Question

I want to display live image from the usb PC webcam using C# windows application in Visual Studio 2010. I have searched about that and find the link http://channel9.msdn.com/coding4fun/articles/Look-at-me-Windows-Image-Acquisition but when i tried this code

           WIA.CommonDialog class1 = new WIA.CommonDialog();
            Device d = class1.ShowSelectDevice(WiaDeviceType.UnspecifiedDeviceType, true, false);
            if (d != null)
            {
                settings.DeviceID = d.DeviceID;
                settings.Save();
            }

I am getting the giving compilation error

error CS0103: The name 'settings' does not exist in the current context

And I am not able to find out the solution for this error.
Can anybody body please tell me what would be the solution for this error?
And Is there any other best method to display live images from usb webcam?

Any help would be appreciated….

Thanks in Advance..

It looks as though you haven’t defined a settings object, however it doesn’t seem to be in the tutorial either. Personally though I would use AForge.NET library as this provides an extremely easy interface to webcams.
