What's the use case?

Are you sure about:

Property PatientId As %Stream.FileCharacter;
Property PatientName As %Stream.FileCharacter;

Both of these fields are less than 3 641 144 characters in size, so

Property PatientId As %VarString;
Property PatientName As %VarString;

Would probably work.

You can add ToStream() method to your class to provide serialization, if you need to (Or just add JSON or XML adaptors to generate XML or JSON (de)serializations automatically).

What do you mean not getting called?

Is the child process created (check with $zchild/$test)?

Does it start work (set some global in the beginning)?

FOR CE ONLY.

I recommend creating non-production namespace with one database and calling

set sc = ##class(%EnsembleMgr).EnableNamespace(namespace, 1)

You mean these categories?

Fell free to use them as extensively as you want. There's absolutely no effect on performance.

It's not a file property. Docx is just a zip archive, inside it is docProps/app.xml file. Here's how it looks like:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Properties>
    <TotalTime>4</TotalTime>
    <Pages>8</Pages>
    <Words>1882</Words>
    <Characters>10731</Characters>
    <Application>Microsoft Office Word</Application>
    <Lines>89</Lines>
    <Paragraphs>25</Paragraphs>
    <CharactersWithSpaces>12588</CharactersWithSpaces>
</Properties>

Explorer reads the app.xml file and gets information from it.

You can do the same I suppose, here's an article on that.

In your case you don't want to unpack the whole docx, check this unzip implementation for ObjectScript.

Fastest (and in non-prod environments easiest) way to save every global would be:

1. Dismount the database
2. Copy CACHE.dat
3. Mount the database

Use system default settings.

You need to check access to table.

Try

write $SYSTEM.SQL.CheckPriv($username,"1,<TABLE>","a")

Replace <Table> with your table.

Check Purge method of Ens.MessageHeader class for example. Here's how it determines cast-off date:

set %tDoNotDeleteDate = $$$timeUTCHtoUTC($s($ztimezone'<0:($H-pDaysToKeep+1)_","_($ztimezone*60),1:($H-pDaysToKeep)_","_($ztimezone*60+86400)))

So 24 hours.

How do I search?

Tried:

https://github.com/search?q=language%3Aobjectscript&type=Code

but it yielded zero results.

Great news!

Coloring works, but still APEX, VB, TeX.

Check this article on iterating dynamic object.

Instead of just displaying the fields you can use %Dictionary package to generate corresponding class.

After that use new %JSON.Adaptor class (or old   %ZEN.Auxiliary.jsonProvider class) to parse JSON into objects.
