Object RFUSRAPP (DOS legacy)

Description

Download and run local application programs in the WS Client (DOS Only).
This feature allows to run programs locally (without RF connection) to capture data, and later upload the data to the host through RF network.
The local programs are downloaded form the Host PC into the PDT's volatile RAM disk (D:\USRAPP) and then save them into the permanent FLASH disk (E:\USRAPP) to be stored and to run them.
Saving and/or running local applications requires closing the current WS Server connection, exiting the WS Client program, saving the last downloaded files (if necessary) and launching the local applications.
Application data needed by local applications should be downloaded and uploaded from/to host by the RFTransferFile method of the RFFILE object.

Application files may be updated (downloaded only if relevant) from a source folder. A utility configurable demo program is shipped with the server.

Local application filenames in the client will be retrieved by the RF application.
The filenames, date, time and size are stored in an array to be accessed by the user application.
