title: Textbox SelectionStart, SelectionEnd and Caret (Cursor) Position
body: <p>This could be very simple.</p>
  
  <p>I have a textbox on a WinForm, Text = "ABCDEFGH". I need to select "BCD" and leave the I-Beam (cursor, caret, blinking '|') right between the 'A' and the 'B'. Setting SelectionStart = 1 and SelectionLenght = 3 doesn't work and I can't figure it out.</p>
