Hyphenate words with TX Spell .NET

This sample uses the text of a TextBox as the input for TX Spell .NET to hyphenate a word. Additionally, it shows how to adjust typical settings such as the minimum number of characters at a word begin and word end.

Start the application and type in a word into the first TextBox. The bottom RichTextBox shows the hyphenated word immediately including the hyphenation positions.

The required code is straightforward. The text from the TextBox is used in the Proofing.TXSpell.GetHyphenationPoints method of TX Spell that returns the possible hyphenation points. For demo purposes, these points are used to split the word into separate syllables, which are concatenated with a hyphen to illustrate the potential hyphenation points.

string sWordToHyphenate = textBox1.Text;
int[] iHyphenationPoints = txSpellChecker1.GetHyphenationPoints(sWordToHyphenate);

var parts = new List<string>(iHyphenationPoints.Length);

int index = 0;
foreach (int length in iHyphenationPoints)
	parts.Add(sWordToHyphenate.Substring(index, length - index));
	index = length;

foreach (string part in parts)
	richTextBox1.SelectionColor = Color.Blue;
	richTextBox1.SelectedText = part;
	richTextBox1.SelectedText = "-";
	richTextBox1.Select(richTextBox1.SelectionStart - 1, 1);
	richTextBox1.SelectionColor = Color.Red;
	richTextBox1.SelectionStart += 1;
[Visual Basic]
Dim sWordToHyphenate As String = TextBox1.Text
Dim iHyphenationPoints As Integer() = TxSpellChecker1.GetHyphenationPoints(sWordToHyphenate)

Dim parts = New List(Of String)(iHyphenationPoints.Length)

Dim index As Integer = 0
For Each length As Integer In iHyphenationPoints
	parts.Add(sWordToHyphenate.Substring(index, length - index))
	index = length

For Each part As String In parts
	RichTextBox1.SelectionColor = Color.Blue
	RichTextBox1.SelectedText = part
	RichTextBox1.SelectedText = "-"
	RichTextBox1.[Select](RichTextBox1.SelectionStart - 1, 1)
	RichTextBox1.SelectionColor = Color.Red
	RichTextBox1.SelectionStart += 1
