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"

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???
