Contoh Aplikasi Kalkulator dengan visual c#

Silahkan download Link ini....

HeldoCalc.rar

dan extract Password : hilmi

Setelah itu buka saja pake

visual c# 2010

, atau visual studio yang versi lain....

kode nya dibawah ini, ya kalo gak mau ribet alias copy paste, ya silahkan download file diatas, 

good luck !!!!!
