ImmIsUIMessageA function (imm.h)
Checks for messages intended for the IME window and sends those messages to the window.
Syntax
BOOL ImmIsUIMessageA(
HWND unnamedParam1,
UINT unnamedParam2,
WPARAM unnamedParam3,
LPARAM unnamedParam4
);
Parameters
unnamedParam1
unnamedParam2
unnamedParam3
unnamedParam4
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.
Note
The imm.h header defines ImmIsUIMessage as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
