Simple Physics Simulation in java not working.

- by Static Void Main

Dear experts, I wanted to implement ball physics and as i m newbie, i adapt the code in tutorial http://adam21.web.officelive.com/Documents/JavaPhysicsTutorial.pdf . i try to follow that as i much as i can, but i m not able to apply all physical phenomenon in code, can somebody please tell me, where i m mistaken or i m still doing some silly programming mistake. The balls are moving when i m not calling bounce method and i m unable to avail the bounce method and ball are moving towards left side instead of falling/ending on floor**, Can some body recommend me some better way or similar easy compact way to accomplish this task of applying physics on two ball or more balls with interactivity. here is code ; import java.awt.*; public class AdobeBall { protected int radius = 20; protected Color color; // ... Constants final static int DIAMETER = 40; // ...

drop down menu will not display outside containing div in IE7..

- by playahabana

I am tearing my hair out over this, I have a dropdown menu using CSS and jQuery (thanks to Soh Tanaka) and it works perfectly in Firefox, Safari, Google chrome and I.E. 8, but in IE 7 it will not drop down outside the 'Banner div'. It drops below the nav div however. I have moved the nav div higher in the banner the result is the same, menu drops until it reaches the border of the banner div and then vanishes.... Below is the css. This is my first website and I have some limited understanding of what I am doing. The drop down menu includes transparent png's as links (I know, I know...but it's what the Boss wants...) please could someone take a quick scan at the below CSS and let me know what is wroong? Is this some form of the IE z-index bug? i have tried all different combinations of z-index and still I can't get a different result. . The html is below as well. Thankyou in advance #banner { position: relative; width: 62.5em; height: 12em; background-color: #46280A; background-image: url('images/includes/banner2.jpg'); background-repeat: no-repeat; background-position: center; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index: 1; } /*------------------------------------SCROLLER---------------------------------------------*/ #headlines{ position: absolute; top: 1.3em; right: 2.75em; overflow: hidden; height: 2.5em; width: 24em; background-color: #000000; display: block; z-index: 3; } #news{ position: relative; height: 3.1em; line-height: 2.5em; font-size: 0.8em color: #FFFF99; white-space: nowrap; overflow: hidden; font-family: Georgia,Arial; } #scrollerglass{ position: absolute; top: 0.95em; right: 2em; height: 52px; width: 410px; border: none; padding: 0.2em 0em 0em 0em; line-height: 0.7em; text-align: center; background-image: url('images/includes/scrollerglass.png'); background-color: transparent; background-repeat: no-repeat; background-position: center; opacity: 20; z-index: 10; } #scrollerglass a i { visibility: hiddn ; } /-------------------------------------NAVIGATION-----------------------------------------/ #nav { position: absolute; top: 5.8em; left: 0.2em; font-family: trebuchet, sans-serif; font-size: 1em; line-height: 3.75em; text-align: center; color: #FFFF00; z-index: 3; } ul.navlist { list-style: none; padding: 0em; margin: 1em; float: left; width: 62.5em; background: transparent; font-size: 1em; } ul.navlist li { position: relative; /*--Declare X and Y axis base for sub navigation--*/ float: left; margin: 0em 1.4em; padding: 0em 0.7em 0em 0em; z-index: 1; } ul.navlist li a{ display: block; text-decoration: none; float: left; border: 0px solid; } ul.navlist li img{ border: 0px solid; } ul.navlist li span { trigger styles--*/ width: 1.2em; height: 5.25em; float: left; background: url(images/links/downlogo.png) no-repeat center top; } ul.navlist li span.subhover { background-position: center bottom; cursor: pointer; } ul.navlist li ul.navdrop { list-style: none; position: absolute; float: left; top: 5.3em; left: -2.4em; height: 15.0em; width: 11.25em; margin: 0; padding: 0.5em 0em 0em 0em; display: none; background-position: center; background-image: url('images/includes/slider.jpg'); background-color: transparent; background-repeat: no-repeat; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index:1; } ul.navlist li ul.navdrop li{ margin: 0em 2.3em 0em 0em; padding: 1em 0em 0em 0em; width: 8em; clear: both; } html ul.navlist li ul.navdrop li a { border: 0px solid; width: 11.25em; } html ul.navlist li ul.navdrop li a:hover { background: transparent; } <div id="banner"> <div id="headlines"> <div id="news"> Whatever we want to promote </div> </div> <div id="scrollerglass"> <a href="vintagecigars.php"> <i>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s--------<br /> <br>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s------</i></a> </div> <div id="nav"> <ul class="navmenu"> <li><a href="index.php"><img src="images/links/home.png" alt="Home" ></a></li> <li><a href="ourbar.php"><img src="images/links/ourbar.png" alt="Our Bar" ></a> <ul class="navdrop"> <li ><a href="ourcocktails.php"><img src="images/links/cockteles.png" alt="Our Cocktails" ></a></li> <li ><a href="celebrate.php"><img src="images/links/celebrate.png" alt="Celebrate in Style" ></a></li> </ul> </li> <li><a href="ourcigars.php"><img src="images/links/ourcigars.png" alt="Our Cigars" ></a> <ul class="navdrop"> <li ><a href="edicioneslimitadas.php"><img src="images/links/edicioneslimitadas.png" alt="Edition Limitadas" ></a></li> <li ><a href="cigartasting.php"><img src="images/links/cigartasting.png" alt="Cigar Tastings" ></a></li> </ul> </li> <li><a href="personalroller.php"><img src="images/links/personalcigar.png" alt="Personal Cigar Roller" ></a></li> <li><a href="galleryentrance.php"><img src="images/links/photogallery.png" alt="Photo Gallery" ></a></li> <li><a href="contactus.php"><img src="images/links/contactus.png" alt="Contact Us" ></a></li> </ul></div></div>

