URLMonLibrary
Locked
 
|
Hi All
I am trying to automate the downloading of regularly updated information from the web. I would like to avoid the complications of using the Internet Explorer control, so I have been trying to use URLMonLibrary>>urlDownload:toFile or alternatively IStream class>>onUrl:, which also uses features of URLMonLibrary. The system seems to work when the download is from a 'standard' URL, but the input I need to get my data includes an asp query; the full line is: 'http://www.statistics.gov.uk/STATBASE/tsdataset.asp?vlnk=7174&More=N&All=Y' Whenever I try this, the call fails in URLMonLibrary with the HRESULT value 16r800C0008 (Unknown facility). The comments in some of the URLMonLibrary methods say that the HRESULT values are not all documented. Does anyone have any experience of using such calls, or can say whether the presence of the asp query will stop it working? If not, I fear it will be back to the IE control (sigh). Many thanks Peter Kenny |

Are you expecting to get series information on that page? As I just get a
web page where I have to fill in some date, time boxes... which makes me wonder if you have a cookie or something in your browser and this might be whats giving you the problem?

I was expecting a series, so clearly there is some problem in my url. I got
there by clicking a button in a previous page, and the page with the series data has the url I quoted in its title bar. As far as I can see, the site has not put a cookie in my system. It just seems that the call will not work if I have an asp in the url. Maybe I will have to use IE, and program it to simulate a button push.

Have you tried Steve's HTML client? The MS binaries have some weird interactions with IE (e.g on/off line setting), and they of course share its security problems. Since you are interested in one site, it would likely need to be hacked for there to be a risk on the latter, but once this works you might want to expand to other sites.

However, the problem with the URL that Tim identified (see post above) may mean I have to stick to IE. The site seems to be designed with manual access in mind, and it looks as though addressing it just by inputting a URL is difficult. Thanks again Peter |

The URLMon dll calls you are accessing are performing an HTTP GET. I think you would be better off using Steve Warings HTTP client. Regards Blair |

I have installed Steve Waring's package, and have managed to solve my problem. I couldn't get the POST to work, but I found another route involving only GET calls. Just for future reference, could anyone tell me where I went wrong. The method SptHTTPRequest>>send is described as: Send the request with no entity (typical for a GET Request). Since the whole point of POST is to send the entity, how do I do that? This group really is marvellous! Not only solving my Smalltalk problems, but diagnosing HTML problems as well - and on a Sunday too! Thanks to all who posted - and also to Steve for such a clever package. Peter |
