> </mx:series> </mx:ColumnChart> <mx:Legend dataProvider="{myChart}"/>

• Custom ProgressBarBrushConverter Not Filling In ProgressBar

  - by Wonko the Sane

  Hello All, I am attempting to create a custom ProgressBarBrushConverter, based on information from here and here. However, when it runs, the progress is not being shown. If I use the code found in the links, it appears to work correctly. Here is the converter in question: public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) { ProgressBar progressBar = null; foreach (object value in values) { if (value is ProgressBar) { progressBar = value as ProgressBar; break; } } if (progressBar == null) return DependencyProperty.UnsetValue; FrameworkElement indicator = progressBar.Template.FindName("PART_Indicator", progressBar) as FrameworkElement; DrawingBrush drawingBrush = new DrawingBrush(); drawingBrush.Viewport = drawingBrush.Viewbox = new Rect(0.0, 0.0, indicator.ActualWidth, indicator.ActualHeight); drawingBrush.ViewportUnits = BrushMappingMode.Absolute; drawingBrush.TileMode = TileMode.None; drawingBrush.Stretch = Stretch.None; DrawingGroup group = new DrawingGroup(); DrawingContext context = group.Open(); context.DrawRectangle(progressBar.Foreground, null, new Rect(0.0, 0.0, indicator.ActualWidth, indicator.ActualHeight)); context.Close(); drawingBrush.Drawing = group; return drawingBrush; } Here is the ControlTemplate (the MultiBinding is to make sure that the converter is called whenever the Value or IsIndeterminate properties are changed): <ControlTemplate x:Key="customProgressBarTemplate" TargetType="{x:Type ProgressBar}"> <Grid> <Path x:Name="PART_Track" HorizontalAlignment="Left" VerticalAlignment="Top" Stretch="Fill" StrokeLineJoin="Round" Stroke="#DDCBCBCB" StrokeThickness="4" Data="M 20,100 L 80,10 C 100,120 160,140 190,180 S 160,220 130,180 T 120,150 20,100 Z "> <Path.Fill> <MultiBinding> <MultiBinding.Converter> <local:ProgressBarBrushConverter /> </MultiBinding.Converter> <Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type ProgressBar}}" /> <Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}"/> <Binding Path="Value" RelativeSource="{RelativeSource TemplatedParent}"/> </MultiBinding> </Path.Fill> <!--<Path.LayoutTransform> <RotateTransform Angle="180" CenterX="190" CenterY="110" /> </Path.LayoutTransform>--> </Path> <Rectangle x:Name="PART_Indicator" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="1" /> </Grid> </ControlTemplate> Finally, the Window code (fairly straightforward - it just animates progress from 0 to 100 and back again): <ProgressBar x:Name="progress" Template="{StaticResource customProgressBarTemplate}" Foreground="Red"> <ProgressBar.Triggers> <EventTrigger RoutedEvent="ProgressBar.Loaded"> <BeginStoryboard x:Name="storyAnimate"> <Storyboard> <DoubleAnimationUsingKeyFrames Duration="0:0:12" AutoReverse="True" FillBehavior="Stop" RepeatBehavior="Forever" Storyboard.TargetName="progress" Storyboard.TargetProperty="(ProgressBar.Value)"> <LinearDoubleKeyFrame Value="0" KeyTime="0:0:0" /> <LinearDoubleKeyFrame Value="100" KeyTime="0:0:5" /> <LinearDoubleKeyFrame Value="100" KeyTime="0:0:6" /> <LinearDoubleKeyFrame Value="0" KeyTime="0:0:11" /> <LinearDoubleKeyFrame Value="0" KeyTime="0:0:12" /> </DoubleAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> </ProgressBar.Triggers> </ProgressBar> I am thinking that the problem is in the DrawRectangle call in the Convert method, but setting a TracePoint on it shows what appear to be valid values for the Rect. What am I missing here? Thanks, wTs

• Android: Get the X and Y coordinates of a TextView?

  - by Jep Knopz

  I am working now on a project. I have 2 draggable textView in a circle. I want to add those value inside the circle when the circle is drag over the other circle. the first option that I have is to get the X and Y of the circle, but I get it. Can anyone fix my code? Here is the Code: MainActivity public class MainActivity extends Activity { int windowwidth; int windowheight; TextView bola; TextView bola2; private float x; private float y; private android.widget.RelativeLayout.LayoutParams layoutParams; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); windowwidth = getWindowManager().getDefaultDisplay().getWidth(); windowheight = getWindowManager().getDefaultDisplay().getHeight(); bola = (TextView) findViewById(R.id.ball); bola2 = (TextView) findViewById(R.id.ball2); bola2.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub layoutParams = (RelativeLayout.LayoutParams) bola2 .getLayoutParams(); switch (event.getActionMasked()) { case MotionEvent.ACTION_DOWN: break; case MotionEvent.ACTION_MOVE: int x_cord = (int) event.getRawX(); int y_cord = (int) event.getRawY(); if (x_cord > windowwidth) { x_cord = windowwidth; } if (y_cord > windowheight) { y_cord = windowheight; } layoutParams.leftMargin = x_cord - 25; layoutParams.topMargin = y_cord - 75; bola2.setLayoutParams(layoutParams); break; default: break; } return true; } }); bola.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { layoutParams = (RelativeLayout.LayoutParams) bola .getLayoutParams(); switch (event.getActionMasked()) { case MotionEvent.ACTION_DOWN: break; case MotionEvent.ACTION_MOVE: int x_cord = (int) event.getRawX(); int y_cord = (int) event.getRawY(); if (x_cord > windowwidth) { x_cord = windowwidth; } if (y_cord > windowheight) { y_cord = windowheight; } layoutParams.leftMargin = x_cord - 25; layoutParams.topMargin = y_cord - 75; bola.setLayoutParams(layoutParams); break; default: break; } // TODO Auto-generated method stub return true; } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; }} Activity_main.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:id= "@+id/ball" android:background="@drawable/bgshape" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1" tools:context=".MainActivity" /> <TextView android:id= "@+id/ball2" android:background="@drawable/bgshape" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="2" tools:context=".MainActivity" android:layout_x="60dp" android:layout_y="20dp" /> The bgshape.xml(for the circle) <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <padding android:bottom="20dp" android:left="25dp" android:right="25dp" android:top="20dp" /> <stroke android:width="2dp" android:color="#000000" /> <solid android:color="#ffffff" /> <corners android:bottomLeftRadius="30dp" android:bottomRightRadius="30dp" android:topLeftRadius="30dp" android:topRightRadius="30dp" /> This code works well.

