Text Boxes (VB.NET)

• To set the initial focus to a text box you must set the control's TabIndex property to 0.  Be sure that the TabStop property is set to True.
  
• Use the Focus command to move the focus to a particular control:
  txtBox.Focus
  
• To clear the contents of a text box, use a line like txtBox.Text = vbNullString
  
• To display multiple lines in a text box, set the MultiLine property to True and the Scroll Bars property to ScrollBars.Both.
  
• To highlight the text in a text box, use the following sequence of commands:

txt1.Focus( )	' Move the focus to the text box
txt1.SelectionStart = 0	' Set cursor to beginning of box
txt1.SelectionLength = Len(txt1.Text)	' Set length of selection to contents length
