Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.

We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

Hello everyone,

I just want to know if there is a difference in performance between using Class methods versus MAC routines?

For example:

do Method^MyFunction()

versus

do ##class(MyFunction).Method()

Applying Stylesheet

Hi Guys,

I'm using the below style and everything looks good, with my Dynamic Grid width 1300px, but when I refresh my grid the width goes out of whack and the grid is too wide, so how can I re-call my enforce my style to be applied again after refreshing my grid, so basically I'm looking for a line of code that I add it to my refreshing () clientMethod ?

XData Style
{
<style type="text/css">
body {
padding: 5px;
margin: 0px;
height: 100%;
background-image : url(images/bkground.gif);
}

Hi Community,

I have a CSP page I am developing with the intent of pulling files from an SFTP site and placing them in a folder on the local network.

I am having an issue where the CSP page is catching a JS error. The error in the browser is - A JavaScript exception was caught during execution of HyperEvent: SyntaxError: Unexpected identifier 'downloading'. (However, the unexpected identifier changes after refreshing page, or after removing the Write statement with the work 'downloading' in it.)

I think I have narrowed it down to a piece of the Javascript code -

Hi

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

Hello,

I need to create a dialogbox on my zenpage to confirm a Delete operation.

I tried using below code on in a my client side method but its creating a blank dialog box.

zenLaunchPopupWindow('%ZEN.Dialog.confirmationDialog.cls','confirmationDialog','resizable,width=380,height=180');

Is there a way i can create a Dialog box with text "Do you want to delete" and two buttons "Yes" and "No" and store the response in the calling client/server method.

Thanks,

Jimmy Christian.

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

Ok, I am attempting to clarify the required use of the RESIZE command, when you have a UNIVERSE or a UNIDATA DB attached to Cache. Traditional UNIVERSE / UNIDATA databases 'require' that hashed files be re-sized according to historic use, to prevent file overflow (aka. performance issues). It is not clear if that requirement is fully eliminated by attaching one of these databases to Cache. It is clear that, if you do not allocate 'enough' space on Cache for the database 'as a whole', that is a problem.

Hi everyone.

I have a function that may end up being called from a number of transformations at the same time, and within the function there's some Embedded SQL to first check if a local table has an entry, and then adds the entry if it doesn't exist.

To prevent a race condition where the function is called by two transformations and they both end up attempting to insert the same value, I'm looking to use the table hint "WITH TABLOCK" on the insert, but this seems to be failing the syntax checks within vscode.

Are table hints supported with embedded sql?
