UPDATE: (12/22/2006) There is now a mod to use an improved beta version of this captcha solution. Please try that version 1st as it is a stronger captcha.

(Capcha Security Image Mod)

This mod will add a Capcha Security Image to the registration signup form. Perhaps not the most powerful implementation of one but good enough unless your running some HUGE/CRAZY site and someone actually takes the time to set up an OCR scanning submision to hit your site.



Instructions:

Download Version 1.0 of the ASP Security Image Generator from this site. http://www.tipstricks.org/

Unzip that download and copy "aspcaptcha.asp" and "aspcaptcha_distort.asp" into the aspprotect "users" folder.

Now edit "users/register.asp" with a text editor and add the code shown below in blue. The code to add goes near the bottom of the form right above the submit button. Just add the blue code. The code around it is shown to help you find the area of code where it gets placed.


    <tr>
      <td valign="top" align="right"><font face="Arial" size="2"><strong>
  Newsletter</strong></font></td> ; ; ; ; ; ; ; ; ; ; ; ;
      <td valign="top">
  <input type="checkbox" name="Newsletter" value="True" checked>
  <font face="Arial" size="1">Do you want to be subscribed to the
  newsletter ?</font></td>
    </tr>

    <tr>
      <td valign="top" align="right"></td>
      <td valign="top">&nbsp;<img src="aspcaptcha.asp" alt="" width="86" height="21" />
   <font face="Arial" size="2" color="#000000">Type the characters shown in image for verification.</font><br>
   <input name="strCAPTCHA" type="text" id="strCAPTCHA" maxlength="8" /></td>
    </tr>

    <tr>
      <td colspan="2" bgcolor="#FFFFFF">
        <p align="center"><input type="submit" value="Register"></p>
      </td>
    </tr>


ok, now edit "users/add_new_account.asp" with a text editor and add the code shown below in blue. Just add the blue code. The code around it is shown to help you find the area of code where it gets placed.

If User_Custom6_Used = True Then
 If User_Custom6_Required = True Then
  If  Custom6 = "" Then
   ErrorMessage = ErrorMessage & Server.URLEncode("You need to enter a " & User_Custom6_Name &".\n\n")
  End IF
 End If
End If
 
 strCAPTCHA = Trim(Request.Form("strCAPTCHA"))
 if strCAPTCHA = Trim(Session("CAPTCHA_" & Session.SessionID)) then
 else
  ErrorMessage = ErrorMessage & Server.URLEncode("You did not type in the verification info correctly.\n\n")
 End If 
 
If ErrorMessage <> "" Then
 Response.Redirect "register.asp?" & Request.Form & "&ErrorMessage=" & ErrorMessage
 Response.End
End If

Your done. You just added a Capcha Security Image to your signup form. If you would like a more distorted image that is more difficult for an automated program to figure out change the image tag to call the "aspcaptcha_distort.asp" page instead. It will look more like this.

I updated the two files as per the instructions but cannot get the verification to work for the life of me!

I keep getting the 'You did not type the verification info correctly' message. Any ideas? Anybody else have had a similar problem? What did you do?

Thanks!
