UAE Arabic Localized CAPTCHA Images

Example Captcha images generated by BotDetect using the base Arabic 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 UAE Arabic 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 UAE Arabic -->
    <BotDetect:WebFormsCaptcha ID="ExampleCaptcha" runat="server" Locale="ar-AE" />
    or the page code-behind:
    [C#]
        
    // Set the Captcha instance Locale to UAE Arabic    
    ExampleCaptcha.Locale = "ar-AE";
    [VB.NET]
        
    ' Set the Captcha instance Locale to UAE Arabic    
    ExampleCaptcha.Locale = "ar-AE"

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

    <botDetect locale="ar-AE" 

    Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:

    <asp:TextBox ID="CaptchaCodeTextBox" runat="server" dir="rtl"></asp:TextBox>
  • In Java applications, you can use either the application web.xml configuration file setting:
    <context-param>
      <param-name>BDC_locale</param-name>
      <param-value>ar-AE</param-value>
    </context-param>
    
    or the Captcha object instance-specific value:
    exampleCaptcha.setLocale("ar-AE"); 
    
    or Standard / Facelets JSF Captcha Tag page source:
    <botDetect:jsfCaptcha id="exampleCaptcha" locale="ar-AE"
    
    or JSP Captcha Tag page source:
    <botDetect:captcha id="exampleCaptcha" locale="ar-AE"
    
    Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:
    <input name="captchaCode" type="text" id="captchaCode" dir="rtl" />
  • 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 UAE Arabic
    BotDetect.Locale = "ar-AE"
    or the Captcha object instance-specific value:
    <%
      Dim ExampleCaptcha : Set ExampleCaptcha = (New Captcha)("ExampleCaptcha")
      ExampleCaptcha.UserInputID = "CaptchaCode"
      ' Set the Captcha object instance Locale to UAE Arabic
      ExampleCaptcha.Locale = "ar-AE"
      Response.Write ExampleCaptcha.Html
    %>

    Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:

    <input name="CaptchaCode" type="text" id="CaptchaCode" dir="rtl" />
  • 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 UAE Arabic
    $BDC_CaptchaConfig->Locale = 'ar-AE';
    or the Captcha object instance-specific value:
    <?php 
      $ExampleCaptcha = new Captcha("ExampleCaptcha");
      $ExampleCaptcha->UserInputID = "CaptchaCode";
      // Set the Captcha object instance Locale to UAE Arabic
      $ExampleCaptcha->Locale = 'ar-AE';
      echo $ExampleCaptcha->Html(); 
    ?>

    Since Arabic text is drawn right-to-left, you should also set the appropriate text direction on the textbox element used for Captcha code retyping:

    <input name="CaptchaCode" type="text" id="CaptchaCode" dir="rtl" />

UAE Arabic Localized audio CAPTCHA Sounds

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

To use BotDetect sounds localized for the UAE Arabic Captcha Locale, you should also download the UAE Arabic 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.

UAE Arabic Localized CAPTCHA Codes

The ar-AE Captcha locale uses the default Arabic character set, consisting of isolated forms of 28 standard characters.

Unicode Captcha Codes and Font Requirements

This table on the left uses the actual Unicode characters drawn in localized Captcha images.

Displaying these characters in your browser requires having fonts which support them installed on the client machine.

In ASP.NET and ASP Classic versions of BotDetect, generating localized Captcha images using these characters also requires supporting fonts on your server.

If viewing these characters in your browser or generating them in Captcha images on your server fails, you can enable the required localization support for on both client and server machines using Control Panel:

Windows 2000, XP, 2003 Server: Regional and Language Options → Languages → Supplemental language support.

Windows Vista, 7, 2008 Server: Region and Language → Keyboards and Languages → Install/uninstall languages.
