The following code snippet is a REGEX that validates characters that are not in English, as well as English characters. The class method "test" takes an email address and validates it based on this additional criteria:
Sometimes, we need to copy part of the properties of an object into a different one. The simplest thing would be to do the following:
Set obj1.FirstName = obj2.FirstName
Set obj1.SecondName = obj2.SecondName
What happens if the object contains a large number of properties? or we just want to extract an important group of data, and complement the information in another object?
I want to share four functions with you. I hope that you can use it at some time.
DNI: the initials of the type of national identity document, is composed of different series of numbers and letters. That proves the identity and personal data of the holder, as well as the Spanish nationality. Example: 94494452X
NIE: The NIE or foreigner identity number is a code for foreigners in Spain.
Caché prints to printers in a manner somewhat different from other Windows applications. Caché sends the data directly to the GDI Printer, without the usual interface. This is because the GUI interface can only be shown on a system desktop session and not in web browser and terminal sessions. Some printer drivers have problems with this method of printing.
It is often necessary to run some external command such as a python program or a shell script from inside Caché/Ensemble. There are three ways of doing this:
Caché will not change the cryptographic settings in an existing TLS configuration when you upgrade. This means that unless you've updated them yourself, you're still using the values from the very first version you started using SSL in.
It was my answer to the question appeared in GoogleGroups. And when I answered there I figured out that it might worth to post an article and to add some light on how Unicode is stored in Caché.
If you have an app that uses some Caché client Windows components that are not included into CacheODBC distribution (e.g. CacheActiveX.dll), you need to proceed Caché client installation on end user's client computers and/or MS Terminal Servers. Being a part of Caché client's installation, Caché Cube is installed along with other components and is autostarted with every user's session. So, it becomes visible to every user.
To make it completely invisible, you can just move CACHE.lnk file from
If you are facing out the license expire warning message on your terminal ("*** Warning: This Cache license will expire in 3 days ***") and you do not want that message to be displayed, you can disable/enable that by rinning the following commands:
Twilio is a great tool for programmatically initiating and managing phone calls. In this example we'll go over basic account setup, create a Cache Class to manage our interaction with the Twilio API, and initiate a phone call from the Cache Terminal.
The full Class used in this example is available on GitHub as well.
I wanted to share a little tidbit which is in the Studio documentation (http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls?...) but many people who have been using the InterSystems Studio for a long time missed the addition of this *very* useful feature, and every time I mention this to an audience I see at least one face light up because of how excited they are to learn about it!
Within Studio, the Output pane (View -> Output) is actually misnamed. It is actually an Input/Output window which can be used to run Caché ObjectScript commands!
In this article I would like to tell you about macros in InterSystems Caché. A macro is a symbolic name that is replaced with a set of instructions during compilation. A macro can “unfold” in various instruction sets each time it is called, depending on the parameters passed to it and activated scenarios. This can be both static code and the result of ObjectScript execution. Let's take a look at how you can use them in your application.
Caché offers a number of methods for going through a collection and doing something with its elements. The easiest method uses a while-loop and lets you fulfill the task in an imperative manner. The developer needs to take care of the iterator, jumping to the next element and checking if the loop is within the collection.
Recently I was conducting a remote support session with a site. The desktop they were sharing with me was on a PC configured with German as the native language. Since my German is rather rusty, and virtually non-existent when it comes to computing terms, I was glad to be able to switch the Portal session into English.
This is done from the page that appears when you use the About link:
I'm looking for some field experiences, lessons learned, or actual deployed solutions to the problem of replicating non-CACHE.DAT data in a mirrored Cache environment.
Prompted by this post about accessing a global at its original location after you have changed a mapping, here's a tip about one specific dropdown in Portal that's sometimes useful.
If your application is raising <PROTECT> errors and you're finding it hard to work out why, here's a way to get additional information.
First, if auditing is not already enabled, turn it on:
Then use "Configure System Events" (highlighted above) and locate the event named %System/%Security/Protect. In the screenshot below I used the Filter field to do this (type "protect" - highlighted below - and press TAB):
It's almost time to get your customers upgraded to new versions - are you worried about showing off your SQL Performance after upgrades? If you want to upgrade without worrying, then I have just the program for you!!! Check out this video from Global Summit 2016 featuring yours truly explaining how to upgrade a system without worrying about pesky SQL queries showing on your waistline!
Prior to 2017.1, whenever I created a new namespace using Portal on Ensemble or HealthShare it was automatically configured to host productions. This used to irritate me, because sometimes I'm setting up a namespace (for example, to host our Deltanji tool) that doesn't need the extra Ensemble baggage.
