Does anybody know how you can extract an image fron a webpage loaded into
a webbrowser control and either save it to file OR save it in a database?
Cheers,

You need to read in the image as if you were reading in a webpage....firs t,
open the web page and parse the path to the image...then, you can use the
following code to get the byte-array of the image and store to a file or
data column in a database.
// BEGIN C#
string url =
@"http://www.co.merced.c a.us/CountyWeb/images/GeneralActive.g if";
HttpWebRequest request =
(HttpWebRequest ) WebRequest.Crea te(url);
HttpWebResponse response =
(HttpWebRespons e) request.GetResp onse();
byte[] bytes;
using (Stream stream = response.GetRes ponseStream()) {
bytes = new byte[response.Conten tLength];
stream.Read(byt es, 0, bytes.Length);
}
// Now we have a byte array to do as we wish, saving to a file
now.
FileStream fs = File.Create(@"C :\GeneralActive .gif");
fs.Write(bytes, 0, bytes.Length);
fs.Close();
// OR write to a database.
// To do this, create an IMAGE (SQL Server) column and just copy
// the byte array into the field for a DataRow. An Image column
// maps to a byte-array in a DataColumn in a DataRow.
// END C#
There may be an easier or better way in a more recent version of the .Net
Framework though... :)
