So I know it's been a while, and I hate to let my adoring fans down... just not enough to actually start writing again.  But the wait is over and I'm back!  Now bask in my beautiful ginger words!

For this series, I am going to look at some common problems we see in the WRC and discuss some common solutions.  Of course, even if you find a solution here, you are always welcome to call in and expression you gratitude, or just hear my voice!

This week's common problem: "My query returns no data."

How do i do the following:

Pass multiple values from one class to an excel report class using multiple tabs?

I want to request the data in the request class using a SQL statement changing values in the SQL statement, and then parse the values to the excel report to each sheet respectively.

How do I do it?

Dear colleagues,

a recent project came up with the question if it is possible to "restart Cache from inside", ie. using a COS-routine.

Thank you in advance and regdards

I thought I'd share some issues I had today with Zen development in a custom component. Say we have created a Zen composite component with a few javascript methods that modify its child components. In order to modify these components, we can use something like the following method:

In JavaScript methods on the client, this refers to the current component or page. The equivalent for expressions that are values of XML attributes is zenThis (see documentation).

Recently I started working with GitLab - GitHub self-hosted foss alternative. So far so good, liked the UI,  ease of administration, and available functionality (I was on Phabricator previously,  and still use it for repo mirroring).

GitLab has GitLab CI  (GitLab Continuous Integration) which looks promising (pluggable docker/vm/ds to run code) , but I wondered if someone uses it already and can share scripts for it?

Typically the thumbsup/thumbsdown icons are grayed out until you vote for one.  Then it is either red or green depending on which you selected.  I like this behavior.  However, on my own posts, the ones I cannot vote for, the indicators are both colored.  Since the visual queue has already been established that this indicates a selected vote, I think this should be changed.  Perhaps, since we cannot vote on our own posts, completely hide them.

Hi, Community!

We are fixing groups, tags and message types for the several last year's postings.

So that's why you are getting "strange" notifications now with no any new comment.

As a result, you'll get better tagging and for the DC articles and questions.

Anyway, you can turn off the "OnUpdate" notifications as it is described here.

I know this has been suggested before but I wanted to bring it up again.

It would be very nice if we could "accept" an answer to our questions which would result in the question showing "answered" in the index and possibly move the "accepted answer" to the top of the answer chain.

see: Stack Overflow or any other QA site

Hi Community!

In this release we turned off the digest mode for all the members (until it would be fixed) and fixed the Update notifications: now this settings can be found in the same place for all the members: Subscriptions/Content types tab.

Meet in this small release the new very valuable feature: marking answers as "true" answers.

If you are an author of the question now you can choose the right answer if there are more than one and mark it with the green checkbox. Like it is shown here:

If there are more than one answer, the "true" one will be shown topmost.

Hi, Community!

Anyone know where I can find a higher quality version of the favicon used in the Ensemble production interface?

Does anybody know good interesting and detailed articles or maybe bookes about the binding of SSL сertificates?

Thank you.

Is there a way to have a Data Lookup table be automatically updated via a script or cache code? We have a file that is being created by our EMR, and we need to import it into Ensemble to update it. Just trying to see if we can automate this process.

Thanks

I posted a question and someone replied with a comment.  
This comment  was marked as an answer, but the comment does not actually answer the question. 

How do I tell the system that the comment is not actually an answer and should not be marked as answered?  

Can the original post author decline an answer?  What is the  answer is incorrect?

Can the community vote on the best answer (like on other popular discussion boards)?  

Hi!

Today DC supports the notifications for the posts' updates. It means if someone changes the post text, title, group or tag you can be notified about that.

But this notifications just inform that there were updates, but do not show what exactly was changed in the post.

So through this, you can get the notifications for the posts from previous years without any reason what's happened.

I would suggest to turn off this types of notifications until we'll implement the details in notifications, what exactly was changed in the post and why did you get it. 

There are two tags with the same name "Web Services"

The same problem for tags: REST Services, Delegated and Monitoring.

All,

Totally new to Cache and Encryption.  Have a project requirement for SHA-512.  

Recently we have exercised this with a partner. It may be helpful for others as well.

The basic functionality is to connect to SAP through SAPJCo (Supporting SAPJCo 3.07+).

As a first step have a production with at least two items of the following type:

• EnsLib.JavaGateway.Service
• EnsLib.SAP.Operation

Configure the settings for the Java Gateway and the SAP Operation accordingly. And start the production.

Now the library sapjco3.jar needs to get imported to be used by further internal functionality.
Therefore start in a browser the webpage for simplified SAPJCo base installation

When working with a large query executed though an ODBC connection what is the best way to allow the paging of the results at the client side.  I have tried some methods using %VID and similar methods, but these really don't seem to work as the value returned is related to the ID of the data and not the position in the results set.  What would be ideal is if the value seen in the management portal when you check of "Row Number" was available to external queries through ODBC.  I have not seen a way to return this however.   This would be similar to SQL server Last n and Skip n capabilities.

How are we doing THIS year versus the same period LAST year? 
This is a common need in Business Intelligence. In fact, many design specifications for reports make use of a comparison between a selected period (year, quarter, etc) up to a certain date (for example November 15th, 2016) and a summary of the same information for the previous year (i.e. up to November 15th, 2015). 
This post shows how to implement this in DeepSee.

I just received three subscription digest emails that seem to have come from the past. For example, one included this fragment:

But when I follow the link from the email the article date is much older:

Did the DC software have a glitch?

Hi all,

I've a problem with EnsLib.FTP.OutboundAdapter

I've configured this adapter using a SFTP connection, it has been working the first time but now its raising the following error message:

ERROR <Ens>ErrFTPPutFailed: FTP: error al colocar archivo '1600000107279008930.pdf' (mensaje='Error in SFTP Put('C:\stream\QhFaDm4L1Jrgbg.stream','mypath/1600000107279008930.pdf') ERROR #7500: Error SSH '-2146430933': SSH Error [8010102B]: Unable to send FXP_OPEN* [8010102b] at SFTP.cpp:539,0',código=0)

Hi!

I want to optimize the cube and delete the measure. Is there any easy way to find pivots which use it?

Does anyone have any snippet regarding this?

Would be great to have "out of the box" dashboards which will show the dependencies of pivots vs measures and dimensions.

Hi All,

I am new to this technology and I have installed the trial version of cache 2016.1 with Normal security.

I was trying to develop the sample cinema application and mean while when I tried to view the csp webpage, it opens the browser and ask for login after logging in it shows Service Unavailable error instead of preview of webpage.

Could you guys suggest an answer to resolve this issue.

The 2017.1 FT keys expired on December 31st 2016. Can we have a new set?

There is no obvious way to provide feedback to the development community. In order to find the topic to find open discussions, I had to search for "feedback".

There should be links in standard places; without doing research these place probably include: menu, front page, footer.

This article is one of the series which introduces Eclipse to experienced Caché/ Ensemble/ HealthShare users. The goal is to open the perspective of a developer who was using Caché Studio for years and make Her/ Him see deeply into the Eclipse world – far beyond Atelier. In other words it is an Atelier (Eclipse IDE for InterSystems technology) beginner’s guide. This time the topic is: editing XML files using Atelier.

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):

I'm currently re-engineering an application from CSP pages directly accessing COS Methods, to an Angular/Material front end accessing a REST DAL.  Both the Angular front end and REST services are hosted from the same Caché instance and the same namespace, but the REST services have their own CSP application, with all calls being routed through a Dispatch class.
