Happy 2015, everyone! Sorry that I didn't post much during December. The holidays kept me quite busy with both some work projects and family. But, January has a LOT of stuff coming, so hold on to your hats.
I just released Access Expert 27. This was originally going to just be one class, but it turned out to be over 3 hours of material, so I broke it up into two. X27 is available now on the web site. I've got all but one of the lessons finished for X28 (I decided to add one more thing) and then I'll release that in a couple of days.
X27 covers a lot of good, solid DateTime fundamentals. Some of it we've learned in earlier classes, but I really just skimmed the surface of working with dates previous to this. You get a lot more detail on how dates and times work. Check out the X27 outline for details.
X28 should be available in a couple of days. This covers mostly NEW material, including functions you've never seen before in my classes: WeekDay, DateAdd, DateDiff, DatePart, DateSerial, and more. We'll see how to do things like figure out the last day of next quarter, the first day of last month, how many days are in February of 2016, and so on. I'll post the full outline of everything I've covered so far below just so you can look it over.
Now, a few weeks ago when I told everyone that I would be covering dates and times in X27, you posted some things you wanted to see in the Forums. I tried to include as many of the things as I could in these two classes, but some of them require VBA programming, which I'm not including in the Expert series. So, I'm going to put together a short seminar with these solutions in it. I'll call this the Advanced DateTime Seminar and it's going to include:
- Calculating the number of WORK days between two dates (excluding holidays and weekends)
- Updating a timestamp when a record is EDITED (adding is easy, EDITED not so much)
- A to-do list with buttons to move to the future (30 mins, 1 day, 1 month, etc.)
- A "popup" reminder for that to-do list (you have an appointment in 30 minutes)
- Some advanced calculations like "how many Mondays are left this month?"
If you can think of anything else you'd like to see covered in this seminar, then please let me know. Email me or post it here in the Forum as a comment below. I'll add as much stuff as I can.
I expect to have X28 ready in the next couple of days, and then the Seminar a few days after that. I have some other projects I'm working on too, concurrently, so I'll do my best to get these out ASAP. For those of you on the Waiting List for X27, you should have already received your copy. Even though I plan to release X28 on the web site in the next couple of days I'm going to wait until next week to process the Waiting List orders for it, to give you time to finish X27 before the next class comes at you. If you don't want to wait, feel free to order it online (you won't get a 2nd copy) or email customer service and we'll send it to you.
OK, here's what I have recorded so far for the NEXT class (X28). These videos are FINISHED.

What Day of the Year is it?
How Many Days Remaining in Year?
Exact Age / Anniversary Calculations
TimeSerial() Function Just like DateSerial
CDate() Function - BOTH date AND time
Useful to convert strings to DateTime values
I still have one more video to record (plus the bookends). I'm going to cover a few more examples, including some sample projects. Here's what I have planned (not set in stone):
- List of birthdays in the next 60 days
- List of birthdays in the next calendar month
- Update query: mark birthday card "sent"
- List of appointments for the week with buttons to move "forward" and "back" one week at a time
- List of recurring appointments. Mark an appointment FINISHED and it resets for a future date
- Use validation rules to prevent ShipDate being before OrderDate
Again, if you have any ideas, let me know.
