problem when iserting in table

I'm building a form that collects some info from the user (user name, password and type ) and I need to store this info into a table called USER that I created.

I'm using 3 text boxes and a button, when the user clicks the button I need to collect this info and store it into my table

when i click the button i get an error msg in this line (comm.ExecuteNonQuery(); )

what do i need to do?

here is the code

protectedvoid Button1_Click(object sender,EventArgs e)

{

string str ="data source=(local);initial catalog=NH_Project1;integrated security=true;";

SqlConnection conn =newSqlConnection(str);

int rows;

SqlCommand comm =newSqlCommand("INSERT INTO [USER](UserId, UserName, UserPassword, Type)VALUES" +

"@.UsrName,@.UsrPass,@.UsrType", conn);

comm.CommandType =CommandType.Text;

comm.Parameters.AddWithValue("@.UsrName",TextBox1.Text);

comm.Parameters.AddWithValue("@.UsrPass",TextBox2.Text);

comm.Parameters.AddWithValue("@.UsrType", TextBox3.Text);

conn.Open();

rows= comm.ExecuteNonQuery();

conn.Close();

louayazar:

comm.Parameters.AddWithValue("@.UsrName",TextBox1.Text);comm.Parameters.AddWithValue("@.UsrPass",TextBox2.Text);

comm.Parameters.AddWithValue("@.UsrType", TextBox3.Text);

Remove the "@." symbol from your AddWithValue calls. Also, I'd recommend enclosing your ExecuteNonQuery call within a Try/Catch block so you can capture any errors in the future.

Hii

I tried to remove the "@." like what you said but that doesn't work, I still have the same error MSG when clicking the button.

Then make sure to put your ExecuteNonQuery call into a Try/Catch block and see what exception you get. This should help you find out what's going on.

that was helpful, thanks a bunch
