Finding the handle to a WPF window

🔎 Finding the Handle to a WPF Window: The Ultimate Guide 🖥️

Are you struggling to find the handle of a WPF window? 🤔 Don't worry, we've got you covered! In this blog post, we'll address common issues and provide easy solutions to help you get the handle you need. So, let's dive in and unlock the secrets of WPF window handles! 💪

The Quest for the Handle

So, you've stumbled upon a code snippet online that suggests using the following line of code to get the handle of a WPF window:

IntPtr windowHandle = new WindowInteropHelper(Application.Current.MainWindow).Handle;

While this code might work for getting the handle of the main window, it won't serve our purpose if we're dealing with multiple windows. 😞 But fret not, there's a solution just around the corner!

Handling Multiple Windows

To access the handle of a specific WPF window, we need to make a slight modification to the code. 🛠️ Here's what you need to do:

1. First, make sure to have a reference to the window you want to obtain the handle for.

2. Next, we'll use the WindowInteropHelper class to get the job done. However, instead of using Application.Current.MainWindow, which gives us the reference to the main window, we'll replace it with our desired window reference.

// Replace "window" with your window reference
IntPtr windowHandle = new WindowInteropHelper(window).Handle;

That's it! By replacing "window" with your actual window reference, you'll be able to obtain the handle you were searching for. 🙌

Examples for Clarity

Let's put theory into practice with a couple of examples:

Example 1: Obtaining the handle of a specific Window

MainWindow mainWindow = new MainWindow();
mainWindow.ShowDialog();

// Get the handle for the "mainWindow"
IntPtr mainWindowHandle = new WindowInteropHelper(mainWindow).Handle;

Example 2: Obtaining the handle of a child Window

MainWindow mainWindow = new MainWindow();
mainWindow.ShowDialog();

ChildWindow childWindow = new ChildWindow(mainWindow);
childWindow.ShowDialog();

// Get the handle for the "childWindow"
IntPtr childWindowHandle = new WindowInteropHelper(childWindow).Handle;
