FileAttachments.Win - Introduce a capability to implement a custom algorithm to open an attachment with the help of some application

Hello,
The "WindowsForms File Attachments" module allows an end-user to open an attachment with the help of a default program, which is registered in the operating system for this sort of files (by a file extension).
This module saves its content into a file within a system 'TEMP' folder and passes it to the operating system to open. Then the Operating System searches for a default program and starts it.
Then, the module doesn't handle the file that has been created (in other words, doesn't delete it), because it cannot determine when a file becomes unnecessary.
For more details, see:
- "A 'File cannot be found' error occurs when trying to open a file from the 'FileAttachmentPropertyEditor' or with the help of the 'Open' action" at http://www.devexpress.com/issue=B97246
- "Can't open some filetypes with FileDataEdit control" at http://www.devexpress.com/issue=B97047
Now, the "WindowsForms File Attachments" module contains the "CustomOpenFileWithDefaultProgram" and "CustomSaveFiles" events, which allow you to manually open a selected attachment with the help of some program, or to manually save it into a file.
Thanks,
Dan
