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?P...

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 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 have a property which I need to move from one class definition to another as follows:

Old definition:

Class SCHED.SchedEntry
{
  
  Property Experiment as %String;

  Property ScanSlot as list of TracerEntry;

}

Class SCHED.TracerEntry
{
  
  Property Tracer As %String

}

I want to move the Experiment property to the TracerEntry class so that there is a different Experiment allowed for each ScanSlot, like this:

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 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?

Hello Community,

I recently encountered a issue with Caché and I can't figure out where the problem is coming from.

I noticed that the license limit (200)  was reached whenever I was opening my Studio (so it seems). When this occurs, I restart Caché (with the Cube in the Taskbar), and the number of license used is back to 1%, but grows back after.  The time taken before the number of license  grows back again looks pretty random.

Here is a couple of screenshots :

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.

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.

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

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.

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.

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.

Read the article here:
