SetLicense(byte[],string) Method

Summary

Sets the runtime license for LEADTOOLS and unlocks support for optional features such as LEADTOOLS Imaging Pro, Document, and Medical capabilities. After you have obtained a runtime license and a developer key, you can call Leadtools.RasterSupport.SetLicense in your application to disable the nag message.

Syntax

Objective-C

C++

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

Public Overloads Shared Sub SetLicense( _ 
   ByVal licenseBuffer() As Byte, _ 
   ByVal developerKey As String _ 
)

+ (BOOL)setLicenseData:(NSData *)licenseData 
          developerKey:(NSString *)developerKey 
                 error:(NSError **)error

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

Parameters

licenseBuffer
Byte array containing the LEADTOOLS runtime license to set.

developerKey
Character string containing the developer key.

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 disk file instead of memory buffer, use SetLicense(string licenseFile, string developerKey).

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
public void SetLicenseByteArrayExample() 
{ 
   byte[] license = System.IO.File.ReadAllBytes(MY_LICENSE_FILE); 
   RasterSupport.SetLicense(license, MY_DEVELOPER_KEY); 
   bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document); 
   if (isLocked) 
      Console.WriteLine("Document support is locked"); 
   else 
      Console.WriteLine("Document support is unlocked"); 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing 
 
Public Sub SetLicenseByteArrayExample() 
   Dim license() As Byte = System.IO.File.ReadAllBytes(MY_LICENSE_FILE) 
   RasterSupport.SetLicense(license, MY_DEVELOPER_KEY) 
   Dim isLocked As Boolean = RasterSupport.IsLocked(RasterSupportType.Document) 
   If (isLocked) Then 
      Console.WriteLine("Document support is locked") 
   Else 
      Console.WriteLine("Document support is unlocked") 
   End If 
End Sub
