Re: Survey on 4D’s strategy for implementing Preemptive Processing / worker processes

James, when 4D is keeping the Postgres DB updated what mechanism is used? On the same machine, LAN or using a SOAP call that goes over the internet? Thanks, R Sent from my iPhone > On Feb 22, 2017, at 10:23 AM, James Crate via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > 4D pushes data to

Re: Old doesn't work with object fields

while I love discussing feature requests, I also take the pragmatic view that every new feature comes at the cost of an idea delayed if not discarded. so, if anything is already possible with a little bit of creativity, and fulfils the immediate need, I would be ready to accept that, to clear

Yeah, that's an incredibly good idea. I think it would also be very useful for tables as well - being able to manage metadata for a table without creating a special record has been on my wish list for decades now... > On Feb 22, 2017, at 7:12 PM, David Adams via 4D_Tech <4d_tech@lists.4d.com>

Install 4D v15 for Windows client mode usage

I have a customer site with a mix of Windows machines and I need to get the 4D v15.4 app for use in client mode on to each machine. This is not a merged server/client. What's the best way to get the 4D app installed on each machine? The 32-bit installer seems to want to install all of 4D

Hi Jeff, > If ((JSON Stringify($fieldPtr->))#(JSON Stringify(Old($fieldPtr-> This only works if the order of the keys in the object stays the same which may not be true depending on how you change the object. I’ve pasted in a method below that you can use to compare two objects which

Re: Old doesn't work with object fields

Doesn't Modified only work in a form event? So it turns out that Old works fine with an object field, but you can't do an = comparison. I think what I'm going to do is the following: If ((JSON Stringify($fieldPtr->))#(JSON Stringify(Old($fieldPtr-> Seems really inefficient, but it works.

Re: Old doesn't work with object fields

Jeff, I think this is going to track back to a discussion some time ago about trying to compare two c-objects, or JSON, to each other. It turns out to be really tricky. For instance: JSON a: {key1:1234, key2:"abcd"} is that equal to {key2:"abcd", key1:1234} or {key2:"abcd", key1:"1234"}

RE: Why doesn't 4D generate a crash log or report?

It should automatically log something. If on Windows check * The event viewer for a crash event (or any other type of event related to 4D around the same time) * Next to the 4D.exe or 4DServer.exe there may be a DMP file that can be used by 4D Tech Support to obtain more information; this may

Re: Survey on 4D’s strategy for implementing Preemptive Processing / worker processes

It’s not very sophisticated. 4D pushes data to PostgreSQL, or retrieves data from PostgreSQL, based on either user-triggered actions or periodic task execution. At no point does the Rails/PostgreSQL system access 4D. The fact that 4D uses SQL to access the PostgreSQL database has specific

[JPR] Hi Wayne, In fact, there is a solution, suggested by Vincent de Lachaux, the author of 4D SVG Component. You can use the component method SVG_New_textArea, this command does the job, by using a specific tag instead of the CR. Have a look on the 4D SVG documentation, it may help you to
