ISpeechRecoGrammar* Grammar;
Grammar=SpSharedRecoContext1->CreateGrammar(Variant(0));
WideString Path="d:\\ASR\\sol.xml";
Grammar->CmdLoadFromFile(Path,SLODynamic);
Grammar->CmdSetRuleIdState(0,SGDSActive);

我在用SAPI5.1时，在Grammar-> 指向属性，方法时都出错
Access violation at address77F8F281 in module 'ntdll.dll'.write of address 00000010

各位老大，，帮帮忙

ISpSharedRecoContext * SpRecoContext;
ISpeechRecoGrammar* Grammar;

if ( SUCCEEDED(::CoInitialize(NULL)) )
if (::CoCreateInstance(CLSID_SpSharedRecoContext, NULL, CLSCTX_ALL,
IID_SpSharedRecoContext, (void **)&SpRecoContext) != S_OK)
Grammar = SpRecoContext->CreateGrammar(1);

试试看, ISpeechRecoGrammar 好象要用 ISpSharedRecoContext 来建立.

CLSID_SpSharedRecoContext

对象没有初始化，还不能用，你当此进行，而不能简单地使用 new ISpeechRecoGrammar 。

ISpeechRecoGrammar* Grammar = NULL;
if ( SUCCEEDED(::CoInitialize(NULL)) )
if (::CoCreateInstance(CLSID_SpeechRecoGrammar, NULL, CLSCTX_ALL,
IID_ISpeechRecoGrammar, (void **)&Grammar) != S_OK)
Grammar = NULL;
