Setting a Runtime License

In order to legally use LEADTOOLS and unlock support for the features that you have purchased, you must provide a runtime license in your source code when you compile your application.  If you do not provide a runtime license, your application will display a "nag" message at runtime. You can develop your application without providing a runtime license, but you cannot redistribute your application to your end-users.

The LEADTOOLS runtime licence consists of a LICENSE file and a developer key.  Both of these are unique to each customer.  The runtime license identifies which LEADTOOLS products and features you are allowed to use.  To obtain a runtime license and developer key, contact sales@leadtools.com.

After you have obtained a runtime license, use the following functions to set the license in your application's source code:

• LSettings::SetLicenseFile - sets a runtime license for LEADTOOLS from a file on disk.

• LSettings::SetLicenseBuffer - sets a runtime license for LEADTOOLS from a memory buffer that contains the license.

To detect whether or not the LEADTOOLS kernel evaluation period has expired, use the LBase::KernelHasExpired function.
