Extracting picture from picturebox with handleref

Question

I am using Microsoft Expression Encoder to capture images from the webcam..

Presumably, this code is used to assign the image to the picturebox (panelVideoPreview):

_deviceSource.PreviewWindow = new PreviewWindow(new HandleRef(panelVideoPreview,panelVideoPreview.Handle));

This all works fine, but as soon as I try this:

panelVideoPreview.Image.Save("C:\\Temp\\Temp3.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

It says that the Image property is null. How can I get around this?

Any possible suggestions are appreciated!

Answer 1

I think the Problem is HandleRef isn't finished... Have you tried to Await the Object?
