How can i expire an exe

[king_saqib]

Hi how can expire an exe for example after using ane day it will expire

[debasisdas]

The simplest thing to do is to check system date on start up.

suppose you want for 30 days from today ---say 25_sep-2011.

in the start up check if the date is less than the above date.

if it is more display an error message.

for a better and full proof solution you need to write into system registry.

can you tell me the cde please

[debasisdas]

you need to check the system date and compare with desired date on start up

Stick with the registry method, for it will allow you to make exe's expire with respect to date or number of trials.

Do NOT use the registry. As a new programmer you may destroy your system.

As debasisdas said, "The simplest thing to do is to check system date on start up." Which means you need to look up the Date functions in VB. There are at least 2 that will help you.

thanx waltP for alerting me but how do i check the date

[debasisdas]

try this

Dim dtmTest As Date
dtmTest = DateValue(Now)

next you need to compare the date with desired date using DateDiff.

Do you understand those statements?
