Images not loading in windowbase from external DLL

Question

Hey there,

I've got a question regarding loading in images from a dll in a custom made window.

I started out making a WPF Content Control Library project (MyRes), where I made my own windowclass (MyWindow), to which I apply a style.

public class MyWindow : Window
    {
        public MyWindow()
        {
            this.Loaded += WindowLoaded;
            DefaultStyleKeyProperty.OverrideMetadata(typeof(MyWindow), new FrameworkPropertyMetadata(typeof(MyWindow)));
        }
    }

The general layout of the Themes\Generic.xaml is as following:

                              
<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:MyRes">

    <BitmapImage x:Key="leftImage" UriSource="/MyRes;component/Resources/Images/img1.bmp" />
    
    <BitmapImage x:Key="bgImage" UriSource="/MyRes;component/Resources/Images/img2.tiff" />

    <BitmapImage x:Key="rightImage" UriSource="/MyRes;component/Resources/Images/img3.jpg" />

<Style TargetType="{x:Type local:MyWindow"}>
  ... //Bunch of setters
  <!-- Set the template -->
  <Setter Property="Template">
      <Setter.Value>
           <ControlTemplate TargetType="{x:Type local:MyWindow}">
             <Grid>
               <Grid.Background>
                 <ImageBrush ImageSource="{StaticResource bgImage}"/>
               </Grid.Background>
               ... //row and col defs
               <Image Grid.Column="0" Grid.Row="0" Source="{StaticResource leftImage}" ..other properties. />
               ... //more images and buttons and statusbars etc
               <AdornerDecorator>
                   <ContentPresenter Content="{TemplateBinding Content}" Grid.Column="1" Grid.Row="1" Grid.ColumnSpan="3" Margin="{TemplateBinding Margin}" />
               </AdornerDecorator>

If I initialise this window in a new project, after referencing the DLL that comes out, like this:

<bwr:MyWindow x:Class="TestProject.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:bwr="clr-namespace:MyRes;assembly=MyRes"
        Title="MainWindow">
    <Grid>
        
    </Grid>
</bwr:MyWindow>

All the properties and layouts are applied to the window, but both of the images are not loaded correctly.

I tried both relative and absolute URI's, setting the image as 'content', 'resource' and 'embedded resource', but I can't find out why it won't load correctly.

Any help would be greatly appreciated.

Thanks in advance,

Shane

Hi Shane,

Please refer to the WPF Pack Uri in this link: http://msdn.microsoft.com/en-us/library/aa970069.aspx

Try "pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml" absolute pack Uri in the referenced assembly.

Have a nice day,
