PROGRAMMING READABILITY

MEANINGFUL IDENTIFIERS

I use meaningful identifiers like Enter Key(txtEnterKey), ASCII VALUE(lblResult), QUIT(cmdQuit), Case  and CLEAR(cmdClear). it is readable because I use simple variable.

LOGIC STRUCTURE

I use case and switch for the iteration, and if then statement.

CODING PRACTICE 

Private Sub txtEnterKey_KeyDown (KeyCode As Integer, Shift As Integer)

Select Case KeyCode
         Case vbKeyDelete
          lblResult.Caption="Delete Pressed!"
          txtEnterKey.Text="(Delete)"
         Case vbKeyInsert
          lblResult.Caption="Insert Pressed!"       
          txtEnterKey.Text="(Insert)"
          Case vbKeyEnd
          lblResult.Caption="End Pressed!"       
          txtEnterKey.Text="(End)"
 
End Select
End Sub
