Problem/Question/Abstract:

How to save all TWebbrowser frame sources

Answer:

uses
ActiveX;

function TForm1.GetFrame(FrameNo: Integer): IWebbrowser2;
var
OleContainer: IOleContainer;
enum: IEnumUnknown;
unk: IUnknown;
Fetched: PLongint;
begin
while Webbrowser1.ReadyState <> READYSTATE_COMPLETE do
Application.ProcessMessages;
if Assigned(Webbrowser1.document) then
begin
Fetched := nil;
OleContainer := Webbrowser1.Document as IOleContainer;
OleContainer.EnumObjects(OLECONTF_EMBEDDINGS, Enum);
Enum.Skip(FrameNo);
Enum.Next(1, Unk, Fetched);
Result := Unk as IWebbrowser2;
end
else
Result := nil;
end;

// Load sample page

procedure TForm1.Button1Click(Sender: TObject);
begin
Webbrowser1.Navigate('http://www.warebizprogramming.com/tutorials/html/framesEx1.htm');
end;

// Save all frames in single files

procedure TForm1.Button2Click(Sender: TObject);
var
IpStream: IPersistStreamInit;
AStream: TMemoryStream;
iw: IWebbrowser2;
i: Integer;
sl: TStringList;
begin
for i := 0 to Webbrowser1.OleObject.Document.frames.Length - 1 do
begin
iw := GetFrame(i);
AStream := TMemoryStream.Create;
try
IpStream := iw.document as IPersistStreamInit;
if Succeeded(IpStream.save(TStreamadapter.Create(AStream), True)) then
begin
AStream.Seek(0, 0);
sl := TStringList.Create;
sl.LoadFromStream(AStream);
sl.SaveToFile('c:\frame' + IntToStr(i) + '.txt');
//  memo1.Lines.LoadFromStream(AStream);
sl.Free;
end;
except
end;
AStream.Free;
end;
end;

end.
