This Sample demonstrates how to monitor Windows clipboard changes in a WPF

application.



/////////////////////////////////////////////////////////////////////////////



In order to be notified by the system when the clipboard content changes, an

application must use the SetClipboardViewer function (user32.dll) to add its

window into the chain of clipboard viewers.



Clipboard viewer windows receive a WM_DRAWCLIPBOARD message whenever the 

content of the clipboard changes. And the WM_CHANGECBCHAIN message is sent 

to the first window in the clipboard viewer chain when a window is being 

removed from the chain.



In a WPF application, we use HwndSource class to register a Win32 window 

message handler to process the messages.



This sample also shows a workaround for a known issue in WPF 

Clipboard.GetImage() method.
