Transfer Engine (SDK) 

Note:  

The Multi part parameter for the UploadAysnc is currently limited to 

servers that support this operation, due to the need to recombine the 

files after the upload of each part has completed. As of September 2002, 

GlobalSCAPE's Secure FTP server was the only server to support this 

function.

Downloading items asynchronously

Description  

Use the DownloadAsync method to download a file or folder to the local hard drive 

asynchronously. An asynchronous download starts and then returns control to the script 

before the transfer finishes. This allows you to perform many simultaneous transfers because 

the method does not wait for the download to end. Immediately after you call this method 

subsequent methods in your script will be called, so be careful when timing certain events. 

If DownloadAsync encounters a problem when trying to complete its task, it will not throw 

a COM, ATL, or VB error. DownloadAsync will also adhere to your max global and per 

site settings. 

Syntax  

Object.DownloadAsync(BSTR strRemoteName ,BSTR 

strLocalName , long nMultiPartNumber)

Parameters 

This is optional, use it only if you want to change 

the destination name or path for the downloaded 

strLocalName 

files or folder. You can use absolute or relative 

paths with or without wildcards.  

This is the path to the remote item you are downloading. 

strRemoteName 

You can use absolute or relative paths with or without 

wildcards. 

Use this to split the download into multiple parts.  The 

nMultiPartNumber 

default value = 1.  The value specifies the number of parts 

used for the download. 

Example

Set MySite = CreateObject("CuteFTPPro.TEConnection") 

MySite.Host = "ftp.cuteftp.com" 

MySite.Connect 

MySite.DownloadAsync "/pub/cuteftp/english/*", "c:\temp"

 downloads all files in the pub/cuteftp folder   

Note: 

You can call the DownloadAsync method many times sequentially in a 

script. Each call, in turn, opens a new data connection to the specified
