ImmGetGuideLine

[Now Supported on Windows NT]

The ImmGetGuideLine function gets information about errors. Applications use the information to notify users.

DWORD ImmGetGuideLine(dwBufLen

HIMC hIMC,
DWORD dwIndex,
LPTSTR lpBuf,
DWORD dwBufLen
);

Parameters

hIMC

Handle to the input context.

dwIndex

Type of guideline information to retrieve. Can be one of the following values:

Value	Meaning
GGL_LEVEL	Returns the error level.
GGL_INDEX	Returns the error index.
GGL_STRING	Retrieves the error message string.
GGL_PRIVATE	Returns information about reverse conversion.

lpBuf

Pointer to the buffer that receives the error message string. This parameter can be NULL if dwIndex is not GGL_STRING or GGL_PRIVATE if dwBufLen is zero.

dwBufLen

Size, in bytes, of the buffer pointed to by lpBuf. If zero, the function returns the buffer size needed to receive the error message string, not including the terminating null character.

Return Values

The return value is an error level, an error index, or the size of an error message string, depending on the value of the dwIndex parameter. If dwIndex is GGL_LEVEL, the return value is one of the following:

Value	Meaning
GL_LEVEL_ERROR	Error. The IME may not be able to continue.
GL_LEVEL_FATAL	Fatal error. The IME cannot continue, and data may be lost.
GL_LEVEL_INFORMATION	No error, but information is available for the user.
GL_LEVEL_NOGUIDELINE	No error. Remove previous error message if still visible.
GL_LEVEL_WARNING	Unexpected input or other result. The user should be warned, but the IME can continue.

If dwIndex is GGL_INDEX, the return value is one of the following:

Value	Meaning
GL_ID_CANNOTSAVE	The dictionary or the statistics data cannot be saved.
GL_ID_NOCONVERT	The IME cannot convert any more.
GL_ID_NODICTIONARY	The IME cannot find the dictionary, or the dictionary has an unexpected format.
GL_ID_NOMODULE	The IME can not find the module that IME needs.
GL_ID_READINGCONFLICT	For example, some vowels cannot put together.
GL_ID_TOOMANYSTROKE	There are too many strokes for one character or one clause.
GL_ID_TYPINGERROR	Typing error. The IME can not handle this typing.
GL_ID_UNKNOWN	Unknown error. The application should refer to the error message string.
GL_ID_INPUTREADING	IME accepts reading character input.
GL_ID_INPUTRADICAL	IME accepts radical character input.
GL_ID_INPUTCODE	IME accepts character code input.
GL_ID_CHOOSECANDIDATE	IME accepts candidate string selection.
GL_ID_REVERSECONVERSION	Information about reverse conversion is available.

If dwIndex is GGL_STRING, the return value is the number of bytes of the string copied to the buffer, or if dwBufLen is zero, the return value is the buffer size needed to receive the string.

If dwIndex is GGL_PRIVATE, the return value is the number of bytes of information copied to the buffer. If dwIndex is GGL_PRIVATE and dwBufLen is zero, the return value is the buffer size needed to receive the information.

Remarks

Applications typically call this function after receiving an IMN_GUIDELINE message.
