Hi

I'm using a class which extends %XML.Adaptor adaptor and I want to create an XML file with multiple namespaces, like the following:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
</soap>

However, I don't see how to do this with the code I have. So far, I have

Hi folks!

I'm curious if it is possible to change the class method to another class?

I call a method of a system class  to generate another class. But there is a bug/feature in a library class, so I need to tweak a bit the generated method, e.g. add additional parameter and change the line to "if" the parameter.

I hope to do this programmatically after class generation and change the code in a way I like.

What are the options?

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are: 

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

Hi Dev Community,

I have a persistent Document class that has a FileName string property and another Question class that has an optional one-to-many relationship with Document.

I'm trying to add a SqlComputed property to the Question class (docFileName) where docFileName = Document.FileName if there is a related Document or an empty string if there isn't one. 

I'd prefer the property to be SqlComputed so that if Question.Document changes, Question.docFileName will automatically update.

Hi all, 

I'm trying to output a XML file, mapped from a ORU_R01 2.3 HL7 message, with a file name based of fields in the source HL7 message in the following format, 

source.{PIDgrpgrp(1).PIDgrp.PID:PatientIDInternalID(1).ID}_"-"_
source.{PIDgrpgrp(1).PIDgrp.PV1grp.PV1:VisitNumber.ID}_"-"_
source.{PIDgrpgrp(1).ORCgrp(1).OBR:ObservationDateTime.timeofanevent}

To give something like RXR0000000-000000123-20211125105415.xml as the output filename,

Hi, Community!

Open Exchange (OEX) is getting more and more popular and more and more developers consider publishing their apps in the public package manager registry.

This is really great!

So the topic of thoughtful naming convention is getting more important and even critical.  Let's discuss?

Hi all

I'm new to ObjectScript and I've been experimenting the correlate method of %XML.Reader to convert an XML file I've loaded into its corresponding class. But, I have found that I am not getting all the child items of an element in a List contained within the converted class, only the last item.

The XML file content is as follows:

I programmed some server command by my own. That server commands worked fine for a long time.

Suddonly I received 

Studio Action "Attempted Edit" not supported on 127.0.0.1:57772[CTAE01]

by using one of my server commands.

There is an explanation:

Error running command vscode-objectscript.serverCommands.contextOther: Running the contributed command: 'vscode-objectscript.serverCommands.contextOther' failed.. This is likely caused by the extension that contributes vscode-objectscript.serverCommands.contextOther.

InterSystems technologies are renowned for their high performing databases, which support the systems and operations of many organisations. However a key ingredient to this success is the quality and maintainability of their code. 

The quality of code can impact everything from speed and ease of fixing bugs and making enhancements, to the overall performance of your organization and your ability to get ahead in the marketplace. 

By ensuring your code is maintainable, you can reduce approximately 75% of the systems life cycle costs*. This is why, at George James Software, the solutions we build are always straightforward and written in high quality code - because we know that this solid foundation can positively impact the rest of your organization. 

With a maintainable system you're able to reduce your overall maintenance as any issues that occur are significantly faster to identify and fix. This means you're free to allocate that time and budget to enhancements, enabling you to get the most value out of your applications and ultimately better support your organization. 

Keep an eye out for our next few posts about what a maintainable system looks like and the tools that can help you keep your code maintainable, in order to help you to reduce those maintenance costs.

Caché ObjectScript Quick Reference

In the Caché Foundations course, students are learning about Caché Development and ObjectScript syntax at the same time. To help students complete the exercises, we provide an ObjectScript Quick Reference (aka "the Cheat Sheet").

It is not a reference for all of ObjectScript! It is a list of the ObjectScript commands and functions that students use during the course, along with common syntax for objects, collections, etc. It also contains some useful macros.

Hello,

I don't know if the title is accurate enough. I have a legacy code that I need to optimize. It's a routine written in objectscript. It accepts 4 parameters and runs 6 nested FOR...$ORDER reading a big global.

The thing is when I run the routine the first time it takes around 60 seconds to run. If I run it again it takes 5 seconds. If I wait around 6 to 10 minutes to run it again, it takes 60 seconds again, but if I run it every 1, 2, 3... minutes it still takes only 5 seconds to run.

Hey everyone.

I was wondering if anyone had come across a way of reformatting ObjectScript within VSCode.

I have the various Intersystems Extensions installed (InterSystems Language Pack,  InterSystems ObjectScript,  InterSystems ObjectScript Extension Pack,  InterSystems Server Manager) but a formatter does not seem to be something included within this variety of extensions.

I am receiving the following error in my buisness operation:

ERROR <Ens>ErrException: <UNDEFINED>zGo2+181^mb.MbMainOperation.1 *tSC -- - registered as '-' number - @' set pResponse = ##class(mb.MbMessageResponse).%New()'

From what I understand, the problem occurs in the generated int file mb.MbMainOperation.1 in the method zGo2, with the offset of 181 lines, and the variable in question is a local variable tSC.

However, the line where the error occurs does not refer to tSC in any way

If I open a terminal and type the following commands, sc is an error:

set validator = "sc = ##class(%Library.Numeric).IsValid(""BLAH"")"
set @validator
write sc

At the end, when I write sc I get:

However, if I call the following class method using the arguments "%Library.Numeric" and "BLAH", sc is undefined
