I faced with the issue when WebSocket connection just fails without any errors if I send data with size 384 bytes and more (In binary mode the same). As I know by standard WebSockets frame does not have such limitation. Is there any way how to decrease it? This limitation too small, it is too difficult to fit this size and needs to send data much more often than I expected. Tested with Caché 2016.2, 2017.2 and IRIS 2018.1.

Does anyone have any experience with getting, unfortunately, an older version of Cache to authenticate via SMTP to send email? I have verified that the settings are set up properly on the mailbox as I have successfully sent an email from a LAMP server, which comes from the same IP address.

If you have any thoughts, I would greatly appreciate it.

This is the error I receive

ERROR #6034: SMTP server connection failed during MAIL FROM command: <READ>zSend+105^%Net.SMTP.1.

when I run the following.

or "Didn't you say you would cover Persistent Objects in Part 5, Chris?"

Yes, that was the plan.  This is a pretty important topic, so it get's its own Article

Up until now, we've display widget JSON that has been created by a basic loop.  Clearly this isn't of much value.  Now we have our stack connected together, and we can see that the data is flowing to the Welcome page, it's time to complete the stack and start feeding our service from "real" data.

I cannot connect to Cache from node.js  

I have installed in Windows 10 the following: CACHE 2016, node.js v 4.4.7 and  express .

-  where can I get cache.node? The link in the Intersystmes documentation  http://globalsdb.org/downloads/  doesn't work. I found cache0100.node and cache0120.node  in my Cache instance's  \bin directory. But I am not sure if I can use them or not.

 - how to install cache.node ? Where do I place it exactly? 

Can anyone recommend any tutorial or code example with installation instructions?

Thank you!

I have inherited a web-based database application and I'm having a hard time understanding the sequence of events when CSP pages are opened.  I have very limited web development experience.

Can anyone recommend a good resource for explaining this?  I have already gone through the Cache Cinema tutorial and the Cache CSP documentation.

In this article I would like to present the RESTForms project - generic REST API backend for modern web applications.

The idea behind the project is simple -after I wrote several REST APIs I realized that generally, REST API consists of two parts:

• Work with persistent classes
• Custom business logic

And, while you'll have to write your own custom business logic, RESTForms provides all things related to working with persistent classes right out of the box.
Use cases

When hovering over a method call in a CLS file, I can use the F3 as a shortcut to open the source code of the class being called.

Why cannot I not do this from within a script section in a CSP file?

Does developing a RESTful API in Caché remove the requirement to use the InterSystems.Data.CacheClient.dll and generate proxy classes using the Caché Object Binding Wizard for .NET web development? If anyone has links to sample applications using .NET with Caché and REST Services, I would be grateful if you could share them.

Last time, we stopped on static stuff. Let’s continue...

Hello,

I'm using Cache 2016.

I try to get a property set in my server response header.

I tried to get it in %request and %response but without success ...

Some one have an idea ?

Here an example of what i try to get :

Thank you

Hi guys,

I am using the %Net.HttpRequest method to get data from a server.

The server will continuously send data. Is there any way that i can able to read the HttpResponse data line by line so that if at a particular line i may terminate the request.

Please advice.

Thanks,

Arya

Set httprequest=##class(%Net.HttpRequest).%New()
	Set httprequest.Server="www.intersystems.com"
	Do httprequest.Get("/")
	Do httprequest.HttpResponse.OutputToDevice()
	Do httprequest.Get("/cache/")
	Do httprequest.HttpResponse.OutputToDevice()

The above is the code which i found in this link http://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?… 
How do the above code works and can i be able to run this?

Thanks in advance.

In our last lesson, we implemented a new REST Service to allow us to perform CRU operations on Widgets, and refactored our Controllers to allow the page setup to be decouple from the content.

Hi Guys,

I would to know, I have a drop down list items in my applications. While, am clicking on the drop down bx, there are few numbers of listed items, while am doing mouse over action, I should display the entire text of selected item from that drop down list box, even am not selecting that item. I would like to know about the what is exact text it contains in Zen framework. 

If any lead would be appreciated. 

Thank you in advance. 

Hi All,

Does anybody has experience with Angular application and have implemented some solution in order to track and record pageviews?

We are interested in to know how to capture those pageviews information and call a Caché REST Api in order to store those data.

Thanks.

Hello,

I am using CSP:search and would like to customize the appearance of pop-up search page with CSS.  Any help is appreciated.

Thanks.

Looking at the documentation expalining the use of client side menus, including the drop down menu.

I was messing around trying to get the "Open", once clicked, to use javascript to open windows file explorer to open/pick a file.

I've got it to partially work... Using keystrokes Ctrl-O will open the file explorer yet clicking on the drop down's File/Open does nothing.

Not sure what I'm doing wrong here.

NOTE:  I had commented out the two &html lines in the Testing Method... and doing a Ctrl-O still work.

Why?

(I am new to this language) I have got a JSON request to handle in a web application which is in %CSP.Request object. But the request which I am going to handle is of type array of objects.

Hi Guys,

I've a working that sent Http request to a REST API and is working fine,

Set Body = ##class(%ZEN.proxyObject).%New()Set Body.ElectronicMailAddressT = "ElectronicMailAddressT"Set Body.TelephoneMinimalN = "TelephoneMinimalN"Set Request.ContentType = "application/json"Set Request.Https=1Set Request.SSLConfiguration="TLS"Set Status = ##class(%ZEN.Auxiliary.jsonProvider).%WriteJSONStreamFromObject(Request.EntityBody, Body)Set Status = Request.Post(,2)

but now I'm looking to basically add an array or data inside the body so that it looks like this:

Let’s continue our series of articles about creating a web application using REST only.

Integration with jQuery EasyUI (using datagrid and tree components as examples)

I would like to write some code to parse a set of HTML pages from the internet in order to gather information from each web page.

All of the web pages are generated using a template, so the format of each of the web-pages is consistent with one-another and the information that I want to gather is always located in the same logical place within the page.

What is the best way to parse an html page in order to gather information at a specific place?

Can XML XPATH be used here?  Does anyone have any examples of parsing HTML content?

... but let’s first take a look at two relatively small topics, and namely:

Creation of a multi-page REST application

We only have one page for now. How about adding one more? Said - done.

Hello I'm Minsu

I want to develop web program like community with Spring Framework and Caché. but I have experience only with MySQL.

A. Can I use Caché with Spring Framework?
B. If I can, How? 

Thank you guys.

Hi, Community!

In the second part about DeepSee Web, I’ll describe what customization options you have with DSW.  

There are two types of customizations: widget customization and dashboard panel customization.

Example of dashboard customization on Developer Community analytics.

... but let’s first look at error handling.

We have an web application accessed using https, that uses CSP technology with frames.

The initial 'login' is via a single CSP page, which then redirects to another CSP page which creates the frames (4 in all) and loads a CSP page in each of those.  For the most part the frames load without error, but sometimes when logging in and sometimes while using the system ' 5916 Illegal CSP Request ' errors occur.

I say 'login' in inverted commas as a Cache login is not performed just an application login, I don't know if that's relevant so thought I'd mention it.

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
