<DIV><FONT face=Arial size=2>Hi Matthew,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you very much. I tried a piece of code
(modified from the class for the UML) as follows in the Draw method of the
decorator class and it throws an exception #0x87650035. I don't know what this
exception code means.</FONT></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The only difference between my code and the UML
class decorator code is that the latter one is in the method Initialize(), while
my code is in Draw(). It seems that the value of the FCO's attribute can only be
retrieved during initialization of this decorator object. But I want to let the
decorator to display according to the dynamically changed attribute
value.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any ideas?</FONT></DIV>
