Security Exception When Trying To Render A ReCaptcha Control

Oct 29, 2010

I've downloaded the recaptcha.dll in both 1.0.1.0 and 1.0.4.0. When trying to render the control, I get the following exception: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. Stack Trace:[SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]System.Reflection.Assembly._GetType(String name, Boolean throwOnError, Boolean ignoreCase) +0System.Web.UI.NamespaceTagNameToTypeMapper.GetControlType(String tagName, IDictionary attribs, Boolean throwOnError) +209

The solution to this, as provided by a quick Googling, is to use caspol.exe to add full trust to the recaptcha.dll assembly. C:\%path%caspol -af C:inetpubwwwroot\%path%in ecaptcha.dll At this point, I get the following error: ERROR: This assembly is not strong name signed Short of downloading the source code and recompiling it locally, is there any other way to get this working?

Web Form Render Engine Outputs A Control Tree / Looking For Info On Render Logic.

Feb 12, 2011

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).

I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

Web Forms :: To Use ReCAPTCHA Control In A CreateUserWizard?

Sep 22, 2010

I have a CreateUserWizard where there are two plain WizardSteps, then the CreateUserWizardStep, then CompleteWizardStep. In the CreateUserWizardStep I would like to use a reCAPTCHA control. Obviously when I go to the first plain WizardStep the reCAPTCHA control is invalid. So when I click the Next button from the first WizardStep the form isn't valid and I can't progress. I'm not sure how to handle this situation.

Custom navigation template somewhere maybe?

Recaptcha Being Triggered From Masterpage Control?

May 17, 2010

I have a master page which contains a Login control so that the user can login/logout from any page. However, a couple of content pages require a Recaptcha control. This causes problems because when I try and log in on a page that has the Recaptcha control, the system expects me to enter the words. I'm aware of the lack of validation groups in the Recaptcha control, and the fact that you can't have multiple forms on an ASP.NET page. Is there a way to work around this? A 'hacky' way I can think of, is in the "Login" event, check the page for a Recaptcha control. If one exists, then disable it, otherwise continue. However, that just seems quite inefficient especially when there are quite a few pages and most won't have a Recaptcha control.

C# - Render Multiple Control Collections In Custom Control?

Mar 15, 2010

I've build a custom WebControl, which has the following structure:

<gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server">
<Contents>
<asp:Label ID="KeywordLabel" AssociatedControlID="KeywordTextBox" runat="server">Keyword: </asp:Label><br />
<asp:TextBox ID="KeywordTextBox" Text="" runat="server" />

[Code]....

However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property (see above asp.net code). I'll get the HttpException:

Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'.

Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently?

AJAX :: HTMLEditor And Security Exception Error "System.Security.SecurityException: Request Failed"

Oct 21, 2010

I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Recaptcha ErrorMessage Property?

Jan 25, 2010

I am using recaptcha in an ASP.NET 3.5 application and for some odd reason the ErrorMessage property is not working. Below is my code

<recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="*******************************" PrivateKey="*******************" Theme="white" ErrorMessage="This is an typo error" />

When the typed text doesn't match with the recaptcha image text it still shows the default error message "Incorrect. Try again." instead of my custom error message. What could be the reason for this strange behavior

C# - Set Recaptcha Key Settings At Runtime?

Jun 25, 2010

I'm implementing the recaptcha control from google.

I built a simple c# test project from their example and all works. Now, instead of having the PublicKey and PrivateKey in the aspx page, I'd rather assign these values at run time as they will most likely be pulled from either the web.config or a database table.

I tried the following in the Page_Load

protected void Page_Load(object sender, EventArgs e) {
recaptcha.PublicKey = "<deleted for obvious reasons>";
recaptcha.PrivateKey = "<ditto>";
}

but I get an error stating "reCAPTCHA needs to be configured with a public & private key."

I also tried overriding the oninit method of the page and assigning the values there, but no joy.

Validation - Recaptcha Asp.net Always Returns Invalid?

Mar 30, 2010

The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test).I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.

Web Forms :: Render A User Control As An Image?

Aug 2, 2010

I have a complicated user control on a form that's laid out they way the business unit wants it. What they would like is to be able to export this content to excel and/or PDF as an image. Basically I need to be able to render the user control as a static image.

Is there any simple way to do this or is it even possible? Since the user control is HTML, it's not really rendered at all at the server level as it's just HTML, so I would assume that I might need to interface with IE library.
