Here is a brute force solution to the fetch puzzle. Basically, at each step there are three possibilities :

1. You can fill a bucket.
2. You can transfer water from one bucket to the other one.
3. You can dump out the water from a bucket.

In this brute force solution, I try each one of these steps and then try all three again after each one of the previous steps. And on and on until I get the required amount of water in one of the buckets.

Check it out. Source code is on my github repo - https://github.com/ashtewari/fetch

I have completed developing this app and I would like to get it in the hands of a few more people to get some additional feedback before I submit it in windows phone marketplace. If you have a windows phone and a windows live id, you can help with this. Your phone does not need to be a developer (unlocked) phone.

If you are interested, contact me.

Here is what I will do for you :

Positioned ChildWindow

Here is a live demo : childwindow-positioning-demo

And here is the code :

public partial class ChildWindowEx : ChildWindow
{
	
    Point _pt = new Point(0,0);
	
    public ChildWindowEx()
    {
        InitializeComponent();
    }
	
    public ChildWindowEx(Point pt) : this()
    {
        _pt = pt;
    }
	
    protected override Size ArrangeOverride(Size finalSize)
    {
        Grid grid = Utils.FindChild(this, \"ContentRoot\");
	
        if (grid != null)
        {
            grid.Arrange(new Rect(_pt.X, _pt.Y, grid.DesiredSize.Width, grid.DesiredSize.Height));
            return finalSize;
        }
	
        return base.ArrangeOverride(finalSize);
    }
}

I need to display a list of items that are not highlighted when selected. This is a common scenario when displaying an inactive list for simply listing out some information.

ListBoxItem’s default template can be easily inspected and modified using Expression Blend – Select a ListBoxItem in Objects and Timeline pane, Right click and select Edit template > Edit a Copy. Name you template and save it at the scope of your choice.

This will create a copy of the template and allow you to modify it. Switch to the xaml view. Locate the VisualStates of MouseOver, Selected and Focused, and blank them out -

The style is applied to the ListBoxItems using ItemContainerStyle -

Here is the xaml style for the ListBoxItem -
<Style x:Key="ListBoxtemStyleNoHighlighting" TargetType="ListBoxItem"><br /> <Setter Property="Padding" Value="3"/><br /> <Setter Property="HorizontalContentAlignment" Value="Left"/><br /> <Setter Property="VerticalContentAlignment" Value="Top"/><br /> <Setter Property="Background" Value="Transparent"/><br /> <Setter Property="BorderThickness" Value="1"/><br /> <Setter Property="TabNavigation" Value="Local"/><br /> <Setter Property="Template"><br /> <Setter.Value><br /> <ControlTemplate TargetType="ListBoxItem"><br /> <Grid Background="{TemplateBinding Background}"><br /> <VisualStateManager.VisualStateGroups><br /> <VisualStateGroup x:Name="CommonStates"><br /> <VisualState x:Name="Normal"/><br /> <VisualState x:Name="MouseOver"/><br /> </VisualStateGroup><br /> <VisualStateGroup x:Name="SelectionStates"><br /> <VisualState x:Name="Unselected"/><br /> <VisualState x:Name="Selected"/><br /> </VisualStateGroup><br /> <VisualStateGroup x:Name="FocusStates"><br /> <VisualState x:Name="Focused"/><br /> <VisualState x:Name="Unfocused"/><br /> </VisualStateGroup><br /> </VisualStateManager.VisualStateGroups><br /> <Rectangle x:Name="fillColor" Fill="#FFBADDE9" IsHitTestVisible="False"<br /> Opacity="0" RadiusY="1" RadiusX="1"/><br /> <Rectangle x:Name="fillColor2" Fill="#FFBADDE9" IsHitTestVisible="False"<br /> Opacity="0" RadiusY="1" RadiusX="1"/><br /> <ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}"<br /> Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"<br /> Margin="{TemplateBinding Padding}"/><br /> <Rectangle x:Name="FocusVisualElement" RadiusY="1" RadiusX="1" Stroke="#FF6DBDD1"<br /> StrokeThickness="1" Visibility="Collapsed"/><br /> </Grid><br /> </ControlTemplate><br /> </Setter.Value><br /> </Setter><br /> </Style>

After the style is applied, the ListBoxItems are not highlighted when selected or focused. Here is a live demo of a ListBox that does not highlight when items are selected : remove-listboxitem-hlighting-demo

2. Unlock your phone – using PhoneReg.exe (usually) located here – “C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.0\Tools\Phone Registration\PhoneReg.exe”

3. Sideload xap into your phone. Use XapDeploy.exe (usually) located here – “C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.0\Tools\XAP Deployment\XapDeploy.exe”

You can also deploy straight from Visual Studio to Windows Phone Device. Connect your phone to your computer.
Make sure Visual Studio deployment target is “Windows Phone 7 Device” :

I will dissect a Sample WPF MVVM application and then highlight the most important aspects of the MVVM by coding a brand new ViewModel and incorporating it into the application. You will learn about the Roles of the MVVM triad, the advantages of using MVVM and Characteristics of the ViewModel.

Attendees will be eligible to win two copies one copy (see below) of Josh Smith’s Advanced MVVM book as well as a few other WPF Books.

{ I will be giving away one hard copy version of the book instead of digital versions due to concerns about DRM protection and unclear gift guidelines at lulu.com }.

And the winner is … Mark Freeman !!! Congratulations Mark, your copy of “Advanced MVVM” is on its way. Thanks for attending the code camp and your feedback.

Which changesets do you select to merge ? 56-60, right ? Well, not exactly. It depends. If you are using Subversion merge command, you will need to specify 55-60. If you are using TortoiseSVN, you will select 56-60. You should keep this in mind if you are used to TortoiseSVN and you are attempting a merge using SVN merge command. Otherwise, you will end up with a merge without change 56.

Selecting changes to merge can become non-trivial when you don’t know which changes have already been merged. However, there is good news. With subversion 1.5, when you are selecting changes from source branch to merge into a target branch, don’t do it ! Subversion 1.5 onwards has built-in merge tracking. When using TortoiseSVN, if your intention is to merge all changes, just leave the changeset selection blank. Subversion knows which ones have already been merged and which ones to merge and it does it automatically. You can also select changes that have already been merged and those will be handled (excluded) automatically too.

There is a summary of what to expect from Subversion Merge-Tracking feature here – Subversion 1.5 merge-tracking in a nutshell.

There is detailed description of Subversion Merge-Tracking here and search for ‘mergeinfo property’ in Subversion documentation.

The above screen-shot shows the changes already merged in grey. Thanks to Subversion’s mergeinfo property.

So, can I just stop worrying about changesets altogether, when merging ? There are a few caveats to how mergeinfo metadata is (and sometimes not) recorded. Read this for more information -  The Final Word on Merge Tracking.

Read about Subversion merging and branching here and TortoiseSVN merging documentation here – browse down to these sections : Reviewing the Merge Results and Merge Tracking.
