it may not be one your management or IT people may want to implement, so you should check with them first.
I don't use Access but I do use Word and Excel and so the same options will apply.
The warning message is about Macros. Macros are bits of programming within any document, excel or access file that hold VB coding. The warning is because Macros can hold viruses which, when the macro is invoked, can spread into the computer.
In Tools > Options, Security tab look for the Macro Security button and make your choices of macro security there. If those choices are not available, then speak to the IT people as they may have disabled the options.
Our office uses Access XP/2002. I have installed Office 2003 on my PC and plan to roll it out to the rest of our small office.
One "annoyance" I have noticed is that if I try to open one of our Access databases with Access 2003 I always initially get this message:
"Security Warning. This file may not be safe if it contains code that was intended to harm your computer. Do you want to open this file or cance; the operation".
I hit "Open" and all is fine. I can "live" with this, but I know I'm going to get some co-workers who will desperately want to eliminate this message. I have looked around and can't seem to find a way to do that.
Please let me know if there is a way, or if not, tell me so so I can say with confirmation that this just has to be. Thanks!
