Windows Form - Lec12 (Workshop on C# Programming: Learn to Build)
- 2. C# Day 2 Lecture12: Form Design
- 3. Form Design: MessageBox using System; using System.Text; using System.Windows.Forms; public class HelloWorld { public static void Main() { MessageBox.Show("Hello World!"); } }
- 4. Form Design: TextBox private void button1_Click(object sender, EventArgs e) { text1.Text = textBox1.Text.ToString(); text2.Text = textBox2.Text.ToString(); MessageBox.Show("You've successfully logged in.","Log in"); }
- 5. Form Design: Label private void button1_Click(object sender, EventArgs e) { label1.Text = label1.Text.ToString().ToUpper(); label2.Text = label2.Text.ToString().ToLower(); MessageBox.Show("You've successfully logged in.","Log in"); }
- 6. Form Design: CheckBox private void checkBox1_CheckedChanged(object sender, EventArgs e) { if(checkBox1.Checked) textBox2.UseSystemPasswordChar = false; else textBox2.UseSystemPasswordChar = true; } }
- 7. Form Design: CheckBox private void button1_Click(object sender, EventArgs e) { textBox1.Text = textBox1.Text.ToString(); textBox2.Text = textBox2.Text.ToString(); MessageBox.Show("You've successfully logged in.","Log in"); } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (checkBox1.Checked) { textBox2.UseSystemPasswordChar = false; } else { textBox2.UseSystemPasswordChar = true; } }
- 8. Form Design: RadioButton string radio="radio"; private void radioButton1_CheckedChanged(object sender, EventArgs e) { radio = "Button1"; } private void radioButton2_CheckedChanged(object sender, EventArgs e) { radio = "Button2"; }
- 9. Form Design: PictureBox private void pictureBox1_Click(object sender, EventArgs e) { pictureBox1.SizeMode.GetType(); }
- 10. Windows Form Design • Let's design a Form.
- 13. Windows Form Design: Make PDF • Write some code to generate a PDF. • Hint: - First design a form - Use some methods
- 14. Windows Form Design: Make PDF
- 15. Windows Form Design: Make PDF using System.IO; using iTextSharp.text; using iTextSharp.text.pdf; private void button1_Click(object sender, EventArgs e) { Document doc = new Document(iTextSharp.text.PageSize.LETTER, 25, 25, 30, 20); PdfWriter myPDF = PdfWriter.GetInstance(doc, new FileStream(textBox1.Text.ToString() + ".pdf", FileMode.Create)); Paragraph pri = new Paragraph(textBox2.Text.ToString()); doc.Open(); doc.Add(pri); doc.Close(); MessageBox.Show("Saved"); }
