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.
Public Overloads Shared Sub SetLicense( _
ByVal licenseBuffer() As Byte, _
ByVal developerKey As String _
+ (BOOL)setLicenseData:(NSData *)licenseData
Byte array containing the LEADTOOLS runtime license to set.
Character string containing the developer key.
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).
public void SetLicenseByteArrayExample()
byte license = System.IO.File.ReadAllBytes(MY_LICENSE_FILE);
bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document);
Console.WriteLine("Document support is locked");
Console.WriteLine("Document support is unlocked");
Public Sub SetLicenseByteArrayExample()
Dim license() As Byte = System.IO.File.ReadAllBytes(MY_LICENSE_FILE)
Dim isLocked As Boolean = RasterSupport.IsLocked(RasterSupportType.Document)
If (isLocked) Then
Console.WriteLine("Document support is locked")
Console.WriteLine("Document support is unlocked")
