[readnlearn]

hii i hav a problem with thsi code
check it once

if (!this.IsPostBack)
 
// Create a random code and store it in the Session object.
 
this.Session["CaptchaImageText"] = GenerateRandomCode();
 
else
 
{
 
// On a postback, check the user input.
 
if (this.CodeNumberTextBox.Text ==
 
this.Session["CaptchaImageText"].ToString())
 
{
 
// Display an informational message.
 
this.MessageLabel.CssClass = "info";
 
this.MessageLabel.Text = "Correct!";
 
}
 
else
 
{
 
//Display an error message.
 
this.MessageLabel.CssClass = "error";
 
this.MessageLabel.Text = "ERROR: Incorrect, try again.";
 
// Clear the input and create a new random code.
 
this.CodeNumberTextBox.Text = "";
 
this.Session["CaptchaImageText"] = GenerateRandomCode();
 
}
 
}
 
}

the second else is directly executing without anywrong entry of text
so please tell how to correct thsi code

Suggest using try catch to debug errors...

Try inserting a break point on the second if statement to make sure that the values are what they should be, it would appear to me that one of those values gets an unexpected value and thus the 2 are never equal