WPF TreeView MouseDown

- by imekon

I've got something like this in a TreeView: <DataTemplate x:Key="myTemplate"> <StackPanel MouseDown="OnItemMouseDown"> ... </StackPanel> </DataTemplate> Using this I get the mouse down events if I click on items in the stack panel. However... there seems to be another item behind the stack panel that is the TreeViewItem - it's very hard to hit, but not impossible, and that's when the problems start to occur. I had a go at handling PreviewMouseDown on TreeViewItem, however that seems to require e.Handled = false otherwise standard tree view behaviour stops working. Ok, Here's the source code...

They make sure the TextBlock is displayed when not editing, and the TextBox is displayed when editing.

change height in Android 2.2 LinearLayout in code

- by Niro

Im trying to change height of Layouts through the code without success. I've tried all of the examples i saw here and other site and my app just keep shutting down. xml code: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/main_lay" android:orientation="vertical" tools:context=".MainActivity" > <LinearLayout android:id="@+id/layout_add" > </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="50dp" android:background="@color/green"> <ImageView android:layout_width="fill_parent" android:contentDescription="@string/desc" android:layout_height="45dp" android:layout_gravity="center_vertical|left" android:scaleType="fitStart" android:background="@color/orange" android:src="@drawable/logo" > </ImageView> </LinearLayout> </LinearLayout> Java code: main_layout=(LinearLayout)findViewById(R.id.main_lay); main_layout.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT)); main_layout.setBackgroundResource(R.color.white); layout_add = (LinearLayout) findViewById(R.id.layout_add); layout_add.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT,50 )); layout_add.setBackgroundResource(R.color.dark_grey); I cant understand what im doing wrong. I've tried different ways to fix it. The Backround setting is working fine.

Things you can draw with HTML tables

- by Coronatus

So I was watching a talk by Google's Marissa Mayer about speeding up Google's pages. They found that a shopping cart icon increased load time by 2%, and users then searched 2% less. They managed to replace the icon with an HTML table. Here is my attempt at drawing a shopping cart: (live example page) <html> <head> <style> table {border-collapse: collapse;} th, td {width: 8px; height: 8px;} th {background-color: blue;} td {background-color: white;} </style> </head> <body> <table>  <tr> <td></td><td></td><td></td><td></td><td></td> <td></td><td></td><td></td><td></td><td></td> <td></td><td></td><td></td><td></td><td></td> <td></td><td></td><td></td><td></td><td></td> </tr>  <tr> <td colspan="14"></td> <th colspan="3"></th> <td colspan="3"></td> </tr> <tr> <td colspan="13"></td> <th colspan="2"></th> <td colspan="1"></td> <th colspan="2"></th> <td colspan="2"></td> </tr> <tr> <td colspan="13"></td> <th colspan="2"></th> <td colspan="1"></td> <th colspan="2"></th> <td colspan="2"></td> </tr> <tr> <td colspan="14"></td> <th colspan="3"></th> <td colspan="3"></td> </tr>  <tr> <td colspan="5"></td> <th colspan="13"></th> <td colspan="2"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="2"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="3"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="2"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="3"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="2"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="3"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="2"></td> </tr> <tr> <td colspan="5"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <td colspan="1"></td> <th colspan="1"></th> <th colspan="1"></th> <td colspan="3"></td> </tr> <tr> <td colspan="5"></td> <th colspan="13"></th> <td colspan="2"></td> </tr>  <tr> <td colspan="7"></td> <th colspan="2"></th> <td colspan="4"></td> <th colspan="2"></th> <td colspan="5"></td> </tr> <tr> <td colspan="6"></td> <th colspan="4"></th> <td colspan="2"></td> <th colspan="4"></th> <td colspan="4"></td> </tr> <tr> <td colspan="7"></td> <th colspan="2"></th> <td colspan="4"></td> <th colspan="2"></th> <td colspan="5"></td> </tr> </table> </body> </html> What can you draw in tables?!

