Avoiding date/time formulas in views

Having date/time formulas like @Now causes servers to overload by refreshing views all the time. Here is what you have to do to avoid this.

Put this code in the postopen of your database.

@SetEnvironment("MyDate";@Text(@Now))

When a user opens the database, it will put the today's date in his local notes.ini file.

If you have a column or the selection formula in the view that needs to control the today's date, you just have to recuperate the value in the notes.ini by using this code:

w_date:=@TextToTime(@Environment("MyDate")); etc.
