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.
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.
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.
Sometimes when I have Zen page in a browser (e.g. Management Portal page) and when my Internet connection interrupts, I see the alert window on the page, something like this screenshot:
Is there any setting for the CSP web app to prevent this alerts from popping up?
I'd like to have an array as a parameter for a SQL 'WHERE... IN' statement. The array would be modified in javascript on the browser. Here's a simplified example:
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.
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).
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
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 .
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.
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.
I'm having odd behaviors on my EC2 hosted IRIS Community instance.
When I configure a "custom login page" in the System Management Portal for my web application I'm seeing a few different behaviors that are under documented (and also undesired)
I am trying to disable a button on a JQM application.
I started the button as disabled according to this code: {type:'$button',caption: Button',key:'button',disabled:true}
However, I would like to enable or disable the button via JavaScript code . I have tried the following, but it don´t have the same behavior and style as the code above.
var view = zen('mainView'); view.disableItem('button',true,0);
Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.
I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.
- This can be slow/bad in applications with large data?
- It's better/recommended to use ZenReports even with ZenMojo applications?
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
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)
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.
Maybe someone has a logger for incoming CSP requests and willing to share? Debugging high traffic HTTPS application and wireshark just doesn't cut it sometimes. So I thought I'd ask here. I'm especially interested in getting raw stream of incoming request.
