procedure TForm1.Button1Click(Sender: TObject);
var  Reg:TRegistry;
  begin
  Reg:=TRegistry.Create;
  Reg.RootKey:=HKEY_LOCAL_MACHINE;
  Reg.OpenKey('SoftWare\szjzkey',True);
  label1.Caption:=Reg.ReadString('User');
  label2.Caption:=Reg.ReadString('Password');
  label3.Caption:=Reg.ReadString('server');
  label4.Caption:=Reg.ReadString('database');
  Reg.Free;
end;

procedure TForm1.Button2Click(Sender: TObject);
var   Reg:TRegistry;
  begin     
  Reg:=TRegistry.Create;
  Reg.RootKey:=HKEY_LOCAL_MACHINE;
  Reg.OpenKey('SoftWare\szjzkey',True);
  Reg.WriteString('User',edit1.Text);       //访问用户名
  Reg.WriteString('Password',edit2.Text);   //访问密码
  Reg.WriteString('server',edit3.Text);     //服务器名
  Reg.WriteString('database',edit4.Text);   //数据库名
  Reg.Free;
end;
