Changing Windows Service Start parameters

You have created or installed service that uses Start parameters and now want to change them you would expect to be able to change them in Services (services.msc), but unfortunately changes made to „Start parameters“ cannot be applied from that application. But there are few approaches that can help you quickly to fix this issue. In following examples we will be changing Solr 6.6.2 service that was installed by using NSSM (the Non-Sucking Service Manager)

NSSM

If you have just installed your service you can try removing service and adding it again with correct parameters using Command prompt by running following commands (without brackets):

nssm remove {ServiceName}

nssm install {ServiceName} {ServiceLocation} {ServiceParameters}

If removing and adding service is not an option for you there is also an NSSM „set“ command designed for updating your Services by typing:

nssm set solr662new “AppParameters” “start -f -p 8984”

Registry

Another approach would be using Registry. All services from services.msc are being read from one Registry location: „Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\{Service Name}“, and if your service has sub key/folder „Parameters“, expand it and there you can find AppParameters, where you can visually change your „Start parameters“

In following code we are accessing Registry key „Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services“ and looking for service named „solr662new“, after it is found we are updating DisplayName and AppParameters values. If you need to update values other than AppParameters try checking out ServiceRegistryDtoModel and ParametersDtoModel models and UpdateRegistryKey method and update it to suit your needs.

Sitecore Commerce XC 9.2 installation: RebuildIndexes_RebuildIndex-Core : WebRequest Request failed: The operation has timed out

01/11/2019 / Darko / 0 Comments

Congrats on almost finishing Sitecore XC 9.2 installation. Only few installation steps before it is finished, but this error keeps pooping up.

Screenshot of RebuildIndexes_RebuildIndex-Core error

Json file Common.RebuildIndexes.json that is located in SIF->Configuration->Commerce->Comon, has a few RequestTimeout properties that define how long will install script wait before trying to start step again. Importunately if you have slow PC or Virtual Machine, default values are not giving your PC enough time to finish rebuilding indexes. By increasing these values, your PC will have time to complete this steps and installation will finish successfully.

My example of Common.RebuildIndexes.json

Successful installation after increasing timeouts

How to open Console Window in another screen

14/10/2019 / Darko / 0 Comments

At some point in time you got frustrated that Windows console app opens on monitor that is not ideal for you or you just want to move it to another screen. Unfortunately Console does not offer out of the box solution to fix this problem so we need to find solution out of the box.

My solution is based upon consuming Windows API’s and Windows Forms to easily create maintainable solution.

SetWindowPos function seems to be a good start. By using it we can set Windows starting X and Y axis, as well as its width, height and window position. To use this function there are 2 challenges:

Getting monitors starting X point and getting the console Windows handle.

Monitors X axis point can be easily acquired by using WinForms System.Windows.Forms.Screen.AllScreens property, which stores all connected monitors ant their information.

Getting Console Window handle is a bit trickier. First we need to use GetConsoleWindow function assign it to the pointer and then pass it to the SetWindowPos.

SetWindowPos has a limitation thou. If we want to maximize screen, we cannot do it (we can extend it to monitors max width and height but its state would still not be maximized). Here we can use ShowWindow function where we pass our Console window and it’s desired state.

That would be all for this short tutorial, code sample is bellow.

Happy coding!

So next thing I tried is to remove both Web deploy packages.

Unfortunately that did not work 🙁

So i went to the Microsoft site:

https://www.microsoft.com/en-us/download/details.aspx?id=43717

and downloaded x64 version of WebDeploy 3.6 and installed it

That did not help either

Parameterizing Unit Tests using xUnit

05/07/2017 / Darko / 0 Comments

xUnit allows our unit test to use parameters, which allows us to test our code for multiple scenarios without needing to write multiple methods with same content.

Let’s look at example from previous lesson

[Fact]
public void ShouldReturnSumOfValues()
   {
	Program prog = new Program();
	int addingResult = prog.Add(3, 9);

	Xunit.Assert.Equal(12, addingResult);
   }

[Fact]

public void ShouldReturnSumOfValues()

{

Program prog = new Program();

int addingResult = prog.Add(3, 9);

Xunit.Assert.Equal(12, addingResult);

}

Here we test if 3 + 9 equals 12.

But what if we wanted to test our Add method for multiple scenarios?

We could use InlineData Attribute.

InlineData Attribute allows us to run our test with input parameters, and passes those parameters to test method using params object[] data.

