Method and computer-readable medium for verifying and saving an electronic document

A computer-readable medium having computer-executable instructions stored thereon which, when executed by a computer, will cause the computer to:

• provide a first saving mode for saving the contents of a memory structure having one or more portions from a volatile memory to a data file on a mass storage device, wherein minimal integrity checking is performed on each of the portions when saving in the first saving mode;
• provide a second saving mode for saving the contents of the memory structure to the data file, wherein more extensive integrity checking is performed on each of the portions and wherein saving of each unsaveable portion is skipped;
• begin saving the contents of the memory structure in the first saving mode;
• and to
• determine when operating in the first saving mode whether a portion of the memory structure is unsaveable and in response to determining that a portion is unsaveable, switching to the second saving mode.

A computer-readable medium having computer-executable instructions stored thereon which, when executed by a computer, will cause the computer to:

• provide a first saving mode, a second saving mode, and a third saving mode;
• begin saving the contents of a memory structure having one or more data records in the first saving mode, wherein minimal integrity checking is performed on the data records;
• determine while saving the data file in the first saving mode whether one of the data records is missing or corrupt;
• in response to determining in the first saving mode that one of the data records is unsaveable, switching to the second saving mode;
• attempt to save the contents of the memory structure from its beginning in the second saving mode, wherein in the second saving mode additional integrity checks are performed on the data records as compared to the first mode and wherein the saving of any unsaveable records is skipped;
• determine while saving the data file in the second saving mode whether the saving of one of the data records cannot be skipped;
• and
• in response to determining that the saving of one of the data records cannot be skipped while saving in the second saving mode, switching to the third saving mode wherein only user data stored in the memory structure is saved.

A method for saving the contents of a memory structure comprising one or more records to a data file located on a mass storage device, the method comprising:

• providing a first saving mode, a second saving mode, and a third saving mode;
• attempting to save the contents of the memory structure to the data file in the first saving mode, wherein minimal integrity checking is performed on the data records while saving in the first saving mode;
• determining while saving the memory structure in the first saving mode whether one of the data records is unsaveable;
• in response to determining in the first saving mode that one of the data records is unsaveable, switching to the second saving mode;
• attempting to save the memory structure from its beginning in the second saving mode, wherein in the second saving mode additional integrity checks are performed on the data records as compared to the first mode and wherein the saving of any unsaveable records is skipped;
• determining while saving the memory structure in the second saving mode whether the saving of one of the data records cannot be skipped;
• and
• in response to determining that the saving of one of the data records cannot be skipped while saving in the second saving mode, switching to the third saving mode wherein only user data stored in the memory structure is saved.
