[DUG] Delphi internals - form events

[Dennis Chuah]

In a form OnCreate event, you have access to all components on the form, but 
the Windows handle is not yet created.  You cannot access any property or 
methods that require the presence of a windows handle.  When the OnShow 
fires, the Windows handle has been created - because the VCL only creates 
the handle when the form is shown.