Scriptaculous Shaking Effect Problem

The scriptaculous shaking effect somehow produce some bugs for Webkit browsers, including Chrome and Safari. When shaking, the element will shift to the top left of the screen covering everything.

trouble running smooth animation in thread only when using key listener

- by heysuse renard

first time using a forum for coding help so sorry if i post this all wrong. i have more than a few classes i don't think screenManger or core holds the problem but i included them just incase. i got most of this code working through a set of tutorials. but a certain point started trying to do more on my own. i want to play the animation only when i'm moving my sprite. in my KeyTest class i am using threads to run the animation it used to work (poorly) but now not at all pluss it really gunks up my computer. i think it's because of the thread. im new to threads so i'm not to sure if i should even be using one in this situation or if its dangerous for my computer. the animation worked smoothly when i had the sprite bouce around the screen forever. the animation loop played with out stopping. i think the main problem is between the animationThread, Sprite, and keyTest classes, but itcould be more indepth. if someone could point me in the right direction for making the animation run smoothly when i push down a key and stop runing when i let off it would be greatly apriciated. i already looked at this Java a moving animation (sprite) obviously we were doing the same tutorial. but i feel my problem is slightly different. p.s. sorry for the typos. import java.awt.*;

WPF storyboard animation issue when using VisualBrush

- by Flack

Hey guys, I was playing around with storyboards, a flipping animation, and visual brushes. I have encountered an issue though. Below is the xaml and code-behind of a small sample I quickly put together to try to demonstrate the problem. When you first start the app, you are presented with a red square and two buttons. If you click the "Flip" button, the red square will "flip" over and a blue one will appear. In reality, all that is happening is that the scale of the width of the StackPanel that the red square is in is being decreased until it reaches zero and then the StackPanel where a blue square is, whose width is initially scaled to zero, has its width increased. If you click the "Flip" button a few times, the animation looks ok and smooth. Now, if you hit the "Reflection" button, a reflection of the red/blue buttons is added to their respective StackPanels. Hitting the "Flip" button now will still cause the flip animation but it is no longer a smooth animation. The StackPanels width often does not shrink to zero. The width shrinks somewhat but then just stops before being completely invisible. Then the other StackPanel appears as usual. The only thing that changed was adding the reflection, which is just a VisualBrush. Below is the code. Does anyone have any idea why the animations are different between the two cases (stalling in the second case)? Thanks. <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xml:lang="en-US" xmlns:d="http://schemas.microsoft.com/expression/blend/2006" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="WpfFlipTest.Window1" x:Name="Window" Title="Window1" Width="214" Height="224"> <Window.Resources> <Storyboard x:Key="sbFlip"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="redStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.4" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.4" Storyboard.TargetName="blueStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.8" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="sbFlipBack"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="blueStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.4" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.4" Storyboard.TargetName="redStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.8" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Grid x:Name="LayoutRoot" Background="Gray"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <StackPanel Name="redStack" Grid.Row="0" Grid.Column="0" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform/> </StackPanel.RenderTransform> <Border Name="redBorder" BorderBrush="Transparent" BorderThickness="4" Width="Auto" Height="Auto"> <Button Margin="0" Name="redButton" Height="75" Background="Red" Width="105" /> </Border> <Border Width="{Binding ElementName=redBorder, Path=ActualWidth}" Height="{Binding ElementName=redBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent" BorderThickness="4" Name="redRefelction" Visibility="Collapsed"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=redButton}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <StackPanel Name="blueStack" Grid.Row="0" Grid.Column="0" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform ScaleX="0"/> </StackPanel.RenderTransform> <Border Name="blueBorder" BorderBrush="Transparent" BorderThickness="4" Width="Auto" Height="Auto"> <Button Grid.Row="0" Grid.Column="1" Margin="0" Width="105" Background="Blue" Name="blueButton" Height="75"/> </Border> <Border Width="{Binding ElementName=blueBorder, Path=ActualWidth}" Height="{Binding ElementName=blueBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent" BorderThickness="4" Name="blueRefelction" Visibility="Collapsed"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=blueButton}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <Button Grid.Row="1" Click="FlipButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Flip</Button> <Button Grid.Row="0" Grid.Column="1" Click="ReflectionButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Reflection</Button> </Grid> </Window> Here are the button click handlers: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System.Windows.Media.Animation; namespace WpfFlipTest { public partial class Window1 : Window { public Window1() { InitializeComponent(); } bool flipped = false; private void FlipButton_Click(object sender, RoutedEventArgs e) { Storyboard sbFlip = (Storyboard)Resources["sbFlip"]; Storyboard sbFlipBack = (Storyboard)Resources["sbFlipBack"]; if (flipped) { sbFlipBack.Begin(); flipped = false; } else { sbFlip.Begin(); flipped = true; } } bool reflection = false; private void ReflectionButton_Click(object sender, RoutedEventArgs e) { if (reflection) { reflection = false; redRefelction.Visibility = Visibility.Collapsed; blueRefelction.Visibility = Visibility.Collapsed; } else { reflection = true; redRefelction.Visibility = Visibility.Visible; blueRefelction.Visibility = Visibility.Visible; } } } } UPDATE: I have been testing this some more to try to find out what is causing the issue I am seeing and I believe I found what is causing the issue. Below I have pasted new xaml and code-behind. The new sample below is very similar to the original sample, with a few minor modifications. The xaml basically consists of two stack panels, each containing two borders. The second border in each stack panel is a visual brush (a reflection of the border above it). Now, when I click the "Flip" button, one stack panel gets its ScaleX reduced to zero, while the second stack panel, whose initial ScaleX is zero, gets its ScaleX increased to 1. This animation gives the illusion of flipping. There are also two textblocks which display the scale factor of each stack panel. I added those to try to diagnose my issue. The issue is (as described in the oringal post) that the flipping animation is not smooth. Every time I hit the flip button, the animation starts but whenever the ScaleX factor gets to around .14 to .16, the animation looks like it stalls and the stack panels never have there ScaleX reduced to zero, so they never totally disappear. Now, the strange thing is that if I change the Width/Height properties of the "frontBorder" and "backBorder" borders defined below to use explict values instead of Auto, such as Width=105 and Height=75 (to match the button in the border) everything works fine. The animation stutters the first two or three times I run it but after that the flips are smooth and flawless. (BTW, when an animation is run for the first time, is there something going on in the background, some sort of initialization, that causes it to be a little slow the first time?) Is it possible that the Auto Width/Height of the borders are causing the issue? I can reproduce it everytime but I am not sure why Auto Width/Height would be a problem. Below is the sample. Thanks for the help. <Window x:Class="FlipTest.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> <Storyboard x:Key="sbFlip"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="front" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.5" Storyboard.TargetName="back" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="sbFlipBack"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="back" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.5" Storyboard.TargetName="front" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Grid x:Name="LayoutRoot" Background="White" ShowGridLines="True"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <StackPanel x:Name="front" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform/> </StackPanel.RenderTransform> <Border Name="frontBorder" BorderBrush="Yellow" BorderThickness="2" Width="Auto" Height="Auto"> <Button Margin="0" Name="redButton" Height="75" Background="Red" Width="105" Click="FlipButton_Click"/> </Border> <Border Width="{Binding ElementName=frontBorder, Path=ActualWidth}" Height="{Binding ElementName=frontBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=frontBorder}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <StackPanel x:Name="back" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform ScaleX="0"/> </StackPanel.RenderTransform> <Border Name="backBorder" BorderBrush="Yellow" BorderThickness="2" Width="Auto" Height="Auto"> <Button Margin="0" Width="105" Background="Blue" Name="blueButton" Height="75" Click="FlipButton_Click"/> </Border> <Border Width="{Binding ElementName=backBorder, Path=ActualWidth}" Height="{Binding ElementName=backBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=backBorder}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <Button Grid.Row="1" Click="FlipButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Flip</Button> <TextBlock Grid.Row="2" Grid.Column="0" Foreground="DarkRed" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76" Text="{Binding ElementName=front, Path=(UIElement.RenderTransform).(ScaleTransform.ScaleX)}"/> <TextBlock Grid.Row="3" Grid.Column="0" Foreground="DarkBlue" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76" Text="{Binding ElementName=back, Path=(UIElement.RenderTransform).(ScaleTransform.ScaleX)}"/> </Grid> </Window> Code-behind: using System;

