My.Resources in WPF XAML?

Question

Is there any way to access My.Resources through Xaml?

Like this

<Image Source="{Binding MyImage, Source={x:Static my:Resources}, Converter={StaticResource MyBitmapToImageSourceConverter}}" /> 

This is the error I get: \ Application.xaml (122.36): error MC3029: the member "my: Resources" is invalid because it does not have a qualification type name.

The above does not work of course.

NOTE. The converter is for illustration purposes only.

Update:

I was thinking of one idea that might be a good approach, if it works, I created a wrapper class for resources:

 Public Class Resources Public Shared ReadOnly m_Resources As New Resources Public Shared ReadOnly Property Resources() As Resources Get Return m_Resources End Get End Property Public ReadOnly Property MyResources(ByVal name As String) As Object Get Return My.Resources.ResourceManager.GetObject(name) End Get End Property End Class 

And then in my binding, I try to access it like this:

 <Setter Property="ImageSource" Value="{Binding MyResources[Ok], Source={x:Static src:Resources.Resources}}"/> 

But I still get the following message:

System.Windows.Data error: 16: Cannot get the value "MyResources" (enter "Object") from "(enter" Resources "). BindingExpression: Path = MyResources [Ok]; DataItem = 'Resources' (HashCode = 59109011) ; the target element is "Image" (Name = 'btnOk'); target is' Source '(type' ImageSource ') TargetParameterCountException:' System.Reflection.TargetParameterCountException: mismatch of the parameter counter.

By the way, I put a test MessageBox in MyResources Getter, and it seems that the properties are not available at all.

The problem is that, by default, the tool that generates the code for the Resource.resx file is VbMyResourcesResXFileCodeGenerator (the "Custom Tool" property of the project element). This tool generates a module in which the properties of the resource are internal (Friend), so StaticExtension cannot access it. To solve this problem, you should change the custom tool for Resource.resx to PublicVbMyResourcesResXFileCodeGenerator , which will generate open items.

In addition, the VB module is roughly equivalent to a static (Shared) class, so there is no instance of resources that can be used as a binding source, so you cannot specify Path to bind to. You must set the binding source directly to the desired property:

 <Image Source="{Binding Source={x:Static my:Resources.MyImage}, Converter={StaticResource MyBitmapToImageSourceConverter}}" /> 

Note. There is another pair of tools for generating code for the resource file: ResXFileCodeGenerator and PublicResXFileCodeGenerator . These tools generate a class instead of a module.

EDIT: The namespace mapping used is as follows:

 xmlns:myRes="clr-namespace:YourApplicationName.My.Resources"

Change the access modifier my.resources from friend to public on the resource tab my.project.
