1、更改webbrowser的cookie路径

2、延时1秒，启动webbrowser

3、更改webbrowser的cookie路径为原来的

4、登录账号

5、记录下cookie

6、设置cookie, internetsetcookie

7、测试是否成功

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
    Button1: TButton;
    Memo1: TMemo;
    Edit1: TEdit;
    procedure Button1Click(Sender: TObject);
private
    { Private declarations }
public
    { Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.dfm}

uses unitFunc;

function GetIECookiePath():string;
var
    UserProfile :string;
    Key ,Name ,CookiePath ,CachePath :string;
begin
    UserProfile := GetEnvironmentVariable('USERPROFILE'); //获取环境变量

    //...1、Cookies 文件夹路径
    Key := 'Software/Microsoft/Windows/CurrentVersion/Explorer/User Shell Folders';
    Name := 'Cookies';
    CookiePath := regRead(HKEY_CURRENT_USER ,Key ,Name);
    CookiePath := StringReplace(CookiePath,'%USERPROFILE%',UserProfile,[rfReplaceAll]);

    //...2、Cache 文件夹路径
    Key := 'Software/Microsoft/Windows/CurrentVersion/Explorer/User Shell Folders';
    Name := 'Cache';
    CachePath := regRead(HKEY_CURRENT_USER ,Key ,Name);
    CachePath := StringReplace(CachePath,'%USERPROFILE%',UserProfile,[rfReplaceAll]);

    Result := CookiePath;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
    CookiePath :string;
    fs :TFileStream;
    ms :TMemoryStream;
    ss :TStringStream;
begin
    CookiePath := GetIECookiePath + '/index.dat';

    fs := TFileStream.Create(CookiePath,fmShareDenyNone);
    ms := TMemoryStream.Create;
    ss := TStringStream.Create('');
    try
        fs.Position := 0;
        ms.CopyFrom(fs,fs.Size);
        fs.Position := 0;
        ss.CopyFrom(fs,fs.Size);
    finally
        fs.Free;
    end;
    memo1.Text := ss.DataString;
    ss.Free;
    ms.Free;
end;

end.

例如将一个带背景的LABEL变成一个TIMAGE图片类型，可以这样做：
image1.width:=label1.width;
image1.height:=label1.height;
label1.perform(WM_PAINT,image1.Canvas.Handle,0);
