SAPI 5.1
ISpProperties::SetPropertyNum
ISpProperties::SetPropertyNum sets a numeric property corresponding to the specified name.
HRESULT SetPropertyNum(
const WCHAR *pName,
LONG lValue
);
Parameters
- pName
- [in] Null-terminated string containing the property name. Valid values are listed in the SR Properties section of the SAPI 5.0 SR Properties White Paper.
- lValue
- [in] The property value to set.
Return values
| Value | Description |
|---|---|
| S_OK | Function completed successfully. |
| S_FALSE | SR engine does not support specified property name. |
| E_INVALIDARG | One or more parameters are invalid. |
| FAILED(hr) | SR engine returned specific error. |
Remarks
If the SR engine supports the property, SAPI will fire a property-changed event (see SPEI_PROPERTY_NUM_CHANGE) to all interested recognizer contexts (ISpRecoContext). Broadcasting the corresponding event notifies any recognizer contexts that had interests in the property (see CSpEvent::PropertyName and CSpEvent::PropertyNumValue).
