Answer 1

The piece of code from the previous answer will work. However, keep in mind you can only open your dialog from the UI thread. If you are opening the dialog from a different thread, e.g. a background process, you need to do something like this:

PlatformUI.getWorkbench().getDisplay().asyncExec(new Runnable() {
    public void run() {
        Shell activeShell = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell();
    }
});

Otherwise you will get an exception when creating the dialog.
