Analis Program Visual Basic

Jawaban Latihan 1 NO.3


a.  Penyebabkan error pada btalamat1_Click adalah :

Kita seharusnya mendeklarasikan variabel “alamat” dengan DIM dan type data STRING

        Dim alamat As String

        alamat = "kuningan"

        txtalamat.Text = alamat

b.         Karena Pada tombol nama1 pendeklarasian nama sudah di masukan Dim nama As String

Nama = “Nandang” dan pada tombol nama2, nama belum di deklarasikan sehingga sehingga mengambil dari module

Pada Btalamat 1 dan tombol alamat

2 sudah di deklarasikan di form

1 dengan Conts alamat = “kuningan”

 

c. Analisa saya untuk Form Dua, saat kita melihat coding pada FrmDua kita melihat ada baris perintah :
Option Explicit Off
Itu artinya bahwa variabel pada FrmDua tidak perlu kita definisikan dan program akan langsung mengambil definisi variabel-variabel itu dari variabel Public yang terdapat dimanapun. Pada program ini variabel-variable tersebtu terdapat pada Module1. Sehingga pada saat kita menekan tombol Nama atau Alamat atau Umur, nilai yang keluar adalah nilai yang terdapat pada Module1.

 

 

 

Latihan 2

 

Kelemahan

 

Kelemahan dari program ke dua yaitu tidak ada deklerasian dari “TAS”, sehingga jika kita ingin memunculkan harga tas tidak bisa. Cara memperbaikinya dengan mendambahkan variabel Tas.
Contoh program : Case “TAS”
namabarang = “TAS”
harga =200000

 

Case Else

                namabarang = "TAS"

                harga = 200000

selamat mencoba

MEMBUAT APLIKASI SUHU DENGAN VISUAL BASIC

• Pada Button1(Kelvin)

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim x, z As Double

x = Val(TextBox1.Text)

z = x + 273

TextBox2.Text = z

End Sub

• Pada Button2(Farenheit)

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim x, z As Double

x = Val(TextBox1.Text)

z = (x * 1.8) + 32

TextBox2.Text = z

End Sub

• Pada Button3(Reamur)

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Dim x, z As Double

x = Val(TextBox1.Text)

z = 5 / 4 * x

TextBox2.Text = z

End Sub

• Pada Button4(Hapus)

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

TextBox1.Text = ""

TextBox2.Text = ""
