Returns the path of the Help file and the context ID of the topic that explains the error.
HRESULT GetHelpInfo (
HRESULT hrError,
DWORD dwLookupID,
LCID lcid,
BSTR * pbstrHelpFile,
DWORD * pdwHelpContext);
Parameters
hrError
[in]
The code returned by the method that caused the error.
dwLookupID
[in]
The provider-specific number of the error.
lcid
[in]
The locale ID for which to return the Help file path and context ID.
pbstrHelpFile
[out]
A pointer to memory in which to return a pointer to a string containing the fully qualified path of the Help file. If there is no Help file or an error occurs, the returned value (*pbstrHelpFile) is a null pointer. The memory for this string is allocated by the provider and must be freed by the consumer with a call to SysFreeString.
pdwHelpContext
[out]
A pointer to memory in which to return the Help context ID for the error. If there is no Help file (*pbstrHelpFile is a null pointer), then the returned value has no meaning.
Return Code
S_OK
The method succeeded.
E_FAIL
A provider-specific error occurred.
E_INVALIDARG
pbstrHelpFile or pdwHelpContext was a null pointer.
E_OUTOFMEMORY
The provider was unable to allocate sufficient memory in which to return the Help file path.
DB_E_BADHRESULT
hrError was invalid.
DB_E_BADLOOKUPID
dwLookupID was invalid.
DB_E_NOLOCALE
The locale ID specified in lcid was not supported by the provider.
