Bold Specific Words

Is it possible to bold specific words in say a Rich Textbox on a form.

e.g. The cat sat on the mat.

The phrase would be coded as a variable or constant and entered as the Rich Textbox text at runtime.

This is simple with HTML. I wondered if there was an equivalent feature in VB.Net

Thanks,

This might give you a start:

Code Snippet

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim boldFont As Font = New Font(RichTextBox1.Font, FontStyle.Bold)

Dim pos As Integer = 0

While pos < RichTextBox1.TextLength AndAlso _

RichTextBox1.Find("cat", pos, RichTextBoxFinds.WholeWord) <> -1

RichTextBox1.SelectionFont = boldFont

pos += RichTextBox1.SelectionLength

End While

End Sub

Thanks BinaryCoder. That was very helpful. With a bit of modification to suit my requirements I got everything to work fine. Your code pointed me in the right direction.

Thanks again.
