Problem/Question/Abstract:

Get the HTML Code out of all Internet Explorer Instances?

Answer:

uses
MSHTML_TLB, ActiveX;

function GetHTMLCode(WB: IWebbrowser2; ACode: TStrings): Boolean;
var
ps: IPersistStreamInit;
s: string;
ss: TStringStream;
sa: IStream;
begin
ps := WB.document as IPersistStreamInit;
s := '';
ss := TStringStream.Create(s);
try
sa := TStreamAdapter.Create(ss, soReference) as IStream;
Result := Succeeded(ps.Save(sa, Bool(True)));
if Result then
ACode.Add(ss.Datastring);
finally
ss.Free;
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
ShellWindow: IShellWindows;
WB: IWebbrowser2;
spDisp: IDispatch;
IDoc1: IHTMLDocument2;
k: Integer;
begin
ShellWindow := CoShellWindows.Create;
// get the running instance of Internet Explorer
for k := 0 to ShellWindow.Count do
begin
spDisp := ShellWindow.Item(k);
if spDisp = nil then
Continue;
// QueryInterface determines if an interface can be used with an object
spDisp.QueryInterface(iWebBrowser2, WB);
if WB <> nil then
begin
WB.Document.QueryInterface(IHTMLDocument2, iDoc1);
if iDoc1 <> nil then
begin
WB := ShellWindow.Item(k) as IWebbrowser2;
begin
// Add HTML Code to Memo
Memo1.Lines.Add('****************************************');
Memo1.Lines.Add(WB.LocationURL);
Memo1.Lines.Add('****************************************');
GetHTMLCode(WB, Memo1.Lines);
end;
end;
end;