I still fight with some jquery scripts:) With my first problem Jens Fahnenbruck helped me here: http://stackoverflow.com/questions/3021476/problem-with-hide-show-in-jquery thanks:) Now i added another fancy thing - jquery tabs Made a few modifications and it works like this: When you click on tab and it loads different main image for every tab. The problem is that i used $(document).ready(function() to handle those image changes. When i click any of 2x2 box images (on any tab) it will permanently change the image on the right and when i click on tabs it won't work like it did at the beginning. online example: http://rarelips.ayz.pl/testy/2/ code: <style type="text/css"> body { font: Arial, Helvetica, sans-serif normal 10px;

Modifying a HTML page to fix several "bugs" add a function to next/previous on a option dropdown

- by Dennis Sylvian

SOF, I've got a few problems plaguing me at the moment and am wondering if anyone could assist me with them. I'm trying to get Next Class | Previous Class to act as buttons so that when Next Class is clicked it will go to the next item in the dropdown list and for previous it would go to back one. There used to be a scroll bar that allowed me to scroll the main window left and right, it's missing because (I think it was to do with the scroll left and scroll right function) The footer at the bottom doesn't show correctly on mobile devices; for some reason it appears completely differently to as it does on a computer. The "bar" practically and the Scroll Left and Scroll buttons don't appear at all on mobile devices. The scroll left button is unable to be clicked for some reason, I'm unsure what I've done wrong. Refreshing the page resets the horizontal scroll position to far left (I'm pretty sure this relates to the scroll bar) I want to also find a way so that on mobile devices the the header will not show the placeholder image, however I can't work out what CSS media tag(s) I should be using.

Having an issue with overwriting an element of a file correctly (numeric)

- by IngeniousHax

This is an ATM style program, but currently it doesn't do exactly what I need it to do... I need to get the current balance, and when money is transferred from either checking or savings, it should add it to checking and subtract it from savings. which is does, but not correctly... Input example -=[ Funds Transfer ]=- -=[ Savings to Checking ]=- Account Name: nomadic Amount to transfer: $400 New Balance in Checking: $900 // original was 500 New Balance in Savings: $7.7068e+012 // this should now be 1100... Here is my code, it's a lot of code, but there are no errors, so throwing it into an IDE and compiling should be fairly quick for whoever would like to help. mainBankClass.h mainBankClass.h #ifndef MAINBANKCLASS_H #define MAINBANKCLASS_H #include <iostream> #include <fstream> #include <string> using namespace std; class Banking { protected: string checkAcctName, saveAcctName; // Name on the account int acctNumber[13]; // Account number float acctBalance, initSaveDeposit, initCheckDeposit, depAmt; // amount in account, and amount to deposit public: char getBalanceChoice(); // Get name on account for displaying relevant information char newAccountMenu(); // Create a new account and assign it a random account number void invalid(char *); // If an invalid option is chosen char menu(); // Print the main menu for the user. virtual float deposit(){ return 0; } // virtual function for deposits // virtual float withdrawal() = 0; // Virtual function for withdrawals void fatal(char *); // Handles fatal errors.

Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core. Made for an easy cut-and-paste operation with a few items being switched from one to another. Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview? Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar. The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM. We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase. This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this. Then you can add-on functionality as needed. Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03. private int _applicantID; 04. public int ApplicantID 05. { 06. get { return this._applicantID; } 07. set 08. { 09. if (_applicantID != value) 10. { 11. _applicantID = value; 12. OnPropertyChanged("ApplicantID"); 13. } 14. } 15. } 16. 17. private int _postingID; 18. public int PostingID 19. { 20. get { return _postingID; } 21. set 22. { 23. if (_postingID != value) 24. { 25. _postingID = value; 26. OnPropertyChanged("PostingID"); 27. } 28. } 29. } 30. 31. private string _body; 32. public string Body 33. { 34. get { return _body; } 35. set 36. { 37. if (_body != value) 38. { 39. _body = value; 40. OnPropertyChanged("Body"); 41. } 42. } 43. } 44. 45. private int _interviewID; 46. public int InterviewID 47. { 48. get { return _interviewID; } 49. set 50. { 51. if (_interviewID != value) 52. { 53. _interviewID = value; 54. OnPropertyChanged("InterviewID"); 55. } 56. } 57. } 58. 59. public override IAppointment Copy() 60. { 61. IAppointment appointment = new InterviewAppointment(); 62. appointment.CopyFrom(this); 63. return appointment; 64. } 65. 66. public override void CopyFrom(IAppointment other) 67. { 68. base.CopyFrom(other); 69. var appointment = other as InterviewAppointment; 70. if (appointment != null) 71. { 72. ApplicantID = appointment.ApplicantID; 73. PostingID = appointment.PostingID; 74. Body = appointment.Body; 75. InterviewID = appointment.InterviewID; 76. } 77. } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc. But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is. The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased. For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control. I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog. Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.  003. <helpers:DataContextProxy x:Key="DataContextProxy" /> 004. 005. <telerik:Windows7Theme x:Key="Theme" /> 006. <SolidColorBrush x:Key="DialogWindowBackground" 007.

Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting. The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection. You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02. Grid.Row="1" 03. Grid.Column="1" 04. Width="800" 05. MinWidth="600" 06. Height="500" 07. MinHeight="300" 08. AppointmentsSource="{Binding Interviews}" 09.

And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events. This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.

I know this is something which will be fixed down the line for using RadScheduler, simplifying this process, but with WCF RIA changing as it does I wanted to ensure functionality would remain consistent as I continued development on this application. So, I do a little bit of duplication, but for the greater good. This all takes place starting on line 79, so for every entity that comes back we add it to the collection that is bound to RadScheduler. Otherwise, the DelegateCommands that you see correspond directly to the events they are named after. In each case, rather than sending over the full event arguments, I just send in the appointment in question (coming through as the object obj in all cases) so I can add (line 91), edit (line 119), and delete appointments (line 142) like normal. This just ensures they get updated back to my database. Also, the one bit of code you won't see is for the Appointment Creating (line 110) event- that is because in the command I've created I simply make the replacement I need to: 1.void element_AppointmentCreating(object sender, AppointmentCreatingEventArgs e) 2.{ 3. e.NewAppointment = new InterviewAppointment(); 4. base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments. End result? I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm. I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version. For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02. Grid.Row="1" 03. Grid.Column="1" 04. Width="800" 05. MinWidth="600" 06. Height="500" 07. MinHeight="300" 08. EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09. AppointmentAdded="xJobsScheduler_AppointmentAdded" 10. AppointmentCreating="xJobsScheduler_AppointmentCreating" 11. AppointmentEdited="xJobsScheduler_AppointmentEdited" 12. AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right? Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate. The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event. Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003. public RecruitingContext context; 004. 005. private QueryableCollectionView _jobsList; 006. public QueryableCollectionView JobsList 007. { 008. get { return this._jobsList; } 009. set 010. { 011. if (this._jobsList != value) 012. { 013. this._jobsList = value; 014. this.NotifyChanged("JobsList"); 015. } 016. } 017. } 018. 019. private QueryableCollectionView _applicantList; 020. public QueryableCollectionView ApplicantList 021. { 022. get { return _applicantList; } 023. set 024. { 025. if (_applicantList != value) 026. { 027. _applicantList = value; 028.

See on line 51 where I set the DataContext before the Loaded event? This is super important, as if you don't have this set before the usercontrol is loaded, the DataContextProxy has no context to use and your EditAppointmentDialog Job/Applicant dropdowns will be blank and empty. Trust me on this, took a little bit of debugging to figure out that by setting the DataContext post-loaded would only lead to disaster and frustration. Otherwise, the only other real difference is that instead of sending an ActionHistory item through an event to get added to the database and saved, I do those right in the callback from submitting. The Result Again, I only have to post one picture because these bad boys used nearly identical code for both the MVVM and the code-behind views, so our end result is... So what have we learned here today? One, for the most part this MVVM thing is somewhat easy. Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow. Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4. Brilliant! MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development. Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view. Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Silverlight Recruiting Application Part 6 - Adding an Interview Scheduling Module/View

