SetAlphabetHRC
2.0
Specifies which alphabet should be used in an HRC object.
int SetAlphabetHRC( HRC hrc, ALC alc, LPBYTE rgbfAlc )
Parameters
hrc
Handle to the HRC object.
alc
Alphabet. This value is one or more ALC_ values combined using the bitwise-OR
operator.
rgbfAlc
Array of bits if alc contains ALC_USEBITMAP; otherwise, it can be NULL.
Return Value
Returns HRCR_OK if successful; otherwise, returns one of the following
negative values:
Constant
| Description
| HRCR_ERROR
| Invalid parameter or other error.
| HRCR_MEMERR
| Insufficient memory.
| HRCR_UNSUPPORTED
| The recognizer does not support this function.
|
Comments
Some recognizers may not support ALC_ values and alphabet priorities. An
application should check for HRCR_UNSUPPORTED when using this function.
The following values may require Japanese, wide-character, or
recognizer-specific support: ALC_DBCS, ALC_JIS1, ALC_KANJI, ALC_OEM, ALC_HIRAGANA, and
ALC_KATAKANA. In addition, ALC_RESERVED is reserved for future use and is ignored.
Recognizers, such as the Microsoft Handwriting Recognizer (GRECO.DLL) for default
American English, can return HRCR_OK even if some of these values are set.
The size of the rgbfAlc array, if used, must be large enough to accommodate 256 bits (32 bytes). If
the nth bit is set, then the nth ANSI character is recognizable. Bits representing characters less than 32
(space) currently have no meaning.
The ALC_GESTURE value is ignored, even if it is part of the alc parameter. See EnableGestureSetHRC.
For a description of alphabets and their relationship to a recognizer, see
"Configuring the HRC" in Chapter 5, "The Recognition Process." For a list of
alphabet codes, see Chapter 13, "Pen API Constants."

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
