spai中LoadCmdFromFile总是失败！

[amatuer_feier]

我用sapi5.1，想做个语音识别的小程序但是总是出问题
if (FAILED(m_pRecoContext->CreateGrammar(101, &m_pCMDGrammar)))
{
MessageBox(_T("Failed to create instance of ISpRecoGrammar!"));
return FALSE;
}
HRESULT hr = S_OK;
hr = m_pCMDGrammar->LoadCmdFromFile(_T("E:\\MyProject\\SpeechTest\\Debug\\email.xml"), SPLO_DYNAMIC);
if (FAILED(hr))
{
int e = GetLastError();
MessageBox(_T("Failed to Load CMD!"));
return FALSE;
}
if (E_INVALIDARG == hr)
{
MessageBox(_T("Invalid File Name or param"));
}
这个地方，总是弹出"Failed to Load CMD!"，但是不会弹出"Invalid File Name or param"，找不到原因。
GetLastError返回的也是0，说明是正常返回
有谁用过sapi的，帮忙解答一下，谢谢了！

光顶没有，有人解答没？

放到同一目录下，然后直接调用

Like this

 HRESULT hr = S_OK;

    // create a new grammar object
    hr = cpRecoContext->CreateGrammar(GRAM_ID, &cpRecoGrammar);
    // Check hr

    // deactivate the grammar to prevent premature recognitions to an "under-construction" grammar
    hr = cpRecoGrammar->SetGrammarState(SPGS_DISABLED);
    // Check hr

    // load the email grammar dynamically, so changes can be made at runtime
    hr = cpRecoGrammar->LoadCmdFromFile(L"email.xml", SPLO_DYNAMIC);
    // Check hr

    SPSTATEHANDLE hRule;

    // first retrieve the dynamic rule ADDRESS_BOOK
    hr = cpRecoGrammar->GetRule(L"ADDRESS_BOOK", NULL, SPRAF_Dynamic, FALSE, &hRule);
    // Check hr

    // clear the placeholder text, and everything else in the dynamic ADDRESS_BOOK rule
    hr = cpRecoGrammar->ClearRule(hRule);
    // Check hr

    // add the real address book (e.g. "Frank Lee", "self", "SAPI beta", etc.).
    // Note that ISpRecoGrammar inherits from ISpGrammarBuilder,
    // so application gets the grammar compiler and ::AddWordTransition for free!

    hr = cpRecoGrammar->AddWordTransition(hRule, NULL, L"Frank Lee", NULL, SPWT_LEXICAL, 1, NULL);
    // Check hr
    hr = cpRecoGrammar->AddWordTransition(hRule, NULL, L"self", NULL, SPWT_LEXICAL, 1, NULL);
    // Check hr
    hr = cpRecoGrammar->AddWordTransition(hRule, NULL, L"SAPI beta", NULL, SPWT_LEXICAL, 1, NULL);
    // Check hr
    // ... add rest of address book

    // commit the grammar changes, which updates the grammar inside SAPI,
    //    and notifies the SR Engine about the rule change (i.e. "ADDRESS_BOOK"
    hr = cpRecoGrammar->Commit(NULL);
    // Check hr

    // activate the grammar since "construction" is finished,
    //    and ready for receiving recognitions
    hr = cpRecoGrammar->SetGrammarState(SPGS_ENABLED);
    // Check hr

C/C++ code
HRESULT hr= S_OK;// create a new grammar object hr= cpRecoContext->CreateGrammar(GRAM_ID,&cpRecoGrammar);// Check hr// deactivate the grammar to prevent premature recognitions to an "under-construction" grammar hr= cpRecoGrammar->SetGrammarState(SPGS_DISABLED);// Check hr// load the email grammar dynamically, so changes can be made at runtime hr= cpRecoGrammar->LoadCmdFromFile(L"email.xml", SPLO_DYNAMIC);// Check hr

[/Quote]
还是在hr = cpRecoGrammar->LoadCmdFromFile(L"email.xml", SPLO_DYNAMIC);
这个地方不通过，返回值hr为-2146697211（0x800c0005）
搞不懂这个返回值是什么意义

再顶

[MoXiaoRab]

On 32-bit platforms, the HRESULT data type is the same as the SCODE data type. On 16-bit platforms, an SCODE value is used to generate an HRESULT value.

An HRESULT value is made up of the following fields:

A 1-bit code indicating severity, where zero represents success and 1 represents failure.


A 4-bit reserved value.


An 11-bit code indicating responsibility for the error or warning, also known as a facility code.


A 16-bit code describing the error or warning.

[MoXiaoRab]

去MSDN查各个位的对应

[amatuer_feier]

很无语，facility code里面都没有出现跟我这里对应的值。。。
啊，我要崩溃了！
