multi array sort

multi array sort

multi array sort

(OP)
I have this:
        v(0, 0) = 4
        v(0, 1) = 100
        v(1, 0) = 5
        v(1, 1) = 800
        v(2, 0) = 2
        v(2, 1) = 200
        v(3, 0) = 6
        v(3, 1) = 50
        v(4, 0) = 1
        v(4, 1) = 550

And I want this:
v(0,0)= 1
v(0,1)=550
v(1,0)= 2
v(1,1)=200
v(2,0)= 4
v(2,1)=100
v(3,0) = 5
v(3,1)=800
v(4,0) = 6
v(4,1)=50

How can I code it?

RE: multi array sort

Dear Enque,

Your problem is to sort a group of records, on the value of a particular column.

I do not know what your program exactly does, but I think it collects multiple sets of related data, and analyzes them.  In order to solve this type of problems systematically, you need to understand any (or both) of the two following concepts.

1. User-defined data-structures
2. Database

These topics are a bit elaborate, so cannot be explained here.  But, these are explained in any intermediate-level VB book.

I could send an example code for solving this, but for some reason I consider that pointless, without explaining the concept.

RE: multi array sort

Personally I would use VB to create an Access database with your table in it and then use the Jet functionality to do the sorting. It may not sound efficient but computers are fast and the functionality for sorting that a database gives is worth it. And using a db you get and filtering and storing between sessions and much more.

RE: multi array sort

Hi, You could use a collection object, where the number 1,2,3,etc is converted into a string and used as the key, the larger number is used as the value.

e.g.

Dim ccol As Collection
Set ccol = New Collection
' note that the order that the data is entered is unimportant
ccol.Add Key:=Str(2), Item:=200
ccol.Add Key:=Str(1), Item:=550
' ...

Debug.Print ccol(Str(1))
Debug.Print ccol(Str(2))
' ...
