I have a button to save some process in my APPayments Form.
In this Form i have a Button to generate an XML and set the Payment as "Generated".
When click the button, the process run and set the values.
But... I need a confirmation message on this button:
Ok: run the process normal
Cancel: this option cancel the process to set the "Generated" value
How can i set a confirmation message?
I code in Visual Basic.
Sorry for my english
