if (errorCode != DM_OK)
   cout << szErrorMsg << endl;

LicenseManager.initLicense("--Enter Your License Key Here--", MainActivity.this, new LicenseVerificationListener() {
   @Override
   public void licenseVerificationCallback(boolean isSuccess, CoreException error) {
          if(!isSuccess){
             error.printStackTrace();
          }
   }
});

[DynamsoftLicenseManager initLicense:@"--Enter Your License Key Here--" verificationDelegate: self];
- (void)licenseVerificationCallback:(BOOL)isSuccess error:(NSError *)error{
   // Add your code to execute when license verification call back is handled.
}

DynamsoftLicenseManager.initLicense("--Enter Your License Key Here--", verificationDelegate: self)
func licenseVerificationCallback(_ isSuccess: Bool, error: Error?) {
   // Add your code to execute when license verification call back is handled.
}

int errorCode = 0;
string errorMsg;
errorCode = LicenseManager.InitLicense("--Enter Your License Key Here--", out errorMsg);
if (errorCode != (int)EnumErrorCode.EC_OK && errorCode != (int)EnumErrorCode.EC_LICENSE_CACHE_USED)
{
    Console.WriteLine("License initialization error: " + errorMsg);
}
else
{
    CaptureVisionRouter cvr = new CaptureVisionRouter();
    // add code for further process
}

error_code, error_msg = LicenseManager.init_license("--Enter Your License Key Here--")
if error_code != EnumErrorCode.EC_OK.value and error_code != EnumErrorCode.EC_LICENSE_CACHE_USED.value:
    print("License initialization error: " + error_msg)
else:
    CaptureVisionRouter cvr = new CaptureVisionRouter()
