IErrorLookup::GetHelpInfo

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), 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.
