Eclipse plugin: How to find from which View the user opened a Dialog?
I know how to find out whether a View like the "Project Explorer" is open in Eclipse. But how can I determine if the user opened a dialog from the "z/OS Projects" View or from the "Project Explorer" View?
On base of the result, I need to locate a file in the current active View.
This part I got covered already.

I don't think you can. It is normal to use use the current selection rather than trying to find a view. This is straightforward in a handler.

Thanks Greg, can you follow up on this by giving an example? :-)

Not until you give more information. Is this a dialog you are opening from and command handler (something extending AbstractHandler)? If not what are you doing?

Sure. I am opening a LocateMemberHandler: public class LocateMemberHandler extends AbstractHandler{ It is used to quickly locate files accross the workbench. A Locate button on the dialog will locate the selected file in z/OS Projects or Project Explorer (expanding all folders) without opening the source code.

In a handler class extending AbstractHandler you can use the HandlerUtil method to get various information from the execution event.
For the current selection you can use:
IStructuredSelection sel = HandlerUtil.getCurrentStructuredSelection(event);
where event is the ExecutionEvent passed to the handler.
To get any resource (such as an IFile) contained in the selection use:
IResource resource = Adapters.adapt(sel.getFirstElement(), IResource.class);
(you may also be able to adapt directly to IFile).
Note: both getCurrentStructuredSelection and Adapters are only in fairly recent versions of Eclipse. For older versions the code is a little more complex.
