Coding question!

Warrio · May 27, 2005

Hello! This is only a question about coding,

how is it possible to calculate the possible combinations between a series
of members?

In addition the total number of the members of each series should not exceed
a fixed number.

For instance:

-the members are: (1; 2; 7; 9)

-each series must contain 3 members (can be 2, 3, 14 or any
number)

The result would be:

Series1: 1; 2; 7

Series2: 1; 2; 9

Series3: 2; 7; 9

I tried with 3 loops with a collection structure, but I differentiate my
head from feet anymore.

Thanks for any suggestion!

Hi Warrio,

Search (using Google or another engine) for

vb generate unordered combinations algorithm OR code

or similar and you'll find some examples.

Thanks John!
and that's what I found in msdn articles
a code in c, that generates combination of n members on series of k elements
http://msdn.microsoft.com/library/d...ry/en-us/dv_vstechart/html/mth_lexicograp.asp

it answers the question below except that this code starts the combinations
from 0 to n-1, I will have to modify it in order to put any members the user
wants

Best regards

That's easy: put the members into an array(0..k-1) and use the numbers
generated by the n of k code to select elements from the array.
