In this post I show strategies for backing up Caché using External Backup with examples of integrating with snapshot based solutions.

Hi all,

I'm pleased to announce this personal project to convert a number to text, in spanish, english and catalan.

the aim of this function is to convert numbers into text. It allows a maximum number of 15 digits.

This code snippet determines the day of the week associated with a date. The class method "test" takes a date as a string in "mm/dd/yyyy" format, and returns an integer corresponding to a day of the week:

Class cartertiernan.getDayfromDate Extends %RegisteredObject
{
    classmethod test(date) as %Integer {
        //Set date = $ZDATE(date) //  Looks like: mm/dd/yyyy
     
        Set monthList = $LISTBUILD(0,3,3,6,1,4,6,2,5,0,3,5) // (Jan,Feb,Mar,Apr,...)
        Set centuryList = $LISTBUILD(6,4,2,0) // first two digits divisiable by 4, then subsequent centuries. EX (2000, 2100, 2200, 2300)
        Set dayList = $LISTBUILD("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday") // Index goes from 0-6
         
        Set day = $PIECE(date,"/",2) // get the day 
        Set monthVal = $LIST(monthList,($PIECE( date,"/",1 ))) // get the month value
        Set first2DigsYear = $PIECE( date,"/",3 ) \ 100 // get the last 2 digits of the year
        Set last2DigsYear = $PIECE( date,"/",3 ) # 100 // get the first 2 digits of the year
         
        // Used for DEBUG perpouses
        /*write !,"day: ",day
        write !,"Month: ",monthVal
        write !,"last2: ",last2DigsYear
        write !,"first2: ",first2DigsYear
        write !,"cen Val: ",$LIST(centuryList,(first2DigsYear # 4) + 1),!!*/
         
        // Look here for formula explination (its the "Basic method for mental calculation")
        // http://en.wikipedia.org/wiki/Determination_of_the_day_of_the_week
        Set dayOfWeekVal = ( day + monthVal + last2DigsYear + (last2DigsYear\4) + $LIST(centuryList,(first2DigsYear # 4) + 1 ) ) # 7
     
        Quit dayOfWeekVal
    }
}

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:

Hi everyone!

I want to share four functions with you. I hope that you can use it at some time.

Problem:

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 in

Hi!

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:

Here is a snippet that I learned yesterday

You can define an index on a collection property but when I tried to use it, I failed. I was using

Hello everyone,

From now till the 25th of december each day 2 programming problems to sharpen your programming skills.

This small function is of great need sometimes. My solution is straightforward:

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 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

Introduction

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!
