How to put a character limit on a textarea?

I want to limit the length of the value of a textarea in Zen. In HTML the textarea element has a 'maxlength' attribute, but the Zen component doesn't have an equivalent property. Is there any way to add a maximum length in Zen short of creating my own custom component?

Zstrip to clean string

I'm extracting text from HTML (more on how - here), and after I extract text it has two problems:

  • Lot's of $c(10) control characters
  • Multiple whitespaces

Here's an example of the text extracted from HTML page:

set text = " "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" Word1"_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_"

Yet Another Way to Duplicate Quotes in String

This small function is of great need sometimes. My solution is straightforward:

dupquote(str) ; duplicate quotes in str    quit $replace(str,$char(34),$char(34,34))

I'm just curious whether other solutions exist. Is there some "standard" and/or quicker approach which I've just overlooked?

Get class property position in storage $lb

I have a classname and a property name. I want to know, when I get object value directly from a global, which property corresponds to which position in the $lb structure.

Here's what I got so far:

Machine Learning with Spark and Caché

Apache Spark has rapidly become one of the most exciting technologies for big data analytics and machine learning.Spark is a general data processing engine created for use in clustered computing environments.Its heart is the Resilient Distributed Dataset (RDD) which represents a distributed, fault tolerant, collection of data that can be operated on in parallel across the nodes of a cluster.Spark is implemented using a combination of Java and Scala and so comes as a library that can run on any JVM.

Ensemble/Healthshare server sizing on Amazon AWS EC2 servers

I am designing the software architecture for an Ensemble/Healthshare production to be deployed on Amazon AWS EC2 servers (2 mirrored m4.large - 4 vCPUs / 16 GiB RAM running RedHat Linux  3.10.0-327.el7.x86_64 and Healthshare for RHEL 64-bit 2016.2.1). It's a rather CPU-intensive production involving massive XSLT 2.0 transformations (massive both in terms of size and volume). I was wondering if anyone has experience configuring Ensemble productions on EC2 servers. My question or concern has to do with the following statement in the Ensemble documentation:

Content-Type in REST

Greetings to all!!!How to get the value of the Content-Type field from the object of the class %Stream.Object obtained with: 

stream=% request.GetMimeData (FormDataName, 1)

I tried:

write stream.GetAttribute("Content-Type")write %request.Get("Content-Type")

but always returns a void, although it should be "image/jpeg", "application/pdf" or something like that.
In JS:

    var formData = new FormData();
    formData.append('file', element[0].files[0]);
    console.log(element[0].files[0].type);

The console of browser displays "image / jpeg", "application / pdf",  etc.

Define PoolSize as system default value

Hi all,

For special definition of the company, we need to define a PoolSize according to the environment that the "Ensemble" is working.

So the first try as been add the parameter into "System Default Setting"

However, this parameter is not available in "Setting default values" in Setting tab.

I've opened the code of my production and I've noted that this parameter is a attribute of the XML element of this item

Creation of a High Availability Group

A lot of tools in InterSystems products are designed to help facilitate high availability solutions (Mirroring and ECP come to mind readily). Since a lot of concerns about these technologies are in a similar thread regarding High Availability, I believe it might be worthwhile to create a High Availability Group within the Developer's Community.
What thoughts do people have on the addition of such a group?

DICOM TCP-Services and DICOM implementation details in Ensemble

Hi everyone,

before contacting WRC i thought to ask dev com about some questions related to Ensemble DICOM related implementation. These are more practical things and I hope to have someone around with experience in the field. We´ve created a DICOM Worklist application and are now in the process of roll-out.

1) One of our customers came up with a question to bundle modalities of certain locations to use a single Ensemble Service (EnsLib.DICOM.TCPService).
