Hi guys,

I am having serious problems debugging an error which occurs in my program. I enclose the code. The error happens when the "TRAIN" button is pushed. This leads to a sub which is called ShufflePattern in which an array is randomly shuffled. I put in a msgbox to trace the error but I cant find why the error says "out of range".
Would somebody take a look and enlighten me plz...
Ignore the rest of the code. It's about neural networks.....
thnx in advance

The error happens because RowArray is empty:

RndNr = RND(0,RowArray.Count)

so RndNr = 0

ShuffleData(c) = RowArray.Item(RndNr)

RowArray.Item(0) doesn't exist => error!

But I haven't searched yet, why RowArray get's empty.

But RowArray gets initialized and filled in the sub InitValues which is called before sub Output.....

Yes, but you have 20 rows in your table and so you add 20 entries to you RowArray:
FOR RN = 0 to Rows-1
RowArray.Add(RN)
NEXT
If you look at you debug messagebox
count goes from 20 to 1
and
c goes form 0 to 19

Now all of your (20) added rows are removed from the RowArray.

And now, the Sub ShufflePattern is called again (I don't know why, I haven't analysed your code yet) ... but there is no entry in th RowArray left.

Guys,

You are magnificent!! I had totally overlooked the loop in which ShufflePattern in repeated without re-initializing the array. Thanks very much, works like a charm now...... remains the task of speeding up the code now....
thnx again!
