In VB.Net, is it possible to highlight ALL instances of a phrase instead of only a single instance of it, for example: txtView.SelectionStart = txtView.Find("ERROR: Invalid command entered.") txtView.SelectionColor = Color.Red This would highlight "ERROR: Invalid command entered.", however if my RichTextBox text is: ERROR: Invalid command entered. < Only this line will highlight ERROR: Invalid command entered.
