Question

I am integrating a webcam in a WPF application. I can see the camera feed in the main window, as I pass its HANDLE on to the DirectShow functions. But this is not what I want.

The main form has a Image control, where I’d like to see the output. However, in order to do this, I need the control’s Handle.

Any hint on how to do this?

Thanks in advance,
Gianluca.

An Image Control in WPF, unlike Windows Forms, doesn’t actually have an HWND.

WPF works differently than Windows Forms – each control is not a wrapper around a native “window” with a handle, but rather composed together using Direct3D at runtime by the layout system.

If you need to actually host output from a Webcam inside of a WPF window, you should look at using HwndHost (or a subclass). The simplest way is often to just host a Windows Forms control inside of a WindowsFormsHost, though managing an HWND yourself via HwndHost is more efficient.
