I have implemented as writeen in the aritcle but the captcha image is not being shown when I run the application.why
Despite inputting the wrong answer for the captcha control, it did not display an error message..
protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
MSCaptcha.CaptchaControl Captcha1 = (CreateUserWizardStep1.ContentTemplateContainer.FindControl("Captcha1") as MSCaptcha.CaptchaControl);
TextBox txtCaptcha = (TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl("txtCaptcha");
Captcha1.ValidateCaptcha(txtCaptcha.Text.Trim());
[Code] .....
Here is the code:
[Code]....
code behind:
[Code]....
The problem is that if the textcap changetext event is fired which is in the updatepannel then the captcha will always validate to false. If the textcap changetext event is not fired then all goes well.
I have implemented captcha in my Register.aspx page. I am verifying captcha at server side. here is the code which is working fine.
protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
bool IsCaptcha;
IsCaptcha = validateCaptcha();
if (IsCaptcha == true)
StringBuilder bodyMsg = new StringBuilder();
TextBox textBoxUserName = (TextBox)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("UserName");
[code]...
I m using your Captcha Code [URL]. This code is working at local system but not working on Server Side. Captcha Image is not Displaying any Code.
View 1 RepliesI tried this link to generate verification Image [URL] ..... It works fine.
But I'd like to put a button in page for regenerating captcha for example. When the image was unreadable for user.
So I put an updatepanel in page and this is my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<tr> <td colspan="2">
<asp:Image ID="imCaptcha" ImageUrl="~/Captcha.ashx" runat="server" />
[Code] .....
Although the image changes but the whole page is refreshed. Whether this is due to incompatibilities httphandler and updatepanel?
I want to create a simple user registration form with First / Last name, email, and password. We have used captcha and email verification in the past to ward off bots, but is there another way without using those techniques? I thought about encrypting the field ID names so that they aren't names username, password, etc. we tried openID, but 1% of our users had an ID they could use.

View 4 RepliesHow to implement captcha in ASP.NET. I've a strange scenario where the captcha letter is showing correctly but the background image(the black dots) is not displaying.I checked it by using firebug in firefox,to my surprise i found that an additional div(which i have not written) is enclosing the captcha,and its background color is set to white.This is how i placed the captcha inside the form tag in aspx page
<div id="divCaptcha">
<cc1:CaptchaControl ID="Captcha1" runat="server" CaptchaBackgroundNoise="none" CaptchaLength="5"
CaptchaWidth="200" CaptchaLineNoise="none" CaptchaMinTimeout="5"
CaptchaMaxTimeout="240" FontColor="#529E00" CaptchaHeight="60"/> </div>
This is what i got when i checked using the firebug
<div id="divCaptcha">
<div style="background-color:White;">
<img width="200" height="60" border="0" src="CaptchaImage.axd?guid=1e625862-4447-41ff-a6a5-86ad1e95261a">
</div></div>

View 10 RepliesI have a blank page with a Captcha called Captcha.aspx. I would like to add this as the second step to a CreateUserwizard. The following is what I want to achieve:i) User enters their Username etc in CreateUserwizard and clicks the CreateUser Button(ii) After clicking the CreateUser button, user sees the Captcha.aspx page and enters the correct stuff in the Captcha box and click a continue button(iii) User account is created if correct details were entered in the Captcha else no account is created, rather the user is sent to a page informing him or her that no account has been created
