My Code is giving me a NaN value when I tried to test its return value. the code is here
C#:
var hx1 = Canvas.GetLeft(top);
var hy1 = Canvas.GetTop(top);
Rect h1 = new Rect(hx1, hy1, top.ActualWidth, top.ActualHeight);
Console.WriteLine(h1);
XAML
<Canvas Canvas.Left="134" Canvas.Top="98" Height="500" Width="1010">
<Ellipse Height="50" Name="top" Stroke="Black" Width="50" Margin="481,4,479,446" />
<Ellipse Height="50" Margin="30,21,930,429" Name="topLeft" Stroke="Black" Width="50" />
<Ellipse Height="50" Margin="30,430,930,20" Name="botLeft" Stroke="Black" Width="50" />
<Ellipse Height="50" Margin="481,444,479,6" Name="bot" Stroke="Black" Width="50" />
<Ellipse Height="50" Margin="930,430,30,20" Name="botRight" Stroke="Black" Width="50" />
<Ellipse Height="50" Margin="930,21,30,429" Name="topRight" Stroke="Black" Width="50" />
<Grid Canvas.Left="0" Canvas.Top="0" Height="500" Width="1010">
<!--<Canvas Height="500" Width="1010" Name="PoolCanvas">-->
<ContentControl x:Name="poolContainer">
</ContentControl>
<!--</Canvas>-->
</Grid>
</Canvas>
First of all, I am trying to make a pool game using WPF. Right now I am trying to make a 'pocket hole' for the ball to go in inside the pool. I was told about retrieving the holes x and y first or coordinates of the holes and later check the intersection and do the coding of balls putting it inside the pocket. However on my code, its only giving me this output:
NaN,NaN,50,50 when I tried to print that rect.
One more thing, If there is another type of method where I can fulfill these goals where if ball go inside the pocket hole. ball will disappear.
If you think I still need to give more code. Feel free to comment. I am open for suggestions. Thank you in advance and sorry if I have grammar errors.
Instead of using Ellipse to define each hole, you can use Path with EllipseGeometry:
<Canvas>
<Path Stroke="Black">
<Path.Data>
<EllipseGeometry x:Name="topLeft" Center="50,50" RadiusX="25" RadiusY="25"/>
</Path.Data>
</Path>
<Path Stroke="Black">
<Path.Data>
<EllipseGeometry x:Name="top" Center="500,50" RadiusX="25" RadiusY="25"/>
</Path.Data>
</Path>
<!-- More Paths, one for each hole -->
</Canvas>
Notice that now it's the geometries that are named, not the Paths themselves. So your C# code would be:
var hx1 = top.Center.X;
var hy1 = top.Center.Y;
var h1 = top.Center; // of type System.Windows.Point;
Rect h1rect = top.Bounds;
I have a canvas and I set a background image to it. I have some rectangles within the canvas. When the form gets resized, the background image gets strechted but I also want the rectangles to get to the new positions. Any help?

here is the background image set :

ib.ImageSource = new BitmapImage(new Uri(#"Media\foo.jpg", UriKind.Relative));
jasCanvas.Background = ib;
There is a very simple solution that you can use... just put your Canvas inside a ViewBox control. From the linked page on MSDN, the ViewBox Defines a content decorator that can stretch and scale a single child to fill the available space:
<ViewBox Stretch="Fill">
<jas:DragCanvas x:Name="jasCanvas">
...
</jas:DragCanvas>
</ViewBox>
If it doesn't work straight out of the box, then just experiment with the Stretch and StretchDirection properties.
I'm not sure about your jas namespace, but there is no layout system support in standard Canvas panel. So if you want something placed inside canvas to move and resize automatically due to parent canvas position change you have to create some code for this behavior manually.
Modify your XAML code like this:
<jas:DragCanvas x:Name="jasCanvas" SizeChanged="jasCanvas_SizeChanged">
And then in your code behind file:
private void Canvas_SizeChanged(object sender, SizeChangedEventArgs e)
{
var deltaWidth = (e.NewSize.Width - e.PreviousSize.Width);
m_redRect.Width += deltaWidth;
// and so on
}
I just found an icon set here:
http://www.archetype-inc.com/yard/fundamentals/icons/
I've been looking for something like it for a long time, however this doesn't give lots of PNG files, but rather an adobe illustrator and XAML file.
Luckily I'm using WPF, so hopefully I should be able to use the XAML file. Infact I preffer the idea to PNG due to that fact that it's scalable.
Anyway, my problem is I have no idea how to use it. I'm relatively new to XAML.
It's formatted with groups of canvases, for example, here is a bit from the start:

How would I put these icons into a regular WPF application? Is there any way?
Each control in WPF can be a container for others controls.. so it's really esay to in add a xaml image in a button. Copy a row of your iconset a put it into the button content.
<Button Width="30" Height="30">
<Button.Content>

For you 2nd question. It's possible to map each geometry in the resources with a different key, after you can add the icon simply by calling the its key.
<Window.Resources>
<StreamGeometry x:Key="Geometry1">F1M539.166,26.8541L539.853,26.8541 539.853,23.5416C539.869,22.4323 540.541,21.5885 541.635,21.5885 542.76,21.5885 543.072,22.3385 543.072,23.3073L543.072,26.8541 543.775,26.8541 543.775,23.1979C543.775,21.8541 543.291,21.0104 541.681,21.0104 540.885,21.0104 540.119,21.4791 539.869,22.151L539.853,22.151 539.853,21.1823 539.166,21.1823 539.166,26.8541z</StreamGeometry>

I have the following simple path. But everytime in Expression Blend I try and set a translate transform to its image brush the image disappears. Ideally the fill should be none. I need to dynamicly set the x and y of the image within the brush if possible. If you have done this in C# that would be fine as well. Or am I mistaken and this just cant be done?
<Path Data="M0.5,0.5 L99.5,0.5 L99.5,439.5 L0.5,439.5 z" Fill="#BFF31313" Height="440" Canvas.Left="192" Stretch="Fill" Stroke="Black" Canvas.Top="176" Width="100" Visibility="Collapsed">

<ImageBrush ImageSource="4x4.png" Stretch="None"/>
</Path.Fill>
</Path>
Something like this?
<Path Data="M0.5,0.5 L99.5,0.5 L99.5,439.5 L0.5,439.5 z" Fill="#BFF31313" Height="440" Canvas.Left="192" Stretch="Fill" Stroke="Black" Canvas.Top="176" Width="100" Visibility="Collapsed">

The tool you need is the TransformToVisual method which is provided by all UIElement derivatives including Path. To find the X,Y position of one of your paths relative to the containing Grid use:-
GeneralTransform gt = but77.TransformToVisual(LayoutRoot);
Point but77Position = gt.Transform(new Point(0,0));
