#ObjectScript

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?

This is a series of programming challenges for beginners and experienced Caché programmers.

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 :

I'm extracting text from HTML (more on how - here), and after I extract text it has two problems:

• Lot's of $c(10) control characters
• Multiple whitespaces

Here's an example of the text extracted from HTML page:

I have a class. In class there is an index. This index is for quick search on name property.

Class User
{

.....

Property Name as %String;

Index NameInd On Name;

.....

}

This class is mapped to some global ^GL(userId) = "Name*other data....****"

And there is also index global ^GLNameIndex(Name, userId) = ""

When I add new User entry through class, f. i.

S user = ##class(User).%New()
S user.Name = "Some name"
​D user.%Save()

calling method %Save() adding new entry to index automatically.

Recently, we scheduled two tasks (1008 and 1009) within Task Manager. Task ID 1008 is set to run after Purge Tasks (%SYS-ID:3), and Task 1009 is set to run at 7:00:00 each day.

In attempt to provide as much detail as possible, each of the tasks are as follows:

• Task 1008

  WHILE (($p($h,",",2) < $ZTH("10:00 PM")) && ($P($g(^Task.1008(+$h,$j)),"^",1) = +$h)) { J ^ROUTINE, ^ROUTINE2 D SUB^ROUTINE3 H 5 }

Dear Developer Community!

My name is Maks.

Hoping someone can help.

I need to convert a timestamp from the following format (YYYYMMDDhhmmss e.g. 20160105125915) to UTC time in the same format.

I presume I need to convert it to the system format ( like $HOROLOG ) and then use something like ConvertTimeStampToHorolog or perhaps LocalWithZTIMEZONEtoUTC but not sure of the syntax.

Thanks,

Conor

Hi all.

I have been using a command pipe to open/run UNIX scripts for months without issue. We recently installed the 2016 Caché Upgrade and now I'm getting the following error when opening the pipe:

<PROTECT> *OPEN[Q](|CPIPE|)

I assume some security or permission setting is to blame, but I'm not sure exactly what. Here's the snippet of code...

s cpipename="|CPIPE|"
s filepath="/path/script"
​o cpipename:(filepath:"R"):10

Any feedback would be greatly appreciated!

Cache 2016.2.1

the system offers $LISTNEXT as a way of looping in $LISTs and the documentation says this is much more efficeint than writing

for i=1:1:$LISTLENGTH(myList) { set value = $LIST (myList,i) }

I want to walk backwards in the list,

is there a $LISTPREVIOUS or do I have to use the followng syntax to achie

 for i=1:-1:$LISTLENGTH(myList)

How do we need to set a flag with quit command and what is it share some example?

These Globals are usually cleared out as part of the startup/shutdown processes. If your server never reboots how would you clean these out?

Is it possible to dynamically adjust the RetryInterval andFailureTimeout settings in a BPL?

I've got a business process that calls a web service operation to get a session ID from an external system. There is a string property returned in the body of the response that indicate an exception occurred in the external system. I have code in the BPL that examines the property and sets the status property to an error status when that occurs.

Hi, folks!

I'm sending emails with %Net.MailMessage.

How can I add a new line for the email body?

The code is:

dim msg as %Net.MailMessage = ##class(%Net.MailMessage).%New()
set msg.Charset="UTF-8"
do msg.TextData.Write("Dear  "_Username)
do msg.TextData.Write("Line1")
do msg.TextData.Write("Line2")
And I'm getting in email:

Dear UserLine1Line2

How can I get:

Dear User

Line1

Line2

Has anybody defined their own Cache ObjectScript (COS) commands and symbols? Is it even possible? For a list of currently used commands and symbols please use the following link.
