TUGAS 2 PBKK C - Membuat Sistem Application Dengan .NET Framework
1. Instalasi Visual Studio Enterprise 2019
Pertama anda harus install visual studio dulu. Setelah sudah didownload, maka install visual studio tersebut dan centang workloads ASP.NET and web development (untuk membuat website) dan .NET desktop development (untuk membuat aplikasi desktop).
Perlu diingat bahwa anda bisa menginstall workloads sesuai kebutuhan anda, jadi tidak harus semua diinstall.
2. Hello World
Pilih file -> new project, lalu pilih Consol App (.NET Framework), lalu klik next.
Setelah itu beri nama project, lalu klik create. Setelah itu ketikkan kode seperti dibawah ini.
Jika sudah, klik start atau tekan ctrl + F5 di keyboard, maka akan keluar outputnya seperti gambar dibawah ini.
3. Kalkulator Sederhana
Buat project baru dengan Windows Forms App (.NET Framework) dengan bahasa Visual Basic. Bisa juga yang versi bahasa C#, tetapi disini saya menggunakan Visual Basic. Lalu klik next, beri nama project, lalu create.
Setelah itu akan muncul tampilan form kosong, lalu modifikasi form tersebut menyerupai kalkulator seperti diatas. Caranya adalah drag n drop dari toolbox dan ganti namanya di properties. Jika sudah, klik kanan formnya lalu view code, lalu isikan code seperti dibawah ini :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 | Public Class Calculator Dim firstnumber As Integer Dim secondnumber As Integer Dim answer As Integer Dim aritmathicproccess As String Private Sub btn1_Click(sender As Object, e As EventArgs) Handles btn1.Click txtText.Text = txtText.Text & 1 End Sub Private Sub btn2_Click(sender As Object, e As EventArgs) Handles btn2.Click txtText.Text = txtText.Text & 2 End Sub Private Sub btn3_Click(sender As Object, e As EventArgs) Handles btn3.Click txtText.Text = txtText.Text & 3 End Sub Private Sub btn4_Click(sender As Object, e As EventArgs) Handles btn4.Click txtText.Text = txtText.Text & 4 End Sub Private Sub btn5_Click(sender As Object, e As EventArgs) Handles btn5.Click txtText.Text = txtText.Text & 5 End Sub Private Sub btn6_Click(sender As Object, e As EventArgs) Handles btn6.Click txtText.Text = txtText.Text & 6 End Sub Private Sub btn7_Click(sender As Object, e As EventArgs) Handles btn7.Click txtText.Text = txtText.Text & 7 End Sub Private Sub btn8_Click(sender As Object, e As EventArgs) Handles btn8.Click txtText.Text = txtText.Text & 8 End Sub Private Sub btn9_Click(sender As Object, e As EventArgs) Handles btn9.Click txtText.Text = txtText.Text & 9 End Sub Private Sub btn0_Click(sender As Object, e As EventArgs) Handles btn0.Click txtText.Text = txtText.Text & 0 End Sub Private Sub btnPlus_Click(sender As Object, e As EventArgs) Handles btnPlus.Click firstnumber = Val(txtText.Text) txtText.Text = "" aritmathicproccess = "+" End Sub Private Sub btnMinus_Click(sender As Object, e As EventArgs) Handles btnMinus.Click firstnumber = Val(txtText.Text) txtText.Text = "" aritmathicproccess = "-" End Sub Private Sub btnTimes_Click(sender As Object, e As EventArgs) Handles btnTimes.Click firstnumber = Val(txtText.Text) txtText.Text = "" aritmathicproccess = "x" End Sub Private Sub btnBagi_Click(sender As Object, e As EventArgs) Handles btnBagi.Click firstnumber = Val(txtText.Text) txtText.Text = "" aritmathicproccess = "/" End Sub Private Sub btnResult_Click(sender As Object, e As EventArgs) Handles btnResult.Click secondnumber = Val(txtText.Text) If aritmathicproccess = "+" Then answer = firstnumber + secondnumber End If If aritmathicproccess = "-" Then answer = firstnumber - secondnumber End If If aritmathicproccess = "*" Then answer = firstnumber * secondnumber End If If aritmathicproccess = "/" Then answer = firstnumber / secondnumber End If txtText.Text = answer End Sub Private Sub btnCE_Click(sender As Object, e As EventArgs) Handles btnCE.Click txtText.Text = "" End Sub End Class |
