if you need info on a macro action and can't find it in Access Help, try VB Help. press Alt+11 and use the 'Ask a Question Box' in the top right corner or Help->Microsoft Visual Basic Help.
is there any online tutorial for macro? i've been wanting to learn. I tried searching over the net but unlucky to find a decent one. Thanks in advance guys..
Just search Google for Access Macro. Excel and Word also have macros but tye are complete unrelated to Access Macros
Unless things have changed you won't get books specific to Macros. What you buy is a book or books on Access and Macros will be one of the sections of the book like Tables, Forms etc.
