I found that this approach (SHOW WINDOW ChildForm) does not seem to
actually fire any events of ChildForm - not when I tried it and
ChildForm not only WEXISTs but is also WVISIBLE. However I found that
the following approach (which avoids having a PUBLIC ChildWindow and
would therefore, I hope, be preferred by Tracy) also works very well:
IF NOT WEXIST("ShowData")
DO FORM ShowData WITH THISFORM.TargetForm,"aShowData"
THISFORM.ChildForm = ShowData
ELSE
THISFORM.ChildForm.Refresh(THISFORM.TargetForm,"aShowData")
ENDIF
By storing a reference to ShowData in the ChildForm property of the
parent/calling form the first time (DO FORM Showdata) I am able to
reference subsequently it if it already exists.
Cheers
