C# Q, reading from textboxes to a SQL DB.

Question

Hi folks, first post so here it goes. I am getting an error when I attempt to save data from a selection of textboxes into a SQL server 2005 DB. I am using visual studio 2005, c#. Here is a sample of my code: //Add entered data into Remote Access Table(tblRemoteAccessDetails) protected void btnSaveRemoteAccessDetails_Click(object sender, EventArgs e) { string szSQL; szSQL = string.Format("INSERT INTO tblRemoteAccessDetails (RemoteAccessID, RemoteAccessIP, RemoteAccessmethod, RemoteAccessports, RemoteAccessUsername, RemoteAccesspassword, RemoteAccesscomments) VALUES({0}, {1}, '{1}', {1}, '{1}', '{1}', '{1}'", //Where to define ExecuteSQL? txtNewRemoteAccessID.Text, txtNewRemoteAccessIp.Text, txtNewRemoteAccessMethod.Text, txtNewRemoteAccessPorts.Text, txtNewRemoteAccessUsername.Text, txtNewRemoteAccessPassword.Text, txtNewRemoteAccessComments.Text); connection.ExecuteSQL(szSQL); Now, my question is I am getting the error: Error 109 'System.Data.SqlClient.SqlConnection' does not contain a definition for 'ExecuteSQL' Where do I define this method? In the web.config file? If so any ideas on how to do so, I feel if I get this error sorted I will be close to having my project working. I have tried MSDN help and various books but they are of little help with this error. Thanks for the feedback.