Between the last post and this one I went ahead and carried the ideas for the Jobs module and view into the Applicants module and view- they're both doing more or less the same thing, except with different objects being at their core. Made for an easy cut-and-paste operation with a few items being switched from one to another. Now that we have the ability to add postings and applicants, wouldn't it be nice if we could schedule an interview? Of course it would! Scheduling Module I think you get the drift from previous posts that these project structures start looking somewhat similar. The interview scheduling module is no different than the rest- it gets a SchedulingModule.cs file at the root that inherits from IModule, and there is a single SchedulerView.xsml and SchedulerViewModel.cs setup for our V+VM. We have one unique concern as we enter into this- RadScheduler deals with AppointmentsSource, not ItemsSource, so there are some special considerations to take into account when planning this module. First, I need something which inherits from AppointmentBase. This is the core of the RadScheduler appointment, and if you are planning to do any form of custom appointment, you'll want it to inherit from this. Then you can add-on functionality as needed. Here is my addition to the mix, the InterviewAppointment: 01.public class InterviewAppointment : AppointmentBase 02.{ 03. private int _applicantID; 04. public int ApplicantID 05. { 06. get { return this._applicantID; } 07. set 08. { 09. if (_applicantID != value) 10. { 11. _applicantID = value; 12. OnPropertyChanged("ApplicantID"); 13. } 14. } 15. } 16. 17. private int _postingID; 18. public int PostingID 19. { 20. get { return _postingID; } 21. set 22. { 23. if (_postingID != value) 24. { 25. _postingID = value; 26. OnPropertyChanged("PostingID"); 27. } 28. } 29. } 30. 31. private string _body; 32. public string Body 33. { 34. get { return _body; } 35. set 36. { 37. if (_body != value) 38. { 39. _body = value; 40. OnPropertyChanged("Body"); 41. } 42. } 43. } 44. 45. private int _interviewID; 46. public int InterviewID 47. { 48. get { return _interviewID; } 49. set 50. { 51. if (_interviewID != value) 52. { 53. _interviewID = value; 54. OnPropertyChanged("InterviewID"); 55. } 56. } 57. } 58. 59. public override IAppointment Copy() 60. { 61. IAppointment appointment = new InterviewAppointment(); 62. appointment.CopyFrom(this); 63. return appointment; 64. } 65. 66. public override void CopyFrom(IAppointment other) 67. { 68. base.CopyFrom(other); 69. var appointment = other as InterviewAppointment; 70. if (appointment != null) 71. { 72. ApplicantID = appointment.ApplicantID; 73. PostingID = appointment.PostingID; 74. Body = appointment.Body; 75. InterviewID = appointment.InterviewID; 76. } 77. } 78.} Nothing too exciting going on here, we just make sure that our custom fields are persisted (specifically set in CopyFrom at the bottom) and notifications are fired- otherwise this ends up exactly like the standard appointment as far as interactions, etc. But if we've got custom appointment items... that also means we need to customize what our appointment dialog window will look like. Customizing the Edit Appointment Dialog This initially sounds a lot more intimidating than it really is. The first step here depends on what you're dealing with for theming, but for ease of everything I went ahead and extracted my templates in Blend for RadScheduler so I could modify it as I pleased. For the faint of heart, the RadScheduler template is a few thousand lines of goodness since there are some very complex things going on in that control. I've gone ahead and trimmed down the template parts I don't need as much as possible, so what is left is all that is relevant to the Edit Appointment Dialog. Here's the resulting Xaml, with line numbers, so I can explain further: 001.<UserControl.Resources> 002.  003. <helpers:DataContextProxy x:Key="DataContextProxy" /> 004. 005. <telerik:Windows7Theme x:Key="Theme" /> 006. <SolidColorBrush x:Key="DialogWindowBackground" 007.

Where we start getting into the dialog in question is line 132, but line 407 is where things start getting interesting. The ItemsSource is pointing at a list that exists in my ViewModel (or code-behind, if it is used as a DataContext), the SelectedValue is the item I am actually binding from the applicant (note the TwoWay binding), and SelectedValuePath and DisplayMemberPath ensure the proper applicant is being displayed from the collection. You will also see similar starting on line 420 where I do the same for the Jobs we'll be displaying. Just to wrap-up the Xaml, here's the RadScheduler declaraction that ties this all together and will be the main focus of our view: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02.

And for those of you who remember the jobs post, those command:s in the Xaml are pointing to attached behavior commands that reproduce the respective events. This becomes very handy when we're setting up the code-behind version. ;) ViewModel I've been liking this approach so far, so I'm going to put the entire ViewModel here and then go into the lines of interest.

