DateTime question

rbuser

I have a DateTime variable and I assigned a date value to it.
How I can increment this value by 1 day (or number of days).
I Delphi I would just say MyVar:=MyVar+1. But this does not work in
RBuilder.

This does work the same way it does in Delphi. In the variable's OnCalc
event increment it's Value property, i.e.

ppVariable1.Value := ppVariable1.Value + X

where X is the increment/decrement value. 1 corresponds to 1 day (5 is 5
days and 1/(24*60) is 1 min, etc)

I'm using TDateTime variable declared in OnPrint procedure for a label, not
ppVariable. And sometimes it works and sometimes it does not. It works if I
use code like this:

MyVar:=MyTable['Date_Field']+10;

But this does not work:

MyVar:=MyTable['Date_Field'];
MyVar:=MyVar+10;

TDateTime is just a Double type so there should be no difference between
those two statements as long as the data field is being returned as the
appropriate type.
