ImeProcessKey

BOOL ImeProcessKey (HIMC hIMC, UINT uVirKey, DWORD lParam, 
    CONST LPBYTE lpbKeyState)

Preprocesses keystrokes given through IMM.

• Returns TRUE if a key is necessary for the IME with the given input context, FALSE otherwise.

hIMC

Handle of the input context.

uVirKey

Virtual key to be processed.

lParam

lParam of a key message.

lpbKeyState

Address of a 256-byte array that contains the current keyboard state. The IME should not modify the keyboard state.

The system determines a key is handled by IME by calling this function. When the function returns TRUE, the IME processes the key message before it is passed to an application. The system also calls the ImeToAsciiEx function. The function returns FALSE if the IME does not handle the key, in which case the system sends the key message to the target application.
