How to auto protect area in mathcad 15

[adnn]

Dear all,

I have observed that once a user unlocks an area which was locked (password protected), and saves the file, the lock status gets changed immediately for ever. 

Is there any way I can do something like 

--------------- when mathcad sheet is opened, Areas (Area1, Area2, Area3 gets minimised and locked with password "xx123xx")--------------  The ultimate best option would also include that if any Area is unlocked and opened, upon closing, it automatically gets locked again (same password).

Excel VBA has something similar like Private Sub workbook_open()... Is there it's equivalent in Mathcad ? 

Your help is much appreciated !

Warm Regards,

Aravind

Whether an area is locked or unlocked is a state that is saved with the sheet.

If you need (part of) your sheet protected by a locked area, you need to make sure that you save the mathcad sheet in that locked state.

Success!
