The compiler is worried about you possibly storing that pointer to a date which in that context is a temporary. You aren't but the correct way to fix this in C++ is to pass date as a const reference parameter. You get the speed of a pointer, but much safer code.

I'd like to know why there is the change and how to fix it properly though. An example of a rogue lines is this: queryString += "\"" + sqlFormatString(&ui->dateInDateEdit->date()) + "\","; The routine is defined as follows: QString enter_invoice_in::sqlFormatString(QDate *date); So, I'm passing a pointer to a date which is on a form. Thanks again.
