Re: PreCreateWindow() & CListBox
Is your dialog a CFormView or CDialog I believe you will have to use the
PreSubClassWindow() method since PreCreateWindow() won't be called. I'm not
sure it will work there either since the controls are created before they
are subclassed.. You may want to try this in the OnCreate().

In my CListBox-deriviation, i want to have some StyleFlags always set
before the Control is created. So I thought to overload
PreSubclassWindow() and PreCreateWindow(). The first one is called but
cant set LBS_OWNERDRAWVARIABLE, the PreCreateWindow() is not called at
all;-\
Can anyone explain why it is not called and what to do about it? I
definitively need a way to change the styleflags *after* the resources
are loaded and *before* the windows get created - wasn't
PreCreateWindow() meant exactly for that...?
- thanx for any insight -.rhavin;)
