ISpRecoGrammar::LoadCmdFromProprietaryGrammar (Windows CE 5.0)

Artigo
09/14/2012

This method loads a proprietary grammar. Applications should use LoadCmdFromProprietaryGrammar when using a proprietary grammar format that the SR engine supports (see ISpSREngine::LoadProprietaryGrammar). If the current SR engine does not support the proprietary grammar format (specified using rguidParam and pszStringParam), then the SR engine can return E_NOTIMPL.

HRESULT LoadCmdFromProprietaryGrammar(REFGUID rguidParam,const WCHAR* pszStringParam,const void* pvDataParam,ULONG cbDataSize,SPLOADOPTIONS Options);

Parameters

rguidParam
[in] Unique identifier of the grammar (type GUID). The GUID will be used by the application and the SR engine to uniquely identify the SR engine for verifying support.
pszStringParam
[in] Pointer to the string command. The string can be used by the application and the SR engine to specify which part of a grammar to utitlize.
pvDataParam
[in] Pointer to additional information for the process. SAPI will handle the marshalling of the data to the SR engine.
cbDataSize
[in] Size, in bytes, of information specified by pvDataParam.
Options
[in] Value indicating if the file should be loaded dynamically. Possible values are defined for the SPLOADOPTIONS enumeration. This value must be SPLO_STATIC.

Return Values

The following table shows the possible return values.

Value	Description
S_OK	Function completed successfully.
E_INVALIDARG	pszStringParam or pvDataParam is invalid or bad. Alternatively, Options is not SPLO_STATIC.
FAILED(hr)	Appropriate error message.

Remarks

When an application calls this method, the currently loaded CFG or proprietary will be unloaded.

Example

HRESULT hr = S_OK;
// create a new grammar object
hr = cpRecoContext->CreateGrammar(GRAM_ID, &cpRecoGrammar);
// Check hr
// load our proprietary grammar
hr = cpRecoGrammar->LoadCmdFromProprietaryGrammar(
                             GUID_MyProprietaryGrammarType, 
                             NULL, 
                             bGrammarData, 
                             ulSizeOfGrammarData, 
                             SPLO_STATIC);
// Check hr
