GetSymbolsHRCRESULT
- 0
Retrieves an array of symbol values corresponding to a recognition result. A
recognizer must export this function.
int GetSymbolsHRCRESULT( HRCRESULT hrcresult, UINT iSyv, LPSYV rgsyv, UINT cSyv )
Parameters
hrcresult
Handle of a results object.
iSyv
Index of the first symbol of interest in the results object.
rgsyv
Address of a buffer in which to put the symbols. The array must be large
enough to store cSyv symbols.
cSyv
The size of rgsyv in symbols (not bytes). This is the number of symbols to be returned. A value
of 0 is legal, in which case the function simply returns 0.
Return Value
Returns the count of symbols copied, if successful; otherwise, returns one of
the following negative values:
Constant
| Description
| HRCR_ERROR
| Invalid parameter or other error.
| HRCR_MEMERR
| Insufficient memory.
|
Comments
It is possible to allocate a small buffer in rgsyv and call this function repeatedly, incrementing the index iSyv each time by the number of symbols returned in the previous call, until the
function returns 0.
Example
The following example gets a character result, using a small buffer:
#define CBCHBUF 1024 // Char buffer
#define CSYVMAX 32 // Relatively small symbol chunk
HRC vhrc; // Handle to a handwriting context
HRCRESULT vhrcresult; // Handle to a recognition result
SYV vrgsyv[CSYVMAX]; // Symbol result buffer
char vrgcBuff[CBCHBUF]; // Buffer for recognition results
.
. // Code that creates HRC, gets input, etc....
.
EndPenInputHRC( vhrc ); // Tell recognizer no more ink
ProcessHRC( vhrc, PH_MAX ); // Finish recognition
.
. // Retrieve a handle to the results
.
if (GetResultsHRC( vhrc, &vhrcresult, 1 ) > 0)
{
int i = 0, cSyv;
// Retrieve some symbols
while ((cSyv = GetSymbolsHRCRESULT( vhrcresult,
i, vrgsyv, CSYVMAX )) > 0)
{
if (i + cSyv + 1 > CBCHBUF) // Don't overflow buffer
cSyv = CBCHBUF - i - 1;
if (cSyv > 0) // Still have something?
{
SymbolToCharacter( vrgsyv, cSyv, vrgcBuff + i, NULL );
i += cSyv;
}
if (i + 1 >= CBCHBUF)
break;
}
- rgcBuff[i] = chNull; // Terminate string
}
DestroyHRCRESULT( vhrcresult ); // We're finished with result
DestroyHRC( vhrc ); // Finished with this HRC session

.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 » |
