"p.s. the server in my university haven't got a internet toolkit, can
i still control it?
Yes. In general there are two ways to control VIs over the web. The
first is by remote panel. It does not require any toolkits. You have
to make sure the web server is enabled, and that your access settings
are configured correctly (which it sounds like you have done). You
can then use Tools>>Web Publishing Tool... to help you build a web
page which includes an embedded control for the specified VI. Note
that the client machine will need to have the LV run time engine.
The second method for controlling a VI over the web is to use CGI with
the Internet Toolkit. The advantage of this method is that you don't
need the LV run time engine on the client. The disadvantage
is that
it is much more complex, and doesn't provide the client with a true
front panel image of the VI (you can fake this, but it isn't trivial).
Plus, you need to have a copy of the Internet Toolkit on your server.
As the other post mentioned, if you are still having trouble with
using remote panel, make sure the client right-clicks on the VI to
gain control (LV7.0 allows the user to create web pages which
automatically attempt to gain control of the requested VI).
Hope this helps.
