Answer 1

The better is you directly ask a specific question to let a maximum of people answer you.
If you are too global, nobody will help you.

Answer 2

I have created a user interface in which the name and increment date of a person....... What is the necessary condition so that when I enter someone's name it appears to me in a result when I press OK (hello + the name entered) and when the user enters numbers, a symbol or a formed word From numbers and letters together, and when I press the OK button, it clears the entrance, the result appears. Re-enter a name....... In the second line for calculating the age, I want when I enter the date of birth, for example 1999. When I click on OK2, the person’s age is 23 years, for example.
