    "Html": "<p>The problem is with the using statement, but the solution is NOT to remove the using statement.&nbsp;</p>\r\n<p>The problem is you have called zipfile.Save(), which happens in your CreateZipFile() method, &nbsp;before attaching the progress event to the zipfile object, which happens later in the CoverArchive() method.&nbsp;</p>\r\n<p>I'd suggest refactoring your code to put the using() statement outside all references to the zipfile object. &nbsp;Do not remove the using() statement; that will result in other problems.&nbsp;</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>",
