You can use Select Case to handle the event.

'key press event
Select Case Convert.ToInt32(e.KeyChar)
   Case 48 to 57  ' numbers
   Case 65 to 122 ' letters
   Case Keys.Delete
      e.Handled = True ' true means the keypress is suppressed
End Select


Ascii values.

I believe that the ASCII value for the delete key is 127 in decimal form. Are you looking for the press key event to occur within a windows application (GUI app)?

@ItIntern3: You are correct. ASCII code for DEL is 0x7F or 127 in decimal.
It is however recommended that you use the Keys.Delete constant for the sake of portability.
