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.

I need to open a Windows explorer window by pressing button on a Zen page.

Is this possible.?  I

performed a search but I did not find anything.

The command I used in the terminal was  D $zf(-2,"START C:\WINDOWS\SYSTEM32").

I am not sure how to use this in a Zen application.

Any help will be greatly  appreciated.

Hello all,

I have a Recordset object  which contains data from a table "XYZ". 

Currently i use this object to extract data using  %Get(COL1,COL2...) in a loop and than pass it to a function which inserts the data into another dynamically created  Table "ABC"  for each record. This takes a lot of time when 100's of records.

Is there a way i can directly copy a RecordSet to a dynamic table without looping through..?

Something like copy Recordset (COL1,COL2..)--> "ABC"

In our table, we have a column cities,  which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String =  "CA"

Our filter should run this query to show all cities of state ca

Hi All,

I have two tables LB_TestSet and LB_Transfer

LB_Transfer has a list if TestSet row IDs, so i am doing the following join

FROM SQLUser.LB_TestSet 
WHERE LBTS_CollectedDate BETWEEN '2019-01-01' AND  '2019-05-10'


Without the date filter the query returns data, but if i add the date filter no data is returned

I also tried using %INTERNAL, %EXTERNAL TO_DATE('2009-01-01','YYYY-MM-DD')

Need some technique to solve an issue about zen page table.

- "xyz" table exists in all my namespaces.

I have a simple Zen page  in "USER 1" namespace. It has a tablepane which pulls data from "xyz" table.

OnLoad of the page i want the  zenpage to pull the data from "USER 2" namespace with same "xyz" table name.


Zenpage has to be in  "USER 1" namespace

I'm using ZEN report to generate a PDF file out a table.

Although, I need to display data from two tables splitted into two different namespaces.

So, I created a process that fetches all the data I need and then calls the PDF class and generates the stream out of it.


My question is, once I've got my list of objects. How can I transform it into a ResultSet, in order to display in the report ?

Thanks for your answer.

Hello Cache Developers:  I was curious if anyone has ever created a TWAIN interface to their Cache Application?   I am new to TWAIN and hence the reason for this question.  From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application.   I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table.    Any input, sample code, or suggestions is apprec

Looking for work

Hi every body

I hope it's the right place & I'm not offending any body.

I'm a veteran Mumps/Cache/Ensemble programmer .  I think my only draw back is my age, although my brain is still young & bubbly.

I'm looking a long time for work without success.

I gathered a lot of knowledge & experience during those long years , developed many projects & i'm ready to do any work only to feel useful.

I'll add my resume, I hope & wish that this post will bring some change as I'm desperate to get some work.
