InterSystems IRIS 2019.1 has been out for a while and I would like to cover some enhancements for handling JSON which might have gone unnoticed. Dealing with JSON as a serialization format is an important part of building modern applications, especially when you interact with REST endpoints.

Hi all, I have released the latest version of VSCode extension for ObjectScript already a month ago, and finally a time for the info about this new release.

So, what's new in the release:

What's new in this version

  • added export setting "objectscript.export.addCategory" if enabled uses the previous behaviour, adds category folder to export folder, disabled by default
  • added Server actions menu, by clicking on server info from status bar. Open Management portal, Class Reference and toggle connection.
  • Class Suggestion in ##class, Extends, As, CompileAfter, DependsOn, PropertyClass
  • $SYSTEM suggestion by Classes from %SYSTEM
  • Import and compile folder or file by context menu in File Explorer
  • Server Explorer, now possible to open any other namespace
  • Macros suggestion

For details how it works now, look further.

Please Help.

When I busy capturing the information into the database and when you press insert button then following error  pops up.

Local host:57772 says  A JavaScript exception was caught during execution of Hyper Event: Type Error: Cannot set property 'value' of  undefined .

This error is produced by cache technology. Your assistance in this regard is highly appreciated.

Request for getting Audit/Reporting info.
The ask is for a count of inbound messages by distinct identifier.

My challenge is getting the unique identifer out of the RawContent column in the EnsLib_HL7 table.

Wondering if a temp table can be created to store the value then do a join?

In the below example I am wanting to use the 999998 value in the PID.

Hello, community!

I've stumbled on some unexpected behavior, and decided to check with you if this is normal. Basically, I'm rebuilding indices and the result is not journaling (which leads to missing indices at shadow server).

The $ZV is "Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2015.2.1 (Build 705U) Mon Aug 31 2015 16:53:38 EDT"

I have an example class 

Class tmp.A As %Persistent;

Index IP1 On P1;

Property P1 As %String;

for example there is one object which have P1 = 1, so

It’s often useful to make changes inside the current transaction, that would not be rolled-back if transaction is rolled-back. For example to do some logging.

This can be achieved by using global that is mapped to temporary database -- IRISTEMP. All globals that start with ^IRIS.Temp* are mapped to IRISTEMP by default. Problem with such approach is that IRISTEMP is cleaned on InterSystems IRIS restart, so this log is lost.

What else you can do is -- suspend transaction temporarily, do the logging, and then resume the same transaction.

Hello,

 

I try to open an existing log file and append to it. In Windows I use Open file:(NRW):1. I would expect it to append to the file, but each time I execute the code I get only the new entries, the prior file content is lost.

 

What is the proper syntax top open a file in "Append" mode?

 

I will deploy this code in Linux. Is there a different syntax to open a file in Linux versus Windows?

 

Thanks,

 

Oliver Wilms

I have created a custom container that contains medication adherence data. I want to know the best-practice way of querying the data for to display in a custom Zen page in the Clinical Viewer for a given loaded patient.

 

Let's say the custom class is called Hospital.Data.MedicationAdherenceData. Let's say the streamlet class is Hospital.SDA3.Streamlet.MedicationAdherenceData

There are many projects which work on InterSystems products, and they are not always written only in ObjectScript. I think some of you working with different programming languages and already have some experience with other editors, and hope you already have a favourite online editor. 

My current choice is VSCode, whereas you may already know I have added an extension to support ObjectScript.

Hi Dev Community,

My team is currently working on a project where we need to post pdf documents to a 3rd party REST API.

The API specifies a field in the JSON request message to contain the 'physical content' of the file as an array of bytes, example of the JSON request as follows - data truncated for readability purposes:

Hello everyone,

Anyone can help me please. We use SOAP web service with public methods and have many instances of these classes, all work fine. We would like to create a new SOAP web service but for internal usage only, meaning not available to the public. The purpose of this is for communication between different servers internally.

We thought of having the methods to be Internal, WebMethod instead of just WebMethod.

Any suggestions?

Regards

Ben

Hi 

Quick question... Is it possible to save a class in another namespace. If you're saving a global you can just use an extended reference, but is it possible to achieve the same when saving a class object?  Obviously the class will be defined in the other namespaces too.

I want to do it from an Ensemble SOAP Service. I guess you could switch namespaces, but I was a bit worried about doing that from Ensemble process.

thanks

Hello,

Working on to learn very basic CUSTOM Business Service which sends to a EnsLib.File.PassthroughOperation.

But operation is not writing to File and erroring out (No Stream contained in StreamContainer Request")'.

How do convert the object to STREAM and wrap in the StreamContainer so the operation does not error and write to a file.

Thanks.

Hello,

When i click on the menu to  run the  Data import wizard  from MP, i receive following CSP error

<UNDEFINED>zOnPageHEAD+229^%cspapp.exp.utilsqleximwizardcontent.1 *schemaname : CSP Error

 

It is happening for all the namespaces. Looks like some permission issue.  Same issue with Data Export wizard. Help to resolve this will be appreciated.

I am using

Cache for Windows (x86-64) 2017.2.2 (Build 865_0_18763U)

Thanks,

Jimmy Christian.

This is embarrassing. I should know how to do this but I have forgotten.

I know the slowness of the 'Source' and 'Target' parameters in Message message viewer being slow to load is caused by the Bitmap indices of Ens.MessageHeader.

I know I need to run the 'bitmap index clean up' routine for Ens.MessageHeader to fixed the issue.

 What I forget is how to do this?
