ASP Application.Lock Method

By Mike Prestwood

Posted 17 years ago on 11/14/2006 and updated 1/29/2009

Take Away:

Call Application.Lock to freeze ASP code while you set IIS application variables the Application.Unlock to unfreeze. No actions take place on the server while locked.

Application.Lock

Application(YourAppVar) = AValue
Application.Unlock

Example

Use the Application.Lock method to lock the application object so that no actions take place on the server. For example, when you change a recordset that is kept in memory. Use Application.Unlock to unlock the application object and allow the continuation of ASP code.

Application.Lock

Application(AppVarDateTime) = Now
Application.Unlock

While the Application object is locked, no ASP code is executed and no ASP pages are served to visitors. If you do not unlock the application it will remain locked!

"While the Application object is locked, no ASP code is executed ..." -- seriously?! So how would "Application.Unlock" ever get executed?
