Now I want to have automatic number counter  which will be displayed before showing final result like a waiting counter.

Hello Mark Lesliez,

You can integrate with your SQL command to generate automatic numbers just use the "SELECT MAX(Field_Name) as Variable from Table_Name" and add 1 so that it will increase or the increment method. For example:

 

res = stmt->executeQuery("SELECT MAX(Notes) as noteNum FROM Tasks");
while (res->next())
{
 count = int(noteNum)  +  1;
}

I have not checked that in C++ since I don't use C++ anymore (I've used that for 4 years ago). Just use the idea I have given you. I hope that would help you.
