Clearscreen CAPTCHA Control v1.4 Released with Community Server 1.0 support [UPDATED]

I've updated the Clearscreen.SharpHIP control to solve most of the reported issues. The new features and fixes for this release are:

Bug Fixed: Enabled deletion of comments in .Text versions for logged admins
Bug Fixed: Use of IsValid property is now working correctly
Bug Fixed: Session and ViewState values for ValidationForm where mistyped on the code and where not working correctly.
New features added:
- Removed captcha at all when an admin or trusted used is logged in
- Added support and compatibility for the new Community Server v1.0
- Added help to install on Community Server v1.0
- Added JavascriptURLDetection property (bool) to use Javascript or Server
- side code to detect the URL that should be used in the image source.

Follow the link to download: Clearscreen SharpHIP HIP-CAPTCHA Control v1.4 for ASP.NET

Hope that this new release helps to solve most of the actual issues, but if you find any bug or have any improvement that wasn't contained within this version, contact me and I'll try my best to solve it.

UPDATE: I updated the control to solve a reported error with image generation and javascript on some situations where the page that host the control has a formal querystring. The update is included in the zip file. [05/04/2005 21:00 GMT+1]

I love this control! I'm still having trouble with the updated version however. Seems to work fine when I go directly to my .95 blog post, but when I click the feedback link, the image box shows up as a broken image. Is the zip in this blog entry correct?

Is it possible to make this image render without having javascript on? For some reason with the default example given firefox wont display the image and it says its protected. However I can see the image just fine on your site. I enabled javascript and then my application displayed the image in firefox. Where can I look up the reference or set for this?

Oh I also forgot, this doesn't put out valid HTML code. The control should be looked at so it outputs correctly.

I just grabbed the new version and in debugging, I see that it triggers the Page_Load event twice. Then, if I hide the control and try to capture an event on another button, it's ignored and triggers Page_Load twice again and IsPostBack is set to False. What's going on here?

Michael, Do you have both the AutoEventWireUp set to true AND an explicit event handler set up in the code behind on your page? I've seen that behavior when both are true.

This is a destructive control. If you accidently type in the wrong code, you lose your comments and have to type them in again. Isn't there a way to turn the Comments textbox ViewState on?

This is my third time trying to post this comment with no apparent result. I hope I'm not adding multiples!

I installed the DLL onto my .Text .95 site tonight. I copied the DLL, added the Register tag to the PostComment.ascx file, and the actual cc1:HIPControl element. I get no error, but it doesn't show up either. I can change other elements and see the change so I know that I've got the right files.

Any ideas?

This was quite easy to implement and I was also able to get around the missing image reference for Feedback by modifying the dotText sourcecode to remove #Feedback from the URL. This is found in the UI Controls, day.cs to be exact.

Nice job Miguel! Couple of implementation items, all of which I'd be happy to help out with.

First is a strange bug that if a user clicks on the feedback link of a post (that goes right to #comments), the image does not show up. All other ways it does. Strange.

Second, it doesn't seem the persist user comments is working right if they enter a bad code. Is this by design?

Third is a request; can the code text be exposed in a way that a validation control can work with it? That way, if the user leaves it blank it won't blow away their message.

All tiddles aside, nice job and THANKS!

I'm running CS 1.0 and I can't get anything past 1.1 of your control to work for me. For 1.2 onward the first time the page loads the image is always broken. If the page posts back the image appears.

# Fix for broken image

6/26/2005 5:47 AM | Steven Padfield

I discovered a way to fix the "broken image" problem without having to modify the CAPTCHA or dotText binaries. I created a script that retroactively removes any bookmark specifier from the url of the IMG tag.

Simply include this script after your HIPControl declaration:

<cc1:HIPControl id="HIPControl1" runat="server" />
<script defer>
var hcImage = document.getElementById('PostComment.ascx:HIPControl1hcimage');
var hIndex = hcImage.src.indexOf('#');
var qIndex = hcImage.src.indexOf('?');
if (hIndex > 0 && qIndex > hIndex)
hcImage.src = hcImage.src.substring(0, hIndex) + hcImage.src.substring(qIndex, hcImage.src.length);
</script>

Please replace 'PostComment.ascx:HIPControl1hcimage' with '{ContainingFileName}:{HIPControlID}hcimage'.

I'm not a big fan of CAPTCHA to be honest. I suppose no one really is; we don't exactly have the CAPTCHA because its nice, only because it can stop bots. So, if I'm going to have a CAPTCHA anywhere I would probably consider the RECAPTCHA idea – where the words typed in get stored in a database to help old books to be restored. Now, that's a really cool idea, and a totally commendable one. The guy who came up with it is really clever if you ask me.
