I'm new to Visual Studio. I'm currently creating a Login form.
I have this code.
string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
try
{
using (OdbcConnection connect = new OdbcConnection(connectionString))
{
connect.Open();
OdbcCommand cmd = new OdbcCommand("SELECT username, password FROM receptionist", connect);
OdbcDataReader reader = cmd.ExecuteReader();
if (username_login.Text == username && password_login.Text == password)
{
this.Hide();
MessageBox.Show("Invalid User", "Login Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
this.Close();
}
else
MessageBox.Show("Invalid User", "Login Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
connect.Close();
}
}
catch (OdbcException ex)
{
MessageBox.Show(ex.Message, "error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
But whenever I try to type in the username and password there is an error called Configuration system failed to initialize. I'm just wondering what kind of problem is this and how could I solve this?
Please help.

Make sure that your config file (web.config if web, or app.config if windows) in your project starts as:
Note that inside the
configuration
element, the first child must be theconfigSections
element.In the
name
property onsection
element, make sure you replaceYourProjectName
with your actual project's name.It happened to me that I created a webservice in a class library project, then I copied (overwriting) the config file (in order to bring the endpoints configuration) to my windows app and I started to have the same problem. I had inadvertently removed
configSections
.it worked for me, hope it helps
