Okay hier ein Beispiel mit Code.

frmMainU:

Delphi-Quellcode:

unit frmMainU;

interface

uses
  frmSettingsU, DatabaseU, VirtualTrees, IniFiles, ....;

type
  TfrmMain = class(TForm)
    btnSettings: TButton;
    vst: TVirtualStringTree;
    procedure btnSettingsClick(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  frmMain: TfrmMain;
  database: TMyDatabase;

implementation

{$R *.dfm}

procedure TfrmMain.btnSettingsClick(Sender: TObject);
var
  frmSettings: TfrmSettings;
begin
  frmSettings := TfrmSettings.Create(nil);
  try
    frmSettings.ShowModal;
  finally
    frmSettings.Free;
  end;
end;

procedure TfrmMain.FormCreate(Sender: TObject);
var
  ini: TInifile;
begin
  database := TMyDatabase.Create;

  ini := TIniFile.Create('settings.ini');
  try
    database.databasePassword := ini.ReadString('Database', 'password', '');
    database.databaseName := ini.ReadString('Database', 'name', '');
    vst.Enabled := ini.ReadBool('VST', 'enable', true);
  finally
    ini.Free;
  end;
end;

procedure TfrmMain.FormDestroy(Sender: TObject);
begin
  database.Free;
end;

end.

frmSettingsU:

Delphi-Quellcode:

unit frmSettingsU;

interface

uses
  IniFiles, ...;

type
  TfrmSettings = class(TForm)
    edtPassword: TEdit;
    edtDatabasName: TEdit;
    btnClose: TButton;
    chkvstEnable: TCheckBox;
    procedure btnCloseClick(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  frmSettings: TfrmSettings;

implementation

uses
  frmMainU;

{$R *.dfm}

procedure TfrmSettings.btnCloseClick(Sender: TObject);
begin
  Close;
end;

procedure TfrmSettings.FormCreate(Sender: TObject);
var
  ini: TInifile;
begin
  ini := TIniFile.Create('settings.ini');
  try
    edtPassword.Text := ini.ReadString('Database', 'password', '');
    edtDatabasName.Text := ini.ReadString('Database', 'name', '');
    chkvstEnable.Checked := ini.ReadBool('VST', 'enable', true);
  finally
    ini.Free;
  end;
end;

procedure TfrmSettings.FormDestroy(Sender: TObject);
var
  ini: TInifile;
begin
  database.databaseName := edtDatabasName.Text;
  database.databasePassword := edtPassword.Text;
  frmMain.vst.Enabled := chkvstEnable.Checked;

  ini := TIniFile.Create('settings.ini');
  try
    ini.WriteString('Database', 'password', edtPassword.Text);
    ini.WriteString('Database', 'name', edtDatabasName.Text);
    ini.WriteBool('VST', 'enable', chkvstEnable.Checked);
  finally
    ini.Free;
  end;
end;

end.

DatabaseU:

Delphi-Quellcode:

unit DatabaseU;

interface

type
  TMyDatabase = class(TObject)
  private
    FDatabaseName: string;
    FDatabasePassword: string;
  public
    property databaseName: string read FDatabaseName write FDatabaseName;
    property databasePassword: string read FDatabasePassword write FDatabasePassword;
  end;

implementation

end.
