Cache tricks

Several years ago, long before Developer Community Portal was launched, I published a series of Caché tricks at one of Czech web sites. In this article, I’m posting translated version of one of them.

Capturing output of someone else’s methods or routines

Suppose you, or someone else created a useful method or routine, that was producing some computation that you’d like to benefit from, but the routine was writing output to process principal device.

You would like to use the data, but you need it not written to a device, but assigned to a variable. And, for any reason, you can’t modify the code. What can you do?

Customer is using an ancient MSM based client Workstation for their application and they made a small change to their server code. They introduced property of %Double() and discovered an issue. The MSM workstation is not able to retrieve any property of an object instance that holds value of $double(0). see images illustrating the issue.

I'm posting this to DC intentionally before I eventually send it to WRC so others can comment.

this is catching me all the time, again and again...

Haven't worked with XML VDOC for some time, I can't figure out, what is the correct way of using Property path. Can someone please help me to refresh my memory.

Simple example: I have a class called Body, with Value and Topic properties. I created a XML Schema for this class and imported it into Ensemble. So i have a category called message, with Body as DocType structure and Name and Topic properties of Body complex type ($2:Value and $2:Topic are element names)

My rule looks this way:

Hello,

is there any API available that would return an MDX query string for a given saved pivot name? I could not find anything except for pivots with manual MDX. But that's not my case, I need to get MDX for any pivot.

TIA!

Presenter: Dan Kutac
Task: Use a common login identity and a central mechanism of authentication across environments from multiple entities
Approach: Provide examples and code samples of an application environment using OpenID Connect and OAuth 2.0

Description: In this session we will demonstrate an application environment using OpenID Connect and OAuth 2.0. Hear how this is done and what options you have; and yes, you get to keep the code.

Problem: How to use a a common login identity (e.g. Facebook credentials) and a central mechanism of authorization cross environments from multiple entities.

Solution: Create awareness and interest in using OAuth 2.0

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!

Hello,

Thank you!
