public static void SetLicense( 
   byte[] licenseBuffer,

'Usage

RasterSupport.SetLicense(licenseBuffer, developerKey)

public static void SetLicense( 
   byte[] licenseBuffer,
   string developerKey
)

+(BOOL)setLicenseBuffer:(const unsigned char*)licenseBuffer 
                 length:(size_t)length 
           developerKey:(NSString*)developerKey 
                  error:(NSError**)outError;

 function Leadtools.RasterSupport.SetLicense(Byte[],String)( 
   licenseBuffer ,
   developerKey 
)

public:
static void SetLicense( 
   array<byte>^ licenseBuffer,
   String^ developerKey
)

Parameters

licenseBuffer: Byte array containing the LEADTOOLS runtime license to load.
developerKey: Character string containing the developer key.

Remarks

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 IsLocked

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

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.
