1.Yangi ilova yaratamiz.

2.Formaga Standart komponentalar palitrasidan ComboBox komponentasini ComboBox1 nom bilan, Memo komponentasini Memo1 nom bilan va ikkita Botton1 va Botton2 tugmalarini o’rnatamiz.

3.Oldingi misol kabi bu komponentalarning xossalarini ham o’rnatamiz va dastur kodlarini ham kiritamiz. Hamma dastur kodlari “kiritish” tugmasiga boғliq, ya’ni Botton1 moduli kodlari quyidagicha bo’ladi.
