Generate and Validate Captcha Code

Suppose you have developed your own web app with InterSystems technologies stack and now want to perform a captcha validation on the client side in order to determine whether or not the user is human and make it safer. There are some modern frameworks to address the captcha issue, however most part of them needs internet access to generate codes and sometimes are complex to implement. Take this as basic example considering that image recognition has gotten too good. That's why you nowadays you tend to see more pattern recognition captchas than mere reading ones. (I.e.

Hi All,

I have a line of mumps code that creates a folder on a network shared drive.

Example:

d ##class($Library.File).CreateDirectory("\\share\folder\newfolder")

If I run this line of code from a cache terminal window it works fine and creates the folder without problems.

However If I create a very simple business operation in a production in the same namespace that simply runs this one line of code then the code fails.

Hi Community!

Sometimes I meet a method which accepts 10+ parameters.

And often I need only the 8th parameter to pass. And I call the method something like:

do ##class(Some.Feature).Method(,,,,,,,"flag")

And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.

How do you avoid this situations?

If you meet such a code, how do you call it and sure that you didn't miss the number of ","?

What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?

I am trying to fetch the data from cache database. But i got the error like "CSP application closed the connection before sending a responce".

Below is the query.

SELECT
CallbackComment
FROM SQ.CBPhoneResult_View Where PhoneDateODBC = '2018-04-09'

I have investigated and found that "CallbackComment" contains the special character single quotes " ' " for one result and due to this i got this error.

In this field data is enter by customer. so we cannot restrict them like Do Not use single quotes.

InterSystems' iKnow technology allows you to identify the concepts in natural language texts and the relations that link them together. As that's still a fairly abstract definition, we produced this video to explain what that means in more detail. But when meeting with customers, what really counts is a compelling demonstration, on data that makes sense to them, so they understand the value in identifying these concepts over classic top-down approaches. That's why it's probably worth spending a few articles on some of the demo apps and tools we've built to work with iKnow.

In the first article in this series, we'll start with the Knowledge Portal, a simple query interface to explore the contents of your domain.

IRIS supports of Python and C++

I cannot find those folders under my IRIS install dev folder. Those were in my cache install dev folder.

Will InterSystems drop those support? If yes, why are there some discussion about Python/Iris in this forum?

Of course, I wish IS continue to support those.

Get variables list

Hello!

In Caché there is a way to print all current variables using write command without arguments:

USER>set Einstein = 1879
USER>set Mozart = 1756
USER>write
Einstein=1879
Mozart=1756

But is there a way to get a list of this variables? I am looking for something that would return value like $LB("Einstein", "Mozart") for this case.

Thanks!

Using Grafana directly from IRIS

There have been some very helpful articles in the community that show how to use Grafana with IRIS (or Cache/Ensemble) by using an intermediate database.

But I wanted to get at IRIS structures directly. In particular, i wanted to access the Cache History monitor data that is accessible by SQL as described here

https://community.intersystems.com/post/apm-using-cach%C3%A9-history-mon...

and didn't want anything between me and the data.

Hello everyone,

I'm trying to authenticate a user(Health Share clinician) from a Java Application.

I 'm already connected to Caché and able to run SQL commands.

My question is: How can I authenticate a user using only SQL? In fact, what I want is verify if the users exists in the base and if the given password is the same used in Health Share.

There is a column 'password' in Security.users table but I'm not able to see its content, even so, I don't know which hash function to use to compare with.

OpenAPI Suite - Part 1

Hi Community,

I would like to present my last package OpenAPI-Suite, this is a set of tools to generate ObjectScript code from an OpenAPI specification version 3.0. In short, these packages allow to:

  • Generate server-side class. It’s pretty similar to the generated code by ^%REST but the added value is the version 3.0 support.
  • Generate HTTP client classes.
  • Generate client production (business services, business operation, business process, Ens.Request, Ens.Response) classes.
  • A web interface to generate and download the code or generate and compile directly on the server.
  • Convert specification from version 1.x, 2.x to version 3.0.

Is there a straightforward workflow in VS Code for moving a class from one namespace to another on the same server? With Caché/IRIS Studio, it was a (sort of) simple export/change namespace in file menu/import operation. But in VS Code it's not obvious (to me, at least).

I can add multiple namespaces to a workspace, but when using isfs:// paths I see only a "Download" option and no "Upload" or "Import/Compile." When I'm navigating the local file tree, I see Import options, but no way to select the namespace into which I want to import.

A customer is using Caché online backups and needs to automatically purge the cbk files with a scheduled task.

This is a wheel has been reinvented uncountable times already and I know somebody out there has a well written, extremely robust version that has already stood the test of time.

Does anyone have a nice routine/class/task for purging old Caché backup files?

Hi everyone, how do you run multiple quires?

I have tried couple of different ways, but not working.

Set sql(2) = "UPDATE QUERY"

Set sqlStatement=##class(%SQL.Statement).%New()

Set sc1=sqlStatement.%Prepare(.sql)

If $$$ISOK(sc1) {

Set tResult = sqlStatement.%Execute()

}
