Answer 1

You have a typo

RegistraionNo instead of RegistrationNo

in

string SelectStatement = "SELECT * FROM MyTable where RegistrationNo = '@RegistraionNo'";

another in

textBox3.Text = reader["RegistratioNo"].ToString();

You’ll copy 100 lines of

I want a registration, I want a registration, I want a registration.
