Traditional Caché Objectscript has the multi-dimensional array as its main form of complex data structure and the $order command as the main means of traversing said data structures. But newer versions of Caché ObjectScript also have data structures that are direct parallels of what languages such as JavaScript provide, in the form of %DynamicObject and %DynamicArray. These have an easy to use iterator feature via the %GetIterator method, and even a handy built-in literal syntax for constructing new objects.

Hello, I'm trying to install CSP Gateway on Ubuntu 18.04 (Apache) with the installer CSPGateway-2018.1.1.638.0-lnxubuntux64.tar.gz but it doesn't seem to work. I keep getting access-denied when I try to open CSP-pages or the CSP Management portal.

Does someone have an installation-manual or so ?

Hi community.

I'm trying to create a "setup" method to be called on a batch script but i'm getting the error <INVALID ARGUMENT> when I pass a string as an argument to this method.

The idea is to call the method with a folder as the parameter, for example:

##class(test.MyClass).MyMethod("D:\path\to\my\file.json")

My class (just for example)

Class test.MyClass

I need to dynamically create a class based on a parameter passed into a class method. Basically the method takes in a string that contains the name of the class I need to create a new instance of.

I need something along these lines.

ClassMethod someMethod(className As %String)
{
	set classObject = ##class(className).%New()

...
}

Trying to do this right results in a class not found error because it seems to be treating the variable as a literal string.

DICOM to HL7

We have a case where a vendor can send us more information in the DICOM message rather than in the HL7 result message. In theory it should be possible to take a DICOM and convert it to HL7, stupid question is has anyone done it before? Does anyone have any good examples of a DTL they did to show me how to setup the message structures and translation?

Thanks

I have created a fairly simple process for taking a HL7 message and sending it to an external provider via a HTTP Post and this is all working correctly. However for the request and response messages I am using e a simple structure containing only a message stream and when looking in Ensemble Message viewer none of this stream content is showing (it is all blank). Would I have to create a particular message type to make this show in message viewer and if so could someone provide some guidance around how to achieve this (outline of code included below)

Let's say I want to execute this cache script (saved as test.txt) from OS terminal:

zn "USER"
write 1
zn "%SYS"
write 2
halt

Executing the following command in a terminal:

csession cache < test.txt

Would yield this output:

$ csession cache < script.txt

Node: gitlab-test, Instance: CACHE

USER>

USER>
1
USER>

%SYS>
2
%SYS>
Job succeeded

Is there a better way to run these scripts?

Currently I have two problems:

Too often users finding themselves in need of a software solution do not consider “open source” vs. “proprietary” alternative. Most of them either have their go-to favorite developer or just google for reviews and ready-made answers. However, this alternative must be the starting point of their search, as the decision has the most consequences.

It is not an overstatement to say that open source is the future of technology, albeit, it has its own unique challenges. Here is what users, especially corporate users should consider choosing the software for their business needs.

Hi,

I am using a standard EnsLib.HL7.Operation.FileOperation to create files based on HL7 messages but I just realised that lines in the output file only contain CR (Character Return) but no LF (Line Feed). It is really important to have both as another system picking those files will fail otherwise...

Is there any way to configure this?

Thanks

How to convert SQL persistent classes to JSON output - I have tried 1 option but appears to be very lengthy process.

I have many other SQL storage's defined and have to expose them as well to JSON. Can anyone please suggest a better approach.

My column names usually match with my Json properties.

My User.TestClass is the class with GetJsonList() as my method to return /output JSON formatted data.

The Code tried and SQL storage structure are as follows -

Get Day of the Week from Date

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
    }
}

I'm trying to execute a nodejs process to perform some work on a string from Cache/Mumps over to nodejs, then return the result from nodejs as a string back to the code in Cache and I was looking at the `$ZF` logic - it will let me output the results to a file (i.e. temp.txt) but I dont see a way to just get the output set back to an M variable like (and I know this is not the correct syntax, but just for example)

S myOutput=$ZF(-100, "echo something") ;; wrong syntax but just for example

W myOutput ;; want to write out "something" but of course this doenst work

I"m doing a SQL insert in my BPL, one of the fields in my SQL table is an MSSQL TimeStamp. How do I get the date/time from my HL7 message and format it so that I can then insert it into my TimeStamp column in my SQL table? I've tried lots of different combinations.

I used CONVERT(DATETIME, substring(:request.GetValueAt("EVN:RecordedDateTime"),1,8)) to get just the date portion and it works, but I'd like the whole DateTime inserted into my TimeStamp field. This is an a BPL.

Thanks
