2-LABARATORIYA

1. 
   Ikkinchi bosqichda quydagi oyna ko`rinishini hosil qilamiz (2-rasm). Bu yerda 6 ta label, 2 ta button,2ta TextBox, 2 ta panel va 1 PictureBox kompanentalarida foydalanilgan. Label1ni panel1ga joylashtirib text xossasiga “2-labaratoriya” deb yozdim. Label2ni panel2ga joylashtirib text xossasiga “Salomov Shoxruhning” deb yozdim.Label3ni text xossasiga “A=” deb yozib, TextBox1 ni yoniga joylashtirdim. Label4ni text xossasiga “B=” deb yozib, TextBox2 ni yoniga joylashtirdim. Button1 va Button2 kompanentasining text xossasiga “C=” va “P=” deb yozib,label5 va label6 ni yaqiniga joylashtirdim. Buni ishlatishda Button1 (C=) bossak gipotenuzani hisoblaydi. Button2 (P=)ni bosilsa perimetrni hisoblaydi. PictureBox1 ga tug`ri burchakli uchburchak rasmini quydim.
