The last error code from an HTTP operation. Same as the value return by HttpGetEx typically.

The error codes come either from WinInet (12000-13000 range) or from the Windows API (anything below that generally 0 - 255). Most errors will also set the cErrorMsg property which you should check for further info. However some errors do not. The following URL provides more info on WinInet error codes that might not be 'parsed':
