write #

Hi

Is there any way to control what control sequence is sent to a device when a "write #" is executed?

I have an application that establishes a banner at the top of the terminal window and when we do a "write #" the banner disappears. I need to be able to recreate the banner line as part of the screen clear.

Thanks

Jenna

I have an OAuth 2.0 development environment where Caché is serving all three roles as the Authorization Server, Client and Resource Server based on a great 3-part series on OAuth 2.0 by @Daniel Kutac. I have a simple password grant type where an x-www-form-urlencoded body (as described in this post) is sent as a POST to the token endpoint at https://localhost:57773/oauth2/token and a response body with a HTTP Response 200 header is returned. The response body looks something like this.

Hi,

I am trying to use the LogicialToDate method in the %Library.FilemanDate class. In the class documentation it talks about the parameter STRICTDATA (see below). I would like to set the STRICTDATA to a 1 but I am not sure how to do that when using this method because the method does not reference this as a parameter to be passed into it. (see below).

How do I set the parameter?

Thanks

parameter STRICTDATA = 0;

Just wondering if anyone knows if there is a way to get daily emails or alerts about changes to a cache database. I know that all of that information is contained within the journal files, just wondering if there is a way to bundle it up each day and send it off for auditing, etc.

Any solution where a plain-text/readable format of changes to the cache database could be sent or stored for review would solve the issue.

Thanks!

Hello,

I am struggling to print out the actual property values of the Security.System class.

https://cedocs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls

I was hoping to be able to print the Authentication Enabled properties of a system from the command line using the Get or GetProperties class method. Currently, however, I am only able to get a return 1 or Invalid Oref error.

ODBC connection error

Hello,

There is a problem connecting clients through ODBC.

"ERROR [08S01] [Cache ODBC][State : 08S01][Native Code 459]
Connection via cconnect failed:
TCP connect() failed - exception satisfied select().
Reason: (10061, 0x274d) No connection could be made because the target machine actively refused it."

Error sometimes occurs. In cconsole.log there are only messages about high CPU usage.

ODBC and Cache version Cache for Windows (x86-64) 2013.1.4 (Build 801).

Any suggestions?

For Cache client install automation, where are the remote server settings stored on a Windows 10 PC?

Are they stored in the registry? I found the Cache registry key, but it only lists the remote server address and not the ports.

Are they stored in an INI file? If so, I haven't found it yet.

I can push the client install via the very helpful CEDocs URL (https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GCI_windows_silentinst)

A SOLID Design in Cache Object

In this session, we will discussing SOLID Principle of Programming and will implement in a example.
I have used Cache Object Programming Language for examples.
We will go step by step to understand the requirement, then what common mistakes we use to do while designing, understanding each principles and then complete design with its implementation via Cache Objects.

Anti CSRF Methods

IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.

See the following link from OWASP for the definition of a CSRF attack:

Cogs Library

Cogs Library

Over the next few months I will be releasing a number of open source libraries and tools to the Caché community.

Most of the code has evolved from previous production grade solutions over the years and I am collating it together under a single overarching library package that I am calling Cogs.

CodeGolf: FizzBuzz

Let's have a round of CodeGolf!

As usual the goal is to write the shortest solution for a specified problem.

Today we have one of the classics: FizzBuzz.

Write a program that prints the numbers from 1 to 100.

But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.

For numbers which are multiples of both three and five print “FizzBuzz”

Hello community,

I need to know if there is any method which can me say specified imported files or namespaces in Cache.

To better specification of my problem, I've got two installer manifests. Firts one did some resource changing and import some files and classes, second one must be started after the first one, because it's only his update, which creates some nemaspaces. So i need to check if the first manifest ran succesful and I can start the second one.

Hello,

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:

(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()

License Server summary view of active key.

Distributed license use:

Current License Units Used = 1

Maximum License Units Used = 1

License Units Authorized = 200

Local license use:

Current Connections = 1 Maximum Connections = 1
