September 5th Wedenesday (九月　五日　水曜日）

   For conveience I created a CMessageBar class, it likes wxStatusBar.  It is acutally just a panel on where two
wxStaticText controls was put.  One of those static text controls is represented as a title of a message, another
is used to show the content of a message.  It is not easy to lay out correctly those controls.

  In order to put the message bar at the bottom of the Transfer Panel, I took almost whole this afternoon to do that,
in that there is a button need following the message bar.
