BOOL CallChain( DWORD dwChainID, HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam, LRESULT& lResult );
Return Value
TRUE if the message is fully processed; otherwise, FALSE.
Parameters
dwChainID
[in] The unique identifier associated with the chained object and its message map.
hWnd
[in] The handle to the window receiving the message.
uMsg
[in] The message sent to the window.
wParam
[in] Additional message-specific information.
lParam

Remarks
Directs the Windows message to another object’s message map. In order for the window procedure to invoke CallChain, you must specify the CHAIN_MSG_MAP_DYNAMIC macro in your message map. For an example, see the CDynamicChain overview.
CallChain requires a previous call to SetChainEntry to associate the dwChainID value with an object and its message map.
