Set window icon correctly and happening XamlParseException - c#

I set window icon property in xaml code or in the properties window correctly in a very simple wpf application, but visual studio always throws an XamlParseException at runtime. Why is this happening?(using visual studio 2013 and windows 8, my icon size is 15 KB)
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Icon="pack://siteoforigin:,,,/Resources/MyIcon.ico">
<Grid>
</Grid> </Window>
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Icon="/Resources/MyIcon.ico">
<Grid>
</Grid> </Window>

It is a problem with your image Build Action Property, check the arrows for further info..

WPF - Resize window from user control on run time

My application works with main window and user controls for every view.
the main window have default size.
I want that one of the user controls will change its size when entering the view.
when i change the size with local it changes the user control and not the width and height of the window.
Main window :
<Window x:Class="EEPromTool2.View.MainMenu"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

WindowStyle="None"
ResizeMode="CanResizeWithGrip" AllowsTransparency="True"
mc:Ignorable="d"

User control :

Thanks for any advice.

Can't change DataContext WPF

I am trying to use a MVVM pattern instead of putting all logic in the code-behind file, but I can't seem to get it working.
My view is this:
<Window x:Class="WpfApp4.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApp4"
mc:Ignorable="d"
xmlns:vm="clr-namespace:WpfApp4.ViewModel"
Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
<vm:ViewModelMain />
</Window.DataContext>
<Grid>
</Grid>
And this is my ViewModel:
namespace WpfApp4.ViewModel
{
class ViewModelMain
{
}
}
What am I doing wrong here?
Visual studio can be a bit temperamental sometimes with xaml warnings and errors. Try closing the window, and/or cleaning and rebuilding the project, or if all else fails close all windows and restart visual studio

Get XAML code in WPF

How can I get XAML code of a window as a string, change this string, and upload this string as a xaml-code of window?
For example, I have
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ComboBox Margin="0,0,9,38" Name="button1" Height="82" HorizontalAlignment="Right" VerticalAlignment="Bottom" Width="132"></ComboBox>
</Grid>
</Window>
and I want to have this xaml code in the end
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ComboBox Margin="0,0,9,38" Name="button1" Height="82" HorizontalAlignment="Right" VerticalAlignment="Bottom" Width="132">
<ComboBox.ItemTemplate>
<DataTemplate>
<local:d_dddw_imp_insurance_list />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
</Grid>
</Window>
If your using wpf/xaml with c#, visual studio generally compile the xaml code to c#, to be as performant as possible. If you want to have some dynamic XAML, you need to use XamlReader to read xaml and display at "on your own".
Just take a look at: Loading XAML XML through runtime
Than you can change or manipulate the xaml and display the result very easily.

WPF - Update static resource value at runtime

I have code similar to the following:
<Application
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Software_Suite_Maker"
xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" x:Class="WpfApplication1.App"
StartupUri="MainWindow.xaml">
<Application.Resources>
<FontFamily x:Key="FontFamilyName">./Fonts/#Segoe UI</FontFamily>
</Application.Resources>
and the Window xaml code is:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<TextBox FontFamily="{StaticResource FontFamilyName}" Margin="135,122,187,180" Text="test"/>
<Button FontFamily="{StaticResource FontFamilyName}" Margin="135,144,329,154" Content="test"/>
</Grid>
Now I want to change the value of FontFamilyName from behind code. I wrote this code:
var font = TryFindResource("FontFamilyName") as FontFamily;
font = new FontFamily("./Fonts/#Tahoma");
But nothing happened and did not change.
My question is: How can I change FontFamilyName value from behind code and changes will also be made on the objects?
You have to use a DynamicResource for that :
<TextBox FontFamily="{DynamicResource FontFamilyName}" Margin="135,122,187,180"
Text="test"/>
<Button FontFamily="{DynamicResource FontFamilyName}" Margin="135,144,329,154"
Content="test"/>
Read on MSDN about DynamicResource:
Provides a value for any XAML property attribute by deferring that value to be a reference to a defined resource. Lookup behavior for that resource is analogous to run-time lookup.

Looking to find how to add resize button

Hello:
I have been experimenting with WPF this afternoon, Im wondering does anyone know how I can manually enable resizing ? I have my main windows set with the following properties which removes the close/min/max and resize;
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" AllowsTransparency="True"
WindowStyle="None" Background="Maroon" ResizeMode="CanResize">
</Window>
I have found how to add my own close/min/max buttons but have not found how to enable resizing.
ResizeMode="CanResizeWithGrip"
