Login System (ASP.NET C#) - dreamcon - 06-05-2010 04:49 PM
i have been trying to create a login system for a small project. The username and password are stored in MS SQL i can log in but the session will remain as not logged in any ideas why guys ?
protected void BtnSubmit_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
SqlCommand command = new SqlCommand("SELECT * FROM Member WHERE MemberUsername = @Username AND MemberPassword = @Password", c.connection);
c.connection.Open();
command.Parameters.AddWithValue("@Username", TxtUsername.Text);
command.Parameters.AddWithValue("@Password", TxtPassword.Text);
SqlDataReader DataReader = command.ExecuteReader();
while (DataReader.Read())
{
if (DataReader["MemberRoleID"].ToString() == "1")
{
Session["userid"] = TxtUsername.Text;
LblWelcome.Text = "Welcome: " + (Session["userid"]);
Response.Redirect("Register.aspx");
BtnSubmit.Enabled = false;
}
else if (DataReader["MemberRoleID"].ToString() == "2")
{
Session["userid"] = TxtUsername.Text;
LblWelcome.Text = "Welcome: " + (Session["userid"]);
Response.Redirect("PostComments.aspx");
BtnSubmit.Enabled = false;
}
}
c.connection.Close();
}
}

Your codes look like in ASP.NET 2.0.
Firstly, please put your pages which need be secured into a folder "secured"(any names are available). And just login.aspx is staying at root path(out side of folder "secured").
Thus you can configure the web.config:
<system.web>
<roleManager enabled="true" />
<authentication mode="Forms">
<forms name=".ASPXUSERDEMO" loginUrl="login.aspx" protection="All" timeout="60"/> According to the roleManager configuration as below, any anonymous users will turn back to login.aspx

This is just a small demonstration to show how easy one can "port" the code from my previous tutorials ( Updated: Simple ASP.Net Login Page & ASP.Net Login Page with SQL & ASP.Net Registration Page) over to another programming language in the .NET environment. In this example I chose to use C#.
So for all considerations this tutorial is an exact duplicate of the Updated: Simple ASP.NET Login Page using VB.NET that I did previously, but using SQL instead of Access for the DB
1. Create a Login Webform (HTML/ASP.NET)
- Include any control validation you feel necessary.
