Dasturlash fanidan 1-Mustaqil ishi
Mavzu: Maktab o’quvchilarini baholash tizimini samarali usullarini yaratuvchi dastur yaratish

Ushbu dasturni yaratish uchun biz avvalo C++builder dasturini ochib olamiz va dasturdagi ushbu tugma ustiga bosib
Ushbu oynani hosil qilamiz. So’ng image komponentasining ustiga bosib, strelka turgan joyga bosamiz va image komponentasining Properties bo’limidan Picture hususiyatiga rasm yuklab olamiz. Biz buni quyidagicha amalga oshiramiz.

Load rasm tanlab ochish tugmasi bosiladi ok tugmasi bosiladi Align hususiyatidan Client tanlab olinadi
Stretch hususiyatini true o’zgartiriladi.

Ushbu holatga keladi. Keyin Edit komponentalarini tashlab olamiz va 1 dona Button komponentasini tashlab olamiz.
Ushbu oyna hosil bo’ladi. Keyin Yana bir Forma hosil qilamiz. Biz unga ushbu ketma-ketlikni hosil qilamiz.
ADOConnedtion---ADOTable---DataSource---DBGrid---Panel---BitBtn 3 ta---MainMenu---Label---sSkinManager larni birinma ketin Formaga tashlaymiz.
Ushbu holatga keladi. Bunda ADOConnectionga bazani bog’lab olamiz, ADOTabelni ADOConnectionga bog’laymiz, DataSourceni ADOTablega bog’laymiz, DBGridni DataSourcega bog’laymiz So’ngra biz yana bir Forma ochamiz. Unga 3ta DBEdit --- 3taLabel--- 1ta BitBtn --- Edit kompanentalarini tashlab quyida joylashtiramiz
DBEditlarni DataSourcega bog’lab olamiz. Biz bunda Edit komponentasini Visible hususiyatini true ga o’zgartiramiz.
So’ng biz yana bir Forma tashlab unga quyidagilarni tashlaymiz: 2ta Edit ---2ta Label --- 1ta Button Komponentalarini tashlaymiz

Va Formalarni bir biriga bog’lab olamizda ushbu kodlarni kiritamiz:
Forma 1 uchun:
