Parameter |
Description |
pszLicenseFile |

Before calling this function, call LBase::LoadLibraries(LT_KRN).
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.
NOTE:
In order to obtain a runtime license and developer key, you must contact LEAD. For more information, refer to About LEADTOOLS Deployment Licenses.
For information about LEADTOOLS Document/Medical capabilities, contact LEAD.
To determine if support for optional features has been unlocked, use the LSettings::IsSupportLocked function.
To set the runtime license from a memory buffer instead of a disk file, use the LSettings::SetLicenseBuffer function
Note: To avoid receiving WRPERR_LTKRN_DLL_NOT_LOADED return value, ensure that LBase::LoadLibraries(LT_KRN) is called prior to calling this function.
