hola, estoy haciendo un programa que sube archivos a un FTP.
El caso es que me gustaría implementarle una barra de progreso, para cuando sube un archivo pesado, saber elporcentaje que lleva subido.
Bueno, la idea que tenía era:
peso del archivo - (peso del archivo / datos transmitidos)
me daria el porcentaje transmitido del archivo. es decir, el progreso.
Lo que no se hallar es la cantidad de datos que he subido ya, es deicr los datos transmitidos.
Cómo puedo saber el tamaño que ya he subido??
Muchas gracias.
Elcódigo que uso es el siguiente:
