Praktikum ASP 4

kalau di Praktikum ASP 3 kita masih menggunakan Console Application,, kali ini di Praktikum ASP 4 kita bakalan menggunakan Windows Forms Application, dan bermain-main dengan Form. Nah ini langkah-langkah pembuatan progamnya :

• Dengan menggunakan software Visual Studio Ultimate 2012, buka New Project
•  Pilih Visual C# -> Windows -> Windows Form Application
• Beri Nama Project/Solution Name -> ASP04 (isikan bebas)

• Klik OK

•  Kemudian masukkan Tool - tool berikut : Seperti Label, Button, ErrorProvider, ProgessBar, TextBox
• Kemudian Susun hingga seperti gambar :
  
• Kemudian Masuk ke Form1.cs, ketikkan Script berikut :
  using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  using System.Windows.Forms;
  
  namespace FormVal
  {
      public partial class Form1 : Form
      {
          public Form1()
          {
              InitializeComponent();
          }
  
        
  
          private void Form1_Load(object sender, EventArgs e)
          {
          }
  
          private void button2_Click(object sender, EventArgs e)
          {
              bar1.Value = 0;
  
  
              if (a.Text == "")
              {
                  x.SetError(a, "Nama");
              }
              else
              {
                  x.SetError(a, "");
              }
  
              if (b.Text == "")
              {
                  x1.SetError(b, "Nama");
              }
              else
              {
                  x1.SetError(b, "");
              }
  
              if (c.Text == "")
              {
                  x2.SetError(c, "Nama");
              }
              else
              {
                  x2.SetError(c, "");
              }
  
              if (d.Text == "")
              {
                  x3.SetError(d, "Nama");
              }
              else
              {
                  x3.SetError(d, "");
              }
  
              if (a.Text == "" )
              {
                  x.SetError(a, "Masukan nama");
                  MessageBox.Show("Data kurang Lengkap, Lengkapi namamu!");
                  for (int i = 0; i < bar1.Maximum; i++)
                  {
                      bar1.Value = bar1.Value + 1;
                  }
  
  
              }
              else
              {
                  if (b.Text == "")
                  {
                      x1.SetError(b, "Masukan NIS");
                      MessageBox.Show("Data kurang Lengkap, Lengkapi NIS!");
                      for (int i = 0; i < bar1.Maximum; i++)
                      {
                          bar1.Value = bar1.Value + 1;
                      }
                  }
                  else
                  {
                      if (c.Text == "")
                      {
                          x2.SetError(c, "Masukan Kelas");
                          MessageBox.Show("Data kurang Lengkap, Lengkapi Kelas!");
                          for (int i = 0; i < bar1.Maximum; i++)
                          {
                              bar1.Value = bar1.Value + 1;
                          }
                      }
                      else
                      {
                          if (d.Text == "")
                          {
                              x3.SetError(d, "Masukkan SMP");
                              MessageBox.Show("Data kurang Lengkap, Lengkapi Asal SMP");
                              for (int i = 0; i < bar1.Maximum; i++)
                              {
                                  bar1.Value = bar1.Value + 1;
                              }
                          }
                      }
                    
                  }
  
              }
                   
              if (d.Text != "" && a.Text !="" && c.Text !="" && b.Text !="")
              {
                  for (int i = 0; i < bar1.Maximum; i++)
                  {
                      bar1.Value = bar1.Value + 1;
                  }
                  MessageBox.Show("\nNama\t : " + a.Text + "\nNIS\t : " + b.Text + "\nKelas\t : " + c.Text + "\nAsal SMP\t : " + d.Text);
              }
          }
  
     
  
          private void b_KeyPress(object sender, KeyPressEventArgs e)
          {
              const char Delete = (char)8;
              e.Handled = !Char.IsDigit(e.KeyChar) && e.KeyChar != Delete;
          }
  
          private void button1_Click_1(object sender, EventArgs e)
          {
              a.ResetText();
              b.ResetText();
              c.ResetText();
              d.ResetText();
              bar1.Value = 0;
              x.SetError(a, "");
              x1.SetError(b, "");
              x2.SetError(c, "");
              x3.SetError(d, "");
          }
  
          private void a_TextChanged(object sender, EventArgs e)
          {
  
          }
      }
  }
• Setelah itu coba tekan CTRL + F5
• Maka hasilnya akan seperti ini :
  
• Selamat Mencoba dan Selamat Bereksperimen sendiri :D Semoga Berhasil.. :P
