Automatic Watch variables

I come from Visual Studio and now I use mostly Cache 2017 Studio. One debugging functionality I miss dearly is current local variables automatically appearing in the Watch Variables window together with their values. Yes, I can hover or type them myself but both actions take extra time which is especially noticeable when debugging unfamiliar code across many routines. Any Cache settings or plugins to that effect? If not then why not? And if nothing else is there in Cache, what are the alternatives or hacks in this respect?

If I open a terminal and type the following commands, sc is an error:

set validator = "sc = ##class(%Library.Numeric).IsValid(""BLAH"")"
set @validator
write sc

At the end, when I write sc I get:

0 L'BLAH9
             DOCXT010,#e^zIsValid+1^%Library.Numeric.1^1e^^^1

However, if I call the following class method using the arguments "%Library.Numeric" and "BLAH", sc is undefined

I searched to see if there was a previous question on this, but I didn't quite find anything. Please link if you think this has been answered before (I have a feeling it has): what are the barriers to source control using Cache 2018 and Studio?

version cache for windows, 2017.2.1 build 801_3 - windows 10

I had this system set up for 3+ years now, and background tasks such as converting emails, have always worked, suddenly it's stopped working and I've tracked it down to any network references.

reading the emails, I look for any attachment files, and save them to a network drive before processing them within a class method,

I've been testing it by sending exactly the same email repeatedly and checking the saving of the attached file in both the background and in the terminal.

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Since now i have been working from external connection but i want to work with the SQL utility of Management Portal

i dont know how to do with several instructions like in other editors like this example

update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '101' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '102' and Empresa = 'CO'

it returns

Hi guys,

How do you deal with underscore characters when using jsonProvider and exporting or importing ?

for example:

USER>s jsonString="{""what"":""1"",""up"":""2"",""test_test"":""3""}"
 
USER>set status = ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(jsonString,,.outputObj)
 
USER>w outputObj.what
1
USER>w outputObj.up
2
USER>w outputObj.test_test
 
W outputObj.test_test
^
<UNDEFINED> *test

we found out that we can access it like this, but not sure if it's the recommended method-

HI,

I have made a query with class definitions and all their properties and put them in a view.

All is good besides Parameters is showing junk characters. Is there a way to do it cleanly besides getting into the code??

SELECT
CC.ID As CompiledClass,
CC.SqlSchemaName,
CC.SqlTableName,
CP.Name As PropertyName,
CP.SqlFieldName,
CP.Type,
PD.Parameters

FROM %Dictionary.CompiledProperty CP
JOIN %Dictionary.CompiledClass CC
ON CP.Parent = CC.ID

Portal's category.

Hello,


I’m looking for a way to find out which category of portal a connector belongs to.
I looked at the class ‘Ens.Config.Production’ and ‘Ens.Config.Item’ but without success.


An idea about the ‘ObjectScript’ code to design?

Best Regards.

I've mapped multiple tables (UNION on mapped SQL classes) into a view, using CREATE VIEW.

Through ODBC, in Entity Framework, I am querying against that view and offering paging. The paging is implemented using IQueryable.Skip and IQueryable.Take.

Skip seems to have unexpected results, I believe due to incorrect SQL generated by the Entity Framework provider, though perhaps I've done something incorrectly. The generated SQL looks similar to this (with some bits replaced or altered for security reasons), the basic structure is unaltered.

Hello,

Last weekend we've updated our Caché version to

Versie:Cache for Windows (x86-64) 2018.1.1 (Build 312U)

I'm using Studio to develop. I've been using the built-in debugger and it has been working nicely. But now, since the upgrade, I'm getting this error when trying to debug any routine or class method:

Hello.

For debugging purposes I sometimes need to display stack information to the current device or save it (to a global for example).

There is this snippet offered in documentation:

ClassMethod StackToDisplay()
{
    For loop = 0:1:$Stack(-1) {
        Write !, "Context level:", loop, ?25, "Context type: ", $Stack(loop)
        Write !, ?5, "Current place: ", $Stack(loop, "PLACE")
        Write !, ?5, "Current source: ", $Stack(loop, "MCODE")
        Write !
    }
}

And to save stack to a global there's always an exception method:

Hi

I've got a Service that get ACK Messages originated by another system.

I want to get the details of a Message when the ACK is CE (Failed Message).

I don't know whether this is the best approach but, at the moment, I have a DTL and I would like to search the Cache Database for a Message with the Control ID on the ACK in the MSA segment.

Any help with this would be great.

Tks.

Hi,

So I am a front end developer working with REST API with Cache database on the BE. The BE guys are currently using Cache through a Windows virtual machine and they claim it is not possible to have a development server to work with. All the work they are doing is directly on the production server and changes are immediate and I think this is a bad idea going forward and we most definitely need a development server that has access to the same code base and different version (through git) to be able to do development. We also do all the testing on this production server with test accounts, but we cannot do automated testing with this setup.
