Praktikum 2

 
Jawaban Latihan 1
 a. Penyebabnya adalah pada alamat = kuningan tidak menemukan target yang jelas, untuk dapat  diketahui/ terbaca oleh program, pada alamat = “Kuningan” di tambahkan tanda ‘ (petik) agar dapat di jalankan.
b. Karena pada nama1 dan nama2  tujuannya berbeda dan pada nama1 menggunakan perintah Dim nama As String, sedangkan di Const alamat1 dan alamat2 tujuannya sama.
c. Karena pada tambah umur 1 menggunakan perintah Dim umur As Integer, sedangkan tambah umur 2 menggunakan perintah Static umur As Integer, dimana Static adalah perintah untuk menaikkan angka/ menambahkan angka pada umur tersebut.
d. Analisa tentang form 2 adalah pada tombol nama, alamat, umur sudah terisi dan ketika di jalankan akan muncul pada nama : Nandang Hermanto, alamat : Purwokerto, umur : 17
     dapat terisi seperti di atas karena pada Module1 sudah tertera sebagai berikut :
     Public Const nama As String = “Nandang Hermanto”
     Public Const alamat As String
     Public umur As Integer

Jawaban Latihan 2

Analisa kelemahan program pada latihan 2 If dan Case adalah ketika memilih barang berupa TAS, nama barang dan harga tidak muncul.
Perbaikannya yaitu pada combo box ditambahkan : Case “TAS”
                                                                           Namabarang = “Tas”
                                                                           Harga = 125000
