Description: This module implements a class t hat coordinates the operation
|
|
between the edit control and combo box used for entering byte values.
|
|
The name "XBytes" is used because the control can represent
|
|
KBytes, MBytes, GBytes etc.
|
|
|
|
The cooperation between edit control and combo control is required
|
|
so that the user can enter a byte value in the edit control then
|
|
indicate it's order (KB, MB, GB...) using a selection from the combo box.
|
|
|
|
A simple external interface is provided to initially set the
|
|
object's byte value then retrieve the byte value when needed. The
|
|
object's client is also required to call two member functions when
|
|
the parent dialog receives an EN_UPDATE notification and a CBN_SELCHANGE
|
|
message. The XBytes object handles all of the value scaling
|
|
internally.