[Fact]
[InlineData(15,5,10)][InlineData(15,5,10)]
[InlineData(55, 4, 51)]
[InlineData(99, 33, 66)]
public void ShouldReturnSumOfValues(int result, 
	int valueOne, int valueTwo)
{
	Program prog = new Program();
	int addingResult = prog.Add(valueOne, valueTwo);

	Xunit.Assert.Equal(result, addingResult);
}

[Fact]

[InlineData(15,5,10)][InlineData(15,5,10)]

[InlineData(55, 4, 51)]

[InlineData(99, 33, 66)]

public void ShouldReturnSumOfValues(int result,

int valueOne, int valueTwo)

{

Program prog = new Program();

int addingResult = prog.Add(valueOne, valueTwo);

Xunit.Assert.Equal(result, addingResult);

}

We are not done yet.

Compiler is not happy and we are getting error : Fact methods cannot have parameters.

Simple solution is to replace Fact Attribute with Theory Attribute

[Theory]
[InlineData(15,5,10)][InlineData(15,5,10)]
[InlineData(55, 4, 51)]
[InlineData(99, 33, 66)]
public void ShouldReturnSumOfValues(int result, 
	int valueOne, int valueTwo)
{
	Program prog = new Program();
	int addingResult = prog.Add(valueOne, valueTwo);

	Xunit.Assert.Equal(result, addingResult);
}

[Theory]

[InlineData(15,5,10)][InlineData(15,5,10)]

[InlineData(55, 4, 51)]

[InlineData(99, 33, 66)]

public void ShouldReturnSumOfValues(int result,

int valueOne, int valueTwo)

{

Program prog = new Program();

int addingResult = prog.Add(valueOne, valueTwo);

Xunit.Assert.Equal(result, addingResult);

}

Now, when we run our unit test we can see that same test method ran 3 times an all test have passed 🙂

Also note that we can also see input parameters!

Beginners guide to xUnit

04/07/2017 / Darko / 0 Comments

To add xUnit to your project open up NuGet package manager

(Tools -> NuGet Package manager -> Manage Nuget packages for Solution

Right-click References of your project and chose Manage Nuget packages)

xUnit Nuget installation

And find xUnit package by James Newkirk and Brad Wilson and press install.

To use xUnit in your project you do not have to decorate your class with TestClass attribute!

You must only decorate your methods with Fact Attribute.

Also be sure to reference Xunit assembly in your class file because xUnit’s Assert class is from that namespace.

If tests you write do not show in Test explorer, open NuGet packet manager and add xunit.runner.visualstudio package (do not be confused if you see Visual Studio 2012+ in description, it is just saying that this is for version from VS 2012 an onwards).

There is also neat trick to modify name of your tests. By default Test explorer is showing xUnit’s test names in format Class.Method, but you can only display test Method names. Add new json file to root of project and name it “xunit.runner.json” and open properties of that file and under “Copy to Output Directory” option chose “Copy if newer”.

Open under xunit.runner.json file and under Schema input “https://xunit.github.io/schema/v2.2/xunit.runner.schema.json”, then inside brackets type “methodDisplay”: “method”.

Happy unit testing 🙂

How to create Unit Test with VisualStudio 2017

04/07/2017 / Darko / 0 Comments

This brief tutorial will show you how to create Unit Test with VisualStudio 2017.

There are a few ways to create unit test using VS 2017.

1) Create unit test From the class

Create new Console Application

And in a Program class add public method.

Right click on a method and chose “Create Unit Tests”.

How to add an Unit test project from a class.

Be sure to add a public method because without it you will get an error:

Create Unit Tests is supported only within a public class or a public method

An error is pretty straight forward 🙂

Error you get when adding Unit test project from an empty class or class that has only static members.

Then you can chose additional options or additional Testing frameworks

Unit test options

2) Manually adding a test project

Create new method that returns string with value test.

public string TestResult()
    {
        return "test";
    }

public string TestResult()

{

return "test";

}

Right click solution and add Unit Testing project

Choosing unit test project

Then add an reference to project you wish to unit test

And create a new class ProgramTests

Decorate class with a [TestClass] Attribute

Also add a ShouldReturnTestString void method decorated with a [TestMethod] Attribute

using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace UnitTestingExample.UT
{
    [TestClass]
    public class ProgramTests
    {
        [TestMethod]
        public void ShouldReturnTestString()
        {
            //Arange
            Program prog = new Program();

            //Act
            string result = prog.TestResult();

            //Assert
            Assert.AreNotSame("test", result);
        }
    }
}

using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace UnitTestingExample.UT

{

[TestClass]

public class ProgramTests

{

[TestMethod]

public void ShouldReturnTestString()

{

//Arange

Program prog = new Program();

//Act

string result = prog.TestResult();

//Assert

Assert.AreNotSame("test", result);

}

Be sure to add those Attributes because without them you will not be able to run unit test. Give it a shot.

