Expression returns false even though it should return true

Hi, I'm trying to check if a date is before now or after NOW. While debugging i can see that the expression doesn't return true even though it should.

.Planned

.Planned

.Planned

.Planned here?

right, really hard to see

P

Pobiega•11/21/22, 3:50 PM

well, thats... very weird.

I've never in my 20 years of programming encountered an actual "true is false" bug so I doubt we are seeing one here either

PPobiega right, really hard to see 😄

hahah sorry, yea i'm kind of scratching my head.

M

MackeOP•11/21/22, 3:51 PM

yea there must be something i'm doing wrong

There was another post yesterdya where the debugger showed "" != "" so could be a similar thing here?

Assuming it's 10:52 or earlier where op lives then it doesn't make sense

M

MackeOP•11/21/22, 3:52 PM

it's 12.52 pm here

T

TheBoxyBear•11/21/22, 3:53 PM

Planned is for 11:40

M

MackeOP•11/21/22, 3:53 PM

yea

M

MackeOP•11/21/22, 3:53 PM

I guess i'll explain

M

MackeOP•11/21/22, 3:53 PM

i have a list with objects and if time has passed past the .Planned property i want to remove it from the list

T

TheBoxyBear•11/21/22, 3:53 PM

So even if DateTime.Now advances, it wouldn't change the outcome

M

MackeOP•11/21/22, 3:54 PM

So i have objects i need to remove that are tomorrow and before the time that is now

Does it run the if anyway with a breakpoint?

T

TheBoxyBear•11/21/22, 3:55 PM

If so, then the debugger is messed up dviperShrug

M

MackeOP•11/21/22, 3:55 PM

there's no exception

M

MackeOP•11/21/22, 3:55 PM

and i'm not expecting there to be one

T

TheBoxyBear•11/21/22, 3:55 PM

No exception, just if it enters the if block

M

MackeOP•11/21/22, 3:56 PM

i'll check one sec

M

MackeOP•11/21/22, 3:56 PM

oh my god

M

MackeOP•11/21/22, 3:56 PM

i just saw it

M

MackeOP•11/21/22, 3:56 PM

i'm so stupid

M

MackeOP•11/21/22, 3:57 PM

It removes the objects that are before now

M

MackeOP•11/21/22, 3:57 PM

but not after today

M

MackeOP•11/21/22, 3:57 PM

But it's because I'm first checking if it's less than now and then checking if it's more than today

M

MackeOP•11/21/22, 3:57 PM

so since it's not less than now it's never gonna reach the second if block

TTheBoxyBear No exception, just if it enters the if block

M

MackeOP•11/21/22, 3:58 PM

it's at moments like this i'm wondering if i really should be doing this lol

TheBoxyBear•11/21/22, 4:00 PM

We all make dumb mistakes

quick question, do list indexes start at 0 or 1?