• Is there a way to edit a control's template based on the default template?

  - by Adam S

  I'm trying to make just a few minor tweaks to the default template of a checkbox. Now I understand how to make a new template from scratch, but this I do not know. I did manage to (I think?) extract the default template via the method here. And it spat out: <ControlTemplate TargetType="CheckBox" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mwt="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Luna"> <BulletDecorator Background="#00FFFFFF" SnapsToDevicePixels="True"> <BulletDecorator.Bullet> <mwt:BulletChrome Background="{TemplateBinding Panel.Background}" BorderBrush="{TemplateBinding Border.BorderBrush}" BorderThickness="{TemplateBinding Border.BorderThickness}" RenderMouseOver="{TemplateBinding UIElement.IsMouseOver}" RenderPressed="{TemplateBinding ButtonBase.IsPressed}" IsChecked="{TemplateBinding ToggleButton.IsChecked}" /> </BulletDecorator.Bullet> <ContentPresenter RecognizesAccessKey="True" Content="{TemplateBinding ContentControl.Content}" ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}" ContentStringFormat="{TemplateBinding ContentControl.ContentStringFormat}" Margin="{TemplateBinding Control.Padding}" HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </BulletDecorator> <ControlTemplate.Triggers> <Trigger Property="ContentControl.HasContent"> <Setter Property="FrameworkElement.FocusVisualStyle"> <Setter.Value> <Style TargetType="IFrameworkInputElement"> <Style.Resources> <ResourceDictionary /> </Style.Resources> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Stroke="#FF000000" StrokeThickness="1" StrokeDashArray="1 2" Margin="14,0,0,0" SnapsToDevicePixels="True" /> </ControlTemplate> </Setter.Value> </Setter> </Style> </Setter.Value> </Setter> <Setter Property="Control.Padding"> <Setter.Value> <Thickness>2,0,0,0</Thickness> </Setter.Value> </Setter> <Trigger.Value> <s:Boolean>True</s:Boolean> </Trigger.Value> </Trigger> <Trigger Property="UIElement.IsEnabled"> <Setter Property="TextElement.Foreground"> <Setter.Value> <DynamicResource ResourceKey="{x:Static SystemColors.GrayTextBrushKey}" /> </Setter.Value> </Setter> <Trigger.Value> <s:Boolean>False</s:Boolean> </Trigger.Value> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> Okay, sure, looks just fine I guess. I don't have enough experience to know if that looks like it's right or not. Now, I get two errors: Assembly 'PresentationFramework.Luna' was not found. Verify that you are not missing an assembly reference. Also, verify that your project and all referenced assemblies have been built. and The type 'mwt:BulletChrome' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. Now I'm wondering, how can I resolve these errors so that I can actually start working on the template? Is there a better way of going about this? My boss wants a three-state checkbox with a red square instead of green, and he won't take no for an answer.

• Technology to communicate with someone with expressive aphasia?

  - by rascher

  A family member had a stroke a few years back and now has expressive aphasia. She understands what is said to her, is cognitive of what is going on, but cannot express herself. She is able to respond to yes/no questions (do you want to go shopping? are you looking for your earrings?) She is not, however, able to read (English is not her native language and she hasn't read Hindi for decades.) I am the technologist in the family, and I intend to come up with something to help us communicate. The idea is to have some sort of picture book where she can point to what she wants. My first question: does some sort of assistive technology for people with expressive aphasia already exist? These can be hardware or software devices? If not, then such a software doesn't seem difficult to write. My initial thought is to have an interface with pictures - maybe separated by category (food, shopping) - where she can point to an individual picture to indicate what she needs. We could easily add more items with such a software, and we could have an interface where she (or we) could "flip pages". Which suggests that the best solution would use a touch screen rather than a mouse. It would be really difficult to train her to aim a mouse or find keys on a keyboard. We're thinking of maybe getting a tablet and writing some basic software. But tablets computers are expensive and fragile - I'm not sure if it would be able to stand spills or being knocked about in a nursing home. So my next question: what kind of tablet-like devices are out there which I can program on? I don't know anything about hardware, but if there is something then we could special-order it. What would be safe and durable for such a project? We could do something on an iPod or cell phone, but I feel like that interface would be too small. Finally, does anyone here have experience with this kind of assistive technology? Things I might not anticipate when designing such a system? edit I've added a (pretty hefty!) bounty. I'd kinda like to open this question up to any suggestions, comments, and experiences that people might have. This is a pretty real and important project, so while we will (are working on) a solution, any insights would be particularly helpful. Right now the plan is to mount a screen in her room. We'll either teach her to use a trackball or use a touch-screen panel, after seeing what she is able to use with a simple prototype. Then software akin to an old "hypercard" deck: ---------------------------------------------------------------- | -------------- -------------- | | | Clothes | | Food | ... | | -------------- -------------- | | | | Pic of item 1 Pic of item 2 Pic of item 3 | | | | | | | | | | Pic of item 4 Pic of item 5 Pic of item 6 | | | | | | | | | | <-Back Next-> | ---------------------------------------------------------------- commentcommentcomment!

