ImmIsUIMessage function

Checks for messages intended for the IME window and sends those messages to the window.

Syntax


BOOL ImmIsUIMessage(
  _In_ HWND   hWndIME,
  _In_ UINT   msg,
  _In_ WPARAM wParam,
  _In_ LPARAM lParam
);

Parameters

hWndIME [in]

Handle to a window belonging to the IME window class.

msg [in]

Message to check.

wParam [in]

Message-specific parameter.

lParam [in]

Message-specific parameter.

Return value

Returns a nonzero value if the message is processed by the IME window, or 0 otherwise.

Remarks

An application typically uses this function to display a composition string or candidate list specified by the IME. If hWndIME is NULL, the function determines if the message is a user interface message.

Windows Me/98: This function has only an ANSI version. To receive Unicode characters from a Unicode-based IME, the application should use ImmGetCompositionString.
