Hi there,

On the CD, which ships with the Delphi package (version 4 or 5) there is a demo of some Internet explore application.

I want to use this program to get (automatically) the source (HTML) code of the website I'm looking.

Can somebody help me out?

Please provide me with good examples, I'm just a beginner (3 years).

gr.,
Roosiedb

Hi roosiedb,

use THTTPCli component, it can be downloaded for free at
http://overbyte.alexid.fr/frame_index.html

here is sample how to get source code into memo:

var RCV: TMemoryStream;
    HTTP :THTTPCli;
begin
  HTTP := THTTPCli.Create(nil);
  {
  HTTP.Proxy := 'proxyname';
  HTTP.ProxyPort := '1080';
  }
  HTTP.NoCache := true;
  RCV := TMemoryStream.Create;
  HTTP.RcvdStream := RCV;
  HTTP.URL := 'http://www.yahoo.com';
  HTTP.Get;

  RCV.Seek(0, soFromBeginning);
  Memo1.Lines.LoadFromStream(RCV);
  RCV.Free;
  HTTP.Free;
end;

or, if you're using IE:

var
  HTMLDocument: IHTMLDocument2;
  PersistFile: IPersistFile;
begin
  ...
  HTMLDocument := WebBrowser1.Document as IHTMLDocument2;
  PersistFile := HTMLDocument as IPersistFile;
  PersistFile.Save(StringToOleStr('test.htm'), True);

  while HTMLDocument.readyState <> 'complete' do
    Application.ProcessMessages;
     ...
end;

Please leave any comments here within the next seven days.
