Sometimes, we need to copy part of the properties of an object into a different one.
The simplest thing would be to do the following:

Set obj1.FirstName = obj2.FirstName

Set obj1.SecondName = obj2.SecondName

What happens if the object contains a large number of properties? or we just want to extract an important group of data, and complement the information in another object?

Having the following classes:

Hi,

I use cache 5.0 and access cache through OpenVMS.

The disk-space under a particular namespace has grown up in size due to cache.dat. How to recreate cache.dat to bring up more space back on disk?

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

Hi all!

In this article I would like to review those VS Code extensions which I use myself to work with InterSystems and which make my work much more convenient. I am sure this article will be useful for those who are just starting their journey to learn InterSystems technologies. However, I also hope that this article could be useful for experienced developers with many years of experience and open up new possibilities for them when using VS Code for development.

Hi Developers!

Often I find questions on how to install IRIS, connect to IRIS from IDE, setup the environment, compile, debug, maintain the repository.

Here below possibly the shortest way to set up all the environment and start development with ObjectScript on InterSystems IRIS.

Prerequisites

Make sure you have Git, Docker, and VSCode installed

Install Docker and ObjectScript extensions into VSCode

Sign in or Create an account on Github

Here we go!

Hi!

I am not system admin. But it used to be very simple to install CSP Gateway on an apache system on Linux with Apache installed. I used to run the CSP Gateway installation program and after it was done, all I had to do was fine tune some configurations on CSP Gateway portal on http://<ip>/csp/bin/Systems/Module.cxw and I was up and running.

In the previous parts (1, 2) we talked about globals as trees. In this article, we will look at them as sparse arrays.

A sparse array - is a type of array where most values assume an identical value.

In practice, you will often see sparse arrays so huge that there is no point in occupying memory with identical elements. Therefore, it makes sense to organize sparse arrays in such a way that memory is not wasted on storing duplicate values.

In some programming languages, sparse arrays are part of the language - for example, in J, MATLAB. In other languages, there are special libraries that let you use them. For C++, those would be Eigen and the like.

Globals are good candidates for implementing sparse arrays for the following reasons:

Hi,

I have created a Business Service which uses the EnsLib.File.InboundAdapter. This service will call a business service which will create an acknowledgement file in a directory specified in the operation after loading the parsed file into some temporary tables.

In order to create the acknowledgement file, I need the original file name. In the OnProcessInput of the service, it receives a stream of file data, and I can't find a way to get hold of the file name.

Any advice will be appreciated, thank you.

Good afternoon -

I'm in the process of learning to make COS calls to REST-based web services and while I am having success, I'm struggling on how to parse out the results (I admit I'm very green at this):

Here's the code retrieving the JSON response:

Hi,

I am trying to generate a custom error-code using the following code

Class ISG.CommonBilling.Service.Test1 Extends EnsLib.HL7.Operation.TCPOperation
{
    ClassMethod khalid() As %Status
    {
        Set tSC=$$$ERROR("10001","I am here")
        write $$$GETERRORCODE(tSC)_$char(13,10)
        write $SYSTEM.Status.GetErrorText(tSC)
    }
}

And here is the output:

csession can be called with a variety of arguments:

• tag+offset^routine
• tag^routine([parameter-list])
• ##CLASS(package.class).method([parameter-list])

Hi,

Hi,

I have a requirement to replace $ZF("%ZSET_DIR","/hold/rsm") to its equivalent Cache Class. The $ZF("%ZSET_DIR") sets the Current folder equivalent to "cd" command in Unix.

Can anyone help on this, please

Thanks & Regards,
