Regarding to not calling of enquiry.cs in app code - asp.net

Question

I am a newcomer in .net , my problem is related to email. This code is well performed on my localhost. This is code of my enquiry.aspx.cs:-
protected void Button1_Click(object sender, EventArgs e)
{
Mail mm = new Mail();
if (DropDownList3.SelectedItem.Text == "--Select--")
{
Label5.Text = "Please Select Course";
//Page.ClientScript.RegisterStartupScript(this.GetType(), "Error", "alert('Please Enter Name');", true);
//Response.Write("<script language=JavaScript> alert('Please Enter Name'); </script>");
}
else if (TextBox1.Text == "")
{
Label5.Text = "Please Enter Name";
//Page.ClientScript.RegisterStartupScript(this.GetType(), "Error", "alert('Please Enter Name');", true);
//Response.Write("<script language=JavaScript> alert('Please Enter Name'); </script>");
TextBox1.Focus();
}
else if (mm.checkValidemail(TextBox2.Text) == false)
{
Label5.Text = "Please Enter E-Mail ID";
//Page.ClientScript.RegisterStartupScript(this.GetType(), "Error", "alert('Please Enter E-Mail ID');", true);
//Response.Write("<script language=JavaScript> alert('Please Enter E-Mail ID'); </script>");
TextBox2.Focus();
}
else if (mm.checkValidmobile(TextBox3.Text) == false)
{
Label5.Text = "Please Enter Mobile Number";
//Page.ClientScript.RegisterStartupScript(this.GetType(), "Error", "alert('Please Enter Mobile Number');", true);
//Response.Write("<script language=JavaScript> alert('Please Enter Mobile Number'); </script>");
TextBox3.Focus();
}
else
{
myenquiry ee = new myenquiry();
//myenquiry ee=new myenquiry();
int i = ee.add_enquiry(TextBox1.Text, TextBox2.Text, TextBox3.Text, TextBox4.Text, TextBox5.Text, "-", "-", "NORMAL ENQUIRY FROM SITE", TextBox11.Text, DropDownList3.SelectedItem.Text, TextBox12.Text,locationlst.SelectedItem.Text);
if (i == 1)
{
MailMessage message = new MailMessage();
message.From = new MailAddress(" Enquiry " + "<shila#gmail.com> ");
message.To.Add(new MailAddress("shu#gmail.com"));
message.CC.Add(new MailAddress("va_aone#yahoo.com"));
message.Subject = "Enquiry from CMC site";
string p = "<b>Name: </b>" + TextBox1.Text;
p += "<br><b>Mobile:</b> " + TextBox3.Text;
p += "<br><b>Mail ID:</b> " + TextBox2.Text;
p += "<br><b>Address:</b> " + TextBox4.Text;
p += "<br><b>City:</b> " + TextBox5.Text;
p += "<br><b>Location:</b>" + locationlst.SelectedItem.Text;
p += "<br><b>College:</b> " + TextBox11.Text;
p += "<br><b>Course:</b> " + DropDownList3.SelectedItem.Text;
p += "<br><b>Query:</b> " + TextBox12.Text;
message.Body = p;
message.IsBodyHtml = true;
SmtpClient SMTPServer = new SmtpClient("localhost");
try
{
SMTPServer.Send(message);
//result = "Your Enquiry has been Submitted !!";
Label5.Text = "Your Enquiry has been Submitted !!";
//Response.Write("<script language=JavaScript> alert('Your Enquiry has been Submitted !!'); </script>");
TextBox1.Text = "";
TextBox2.Text = "";
TextBox3.Text = "";
TextBox4.Text = "";
TextBox5.Text = "";
TextBox11.Text = "";
TextBox12.Text = "";
DropDownList3.SelectedIndex = 0;
}
catch
{
Label5.Text = "Server Problem !!Your Enquiry Not Submitted";
//Response.Write("<script language=JavaScript> alert('Server Problem !!Your Enquiry Not Submitted'); </script>");
}
}
else
{
Label5.Text = "Server Problem !!Your Enquiry Not Submitted";
}
}
and this is my appcode folder enquiry.cs:-
public class myenquiry
{
SqlConnection conn = new SqlConnection("Data Source=USER-PC;Initial Catalog=group;Integrated Security=True");
SqlCommand comm = new SqlCommand();
int result = 0;
public int add_enquiry(string nam,string email,string mob,string adr,string cit,string state,string country,string zip,string college,string tech,string query,string loc)
{
try
{
comm.Connection = conn;
comm.CommandText = "insert into enquiry(name,email,mobile,address,city,state,country,zip,college,technology,query,edate,location) values('" + nam + "','" + email + "','" + mob + "','" + adr + "','" + cit + "','" + state + "','" + country + "','" + zip + "','" + college + "','" + tech + "','" + query + "','" + DateTime.Now.ToString("yyyy-MM-dd") + "','"+loc+"')";
conn.Open();
comm.ExecuteNonQuery();
result = 1;
}
catch(Exception ee)
{
result = 0;
}
finally
{
conn.Close();
}
return result;
}
}
this is well perform on local. But at the server the appcode enquiry.cs is not called on enquiry.aspx.cs and the value of int i is becoming 0, so the else part is executing. Why?

Answer 1

You seem to have a hard coded connection string in the myenquiry class. If you are not dynamically setting the connection string from a configuration file or otherwise, the insert method will try to use that string which points to your local. Assuming your server is a different domain/machine with no access to your local DB, the connection will definitely fail, giving you the result 0.

Answer 2

As Shree.pat18 says Don't make hardcodded connection string in class file.instead of this make your connection string in web.config file something like this in your configuration tag
<connectionStrings>
<add name="cn" connectionString="Data Source=USER-PC;Initial Catalog=group;Integrated Security=True"/>
</connectionStrings>
