Dutch Localized CAPTCHA Images

Example Captcha images generated by BotDetect using the base Latin character set for all Captcha ImageStyle values can be seen in the BotDetect Captcha image styles demo

To use BotDetect Captcha images localized for the Dutch Captcha Locale in your application, you can specify the Locale value:

  • In ASP.NET applications, you can use either the .aspx page source:
    <!-- Captcha control localized to Dutch -->
    <BotDetect:WebFormsCaptcha ID="ExampleCaptcha" runat="server" Locale="nl" />
    or the page code-behind:
    [C#]
        
    // Set the Captcha instance Locale to Dutch    
    ExampleCaptcha.Locale = "nl";
    [VB.NET]
        
    ' Set the Captcha instance Locale to Dutch    
    ExampleCaptcha.Locale = "nl"

    or Locale-dependent Captcha strings can be configured on application level in the <botDetect> Web.config configuration section:

    <botDetect locale="nl" 
  • In Java applications, you can use either the application web.xml configuration file setting:
    <context-param>
      <param-name>BDC_locale</param-name>
      <param-value>nl</param-value>
    </context-param>
    
    or the Captcha object instance-specific value:
    exampleCaptcha.setLocale("nl"); 
    
    or Stannlrd / Facelets JSF Captcha Tag page source:
    <botDetect:jsfCaptcha id="exampleCaptcha" locale="nl"
    
    or JSP Captcha Tag page source:
    <botDetect:captcha id="exampleCaptcha" locale="nl"
    
  • In ASP Classic applications, you can use either the application-global setting in the BotDetect\CaptchaConfig.asp file:
    ' Set the default Locale for all Captcha instances in the 
    ' Classic ASP application to Dutch
    BotDetect.Locale = "nl"
    or the Captcha object instance-specific value:
    <%
      Dim ExampleCaptcha : Set ExampleCaptcha = (New Captcha)("ExampleCaptcha")
      ExampleCaptcha.UserInputID = "CaptchaCode"
      ' Set the Captcha object instance Locale to Dutch
      ExampleCaptcha.Locale = "nl"
      Response.Write ExampleCaptcha.Html
    %>
  • In PHP applications, you can use either the application-global setting in the lib/botdetect/CaptchaConfigDefaults.php file:
    // Set the default Locale for all Captcha instances in the 
    // PHP application to Dutch
    $BDC_CaptchaConfig->Locale = 'nl';
    or the Captcha object instance-specific value:
    <?php 
      $ExampleCaptcha = new Captcha("ExampleCaptcha");
      $ExampleCaptcha->UserInputID = "CaptchaCode";
      // Set the Captcha object instance Locale to Dutch
      $ExampleCaptcha->Locale = 'nl';
      echo $ExampleCaptcha->Html(); 
    ?>

Dutch Localized Audio CAPTCHA Sounds

Example audio Captcha sounds generated by BotDetect using the Dutch Locale setting can be heard in the BotDetect Captcha features demo

To use BotDetect sounds localized for the Dutch Captcha Locale, you should also download the Dutch Pronunciation Sound Package and deploy the .bdsp file to the BotDetect sounds folder your application uses:

  • ASP.NET applications use Bin\BotDetectSounds by default. A custom folder can be specified in the <botDetect> configuration section.
  • Java applications use WEB-INF\BotDetectSounds by default. A custom folder can be specified in the web.xml configuration file setting.
  • ASP Classic applications use Redistribute\BotDetectSounds in the BotDetect installation folder by default. A custom folder can be specified in the BotDetect/CaptchaConfig.asp file.
  • PHP applications always use lib/botdetect/Resources/Sounds.

Dutch Localized CAPTCHA Codes

The nl-NL Captcha locale uses the default Latin character set, consisting of 26 characters.