DataContractSerializer

27/09/2016 / Darko / 0 Comments

DataContractSerializer made its first appearance with release of WCF but can operate outside WCF.

DataContractSerializer can serialize types decorated with DataContract, MessageContract, Serializable attributes, types that implement IXmlSerialisable and all public types without Attributes.

During serialization Reference integrity is by default not preserved. You can preserve it by setting “IsReference = true” to DataContract attribute. Note that this approach my cause problems if DataContractSerializer is not serializer who will deserialize data.

[DataContract(IsReference = true)]

1	[DataContract(IsReference = true)]

You can also use OnSerializing, OnSerialized, OnDeserializing, OnDeserialized Attributes to fine-grain your serialization process.

This tutorial will explain how to serialize and deserialize types by decorating type with DataContract attribute.

First we use need to add reference to System.Runtime.Serialization. Secondly we decorate the type with DataContract Attribute, and inside type wee decorate fields and properties with DataMember Attribute. Then we instantiate DataContractSerializer instance and use its WriteObject and ReadObject methods to serialize/deserialize data.

Example of DataContractSerializer:

using System;
using System.Runtime.Serialization;
using System.IO;
using System.Xml.Linq;

namespace DataContractSerializerExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Choose between types to serialize
            Employee employee = new Employee()
            {
                _employeeId = 1,
                employeeName = "JohnDoe",
                _employeeDepartment = new Department()
                {
                    _departmentId = 1,
                    _departmentName = "Sales"
                }
            };

            
            ClubActivity activity = new ClubActivity()
            {
                _employeeId = 1,
                employeeName = "JohnDoe",
                ActivityName = "Gym",
                _employeeDepartment = new Department()
                {
                    _departmentId = 1,
                    _departmentName = "Sales"
                }
            };

            // We will be reading data from the memory

            MemoryStream memoryStream = new MemoryStream();

            // both ClubActivity and Employee classes are provided
            // as parameters so you can experiment 
            // in SerializeData Method
            Stream stream = SerializeData(employee, activity, memoryStream);
            
            DisplaySerializationResultInConsole(stream);
            //stream.Position = 0;

            //And now lets deserialize data
            Deserialize(stream);

            Console.ReadKey();
        }

        private static Stream SerializeData(Employee employee, ClubActivity activity, MemoryStream memoryStream)
        {
            // Note that we needed to supply Type information to constructor
            // Reason is that type and Assembly information are not serialized 
            DataContractSerializer dataContractSerializer = new DataContractSerializer(typeof(Employee));

            // WriteObject method is responsible for serialization itself
            dataContractSerializer.WriteObject(memoryStream, activity);

            // It is best to rewind stream to 0 position now
            // so consumer of of stream can consume it right away.
            memoryStream.Position = 0;

            return memoryStream;
        }

        private static void Deserialize(Stream stream)
        {

            // ReadObject method is responsible for Deserialization
            object employeeObject = dataContractSerializer.ReadObject(stream);

            // As you can see Club activity object has been deserialized
            ClubActivity oldEmployee = employeeObject as ClubActivity;

By using DataMember Attribute we can serialize automatic properties, because property itself will be serialized and not its backing field.

Because DataContractSerializer does not store type and assembly information we need to tell it which is the type we wish to serialize by specifying type in the DataContractSerializer constructor.

As no type or assembly information are preserved be sure to supply KnownType Attribute to your base class to be able to use inheritance properly.

Binary serialization

26/09/2016 / Darko / 0 Comments

Today’s topic is Binary serialization, if you wish to read more about serialization or other types of serialization please visit this link:

Binary serialization is type of serialization where type fidelity and reference integrity are preserved, meaning assembly information, private and public fields are being preserved as well as theirs memory locations. You would normally use binary serialization to preserve application state, store it to a backing store (storage medium) and use it later to run application on same computer or maybe multiple other computers.

