Are there any functions for detecting if time is within a certain time range?

[altenbach]

Here's one possibility. It will even do the AM/PM conversion for you.

(If you want, you can leave out the ":" in the format. would make no difference)

That what was an example of the flow of logic lol. It's not the actual code I'm using

[David99999]

Alrightyyyyyyy I think I'm just gonna use this that I whipped up real quick. Probably not the best, but it'll do. Like I said, I don't have any timestamps to begin with, just strings.

This is just to get military time values, then I can use range

Hi David,

why don't you concat your input strings into one timestamp like string and use ScanFromString to parse your time?

[altenbach]

No, that's still way too convoluted and overly complicated. What if the user enter "am" instead of "AM"? (hint: it would be considered PM!) What if the user enters 55 AM? What if he enter 5 XM?

The two pseudo-numeric fields should be numeric with correct input range limits and the AM/PM could be an enum or ring.

Did you even look at my earlier suggestion?

[David99999]

Yes I did, and it appeared as though your solution needed the timestamp data type, which I don't have unless I make one myself.

Also, again, these code snippets I'm posting are just examples for how the solution could work. In my actual code, all the hours, minutes, and AM/PM's are enums.

Some fun with Scan From String and Format Into String can do the 12 to 24 hour conversion for you.

That's awesome, thank you!

The problem is still that the inputs are strings and thus cannot be easily validated for correctness. Users can type the combined works of Shakespeare in there and the result would be garbage. 😄

As I said, I would use a combination of numeric and ring inputs, where the input range is correctly defined in the control(1..12, 0..59, AM=0, PM=12).

Here's how that could look like. (I added some optional code to validate the conversion. Of course I have not tested every possible input, so test for yourself 🙂 ).
