A while back, when trying to make a change in my Access database, which this thread is about, I discovered that if someone outside of me made any change to the program and then emailed me that change I had to:
1. I first had to open the file
2. Close it and reopen it again
3. Then open the Properties of the database as seen in the attachment
4. Then click the box that the Red arrow is point to in order for the database to work as the macros or VBA code was trying to tell it to.
I could not access that Unblock option on the first opening of a modified file which was emailed to me.
Once that block was checked, I could then access the Enable Macros option withing the database program itself to get everything working as it should.
My question, and this is very constant after a program modification, is why do I have to open the modified database twice in order to be presented with that Unblock option? I can see what it says about the file coming from another computer but have no idea why I have to open it twice.
