Hey Community,

Watch this video to see how to connect to InterSystems Cloud Services from your .NET application using the InterSystems ADO.NET Managed Provider:

⏯ Connecting to InterSystems Cloud Services with .NET

I have updated some legacy VB/ASP.NET code and changed the references of InterSystems.Data.CacheClient to InterSystems.Data.IRISClient.  I am struggling with the code as I am not a .NET expert and there is little or no documentation.

I have published the code on several test IIS sites and on some the code works fine but on others I get the below error.  The error doesn't appear to be O/S specific as I have it working on some Windows 2016 servers and not working on other Windows 2016 servers.

I am using the %Net.HttpRequest class to download a file from the internet .using the following code. When a file is returned in the DOM I am able to read the file content and save it to the desired location but when my response is a download dialog nothing is returned in the HttpResponse. Am I doing something wrong here is where I have gotten to so far any help appreciated.

current code

Set httpRequest = ##class(%Net.HttpRequest).%New()Set httpRequest.Server = "msedgedriver.azureedge.net"
set httpRequest.Port=443
Set httpRequest.ContentType = "application/octet-stream"
Do httpRequest.Get("/113.0

Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.

There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.

But with IRIS, we

Hi Developers,

See how the Production Extension framework (PEX) allows you to build custom interoperability components in .NET or Java without first learning ObjectScript.

With PEX, you can code in a familiar language and take advantage of established code libraries to add components to a production.

Hi

I am upgrading our application from dotNet Framework to dotNet Core.

Prior to the upgrade I was able to connect to both my Cache & IRIS instances using the IRIS ADO.NET driver.

However, in dotNet Core, whilst I can connect to IRIS, I get the following error connecting to Cache.

InterSystems IRIS Provider is not compatible with Cache xDBC server
 

I am using the IRIS  driver from the Windows (x86-64) 2022.1 distribution (the one in dev\dotnet\bin\net5.0).

The cache version is Cache for Windows (x86-64) 2018.1.2

Thanks

I try the 2021.2 2020.2 , they own have this issus

For this issus i have submit to dotnet , hope they can solve this or find the reson for this and solve this.

ubuntu using unixOdbc dirver

Describe the problem you're observing:

using dotnet nuget System.Data.Odbc to connet the iris for some sql will have bug on linux,but it is ok on windows
and that driver is ok for other db type .
I have put a issue on dotnet also (dotnet/runtime#80015)
Is anyone can have a look for that

Integrating Cache with .net may be difficult, as we need to know both technologies and tools involved. Let’s follow the simplest possible example and see the pitfalls lurking on our way.

1. Creating .Net Assembly

.Net assembly is unit that contains compiled code and other resources.

Let’s create the simplest .Net assembly that will contain the code we want to execute.

We will use assembly of type Class Library, as we will use classes and their methods contained within. This type of assembly has .dll extension.

For this the easiest way is to use Visual Studio 2015, you can use free edition.

Hello,

I'm inserting a row using an insert statement from dotnet InterSystems.Data.CacheClient.CacheCommand.

Is there a way to get the inserted ID or IDs if I've inserted multiple rows?

Introduction {#Webinar:ImplementingIntegrationswith.NetorJava-Introduction}

InterSystems IRIS 2020.1 includes PEX (Production EXtension Framework) to facilitate the development of IRIS Interoperability productions with components written in Java or .NET.

Thanks to PEX, an integration developer with knowledge of Java or .NET can benefit from the power, scalability, and robustness of the InterSystems IRIS Interoperability framework and be productive in no time.

For an IRIS Interoperability framework expert, PEX makes it easy to enrich integrations with pre-existing Java- or .NET-language external

Hi, I tried the following exercise from the IRIS documentation. I updated the username, password and IP address, but receiving this error;

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. --->

I can use the same credentials and IP address to connect ok via VSCode to my local IRIS...

Any pointers much appreciated.

Hello,

I have an error connecting the InterSystems cache with the odbc driver with the ODBC-2017.2.2.865.0-lnxrhx64.tar version using the ubuntu versions 20.04 and version 18.04 (which works with the .Net Core 3.1 version) with the Net 6.

Hello,

Using ^TESTGLOBAL as an example, if my data structure is as follows:

I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute. 

Example:

Below would be the _sqltext

DECLARE @Id INT;

select id into @Id from something;

 if @Id = 9 

BEGIN

do something

END

The _sqltext would work in sql server, what would be the equivalent for cache for it work?

I get a generic error when I try it with cache

using (var mdscmd = new CacheCommand(_sqlText, MyConnection) { CommandType = CommandType.Text }) {

}

Thanks

I'm building a .Net Core Gateway container. Here's the issue.

As a final step I'm building a .Net Core 2.1 library. It has a runnable dependency - .Net Gateway, which I need to start first.

