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.

Hi,

I sometimes get asked if Weblink will still be available (as a downloadable ad-on these days) for some versions to come.

I realize that this is old technology now, and that there are better and faster ways to do the same things today.

Thanks

Caché Localization Manager

CLM is a tool for localization/internationalization/adding multi-language support to a project based on InterSystems Caché.

Imagine that you have a ready project where all the content is in Russian, and you need to add an English localization to it. You wrap all your strings into resources, translate them into English and call the necessary resource for Russian or English when necessary. Nothing tricky, if you think about it. But what if there are lots of strings and there are mistakes in Russian (or English)? What if you need to localize in more than one language – say, ten? This is exactly the kind of project where you should use CLM. It will help you localize the entire content of your project into the necessary language and retain the possibility to correct entries.

Hello,

One of our AP would like us to provide the file upload/download sample code by using ZEN Mojo.

I already provided them the attached "upload-sample".

I tried to create the "download-sample" in a similar way, but I couldn't do it yet.

Does anyone have a good idea/sample about this?

I'd like to download the server side file(e.g. c:\temp\nene.jpg) into client machine with a OpenFileDialog(image.png).

Thank you in advance.

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.

Hello, our customer, large industrial company, is considering modernizing their old CSP application so it can run on multiple client device types, using responsive design.

They have a lot of experience with CSP and some ZEN.

They are new to REST and have some limited knowledge of javascript - perhaps not enough to the extent used by client framework.

Does anyone have a framework or a set of templates that you would be willing to share?

Thank you!

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.

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

Question

How do I free licenses?

I have a server with public web application with Unauthenticated access and there seems to be a problem that CSP session ends, but associated license persists for some time (hours). If several users log in, we can hit license limit and all the other users get 503 Service unavailable error.

We are currently debugging it and moving to authenticated web applications, but is there a way to free these licenses quickly?

Here's how it looks like in SMP:

I've noticed that Management portal somehow manages to allow a single user to be in different namespaces in different tabs in the same application (i.e. Management Portal). I've looked at my Processes, however, and see that all of my processes using MgmtPortal think I'm in %SYS, even though 2 of them are looking at globals in two different namespaces; NamespaceA and NamespaceB.

I can even fool MgmtPortal because the first time I try to look at a global in NamespaceA it thinks I'm in %SYS! After a refresh, however, I can see the global in NamespaceA.

We are trying to understand how websocket connections from a javascript client may timeout in cache. Does anyone know if and of the session timeout or any other timeouts apply to any synchronous websocket connections? I have not been able to prove that they do timeout at all.

Hi,

posted some weeks ago in the "old" ZEN Google Group, maybe someone here can help to understand how to properly setting up a csp applications and contributing from the build-in caché security mechanism.

I´ve created a webapplication and wan´t to add further security to it using the smp. But... first things first.

I have two Databases let´s say DB1-LOGIN and DB2-Application. Each of this DBs has a resource assigned. DB1-LOGIN has a resource %DB1-LOGIN which has a public permission of 'read'. DB2 has a resource as well %DB2-Application with no public access.

If I wanted to build a web-based dashboard that monitored various HIE transactions where would I start?

Examples of measures would be Provide & Registers by Facility, Patient Views by facility or even PHR related data.

I have a successful POC that uses nodejs, html and SQL but I think it makes more sense to use Intersystems technology all the way around, I just don't know where to begin.

I am going to start playing with Zen Mojo (again) and as I understand it there are two ways to manage moving data to/from your Zen Mojo page:

  • interacting with REST services
  • using Mojo's built-in transport

I would like to understand the pros and cons of each approach. Which is recommended in different situations and why? I would like to create a sample application that will hopefully be reusable and helpful to others and I would like to understand which approach to pick for my app.

Is there a possibility to map a CSP page residing in namespace ABC to a namespace XYZ so you could access it as if executing from XYZ: http://localhost:57772/csp/xyz/MyPage.csp ? Some odd cocktail of web application and package mappings that could make this happen?

The idea is to keep the CSP page in sort of a read-only namespace that only contains code, with the data residing in another namespace. This works for zen pages, but not for CSP.

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?

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,

I want to create a table with a dynamic display of data using the DataGrid.

On the page there dataCombo and the table.

According to the plan, when the user selects an item in dataCombo the table is filled with data. If select another item - data is updated.

But in fact, the data in the table are loaded once when the page is loaded, and when I select value in DataCombo, I receive an error:

Hi -

I'm trying to figure out what is the best (or at least pros & cons) on how to manage login accounts in a multi-tenant SaaS web based application context.

Assume that a company is designing a collections of web based applications that they will be selling as "services" to their clients, and that these clients will each have their own "users" and "customers" that will be logging into these services.

Presenter: Danny Wijnschenk
Task: Build a development stack that enables state-of-the-art rapid development with a stable but adaptive back end.
Approach: Use InterSystems’ new document data model to achieve modern full-stack development

The MEAN stack is a very popular stack for building applications quickly that can change at a rapid pace. We will explore the benefits of such a stack and how you can tackle the requirements for modern and fast paced front-end development with support of a stable, but yet adaptive back-end using our new document data model.

I have a ZEN page with buttons, text boxes and a tab group. The tab group contains a single tab which I use to display an image(src). When the user, uses the browser zoom capabilities to reduce or enlarge the image, the other controls are reduced or enlarged as well. How can I reduce or enlarge the tab src alone? Thank you for any and all input.
