2) Make the size of the control 0x0
Just like you may want a pushbutton to be invisible sometimes and
visible other times, I want this to only be visible sometimes. It's
context-sensitive. I've tried just about everything, including
putting the second page of a pagepanel, and even using
containercontrols. What I'm finding is that nothing is working
correctly. Using containercontrols worked for this problem but
other controls (such as multi-line editfield) tend to leave behind
artifacts.

I had this problem. On my Rb2006r4 it seems to be intrinsic
behaviour only of the htmlViewer control (bug?).
If you set the viewer control dimensions to 0 x 0 it will disappear
from the windows content area, but it mysteriously regrows and the
right edge of the viewer reappears as a phantom over your other
controls when you resize the window. I solved this problem by
setting the htmlViewer height/width to -5000 x -5000 when I did not
want it to appear and then to positive values when I wanted it to
appear. These large negative values will not be incremented into
positive values no matter what size the window becomes and so the
viewer never achieves a display rectangle within the windows content
area. Naturally, you need to know how large is the biggest
screen the user has, so maybe loop the systems screen(i), test for
dimensions and use a negative multiplier to make it disappear and not
come back no matter what the size the user zooms. For example:
dim largest as integer
//loop to find the largest screen width
To Disappear:
htmlViewer1.width = -(screen(largest).width * 5)
htmlViewer1.height = -(screen(largest) * 5)
Hope this helps...