• CABasicAnimation not scrolling with rest of View

  - by morgman

  All, I'm working on reproducing the pulsing Blue circle effect that the map uses to show your own location... I layered a UIView over a MKMapView. The UIView contains the pulsing animation. I ended up using the following code gleaned from numerous answers here on stackoverflow: CABasicAnimation* pulseAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"]; pulseAnimation.toValue = [NSNumber numberWithFloat: 0.0]; pulseAnimation.duration = 1.0; pulseAnimation.repeatCount = HUGE_VALF; pulseAnimation.autoreverses = YES; pulseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:pulseAnimation forKey:@"pulseAnimation"]; CABasicAnimation* resizeAnimation = [CABasicAnimation animationWithKeyPath:@"bounds.size"]; resizeAnimation.toValue = [NSValue valueWithCGSize:CGSizeMake(0.0f, 0.0f)]; resizeAnimation.fillMode = kCAFillModeBoth; resizeAnimation.duration = 1.0; resizeAnimation.repeatCount = HUGE_VALF; resizeAnimation.autoreverses = YES; resizeAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:resizeAnimation forKey:@"resizeAnimation"]; This does an acceptable job of pulsing/fading a circle I drew in the UIView using: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(context, 1.0, 0.0, 0.0, 0.4); // And draw with a blue fill color CGContextSetRGBFillColor(context, 1.0, 0.0, 0.0, 0.1); // Draw them with a 2.0 stroke width so they are a bit more visible. CGContextSetLineWidth(context, 2.0); CGContextAddEllipseInRect(context, CGRectMake(x-30, y-30, 60.0, 60.0)); CGContextDrawPath(context, kCGPathFillStroke); But I soon found that while this appears to work, as soon as I drag the underlying map to another position the animation screws up... While the position I want highlighted is centered on the screen the animation works ok, once I've dragged the position so it's no longer centered the animation now pulses starting at the center of the screen scaling up to center on the position dragged off center, and back again... A humorous and cool effect, but not what I was looking for. I realize I may have been lucky on several fronts. I'm not sure what I misunderstood. I think the animation is scaling the entire layer which just happens to have my circle drawn in the middle of it. So it works when centered but not when off center. I tried the following gleaned from one of the questions suggested by stackoverflow when I started this question: CABasicAnimation* translateAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; translateAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(oldx, oldy )]; translateAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(x, y )]; // translateAnimation.fillMode = kCAFillModeBoth; translateAnimation.duration = 1.0; translateAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:translateAnimation forKey:@"translateAnimation"]; But it doesn't help much, when I play with it sometimes it looks like once time it animates in the correct spot after I've moved it offcenter, but then it switches back to the animating from the center point to the new location. Sooo, any suggestions or do I need to provide additional information.

• Slow Javascript touch events on Android

  - by oneself

  I'm trying to write a simple html based drawing application (standalone simplified code attached bellow). I've tested this on the following devices: iPad 1 and 2: Works great ASUS T101 running Windows: Works great Samsung Galaxy Tab: Extremely slow and patchy -- unusable. Lenovo IdeaPad K1: Extremely slow and patchy -- unusable. Asus Transformer Prime: Noticeable lag compare with the iPad -- close to usable. The Asus tablet is running ICS, the other android tablets are running 3.1 and 3.2. I tested using the stock Android browser. I also tried the Android Chrome Beta, but that was even worse.

• Can draw on only half of UIView

  - by ydlee777

  Hello. I am trying to draw grid on a UIView on a UIScrollView. The width of UIView is about 1000 pixels. However, I can draw lines only about first 340 pixels of the UIView. Can anyone help me on this? The drawGrid function is - (void)drawRect:(CGRect)rect { NSInteger width = 25 * 5 * 10; NSInteger height = (10 * 2 + 10) * 12; NSInteger i; //Get the CGContext from this view CGContextRef context = UIGraphicsGetCurrentContext(); // Draw rectangle with a blue stroke color and white fill color CGContextSetRGBStrokeColor(context, 0.0, 0.0, 1.0, 1.0); CGContextSetRGBFillColor(context, 0.0, 0.0, 1.0, 1.0); CGContextSetLineWidth(context, 2.0); CGContextAddRect(context, CGRectMake(0.0, 0.0, width, height)); CGContextFillPath(context); // Draw grid with red color CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor); // Set the width of the pen mark CGContextSetLineWidth(context, 0.2); for (i = 0; i < height; i += 5) { if (i % 25 == 0) { CGContextSetLineWidth(context, 0.4); // Draw a line CGContextMoveToPoint(context, i, 0.0); CGContextAddLineToPoint(context, i, width); CGContextStrokePath(context); CGContextSetLineWidth(context, 0.2); } else { // Draw a line CGContextMoveToPoint(context, i, 0.0); CGContextAddLineToPoint(context, i, width); CGContextStrokePath(context); } } for (i = 0; i < width; i += 5) { if (i % 25 == 0) { CGContextSetLineWidth(context, 0.4); // Draw a line CGContextMoveToPoint(context, 0.0, i); CGContextAddLineToPoint(context, height, i); CGContextStrokePath(context); CGContextSetLineWidth(context, 0.2); } else { // Draw a line CGContextMoveToPoint(context, 0.0, i); CGContextAddLineToPoint(context, height, i); CGContextStrokePath(context); } } } I am also setting up the UIScrollView and UIView as follows: - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height); waveScrollView = [[WaveScrollView alloc] initWithFrame:frame]; CGRect waveframe = CGRectMake(0, 0, 25 * 5 * 10, (10 * 2 + 10) * 12); EKGWaveView *ekgWaveView = [[EKGWaveView alloc] initWithFrame:waveframe]; waveScrollView.contentSize = CGSizeMake(waveframe.size.width, waveframe.size.height); waveScrollView.maximumZoomScale = 4.0; waveScrollView.minimumZoomScale = 0.75; waveScrollView.clipsToBounds = YES; waveScrollView.aView = ekgWaveView; [waveScrollView addSubview:ekgWaveView]; waveScrollView.delegate = self; [self.view addSubview:waveScrollView]; } I appreciate any help. Thanks.

