Hi, Community! 

Please find a new session recording from Global Summit 2017:

Atelier for Web Development

Hello, 

I would like to implement the Activity Monitor in a Sharepoint page. 
How is it possible to integrate only the Zen element?

Is it necessary to develop a CSP application in which this element exists?

Has anyone done this before and can I get a tip?

With kind regards
Armin

Sometimes you can face the situation when you did update the web app on Caché server but you cannot get the newest version of the app in a browser.

Here are couple recipes which help me to solve it. From simplest to more sophisticated and not obvious.

1. Refresh page in a browser

In Chrome it is Ctrl+R or 'Refresh' button. Obvious, but helpful.

2. Hard reset in a browser

If you are in Chrome, open Developer tools

and then right click on Refresh button.  Less obvious and very helpful sometimes.

3. Clear cache in CSP Gateway

If 1 and 2 don't work for you, try to flush the CSP Gateway cache.

Open Caché

Hi Community!

Angular, JSON, and REST – Oh My!

I have an application that as part of the registration process is using reCaptcha to provide a captcha. The issue is that service is served from Google and is unavailable in certain countries, namely China. I've been researching this some and believe it's possible to proxy the requests to the Google CDN to avoid the Chinese firewall ban on Google URLs, however I'm not quite sure how to do this in CSP. 

Does anyone have suggestions on how to solve this, either with a technical solution or an alternative service I can fall back to?
An example would be greatly appreciated.

Thanks

Hi

Please can someone send me an example of how to auto refresh a table pane. 

Thanks

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports.  We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down.  We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page.  I am new to Cache so any help would be greatly appreciated.

Also, is there an easier solution to this print all problem?

I've mentioned the QEWD project in this group before: it's a Node.js-based platform for web, Native and REST applications which tightly integrates with Cache.  It uses a somewhat different philosophy to the use of Node.js than the norm, and I've now published an article that explains this approach and the unique benefits that arise as a result.

It turns out that, integrated via QEWD, Cache is an ideal bed-fellow for Node.js.  QEWD makes the integration of Cache and Node.js exceptionally fast, simple and intuitive to use, but also extremely powerful.

Hi !

Can any one help me with this error? When the web site is run in localhost it is okay, but when run in server I'm getting this error. 

Hi world, i work actually on an intersystems project , my question is :

i've my Rest class that receive an HTTP request from a client side , i want to know how extract data from this http request , for example : date , id_client and measures taken by the client ( i need to extract  a weight value catched from a connected scale to my smart phone via bluetooth ) .

Thank you

a.k.a..  "The World of Widgets Returns!" or "Paternity leave damages Instructional Series momentum"

In our last lesson, we combined 2 separate classes to appear as the same property.  We now have the ability to Update our Widget catalog, but what if we want to Create a Widget?  Thankfully, we've already done 90% of what we need, just by implementing Edits

As we mentioned when creating the REST Services for PUT and POST, the only real difference between creating and updating a record is whether we are passing in an existing ID or creating a %New record.

In my previous posting about the new support in QEWD for JSON Web Token (JWT) support, I mentioned that it was a key step in enabling Micro-Service support in QEWD.  In this post I'll give some background to how they work and the thinking behind them.

If you haven't heard about Micro-Services and/or want to learn more, there's lots of information available if you do a Google Search.  Here's a good starting point:

Hi,

I have been working on a csp page and trying to export it to excel using the standard activex object. I would like to know if it is possible to export the table on the page with formatting to excel? Thank you in advance for any insight.

Thank you,

Subba.

TablePane1 is populated when a %ZEN.Component.button on a form is clicked from a JavaScript onclick method.

<button caption="Search" onclick="zenPage.onSubmit();"

TablePane1 also has a JavaScript onselectrow method zenPage.onSelectRow() that gets the currently selected RowID.

onselectrow="zenPage.onSelectRow()"

This JavaScript method gets the RowID and feeds it into ClassMethod GetAuditLogs(ByRef pRowId) [ ZenMethod ] to get the audit events for that record.

ClientMethod onSelectRow() [ Language = javascript ]{
var table=zenPage.getComponentById('table1');	var dataRow=table.getRowData(

Greetings!

I'm new to Zen reports and I'm wondering if what I'm trying to do is possible.  I have a classmethod  that accepts three parameters to generate an xml file from a global.    I've set up my Report Definition to call the ClassMethod that generates the .xml file; however, I'm trying to figure out how to pass the parameters to that ClassMethod from the Report Definition.  The example in the documentation shows parameter passing using SQL (which I'm not using), so I'm curious if this will work.  

Hi Guys,

We need to print html reports, in the server side, to a specific printer that is installed on the Cache Server , and using the Internet explorer that is installed on the Cache Server to do that .

