Hi,

I have a small method that pulls the largest number out of a Column that is in a table.  It then displays it in a couple of text boxes.

The code works good, but in testing I want a decimal number (xx.x) but only getting an integer right now.

Here is the complete Method:


using (MySqlCommand cmd = new MySqlCommand("SELECT MAX(TDNumber) FROM bbb.traveldocuments", con1))
            {

                con1.Open();

                object result = cmd.ExecuteScalar();
                result = (result == DBNull.Value) ? null : result;
                decimal blah = Convert.ToDecimal(result);
                MessageBox.Show(blah.ToString());   // something to show me what the value of blah is at this point
                txtBox_TD_MAX_NUMBER.Text = blah.ToString();
               
                con1.Close();

                decimal newtd = blah + 1;
                txtBox_TD_nextTDNumber.Text = newtd.ToString();


            }

It's a little complex since my original code was crashing if the value was null (empty database).  Now I get a zero, which isn't bad, just wondering if it's because my Database is empty and the 0 is actually a null?

The format of the Column is 10.1 decimal unsigned.

Thanks!
