Remarks
VODBSetFilter() is like DBSetFilter() but is strongly typed.
This function, however, does not call the error handler and will not, therefore, produce a runtime error message or create an error object if it fails. Thus, it may be important to check the return value to determine if the function succeeded.
The global structure, StrucErrInfo, will contain needed information regarding any error that occurs. See DBSetFilter() for more information and an example.
