You want it will automatically display on web page or It will display after some event fired on Web page.

Hi everyone,
actually im working on asp.net i have designed a student details page called student.aspx, it has got the student id textbox, student name textbox and other related fields i have the student details table in my sqlserver database. Now on entering the student id it connects to the database and retrieves the details corresponding to the id entered. everything is perfect the only problem that i encountered is when i enter an id that is not present in the database i receive the following command
Invalid operationException was unhandled by user,Invalid attempt to read when no data is present.
I dont want this to happen instead i need to have the msg as "No Record Found" in a Label. how do i handle this error... Do please help me...
Thanx in advance...

HasRows returns a bool to indicate if you have any rows retuned, but it doesn't actually advanced the reader to the next (or first) row. You need to replace the call to HasRows with a call to Read(), which advanced the reader to the next row. Read() will return false if there are no more rows to read.

How could you retrives the data from database, you should check the result set for number of rows,like

sample codes:

for SqlDataReader:

SqlDataReader dr;
if (dr.HasRows == true)
{
//display records
}
else
{
//no records
}

if you are using datatable, dataset etc,use like the below one
DataTable dt;
if (dt.Rows.Count > 0)
{
//records found
}
else
{
//no records
}

How do I read the received emails using ASP .NET?

Place you code inside a try/catch block and test for the number of rows returned first

try<br />
{<br />
  DataTable dt = GetRecords();<br />
  if( dt.rows.count == 0)<br />
    label.Text = "No records found";<br />
  else<br />
   ...<br />
}<br />
catch(Exception ex)<br />
{<br />
  label.Text = ex.message;<br />
}

only two letters away from being an asset

We can send mail using System.Net.Mail namespace in ASP .NET. But do we have any API to read mails via POP server using ASP .NET? Please help as I have not come across any such thing. Will I be able to read every details of the mail i.e. all the headers and the body?

cookies are used to store the values in text files. Basically cookies are text files used to store data in it. So, the user can retrieve the data later from the cookies.

Did that , but now luck,,

And also tried

1. Open RegEdit
2. Browse to HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main
3. Add a dword under this key called TabProcGrowth
4. Set TabProcGrowth to 0
Additional to it you need to do this
1. Open Internet Explorer
2. Go to Tools->Internet Options
3. Switch to the Advanced tab
4. Uncheck 'Disable script debugging (internet explorer)'

But no luck
