How can I know when the value of a field in a form has been changed? in General Posted July 19, 2019 Hiello Sherzod Forgive me for taking time to respond. Unfortunately for some diabetic problems I have been inactive. As I commented in my initial message, I am a newbie with UniGui. I'm sorry but I do not have the information you ask me. I have looked in the documentation that I have on hand about the code that I am modifying and I have not found it. The application that I have been asked to modify was already installed and I only have access to the source code. I am going to ask those who have asked me to modify this application if they can provide me with that information. As soon as I get that information, I'll share it with you. Thank you very much for your help.
