Re: v17 conundrum in design

I worked on a project that did this too. In that case it turned out to be an error in some old ALP code. Something subtle like a mistyped variable. You may have a component or plugin that's generating the error silently. On Thu, Feb 7, 2019 at 12:52 PM Chuck Miller via 4D_Tech <

Re: Set Time question

Just to add a little more to this. I suspect a number of readers already realized a really simple solution to this specific case is to simply test the read/write state in the On timer form event and NOT update if it's read write. This turns out to be a better solution in my case because it's a

Set Time question

Hi List, I have never used Set timer very much so I've got a noobie question. I'm adding some real-time updating code to financial forms: think Invoices, Billing Account summaries. that sort of thing. An invoice is the most obvious - User A has a form open that displays the invoice details (total

Re: How to display read-only input form

Jim, If the table is in read only mode you can use any form you want and the user can't edit the data. I'd just put the table in read only and use DIALOG with the input form. On Wed, Feb 6, 2019 at 1:32 PM Jim Crate via 4D_Tech <4d_tech@lists.4d.com> wrote: > Is there a convenient way to mimic

Re: call subform

Chuck, If AddButton is on the subform you don't need CALL SUBFORM CONTAINER at all. Just handle it there in your subform code: OBJECT SET VISIBLE(*;"AddButton";Not(Read only state([table]))) I would put that in the form method code (i'm talking about the actual form you use as the subform) so

Re: listbox commands and collection variables

Hey John, I'm not able to replicate all of the issues you mention with a collection based listbox. To test I made a form and added a collection based listbox with two columns. To open it I made a method, created a collection with 10 elements comprised of objects and had the listbox displace the

Re: Postal Addresses by City

Walt, Are looking for the actual addresses? There are companies that sell those sort of lists. I haven't looked in years... This one is top of the list: https://www.infousa.com/lists/zip-code-mailing-lists/ Or do they have addresses and want to verify them? For that I have been using Smarty

Re: Socket Communication

That looks pretty cool. I've built a chat app on PubNub a while ago. ( www.pubnub.com) I haven't looked back at PubNub recently - Pusher looks like they may have built out a few more tools. In both cases they have very generous free programs. On Tue, Jan 15, 2019 at 1:57 PM Welsh Harris via
