ASP » Application » Lock


The Lock method prevents all other users from making changes in the Application object.

The Lock method prevents all other users from changing any of the variables in the Contents collection of the Application object.

Application objects are designed to be shared among an unlimited number of users. Therefore, you need the ability to allow only one user at a time to make changes and you do this by locking everybody else out.

You can use the Unlock method to explicitly remove the Lock placed upon the Application object. Remember, to completely unlock an object, you must call Unlock the same number of times you have called Lock. Fortunately, the server will automatically unlock all locks placed on the object when the script times out or the .asp file ends.
