Retrieve and store the images from server URL

ccc_storage · August 19th, 2004, 01:44 AM

Hi,

I receive datafeeds as a .txt format that hold their product inventories including fields for all the product
details like price, description, categories, etc.
Two of those fields are for product image locations for a thumbnail and a larger image file. For instance:

Thumbnail: http://www.x.com/images/thumbnails/imgx.jpg
Full Image: http://www.x.com/images/images/imgx.jpg

Is there a way to write an ASP script that will loop through all the records in the datafeed and
retrieve and store the images? I have no idea how I could do this.

~Thanks

Please specify the format of the text file. If it contains a text block that is getting repeated for each product, this is possible.

Thanks for reply,
Datafeed file(.text) format like...

Top row contains colum name
each values separated with tab

Is there any programming way?

AFAIK, there is no way other than fetching image file through an FTP component. There are many FTP components like (dart, chillkat etc.). You can use one of them to fetch the images from remote server. But this is not an advisable way. You need username and password to connect to remote server. The path etc. of remote server may change over time in which case you have to make changes to your code.

You can put the http path as the source of image. Like
<img src="http://www.x.com/images/thumbnails/imgx.jpg">

I think the http path is also got from the feed. Then you do not have to change the code when the image path changes at the remote server.

Hey ccc_storage,

This should do it...

Code:

Dim xmlHttp
Set xmlHttp = Server.CreateObject("MSXML2.XmlHttp.4.0")
Call xmlHttp.open("GET", "[target file]")
Call xmlHttp.send()

Dim stream
Set stream = Server.CreateObject("ADODB.Stream")
stream.Type = adTypeBinary
Call stream.Open()
Call stream.Write(xmlHttp.responseBody)
Call stream.SaveToFile("[save as file]", adSaveCreateOverWrite)
Call stream.Close()
Set stream = Nothing

Set xmlHttp = Nothing

HTH,

Chris

Hello Chris,

Thanks a lot for showing me another way.

But the following line gives an error.

stream.Type = adTypeBinary

The error is:

Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.

May I know what is the problem ?

Hi,

You need to reference the ado constants (or substitute in the appropriate values), this was recently discussed in the following thread...
