I made a dialog box which contains one edit box,one list box
and serveral buttons.
Now I want the data displayed on the list box can be
refreshed after I have typed a character in the edit box.
(without doing anything just typing a char. in the box)
I tried to catch the message WM_KEYUP to implement this but
it is not successful.
Now I only can refresh the data by clicking the button
in the dialog box after typing a char. in the box.
