    Dear developers,

    Quasidata announces version 1.4 of Transfer@Once, a component set designed
    to extend VCL components with full-blown clipboard and drag-and-drop
    capabilities. 

    ----
WHAT'S NEW?
- TtaoOleObject controller component transfers OLE objects to other
applications.
- TtaoController.Perform method to manage the controller.
- Added support for Mozilla 1.x/Firefox 0.x in TtaoInURL.
- New format components:
 - TtaoInFileContentsW accepts items from Windows XP Compound Folders and
other applications as virtual files.
 - TtaoOutFileDescriptor, TtaoOutFileDescriptorW, and TtaoOutFileContents
supply data to Windows Explorer or another application as if it were a file.
- New demos:
 - Demo project OleObject demonstrates how to use TtaoOleObject and how to
use the Perform method to manage the controller in case if no visual control
is associated with it.
 - Demo project ExtractFile demonstrates how to create in Windows Explorer a
file extracted from an archive or a database.

AT A GLANCE.
Many applications allow users to transfer data to another application by
dragging and dropping the data with the mouse, or by using the clipboard.
With Transfer@once to build applications that transfer data both ways is now
so easy as put a component on a form. Now you can get external drag-and-drop
operations managed by OLE to work through the same events as internal ones
managed by the VCL.
Right now you can accept data as BIFF5 (supported by MS Access), BIFF8
(native to MS Excel), file names and Shell items (native to Windows
Explorer, Desktop), virtual files (supported by MS Outlook, Outlook
Express), hyperlinks (native to Internet Explorer/Outlook/Outlook Express,
Mozilla/Firefox, and Netscape Navigator; Opera does not support the
feature), Internet shortcuts (native to Windows Explorer and Desktop), and
Text/Unicode Text (supported by everything).
You can supply data as RTF (native to MS Word and WordPad), BIFF8 (native to
MS Excel), tabular text (supported by MS Access), file names and Shell items
(native to Windows Explorer, Desktop, supported by Delphi/C++Builder IDE),
hyperlinks (native to Internet Explorer, Mozilla/Firefox, and Netscape
Navigator; Opera does not support the feature), Internet shortcuts (native
to Windows Explorer and Desktop), and Text/Unicode Text (supported by
everything, isn't it?). OLE objects created using Automation can be moved to
external applications.
Transfer@once is a component set that consists of the following components:
- TtaoWinControl is a general-purpose customizable component designed to
work with any visual control. Only a single component is needed to allow a
visual control to support the clipboard as well as drag-and-drop.
- TtaoStringGrid allows TStringGrid to support clipboard and drag-and-drop
data transfer.
- TtaoDbGrid makes a TDBGrid capable to copy and paste records as well as a
single cell. It supports drag-and-drop of a single cell also. If a
TtaoDbGrid component is unable to paste records, it stores them in an
in-memory dataset, so the user is able to fix the problems that resulted in
the paste errors.
- TtaoOleObject transfers OLE objects to other applications.
- TtaoDragCursors replaces the drag cursors predefined in the VCL with the
common Windows drag cursors.
----
The price for Transfer@once 1.4 with complete source code is $69. After
registration you will get free lifetime upgrades and free lifetime support.