• Doing XML extracts with XSLT without having to read the whole DOM tree into memory?

  - by Thorbjørn Ravn Andersen

  I have a situation where I want to extract some information from some very large but regular XML files (just had to do it with a 500 Mb file), and where XSLT would be perfect. Unfortunately those XSLT implementations I am aware of (except the most expensive version of Saxon) does not support only having the necessary part of the DOM read in but reads in the whole tree. This cause the computer to swap to death. The XPath in question is //m/e[contains(.,'foobar') so it is essentially just a grep. Is there an XSLT implementation which can do this? Or an XSLT implementation which given suitable "advice" can do this trick of pruning away the parts in memory which will not be needed again? I'd prefer a Java implementation but both Windows and Linux are viable native platforms. EDIT: The input XML looks like: <log> <!-- Fri Jun 26 12:09:27 CEST 2009 --> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Registering Catalina:type=Manager,path=/axsWHSweb-20090626,host=localhost</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Force random number initialization starting</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Getting message digest component for algorithm MD5</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Completed getting message digest component</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>getDigest() 0</m></e> ...... </log> Essentialy I want to select some m-nodes (and I know the XPath is wrong for that, it was just a quick hack), but maintain the XML layout. EDIT: It appears that STX may be what I am looking for (I can live with another transformation language), and that Joost is an implementation hereof. Any experiences? EDIT: I found that Saxon 6.5.4 with -Xmx1500m could load my XML, so this allowed me to use my XPaths right now. This is just a lucky stroke so I'd still like to solve this generically - this means scriptable which in turn means no handcrafted Java filtering first. EDIT: Oh, by the way. This is a log file very similar to what is generated by the log4j XMLLayout. The reason for XML is to be able to do exactly this, namely do queries on the log. This is the initial try, hence the simple question. Later I'd like to be able to ask more complex questions - therefore I'd like the query language to be able to handle the input file.

• How to change the overlapping order of TabItems in WPF TabControl

  - by sannoble

  I have created vertical TabItems with a Path object. The selected TabItem overlaps the unselected TabItems, this works fine. The overlapping is done by setting a negative margin in the TabItem Template. For the unselected TabItems right now a TabItem is overlapped by the TabItem below. For example in the picture Tab 4 overlaps Tab 3 and Tab 3 overlaps Tab 2. I would like to change the overlapping order for the unselected Tab Items, so that an unselected TabItem overlaps the TabItem below and is overlapped by the TabItem above, e.g. Tab 2 overlaps Tab 3 and Tab 3 overlaps Tab 4. I have tried to set the FlowDirection property of TabPanel, but this doesn't work. How can I achieve this? Any help is appreciated. Thanks in advance! Wrong overlapping of unselected TabItems: XAML-Code: <Style x:Key="styleMainNavTabControl" TargetType="{x:Type TabControl}"> <Setter Property="TabStripPlacement" Value="Left" /> <Setter Property="SnapsToDevicePixels" Value="true"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type TabControl}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="200"/> </Grid.ColumnDefinitions> <Border Grid.Column="0" Background="White" BorderBrush="Black" BorderThickness="0,0,1,0" Padding="20"> <ContentPresenter ContentSource="SelectedContent" /> </Border> <Border Grid.Column="1" Padding="0,30,10,0" Background="#F7F3F7"> <TabPanel Panel.ZIndex="1" Margin="-1,0,0,0" FlowDirection="RightToLeft" IsItemsHost="True" Background="Transparent"/> </Border> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style x:Key="styleMainNavTabItem" TargetType="{x:Type TabItem}"> <Setter Property="MinHeight" Value="90" /> <Setter Property="FontSize" Value="14" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type TabItem}"> <Grid Margin="0,0,0,-35"> <Path Name="TabPath" Stroke="Black" StrokeThickness="1" Fill="LightGray" Data="M 0,0 a 10,10 0 0 0 10,10 h 150 a 20,20 0 0 1 20,20 v 60 a 20,20 0 0 1 -20,20 h -150 a 10,10 0 0 0 -10,10 z" /> <ContentPresenter ContentSource="Header" Margin="10,2,10,2" VerticalAlignment="Center" TextElement.Foreground="#FF000000"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="Panel.ZIndex" Value="100" /> <Setter TargetName="TabPath" Property="Fill" Value="White" /> <Setter TargetName="TabPath" Property="Data" Value="M 0,0 a 10,10 0 0 0 10,10 h 150 a 20,20 0 0 1 20,20 v 60 a 20,20 0 0 1 -20,20 h -150 a 10,10 0 0 0 -10,10" /> </Trigger> <Trigger Property="IsSelected" Value="False"> <Setter Property="Panel.ZIndex" Value="90" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter>

• 10000's+ UI elements, bind or draw?

