Character string containing the name of the LEADTOOLS runtime license file to load.

Remarks

You must use this method 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 RELEASE 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 IsLocked.

NOTE: As an alternative to calling RasterSupport.SetLicense, you can specify your runtime license in the Leadtools.dll.config file. For more information, see LEADTOOLS Config License.

To set the runtime license from a memory buffer instead of disk file, use SetLicense(byte[] licenseBuffer, string developerKey).

Example

For an example, refer to RasterSupport.
