A common use of member functions is for encapsulation, using an accessor (commonly known as a getter) and a mutator (commonly known as a setter) instead of accessing fields directly. class Encapsulator { int encapsulated; public: int get_encapsulated() const { return encapsulated; }...

When a base class provides a set of overloaded functions, and a derived class adds another overload to the set, this hides all of the overloads provided by the base class. struct HiddenBase { void f(int) { std::cout << "int" << std::endl; } void f(bool) { std::cout &...

Member functions can also be declared virtual. In this case, if called on a pointer or reference to an instance, they will not be accessed directly; rather, they will look up the function in the virtual function table (a list of pointers-to-member-functions for virtual functions, more commonly know...

Starting a DSC on a remote machine is almost just as simple. Assuming you've already set up Powershell remoting (or enabled WSMAN). $remoteComputer = "myserver.somedomain.com" $cred = (Get-Credential) Start-DSCConfiguration -ServerName $remoteComputer -Credential $cred -Verbose Nb: A...

Sometimes it can be useful to test your Powershell data files and iterate through the nodes and servers. Powershell 5 (WMF5) added this neat little feature for doing this called Import-PowerShellDataFile . Example: $data = Import-PowerShellDataFile -path .\MydataFile.psd1 $data.AllNodes

Before you can use a resource in a configuration, you must explicitly import it. Just having it installed on your computer, will not let you use the resource implicitly. Import a resource by using Import-DscResource . Example showing how to import the PSDesiredStateConfiguration resource and the F...

Detailed instructions on getting pthreads set up or installed.

To change the execution policy for the default scope (LocalMachine), use: Set-ExecutionPolicy AllSigned To change the policy for a specific scope, use: Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy AllSigned You can suppress the prompts by adding the -Force switch.

Often you might need to execute an unsigned script that doesn't comply with the current execution policy. An easy way to do this is by bypassing the execution policy for that single process. Example: powershell.exe -ExecutionPolicy Bypass -File C:\MyUnsignedScript.ps1 Or you can use the shorthan...

Get information about the Authenticode signature from a signed script by using the Get-AuthenticodeSignature-cmdlet: Get-AuthenticodeSignature .\MyScript.ps1 | Format-List *

When signing personal scripts or when testing code signing it can be useful to create a self-signed code signing certificate. 5.0 Beginning with PowerShell 5.0 you can generate a self-signed code signing certificate by using the New-SelfSignedCertificate-cmdlet: New-SelfSignedCertificate -Friendl...

Sprite animation consists in showing an existing sequence of images or frames. First import a sequence of images to the asset folder. Either create some images from scratch or download some from the Asset Store. (This example uses this free asset.) Drag every individual image of a single animati...

Unity networking provides the High Level API (HLA) to handle network communications abstracting from low level implementations. In this example we will see how to create a Server that can communicate with one or multiple clients. The HLA allows us to easily serialize a class and send objects of ...
