Hi Caché-Developers!

My Caché Version: 2014.1 and the CSP-Gateway Version ( + Apache) also. I can't upgrade now. 

I want create a Web-Socket for my Chat  like in that Tutorial:

https://community.intersystems.com/post/tutorial-websockets

And there's my problem. When I set SharedConnection like:

set ..SharedConnection = 1

I get on init connection with the server that message:

First i think everything is okay but here i also didn't get the Messages on init from Server-Side:

When I now send a message to the WebSocket, I got following error:

Without SharedConnection = 1, everything works fine for

Hey Developers!

Want to beat the COVID-19 pandemic with InterSystems and MIT? Please take part in the MIT COVID19 Challenge!

It's a 48-hour virtual hackathon with the goal to develop solutions that address the most pressing technical, social, and financial issues caused by the COVID-19 outbreak.

And it's your chance to build a solution on InterSystems IRIS for the COVID-19 crisis! 

I know that collection is instance of %AbstractList.

But what about $listbuild? Does it possible to detect that given variable is instance of $lb?

Hi developers!

When @Evgeny Shvarov announced the first InterSystems IRIS Programming Contest, I started looking for new ideas. 

I put together a few ideas, and that's what isc-utils is about.

• Conversions
  • Temperature
  • Length

• Exchange Rate
• Weather

Temperature Scale Conversion

IRISAPP>write ##class(diashenrique.Utils.Temperature).CelsiusToFahrenheit(28)
82.4

IRISAPP>write ##class(diashenrique.Utils.Temperature).CelsiusToKelvin(28)
301.15

IRISAPP>write ##class(diashenrique.Utils.Temperature).FahrenheitToCelsius(82.4)
28

IRISAPP>write ##class(diashenrique.Utils.Temperature).

Hi Developers!

Create Database, Namespace, REST Applications using Portal Management is an easy task. You just need a few clicks or maybe more clicks than you expect.

But, what if you traded all those clicks for a simple command-line ?!

IRISAPP>do ##class(diashenrique.Utils.GenerateDB).CreateNew

You just need to answer a few questions: 

Do you want to create a new Database/Namespace? (Y/N) : 

Choose your Namespace name : 
Choose the Dataset location <Path Default is mgr directory> :
Make this an Interoperability namespace?

Hi Community!

The registration phase for InterSystems Online Programming Contest ends today and we will start the voting week!

Now we have 20 applications - so you have a set of applications to choose from!

How to vote?

This is easy: you will have one vote, and your vote goes either in Experts nomination or in Community nomination.

Hello,

We are developing a BP where we would need to call at the same time to get appointments in two external systems. So then, we would need two threads, one for primary care appointments, and other for specialist appointments . We need to paralelize both calls because of both of them require some time and we would need to shorten it as much as possible.

Hello,

I got the idea for this application, because for my work we have a process that currently uses legacy Vista code called MailMan to transfer files using email. I thought I could create a process in HealthConnect (IRIS Interoperability) to replace the need for having the legacy code. I have seen File Passthrough and TCP Passthrough Operations that can transfer a stream (file content) into a file or through TCP connection. I did not find Email Passthrough Operation, so I decided to create it. It receives request with a stream that has the content of the file.

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

Class eduardlebedyuk.changePasswords Extends %RegisteredObject
{
ClassMethod test()
{
set ns = $namespace
zn "%SYS"
set NewPass = "NewPassString"
set rs=##Class(%ResultSet).%New("Security.Users:List")
set st = rs.Execute()
while rs.Next() { set st=$SYSTEM.Security.ChangePassword(rs.Get("Name"),NewPass)}
zn ns
}
}

DISCLAIMER: I am not an InterSystems engineer or a professional ObjectScript developer.

I just want to share my opinion about some things I am really miss in ObjectScript.

I really appreciate everyone who support my project (Declarative ObjectScript) in contest

but the post is not about "why you should support me" on contest.

I faced with ObjectScript in the university while was working on my diploma (in 2013).

Very good mentor @Evgeny Shvarov helped me to get started with ObjectScript development.

Hey Developers,

New "Coding Talk" video was specially recorded by @Maks.Atygaevfor the IRIS Programming Contest: 

⏯ Declarative ObjectScript Promo

Here's what I'm trying to accomplish

I have a directory of CCDAs and files with basic demographic info.

I'd like to generate an outbound Provide and Register request by building the SOAP envelope (using the demographics data) and adding the CCDA as the document.

Which Operations / Components can I utilize for this?

Is there is a good starting point in the documentation I can use?

If anyone knows which specific Operations/Components I should use please let me know.

Thanks

Starting in March 2020, Microsoft plans to release a series of security updates that will cause Windows Active Directory (AD) servers to reject unencrypted simple binds. For more details on the changes to Active Directory, see Microsoft’s Security Advisory ADV190023.

