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 PHP applications, you can use either the application-global setting in the
lib/botdetect/CaptchaConfig.phpfile:// Set the default Locale for all Captcha instances in the // PHP application to Dutch $LBD_CaptchaConfig->Locale = 'nl';
or the Captcha object instance-specific value:<?php $SampleCaptcha = new Captcha("SampleCaptcha"); $SampleCaptcha->UserInputID = "CaptchaCode"; // Set the Captcha object instance Locale to Dutch $SampleCaptcha->Locale = 'nl'; echo $SampleCaptcha->Html(); ?>
- In ASP.NET applications, you can use either the
.aspxpage source:<!-- Captcha control localized to Dutch --> <BotDetect:Captcha ID="SampleCaptcha" runat="server" Locale="nl" />
or the page code-behind:[C#] // Set the Captcha instance Locale to Dutch SampleCaptcha.Locale = "nl";[VB.NET] ' Set the Captcha instance Locale to Dutch SampleCaptcha.Locale = "nl"Locale-dependent Captcha strings can be configured in the
<botDetect> Web.configconfiguration section. - In ASP Classic applications, you can use either the application-global setting in the
BotDetect\CaptchaConfig.aspfile:' Set the default Locale for all Captcha instances in the ' Classic ASP application to Dutch LBD_Configuration_Locale = "nl"
or the Captcha object instance-specific value:<% Dim SampleCaptcha : Set SampleCaptcha = (New Captcha)("SampleCaptcha") SampleCaptcha.UserInputID = "CaptchaCode" ' Set the Captcha object instance Locale to Dutch SampleCaptcha.Locale = "nl" Response.Write SampleCaptcha.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:
- PHP applications always use
lib/botdetect/Resources/Sounds. - ASP.NET applications use
Bin\BotDetectSoundsby default. A custom folder can be specified in the<botDetect>configuration section. - ASP Classic applications use
Redistribute\BotDetectSoundsin the BotDetect installation folder by default. A custom folder can be specified in theBotDetect/CaptchaConfig.aspfile.
Dutch Localized CAPTCHA Codes
The nl-NL Captcha locale uses the default Latin character set, consisting of 26 characters.
