CONTROL PANEL

[Cyrus]

i have written a software that uses DATES and System Dates for calculation and printing formatted as dd/mm/yyyy which is being used for quites sometime, suddenly my programs starts giving wrong results on date calculation as well as in printing. I have discovered that one fkng happy trigger user changed the system date format to mm/dd/yyyy through control panel. Anybody have an idea to protect a software for such unknown changes in system settings.? Is there a way to limit the access of the control panel.?

thanks

...the regional settings is a service of windows... if U develop in windows U must consider this service.
For a correct reading of a date U can use function as dateserial,month,year,weekday...

'use the following code
'The declarations
