http://www.vb-helper.com/HowTo/srchbox.zip Purpose Make a simple search form for a RichTextBox. Method Use a second form that sets the controls SelStart and SelLength properties. Unfortunately the RichTextBox does not show its selection unless its form is active. The search frm sets the focus to this control after it finds the target string. This example makes the search form a child of the main form so it is always on top of the main form. Disclaimer This example program is provided "as is" with no warranty of any kind.
