Hi Mudassar.
Welcome to Bytes.com.
It's always very hard to write questions clearly in a foreign language so I'm not really sure what it is you're asking for.
If you want to ensure that users cannot open your project using the
Bypass key (Shift) then
How to Enforce or Disable the Startup Options (BypassKey) in an Access Database should help with that.
I can see nowhere where this is possible using the interface directly - in either pre- or post-2007 versions.
If you mean something else then I'll need some help understanding what that is.
