Re: 4D Server Hosting - The Future ?

Peter, I am in the process of moving a database from our own hardware to and AWS instance. It's true that the most expensive part of setting it up, at this point, is getting the appropriate amount of band width and throughput speed. The other thing about VM vs metal is the whole pre-emptive

Re: File Decoding: EBCDIC

Hi Bob, This was an interesting topic to look up. That data must be coming from a company running some very old main frame. If you haven't already looked at the Wikipedia entry for EBCDIC it's both informative (this goes straight back to punch cards) and humorous.

Re: Web aficionados - Not allow user to access file directly

Hey Randy, The optimal way to achieve this is to set up the website with a different web server functioning as the node publicly exposed to the internet. That server deals with all the authentication and heavy protection stuff 4D isn't very good at and communicates with your 4D server via API

Chris, Have a look at these commands: entitySelection.and( ) - intersection entitySelection.or( ) - union entitySelection.minus( ) - difference entitySelection.add( ) entitySelection.minus( ) For working with a listbox like you are I will have two 'versions' of the entity selection: master

Re: 4D Object To BLOB/TEXT/Document

Jorg, JSON Stringify converts an object into plain text. So you can use: TEXT TO DOCUMENT($docPath;JSON Stringify($myobject)) The syntax of Object Tools is very similar to 4D's. Not the object notation part but the basic OB SET and OB get. I have converted lots of methods using my text editor

Re: Shared objects and collections

Hi Jim, I haven't worked with Storage very much because frankly it's a pain and it's slow. I get why it's a pain and has so much overhead. Every single object has to have its own lock/unlock ('locker') mechanism and it works between preemptive processes. So cool for that - no small thing. For me
