The date in excel file i send is just a sample date that need to check.
So, for example, today date is 23/4/2020, i run the program, and the rule is, it will check for date in column A and compare to the date in computer when i run the program, if any of the date in column A less than 23/4/2020 (for example 22/4/2020 or 24/8/2019), the message box will show “expired”.
For another example, i run the program to check excel file 1 year later, the date in computer for 1 year later will be 23/4/2021, so now all the date in column A will be compare to 23/4/2021.
So, the rule is i will run the program to check the excel file any time, and the date in column A will always compare the date in the computer when i run the program.
sorry for my bad explanation, hope you can understand.