Hearth of binary serialization is BinaryFormatter class and its Serialize and Deserialize methods. Serialize and Deserialize methods take two parameters stream and object graph and serialize or deserialize object accordingly. Result of serialization are unreadable to human eye but you can read some information:

BinaryFormatter serialization result

As you can see type and field information are preserved.

If you wish serialized data in more readable way you can use SoapFormatter. Note that SoapFormatter is obsolete so use it only for debugging and testing purposes.

To mark a type serializable use Serializable attribute to decorate type. Serializable attribute is not inherited so if you wish to serialize both base and derived class decorate both of them with serializable attribute. Other approach would be to implement ISerializable interface.

If you wish not to serialize filed add NonSerialized attribute.

You can serialize null types, but you can not serialize or deserialize null streams.

Properties are not serialized but their private fields are. Do not serialize auto implemented properties because you cannot guarantee that theirs private fields will have the same name on the other machines as they do on yours.

If we wish more control during Serialization/Deserialization processes we can use attributes from System.Runtime.Serialization and apply them to the methods.
Attributes we can use for methods during serialization:
OnSerializingAttribute – use this attribute to prepare data before deserializing . For example encrypt password field or change distance from miles to kilometers.
OnSerializedAttribute – restores type to a status it was before applying OnSerializingAttribute.

Attributes we can use for methods during serialization:
OnDeserializingAttribute – because serialization cannot use constructor, use this attribute for method that will simulate constructor, and maybe set fields to default values.
OnDeserializedAttribute – use this attribute to manually set value of the fields just after serialization process has finished.

Example for Binary serialization.

We will try to serialize data from Employee class:

using System;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using System.Runtime.Serialization.Formatters.Soap;

namespace BinarySerialization
{
    class Program
    {
        static void Main(string[] args)
        {
            // Data we wish to serialize
            Employee employee = new Employee()
            {
                _employeeId = 1,
                _employeeName = "JohnDoe",
                _employeeDepartment = new Department()
                {
                    _departmentId = 1,
                    _departmentName = "Sales"
                }
            };

            // We will be reading data from the memory
            // so it is best to use Memory stream.
            MemoryStream memoryStream = new MemoryStream();

            //Lets start by Serializing data.
            Stream stream = SerializeData(employee, memoryStream);

            //Console.WriteLine(new StreamReader(memoryStream).ReadToEnd());
            DisplaySerializationResultInConsole(stream);
            //stream.Position = 0;

            //And now lets deserialize data
            Deserialize(stream);

            Console.ReadKey();
        }

        private static Stream SerializeData(Employee employee, MemoryStream memoryStream)
        {
            // To view result in more readable way change
            // BinaryFormatter type to SoapFormatter

            //// Lets  start by instatiating BinaryFormatter
            BinaryFormatter binaryFormatter = new BinaryFormatter();

            // And let BinaryFormatter.Serialize method do its job
            binaryFormatter.Serialize(memoryStream, employee);

            // It is best to rewind stream to 0 position now
            // so consumer of of stream can consume it right away.
            memoryStream.Position = 0;

            //// Uncomment bottom line 
            //// to see the result of serialization
            //DisplaySerializationResultInConsole(memoryStream);

            // Stream is ready to be transmitted
            // So lets send it.
            return memoryStream;
        }
        
        private static void Deserialize(Stream stream)
        {
            // If you have serialized data by using SoapFormatter
            // change type of binaryFormatter variable to SoapFormatter

            // Lets start Deserialization process by instantiating BinaryFormatter
            BinaryFormatter binaryFormatter = new BinaryFormatter();

            // BinaryFormatter.Deserialize return object type
            object employeeObject = binaryFormatter.Deserialize(stream);

            // As you can see Employee object has been deserialized
            Employee oldEmployee = employeeObject as Employee;

            // Proof of Deserialization result:
            Console.WriteLine("Deserialization result: Employee id:{0}, Employee name: {1}, Department id: {2}, Department name: {3}", oldEmployee._employeeId, oldEmployee._employeeName, oldEmployee._employeeDepartment._departmentId, oldEmployee._employeeDepartment._departmentName);

        }

        private static void DisplaySerializationResultInConsole(Stream stream)
        {
            Console.WriteLine(new StreamReader(stream).ReadToEnd());
            stream.Position = 0;
        }
    }

    [Serializable]
    public class Employee
    {
        public int _employeeId;
        public string _employeeName;
        public Department _employeeDepartment;

    [Serializable]
