The WM_CHANGECBCHAIN message is sent to the first window in the clipboard viewer chain when a window is being removed from the chain.
A window receives this message through its WindowProc function.
Syntax
WM_CHANGECBCHAIN
WPARAM wParam
LPARAM lParam;
Parameters
- wParam
-
Handle to the window being removed from the clipboard viewer chain.
- lParam
-
Handle to the next window in the chain following the window being removed. This parameter is NULL if the window being removed is the last window in the chain.
Return Value
If an application processes this message, it should return zero.
Remarks
Each clipboard viewer window saves the handle to the next window in the clipboard viewer chain. Initially, this handle is the return value of the SetClipboardViewer function.
When a clipboard viewer window receives the WM_CHANGECBCHAIN message, it should call the SendMessage function to pass the message to the next window in the chain, unless the next window is the window being removed. In this case, the clipboard viewer should save the handle specified by the
lParam parameter as the next window in the chain.
