Forgot
For my class library I had these reference errors
Error 1 Project file must include the .NET Framework assembly
'WindowsBase, PresentationCore, PresentationFramework' in the reference
list. PathWestImages.
After I added these to my class library it was happy (at least I was
anyway).
Its nice to get an error that was actually meaningful. I have any number
of 'unknown error' which leaves one scratching one's head.

Hi Peter,
What you have done should work.
Check that the Build Option of the image files in the assembly is set to
Resource (not Embedded Resource/Content/None). Also double check that
the file name is capitalized correctly. If it's in a folder, you'll need
to include that too:
/PathWestImages;component/My/Path/To/File.jpg
You shouldn't need to set the bin\Debug path -- adding the reference
from your main project (and making sure Copy Local = true in the project
properties) should ensure it gets copied there.

*Subject:* WPF Images in a resource
I am learning WPF so I am very much a newbie. I want to be able to
reference images with an Image control from within an assembly.
Something similar to the Resources available to WinForms development.
According to
http://social.msdn.microsoft.com/forums/en-US/wpf/thread/16bce8a4-1ee7-4be9-bd7f-0cc2b0f80cf0/
You
1. Create a control library and include the image files asResources
2. In your app, add a reference to the library above
3. Access the image files via "/<libraryName>;component/<path to
image>" type of relative Uris. For e.g. if your control library is
ImageStore.dll, then to refer to foo.png, you'd have
"/ImageStore;component/foo.png"
In XAML, this can be <Image Source="/ImageStore;component/foo.png" />
I am not sure what a 'control' library is. I assumed that this was a
'class' library (which may be incorrect). I created one called
PathWestImages and added a resources file to it and deleted the class
added by default. I set it to build to the bin/debug directory of my WPF
application. I added a jpg file to my resources class and did a build. I
then added a reference to the class library in my WPF application.
In my XAML I tried
<Image Grid.ColumnSpan="3" Grid.Row="0" Grid.Column="0" HorizontalAlignment="Stretch" Stretch="Fill" VerticalAlignment="Stretch"
MinHeight="50" Source="/PathWestImages;component/banner.jpg">
But it says it cannot locate banner.jpg.
I did some googling and just found
http://windowsclient.net/blogs/nidonocu/archive/2008/02/16/wpf-themes-and-control-libraries.aspx
so I am fairly sure my preconceptions were invalid. I have not had time
to read this fully as I have to go out for a while. I'll try and digest
it when I get back.
Is there an easy way to do this? Any simple pointers to follow.
I thought that while WPF was different to WinForms, being such a
graphically rich development environment this sort of thing would be
easier than WinForms not harder.
Regards Peter
