New ProvideEditorExtension for opening a PropertyPage

Hi,

I have added a Property Page to my VSIX, so that it is right now accessible from Project  Properties" via right button menu.

The data represented in this PropertyTab/Page is related to the project itself and it is also stored in other file with extension *.hmr. 

Now I want to doble click the myfile.hmr file and open directly my custom property tab/page that is shown inside my project's properties dialog. Is that possible?

I have added a new IVsEditorFactory class and I am able to catch the call after opening  myfile.hmr file but I don't know how to display my project properties at my custom tab from IVsEditorFactory.CreateEditorInstance method.

Thanks in advance...
