LockModules Method

Example 





One of the LockType enumeration values that specify the level at which the locking operation will be performed. It should be the same value passed to UnlockModule.
If type is set to LockType.Application or LockType.Computer, appId should be the application ID; a unique ID of the calling application. The caller is responsible for uniqueness of this ID. It is recommended to use the full path of the application.

If type is set to LockType.ApplicationPath, appId should be the application full path of the application (the long version, not the short 8.3 version of the path).

This parameter cannot be NULL (empty).

Locks all modules of the same appId that were unlocked using UnlockModule.
Syntax
public static void LockModules( 
   LockType type,
   string appId
)
'Declaration
 
Public Shared Sub LockModules( _
   ByVal type As LockType, _
   ByVal appId As String _
) 
'Usage
 
Dim type As LockType
Dim appId As String
 
MultimediaSupport.LockModules(type, appId)
public static void LockModules( 
   LockType type,
   string appId
)
 function Leadtools.Multimedia.Common.MultimediaSupport.LockModules( 
   type ,
   appId 
)
public:
static void LockModules( 
   LockType type,
   String^ appId
) 

Parameters

type
One of the LockType enumeration values that specify the level at which the locking operation will be performed. It should be the same value passed to UnlockModule.
appId
If type is set to LockType.Application or LockType.Computer, appId should be the application ID; a unique ID of the calling application. The caller is responsible for uniqueness of this ID. It is recommended to use the full path of the application.

If type is set to LockType.ApplicationPath, appId should be the application full path of the application (the long version, not the short 8.3 version of the path).

This parameter cannot be NULL (empty).

Remarks
You must call LockModules:
