Dear Johan,
First you should click on Yahoo.js.
Clicking on URLGet without giving URL gives you
the errors.
This little utility is described in the newsletter
(6/2001)
If you receive <FONT
face="Courier New" size=2>"The server name or adress could not be resolved"
it means that URLGet can get the
address of DNS server. Please check
your
TCP/IP settings.
URLGet program uses default TCP/IP
connection
as defined in Internet Explorer
Settings/Connections.
You can check manually if the URLGet itself
works correctly
on your machine by issuing the following
command:
URLGet <A
href="">http://www.yahoo.com<FONT
size=2> index.html
This should get the home page of yahoo and
store it to local
index.html page. If it works also the script
should work.

Subject: [amibroker] Automatic
download ? (until it works)
Hello group,I hope I find someone in the groupwho
can help!I'm trying to automate daily updates from Yahoo, but still
having problems. I'm trying it for a week now, but don't
succeed. I created a folder C:\Yahoo and copied the URL Get.exe
program and the file Yahoo.js there. But when I doubleclick on the
URL Get.exe to run the program, I retrieve the following message : "You
have to define URL and local file name in program arguments" ! So, where
do I have to do that? And when I doubleclick on Yahoo.js, I retrieve
the following message : URLGET : "The server name or adress could notbe
resolved" !I'm not that good in English (my native language is
Dutch) so maybe I misunderstood the instructions (and yes, I read all
newsletters). It's to difficult for me, so, is there anyone who can
explane it, step by step, using simple terms?I included the script
of the Yahoo.js file so you can check it.PLEASE, HELP ME