  - by jpiccolo

  I am drawing a header for a timeline control. It looks like this: I go to 0.01 millisecond per line, so for a 10 minute timeline I am looking at drawing 60000 lines + 6000 labels. This takes a while, ~10 seconds. I would like to offload this from the UI thread. My code is currently: private void drawHeader() { Header.Children.Clear(); switch (viewLevel) { case ViewLevel.MilliSeconds100: double hWidth = Header.Width; this.drawHeaderLines(new TimeSpan(0, 0, 0, 0, 10), 100, 5, hWidth); //Was looking into background worker to off load UI //backgroundWorker = new BackgroundWorker(); //backgroundWorker.DoWork += delegate(object sender, DoWorkEventArgs args) // { // this.drawHeaderLines(new TimeSpan(0, 0, 0, 0, 10), 100, 5, hWidth); // }; //backgroundWorker.RunWorkerAsync(); break; } } private void drawHeaderLines(TimeSpan timeStep, int majorEveryXLine, int distanceBetweenLines, double headerWidth) { var currentTime = new TimeSpan(0, 0, 0, 0, 0); const int everyXLine100 = 10; double currentX = 0; var currentLine = 0; while (currentX < headerWidth) { var l = new Line { ToolTip = currentTime.ToString(@"hh\:mm\:ss\.fff"), StrokeThickness = 1, X1 = 0, X2 = 0, Y1 = 30, Y2 = 25 }; if (((currentLine % majorEveryXLine) == 0) && currentLine != 0) { l.StrokeThickness = 2; l.Y2 = 15; var textBlock = new TextBlock { Text = l.ToolTip.ToString(), FontSize = 8, FontFamily = new FontFamily("Tahoma"), Foreground = new SolidColorBrush(Color.FromRgb(255, 255, 255)) }; Canvas.SetLeft(textBlock, (currentX - 22)); Canvas.SetTop(textBlock, 0); Header.Children.Add(textBlock); } if ((((currentLine % everyXLine100) == 0) && currentLine != 0) && (currentLine % majorEveryXLine) != 0) { l.Y2 = 20; var textBlock = new TextBlock { Text = string.Format(".{0}", TimeSpan.Parse(l.ToolTip.ToString()).Milliseconds), FontSize = 8, FontFamily = new FontFamily("Tahoma"), Foreground = new SolidColorBrush(Color.FromRgb(192, 192, 192)) }; Canvas.SetLeft(textBlock, (currentX - 8)); Canvas.SetTop(textBlock, 8); Header.Children.Add(textBlock); } l.Stroke = new SolidColorBrush(Color.FromRgb(255, 255, 255)); Header.Children.Add(l); Canvas.SetLeft(l, currentX); currentX += distanceBetweenLines; currentLine++; currentTime += timeStep; } } I had looked into BackgroundWorker, except you can't create UI elements on a non-UI thread. Is it possible at all to do drawHeaderLines in a non-UI thread? Could I use data binding for drawing the lines? Would this help with UI responsiveness? I would imagine I can use databinding, but the Styling is probably beyond my current WPF ability (coming from winforms and trying to learn what all these style objects are and binding them). Would anyone be able to supply a starting point for tempting this out? Or Google a tutorial that would get me started?

• Not All “Viruses” Are Viruses: 10 Malware Terms Explained

  - by Chris Hoffman

  Most people seem to call every type of malware a “virus”, but that isn’t technically accurate. You’ve probably heard of many more terms beyond virus: malware, worm, Trojan, rootkit, keylogger, spyware, and more. But what do all these terms mean? These terms aren’t just used by geeks. They make their way into even mainstream news stories about the latest web security problems and tech scares. Understanding them will help you understand the dangers your\ hear about. Malware The word “malware” is short for “malicious software.” Many people use the word “virus” to indicate any type of harmful software, but a virus is actually just a specific type of malware. The word “malware” encompasses all harmful software, including all the ones listed below. Virus Let’s start with viruses. A virus is a type of malware that copies itself by infecting other files,  just as viruses in the real world infect biological cells and use those biological cells to reproduce copies of themselves. A virus can do many different things — watch in the background and steal your passwords, display advertisements, or just crash your computer — but the key thing that makes it a virus is how it spreads. When you run a virus, it will infect programs on your computer. When you run the program on another computer, the virus will infect programs on that computer, and so on. For example, a virus might infect program files on a USB stick. When the programs on that USB stick are run on another computer, the virus runs on the other computer and infects more program files. The virus will continue to spread in this way. Worm A worm is similar to a virus, but it spreads a different way. Rather than infecting files and relying on human activity to move those files around and run them on different systems, a worm spreads over computer networks on its own accord. For example, the Blaster and Sasser worms spread very quickly in the days of Windows XP because Windows XP did not come properly secured and exposed system services to the Internet. The worm accessed these system services over the Internet, exploited a vulnerability, and infected the computer. The worm then used the new infected computer to continue replicating itself. Such worms are less common now that Windows is properly firewalled by default, but worms can also spread in other ways — for example, by mass-emailing themselves to every email address in an effected user’s address book. Like a virus, a worm can do any number of other harmful things once it infects a computer. The