);

Parameters

pbstrLanguage
[out] Returns the name of the language that implements the code at this document context.

Example

The following example shows how to implement this method for a simple CDebugContext object that exposes the IDebugDocumentContext2 interface.

HRESULT CDebugContext::GetLanguageInfo(BSTR* pbstrLanguage, GUID* pguidLanguage)
{
    HRESULT hr;

    // Check for a valid language argument pointers.
    if (pbstrLanguage && pguidLanguage)
    {
        *pguidLanguage = GUID_NULL;
        *pbstrLanguage = SysAllocString(L"Batch File");
        if (*pbstrLanguage)
        {
            *pguidLanguage = guidBatLang;
            hr = S_OK;
        }
        else
        {
            hr = E_OUTOFMEMORY;
        }
    }
    else
    {
        hr = E_INVALIDARG;
    }

    return hr;
}
