Hi,

You can try this foe the enter Key:

vb Code:
  1. ' The keypressed method uses the KeyChar property to check 
  2.         ' whether the ENTER key is pressed. 
  3.  
  4.         ' If the ENTER key is pressed, the Handled property is set to true, 
  5.         ' to indicate the event is handled.
  6.  
  7.         If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
  8.             e.Handled = True
  9.         End If

For the Backspace use:

vb Code:
  1. If e.KeyChar = Microsoft.VisualBasic.Chr(Keys.Back) Then
  2.             MsgBox("You pressed the Backkey")
  3.         End If

Wkr,
