Can you develop your own webparts, or are you looking for a way to
do it within an already built webpart? I see you already have a
chunk of info coming back, but it doesn't look very useful.

There are some webserivces our there that can pull stock  info for
you (formatted in xml)... http://ws.invesbot.com/stockquotes.asmx is
a good one. You can create an webpage (asp, aspx, etc) that calls
this webservice, then use the page  viewer web  part to display the
webpage on your sharepoint page. You can set the size and shape of
the page viewer part  so it will only display what you want.

You could also create your own ticker web part, which is a little
more involved, but is a nicer looking solution.

When ever I try to add reference to a web  service I get the following
error:

The underlying connection was closed: The proxy name could not be
resolved, verify correct proxy configuration. I did check my proxy
configuration but not able to establish whatz making the problem. Can
you provide little instruction...

Since you are getting the data from Yahoo (a URL accessible resource),
why not use a Data View Web Part?

Ask more questions if that doesn't get you going in the right direction.

I tried putting in Page Viewer web  part but the context prompts with the
option to Save or Open or cancel dialog box. I am not able to show it on
the dashboard. The file is in CSV extension. Here it is.... I just want
to load this url and take the price of the quote.

http://finance.yahoo.com/d/quotes.csv?s=" +504067.BO+ "&f=sl1d1t1c1ohgv

I am not able to load this web site through a Code. I get a runtime
error stating the Underlying Connection is closed. I tried a lot to fix
it but no help.
