HOla, y gracias de antemano.
Estoy desarrollando una aplicacion en la que necesito chequear el nombre de usuario ,password y dominio antes de proseguir con la aplicacion.
El problema es que no consigo que funcione la API logonuser
y realmente no se por que , ya que la declaro bien ( usando API text Viewer) y la llamo bien tambien , o eso creo. Alguien me puede escribir un ejemplo , o explicarme los parametros de esta funcion con detalle a ver si asi descubro que estoy haciendo mal?
Muchas gracias.
