LockModules Method

Summary

Locks all modules of the same

appId that were unlocked using UnlockModule.

Syntax

C++/CLI

public static void LockModules( 
   LockType type, 
   string 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:

When the application terminates, if unlocking was performed at the application level using LockType.Application.
When uninstalling the application, if unlocking was performed at the computer level using LockType.Computer or LockType.ApplicationPath.

using Leadtools;

   // pszKey is a string containing the serial number. It is defined like this: 
   // string pszKey = "MySerial"; 
   string pszAppId = "My Test Application"; 
 
   try 
   { 
      // unlock the multimedia feature 
      Leadtools.MediaFoundation.Common.MultimediaSupport.UnlockModule(pszKey, 
                                                                 Leadtools.MediaFoundation.Common.LockType.Application,
