I find solution:

Dim index As Int32 = RTB.GetTextWithNewLineStyle().IndexOf("Private Sub ")

Dim vp As Point = RTB.ConvertOffsetToVirtualPosition(index)

Dim Offset As Int32 = RTB.ConvertVirtualPositionToOffset(vp) / 2 - 1 'for Unicode encoding

Dim Offset As Int32 = RTB.ConvertVirtualPositionToOffset(vp) 'for ASCII
