No, indeed it isn't. I am using ExecuteMapAction to zoom to a selection, but
when the selection is a point object, the viewer is zoomed in so far that
there is no context visible, and one has to zoom out a long way before one
can see any other features. I therefore simply wanted to change the scale of
the map after zooming to the selection.

My error - apologies. There is now no error thrown, so presumably the method
is being called successfully. However, what on earth does it actually do?
What, in real terms, does it mean to change the scale of the legend? I
assumed that SetScale() was simply an easy way to change the scale of the
map, without having to bother with the coordinates, but plainly this is not
the case.

Thanks for all your help, though. The method you described works perfectly
for me.

Cheers

Tom
