Hi there,

I am currently building a proof of concept application for a client and I'm trying to integrate the RadCaptcha control into a webpart I am creating for a MOSS 2007 web site, and I'm having a problem with it, being that the image for the CAPTCHA is always broken.

I have added the following to my web.config file:

    
            <httpHandlers> 
        
            <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Version=2009.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" verb="*" validate="false" /> 
        
            </httpHandlers>

and:

    
            <handlers> 
        
            <add name="Telerik_Web_UI_WebResource_axd"  verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd"  type="Telerik.Web.UI.WebResource, Version=2009.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" /> 
        
            </handlers>

The reason I am fully qualifying the assembly name is because I am putting the Telerik DLL's in the GAC (both Telerik.Web.UI and Telerik.Web.Design - I have checked the version numbers and they match)

I am creating the RadCaptcha control in code like this:

    
            protected override void CreateChildControls()  
        
            {  
        
                // ...  
        
                RadCaptcha captcha = new RadCaptcha();  
        
                Controls.Add(captcha);  
        
                // ...  
        
            }

Any ideas why it isn't creatng the image for me? Help is appreciated

Further to the above, here is the error I have found that I am getting when the images are trying to load:

Configuration Error

Wow - just had a total brain snap moment there - had another look at my config line and realised I was typing it wrong :-)

Here is what should have been in the web.config for anyone who is interested

    
            <httpHandlers> 
        
            <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2009.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" verb="*" validate="false" /> 
        
            </httpHandlers> 
        
            <handlers> 
        
            <add name="Telerik_Web_UI_WebResource_axd"  verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd"  type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2009.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" /> 
        
            </handlers>

I'll return to my village in shame now :-P
