I'm looking to create a C# application that changes content according to which application currently has focus. So if the user is using Firefox, my app would know that. Same for Chrome, Visual Studio, TweetDeck etc.
Is this possible, and if so - how would I go about achieving it?
I have a feeling I'm asking for to much - but it's worth a try.
Many thanks in advance.

C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of UNIX-based operating systems are written in C.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
This can be done in pure .NET using the Automation framework that is part of the WPF. Add references to UIAutomationClient
and UIAutomationTypes
and use Automation.AddAutomationFocusChangedEventHandler
, e.g.:
public class FocusMonitor
{
public FocusMonitor()
{
AutomationFocusChangedEventHandler focusHandler = OnFocusChanged;
Automation.AddAutomationFocusChangedEventHandler(focusHandler);
}
private void OnFocusChanged(object sender, AutomationFocusChangedEventArgs e)
{
AutomationElement focusedElement = sender as AutomationElement;
if (focusedElement != null)
{
int processId = focusedElement.Current.ProcessId;
using (Process process = Process.GetProcessById(processId))
{
Debug.WriteLine(process.ProcessName);
}
}
}
}
