How to get image from Webbrowser page

[=?Utf-8?B?UGF1bCBT?=]

Hi

How can I programmatically save an image from a page locally?

The same as right-click the image and select 'Save as'

You can't, at least, not natively...

Every modern browser is written specifically to prevent this sort of
programmatic interaction with the hardware and software on which the client
browser is running...

The only possible solution would be to write an ActiveX control, but that
would limit your web app to Microsoft IE, and you would need to seriously
compromise browser security just to get it to run at all...

Hi

I thought it could be done reading bytes out of the httprequest or perhaps
scripting

I know the layout of the page and I know the name of the image

<img border="0" src="http://www.xyz.dk/UI/Images/Charts/APCP100_da_36.png"/>

Not familiar with the web browser control but yes, you shouldn't have those
limitations that applies to a stand alone browser as you are working from
your own application.

So you could :
- parse the page to get the image location and download the image
- you could also perhaps get the image from the cache avoiding to download
it again

Or if each and every request is seen by your application you could capture
those bytes (but I'm not sure wether you can get an event for image requests
triggered by the main doucment ??)

If that's the case, then I misinterpreted the OP and believed that he was
referring to a browser-based app since he posted in the ASP.NET newsgroup...

do you mean something like this: ?

System.Net.HttpWebRequest httpRequest = (HttpWebRequest)
System.Net.WebRequest.Create(imageURL);
System.Net.HttpWebResponse httpResponse =
(HttpWebResponse) httpRequest.GetResponse();
System.IO.Stream httpResponseStream =
httpResponse.GetResponseStream();

System.Drawing.Image imageIn =
System.Drawing.Image.FromStream(httpResponseStream );

httpResponseStream.Close();
httpResponse.Close();

Hi Siccolo

I think this is close, but it looks as if you see the url to only contain
the image. The image is contained in a page. I know both name of the image
and the structure of the page. It does not change - only the image - it's a
weather report and for scurity reason this is the only way I can get the
image.

Thanks for the effort

That really depends on what programming software you're using...
