You can use the WIDGET_ACTIVEX() function and you could use SPAWN
(iexplore "insert your url here"). The issue you'll run into is
determining if an alternate browser is available. To be safe I would
stick with IE but you could write a procedure which would look for
Opera, Moz, Firefox in at least their default locations.
When WIDGET_ACTIVEX was born, I wrote a windows only HTML help widget
which demonstrates the use of WIDGET_ACTIVEX. It is simply an IDL
widget window with IE embedded in it (no controls, although right clicks
in the window bring up the IE context menu). I don't know how specific
the COM ID is so I can't guarantee that this will work with all versions
of IE.
You can pick up Dialog_WinHTMLHelp here:
