问题 I am trying to build a procedure in my Access project that will accept either a table or a form as part of the argument. If the object is a table then it should check the table's fields; if it's a form then it should it the form's controls. I've tried using either variant or object variable types for the argument. But either way when I check the VarType() the passed variable is of type object, so I can't distinguish between them. (I'm currently passing a table as a TableDef object by the way.

You can, however, filter the data or use a query in order to find the appropriate

问题 I have linked an IBM informix database table through an ODBC connection to an Access 2010 database. My issue is that the date field in this table only shows dd/mm/yy HH:nn:ss in the Access view, where the stored data is to 1000th of a second. I can show this in Excel 2010 but not in Access 2010: is this possible? Not having this level of accuracy is preventing me making accurate calculations! 回答1: There is a similar question on another forum here. The Date/Time field type in Access does not
