Anytime an internet functions fails, check it for the error.

   HINTERNET handle_Session = InternetOpen("My App",
   if( NULL == handle_Session )
   {	FunctionThatReports_InternetGetLastResponseInfo("OpenError");
   }else{
	handle_Connect = InternetConnect(handle_Session,
	if( NULL == handle_Connect )

{FunctionThatReports_InternetGetLastResponseInfo("ConnectError");
	}else{


void  FunctionThatReports_InternetGetLastResponseInfo(char*where)
{    char		lpBuffer[8*1024];
     DWORD	Err = GetLastError();
     DWORD	Llp = 8*1024;

     if( Err < INTERNET_ERROR_BASE )
     {    sprintf( lpBuffer, "Standard Windows Error Number %i", Err);
     }else
     if( Err == ERROR_INTERNET_EXTENDED_ERROR )
     {	InternetGetLastResponseInfo( &Err, lpBuffer, &Llp);
     }else
     {	sprintf(lpBuffer,"Standard.Internet.Error.Number.%i",Err);
     };

MessageBox(hWnd,lpBuffer,where,MB_OK|MB_ICONINFORMATION|MB_TOPMOST);
}

Might be wrong, Mine is
    if( NULL != (hInternetSession = InternetOpen(
                      "Microsoft Internet Explorer",   // agent
                      INTERNET_OPEN_TYPE_PROXY,        // access
                      "ftp-gw",                        // proxy server
                      NULL,                            // defaults
    	  0)) )                              // synchronous

hFTPSession = InternetConnect(
	hInternetSession,
	"ftp.halvani.de",	//make sure this is correct
	INTERNET_INVALID_PORT_NUMBER,
	name,		// make sure this is correct.
	pass,		// make sure this is the correct password
	INTERNET_SERVICE_FTP,
	0,
	(DWORD)0);

You might also want to change your TRUE to FALSE.

     bResult = FtpGetFile(
	hFTPSession,        // Handle from an InternetConnect call
	from,to,
	FALSE,				// always copy
	FILE_ATTRIBUTE_NORMAL,
	FTP_TRANSFER_TYPE_BINARY,	// exact copy
	0/*context*/);
