Sebelumnya, kita sudah membahas bagaimana cara membuat notepad sederhana dengan C#. Pada tahap pertama adalah membuat desain formnya.
Pada postingan kali ini, saya akan membahas tahap kedua yang merupakan tahap terpenting yaitu codingan..
Deklarasi :
string namaFile = "";
Dimulai dengan script untuk membuat file baru (Menu-New) :
textBox1.Clear();
namaFile = "";
Menu-File-Open :
openFileDialog1.Filter = "namaFile(*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog1.FilterIndex = 2;
openFileDialog1.ShowDialog();
namaFile = openFileDialog1.FileName;
textBox1.Text = File.ReadAllText(namaFile);
Menu-File-Save :
if (namaFile == "")
{
saveFileDialog1.Filter = "namaFile (*.txt)|*.txt|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
DialogResult pilihan = saveFileDialog1.ShowDialog();
if (pilihan == DialogResult.OK)
{
//menunjuk file yg akan di save
System.IO.StreamWriter simpan = new
System.IO.StreamWriter(saveFileDialog1.FileName);
simpan.WriteLine(textBox1.Text);
//menyimpan nama file
namaFile = saveFileDialog1.FileName;
//close proses
simpan.Close();
}
}
else
{
System.IO.StreamWriter SaveFile = new
System.IO.StreamWriter(namaFile);
SaveFile.WriteLine(textBox1.Text);
SaveFile.Close();
}
Menu-File-Save As :
saveFileDialog1.Filter = "namafile (*.txt)|*.txt|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
DialogResult pilihan = saveFileDialog1.ShowDialog();
if (pilihan == DialogResult.OK)
{
System.IO.StreamWriter SaveFile = new System.IO.StreamWriter(saveFileDialog1.FileName);
SaveFile.WriteLine(textBox1.Text);
namaFile = saveFileDialog1.FileName;
SaveFile.Close();
}
Menu-File-Exit :
if (textBox1.Text == "")
{
Application.Exit();
}
if (namaFile == "")
{
DialogResult result = MessageBox.Show("File belum disimpan. Do
you wanna save this?", "Warning", MessageBoxButtons.YesNo);
if (result == DialogResult.Yes)
{
saveFileDialog1.Filter = "namafile (*.txt)|*.txt|All files
(*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
DialogResult pilihan = saveFileDialog1.ShowDialog();
if (pilihan == DialogResult.OK)
{
System.IO.StreamWriter SaveFile = new
System.IO.StreamWriter(saveFileDialog1.FileName);
SaveFile.WriteLine(textBox1.Text);
namaFile = saveFileDialog1.FileName;
SaveFile.Close();
}
}
else
{
Application.Exit();
}
}
else
{
System.IO.StreamWriter SaveFile = new
System.IO.StreamWriter(namaFile);
SaveFile.WriteLine(textBox1.Text);
SaveFile.Close();
Application.Exit();
}
Menu-Edit-Cut :
textBox1.Cut();
Menu-Edit-Copy :
textBox1.Copy();
Menu-Edit-Paste :
textBox1.Paste();
Menu-Edit-Select All :
textBox1.SelectAll();
Nah, demikian codingan yang sangat sederhanan ini, semoga membantu :)
