Tom:
Yes, this works, but the danger of this method is what happens if the
user resizes the window while
you are "hiding" some of your viewers. If your viewer objects are
locked to the
width/heighth of the window, and the user resizes the window, the hidden
viewers suddenly become wider (the width is no longer 0) and become
partially visible (very ugly!).
A better method might be to move the viewers where they cannot ever
be seen by setting
their top/left coordinates to large negative numbers, which
effectively displays them
somewhere far, far away....where the user will never see them.
Now when the user resizes the window, they will still not be visible
on the screen
until you move them back into position...........but, they are still
resized correctly!
if .........
HTMLviewer (me.control(n)). left) = -20,000
else
HTMLviewer (me.control(n)). left) = leftMargin //where
you want it shown
end if
By using large negative numbers, you are guaranteed that this method
will not break if the screens
become larger/higher resolution in the future
BTW, this method also works for showing/hiding *any* control.......
