« Respuesta #1 en: 23 Abril 2006, 21:28 pm »

Bueno no se si lo quieras hacer por Vb por que no entendi pero bueno


Ya que tienes tu cuenta en un hosting desde una ventana en windows por "  ftp.nombre.com " si estas en miarroba seria ftp.miarroba.com de ahi entras le das click derecho en iniciar sesion pones tu nombre de usuario contraseña despues copeas y pegas tus archivos que quieres subir y ya estaran en internet.


Bueno no se si era esto lo que buscabas es algo confuso o tu dises desde una aplicacion VB nop entiendo

  bueno si, el codigo que dio saken_c4 funciona pero por ejemplo y coloco este codigo en un formulario con un boton(command1_click) y al presionar el boton envia el archivo al server ftp . ASTA AKI TODO BIEN ;D ;D

  Pero a lo que voy es que cuando intento mandar otro archivo ya no me lo deja mandarlo. La unica forma de poder mandar nuevamente ese archivo es cerrando el formulario(programa) y volviendolo a iniciar por que sera :-( alguien podria decirme una solucion a esto :-( :-( :-( :-( :-( :-( :-( :-(

   ( al presionar una vez el boton)
                 programa==> envia datos al server ftp
  (al presionar por segunda vez el boton)
                 programa==>  no envia el el nuevo dato
  (para que funcione)
                 cierro el programa ==> y alli recien funciona para enviar otros datos pero solo una vex y asi sucesibamente

    FtpBajar = vBool
    InternetCloseHandle hConnection
   
    If EXE = True Then ShellExecute Me.hWnd, "", ArchLocal, "", "", 0
End Function




Las funciones devuelven True o False (dependiendo si se pudo realizar o no la accion deseada).

Un ejemplo para bajar archivos seria:
Código:
MsgBox FtpBajar("200.32.12.4:21", "Mi Usuario", "Mi Contraseña", "Carpeta\Archivo.exe", "C:\Archivo.exe", True)
'El True al final significa que el archivo va a ser ejecutado cuando se termine la descarga

Un ejemplo para subir archivos seria:
Código:
msgbox ftpsubir("200.32.12.4:21","Mi Usuario", "Mi Contrasela", "C:\Archivo.exe", "Carpeta FTP\Archivo.exe")



Espero que te sea de utilidad, saludos.-
