Check for completed pipeline in Azure DevOps from WorkItem

For a project I'm working on I have to get a Pull Request and Repository from an Azure DevOps WorkItem ID.
I'm using the Microsoft.TeamFoundationServer.Client NuGet-Package for this.
Now i also want to be able to check if a build pipeline ran successfully before moving on to further steps.
After trying to figure it out myself and not finding a single article on how to do that, I'm just gonna ask the question myself.
So, I already have:
the WorkItem object
the GitRepository object
the PullRequest object
And I want:
some form of pipeline object of that specific Pull Request/Commit
I hope there even is a way to get that.
Any help or references are apprechiated. Thanks!

I'm working on I have to get a Pull Request and Repository from an
Azure DevOps WorkItem ID.
For pull request that related to work item, I can write a C# code for you. But for the repository, I think there doesn't have a relationship between repository itself and work item in DevOps concept(link commit and work item is possible.).
Now i also want to be able to check if a build pipeline ran
successfully before moving on to further steps.
Do you mean you want the pipeline run status related to pull request? I checked the sdk definition, there doesn't have such definition, also no in the REST API. A possible solution is following the f12 to capture the API to get the build pipeline run id and it status.
Just a demo:
using System;
using System.Threading.Tasks;
using Microsoft.TeamFoundation.Build.WebApi;
using Microsoft.TeamFoundation.SourceControl.WebApi;
using Microsoft.TeamFoundation.WorkItemTracking.WebApi;
using Microsoft.TeamFoundation.WorkItemTracking.WebApi.Models;
using Microsoft.VisualStudio.Services.Common;
using Microsoft.VisualStudio.Services.WebApi;
namespace GetPipelineResults
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
string url_string = "https://dev.azure.com/xxx/";
string personalAccessToken = "xxx";
Uri orgUrl = new Uri(url_string);
string project = "xxx";
int workitemId = 122;
var workitem = GetPullRequestAndRepositoryFromWorkItemId(orgUrl,personalAccessToken,workitemId);
var pullRequestUrl = workitem.Result.Relations[0].Url.ToString();
var pullRequestUrl2 = pullRequestUrl.Substring(pullRequestUrl.LastIndexOf('/') + 1);
string[] pullRequestUrl2Array = pullRequestUrl2.Split("%2F");
string pullRequestIdString = pullRequestUrl2Array[pullRequestUrl2Array.Length - 1];
Console.WriteLine(pullRequestIdString);
}
//Get Pull request from work item id
public static async Task<WorkItem> GetPullRequestAndRepositoryFromWorkItemId(Uri orgUrl, string personalAccessToken, int workItemId)
{
VssConnection connection = new VssConnection(orgUrl, new VssBasicCredential(string.Empty, personalAccessToken));
WorkItemTrackingHttpClient workItemTrackingHttpClient = connection.GetClient<WorkItemTrackingHttpClient>();
WorkItemExpand workItemExpand = WorkItemExpand.All;
var workItem = workItemTrackingHttpClient.GetWorkItemAsync(workItemId, expand: workItemExpand).Result;
return workItem;
}
}
}

Azure service bus subscription metrics

I am trying to find the best way to see the last date a subscription in a topic was accessed via c# (SDK or otherwise) i.e. to purge the queue if not accessed in over x hours. I know there is that functionality built into the service bus explorer but have not been able to find any SDK functionality. If anyone could point me in the right direction it would be appreciated.

Please see the code below. It uses Azure.Messaging.ServiceBus SDK. The properties you're interested in is available in SubscriptionRuntimeProperties class.
using System;
using System.Threading.Tasks;
using Azure.Messaging.ServiceBus.Administration;
namespace ConsoleApp1
{
class Program
{
static async Task Main(string[] args)
{
string connectionString =
"connection-string";
string topicName = "topic-name";
string subscriptionName = "subscription-name";
ServiceBusAdministrationClient administrationClient = new ServiceBusAdministrationClient(connectionString);
var result = await administrationClient.GetSubscriptionRuntimePropertiesAsync(topicName, subscriptionName);
Console.WriteLine(result.Value.AccessedAt.ToString("yyyy-MM-ddTHH:mm:ss"));
}
}
}

Google Vision API Document_Text_Detection

I am trying to develop C# Google Vision API function.
the code is supposed to compile into dll and it should run to do the following steps.
get the image from the image Path.
send the image to Google vision api
Call the document text detection function
get the return value (text string values)
Done
When I run the dll, However, it keeps giving me an throw exception error. I am assuming that the problem is on the google credential but not sure...
Could somebody help me out with this? I don't even know that the var credential = GoogleCredential.FromFile(Credential_Path); would be the right way to call the json file...
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Google.Cloud.Vision.V1;
using Google.Apis.Auth.OAuth2;
using Image = Google.Cloud.Vision.V1.Image;
namespace DLL_TEST_NetFramework4._6._1version
{
public class Class1
{
public string doc_text_dection(string GVA_File_Path, string Credential_Path)
{
var credential = GoogleCredential.FromFile(Credential_Path);
//Load the image file into memory
var image = Image.FromFile(GVA_File_Path);
// Instantiates a client
ImageAnnotatorClient client = ImageAnnotatorClient.Create();
TextAnnotation text = client.DetectDocumentText(image);
//Console.WriteLine($"Text: {text.Text}");
return $"Text: {text.Text}";
//return "test image...";
}
}
}

