RE: List Box gotcha - Automatic Row Height

[Timothy Penner via 4D_Tech]

According to doc.4d.com the description of these two manuals are:

* 4D Design Reference:
- Description and guide for using the features and editors found in the 4D 
Design environment (structure, forms, methods, menus, queries, etc.)

* 4D Language Reference:
- Reference manual for the 4D programming language: describes each command and 
keyword, along with its syntax, parameters and code examples.

Based on those descriptions I don’t think this checkbox is supposed to be 
listed in the Language Reference, but would instead it is supposed to be listed 
in the Design Reference.

RE: List Box gotcha - Automatic Row Height

[Timothy Penner via 4D_Tech]

I don’t think the checkbox or property list would be documented in the Language 
manual because the checkbox is not a language item. However, the checkbox does 
correspond to the command LISTBOX SET AUTO ROW HEIGHT which is documented in 
the language manual (because it is a command).

I am pretty sure that non-language items, such as the GUI or other UI related 
properties, would be documented in the Design manual, not the language manual.

Re: List Box gotcha - Automatic Row Height

[John Baughman via 4D_Tech]

Thanks Tim, but those reference are to documentation of the command SET LIST 
AUTO ROW HEIGHT. I am concerned about the Property List check box which has no 
such warnings, either in the Property List itself or in the LRM. 

It’s very easy to check that box during development, intentionally or not, and 
not know it disables the entire list box until you actually run the db without 
your developer license.

Re: List Box gotcha - Automatic Row Height

[John Baughman via 4D_Tech]

OK, it should still be in the LRM. I rarely go to the DRM and in this case I 
wouldn’t even think to go to the LRM. I wonder how many long time developers 
even are aware that this checkbox has been added to the list box property list 
let alone that it would completely shut down the list box. I didn’t and must 
have accidentally checked it. Not a good situation. 

I just posted the following in the Feature Request section of the 4D Forum…

———
This new List Box property requires a 4D View Pro license. If the license is 
absent with this box checked the List Box is renedered completely unusable when 
deployed. The developer does not have a clue that there is anything amiss as 
the Developer License includes 4D View Pro. It is very easy to inadvertantly 
check this check box and not discover the problem until deploying to a client 
that does not use 4D View Pro.

 If this will remain as standard behavior, the check box needs better 
documentaion. This constraint is mentioned in the Design Reference manual and 
is hinted to in the 4D View Pro Reference. There is nothing in the Language 
Reference Manual nor anything in the Property List that warns the designer. It 
is requested that one or all of the following be implemented.

1. Document the requirement in the Language Reference Manual.

2. Change the Property List annotation to read "Automatic Row Height (requires 
4D View Pro license)

4. Throw an alert saying "4D View Pro licese required if checked"

5. Change the behaviour when the check box is checked and the proper license is 
not present. Instead of disabling the entire list box, just disable the 
Automatic Row Height feature.

Sending Email To FastMail

[Cannon Smith via 4D_Tech]

Is anyone using 4D to send email through a FastMail account? I just switched an 
email address to FastMail and think I have things set up in 4D to send to it 
through the smtp server, but it isn’t working. Using WireShark I can see it 
connects to the server on the TCP level, but that’s about all that happens 
until it times out. I’m wondering if there are any tricks I’m missing.

Thanks.

That’s an interesting approach. I will mentally bookmark it for future use

At the moment I’m using “Selection to JSON” to dump the data into a text 
variable and then SAVE VARIABLES to out it to disk. This is an absolutely 
awsome way to do it I’ve discovered if you’re migrating between heterogeneous 
table structures because you basically have the table at the other end in an 
object array where each source record is accessible at field level by name

Re: Execute on server gotcha

[Janet Jonas via 4D_Tech]

I read the documentation, and that is why I do what I do, I was just trying to 
note it for the list. 

However, being able to delete from a selection created after a READ ONLY(*) 
command is not according to the documentation, but it “works” for me in 
practice. I find it handy, but counter to expectations. I prevent that from 
happening in my application for the regular user.

Anyway, a little off of the original topic.

Re: Execute on server gotcha

[Kirk Brooks via 4D_Tech]

Hi Chip,
Correct I believe. Looking at the chart:

http://doc.4d.com/4Dv16R4/4D/16-R4/4D-Server-Sets-and-
Named-Selections.300-3423889.en.html

not only is the $test set local to the client machine but the <>test set is
too - they differ in scope on the client machine's processes. But the
'regular' test set's scope (as I should think of it) is both the client
machine and the twinned process on the server.

That's probably by design within 4D I'm guessing. I always looked at that
chart as specifically referring to triggers but now I know it's accurate
for sets and named selections as well. Which is a pretty cool feature I
haven't taken much advantage of.

Hi Janet,
The point about unloading the records is a good one.
Have you see this recent tip in the KB:  http://kb.4d.com/assetid=77893

Looking at some of my methods that run EOS my biggest issue is the
assumption I was in READ ONLY when in fact it was READ WRITE.

I like the suggestion Miyako made about testing the method execution
attribute at the top of the method. I could couple that with a test of the
application type to indicate indicate when a method intended to run EOS is
actually running in single user.

RE: List Box gotcha - Automatic Row Height

It's also documented in the Design Reference under 'List Boxes / List Box 
specific properties':
http://livedoc.4d.com/4Dv16-R5/help/Title/en/page3205.html#3510338
{
Automatic Row Height

4D View Pro only: This feature requires a 4D View Pro license. For more 
information, refer to 4D View Pro Reference.

The Automatic Row Height property is only available for array-based, 
non-hierarchical list boxes. The property is unchecked by default. When you 
check it, the Min Row Height and Max Row Height options are displayed instead 
of Row Height and Row Height Array options (see above).

Ref: Resize SVG_Use

[truegold via 4D_Tech]

Hi Miyako,

I think if the image size were uniform in the document I could do that. But the 
same images can be size to different sizes in different parts of the svg doc.

I might just decide to keep things as they were and laid an image as I need it. 
The worst case is that the same image is loaded many times and I cannot use 
SVG_USE.

Thanks,
John...

Re: Execute on server gotcha

[Chip Scheide via 4D_Tech]

clarification please.

if the set created on the client side is "$Test" then it is NOT 
available in the trigger/EOS correct?

Nice -
so.. you don't have and don't use 4D View pro so no reason to examine 
the docs...

Could be unnecessary, it depends on what code, for example:
  while(not(end of selection))
...
  next record
  end while
  unload record  // >>> useless as end of selection means no current record
This is just to illustrate, but such redundant instruction can result in bad 
performances on WAN usage and/or a lot of clients connected. 

Speaking about read only, I learned this particularity of ARRAY TO SELECTION 
last year: 
"Note: Since it can create new records, this command does not take a table's 
read-only state (if any) into account"
