MultimediaSupport Class

Summary

Unlocks the Multimedia features, filters, codecs and objects.

Note

As of v21 the LEADTOOLS Multimedia toolkit has been updated to use a seamless license mechanism and any new development must use it. The new licensing mechanism uses RasterSupport.SetLicense. For a step-by-step tutorial on a .NET platform, refer to Add References and Set a License.

The UnlockModule mechanism is still supported in v21.

Syntax

C++/CLI

public static class MultimediaSupport

public ref class MultimediaSupport abstract sealed

Remarks

This is a static class, so it does not need to be created. This class is internally calling the DSKERNEL2.DLL ILMDSKernel2 interface. So you can either call the methods in this class or use the ILMDSKernel2 interface directly.

A typical use is to call UnlockModule when the application starts and LockModules at before the application exits.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
 
public void MultimediaSupportExample() 
{ 
   // 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.Multimedia.Common.MultimediaSupport.UnlockModule(pszKey, 
                                                                 Leadtools.Multimedia.Common.LockType.Application, 
                                                                 pszAppId); 
   } 
   catch 
   { 
      return; 
   } 
 
   // [use the multimedia feature here] 
 
   // lock the multimedia feature before exiting the app 
   try 
   { 
      Leadtools.Multimedia.Common.MultimediaSupport.LockModules(Leadtools.Multimedia.Common.LockType.Application, 
                                                                pszAppId); 
   } 
   catch 
   { 
      return; 
   } 
   _result = true; 
}
