UnlockFlagsConstants2 Enumeration Constants

The UnlockFlagsConstants2 constants define the level at which unlocking will be performed.

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 L_SetLicenseFile and L_SetLicenseBuffer. For a step-by-step tutorial on a C DLL platform, refer to Add References and Set a License.

The ILMDSKernel2::UnlockModule mechanism is still supported in v21.

typedef enum UnLockFlagsConstants2 
{ 
   UNLOCK_COMPUTER = 0x01, 
   UNLOCK_APP_ONCE = 0x02, 
   UNLOCK_APP_ALWAYS = 0x03, 
   UNLOCK_APP_PATH = 0x04, 
   UNLOCK_MM = 0x80000000 
} UnLockFlagsConstants2;
