Front-end web development is the practice of converting data to a graphical interface, through the use of HTML, CSS, and JavaScript, so that users can view and interact with that data.

I have a query that I would like to have refreshing at certain intervals lets say every 30 seconds with out refreshing the page content using the META TAGS

refreshes the whole page but I have a jquery function that will run at those intervals that I can use the problem is getting the jquery to call my COS function or is the way to do it with pure COS

Hi-

I'm curious to know what InterSystems clients are using for csp based web development methodology.

Are you doing tag based development, or class based development?

If you are using tag based development, what tools are you using to create the look and feel of your web pages? Are you using tools like Adobe Dreamweaver, or do your developers sit down and code HTML using plain editors like Notepad and Notepad++

Are you doing prototyping of web pages and then adding CSP tags, or are you just developing the finished csp page with no prototype?

Hi,

Assume an architecture where an ECP Database Server is connected to by one or more ECP Application Servers inside a firewall.The application server hosts the web application that web users connect to.

The Web servers are outside the firewall, and, (using the CSP gateway/server mechanism) issue requests over the SuperServer port and into the application server.

I know that the traffic between the Web Server and the ECP application server can be encrypted using HTTPS, and access to the CSPServer on the Application server is username/password secured.

When refreshing a html or tablePane component using refreshContents() that takes a lot of server-side-processing, I'm running into timeouts every now and then. i.e., the result for the tablePane is that there's nothing displayed at all.

How can we configure (relax) that timeout so also those heavier ones get refreshed eventually? Just overriding %request.Timeout in %OnPreHTTP did not seem to do the trick.

I created a Zen page with a header. All is good. I then created a new Zen page and during the wizard specified that it was a "subclass of a template page". So now I have Class Custom.App.HomePage Extends Custom.App.TemplateMaster. If I visit HomePage.cls I see the header from the template. However, the HomePage class has no XData Contents section so I have no idea how to actually add content. I tried adding the section but once I do then I don't see the template content anymore.

Please consider these two concepts:

Concept 1 - Web Service or Web Application or Server Side

Concept 2 - Client Service or Client Application or Client Side

Maybe I am just a Web/Zen newbie, if I am and you all understand this, I apologize. (no nasty remarks please)

The questions are numbered, if you wish to respond to an individual question please precede it by the question number.

  1. Is there consistency in naming these concepts?

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.

Nested Tabs on ZEN component

Hi

I'm starting to play around with dynamically creating tabs and panes from query data, and was trying to do the following, with nested tabs.

Tab Group

High level tabs

Sub Tab Group

Sub tabs from the High level tabs.

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.

IRIS GUI/DTL Rewrite

Hi,

I've heard from two different sources the SMP (or parts of it) and for sure the DTL front end (in studio? via SMP?) have been rewritten to be more modern. But on a latest IRIS Community download everything looks the same to me. Am I missing something or is this Marketting Spin?

Hopefully I won't get banned for this post aswell......

Good afternoon, I have image files stored on disk. I would like to display those images in an <image> control as the end user clicks on rows in a tablepane. I already do this with image data stored in a cache database:

s imageComp = %page.%GetComponentById("ImgTab"_tLdCnt)
s imageComp.disabled=0
s tId=rsId.Get("ID")
s tPageObj=##class(My.PageObj).%OpenId(tId)
s oid=tPageObj.ImageBLOB.%Oid()
s encryptedOid=..Encrypt(oid)
s imageComp.src="%25CSP.StreamServer.cls?STREAMOID="_encryptedOid

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?

So I installed Atelier, created my project, imported and compiled all my classes but now I need to import all my CSP files too but I can't find any instructions on how to do so. Just copying the files into [project]\CSp\csp is not working as they don't show up in the project tree.

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 everyone!

I am helping a partner to develop a new application and one of the things we are facing is that this WEB application will be used on different time zones.

My first recommendation is that all timestamps should be drawn from $ZTimeStamp instead of $Horolog. That would allow the system to be draw the correct sequence of events even when they are generated on different timezones.

Hello Cache Developers! The purpose for this post is to outline a coding challenge that I have encountered when trying to use shortcuts (i.e. CTRL+G) within a ZEN application. Allow me to provide a summarized background:

Our application has a ZEN page (call it the PPL page) with a tablepane that displays a list of records. This page also has an iFrame (#1)
