Re: Printing Structure Diagram

Hi,

In QS_Toolbox, I've implemented the Vincent solution.
You can view inside the component the diagram and also export it as picture.

Have a look here: association-qualisoft.eu

Chip,
You should have two licences selected in the Licences tab:

Re: How to connect to a 4d ODBC server across a network

[Tom Benedict via 4D_Tech]

>Is it possible to create a UserDSN or SystemDSN that can find the server
>located across the network??

My experience is a few years old, but you should be able to do this. The 
documentation which comes with the 4D ODBC driver (here’s the link for 4D ODBC 
Driver v17: 4D ODBC  
DRIVERhttps://doc.4d.com/4Dv17/4D/17/4D-ODBC-Driver.100-3786159.en.html
 https://doc.4d.com/4Dv17/4D/17/4D-ODBC-Driver.100-3786159.en.html>) 
describes how to configure the UserDSN or SystemDSN. Take care that you are 
using the correct version, 32-bit or 64 bit. Are you doing this on Windows? If 
so, make sure you’re using the correct 32 or 64 bit version of ODBC Data Source 
Administrator. It might be called Data Sources (ODBC) in Control Panels.

HTH,

Tom Benedict

Hi Chip,

As Chuck points out, did you specify the location of Unlimited Desktop?

That is,
Choose DESIGN -> BUILD APPLICATION.
Select the “Application” tab.
Check-mark “Build stand-alone application”.
Click the ellipsis button (ie, “…”) and select 4D Volume Desktop.
Click BUILD.

RE: How to connect to a 4d ODBC server across a network

[Stephen J. Orth via 4D_Tech]

We have a similar situation, but it's simply because we don't want to have to 
install the ODBC on every Client.

The way I get around this is to separate the SQL query into it's own method, 
and have it run on the Server.  This way there is only 1 ODBC System DSN.

The method packs the results into an Object (JSON format) and returns the 
results back to the Client method, where it is unpacked and displayed to the 
user.

Hope that helps!


Best,


Steve

I am accessing (via an SQL query) my 4D database across a network.
The 4d ODBC database is situated on one server and the software I will be

Is it possible to create a UserDSN or SystemDSN that can find the server

How to connect to a 4d ODBC server across a network

[msherloc via 4D_Tech]

I am accessing (via an SQL query) my 4D database across a network.
The 4d ODBC database is situated on one server and the software I will be
querying the database will be on another server.
Is it possible to create a UserDSN or SystemDSN that can find the server
located across the network??

Not sure how to do his and keen for some advice

Re: Printing Structure Diagram (Somewhat O.T.).

[Jack Stewart via 4D_Tech]

Your email reminds me that I have a whole lot of legacy, 
Macintosh 4D applications software and accompanying manuals 
complete with original 3-ring binders which I would like to 
sell. I used to do a lot of 4D development but have gotten away 
from it in recent years. I stopped purchasing updates in 2003.


This 4D material contains the full gamut of 1990 to 2003 4D 
applications ranging from 4D itself to 4D Write, 4D Draw, 4D 
whatever :) I own it.


I would like to sell it all if there is a market for it. Some 
applications remain unopened and everything is in excellent 
condition. The manuals alone contain a wealth of relational 
database theory and I have lots of 3rd party 4D books as well.


Just wondering if anyone can advise me if there is any demand 
for this material. I would like to see it go to a good use.


Thanks,

Jack

Hi All,

We are in the midst of analyzing a very old 4D application. 
We’d like to print/plot/PDF a structure diagram, in all 
it’s glory, to hang on the wall.  It must represent all 
structure elements such as Tables, Fields, Relations, Indexes, 
etc….  I have seen these diagrams for other platforms but I 
haven’t been successful in extracting such from 4D.
Way back in the day I could print a tiled version of the 
structure from the Structure editor window but that print menu 
seems to be disabled (at least for me) in current versions of 
4D.  Ideally I would like to export the database as xml or 
JASON and load it into another charting specific application to 
manipulate and print.  I just need to find the proper 
application (or 4D component/methods) that can consume the 
xml/JASON and provide the needed diagrams.


An example of what I am hoping for can be found in the top 
image of Vanessa Talbot’s 4D blog entry titled, “Detailed 
Analysis of Your Database Structure”  Here is the link if it 
is allowed on the Nug: 
"https://blog.4d.com/detailed-analysis-database-structure/“  
Something, clean, clear, and readable.


FYI: We are on 4D v16R5 at the moment.  Moving to v17 soon.

Any help is appreciated!

Thank you!!
Kirk

Re: Checking If Methods Are Preemptive Ready

[Dani Beaubien via 4D_Tech]

I am pretty sure that the METHOD GET ATTRIBUTES command will also return that 
information.

In my Code Analysis component, if you open the “Explorer” window there is the 
ability to filter the methods based on the preemptive capable attributes. Super 
useful and you can do it live.

Re: Fast way to highlight a listbox entity selection

[Keith Culotta via 4D_Tech]

Hi JPR,

Fuzziness is a good description, but things stand in sharper relief today.  I 
was more focused on the syntax than the mechanics and for no particular reason 
started out with collections.  Converting the app to an entity selection 
approach is turning out to be much easier than expected, and much easier than 
converting from an array based approach to a record selection approach would 
have been.

The collection listbox that was crashing was also in a subform.  I did not 
think that was important, but it may have contributed to the failure when 
highlighting records.  The subform was unnecessary, as was using collections 
for this purpose, and abandoning those two approaches has resolved the crashing 
and some performance issues.

The 40k example was a stress testing step.  Most lists should be very much 
smaller, and cueing the user with a visual highlight will be more practical.  
Thanks to the way 4D implemented the Highlight Set in the past, highlighting 
has been a very useful tool that seemed to have no cost.

Thanks,

Keith - CDI
