afx_msg void OnChangeCbChain( HWND hWndRemove, HWND hWndAfter );
hWndRemove
Specifies the window handle that is being removed from the Clipboard-viewer chain.
hWndAfter
Specifies the window handle that follows the window being removed from the Clipboard-viewer chain.
Called for each window in the Clipboard-viewer chain to notify it that a window is being removed from the chain.
Each CWnd object that receives an OnChangeCbChain call should use the SendMessage Windows function to send the WM_CHANGECBCHAIN message to the next window in the Clipboard-viewer chain (the handle returned by SetClipboardViewer). If hWndRemove is the next window in the chain, the window specified by hWndAfter becomes the next window, and Clipboard messages are passed on to it.
This message-handler member function calls the Default member function. Override this member function in your derived class to handle the WM_CHANGECBCHAIN message.