However dotnet publish generates .runtimeconfig.json and .deps.json only for my library and not for my dependency (.Net Gateway).

Is there a way to force dotnet to generate .runtimeconfig.json and .deps.json for a dependency?

I have tried:

  <PropertyGroup>
    <GenerateRuntimeConfigurationFiles>true</GenerateRuntimeConfigurationFiles>
    <GenerateDependencyFile>true</GenerateDependencyFile>

Hi guys,

I'm starting few POCs to test InterSystems IRIS with a .Net core backend of an API Gateway and I have few questions about this integration.

• Which .Net library is the oficial? 
  • I found at least 3 options: packages from nuget website (https://www.nuget.org/profiles/InterSystemsCorporation - that I couldn't do them work), packages “IRISProviderCore.1.0.0.nupkg” and “IRISXEPCore.1.0.0.nupkg” inside “IRIS\dev\dotnet\bin\CorePackages” (Iris installation folder) and libs “InterSystems.Data.IRISClient.dll” and “InterSystems.Data.XEP.dll” at github sample project

Hi

we are trying to call a Webservice that is hosted on a Ensemble production from a .net program.

The web application in ensabmle is defined with password authntication 

we can't get to set the security header in the .net program  (<soapenv:Header> ... <wsse:Security ... <wsse:UsernameToken  ... ) in SoapUI we added the Wss usertoken and it worked like a charm.

Doe's anyone have a idea to guide us? (links,  ,samples, etc. )

Thanks

We've repeated this one in Test, so I like making this inquiry - not that I comprehend it or anything. ;- ) 

WebMethods is interfacing with an IIS Web Service (I'm the IIS fellow, and the WebMethods fellow has no response for me.) IIS is tossing 200 0 1236 mistakes on a large portion of the calls, however.The reason for that is Timer_MinFileBytesPerSec.WebMethods is content with the outcome IIS sends, and doesn't generally close the system discussion amenably.This isn't an issue until the point when we get two brings in flight in the meantime.

Hi!

I'm trying to connect to one of our Ensemble servers Cache database from a C#-windows form . I'm running the client from my local computer with OS win7.  Using .NET FW ver 4.5.2 in the client.

ODBC local setup using "InterSystems ODBC35"

In this ODBC konfigurationview i can put my userID and password and try a testconnect (or ping). And that run successful.

However, we don't want to leave credentials in the ODBC-configuration it self (open up for anybody to use the source) but instead send it from the klients.

I have try all three ways from https://www.connectionstrings.com/cache/ and they all

I am surprised with the performance (poor) of Native API for .NET

       Following code (where ^testGlobal,node1 has 50 records) takes 5 seconds to run.  Anyone else think there is room for the improvement? 

    string global = "^testGlobal";
            object[] Subs = new object[1];
            Subs[0] = "node1";

            try
            {
                IRISIterator iter = iris.GetIRISIterator(global, Subs); 
               foreach (var item in iter)
                {        
                    Console.WriteLine((string)(iter.CurrentSubscript));
                }

I'm using this Dockerfile to build .Net Gateway with my PEX BS. It works fine. If I change the image reference here to store/intersystems/iris-community:2021.2.0.617.0 in line 8 (so update from 2020.2 to 2021.2) it fails to build with:

KafkaConsumer.cs(4,20): error CS0234: The type or namespace name 'EnsLib' does not exist in the namespace 'InterSystems' (are you missing an assembly reference?) [/source/KafkaConsumer.csproj]

KafkaConsumer.cs(9,34): error CS0246: The type or namespace name 'BusinessService' could not be found (are you missing a using directive or an assembly reference?)

trying to lock a table via .Net Command results in IrisExcpetions no mater what i try; 

Documentation says the Command is supported by TSQL Implementation - any known tricks how to implement this comand?

I'm attempting to use the .NET Entity Framework provider that is provided by InterSystems (see: https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GBMP_eframe).  In our environment, the "Support Delimited Identifiers" option is turned off and we are not allowed to turn it on without significant testing effort.  When this setting is off, the SQL that is generated by the Entity Framework provider is not considered valid and therefore the provider doesn't work (it DOES work, however, when this setting is turned ON).

Do you know of any way to work around this issue?

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon?  At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

 Native API  , IRIS 2019 regression vs Cache .Net provider 

1. checking the native API, with .net provider, from IS docs, I realize,

that it is not possible to wrap objectSricpt Class with .NET (C# for example) pure Class with it's methods/properties

and make pure instance syntax of: new myNetClass - as wrapper of irisClass.

as I realize, you can run  .Net Class , only with .Invoke or iris.ClassMethodVoid("class.name","method")

such syntax, cannot execute event driven on proprety change, let say, with it's build in mechanizm in .Net

2. IRIS 2019.

this version is missing the class IRISObject  ?
