How to Use Google cloud Datastore with C# - c#

I am new to google cloud datastore and trying to access 'KIND' and save to with C#. I have searched the documentation available on google cloud but did not find how to access data on google datastore and save to. I am able to authenticate.
There is proper documentation for JAVA, NODE.JS, GO and PYTHON but not for .NET.
Please help.

Yes, you can totally use C# to access google cloud datastore.
This sample shows you how:
https://cloud.google.com/dotnet/getting-started/using-cloud-datastore
Here's a direct link to the code:
https://github.com/GoogleCloudPlatform/getting-started-dotnet/blob/master/aspnet/2-structured-data/Models/DatastoreBookStore.cs
To search by Kind:
var query = new Query()
{
Limit = pageSize,
Kinds = new[] { new KindExpression() { Name = "Book" } },
};
To create a Key with the specified Kind:
public static Key ToKey(this long id)
{
return new Key()
{
Path = new KeyPathElement[]
{
new KeyPathElement() { Kind = "Book", Id = (id == 0 ? (long?)null : id) }
}
};
}
More documentation is coming soon.

I've wrote a mini .NET ORM for the Google Datastore:
https://github.com/NoGame/GoogleDatastoreORM
You might find it useful.

The actual API Reference is almost impossible to find. I eventually tracked it down here: https://googlecloudplatform.github.io/google-cloud-dotnet/docs/Google.Cloud.Datastore.V1/api/Google.Cloud.Datastore.V1.DatastoreDb.html#Google_Cloud_Datastore_V1_DatastoreDb_Create_System_String_System_String_Google_Cloud_Datastore_V1_DatastoreClient_
Hopefully this helps someone looking for all of the documentation.

tik4net hotspot user usage report in c#

what is the best way to get daily bytes-out and byte-in report for every user in hotspot list(without the user manager).i found the tik4net but i couldn't use it and i found almost no documentation on this reference.
i have tried the mk.cs and tik4net already but no luck so far.
this was the sample on using torch tool :
using (ITikConnection connection = ConnectionFactory.CreateConnection(TikConnectionType.Api))
{
connection.Open("IP", "USR", "PW");
var loadingContext = connection.LoadAsync<ToolTorch>(
torchItem => Console.WriteLine(torchItem.ToString()),
error => Console.WriteLine(error.ToString()),
connection.CreateParameter("interface", "DSL"),
connection.CreateParameter("port", "any"),
connection.CreateParameter("src-address", "0.0.0.0/0"),
connection.CreateParameter("dst-address", "0.0.0.0/0"));
Console.ReadLine();
loadingContext.Cancel();
{
so the question is:
what is the best reference in c# to get user reports without the user manager in c#?
can anyone please provide some sample code ?
UPDATE :
i just worked around and played with the code a little bit and got here :
using (ITikConnection connection = ConnectionFactory.CreateConnection(TikConnectionType.Api))
{
connection.Open("IP", "USR", "PW");
var hs = connection.LoadAll<HotspotActive>();
foreach (var user in hs)
{
var ids = user.Id;
listBox1.Items.Add(ids);
connection.Delete<HotspotActive>(user);
}
}
but i get an exception error on connection.Delete<HotspotActive>(user); , i dont know if i went the correct way.

CreateJob for Azure Data Lake Analytics from C#

I am trying to create a Job using the C# api and the DataLakeAnalyticsJobManagementClient and have been unsuccessful in every attempt with the error message: "Invalid job definition.". There is no other useful information about what is invalid about it. The job is a U-SQL job and I began bey creating it in the azure portal and that worked just fine and ran correctly with no errors.
I am building up the JobInformation and JobProperties using the same information that the portal test one used and I know the U-SQL statements are valid.
JobProperties props = new JobProperties(File.ReadAllText(#"C:\myusqlscript.usql"));
var myId = Guid.NewGuid();
JobInformation jobNfo = new JobInformation("mysamplejob", JobType.USql, props,myId) { DegreeOfParallelism = 1, Priority = 1000};
jobNfo.Validate(); //<--this doesn't throw an exception either
var jobs = await _adlaJobClient.Job.ListAsync("myanalyticsaccountname");
var adlaJob = await _adlaJobClient.Job.CreateAsync("myanalyticsaccountname", myId, jobNfo);
I have tried various combinations of constructors and property settings including just using defaults for some of the properties and I get the same result: "Invalid job definition." There is no other info that would indicate missing information or formatting issues or anything like that.
Anyone out there created Azure Data Lake Analytics jobs with the C# API?
Anyone out there created Azure Data Lake Analytics jobs with the C# API?
You need to use USqlJobProperties instead of JobProperties.
var props = new USqlJobProperties(File.ReadAllText(#"C:\myusqlscript.usql"));
The official document for Data Lake analytics get started .NET SDK is not available. But we can also get some useful sample code from the histories of this document.
public static Guid SubmitJobByPath(string scriptPath, string jobName)
{
var script = File.ReadAllText(scriptPath);
var jobId = Guid.NewGuid();
var properties = new USqlJobProperties(script);
var parameters = new JobInformation(jobName, JobType.USql, properties, priority: 1, degreeOfParallelism: 1, jobId: jobId);
var jobInfo = _adlaJobClient.Job.Create(_adlaAccountName, jobId, parameters);
return jobId;
}

How to get all installations when using Azure Notification Hubs installation model?

