I'm Using WIA Layer Sample in my machine for a educational purpose. But it gives me following Error In Visual Basic 2008. Error Shown on this code

VB

Picture1.BackgroundImage = img.ARGBData.Picture(w, h)

Error Is this

Unable to cast COM object of type 'System.__ComObject' to class type 'System.Drawing.Image'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.

You obviously have an error in the img.ARGBData.Picture(w, h) call. Are you sure it returns a System.Drawing.Image? If not, perhaps you need to figure out what this method returns and then figure out how to cast this return value to a System.Drawing.Image.
Without any more information in your question, you won't get a much better answer.
