Read data from Excel

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

REST for Tasks on my Status Report

I enjoy the challenge of being in a contest. Currently I participate in InterSystems IRIS with REST API Programming Contest. My idea for this contest was to create an app to help me keep track of tasks for my Status Reports. I started with the template provided by Evgeny Shvarov. I created a persistent class for Tasks and a REST Dispatch class. I defined my URL map and I even figured out how to test my REST app using Postman.

I understand RecordMaps can be used to send delimited files through a production without custom coding. The data segments are delimited by tilde character followed by $Char(10) in Linux/Unix. When I test the same IO data in Windows, I have $Char(13) and $Char(10) instead of just $Char(10). I like to use just tilde character for record delimiter and ignore $Char(13) and $Char(10) between the tilde and the leading data of the next segment / record. Is this good idea or not if someone wants to generate classes will it override code?

Export Report to Excel

Hello, I created a Zen Report and I want to export to Excel. I read I can use $MODE=xlsx but my output in Excel is not correct. All 3 elements are condensed into one cell. Class AETMON.Report Extends %ZEN.Report.reportPage { /// Class name of application this report belongs to. Parameter APPLICATION; /// Specifies the default display mode used for this report if /// the URL parameter, $MODE, is not present.

Dashboard - Line Graph

Hello,

I want to create a dashboard with a line graph that shows system availability over time. I used this code to create a Dashboard:

            Set tItem = ##class(%DeepSee.UserLibrary.Link).%New()
                Set tItem.fullName = "Availability"
                Set tPage = "Availability.UI.CSVImport.zen"
                Set tItem.href = $system.CSP.GetPortalApp($namespace,tPage)_tPage
                Set tItem.title = "Availability"
                Set tSC = tItem.%Save()

Expand EnsPortal

Hello,

How should I go about it to add a page to the EnsPortal? I want to display a dashboard like page and I would like to be able to have it accessible from Management Portal. I hope there is a better way than typing the URL in address bar. Is the menu for Management Portal editable?

Thanks,

Oliver

Hello,

I try to open an existing log file and append to it. In Windows I use Open file:(NRW):1. I would expect it to append to the file, but each time I execute the code I get only the new entries, the prior file content is lost.

What is the proper syntax top open a file in "Append" mode?

I will deploy this code in Linux. Is there a different syntax to open a file in Linux versus Windows?

Thanks,

Oliver Wilms

Hello,

I have a DTL to transform X12 Document 278 Request to 278 Response HIPAA 5010 schema. The DTL is called from BPL. I defined a class method that receives source, target, and context objects. How can I create 2000F loops in the response when there were none in the source object?

Hello,

We have a BPL that returns in Response several %Strings, Dates. When we try to add Array of Objects property to the Response we verified just before the BPL terminates the response object has correct values in all properties including the array. We checked the Count(). It appears that even array of String works correctly but we prefer to pass objects rather than strings.

80 bytes wrapped X12 files

Hello, our X12 File Service won't process files we encountered X12 files where they inserted CR LF after 80 bytes repeatedly in the middle of segments. X12 Parser does not seem to like it. I see there is a Whitespace property in Adapter. I am not sure if it ignores white space in the middle of a segment. I also heard about TolerateNewLine setting but I believe this also does not tolerate New Lines in the middle of a segment. We will probably have to read the file, strip out any CR and LF, write to a new file that the X12 file service can process.

Hello,

We are in process of moving our first Production from development to test. We exported our project from Studio. On test server, we cannot Open the Production because it is not a valid production because nothing exists in Ens. Config.Production class. What are we missing? How do we add our Production in Ens.Config.Production?
