I need to have a flag like "DocumentChanged" and i should assign either "TRUE" or "FALSE" to it based on the document have been edited or not.

Regardless to whether the word document is saved or not, i would like to know whether any changes has been done to the document from the time when it got opened, even though the document got saved any number of times, if some changes happened then the flag which i have set should be marked correctly.

Also i don't want to use the Track Changes option to achieve this expected result. Thanks in advance.

Any kind of help is much appreciated.
