Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

Hello Caché Guru,

I'm new to Cache system. I'm trying to do something like saving meta data in Relational DB:

I could use "management portal" -> System Explorer->SQL to view individual table's catalog details or print out the column definition. However I need to gather those information for several hundreds of tables in the DB. Is there a way to do it using command line in kind of batching mode?

Any hint and tip is very much appreciated!

Thanks in advance!

One for Luca, perhaps?

Interesting article here:

https://www.redhat.com/en/blog/containers-aren%E2%80%99t-just-applicati…

Would this be a fit for Cache / IRIS containerisation?

Not sure I fully "get" what's being proposed in the article, mind you.

The challenge for today consists of capsules that bounce through a maze of spinning discs.
The capsule can fall through a hole of each disc if they hit the disc at position 0,  each disc has a fixed amount of positions that rotate every second.
The distance between the release and the first disc is one second, as is the distance between each consecutive disc as well.

Hi everyone,

I started working on Ensemble this year so maybe I am not implementing the right way. I'm trying to connect a Welch Allyn monitor to TrakCare. The workflow is the following:

- User scans patient number with the monitor.

I am using Cache FTP classes to download from a FTP site files, that include zip files.

I can retrieve the whole file into a stream, but it contains a lot garbage.

Sample:

Hello,

I'm looking for a way to programmatic ally add the parameter 'VALIDIFNULL' to classes that extent %SerialObject.

This to hopefully resolve the validation errors I'm getting  on webservice request messages, where certain properties are not required, but lower down the tree some properties are.

I have too many classes to do this manually and with the next SOAP wizard run I probably loose the added parameter.

Some help would be very much appreciated.

Regards, Michel

I searched fror "documenting classes" from the search button with no filtering. it naturally came back with 559 responses, but to me, the responses (and therefore the search)  came without context.

for instance,  one of the texts came back with:

In first you should define ODBC DSN in your operation system, to your Oracle DB.  Then you can look at this page in the documentation and class %SQLGatewayConnection Vote up! Vote down! Rating: 0 .

Hi, folks!

Consider I need to perform some logic which should fire because values of object properties has been changed.

Is there ANY reason for using class callbacks %OnBeforeSave or %OnAfterSave instead of Trigger?

I have a couple of new namespaaces/databases that are read-only.  I don't remember changing them to read-only, and although my username has %all (I installed the system), I am unable to change the "Always mount as read-only" property.

What am I missing?

Thanks,

Laura

The challenge today is about some basic cryptography : you will have to generate data for a one-time pad (OTP) (see https://en.wikipedia.org/wiki/One-time_pad for more info).

You need to generate keys by taking the MD5 of a pre-arranged salt (your puzzle input), and an increasing integer index starting with 0.

Hi communauty

i work on the Oauth2 authentification patry in my application , i read a lot of documentation , but i don't know exactly what does it mean by Claims values and the method "SetClaimValue", what does it do really?

can anyone explain for me.

Thank's.

I’ve hit the wall. I’m a one person shop who wants to start developing Cache on a mac using Eclipse/Atelier, after using Studio for the last 5 years. I’ve installed the 1.1 beta plugin, watched 6 or 7 videos from the September conference, tried several times to work through the cheat sheets, only to have connection issues or compilation issues, so at this point, I’m feeling very frustrated. The videos were interesting, but generally didn’t work as tutorials for fundamental programming operations, for me.

the useful content is in the replies
showing the use of $SYSTEM.OBJ.ValidateIndices()

When a class containing a method generator is compiled, the code that implements the method at runtime is written according to the instructions in the method definition. 

Hello guys,
I'm having a problem on a sign-up screen, what happens is that this screen is not reloaded after clicking save, and that's where the problem arises, on that screen it is possible to upload images, but as everything is loaded withsubmit, the record would have to be updated so I had all the information, which does not happen.
With this I'm trying to find a way to get the information from the file loaded in the "file" component to get the data in "% request.MimeData".
The only way I've found it so far has been to reload the whole page, but that's all I do not want to do.

A third party developer has asked for access to the documentation of my classes so he can understand my tables/classes better.

• How do I give access the the documentation of my classes (single namespace)  and secondary, do I need to give  him access to %system. (and others)
• Is it possible to block the likes of ensemble, Iknow, deepSee etc. I don't use those, and I don't want him to waste time (and my money) exploring areas that simply not necessary
• what privilege roles do I need to give him  whilst still maintaing security.

Today, you have to find a path through a maze. To know if a coordinate is a wall or an open space, you will have to do a calculation like this :

x*x + 3*x + 2*x*y + y + y*y
Add the office designer's favorite number (your puzzle input).
Find the binary representation of that sum; count the number of bits that are 1.
  - If the number of bits that are 1 is even, it's an open space.

As many of you, our partners, are more widely using modern UI frameworks to create client front-end, you may have encountered a question, "So how do I secure my data when I just finished developing all new fancy browser based client experience?"

The answer is easy. Use a standard, proven OAuth2 and OpenID!

"OK, but how can I do it? I have never done it before."

No problem, just have a look here, if your client is Angular (not AngularJS) based, there is a demo project available for you to review and get inspired!

Hi community

i'm working on the validation user method , i found this following  code in the  \HSIE\%SYS\Classes\%OAuth2\Server\Validate.cls  

ClassMethod ValidateUser(username As %String, password As %String, scope As %ArrayOfDataTypes, properties As %OAuth2.Server.Properties, Output sc As %Status) As %Boolean
{
    // Check if user is defined.
    // We use local Cache user list as the shipped default.

Once upon a time ...  No it's not a fairy tale.
In the beginning of Caché (and before) you had your partition to run your code. Part of that partition was a space with all your local variables nicely sorted by %,A,..Z,a,...z

And whatever values or information you had to store locally was there and visible and available to any piece of code running  in your

I am trying to make Caché perform certain actions depending on whether a particular property of the object was changed using triggers.

For example, say I have this class:

Class Dummy.Class Extends %Persistent {

Property Name As %String;
Property Visible As %Boolean;

Trigger OnUpdate [ Event = UPDATE/DELETE, Time = BEFORE ] {
    if ({Published*O} = 0) && ({Published*N} = 1) {
        do .CertainAction({ID})
    }
}

ClassMethod %OnBeforeSave(insert As %Boolean) As %Status [ Private, ServerOnly = 1 ] {
    // .

Today, you need to make a compiler for the language assembunny.
Luckily, this language has only 4 instructions :

cpy x y copies x (either an integer or the value of a register) into register y.
inc x increases the value of register x by one.
dec x decreases the value of register x by one.

Does anyone know where to find a cache.node that works with Cache version 2016.1.1.108.0? I am currently getting  this:

Error: Unable to load shared library C:\InterSystems\TryCache\bin\cache.node''

I am using Windows 7 Pro + SP1.

Thanks!

I would like to remove all the active locks and roll back all the on-going transactions.

Is there any COS command I could use?

By the way, any command I could see the current on-going locks and transactions?

Thanks.
