Dear Friend ,
I have created the login page, you just go through the code of that page below:

{
lblerrormsg.Text = "";
txtuname.Text = "";
passwrd.Text = "";
txtuname.Focus();
}
}
Now the thing I have created a database table in SQL which can store userlogins now I want to know how to write the code in c# which can verify userlogins how to pass the parameters to compare user logins.
Thanks

I think youre a genuine beginner at this stage. What you need to do here is to access the database from ur application and in this code sample here there is no sign of any DataAdapter or a query used.
First get some knowledge abt the DataSets, TableAdapters, ADO .NET and DataAdapters,
you could do it like this.
string sql =@"Select UserName From UsersTable Where UserName LIKE '"+textBoxUserName.Text+"' AND Password = '"+textBoxpass.Text+"';
//(Caution: password is case insensitive in this case. Convert it to Varbinary for making it case sensitve)
SqlCommand cmd = new SqlCommand(sql, sqlConnection1);
if(cmd.ExecuteNonQuery() == 1)
{
// login successful
}
else
{
login failed
}
Its always a better idea not to store the actual text for passwords in Db. Its better to use an encoding scheme. But for now, u have a long road ahead of u

Thanks for your help I will try.
Bye!

Dearfriend I changed the coding as u told me...
plz make the correction of the below code..
protected void Button2_Click(object sender, EventArgs e)
{
string sql =@"Select [Username],[Password] From [Login] Where UserName = '"+Textbox1.Text+"' AND Password ='"+Textbox2.Text+"'";
SqlConnection con = new SqlConnection("Data Source=BILAL\\SQLEXPRESS;Initial Catalog=Customers;Integrated Security=True");
SqlCommand cmd = new SqlCommand(sql, con);
//cmd.Parameters.AddWithValue("@Username", Textbox1.Text);
//cmd.Parameters.AddWithValue("@Password", Textbox2.Text);
con.Open();
//cmd.ExecuteNonQuery();
if(cmd.ExecuteNonQuery()==0)
{
// login successful
Response.Redirect("Mainmenu.aspx", false);
}
else
{
lblerrormsg.Text = "Invalid Login";
//Button2.Attributes.Add("onclick", "return validations();");
Textbox1.Text = "";
Textbox2.Text = "";
Textbox1.Focus();
}
con.Close();
}
I have done Insertion Deletion Updation but I am not able to create the logic for to compare the input with a sql table , please modify the coding completely
thank You.
With Regards
Bilal

Hi.
I'm writing an application able to work with Access, MS SQL Server 2005 or MySql database, depending on the user's will.
I want to use the classes of the System.Data.OleDb namespace for all three providers.
It's working with Access so for and now I'm trying to use the other two.
What connection strings must be specified for MySql and MS SQL 2005?
(Remote connection must be possible).
Thanks.

Why? This will be inefficient when there are native drivers available. Why not take a look at the Factory pattern that MS used with .NET 2? This allows you to work in a reasonably database agnostic fashion. Take a look at the classes DbConnection and DbCommand in System.Data.Common to get an idea as to how it all works.
Deja View - the feeling that you've seen this post before.

Also, look up dataprovider factory on msdn. This will give you some good info.

Hi,
I am getting the exception " Procedure or function SummerizeInsert has too many arguments specified." But so far my coding is correct. also i noticed this error comes when the loop is going through for the second time.

It appears your insert command exists prior to the loop. The loop adds the necessary parameters. On the second iteration it adds the parameters again to the command. So there are now two sets of parameters in the command. (Hence the too many parameters exception)
You need to either
* setup the parameters once (before the loop) and assign the values only on each loop.
Or
* remove all the parameters in the command at the start of the loop.

It seems, the connection is not closed, so you are passing into stored procedure
number of ther required parameters multpileid by number of rows in your DataTable.
I am not sure, this was your intend

AS THE ERROR INDICATES YOU HAVE PASSED MORE VALUES TO THE PROCEDURE/FUNCTION THAN REQUIRED.

You may wish to fix your caps lock key - it appears to be broken.

if you can see i have have have the exact number of parameters sent as required.

This means, you haven't closed the connection to your db server. So, you are passing the parameters twice!

from flexi_pump
order by tag asc
) as newtbl order by tag desc
) as newtbl2 order by tag asc
it works great, but what if the last page only has one row. this sql query shows the last four, not only the last one. (my table has 9 rows)
