Uses a zip utility program to extract the files to your hard drive keeping the original file structure intact.

Extract files using a zip extraction tool

The files named 'example.asp' and 'example_process_form.asp' are ONLY examples files of how Web Wiz CAPTCHA works and can be safely deleted.

Place the folder, and it's contents, named 'CAPTCHA' into the same website directory as the web page you wish to integrate Web Wiz CAPTCHA is within.

The web page that contains the HTML web form you wish to integrate Web Wiz CAPTCHA into and the page that process the web form submission must have an .asp extension (eg. my_web_form.asp and my_submit_process.asp (these are example file names and not a real files))

Open your file (web page) that contains your 'web form' in a text editor and place the following code at the top of the file (not within ASP blocks):-

Example:


	<!-- Include file for CAPTCHA configuration --> <!-- #include file="CAPTCHA/CAPTCHA_configuration.asp" --> <html> <head> <title>My Form Submission Page</title>

In the same file place the following code into the part of your form where you wish the CAPTCHA image to be displayed within your 'web form':-

Example:


	<form action="example_process_form.asp" method="post" name="myForm" id="myForm"> Name: <input type="text" name="name" id="name" /> <!-- include the Web Wiz CAPTCHA form element --> <!--#include file="CAPTCHA/CAPTCHA_form_inc.asp" --> <input name="Submit Form" type="submit" id="Submit Form" value="Submit" /> </form>

Next open the file (web page) in a text editor that is to process your web form input and place the following code at the top of the file (not within ASP blocks):-

Example:


	<!-- Include file for CAPTCHA configuration --> <!-- #include file="CAPTCHA/CAPTCHA_configuration.asp" --> <!-- Include file for CAPTCHA form processing --> <!-- #include file="CAPTCHA/CAPTCHA_process_form.asp" --> <html> <head> <title>My Form Submission Page</title>

Within the file you entered the code from the last step into you can call the following variable to check that the CAPTCHA code entered is correct.

blnCAPTCHAcodeCorrect

If the CAPTCHA code entered is correct the above variable with be set to True, if the CAPTCHA code has not been entered correctly the variable will be set to False.

Below is some sample code to check the CAPTCHA code is correct:-


	<% 'If CAPTCHA is entered correctly run the following code If Request("CAPTCHA_Postback") AND blnCAPTCHAcodeCorrect = True Then 'Place code here that is to run if CAPTCHA is entered correctly Response.Write("CAPTCHA code is correct") 'If CAPTCHA is NOT entered correctly run the following code ElseIf Request("CAPTCHA_Postback") AND blnCAPTCHAcodeCorrect = False Then 'Place code here that is to run if CAPTCHA is NOT entered correctly Response.Write("CAPTCHA code is NOT correct") End If %>
