WM_CHANGECBCHAIN

This message notifies the first window in the clipboard-viewer chain that a window is being removed from the chain.

Parameters

wParam

Contains the handle to the window that is being removed from the clipboard-viewer chain.

lParam

Contains the handle to the window that follows the window being removed from the clipboard-viewer chain, or NULL if there is none.

Comments

Each window that receives the WM_CHANGECBCHAIN message should call the SendMessage function to pass on the message to the next window in the clipboard-viewer chain. If the window being removed is the next window in the chain, the window specified by lParam parameter becomes the next window, and clipboard messages are passed on to it.
