I'd forgotten I wrote that <s~>

and it raises a couple of interesting points about screen scraping:
the code worked when I wrote it, but doesn't now - for two reasons:

the target site has changed slightly

amongst other things this means you end up at a 'redirected default'
page - one of the ms security patches (I think) results in http post
commands being rejected by such pages. Try this:

cURL = "http://www.hawthornecottage.com/andy/"; && your url here
oHttp = createobject("Microsoft.XmlHttp")
oHttp.Open("POST", cURL, .F.) && Synchronous
? oHttp.Send("")
gcc= oHttp.ResponseText
n1= AT([NAME="Graphic2"],gcc) && you do
n2=AT('ALT=',SUBSTR(gcc,n1)) && a lot of
n3=AT('" ', SUBSTR(gcc,n1+n2)) && this stuff
?ALLTRIM(SUBSTR(gcc, n1+n2+3, n3-2)) && when screen scraping
ohttp.abort
ohttp=null
CLOSE ALL
CLEAR ALL
RELEASE ALL

Now try the same thing but using "http://andy.hawthornecottage.com"; *which
goes to the same page*
- it fails and you get a 405 error

P.S.

If anyone wants to try scraping using the dom (with xml - or html come to
that) then as a guide here is some more stuff I posted earlier:

CLEAR
cURL = "http://www.hawthorn-cottage.com/iptry1.asp"; && your url here
oHttp = createobject("Microsoft.XmlHttp")
oHttp.Open("POST", cURL, .F.) && Synchronous
oHttp.Send("")
cX = oHttp.responseText
cY=SUBSTR(cX,AT([<body>],cX)+6,AT([</body>],cX)-AT([<body>],cX)-6)
cZ=CHRTRAN(cY,CHR(9)+CHR(10)+CHR(13),' ')
cZ = ALLTRIM(cZ)
?cZ && REMOTE = you
cURL = "http://www.hawthorn-cottage.com/iptryDOM.asp"; && your url here
oHttp.Open("POST", cURL, .F.) && Synchronous
oHttp.Send("")
oX = oHttp.responseXML
?oX.getElementsByTagName('txt').item(0).text && REMOTE = you
?oX.getElementsByTagName('txt').item(1).text && LOCAL = web server
?oX.getElementsByTagName('txt').item(2).text && = web server name
?ohttp.abort
CLOSE ALL
RELEASE ALL
