How do I set different login paths depending on the user credentials provided.

[Indra99]

Hi , I have a Login page and want that if the user credentials provided are those of the Administrator(Username = Administrator) then a Window Form App Page called "AdminPage" should open up. Else another Window Form App called "Main_Page" should open up.

What I have tried:

try
{
SqlConnection cn = new SqlConnection("Data Source=PV10\\LOCALSERVER;Initial Catalog=SmallSoftwareDB;Integrated Security=True;Pooling=False");
SqlCommand cmd = new SqlCommand("select * from UserCredentials where Username='" + textBox1.Text + "' and Password='" + textBox2.Text + "'", cn);
SqlDataReader dr;
cn.Open();
dr = cmd.ExecuteReader();
int cnt = 0;
while (dr.Read())
{
cnt++;
}
if (cnt == 1)
{
MessageBox.Show("Successful Login...", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
string query = "select Username, Password from UserCredentials where Username='Administrator";
SqlCommand cmdA = new SqlCommand(query, cn);
dr = cmdA.ExecuteReader();
int k = 0;
while (dr.Read())
{
k++;
}
if (k == 1)
{
AdminPage A_P = new AdminPage();
A_P.Tag = this;
A_P.Show(this);
Hide();
}
Main_Page Mp = new Main_Page();
Mp.Tag = this;
Mp.Show(this);
Hide();
cn.Close();
textBox1.Clear();
textBox2.Clear();
}
else
{
MessageBox.Show("Invalid UserName or Password", "Message", MessageBoxButtons.RetryCancel, MessageBoxIcon.Warning);
textBox1.Clear();
textBox2.Clear();
}
}
catch (Exception err)
{
MessageBox.Show(err.Message, " ", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
