Return Values

[C++] This method returns an HRESULT indicating whether it completed successfully. See the Error Values section for more details.

[Visual Basic] If this method completes successfully, it returns a string Variant that contains the date value formatted as a string; otherwise, NULL is returned.

Error Values

[C++] This method returns S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.

[Visual Basic] This method sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.
