Parsing PDF files in C++ can be a complex task due to the intricacies of the PDF format. However, you can use third-party libraries to simplify the process. One popular library for PDF parsing in C++ is "Poppler."

Here are the basic steps to parse PDF files using the Poppler library:

1. Install Poppler:

   • On Linux: You can typically install Poppler using the package manager for your distribution (e.g., apt-get install poppler-utils on Ubuntu).
   • On Windows: You can download the Poppler binaries from the official Poppler release page or use package managers like MSYS2 or vcpkg.

2. Use Poppler in C++:

   • Here's a simple example using Poppler in C++ to extract text from a PDF file:

#include 
#include 

int main() {
    // Replace "your_file.pdf" with the path to your PDF file
    QString pdfFilePath = "your_file.pdf";

    // Open the PDF file
    Poppler::Document* document = Poppler::Document::load(pdfFilePath);

    if (document) {
        // Iterate through pages
        for (int i = 0; i < document->numPages(); ++i) {
            Poppler::Page* pdfPage = document->page(i);

            // Extract text from the page
            QString text = pdfPage->text();
            std::cout << text.toStdString() << std::endl;

            delete pdfPage;
        }

        delete document;
    } else {
        std::cerr << "Failed to open the PDF file." << std::endl;
    }

    return 0;
}

Build and Link:

• Make sure to link your C++ program with the Poppler library. For example, using g++ on Linux:

g++ your_program.cpp -o your_program -lpoppler-qt5

4. Run the Program:

   • Execute your compiled program and provide the path to the PDF file as a command-line argument.

Keep in mind that this is a simple example, and Poppler provides more functionalities for extracting various information from PDF files. You might need to adapt the code based on your specific requirements.

To use Selenium in an Android Studio project, you can follow these steps

1. Create a New Android Studio Project

Open Android Studio and create a new Android project or open an existing project where you want to use Selenium.

2. Add Dependencies

Open your app's build.gradle file.

Add the Selenium dependency to the dependencies section. You can find the latest version on the Maven Repository.

dependencies {
    // Other dependencies...

    implementation 'org.seleniumhq.selenium:selenium-java:3.141.59'  // Use the latest version
}

Click "Sync Now" in the bar that appears at the top of Android Studio to sync the project and download the Selenium library.

3. Use Selenium in Your Code

You can now use Selenium in your Java code. For example, you can create a WebDriver instance and interact with a web page.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class MainActivity {
    public static void main(String[] args) {
        // Set the path to the ChromeDriver executable
        System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");

        // Create a ChromeDriver instance
        WebDriver driver = new ChromeDriver();

        // Example: Open Google and print the title
        driver.get("https://www.google.com");
        System.out.println("Title: " + driver.getTitle());

        // Close the browser window
        driver.quit();
    }
}

Make sure to replace "/path/to/chromedriver" with the actual path to the ChromeDriver executable. You can download ChromeDriver from the official site.

4. Configure WebDriver

Depending on the WebDriver you are using (e.g., ChromeDriver, GeckoDriver for Firefox), you may need to configure the path to the WebDriver executable. Set the system property before creating the WebDriver instance.

5. Handling WebDriver in Android

Note that running Selenium directly on Android devices is not straightforward due to differences in the architecture and limitations. If you need to automate interactions with Android apps, you might want to look into tools like Appium, which is designed specifically for mobile app automation.

Remember that Selenium is primarily designed for web automation, and using it for Android app automation may not be the best choice. For native Android app automation, consider tools like Appium or Espresso. If you are working with web views within Android apps, you can still use Selenium for those parts.

In WCF (Windows Communication Foundation), UDP communication is not supported directly as it is a point-to-point communication protocol. However, you can create a custom UDP duplex binding and use callbacks to send and receive data. Here's an example of how to do this:

1. Create a new WCF project or add a new service to an existing project.

2. Define the service contract for the UDP communication. For example:

[ServiceContract]
public interface IUdpService
{
    [OperationContract]
    void SendData(string data);

    [OperationContract]
    string ReceiveData();
}

3. Implement the service contract in a class:

public class UdpService : IUdpService
{
    private const int Port = 12345;
    private readonly UdpClient _udpClient = new UdpClient(Port);

    public void SendData(string data)
    {
        var bytes = Encoding.ASCII.GetBytes(data);
        _udpClient.Send(bytes, bytes.Length);
    }

    public string ReceiveData()
    {
        var bytes = _udpClient.Receive(ref EndPoint);
        var data = Encoding.ASCII.GetString(bytes);
        return data;
    }
}

4. Create a custom UDP duplex binding. Add the following code to a new class:

public class UdpDuplexBinding : Binding, IDisposable
{
    private UdpClient _udpClient;

    public UdpDuplexBinding()
    {
        _udpClient = new UdpClient();
    }

    public override void Close()
    {
        _udpClient?.Close();
    }

    public override void Dispose()
    {
        Close();
        GC.SuppressFinalize(this);
    }

    // Implement other required binding members
}

5. Implement a custom UdpDuplexSessionChannel for the UDP duplex binding. Add the following code to a new class:

public class UdpDuplexSessionChannel : DuplexSessionChannel
{
    private readonly UdpClient _udpClient;

    public UdpDuplexSessionChannel(UdpClient udpClient)
    {
        _udpClient = udpClient;
    }

    protected override void OnOpen(TimeSpan timeout)
    {
        base.OnOpen(timeout);
        _udpClient.EnableBroadcast = true;
    }

    protected override void OnClose()
    {
        _udpClient.Close();
        base.OnClose();
    }

    // Implement other required session channel members
}

6. Create a custom UdpDuplexSession for the UDP duplex binding. Add the following code to a new class:

public class UdpDuplex

The easiest option is to use ready-made online proxy checkers. For example, Hidemy.name, which shows the type of protocol used. Or you can simply run Speedtest - this will show you the bandwidth and response speed (ping).
