Hello everyone,

I have a doubt, its possible to use interface like C# using COS?

Remember, interface is different from Abstract Class, because a abstract class can implement code in the method, so I don't want this, I want only define the methods from Class, not allowing implement code.

Image Download from URL


I'm currently struggeling with a HTTP request to a URL, which contains an jpeg image file.

Testing the request with a browser or Postman results in the image being shown normally.

Using a %Net.HttpRequest with different configurations has resulted in a corrupted file.

My code works for some URLs from other servers perfectly fine, but with some it produces corrupted file contents which do not represent a jpeg.

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!

Hi All,

Hopefully someone can help me with this case. I need to encrypt a text(querystring) with an AES265 encryption. An other vendor is decrypting this information. I have a working class in C#. I've tried to build the same in Objectscript for the encrypt part but there's a missing link somewhere. What's the difference between the C# and Objectscript implementation?

Objectscript code (until now):

Is there a way to add specific table permissions to a security role programmatically? I'm working on scripting some of the initial setup work when we sell certain add-ons to our software, and I see how I can assign resources to a role and give it a description, but I don't see how I tell it that this role gives the user, for example, SELECT privileges only on the invoices table, or SELECT, INSERT, UPDATE, and DELETE.

Hi all.

I have a process/operation within Ensemble that grabs a PDF from a webservice, and then saves it to an external location. All is well, except I am noticing that a lot of .Stream files are being stored on the Cache Server.

Does anyone know what causes these to be stored and what would trigger their removal? Would I be right to assume these would be removed if I ran Ens.Util.Tasks.PurgeMessageBank and the creation dates fell within the purge range?

Edit: I answered my own question on if the purge would clear them out. The answer is yes.

Hello ALL!

I am having trouble fining a way to derive (a list, an array, a file doesnt matter yet how it returns) ALL of the targets of a routing rule.

For example lets say I have:

  • a router of class: EnsLib.MsgRouter.RoutingEngine
  • Business Rule: HappyRRN
  • 1 rule set having 5 rules that each send to 1 DTL and 1 Operation (5 targets total)

My intent is to use some utlities we have created to disable all of the target operations of this router if the router errors out.

To do that I need the list of target operations.

Recently viewed a demo on the new Dynamic Objects in InterSystems (we are still running 2016.1); together with the upcoming IRIS data platform I started thinking about possibilities of building dynamic databases. That is, I can imagine some projects were it might be really nice to store dynamic objects and then run sql queries on them without ever defining the fields of the dynamic objects (i.e. not at storage, but only if you run your sql query).

I need to do a DELETE and then do some INSERT transactions on a linked table and don't want the DELETE and need to be able to ROLLBACK the DELETE if any of the INSERT transactions fail.
I have tried Object Script transaction processing (TSTART, TCOMMIT and TROLLBACK) and the SQL transaction processing (START TRANSACTION, COMMIT and ROLLBACK), but neither work.
Could I be doing something wrong in the way I am implementing these, or do does transaction processing simply not work for linked table?

Thanks for any advices, in advance.

Hi everyone,

I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.

I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.

I've encountered a peculiar behavior of $ListNext in Intersystems Cache, where I'm not sure whether I'm doing something wrong, or is it an intended behaviour.

First I am creating a ListOfDT from a string delimited with underscores:

Set tempList = $ListFromString(String, "_")
