Where can I get codes for creating a trial version
workbook / self deleting or read about it to learn (I know
Excel VBA is not very secure and can be broken into.
However, vast majority would not know how). Thnks for your
help.

Common recommendation is to hide all your sheets except one that cautions
the user to enable macros. So if macros are enabled, then in the
Workbook_Open event, you would "set up" your workbook and in the
Workbook_BeforeClose Event, you would hide the sheets and save the workbook.

There is no standard code for this, but if you have developed an application
that uses VBA, then you should have no trouble designing your own.

You can search google groups for past posting on this topic and this group
and probably get some sample code.

Yes there is no standard way of doing this except locking stuff an
making a method of corupting the workbook after a certain time. I als
like to put a modeless form when they open the workbook that says Thi
is a Trial Version......... and some other stuff. It doesn't hinde
the program but it is just an anoyence incase they crack the count dow
method.
Just remember, if they know what they are doing and want into th
program, there is always a way........
