SoftArtisans Xfile

New in V2.4.1
Issue resolved:

• XFile version 2.4.0 did not send the custom X-Content-Length header required by FileUpEE for chunked uploads
• Browser crashed when accessing certain parts of the XFResume object
• Downloads over 4 GB with the visual control terminated before completion

New in V2.4.0
Issue resolved:

• Security fixes for buffer overflow vulnerabilities
• Error: "Could not create RequestRecord" with resumable uploads and downloads
• IE crashed when calling AddFormElement
• Visual control and client-side progress indicator displayed incorrect size for files over 2 GB
• Browser crashes during downloads
• "Error: Source=null Description=null" masked true error
• Large chunked 3-tier uploads failed
• FileManager: Attributes property of File object was not working correctly
• Filemanager: DeleteFolder method could not delete sub-folder

New in V2.3.4
New Features:

• Resumable uploads can now be done asynchronously. Previously, the Start method had an asynchronous option, but the Resume method did not*
• TopFolder property now creates directory structure for storing resume info if the directories do not exist*
• XFResume.IsOpen method was added to determine if the object is already open to a location*

*Available only in XFile Enterprise Edition

Issue Resolved:

• Errors downloading files with long URL using the visual download control
• Because of 2 GB limit in ASP.NET's maxRequestLength setting, XFile's threshold was lowered from 4 GB to 2 GB for automatically switching uploads to chunked transfer encoding and the custom HTTP client. (equivalent of setting oXFRequest.TransferEncoding = 1 and oXFRequest.UseWininet = false)
• Certain cases were causing an "Operation timed out" even though no timeout occurred
• TransferStatusChanged event did not return TransferCancelled status when user aborted the transfer
• TransferStatusChanged event did not return TransferTimedOut status after client-side timeout
• When SaveLocationPromptType set to 2, hitting cancel in the save dialog caused browser crash
• When SaveLocationPromptType set to 1, hitting cancel in the folder dialog caused browser hang
• If user cancelled uploads and TransferStatusChanged events were being handled, browser would sometimes crash
• Chunked-encoded uploads caused erroneous timeout error
• Files uploaded or downloaded with the visual objects did not appear "checked" if the upload completed through a resume operation
• Calling RemoveAll on the visual upload and download controls did not remove files from the underlying file collection of the XFRequest object
• Setting client-side timeout value to 0 caused browser freezing
• Error thrown when xfclient.dll not registered referred to incorrect dll name
• Buffer overrun in SSL transfers caused browser crash
• Issue with XFResume.Close prevented the XFResume object from being reopened*
• XFile returned non-JobId folders when checking ResumeInfo collection*

*XFile Enterprise Edition only

New in V2.2.3
New Features:

• Added new methods to sync events when XFile is run in scripting or VBA environments
• New Event for the XFRequest object: OnStatusChange

Issue Resolved:

• Changed the way cached headers were being added to the Resumed Request
• When not using WinInet, sometimes Response headers were being lost
• In some cases, chunked-transfer encoded downloads were not being correctly interpreted as failures

New in V2.1.7
Issue Resolved:

• Renamed WebClnt.Dll to XFClient.dll due to a naming conflict with a Windows XP dll
• Under certain circumstances, the Request Record for resumable downloads would not be updated, resulting in the same file being concatenated with itself
• In some cases, a DNS or Unresolvable Host error would return a Response Status of 0 and would not throw an exception

New in V2.1.6
Issue Resolved:

• Under some circumstances, authentication did not work

New in V2.1.5
Issues Resolved:

• On Windows 95/98/ME, using the Visual Upload Control (AXFFile) caused IE to crash intermittently
• The Add File Selector for the Visual Upload Control (AXFFile) on some foreign versions of Windows did not render correctly
• Some file view types (for the Add Files Selector) did not work on Windows XP
• When forcing a multipart/form-data request that does not contain files, an extra CRLF appeared after the last form element
• An error occurred when setting DiscardResponse to true when using the Visual Download Control (AXFFileDownload)

New in V2.1.4
Issue Resolved:

• The download folder selection dialog was missing the folder list view when used asynchronously

New in V2.1.3
New Features:

• Customize column headings for the upload and download visual controls.
• New Property: FileNameColumnWidth = 0 - 100. This is the percentage of the width of the list view. Also, setting AXFFileDownload.HideURL to false now sets the width of the URL column to 0 or this property to 100.
• Ability to disable the animated gif image in the progress indicator.
• OpenAfterDownload functionality is now customizable.
• New Property OpenAfterDownloadIndex on the XFrequest object. Possible values and their meaning:
• o 0: Open all files until the first error occurs, default for backwards compatibility
• o -1: Open all files, unless an error occurs for that file
• o i: Open only the specified index (1-based)
• New method OpenInApplication() on the XFFile object. This can be used in conjunction with the DownloadError object to open files after download.
• Ability to use our visual progress indicator with a non-visual file transfer: added the XFRequestStream property to the XFRequest object.
• Added better control of File Selector (part of AXFFile). The following new properties and methods have been added:
• o FileViewType = SAFileViewType. The default is List. SAFileViewType { LargeIcons = 0, SmallIcons = 1 List = 2, Details = 3, Thumbnails = 4 }
• o FileSelectorWidth = 400 - 1200 pixels
• o FileSelectorHeight = 200 - 800 pixels
• o AddFileSelectorFilter(FilterDescription, FilterPattern) Description: The FilterDescription is a display string that describes the filter (for example, "Text Files"), and the FilterPattern specifies the pattern (for example, "*.TXT", "*.*", "a*.*", "*the*.*"). To specify multiple FilterPatterns for a single display string, use a semicolon to separate the patterns (for example, "*.TXT;*.DOC;*.BAK"). A pattern string can be a combination of valid file name characters and the asterisk (*) wildcard character. Do not include spaces in the pattern string.
• o ClearFileSelectorFilters Description: Clears all filters. The dialog will use "All Files (*.*)"
• New Property: IsActive, used when XFile is executed asynchronously to determine if XFile is transferring a file or is capable of starting another transfer.

Issues Addressed:

• When using XFile asynchronously the internal mime composer was being reset prematurely.
• File selection dialog flickered.
• Canceled property always returned True after Start() returned.

New in V2.0.3
Issues Addressed:

• When setting the property UseWinninet=False, multiple download requests will fail after the first one.

New in V2.0.2
Issues Addressed:

• Canceling a transfer when using WinInet was causing a "can't create file" exception and/or crashing IE.
• URLEncoding failed on some special characters.
