B4A Library Automated FTP Library

New Automated FTP Library


UPDATED 3-24-2014 - Version 1.06 changes the display scale and should look better on the larger display of a tablet. A sample project is now included which shows how to use this library. The sample code requires B4A 3.2+. You can open and view the code with older versions but it will not run because of the newer layout files.


UPDATED 1-24-2014 - Version 1.05 adds a new function for checking for files or folders. It also contains a few other small fixes.
The new command works for Files or Folders. If the last parameter is set to TRUE, it will look for folders, if the last parameter is set to FALSE it will look for files. Because the code runs in the background and is modeless you must have a callback sub in the calling module. Code samples below:

B4X:
'Call the command like this:
FTP.FileOrFolderExist("plane.jpg" , "test/files", False)

B4X:
'Callback sub in calling module:
Sub FTP_FileExist(Found As Boolean)
    If Found Then Log("True") Else Log("False")
End Sub

UPDATED 4-2-2013 - Version 1.02 Corrects an issue where PassiveMode was not working and also corrects an issue where UploadFileSet would not work from File.DirInternal.

Automates the process of sending and receiving files using FTP with Wildcards & File Masks. Version 1.02 is attached. Please post/report back any issues you find, etc.

This library has progress bars for Each File and overall progress. It handles wildcards and multi file types at the same time. Issue one command and transfer multiple files and multiple types! Change the colors, text size and words of all objects on the Progress Dialog to fit the look of your app. Also works in Stealth Mode!

REQUIRES: B4A 2.5 +
Copy the FTP_Auto.jar & FTP_Auto.xml files to the Extra Libraries folder.
