Ken Patrick – Code of the Week

There are many ways in .Net to implement a captcha element. The reason I designed this is because:

1. It’s easy.
2. Doesn’t annoy the user.
3. It’s effective!
4. User could copy and paste the captcha code.
5. User can be color blind and still read the captcha.

Here’s How:

add a label (lblCaptcha)and textbox (txtCaptcha)to your asp.net page.

add the following code to the page_load:

if (!IsPostBack)
{

//generate a random number for the captcha label

int MyRandom;
Random random = new Random();
MyRandom = random.Next(999, 999999);
string New_Random = MyRandom.ToString(“000000″);
lblCaptcha.Text = New_Random;
}

on your btnsend event add the following code:

protected void btnSend_Click(object sender, EventArgs e)
{

if (lblCaptcha.Text == txtCaptcha.Text)
{

//more code here to process the E-mail form.

}

else

{

//Show error msg

}

that’s it!

Just ran into this site while downloading Subversion for my home source code repository.  Yes, I use source code  control at home…pretty geeky I know. The link below is a list of the Open Source Projects I use as a part of daily computing.