key thing that makes it a worm is simply how it spreads copies of itself. Trojan (or Trojan Horse) A Trojan horse, or Trojan, is a type of malware that disguises itself as a legitimate file. When you download and run the program, the Trojan horse will run in the background, allowing third-parties to access your computer. Trojans can do this for any number of reasons — to monitor activity on your computer, to join your computer to a botnet. Trojans may also be used to open the floodgates and download many other types of malware onto your computer. The key thing that makes this type of malware a Trojan is how it arrives. It pretends to be a useful program and, when run, it hides in the background and gives malicious people access to your computer. It isn’t obsessed with copying itself into other files or spreading over the network, as viruses and worms are. For example, a piece of pirated software on an unscrupulous website may actually contain a Trojan. Spyware Spyware is a type of malicious software that spies on you without your knowledge. It collects a variety of different types of data, depending on the piece of spyware. Different types of malware can function as spyware — there may be malicious spyware included in Trojans that spies on your keystrokes to steal financial data, for example. More “legitimate” spyware may be bundled along with free software and simply monitor your web browsing habits, uploading this data to advertising servers so the software’s creator can make money from selling their knowledge of your activities. Adware Adware often comes along with spyware. It’s any type of software that displays advertising on your computer. Programs that display advertisements inside the program itself aren’t generally classified as malware. The kind of “adware” that’s particularly malicious is the kind that abuses its access to your system to display ads when it shouldn’t. For example, a piece of harmful adware may cause pop-up advertisements to appear on your computer when you’re not doing anything else. Or, adware may inject additional advertising into other web pages as you browse the web. Adware is often combined with spyware — a piece of malware may monitor your browsing habits and use them to serve you more targeted ads. Adware is more “socially acceptable” than other types of malware on Windows and you may see adware bundled with legitimate programs. For example, some people consider the Ask Toolbar included with Oracle’s Java software adware. Keylogger A keylogger is a type of malware that runs in the background, recording every key stroke you make. These keystrokes can include usernames, passwords, credit card numbers, and other sensitive data. The keylogger then, most likely, uploads these keystrokes to a malicious server, where it can be analyzed and people can pick out the useful passwords and credit card numbers. Other types of malware can act as keyloggers. A virus, worm, or Trojan may function as a keylogger, for example. Keyloggers may also be installed for monitoring purposes by businesses or even jealous spouses. Botnet, Bot A botnet is a large network of computers that are under the botnet creator’s control. Each computer functions as a “bot” because it’s infected with a specific piece of malware. Once the bot software infects the computer, ir will connect to some sort of control server and wait for instructions from the botnet’s creator. For example, a botnet may be used to initiate a DDoS (distributed denial of service) attack. Every computer in the botnet will be told to bombard a specific website or server with requests at once, and such millions or requests can cause a server to become unresponsive or crash. Botnet creators may sell access to their botnets, allowing other malicious individuals to use large botnets to do their dirty work. Rootkit A rootkit is a type of malware designed to burrow deep into your computer, avoiding detection by security programs and users. For example, a rootkit might load before most of Windows, burying itself deep into the system and modifying system functions so that security programs can’t detect it. A rootkit might hide itself completely, preventing itself from showing up in the Windows task manager. The key thing that makes a type of malware a rootkit is that it’s stealthy and focused on hiding itself once it arrives. Ransomware Ransomware is a fairly new type of malware. It holds your computer or files hostage and demands a ransom payment. Some ransomware may simply pop up a box asking for money before you can continue using your computer. Such prompts are easily defeated with antivirus software. More harmful malware like CryptoLocker literally encrypts your files and demands a payment before you can access them. Such types of malware are dangerous, especially if you don’t have backups. Most malware these days is produced for profit, and ransomware is a good example of that. Ransomware doesn’t want to crash your computer and delete your files just to cause you trouble. It wants to take something hostage and get a quick payment from you. So why is it called “antivirus software,” anyway? Well, most people continue to consider the word “virus” synonymous with malware as a whole. Antivirus software doesn’t just protect against viruses, but against all types of malware. It may be more accurately referred to as “antimalware” or “security” software.