Instances of all InterSystems products using LDAP with Windows AD servers for user login can be impacted if they are not already properly configured to use TLS/SSL. The impact is not limited to instances running on Windows versions.

Hello,

We're considering adopting the ZPM solution as a way to manage many of our customer updates. However in order to do so we need to know a few things.

• Is ZPM client compatible with Caché 2017.x versions?
• Can we configure a self-hosted registry that doesn't require a GitHub repository link?
• Could the ZPM client zip and upload the whole package (all classes, routines, includes) instead of downloading it from a Github link?
• Can we declare a module that specifies classes themselves instead of their package counterpart? e.g. My.Class.CLS instead of My.PKG.

Hello,

We have been reasearching how could we parse a string with a JSON structure like the following:

{"code":200,"type":"Consulta","message":"Operacion correcta","result":[{"id":38802130,"paciente":null,"prestacion":{"codigo":"1.

Hello,

While working on my Iris contest application FileMailer, I got an error today trying to send email with code that used to work. I added debugging entries and I can see it happens in %Net.SMTP class "Send" method. I am not using any credentials or SSL. I see it opens |TCP|25 device. It issues a series of commands to SMTP server (I was testing with smtp.va.gov and port 25). "init" command gets 220 response.  It runs "Login" method. Response is 250. The next command is "MAIL FROM" and I see 250 in the response with sender ok. The next command is "RCPT TO".

Hi Community,

The new video from Global Summit 2019 is already on InterSystems Developers YouTube:

⏯ Understanding System Performance Metrics

Introduction

The common requirement in many applications is logging of data changes in a database - which data has changed, who changed them and when (audit logging). There are many articles about this question and there are different approaches on how to do that in Caché.

I'm sharing a mechanism that can help you implement your framework to track and record data changes. This mechanism creates a trigger through an "objectgenarator" method once your persistent class inherits from the "Audit Abstract Class" (Sample.AuditBase). Since your persistent class inherits Sample.

I am trying to create a simple example of allowing binary (tiff) files to be selected and uploaded asynchronously to an IRIS for Health back-end.   I have managed to write the HTML and Javascript which works great with regular text / ascii files, but fails with binary files.

Hi, participants of the InterSystems IRIS Online Programming Contest!

This is an announcement for the current and all the future participants of online contests.

To win the contest you need to gather the maximum votes of InterSystems Developer Community members.

Below are the few ideas of how to achieve that.

These Competition Terms (the "Terms") apply to competitions and contests sponsored by InterSystems and its affiliates including coding contests relating to InterSystems products and technologies (each a "Contest").

I hope you already know one of my projects Cache Blocks Explorer. I've recently renamed it to Blocks Explorer.

For the recent contest, I've added a new feature, the ability to generate a static picture of any Cache or IRIS database. Like below. Where unique globals have a unique color. This is how looks like inside 9.5GB database. Where 1 pixel represents one block. By link on image you will get even bigger image, with more detalization.

In Episode 6 of Data Points, certification manager Jamie Kantorjoins the podcast to tell us all about the InterSystems Certification program, what exams are currently being offered (and what ones are in development), and why it matters for developers and enterprises. Check it out!

Hello,

We are developing a method to take two messages which have a list of data types. It is being defined as:

Class Mensajes.Response.HistoriaClinica.ConsultaCitasResponse Extends Ens.Response [ ProcedureBlock ]
{

Property informacion As EsquemasDatos.HistoriaClinica.Informacion;

Property datos As list Of EsquemasDatos.HistoriaClinica.ConsultaCitas;

Property error As EsquemasDatos.HistoriaClinica.Error;

}

Inside datos we have:

Class EsquemasDatos.HistoriaClinica.ConsultaCitas Extends (%Persistent, %XML.

Hello,

We are developing a Transformation and we are wondering: how could we debug and show a XML message which is being an output from a transformation, without storing it into request/response/callrequest/callresponse? We mean, how could we show a context variable in the production?

For example, let's have a transformation which stores an appointment in a variable called: context.especializadasConFormatoPrimarias

How could we show in the Production?

I just tried to log into our QA server and connect to Terminal (v 2013.1). 

I can type in my username but when I attempt to type my password, no characters are typed. When I press ENTER the password is invalid. 

I can connect to the management portal and the studio development environment without any problems.  Also, I do not have this problem when connecting to the terminal in our production environment (2010). 

Does anyone know what can cause this type of problem? 

Thanks. 

Hello,

We have a tranformation where we would like to convert a date from the following format:

"'dd/mm/yyyy' 'hh:mm'" (double quotes are just visual to indicate this is a string)

to date and time separated:

date: dd/mm/yyyy

time: hh:mm

We have already splitted the datetime into date and hour as follows:

  set fechaHora = source.result.GetAt(indice).

Sorry about my newbie question.

How do you decide the size to give to journal1 and journal2?

PS: I am still in version 2016

Thank you