I know this is something which will be fixed down the line for using RadScheduler, simplifying this process, but with WCF RIA changing as it does I wanted to ensure functionality would remain consistent as I continued development on this application. So, I do a little bit of duplication, but for the greater good. This all takes place starting on line 79, so for every entity that comes back we add it to the collection that is bound to RadScheduler. Otherwise, the DelegateCommands that you see correspond directly to the events they are named after. In each case, rather than sending over the full event arguments, I just send in the appointment in question (coming through as the object obj in all cases) so I can add (line 91), edit (line 119), and delete appointments (line 142) like normal. This just ensures they get updated back to my database. Also, the one bit of code you won't see is for the Appointment Creating (line 110) event- that is because in the command I've created I simply make the replacement I need to: 1.void element_AppointmentCreating(object sender, AppointmentCreatingEventArgs e) 2.{ 3. e.NewAppointment = new InterviewAppointment(); 4. base.ExecuteCommand(); 5.} And the ViewModel is none the wiser, the appointments just work as far as it is concerned since as they are created they become InterviewAppointments. End result? I've customized my EditAppointmentDialog as follows: And adding, editing, and deleting appointments works like a charm. I can even 'edit' by moving appointments around RadScheduler, so as they are dropped into a timeslot they perform their full edit routine and things get updated. And then, the Code-Behind Version Perhaps the thing I like the most about doing one then the other is I get to steal 90% or more of the code from the MVVM version. For example, the only real changes to the Code-Behind Xaml file exist in the control declaration, in which I use events instead of attached-behavior-event-commands: 01.<telerikScheduler:RadScheduler x:Name="xJobsScheduler" 02. Grid.Row="1" 03. Grid.Column="1" 04. Width="800" 05. MinWidth="600" 06. Height="500" 07. MinHeight="300" 08. EditAppointmentStyle="{StaticResource EditAppointmentStyle}" 09. AppointmentAdded="xJobsScheduler_AppointmentAdded" 10. AppointmentCreating="xJobsScheduler_AppointmentCreating" 11. AppointmentEdited="xJobsScheduler_AppointmentEdited" 12. AppointmentDeleted="xJobsScheduler_AppointmentDeleted"> 13.</telerikScheduler:RadScheduler> Easy, right? Otherwise, all the same styling in UserControl.Resources was re-used, right down to the DataContextProxy that lets us bind to a collection from our viewmodel (in this case, our code-behind) to use within the DataTemplate. The code conversion gets even easier, as I could literally copy and paste almost everything from the ViewModel to my Code-Behind, just a matter of pasting the right section into the right event. Here's the code-behind as proof: 001.public partial class SchedulingView : UserControl, INotifyPropertyChanged 002.{ 003. public RecruitingContext context; 004. 005. private QueryableCollectionView _jobsList; 006. public QueryableCollectionView JobsList 007. { 008. get { return this._jobsList; } 009. set 010. { 011. if (this._jobsList != value) 012. { 013. this._jobsList = value; 014. this.NotifyChanged("JobsList"); 015. } 016. } 017. } 018. 019. private QueryableCollectionView _applicantList; 020. public QueryableCollectionView ApplicantList 021. { 022. get { return _applicantList; } 023. set 024. { 025. if (_applicantList != value) 026. { 027. _applicantList = value; 028.

See on line 51 where I set the DataContext before the Loaded event? This is super important, as if you don't have this set before the usercontrol is loaded, the DataContextProxy has no context to use and your EditAppointmentDialog Job/Applicant dropdowns will be blank and empty. Trust me on this, took a little bit of debugging to figure out that by setting the DataContext post-loaded would only lead to disaster and frustration. Otherwise, the only other real difference is that instead of sending an ActionHistory item through an event to get added to the database and saved, I do those right in the callback from submitting. The Result Again, I only have to post one picture because these bad boys used nearly identical code for both the MVVM and the code-behind views, so our end result is... So what have we learned here today? One, for the most part this MVVM thing is somewhat easy. Yeah, you sometimes have to write a bunch of extra code, but with the help of a few useful snippits you can turn the process into a pretty streamlined little workflow. Heck, this story gets even easier as you can see in this blog post by Michael Washington- specifically run a find on 'InvokeCommandAction' and you'll see the section regarding the command on TreeView in Blend 4. Brilliant! MVVM never looked so sweet! Otherwise, it is business as usual with RadScheduler for Silverlight whichever path you're choosing for your development. Between now and the next post, I'll be cleaning up styles a bit (those RadComboBoxes are a little too close to my labels!) and adding some to the RowDetailsViews for Applicants and Jobs, so you can see all the info for an appointment in the dropdown tab view. Otherwise, we're about ready to call a wrap on this oneDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.
