Comments
You must use this function to set the runtime license for LEADTOOLS and to unlock support for any optional features that you have licensed. If you do not set a runtime license, your application will display a "nag" message dialog at runtime, indicating that you have developed the application without a valid runtime license.
In order to obtain a runtime license and developer key, you must contact LEAD. For more information, refer to About LEADTOOLS Runtime Licenses.
For information about LEADTOOLS Document/Medical capabilities, contact LEAD.
To determine if support for optional features has been unlocked, use the L_IsSupportLocked function.
To set the runtime license from a memory buffer instead of a disk file, use the L_SetLicenseBuffer function.
