Hi -

I'm wondering if anyone has coded up a means to create an extension for a %Persistent class from a base class to a sub-class without making a ton of assumptions about the Global structure. I'm trying to create a new "extension" record that would have the same ID as the Base Class

Class BaseRecord Extends %Persistent

and

Class SubRecord Extends BaseRecord

where I would have an instance of a "BaseRecord" and I want to turn it into a "SubRecord" instance and have all of the existing references to the BaseRecord survive.

The following post outlines an architectural design of intermediate complexity for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings. This post introduces two new databases: the first to store the globals needed for synchronization, the second to store fact tables and indices.

Hi Everyone!

As you know Advent of Code 2018 is in full swing! Till the 25th of December 2018 each day 2 programming problems to sharpen your programming skills!

And now we're ready to present great prizes for Members of InterSystems Global Masters Advocate Hub!

Example: I have a list of tags that I have to find, and a string with these and other tags separated by commas.
How to find the desired tags in the string optimally?

Hi Community!

On behalf of Developer Community and Global Masters team, I wish you a Happy New Year 2019!

2018 was another great year for InterSystems Developer Community - thanks to you!

Here are a few highlights:

Added new System Default Setting for Production (not Host) setting.

However, Production setting is still the same. I have tried restarting Production and instance, to no avail.

How do I specify System Default Setting correctly?

Hey Developers!

Advent of Code 2018 is over! Thanks for participating in our small but productive COS marathon!

And now we're pleased to introduce the winners and distribute all the prizes!

Big applause goes to these winners:

I am trying to explore some new possibilities outside of the normal day to day HL7 interfacing we do. I have only done 1 other Web Service interface but it was using a SOAP proxy wizard. Now I am tasked with trying to make a call to an external API

Hi Community!

The following code walks a DOM using %XML.Node. It also prevents %XML.Writer to change whitespace. Run the code using the class method "test":

Class objectscript.walkDOM Extends %Persistent
{
    ClassMethod dfs(node As %XML.Node)
    {
        s entrynode=node.NodeId
        do {
        //element nodes with one whitespacetyped child are the ones we want to change
        if (node.NodeType=$$$xmlELEMENTNODE){
            s snode=node.NodeId     
            if (node.MoveToFirstChild())            
                {
                    i ('node.MoveToNextSibling()){
                        i (node.NodeType=$$$xmlWHITESPACENODE){
                            s node.NodeType=$$$xmlTEXTNODE
                            s node.NodeId=snode
                        }
                    }
            }
            s node.NodeId=snode     
        }   
        if (node.HasChildNodes()){
            d node.MoveToFirstChild()
            d ..dfs(node)
        }
        } while (node.NodeType'="" && node.MoveToNextSibling())
        s node.NodeId=entrynode
         
    }
     
    ClassMethod test()
    {
      set xml = "abcdefg<![CDATA[   ]]>"
     
      s reader=##class(%XML.Reader).%New()
      do reader.OpenString(xml)  
      set writer = ##class(%XML.Writer).%New()
      //do some magic
      d ..dfs(reader.Document)
       
      w !,"with indent=1:",!
      set writer.Indent = 1
      do writer.OutputToString()
      do writer.Document(reader.Document)
      w writer.GetXMLString()
      set writer.Indent = 0
      w !,"with indent=0:",!
      do writer.OutputToString()
      do writer.Document(reader.Document)
      w writer.GetXMLString()
    }
}

Hi Community!

Thank you for being with InterSystems Developer Community yet another year! We appreciate it very much!

We want to know how helpful DC for you today and how could we make it better.

Could you please go through this short 5 min survey which will let us know what do you think about DC and what could be improved.

We wish you a Merry Christmas and a Happy New Year!

Sincerely,

Your InterSystems Developer Community Team

The goal of this article is to give users of InterSystems products background on source control in general, and how it can be used with Atelier, an Eclipse plugin. Specifically, I'll be discussing what to do when all of your developers share a single dev instance of an InterSystems product where they can edit and compile code.

I am trying to use Entity Framework with Visual Studio 2017. After following the Intersystems documentation ("Using the Caché Entity Framework Provider") I still cannot see the data source in Server Explorer. Any ideas why?

how do you change a date format to dd-MMM-YYYY in cache
