FrmShowObject will only try to draw the object if the form itself has been
drawn. That is, if the form has not yet been drawn, you can still call
FrmShowObject or FrmHideObject and this will update the usable flags for
the objects but will not draw them (and will not generate any errors.)
This is another excellent example of where FrmShowObject is an improvement
over CtlShowObject! CtlShowObject can't make the "is the form visible"
test, because the control doesn't know about the form.