• When Your Boss Doesn't Want you to Succeed

  - by Phil Factor

  You're working hard to get an application finished. You are programming long into the evenings sometimes, and eating sandwiches at your desk instead of taking a lunch break. Then one day you glance up at the IT manager, serene in his mysterious round of meetings, and think 'Does he actually care whether this project succeeds or not?'. The question may seem absurd. Of course the project must succeed. The truth, as always, is often far more complex. Your manager may even be doing his best to make sure you don't succeed. Why? There have always been rich pickings for the unscrupulous in IT.  In extreme cases, where administrators struggle with scarcely-comprehended technical issues, huge sums of money can be lost and gained without any perceptible results. In a very few cases can fraud be proven: most of the time, the intricacies of the 'game' are such that one can do little more than harbor suspicion.  Where does over-enthusiastic salesmanship end and fraud begin? The Business of Information Technology provides rich opportunities for White-collar crime. The poor developer has his, or her, hands full with the task of wrestling with the sheer complexity of building an application. He, or she, has no time for following the complexities of the chicanery of the management that is directing affairs.  Most likely, the developers wouldn't even suspect that their company management had ulterior motives. I'll illustrate what I mean with an entirely fictional, hypothetical, example. The Opportunist and the Aged Charities often do good, unexciting work that is funded by the income from a bequest that dates back maybe hundreds of years.  In our example, it isn't exciting work, for it involves the welfare of elderly people who have fallen on hard times.  Volunteers visit, giving a smile and a chat, and check that they are all right, but are able to spend a little money on their discretion to ameliorate any pressing needs for these old folk.  The money is made to work very hard and the charity averts a great deal of suffering and eases the burden on the state. Daisy hears the garden gate creak as Mrs Rainer comes up the path. She looks forward to her twice-weekly visit from the nice lady from the trust. She always asked ‘is everything all right, Love’. Cheeky but nice. She likes her cheery manner. She seems interested in hearing her memories, and talking about her far-away family. She helps her with those chores in the house that she couldn’t manage and once even paid to fill the back-shed with coke, the other year. Nice, Mrs. Rainer is, she thought as she goes to open the door. The trustees are getting on in years themselves, and worry about the long-term future of the charity: is it relevant to modern society? Is it likely to attract a new generation of workers to take it on. They are instantly attracted by the arrival to the board of a smartly dressed University lecturer with the ear of the present Government. Alain 'Stalin' Jones is earnest, persuasive and energetic. The trustees welcome him to the board and quickly forgive his humorless political-correctness. He talks of 'diversity', 'relevance', 'social change', 'equality' and 'communities', but his eye is on that huge bequest. Alain first came to notice as a Trotskyite union official, who insinuated himself into one of the duller Trades Unions and turned it, through his passionate leadership, into a radical, headline-grabbing organization.  Middle age, and the rise of European federal socialism, had brought him quiet prosperity and charcoal suits, an ear in the current government, and a wide influence as a member of various Quangos (government bodies staffed by well-paid unelected courtiers).  He was employed as a 'consultant' by several organizations that relied on government contracts. After gaining the confidence of the trustees, and showing a surprising knowledge of mundane processes and the regulatory framework of charities, Alain launches his plan.  The trust will expand their work by means of a bold IT initiative that will coordinate the interventions of several 'caring agencies', and provide  emergency cover, a special Website so anxious relatives can see how their elderly charges are doing, and a vastly more efficient way of coordinating the work of the volunteer carers. It will also provide a special-purpose site that gives 'social networking' facilities, rather like Facebook, to the few elderly folk on the lists with access to the internet. The trustees perk up. Their own experience of the internet is restricted to the occasional scanning of railway timetables, but they can see that it is 'relevant'. In his next report to the other trustees, Alain proudly announces that all this glamorous and exciting technology can be paid for by a grant from the government. He admits darkly that he has influence. True to his word, the government promises a grant of a size that is an order of magnitude greater than any budget that the trustees had ever handled. There was the understandable proviso that the company that would actually do the IT work would have to be one of the government's preferred suppliers and the work would need to be tendered under EU competition rules. The only company that tenders, a multinational IT company with a long track record of government work, quotes ten million pounds for the work. A trustee questions the figure as it seems enormous for the reasonably trivial internet facilities being built, but the IT Salesmen dazzle them with presentations and three-letter acronyms until they subside into quiescent acceptance. After all, they can’t stay locked in the Twentieth century practices can they? The work is put in hand with a large project team, in a splendid glass building near west London. The trustees see rooms of programmers working diligently at screens, and who talk with enthusiasm of the project. Paul, the project manager, looked through his resource schedule with growing unease. His initial excitement at being given his first major project hadn’t lasted. He’d been allocated a lackluster team of developers whose skills didn’t seem right, and he was allowed only a couple of contractors to make good the deficit. Strangely, the presentation he’d given to his management, where he’d saved time and resources with a OTS solution to a great deal of the development work, and a sound conservative architecture, hadn’t gone down nearly as big as he’d hoped. He almost got the feeling they wanted a more radical and ambitious solution. The project starts slipping its dates. The costs build rapidly. There are certain uncomfortable extra charges that appear, such as the £600-a-day charge by the 'Business Manager' appointed to act as a point of liaison between the charity and the IT Company.  When he appeared, his face permanently split by a 'Mr Sincerity' smile, they'd thought he was provided at the cost of the IT Company. Derek, the DBA, didn’t have to go to the server room quite some much as he did: but It got him away from the poisonous despair of the development group. Wave after wave of events had conspired to delay the project.  Why the management had imposed hideous extra bureaucracy to cover ISO 9000 and 9001:2008 accreditation just as the project was struggling to get back on-schedule was  beyond belief.  Then  the Business manager was coming back with endless changes in scope, sorrowing saying that the Trustees were very insistent, though hopelessly out in touch with the reality of technical challenges. Suddenly, the costs mount to the point of consuming the government grant in its entirety. The project remains tantalizingly just out of reach. Alain Jones gives an emotional rallying speech at the trustees review meeting, urging them not to lose their nerve. Sadly, the trustees dip into the accumulated capital of the trust, the seed-corn of all their revenues, in order to save the IT project. A few months later it is all over. The IT project is never delivered, even though it had seemed so incredibly close.  With the trust's capital all gone, the activities it funded have to be terminated and the trust becomes just a shell. There aren't even the funds to mount a legal challenge against the IT company, even had the trust's solicitor advised such a foolish thing. Alain leaves as suddenly as he had arrived, only to pop up a few months later, bronzed and rested, at another charity. The IT workers who were permanent employees are dispersed to other projects, and the contractors leave to other contracts. Within months the entire project is but a vague memory. One or two developers remain  puzzled that their managers had been so obstructive when they should have welcomed progress toward completion of the project, but they put it down to incompetence and testosterone. Few suspected that they were actively preventing the project from getting finished. The relationships between the IT consultancy, and the government of the day are intricate, and made more complex by the Private Finance initiatives and political patronage.  The losers in this case were the taxpayers, and the beneficiaries of the trust, and, perhaps the soul of the original benefactor of the trust, whose bid to give his name some immortality had been scuppered by smooth-talking white-collar political apparatniks.  Even now, nobody is certain whether a crime was ever committed. The perfect heist, I guess. Where’s the victim? "I hear that Daisy’s cottage is up for sale. She’s had to go into a care home.  She didn’t want to at all, but then there is nobody to keep an eye on her since she had that minor stroke a while back.  A charity used to help out. The ‘social’ don’t have the funding, evidently for community care. Yes, her old cat was put down. There was a good clearout, and now the house is all scrubbed and cleared ready for sale.

• Animation Color [on hold]

