NewBie's Corner Session 14 Inline Do & Nested Do with Implied Quit and For Loop

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

InterSystems Caché provides a GUI (Graphical User Interface) based Integrated Development Environment (IDE) called Caché Studio. Developers can use Studio to create and maintain applications.

The following concepts of Inline Do, Nested Do, Implied Quit and For Loop is difficult to explain in a manner that everyone understands. However, these concepts work well with each other.

Hi all,

          Is there any possibilities to set the null password for user account in cache 2016?

Thanks,

In our last lesson, we added a form to Edit our existing Widgets, and save them back to the server.  However, our Form was not well strcutured and our Save button had no intelligence, and was not fully visible.  So today, we will apply some Material components and Angular style to make the form more useful

Let's open EditWidget.csp, and make some changes.  First, we want to change the component from an md-card to an md-dialog.

This code snippet uses GZIP to compress and decompress a file in the file system. Change default file paths to customize code to compress/decompress your files:

Class objectscript.GZIP Extends %RegisteredObject
{
	classmethod test() {
		//Export Global(s) uncompressed
		set filename="C:\Temp\myglobal.xml"
		do $System.OBJ.Export("^oddEXTR.gbl",filename)
		//Open exported Globals
		set uncompressed = ##class(%FileBinaryStream).%New()
		set uncompressed.Filename=filename
		Set compressed = "C:\temp\mycomglobal.xml"
		//Open File Device over Gzip and Copy Uncompressed information to it
		Open compressed:("WUNK":::/GZIP=1:/NOXY=1:/OBUFSIZE=32768):0
		Use compressed
		do uncompressed.OutputToDevice()
		close compressed
		//Create New File  
		set out = ##class(%FileBinaryStream).%New()
		set out.Filename= "C:\Temp\decomp.xml"
		//Open compressed File and save information uncompressed over gzip
		Set file=##class(%File).%New(compressed)
		Do file.Open("RUK:::/GZIP=1:/NOXY=1")
		while ' file.AtEnd
		{
		    set line = file.ReadLine()
		    do out.Write(line)
		}
		do out.%Save()
	}
}

Hi All, I am taking a namespace and routines from one table for particular user.if the user have name space and routine means it execute well but after executed the routine it is automatically quit and close the session.I need to keep the same namespace after executing the routine.

Currently we have a setup where we have an external IIS webserver that our CSP Gateway sits on that routes requests to our ensemble server. When working with soap everything was routed to the CSPms module since the site's handler mappings have *.cls going to this module. However, now that we are working with rest services that don't have a file extension we will have to have all traffic on the IIS box be routed through the CSPms module. 

I was curious if anyone has encountered this type of issue, and if so, what steps did they take to resolve it?

Configuring Java with InterSystems Technology

Regardless of what InterSystems technology you use to design your applications, it is likely that some of our product functionality will require that Java be installed on the operating system, and subsequently be configured properly with your InterSystems based application. There are many ways that this can be accomplished depending on your operating system, as well as the specific InterSystems technology you are integrating with.

AI can be categorized in any number of ways, but here are two examples.

The first classifies AI systems as either weak AI or strong AI. Weak AI, also known as narrow AI, is an AI system that is designed and trained for a particular task. Virtual personal assistants, such as Apple's Siri, are a form of weak AI.

Strong AI, also known as artificial general intelligence, is an AI system with generalized human cognitive abilities so that when presented with an unfamiliar task, it has enough intelligence to find a solution.

As you know, Caché can be used as a relational DBMS working with JDBC/ODBC drivers and supporting the execution of arbitrary SQL queries and SQL procedure calls. 

We also know that Caché stores all the data in multi-dimensional sparse arrays called globals. It allows the developer not to use the standard CachéSQL engine in case a particular SQL procedure is underperforming, but instead rewrite its execution code in the Caché ObjectScript (COS) language intended for server-side business logic. This approach may help implement the optimal SQL procedure execution algorithm by using better-optimized NoSQL data structures (globals).

However, the standard class library in Caché has one limitation: for SQL procedures where data selection is controlled by custom COS code, you need to define the set of returned fields at the compilation stage - i.e. it is impossible to dynamically define metadata for an SQL procedure working with NoSQL structures. This article is about how to get around that limitation.

Hi,

I would like to list out unchecked mapped items ( classes in management portal )  classes of a particular namespace. Is there any code or terminal command which i can use ?

I am able to list out classes of namespace . But I need to list out unchecked mapped items classes

do ##class(%SYSTEM.OBJ).GetClassList(.result)

Embedded SQL is a tool that allows us to execute SQL statements in Caché Object Script. For example, to select the name of a person with a particular SSN from the Sample.Person class

The colon syntax is used to identify local variables, in this case tName and tSSN. &SQL indicates to our compiler that this is SQL syntax. At compile time, this statement will be optimized to executable Object Script code. More about this syntax can be found here.

Good morning, I am using a <Image/> tag, in a <Tab/> tag, of a <TabGroup/> to render a tif image. I would like the tif file to be rendered full size. However, I have not been able to achieve this using the height="100%"  and width="100%" parameters available. All I get is an envelope with scroll bars, with perhaps a quarter of the image visible at any one time. Thank you in advance for any and all feedback.

Question

 What version of Caché supports TLS v1.2? 

Answer

Caché uses the openssl library for SSL/TLS support.  On Windows, Linux and Unix, a version of this library is included with the install kit.  Caché 2014.1.3 and 2015.1.0 ship with the openssl 1.0.1j library.  TLS v1.1 and v1.2 support is first available in openssl version 1.0.1, so Caché 2014.1.3 and 2015.1.0 are the first versions to allow the use of TLS v1.1 and v1.2.

On these versions, if the "TLS v1" checkbox is checked in an SSL/TLS configuration, the system will use any of TLS v1.0, v1.1 and v1.2 .

Hello,

I'm just re-going through the Caché foundations course exercises using a copy of Try-Caché on my home pc.
