C# Classwork - The RichTextBox/Text Editor

This is a very basic text editor, rendered using the RichTextBox control.




The designing (drag and drop) should be easy, the list of code for each text controls are given below.


1) New (clears textbox)

richTextBox.Clear();

2) Open

OpenFileDialog openFile1 = new OpenFileDialog();
openFile1.ShowDialog();

richTextBox.LoadFile(openFile1.FileName, RichTextBoxStreamType.PlainText);

3) Save

richTextBox.SaveFile("C:\\DENIS.TXT", RichTextBoxStreamType.PlainText);

4) Save As

SaveFileDialog saveFile1 = new SaveFileDialog();
saveFile1.ShowDialog();
saveFile1.DefaultExt = "*.txt";

richTextBox.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);

5) WordWrap

if (richTextBox.WordWrap == true)
  richTextBox.WordWrap = false;
else
  richTextBox.WordWrap = true;

6) Font

FontDialog fontDialog1 = new FontDialog();
fontDialog1.ShowDialog();

richTextBox.Font = fontDialog1.Font;

7) Color

ColorDialog colorDialog1 = new ColorDialog();
colorDialog1.ShowDialog();

richTextBox.ForeColor = colorDialog1.Color;

8) Undo, Cut, Copy, Paste

private void undoToolStripMenuItem_Click(object sender, EventArgs e)
{
  richTextBox.Undo();
}

private void cutToolStripMenuItem_Click(object sender, EventArgs e)
{
  richTextBox.Cut();
}

private void copyToolStripMenuItem_Click(object sender, EventArgs e)
{
  richTextBox.Copy();
}

private void pasteToolStripMenuItem_Click(object sender, EventArgs e)
{
  richTextBox.Paste();
}

9) Number of Characters

MessageBox.Show("Number of Characters : " + richTextBox.Text.Length);

10) Number of Words

int iWords = 1;
for (int i = 0; i < richTextBox.Text.Length; i++)
{
    if (richTextBox.Text[i].ToString() == " ")
        iWords++;
}

MessageBox.Show("Number of words: " + iWords);

11) Number of Paragraphs

int iParagraph = 1;

for (int i = 0; i < richTextBox.Text.Length; i++)
{
  if (richTextBox.Text[i].ToString() == "\n")
      iParagraph++;
}

MessageBox.Show("Number of Paragraphs: " + iParagraph);