You just need to setup the environment variable GOOGLE_APPLICATION_CREDENTIALS as mentioned here

You mus have to mention you json file name in the environment variable as this.
Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", "Your_Json_File_Name.json");
Your code would look like this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Google.Cloud.Vision.V1;
using Google.Apis.Auth.OAuth2;
using Image = Google.Cloud.Vision.V1.Image;
namespace DLL_TEST_NetFramework4._6._1version
{
public class Class1
{
public string doc_text_dection(string GVA_File_Path, string Credential_Path)
{
//var credential = GoogleCredential.FromFile(Credential_Path);
Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", "Your_Json_File_Name.json");
//Load the image file into memory
var image = Image.FromFile(GVA_File_Path);
// Instantiates a client
ImageAnnotatorClient client = ImageAnnotatorClient.Create();
TextAnnotation text = client.DetectDocumentText(image);
//Console.WriteLine($"Text: {text.Text}");
return $"Text: {text.Text}";
//return "test image...";
}
}
}
or you can send it through your Credential_Path variable.
for more details please visit Google Vision API Docs

You need to setup your environment in your console with code like this :
Windows Server:
$env:GOOGLE_APPLICATION_CREDENTIALS="File Path"
Linux Server :
export GOOGLE_APPLICATION_CREDENTIALS="File Path"
Hope it helps!

Emotion detection from facial expression using google cloud vision api

I am going to compare some emotion detection applications. I want to design a simple C# application to test emotion for large number of images using build-in code or built-in libraries. Can we download c# code for emotion detection from google cloud api?

Yes, you can. It has two ways either parse json response or you can use following method of native c# code.
For more detail visit
https://cloud.google.com/vision/docs/libraries#client-libraries-usage-csharp
using Google.Cloud.Vision.V1;
using System;
namespace GoogleCloudSamples
{
public class QuickStart
{
public static void Main(string[] args)
{
// Instantiates a client
var client = ImageAnnotatorClient.Create();
// Load the image file into memory
var image = Image.FromFile("wakeupcat.jpg");
// Performs label detection on the image file
var response = client.DetectLabels(image);
foreach (var annotation in response)
{
if (annotation.Description != null)
Console.WriteLine(annotation.Description);
}
}
}
}

Why can't I read a db4o file created by a Java app in a C# app?

I have a db4o database that was generate by a Java app and I'm trying to read it using a C# app.
However, when running the following line of code:
IObjectContainer db = Db4oEmbedded.OpenFile(#"..\..\..\Databases\people.db4o");
I get the following error:
Unable to cast object of type
'Db4objects.Db4o.Reflect.Generic.GenericObject' to type
'Db4objects.Db4o.Ext.Db4oDatabase'.
Any ideas? I know there are person objects that contain personId fields (along with others) in the DB. I'm using db4o version 8. I'm not sure what version was used to generate the database.
The entire program is:
using System;
using System.Collections.Generic;
using System.Linq;
using Db4objects.Db4o;
using Db4objects.Db4o.Config;
using MyCompany.Domain;
namespace MyCompany.Anonymizer
{
internal class Program
{
// Private methods.
private static IEmbeddedConfiguration ConfigureAlias()
{
IEmbeddedConfiguration configuration = Db4oEmbedded.NewConfiguration();
configuration.Common.AddAlias(new TypeAlias("com.theircompany.Person", "MyCompany.Domain.Person, MyCompany.Domain"));
configuration.Common.Add(new JavaSupport());
return configuration;
}
private static void Main(string[] args)
{
IObjectContainer db = Db4oEmbedded.OpenFile(#"..\..\..\Databases\people.db4o");
try
{
IList<Person> result = db.Query<Person>();
for (int i = 0; i < result.Count; i++)
{
Person person = result[i];
Console.WriteLine(string.Format("Person ID: {0}", person.personId));
}
}
finally
{
db.Close();
}
}
}
}

The most common scenario in which this exception is thrown is when db4o fails to resolve the type of a stored object.
In your case, db4o is failing to read one of its internal objects which makes me believe you have not passed the configuration to the OpenFile() method (surely, the code you have posted is not calling ConfigureAlias() method);
Keep in mind that as of version 8.0 no further improvement will be done regarding cross platform support (you can read more details here).
