Membuat Program Sederhana Menggunakan Visual Studio (Aplikasi Penjualan Sepatu)

Microsoft Visual Studio merupakan sebuah perangkat lunak lengkap (suite) yang dapat digunakan untuk melakukan pengembangan aplikasi, baik itu aplikasi bisnis, aplikasi personal, ataupun komponen aplikasinya, dalam bentuk aplikasi console, aplikasi Windows, ataupun aplikasi web. Aplikasi penjualan sepatu ini dibuat dan dirancang untuk memudahkan/mengefisienkan user dalam menjalani pekerjaan, aplikasi ini didesign khusus sesuai kebutuhan user. Terdapat beberapa menu pada aplikasi ini sebagai berikut :

1. Tampilan Utama

Pada tampilan menu utama terdapat tombol Show Collections, Buy Now dan Exit.

            a. Show collections

Pada tampilan awal terdapat tombol show collection, tombol ini dibuat menggunakan button > Private Sub Button1_Click_1(sender As Object, e As EventArgs) Handles Button1.Click

        ShowImage.Visible = True

         b. Buy now

Sama dengan show collection tombol Buy Now ini menggunakan button > Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click

        Aritmatika.Visible = True

        Me.Visible = False

    End Sub

    

b. Exit

Pada tombol exit > Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

        Me.Close()

    End Sub

2. Form Show image

            Pada menu ini terdapat tombol radio button yang berfungsi untuk memilih jenis sepatu, selain tombol radio button terdapat pula menu Back, Buy dan Exit.

a.   Radio button

digunakan untuk pemilihan gambar sepatu. Terdapat 5 item sepatu pada aplikasi. Radio button > Private Sub RadioButton1_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton1.CheckedChanged

PictureBox2.Image = System.Drawing.Image.FromFile("D:\backup\data kuliah\SMESTER.4\Program2\pictUTS\1.jpg")

 

End Sub

        Private Sub RadioButton2_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton2.CheckedChanged

  PictureBox2.Image = System.Drawing.Image.FromFile("D:\backup\data kuliah\SMESTER.4\Program2\pictUTS\2.jpg")

 

        End Sub

    Private Sub RadioButton3_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton3.CheckedChanged

PictureBox2.Image = System.Drawing.Image.FromFile("D:\backup\data kuliah\SMESTER.4\Program2\pictUTS\3.jpg")

End Sub

    Private Sub RadioButton4_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton4.CheckedChanged

PictureBox2.Image = System.Drawing.Image.FromFile("D:\backup\data kuliah\SMESTER.4\Program2\pictUTS\4.jpg")

    End Sub

    Private Sub RadioButton5_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton5.CheckedChanged

PictureBox2.Image = System.Drawing.Image.FromFile("D:\backup\data kuliah\SMESTER.4\Program2\pictUTS\5.jpg")

    End Sub

b.   Back

Tombol ini dibuat menggunakan Button > Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click

        Me.Visible = False

        Form1.Visible = True

c.   Exit

Pada tombol exit > Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

        Me.Close()

    End Sub

Pada tombol exit > Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

        Me.Close()

    End Sub

3.  Form Buy Now
