Java

using Leadtools; 
 
 
public void SetLicenseFileExample() 
{ 
#if DEBUG 
	LicenseSupport.SetLicense(); 
#else 
	string MY_LICENSE_FILE = @"leadtools.lic"; 
	string MY_DEVELOPER_KEY = "xyz123abc"; 
	RasterSupport.SetLicense(MY_LICENSE_FILE, MY_DEVELOPER_KEY); 
#endif 
	bool isLocked = RasterSupport.IsLocked(RasterSupportType.Document); 
	if (isLocked) 
		Console.WriteLine("Document support is locked"); 
	else 
		Console.WriteLine("Document support is unlocked"); 
}
