关于webbrowser的问题

[mmkill]

用webbrowser控件浏览出一个网页后，怎样用语句实现选中一个数据块然后复制到剪切板的功能，即Ctrl+A,然后Ctrl+C。

[mmkill]

如果能选中其中的一块更好，加分！！！

我的想法, 只能先取得webbrowser中的html源碼, 然後, 分析你要的起始位和終止位, copy 到剪切板

...get/save the HTML Code from a TWebbrowser?

uses
ActiveX;

function WB_SaveHTMLCode(WebBrowser: TWebBrowser; const FileName: TFileName): Boolean;
var
ps: IPersistStreamInit;
fs: TFileStream;
sa: IStream;
begin
ps := WebBrowser.Document as IPersistStreamInit;
fs := TFileStream.Create(FileName, fmCreate);
try
sa := TStreamAdapter.Create(fs, soReference) as IStream;
Result := Succeeded(ps.Save(sa, True));
finally
fs.Free;
end;
end;

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

procedure TForm1.Button1Click(Sender: TObject);
begin
WB_SaveHTMLCode(Webbrowser1, 'c:\test.txt');
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
WB_GetHTMLCode(Webbrowser1, Memo1.Lines);
end;
