im having problems using the array insert at bottom command.
i am new to DBPro and the help files dont help much.
the arrays are declared as follows:



I think it is this code that is not working; i thought it may have something to do with how the arrays are declared but have never used these commands before.

Good thought but that is perfectly legal, that's not the problem.

What exactly is it that does not work?
That command adds a new index at the end of the array, which you then have to fill yourself.
If it does indeed not add another element, then you could always try re-dimensioning the array (which you have to do if you are using an UDT array anyway), like so:

I took the zeros out and it works now, interesting that both methods are legal and one does not work. It was not adding another element to the array, i used array count to check.
Could this be a problem with dark basic?

Thanks for the help.

Doesn't doing that erase the contents of the array? Also, I've used ARRAY INSERT AT BOTTOM on UDT arrays lots of times.


@Reggie: That code should work. Could you tell us what it is you are trying to do with that, exactly?

No, it doesn't.
Yes, apparently you can, but it messes up any strings in there I think. Or maybe that only happened when undiming them... I can't really remember, but I recall there being some reason that you should redim your udt arrays instead of inserting elements to them. Have always done so since anyways, maybe it isn't necessary after all
Anyways, it works quickly and leaves all data intact, so there is no downside to doing it.

Wow I didn't know the DIM command didn't erase the data! That's good to know...

By the way, this works. My game relies heavily on it . Also, the ARRAY DELETE ELEMENT command can be used as well (and it automatically shifts everything else in the array down which is great)



Maybe you were thinking of multi-dimensional UDT arrays, in which case the DIM method would have to be used.

Now that you say it, that was it. So I've been shifting my (single dimension) arrays manually for a long time in vain then..
Well, as I said, it works just fine anyway, so no big problem, apart from some extra work then

Thanks for pointing that out though! Now I can expand multi-dimensional arrays .

Anyway, until Reggie12 tells us what he's after we can't really help much...

Its all working now, the problem seems to go away when i take the zeros out; probably something to do with accessing it like a dynamic array rather than a list.
Thanks for the help
