   Implements System.IComparable, System.IConvertible, System.IFormattable

'Usage

Dim instance As LockType

public enum class LockType : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable

Value	Member	Description
0x00000001	Computer	Unlocks the module at the computer level. Unlocking at the computer level should be avoided because it can cause unexpected behavior in other applications.
0x00000002	Application	Unlocks the module for this instance of the application. This is the recommended value.
0x00000004	ApplicationPath	Unlocks the module for this particular application. Use this for unlocking support in a third party application (like Windows Media Player).

The MultimediaSupport.UnlockModule and MultimediaSupport.LockModules methods use a parameter of this type to indicate how to unlock or lock multimedia features.
