What is the question ? You can disable the button after first click.

You have to retrive Max no present in database after that increment it by one or if DataBase is empty assign it 1.

Code similar to the one below will do it for you

C#

.....

public class Form1()
{
     private bool incremented;
     private int numToIncrement;

........


     public Form1()
     {
          numToIncrement=0;
          incremented = false;
     }

     private void button1_Click(.......)
     {
           numToIncrement = //Get number from database here
          if(!incremented)
          {
              numToIncrement++;
              // put code her to show a messagebox to indicate that the number 
              //has already been incremented or whatever other way you want to 
              //do it
              //save to database here

          }
          else
          {
              
                // put code her to show a messagebox to indicate that the number 
                //has already been incremented or whatever other way you want to 
                //do it
          }

          incremented = true;

     }

     ........
}

it should check for the previous number from database and it should generate with respect to dat value

Update the code. You really could have figured that part out yourself
