Hi there,

Is there a fast way to get the highest value from an array?

I've got the array strStorage(intCounter)

I tried something but it all and's to nothing

If someone good helpme, TIA

Jan,

It is with arrays .Length and with collections .Count

However, try to avoid the base Array class direct. Not in connection with
the previous, as a strange behaviour has that class in Visual Basic Net the
effect that this class (and everything that derives from it) creates one
item more than you tell that it has to creat.e
\\\
dim a(10) as string
///
Creates 11 strings. Therefore when I am using this class and want 10 items I
do
\\\
dim a(9) as string
dim b as integer = a.length ' gives 10
///
Better is in my opinion, when your want to use array has not to use those
fixed ones however the Arraylist.
\\\
dim ar as arraylist.
///

It is dynamic however is it as well using the .length to get the items in it

I hope this helps,

Cor

Hi There,

When you say the highest value from the array, this could mean more than one
thing.

1.) You could be asking for the highest numerical value from all values in
the array

2.) You could be asking for then top index value or ( ArrayName.Length ) of
the array.

3.) In an array, you could be asking for the value with the highest index.
For example, if you set up an array of strings, if could be the highest
non-empty string., assuming elements were filled contiguously from 0 up.

Can you be more specific, or do my questions provide you with some sort of
answer ?

youre write about that.

i ment the first option in your list.
so, I want the highest numerical value from all values in the array!

Sorry, about the confusion

Jan

Jan,

The method I would use.

If this is what the OP is looking for then I would suggest that they may
consider implementing a class for this functionality which may set a highest
value property each time an element is set. This way one can be sure to
retreive it in the fastest time possible, rather than iterating through all
the elements.

This of course could be counter productive as it adds more processing time
to setting the elements in the first place, its a matter of judging which
operation is done most frequently, the search or the setting ? Some
impirical data may be collected in order to assess the impact or both
methods and choose whichever is most appropriate for this need.
