Dasturlash II fanidan

2 – Dedline topshirig’i

Bajardi : Xalimjonov Abdulahad
Qabul qildi: Xolmatov Abrorjon
2 - Dedline
Mavzu: C++ Builder dasturida kontaklar dasturini yaratish

Avval yangi proyetk yaratib, save all orqali saqlab olamiz. Keyin taxminiy o’lchamlarni olib, bloknotga o’xshatib olamiz. Form1 oynasini captioniga o’zimiz hohlagan nomni yozamiz, Bloknot. BorderIcons funksiyasidan biMaximizeni false qilib qo’yamiz. Position funksiyasini esa poScreenCenter qilib qo’yamiz. Formani rangini Color xususiyatidan clWhite qilamiz. Undan keyin esa Tool Palette dan 2ta panel, statictext, speedbuttonlarni tartib bilan Formaga tashlab olamiz. Panelni Captionini o’chirib yuboramiz.
