i want my software can be available to few of the users those who got the key. and one more thing is that depending on the key values too, the menu activation depends. i mean for a key value they may use the software for just evaluation. if they give some other key they will get some deepest level of software accessing and so on...
one more problem is that the software should work for limited executions or for the limited time period.
Is there any control or dll to do so. or is there any other method to do so.
please help. ur suggestions and replys will be appreciable and encouragable.
