Restrict concurrent access to forms?

[RPrasad]

Hi,
I have Access DB with basic user login form, which looks up the user name from table stored within DB and allow the users to login. Also DB is split as Front end on users desktops and backend on network.
There are 4 forms and 8 users for the DB. Now the request is to restrict the access of forms to only one person at a time, two people should not be allowed to open the same form concurrently.
Example: If user A had opend the form and working on that, when the User B try to open the same form it should give the message that "User A is working on form, try later"
Is it possible to do this? Please help me.

If the end result of what you want to do is to prevent anyone from working with the same TABLE at one time, you need to set the record locking properties. See this article on Microsoft.com: http://office.microsoft.com/en-us/access/HP052408601033.aspx

The pertinent section:
All Records Microsoft Access locks all records in the form or datasheet (and underlying tables) you're editing for the entire time you have it open, so no one else can edit or lock the records. This strategy is very restrictive, so choose it only when you know you're the only person who needs to edit records at any one time.
