I have written static function and i am calling UpdateData() from this static function. It's giving error - Can't call non-static from static.
What is the solution? Please help me.

Don't use a static function to host code which requires access to per instance state.

In addition to Stephen's answer: static member functions are not 'owned' by a particular instance of a class (they are 'shared' across all instances in fact). So this means they cannot access non-static member functions or variables (because this will require to know with which instance of the class they are dealing, which is impossible).
So, why do you need to have a static function ? Is there a specific reason for that ? I guess that you can simply change it into a non-static one.
If not, then provide more informations.

If you cannot change the static function to and non-static, from where is this static function called? Does it have the HWND of the dialog?

No, it doesn't have the HWND of the dialog.
Anyway I have converted from static to non-static. It is working.
Thank you very much for the help.

there is no such function exist in Unmanaged VC++. you have to implement the logic urself for same, i.e. you have to create directory on remote servers ( CFtpConnection::CreateDirectory) and using CFtpConnection::PutFile you can recursivly put file on remote server!

i tried the same but what happens is the file copies separately in the same place where the new folder created not inside the created folder.
pConnect = sess.GetFtpConnection(m_host,
m_user,m_pswd,atoi(m_port),false);
CFtpFileFind finder(pConnect);
pConnect->CreateDirectory("sample");
BOOL bWorking = finder.FindFile(_T("*"));
strFileName += m_host;
strFileName += finder.GetRoot();
MessageBox(strFileName);
BOOL bUploaded = pConnect->PutFile("C:/070206_NewVExls.xls",
"ss",FTP_TRANSFER_TYPE_BINARY,1);
if(bUploaded==0)
MessageBox("unsucess");

You need to change directory on the remote server, otherwise it won't know you need to put the files in a different place. FTP does not stand for File Transfer (Psychic).

Please give Folder path as argument instead of string "SS"

hi,
i also facing the same problem, how i can connect to the FTP Server and also get the file and save the file in server??
is the connection using CFtpConnection? and where can i get the references...
have a nice day

You can see this here[^] and also see example ftp in MSDN
|
|
|
|

is message queue will be per process or thread or System???
|
|
|
|
|
Per thread; but it's created on demand so not all threads will have one.

if it is per thread, then why we need handle in MSG structure???

I assume you're referring to the hwnd HWND in the struct. We need this because, regardless of any threading issues, we still need to know which window the message is for.
From MSDN on GetMessage
"The GetMessage function retrieves a message from the calling thread's message queue."

Exactly what you want to know?
