Di jaman sekarang,,, masi hitung pake jari...? cape dehhh

Kalkulator memang sangat berguna untuk mempermudah perhitungan matematika sehingga tidak sampe uban dan botak... tapi kira-kira bagaimana yahh cara membuat software kalkulator ??? jangan khawatir karena kali ini saya akan memberikan tutorial untuk membuat kalkulator sendiri dengan visual basic.net
okkk mari kita mulai...langkah demi langkah

1. membuka visual studio melalui start --->> all program --->> Microsoft visual studio 2008-->> dan microsoft visula studio 2008 lagi. maka akan tampil seperti gambar di bawah
   
2. klik file -->> new project untuk membuat project baru. Tentukan folder tempat penyimpanan hasil kerja dengan klik tombol browse dan beri nama kalkulator pada kolom name.dilanjutkan dengan klik ok.
3. desain form dengan 1 buah textbox dan 16 button seperti gambar di bawah
4. atur properties di bagian text.x, +,-,/, cc, hasil, 1, 2,3 dan seterusnya  untuk semua tombol
   
   sehingga tampilan seperti gambar di bawah
   
5. klik kanan di area form, pilih view code dan ketikan kode program di bawah ini
   atau copy paste alias copas saja biar gampang
