Tim, I'm glad you reminded me of this one. I don't have problems with sending emails so much but the process for downloading them caused problems. I actually split that process off into a separate database - the downloads get processed into a watched folder. One of my first thoughts was to split

Re: Tags in record on 4d.

I'll just add you don't actually need to put the keywords in a separate table anymore. You can add a text field to your table. Populate the field with the keywords (or tags) using a space as the delimiter. Then set that field to have a keyword index and query it using the keyword operator. I've

Re: How to trap a form save keystroke in an object method ?

Peter, How about adding a hidden button to trap for Enter key strokes? I run all my active objects into a single project method (the 'form controller' I like to talk about). So I'd have that button call the form controller and handle the save code the same way the normal save event would process.

Re: Exploring CALL WORKER vs New process

Keith, First off I'm not clear what the intent of wOpen is - are we modifying the record or simply displaying it? If it's only being displayed you don't need CALL WORKER to change it - any process that can load it can change it. The issue becomes notifying the display process to refresh itself -

David, Thanks for throwing this in. It really does make more sense to use a longint even if it is (currently) only a binary choice. On Fri, May 12, 2017 at 6:03 PM, David Adams via 4D_Tech < 4d_tech@lists.4d.com> wrote: > Just as a simple point, it's nice to have access values as a number: > > 1

Right - so the ultimate permission is the most permissive of all available. On Fri, May 12, 2017 at 4:56 PM, Alan Chan via 4D_Tech <4d_tech@lists.4d.com > wrote: > I assume a member might belongs to multiple teams but will a member > belongs to multiple clubs? > > Alan Chan > > 4D iNug Technical

Re: Schemes for record level access control

Hi Alan, Those are the go-to solutions. In my case we aren't using the 4D password system so I can't rely on that. Plus I need actual record level restriction. So to follow your example, I may want a Team to be able to see themselves and other teams in their Club (just making this up) but not

Schemes for record level access control

Hi folks, I'd like to hear from some of you who have implemented systems that allow for record-level access control in a 4D database. This is the sort of thing where we want to prevent unauthorized users from seeing or inferring the 'restricted' records. Theoretically it's pretty easy - include a

Re: Problems with LISTBOX SET FOOTER CALCULATION and dynamic columns (v15)

Hey Lahav, You are correct - thanks for saying something. It prompted me to go look at my actual code which is pretty similar: get the current doc values obj $obj:=JSON Parse("{}") $obj:=IG_get_curDocValues ($igPtr) For ($i;1;Size of array(aIG_ftrVars)) OBJECT SET RGB

Re: Problems with LISTBOX SET FOOTER CALCULATION and dynamic columns (v15)

Hi Olivier, It's so interesting when someone follows up on a post from a year and a half ago. I haven't used this code in v16 yet. But in general what I've found most reliable when fiddling with dynamic variables and listboxes is to let 4D tell you what it did by using the LISTBOX GET ARRAYS

[OFF] I need an OAuth tutor

I have a project that requires having 4D connect via OAuth. I know this totally doable but I just keep getting stuck. So, I'd like to hire someone who knows this stuff to tutor me for an hour or two. I'm thinking we do a Teamviewer session or similar. Contact me off line if you're interested.
