In the previous part of this series, we saw how to define a basic portlet. Now we will look into making this portlet reference a web page that will enhance our dashboard experience.

In this example, we will be embedding a Developer Community article along side a couple of widgets displaying information related to the number of views on the Developer Community articles. This example is not hosted on the Community Analytics server, but if it was we could see the view counts going up as we interacted with the page.

Why use this?

In a real case, perhaps you have an embedded page from an external web site showing the current Emergency Room wait times for Hospitals in your area. This portlet can be used along side widgets from your Emergency Room showing how many people are waiting, how many doctors are active, and how many people are being treated. As other Emergency Room wait times grow, you can possibly expect your volume to increase as well. This can help you make decisions on how to allocate resources.

Hi all,

is it possible to omit the typical XML header line

<?xml version="1.0" encoding="ISO-8859-1" ?>

when writing an the contents of a EnsLib.EDI.XML.Document using the above mentioned operation. I´ve already digged into the config value Format. It only states that:

C(e) : output an XML header line declaring character encoding e. If e is empty use the encoding defined by the Adapter. If e begins with ! force the output stream's encoding. Note that this will be applied automatically for File Operations configured with a non-UTF-8 Charset

hi,

i have two where-clauses:

a) ... WHERE company=1 and product=7

b) ... WHERE product=7 and company=1

with other words the position of the where fields are swapped.

now the question is:

bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???

in my point of view, there is a parser/optimizer who cares about this, so i don't have to care about.

Hi!

Here is the question in Russian Forum regarding roots extracting.

In Caché ObjectScript we use exponentiation operator (**) to raise an exponent to power. F.e. let's raise 3 to power of 3:

USER> write 3**3 

27

And we use the same operator to extract the root.

USER> write 27**(1/3) 

2.999999999999999963

And 2.999999999999999963 is not 3, obviously.

How to extract roots properly in Caché ObjectScript?

Filtering a Filter

What would be the easiest or best way to filter the options presented by a filter control?

For example, suppose that I create a query using HoleFoods that uses a named filter to filter the product categories according to some criteria. When I display the query on the dashboard, I would like to provide a filter control that will allow users to further constrain the product categories. However, a simple filter control will display all the product categories available in the cube many of which are irrelevant to the current query.

Thanks for your help!

I have a tablepane in my Zen page that is tied to a class query. When the page first loads, the table is empty. A button onclick event causes the tablepane query to execute and load query results into the table. I want an onchange event from a datalistbox to clear the tablepane so that it looks empty as it was when the page first loaded. I have had no luck fiddling with javascript in the datalistbox's onchange.

Hello community,

I'd like to briefly announce three new packages, available on the Open Exchange / through ZPM, that can really help accelerate modern full-stack application development on IRIS. I announced all of these in a Global Summit session last week, but you may have missed it - and I hear there's a full-stack application development contest coming up!

Generative AI for image creation

Currently, many digital artists use generative AI technology as a support to accelerate the delivery of their work. Nowadays it is possible to generate a corresponding image from a text sentence. There are several market solutions for this, including some available to be used through APIs. See some at this link: https://www.analyticsvidhya.com/blog/2023/08/ai-image-generators/.

I've been running my review collections on OpenExchange now for more than 3 years.
I explained the principle I apply in a past article.
These reviews are the first step of the quality check in OEX.

My personal Credo
My expectation of OEX (expressed in extreme) is to see it rather as
a collection of jewels, than just a flea market.

SQL query in Dropdown

Hi Guys,

I have two dropdowns where if I select a type from the first dropdown I would like to populate all subtypes in the second dropdown as below (I've set showquery =true to show you what's going on )

but for some reason I'm not getting the query filtering to the required where clause.

eg. by select Bearing from the first dropdown I should only get 6 records in subtype dropdown, but I'm getting all subtypes

Hi

I have two tables: one a local table using cache and the other is via an SQL gateway connection to an MSSQL Server via a 64bit ODBC driver (ODBC Driver 17 for SQL Server).

When I try to join them on a date field I don't get any matches, and I know that there are matches, e.g. running both views separately returns resuls for 30/11/2022.

The following statement returns rows for the first table r, but nothing for the table l

Hi developers!

As a follow-up to my previous post on the Node.js Native API, I created a quick poll because it may be interesting to see what technologies developers are using in their applications around the world with IRIS & Caché. I put a poll below, just check all boxes you have used or plan to use with InterSystems technology.

Thank you all for your cooperation!

Filter by time in Routing Rule

I have a colleague that is trying to eliminate any HL7 transactions that have admit date/time of midnight from going to an downstream system within a routing rule. I have tried several different iterations of code trying to figure this out just in the routing editor. Without having to write an object script function is this possible?

Hi all,

We're in the process of creating several courses for creating custom business components for productions. This includes custom business operations, BPL processes, and custom business services. Custom Business Operations and Custom Business Services are both aimed at software developers while BPL processes can be also be created by business analysts. What are some gotchas or best practices you've learned that you wish you knew when first building these components?

We'd love to include what you've learned into these courses so others can learn from them as well!
