Maybe too simple for what you need to do, but have a look at the "execute on server" property for project methods.
Create a method that is executed on server. It gets as $1 the id of the document you want to display on the client side. The method does everything to fetch the document from the directory on the server etc. and sends it to the client in $0. Keep in mind that this method (executed on server) behaves similar to a trigger method: you are read/write for all tables and you should have your own On Err Call method.

April 2020 10:57 An: 4D iNUG Technical <[email protected]> Cc: Chris Belanger <[email protected]> Betreff: 4D v18 — Need methodology to I have a methodology of allowing clients to transfer documents that are thereafter stored by 4D Server in a ‘LIBRARY’ of system documents it maintains automatically. [these are not stored in the DB, but in a managed folder on disk.] I do this by: • Loading a system document into a BLOB, then using BASE64 ENCODE to store it in a TEXT field; —— thanks Peter Bozek for the tip on BASE64 ENCODE / DECODE! • the TRIGGER method (running on 4D server) unpacks it and creates / updates the files in its ‘Library’ directory on disk. Now I need to be able to retrieve the contents of these files for 4D [Client]. I can display the files in a Web Area —> Thanks to Keith for the tip. ** But I am looking for a simple way to get 4D Server to ’send’ the data to the CLIENT (4D) upon request. In the past [since v12), I made elaborate ‘communicator’ stored routines to fudge it, but I have a feeling that now there are better ways to do it. I wish it was simple as: Request_Document ( $LibraryEntity ) —> Document Contents [retrieved from the library of user’s documents stored by 4D Server on disk] Any suggestions? Do I have to use Workers, or Stored Procedures, or something?
