  borderStyle: Ti.UI.INPUT_BORDERSTYLE_ROUNDED,
  passwordMask: true,
  value: password,
  top: '14%', 
  left: '35%',
  width: '60%', 
  height: 30
});
winConfig.add( textPassword );
var lblstatus = Titanium.UI.createLabel({
 top: '45%',
    text: "...",
    color: color_barra,
    font: {fontSize:14,fontFamily:fuente_general},
    textAlign:'center',
    width:'90%',
    height: 'auto'
});
winConfig.add( lblstatus );
var btnLogin = Titanium.UI.createButton({
   title: 'Conectar',
   top: '25%',
   width: '90%',
