giving notification to users on the form

[shod90]

Dear All,
Kindly um working on timesheet application , Everything is running perfect and smoothly , But um thinking to put an option.
This option is to pop out a window if the user didn't input his data in one day, So if he put data on tuesday and he forgot to put on Wednesday when he login on Thursday to put his data , There should be a window or message box " Please Note that you didn't insert 'The date' data ".
Is it applicable ?
Thanks in advance.

capture the userID when the form opens to enter time
txtBoxUsr = Environ("Username")

then pull a query that shows missing dates < today
show the query in a list box on the screen.
if lstBox.listcount >0 then msgbox "You are missing entries for these dates"

Actually , I gave it a try but unfortunately , the query gives me duplicated records for all the dates which was entered by the users , Also how to control only a specific user with his dates only , not all the dates !

what i mean that i have table like this:

username Date Comments
Joan 20/3/2016 any comment
Joan 22/3/2016 any comment
Ann 21/3/2016 //
Ann 23/3/2016 //
Joan 23/3/2016

so in Joan's records there is 21/3/2016 is missing and in Ann's records there is 22/3/2016 is missing
how to generate these dates in an query and show each users his missing date ?

Do you have a specification (some details) for WHAT your application will support?
How do you deal with Holidays?? Are there codes for WHAT project people are working on?
What about Leave(Vacation, Sickness......)?

Date is a reserved word in Access.

Hope this helps put the issue(s) into context.
Good luck.
