I heed help as to how to Login User and validate user based on Date Entries in MS Access Database Using ASP VBScript. I have two coloumns in my MS Access Database. 1. Registerd On Date 2. Expire Date. I want To login the user and check whether the current date is less than the expiration date in the expire date coloumn. and if it is less then login him to the correct page or else redirect him to a error page .
