[news.eclipse.platform.swt] Re: OLE Sample and 2.1 Changes

["Veronika Irvine" <veronika_irvine@xxxxxxx>]

In the past, if you had a Variant of type VT_EMPTY and asked for the int
value, it returned 0.  In 2.1 it throws an exception.

You can use Variant.getType to check for VT_EMPTY and avoid the exception.
