The ImmIsUIMessage function checks for messages intended for the IME window and sends those messages to the specified window.
BOOL ImmIsUIMessage(
HWND hWndIME, | |
UINT msg, | |
WPARAM wParam, | |
LPARAM lParam | |
); |
If the message is processed by the IME window, the return value is a nonzero value.
If the message is not processed by the IME window, the return value is zero.
An application typically uses this function to display any composition string or candidate list specified by IME. If hWndIME is NULL, the function checks whether the message is a user interface message.
