Currently, when we want to write data to a file that will be viewed in Excel, we parse the data in tab deliminated format to the file and name it with .xls at the end. That is sent to end users via email. They get a warning that the data is not formatted properly (it's not really an Excel file after all) but it does display somewhat correctly as the tabs are understood (this does not work if we deliminated with commas however).

Question:

How do I get a list of files residing in a certain folder/directory, according to some wildcard/filter.

For example all '*.txt' files in 'C:\Temp'.

Answer:

In CACHE –

You can use the %Library.File's FileSet class query.

Here's some sample code using it (also attached):

Hi guys,

I'm curious about the development processes of those of you using Angular.

The starting point is that, somewhere, there lives an Angular project full of (mostly) typescript files. Eventually, those files need to be built, and the resulting built files served up to a browser.

The Ensemble Scheduler is used for automatically turning on and off business hosts at certain dates and times. You could use it if, for example, you wanted to only run a business host from 9am to 5pm every day. Conversely, if you want do to trigger an event to occurr at a specific time, for example, a job running at 1am to batch up and send off all the previous day's transactions in one file, we recommend other methods such as the Task Manager.

A “Dummy” SOAP Web Service

When dealing with SOAP in Caché, it is sometimes necessary to debug errors by directly accessing (and sometimes editing) the XML which is sent, i.e. the SOAP request and subsequent SOAP response. If you’re debugging a Caché web service, it is often useful to use a tool such as SoapUI (https://www.soapui.org/) to manually create and control the SOAP request, so that the effect of adjustments can easily be seen on the Caché web service.

Guys,

Can you please guide me to create a RESTful API in our cache with JSON response.

Hi,

Can anyone point me to an example of a DTL & Class method that can pull a base64 encoded PDF out of a MDMT02 message?

This is really asking for two things;

- how to make a DTL that extracts a specific subfield of an HL7 2.3 message into a message of its own,

and

- how to transform an base64 encoded document into its original binary form for writing to a file.

I'd also love to see an example of an HL7 2.n MDM^T02 ==> HL73.ITK2 non-coded CDA

ObjectScript has at least three ways of handling errors (status codes, exceptions, SQLCODE, etc.). Most of the system code uses statuses but exceptions are easier to handle for a number of reasons. Working with legacy code you spend some time translating between the different techniques. I use these snippets a lot for reference. Hopefully they're useful to others as well.

Hi Developers!

Often when we develop some library, tool, package, whatever on InterSystems ObjectScript we have a question, how we deploy this package on the target machine?

Also, we often expect that some other libraries already installed, so our package depends on them, and often on some particular version of it.

When you code on javascript, python, etc the role of packages deployment with dependency management takes package manager.

So, I'm pleased to announce that InterSystems ObjectScript Package Manager available!

Hi All,

We are doing capacity planning. I want to track the number of rows and size of each table (or at least the top ~10). Any ideas?

Thanks

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status.

{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.