Using NotificationHubClient I can get all registered devices using GetAllRegistrationsAsync(). But if I do not use the registration model but the installation model instead, how can I get all installations? There are methods to retrieve a specific installation but none to get everything.
You're correct, as of July 2016 there's no way to get all installations for a hub. In the future, the product team is planning to add this feature to the installations model, but it will work in a different way. Instead of making it a runtime operation, you'll provide your storage connection string and you'll get a blob with everything associated with the hub.
Sorry for visiting an old thread... but in theory you could use the GetAllRegistrationsAsyc to get all the installations. I guess this will return everything without an installation id as well, but you could just ignore those if you choose.
Could look something like this
var allRegistrations = await _hub.GetAllRegistrationsAsync(0);
var continuationToken = allRegistrations.ContinuationToken;
var registrationDescriptionsList = new List<RegistrationDescription>(allRegistrations);
while (!string.IsNullOrWhiteSpace(continuationToken))
{
var otherRegistrations = await _hub.GetAllRegistrationsAsync(continuationToken, 0);
registrationDescriptionsList.AddRange(otherRegistrations);
continuationToken = otherRegistrations.ContinuationToken;
}
// Put into DeviceInstallation object
var deviceInstallationList = new List<DeviceInstallation>();
foreach (var registration in registrationDescriptionsList)
{
var deviceInstallation = new DeviceInstallation();
var tags = registration.Tags;
foreach(var tag in tags)
{
if (tag.Contains("InstallationId:"))
{
deviceInstallation.InstallationId = new Guid(tag.Substring(tag.IndexOf(":")+1));
}
}
deviceInstallation.PushHandle = registration.PnsHandle;
deviceInstallation.Tags = new List<string>(registration.Tags);
deviceInstallationList.Add(deviceInstallation);
}
I am not suggesting this to be the cleanest chunk of code written, but it does the trick for us. We only use this for debugging type purposes anyways

Examples of Quickbase API in C#

I am fairly new to the use of APIs and haven't touched Quickbase until today. I was researching the Quickbase API and it seemed as if all the examples I saw were written in XML or some similar variant. Is there a way to write code in C# that will do the same things that I saw could be done on the Quickbase website's API documentation? If you know of any code examples, please let me know.
There is a QuickBase C# SDK that might help get you started.
using System;
using Intuit.QuickBase.Client;
namespace MyProgram.QB.Interaction
{
class MyApplication
{
static void Main(string[] args)
{
var client = QuickBase.Client.QuickBase.Login("your_QB_username", "your_QB_password");
var application = client.Connect("your_app_dbid", "your_app_token");
var table = application.GetTable("your_table_dbid");
table.Query();
foreach(var record in table.Records)
{
Console.WriteLine(record["your_column_heading"]);
}
client.Logout();
}
}
}
There is also a QuickBase API Wrapper example as well.
Back in 2009 I wrote an .NET API for QuickBase which makes working with the platform easy, it also supports uploading and downloading of attached files.
IQuickBaseService svc = new QuickBaseService("user", "pass", "URL", "token");
Schema schema = svc.GetSchema("DBID");
Console.WriteLine("Schema : {0}", schema.Name);
Console.WriteLine("Variables - ");
for (KeyValuePair<string, string> ent in schema.Variables.OrderBy(en => en.Key)) {
Console.WriteLine("Var: {0} = {1}", ent.Key, ent.Value);
}
for (Query q : schema.Queries) {
// Work with queries.
}
// schema.Children
// schema.Fields
// ...
svc.SignOut();
Performing a query is simple.
QueryResult res;
res = svc.Query("tableid", 1); // Execute query number 1
res = svc.Query("tableid", "{{140.EX.'1'}}") // execute QB query text
foreach (QueryRow row in result.Rows) {
// Do something with row, use get<type>, not all shown here.
// row.GetBool(1);
// row.GetInt(1);
// row.GetLong(1);
// row.GetFloat(1);
// row.GetDouble(1);
// row.GetDecimal(1);
// row.GetString(1);
// row.GetDate(1);
// row.GetDateTime(1);
// row.GetObject(1);
}
QuickBase SDK Code is now moved to github https://github.com/QuickbaseAdmirer/QuickBase-C-Sharp-SDK

How to programatically in c# get the latest top "n" commit messages from a svn repository

I'd like to build a site which simply displays the top latest (by date, revision?) "n" commit logs plus other associated info.
What's the best way to do this? I started having a quick look at SharpSvn, but the GET seems to be based on Revision ranges rather than date.
I'd like a simple example for .Net in c# based on any available library which gets the job done.
Since you mentioned using SharpSVN, I happen to have written this in BuildMaster:
private static IList<string> GetLatestCommitMessages(Uri repository, int count)
{
using (var client = new SvnClient())
{
System.Collections.ObjectModel.Collection<SvnLogEventArgs> logEntries;
var args = new SvnLogArgs()
{
Limit = count
};
client.GetLog(repository, args, out logEntries);
return logEntries.Select(log => log.LogMessage).ToList();
}
}
