The purpose of this post is to raise the profile of a powerful mechanism that has long been available to us, and to open a discussion about ways in which it can be used or abused.

You can read more detail about the mechanism here. To summarize, your class definition can use the Projection keyword to reference one or more projection classes. A projection class can implement methods that get invoked at key points in the lifecycle of your class.

Hi Guys,

for some reason the height in my tablepane are very big, how can I adjust the height in the rows in a tablepane?

Thanks

Are there any direct command to find the length of subscript of global variable? Is it possible to code in objectscript to find the maximum length of subscript in a global variable.

Besides objectscript's own list, array data structure, are there any other data structures that have been implemented, similar to the "collection" package in java, or is there a ready sorting tools for the collection class.

Hello, everyone,

I'm trying to find solutions to a problem that's becoming quite boring.
On only one namespace, the sudio is very slow.
The studio freezes completely for 5-10 seconds when I save or compile a class. Sometimes it also freezes for no apparent reason at a random time...
It stops when I change namespace...

Do you have any idea what that could be?

Thank you in advance

I am getting the following error when trying to fect data from DeepSee:

"Error":"ERROR #5002: Cache error: <PROTECT>%Construct+3^%DeepSee.ResultSet.1 ^DeepSee.Cache.LocalResults(\"session\"),e:\\hs-db\\tfoms\\"

However, I cannot find the place this error points me to.

Specifically, it says 'Label %Construct + 3 lines, in the %DeepSee.ResultSet.1', but there does not seem to be such a place. I could only find the %DeepSee.ResultSet class and it does not have a lable named %Construct.

gj :: locate was the entry from George James Software for the Developer Tools competition back in April 2021. When an ObjectScript error is reported, gj :: locate takes the .int line location and navigates you directly to the line in the source file where the error originated. Over the past few months we've found it a very useful tool when it comes to debugging, especially when used alongside the Serenji debugger in Visual Studio Code.

Our first update, version 1.1.0, now includes support for multi-root workspaces. This enables gj :: locate to be used with every workspace folder. If your VS Code workspace has more than one root level folder, connecting to different namespaces or perhaps different servers, then gj :: locate will determine which workspace folder is current and locate the source code in that folder. If your workspace doesn't have any files open then gj :: locate will prompt you to select a folder from a pick-list.

This will particularly benefit VS Code power users who have workspaces with simultaneous connections to multiple namespaces, on multiple different IRIS and Caché servers.

If you would like to try it out then you can download it from the VS Code marketplace. Or if you’re already a user, then gj :: locate will automatically update. Let us know how you're getting on with it!

Here are a few examples of conversions and operations you might need, along with links to documentation where you can learn more.

At the time I wrote this, Eastern Daylight Time was in effect for my Caché system.

How Caché keeps the time and date

Caché has a simple time format, with a longer range of recognized dates compared to some other technologies.

The current time is maintained in a special variable $HOROLOG ($H):

Hi everyone,

I am talking from Brazil and we have one very important customer that requested our support to find a consultant, deeply specialized in Cache that could work with us attending this customer. It has a tons of data and its core application is based on Cache.

If you are interested send me an email with the subject title - Cache consultant opportunity - and we will make contact with you. The main request is how strong are your skills in cache and it would be considered a differentiator if you are a portuguese speaker.

Hi,

I have the requirement to dump large result sets into files. I am currently using %SQL.Statement and the result set created by it.

The DisplayFormatted is used to write a CSV. The query I used to test does not contain any filters, it is just a select * from a table with 16 million rows.
The file created is 2GB in size. The issue I have is that it takes 8 hours to create this file.

We’ve published an update to the Serenji debug extension for Visual Studio Code, making it ready for the Workplace Trust feature in VS Code 1.57.

This allows the Serenji ObjectScript editor to work without restrictions across all workspaces and, by bringing it in line with the VS Code update, only allows the debugging feature to be used in trusted workspaces.

Some key points are emphasized in this article in order to save your time to get linux ldap client in cache working with windows AD (active directory) LDAP server.
The first thing to do is to get successful TLS connection to windows AD.
Raw tcp case is beyond of this article, there is no problem with it, it is trivial.
Windows ldap server uses port 636 for tls and this port can be used to get ldap certificate.
As we will see later there is reason for this.
linux ldap client uses STARTTLS special ldap extension to switch plain tcp to TLS only.

Difference between DO and JOB command and practical use of job in objectscript??

What is the syntax in Zen PDF Reports to form feed between tables?