Hello All,

While extracting the huge amount of data in the cache through the Zen page, file extraction timing is greater than session time out. How to increase the session timing in Zen/CSP gateway or If any other solution would be appreciated.  Please advise.

I have a Caché server with external apache.

It has a hostname, i.e.: http://myserver.com

There is an index page, which is available over http://myserver.com/index.html (/ is a Caché CSP app)

How can I make index.html available from http://myserver.com?

Here's the relevant parts of my apache config:

<Directory />
    CSP On
    DirectoryIndex index.html
    Options FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>
<Location />
    DirectoryIndex index.html
    Options FollowSymLinks 
    AllowOverride All
    CSP On
    SetHandler csp-handler-sa
</Location>

If you read my previous post that introduced QEWD Micro-Services, you're hopefully eager to learn how to use them.  So in this post I'll explain what you need to know in order to get started.

If you look in the QEWD repository, you'll find the folder: 

  https://github.com/robtweed/qewd/blob/master/example/jwt

In my earlier post on JSON Web Tokens (JWTs) and QEWD I used this example application to explain how to use JWTs. This example application also demonstrates how to set up a simple Micro-Service, in this case a service that handles user authentication.

I've written previous IDC articles about QEWD and how it provides a very high-performance, yet simple-to-use, way of integrating Node.js with Cache 

Hi All,

We have a application currently running on Zen framework, now business wants to use Angular JS as their front-end technology for any future release but they don't want to upgrade the existing the modules which are already there in Zen (as of now).

Hi,

I am trying to create a new dashboard using zen page for different namespaces. Could someone give me a sample code on how I can start designing the page for different namespaces in a single zen page/zen application.

This discussion is open to anyone who use or know about WebTerminal project. It is a result of a long story of the project development, testing and maintaining.

While WebTerminal greatly improves user experience by enhancing standard terminal with additional features, there are numerous issues (#77, #92, #81, #87 and others) showing that it performs not as expected in some cases, and does not support some very basic things (like $ZA/$ZB variables). The reason is in fact that WebTerminal project tries to reimplement Caché TERM behavior over Caché

I have a tablePane that always displays with the bottom row selected. The SQL is executed when the submit/search button is clicked.  See attached.

Does anyone know how to enable row selection but prevent the bottom row being selected after the button onClick event?

In our last lesson, we implemented a linkage to our WidgetAccessory class, and debugged some errors we encountered along the way.  We now have our data being returned by REST, but what if we want to update or add new data to our application?  

So far we have only used HTTP GET commands with our REST Services, we now have to implement PUT (which roughly corresponds to an Update) and a POST (which roughly corresponds to a Create.  Author's note: there is a lot of writing online about why this statement isn't entirely correct, I'm not going to go into the detail here).  However, before we start,

or "Things are going to break"

We left our application over the weekend, secure in the knowledge that it was returning data from our primary persistent class, User.Widget.  However, Widgets Direct are the premier supplier of both Widgets AND Widget Accessories, so we should really start working on adding these Accessories to our application. 

We should do some housekeeping first though. Our Page Controlller code is currently sitting in the widgetmaster.js file.

Hi!

I have a question:

I create a Operation REST API , when I call to my client trough this REST API, my cliente returns list of object in JSON, like that:

[
    {
    "Center" : "aaaaaaaaaa",
    "Nif" : "00000000T",
    "NumberCenter" : "00000000",
    "Name" : "ppppp",
    },
    {
    "Center" : "aaaaaaaaaa",
    "Nif" : "00000000T",
    "NumberCenter" : "00000000",
    "Name" : "ppppp",
    },
    {
    "Center" : "aaaaaaaaaa",
    "Nif" : "00000000T",
    "NumberCenter" : "00000000",
    "Name" : "ppppp",
    }
]

About the Ontodia library

First of all, I think we should provide some background information about Ontodia and Caché DBMS. Let’s start with a less known product, Ontodia. Ontodia is the result of a joint project of the ISST lab of the ITMO University and VISmart, a software development company specializing in the semantic web domain. The Ontodia service was created as a web application for visualizing linked data and ontologies. We created this service because we couldn’t find simple, accessible and efficient tools for convenient visualization of linked data.

A typical use case for Ontodiа

In our last lesson, we added some formatting and validation to our Edit Widget form.  So, now we are ready to add the ability to add new Widgets to our application.  However, the great Widget Wars have come to an abrupt end, as Widget Direct has purchased its biggest competitor, WorldWideWidgets.  In order to maintain some continuity, we need to display their catalog on our new application.

So, we have good news and bad news.

In our last lesson, we added a form to Edit our existing Widgets, and save them back to the server.  However, our Form was not well structured and our Save button had no intelligence, and was not fully visible.  So today, we will apply some Material components and Angular style to make the form more useful

Let's open EditWidget.csp, and make some changes. First, we want to change the component from an md-card to an md-dialog.