  - by user2425429

  I'm having problems in my java program for animation. I'm trying to draw a hexagon with a shape similar to that of a trapezoid. Then, I'm making it move to the right for a certain amount of time (DEMO_TIME). Animation and ScreenManager are "API" classes, and AnimationTest1 is a demo. In my test program, it runs with a black screen and white stroke color. I'd like to know why this happened and how to fix it. I'm a beginner, so I apologize for this question being stupid to all you game programmers. Here is the code I have now: import java.awt.DisplayMode; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Image; import java.awt.Polygon; import java.util.ArrayList; import java.util.List; import java.util.concurrent.Executor; import java.util.concurrent.Executors; import javax.swing.ImageIcon; public class AnimationTest1 { public static void main(String args[]) { AnimationTest1 test = new AnimationTest1(); test.run(); } private static final DisplayMode POSSIBLE_MODES[] = { new DisplayMode(800, 600, 32, 0), new DisplayMode(800, 600, 24, 0), new DisplayMode(800, 600, 16, 0), new DisplayMode(640, 480, 32, 0), new DisplayMode(640, 480, 24, 0), new DisplayMode(640, 480, 16, 0) }; private static final long DEMO_TIME = 4000; private ScreenManager screen; private Image bgImage; private Animation anim; public void loadImages() { // create animation List<Polygon> polygons=new ArrayList(); int[] x=new int[]{20,4,4,20,40,56,56,40}; int[] y=new int[]{20,32,40,44,44,40,32,20}; polygons.add(new Polygon(x,y,8)); anim = new Animation(); //# of frames long startTime = System.currentTimeMillis(); long currTimer = startTime; long elapsedTime = 0; boolean animated = false; Graphics2D g = screen.getGraphics(); int width=200; int height=200; while (currTimer - startTime < DEMO_TIME*2) { //draw the polygons if(!animated){ for(int j=0; j<polygons.size();j++){ for(int pos=0; pos<polygons.get(j).npoints; pos++){ polygons.get(j).xpoints[pos]+=1; } } anim.setNewPolyFrame(polygons , width , height , 64); } else{ // update animation anim.update(elapsedTime); draw(g); g.dispose(); screen.update(); try{ Thread.sleep(20); } catch(InterruptedException ie){} } if(currTimer - startTime == DEMO_TIME) animated=true; elapsedTime = System.currentTimeMillis() - currTimer; currTimer += elapsedTime; } } public void run() { screen = new ScreenManager(); try { DisplayMode displayMode = screen.findFirstCompatibleMode(POSSIBLE_MODES); screen.setFullScreen(displayMode); loadImages(); } finally { screen.restoreScreen(); } } public void draw(Graphics g) { // draw background g.drawImage(bgImage, 0, 0, null); // draw image g.drawImage(anim.getImage(), 0, 0, null); } } ScreenManager: import java.awt.Color; import java.awt.DisplayMode; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.GraphicsConfiguration; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Toolkit; import java.awt.Window; import java.awt.event.KeyListener; import java.awt.event.MouseListener; import java.awt.image.BufferStrategy; import java.awt.image.BufferedImage; import javax.swing.JFrame; import javax.swing.JPanel; public class ScreenManager extends JPanel { private GraphicsDevice device; /** Creates a new ScreenManager object. */ public ScreenManager() { GraphicsEnvironment environment=GraphicsEnvironment.getLocalGraphicsEnvironment(); device = environment.getDefaultScreenDevice(); setBackground(Color.white); } /** Returns a list of compatible display modes for the default device on the system. */ public DisplayMode[] getCompatibleDisplayModes() { return device.getDisplayModes(); } /** Returns the first compatible mode in a list of modes.

Thanks in advance <ResourceDictionary> <LinearGradientBrush x:Key="Stroke_Gradient" EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="#FF6E6E6E" Offset="0"/> <GradientStop Color="#FFFFFFFF" Offset="0.496"/> <GradientStop Color="#FF6E6E6E" Offset="1"/> </LinearGradientBrush> <Style x:Key="ScrollBar_RepeatButtonStyle1" d:IsControlPart="True" TargetType="{x:Type RepeatButton}"> <Setter Property="Background" Value="#FF6E6E6E"/> <Setter Property="BorderBrush" Value="#FFFFFFFF"/> <Setter Property="IsTabStop" Value="false"/> <Setter Property="Focusable" Value="false"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type RepeatButton}"> <Grid> <Rectangle Fill="{TemplateBinding Background}" Stroke="{TemplateBinding BorderBrush}" StrokeThickness="{TemplateBinding BorderThickness}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> <ImageBrush x:Key="zoomBkgrnd" TileMode="None" ImageSource="zoombg.png" Stretch="Uniform"/> <Style x:Key="{x:Type Slider}" TargetType="{x:Type Slider}"> <Setter Property="Background" Value="{StaticResource zoomBkgrnd}"/> <Setter Property="BorderBrush" Value="{StaticResource zoomBkgrnd}"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Slider}"> <Grid x:Name="GridRoot"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <!-- TickBar shows the ticks for Slider --> <TickBar Visibility="Collapsed" x:Name="TopTick" Height="4" SnapsToDevicePixels="True" Placement="Top" Fill="{StaticResource zoomBkgrnd}"/> <Border Grid.Row="1" Margin="0" x:Name="Border" Height="4" Background="{StaticResource zoomBkgrnd}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="2"/> <!-- The Track lays out the repeat buttons and thumb --> <Track Grid.Row="1" x:Name="PART_Track"> <Track.Thumb> <Thumb Width="10" Height="20" /> </Track.Thumb> <Track.IncreaseRepeatButton> <RepeatButton Style="{DynamicResource ScrollBar_RepeatButtonStyle1}" Command="Slider.IncreaseLarge"/> </Track.IncreaseRepeatButton> <Track.DecreaseRepeatButton> <RepeatButton Style="{DynamicResource ScrollBar_RepeatButtonStyle1}" Command="Slider.DecreaseLarge"/> </Track.DecreaseRepeatButton> </Track> <TickBar Visibility="Collapsed" Grid.Row="2" x:Name="BottomTick" Height="4" SnapsToDevicePixels="True" Placement="Bottom" Fill="{TemplateBinding Foreground}"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="TickPlacement" Value="TopLeft"> <Setter Property="Visibility" Value="Visible" TargetName="TopTick"/> </Trigger> <Trigger Property="TickPlacement" Value="BottomRight"> <Setter Property="Visibility" Value="Visible" TargetName="BottomTick"/> </Trigger> <Trigger Property="TickPlacement" Value="Both"> <Setter Property="Visibility" Value="Visible" TargetName="TopTick"/> <Setter Property="Visibility" Value="Visible" TargetName="BottomTick"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Background" Value="{StaticResource zoomBkgrnd}" TargetName="Border"/> <Setter Property="BorderBrush" Value="{StaticResource zoomBkgrnd}" TargetName="Border"/> </Trigger> <!-- Use a rotation to create a Vertical Slider form the default Horizontal --> <Trigger Property="Orientation" Value="Vertical"> <Setter Property="LayoutTransform" TargetName="GridRoot"> <Setter.Value> <RotateTransform Angle="-90"/> </Setter.Value> </Setter> <!-- Track rotates itself based on orientation so need to force it back --> <Setter TargetName="PART_Track" Property="Orientation" Value="Horizontal"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary>
