Changing the Backcolor property of a Listbox should be exactly as I show it in class for EVERY version of Access.

ListboxName.Backcolor = VALUE

I like using the RGB function now instead of the codes. You can specify how much Red, Green, and Blue you want, so:

ListboxName.Backcolor = RGB(0,0,0) ' black
ListboxName.Backcolor = RGB(100,100,100) ' gray
ListboxName.Backcolor = RGB(255,255,255) ' white
ListboxName.Backcolor = RGB(255,0,0) ' red

And so on.

I think we are not talking about the same thing. The back color property of the list box is not the problem. In the calendar form, the days that are not part of the actual month are grayed out using code that refers to the current month of the Calendar Control. Since there is no calendar control available in Access 2016, the code can not get a Month value and gray out the days that are not part of the current month. My apologies if my first question was not very clear.

I'm pretty sure I address this in a later video. Have you finished the whole seminar yet?

I am at the report stage, lesson 9, but I have to solve the issue with the missing calendar control in Access 2016. Because there is only one text box control to pick a date, the code creates an issue in that, by refering to that single text box, the code substracts one day from the scheduled appointment date.

Did you see the two addendums (top of the page)?

Thank you very much, I will go through the two addendums.
