hello youtube same here from YouTube dot
com slash
on live gamer for the New Boston in this
tutorial
really continue working on our FTP
download
now FTP stage for file transfer protocol
in nineteen
that I'm so here is my project directory
for the FTP download it's in documents
Visual Studio 2010
projects in the FTP download your
YouTube now
you have all these files here except for
FTP client VB
dot DL now I had topped to
lucky yet but I'm gonna see if he will
with this
DLL file in the download this is a class
library
has a bunch stuff that we can use with
FTP
now this is created by a guy named
Howard re Howard Richards on he
is a programmer for
the he posts at the Code Project a lot
and now I'm not advertising for the Code
Project and X
I don't actually use it myself I just
want to give full credit to Howard
Richard
working in this class library that we
can use so go ahead
and members know that here is FTP client
BB
now at the moment we can't do anything
with this DLL file
so what we can do is over a program
called
I L spy I'll spiders is Wes
decompile dot net programs and class
libraries
now nothing you guys a download link for
this one
you can search for Google yourself
and/or gonna do
Israel file open and let's just go ahead
ago to documents Visual Studio
2010 projects and with you
FTP download you too years FTP client BB
dot DL and you see we can
open this and opens up this I'm
right here in power menu
in its art class library secrecy has
references which we don't need to look
at it has resources
which we don't need to look at it here's
where all the clothing store
so let's go to
utilities dot FTP so here is
FTP client now we can go ahead
and look and see was he has created for
us to use
so we got ftp file exists now
it's a billion in returns to check and
see if an ftp file exists and takes a
string argument which is a file name
now you may be thinking what is all this
type tonight here this is not
basic this is other language
well this was written in C sharp if you
create a craft
class library in C sharp because the
shop on the dotnet framework you can
also use that
class library with Visual Basic programs
in the same
issue the other way around so if you go
to class I very in Visual Basic
I believe you can go use it with
chartres so
on this is a whole bunch that the it is
sexy the FTP file exists
and if it does its gonna return true
and and if it does it'll return false we
can rename
FTP files weekend the lead directories
we can do a whole one sister that Howard
Richards has at it for us
which makes it very easy to work with
the File Transfer Protocol so go ahead
and close out at that so now we need to
do
is we come into you are FTP download 32
project will you come up here
and we need to add a reference so
with your project at reference
and less just browse saga
FTP download YouTube right here and if
you just click this button right here
up one level you can see we have FTP
client BB dot DL
and you can see that this X Estadio
files so it's like FTP client BB that
deal go ahead and click okay and you can
see that
it bad a reference in our project
now nothing really changed so what we
can do is come up here
click show of files and we can go up to
references
NXE that we have FTP client BB
under our references which is a class
library
down let's go ahead and give it a show
of files so
in this is real I want you guys to and
d compiling our class library with I'll
spy so we can see a little bit about
what it does
and how it helps issues File Transfer
Protocol
and then we headed a reference to do
that class library
so the next to it when you start using
that class library
to you do stuff like up their server
open folders
and other stuff that we have already
added on our gurl
so thanks for watching and stay tuned
