Access arrays via for next loop

P: 5
I have 5 arrays, named array1 array2 array3 array4 array5. They are integer arrays each with 5 elements in them. I want to access all the elements in all the arrays using a for next loop,the pseudo code goes something like this:

Expand|Select|Wrap|Line Numbers
  1. for i = 1 to 5  'this loop calls each array
  2.  for j = 0 to 4 ' this loop calls each element
  3.      if array (i,j) then 
  4.         ' code goes here 
  5.     end if
  6.  next j
  7. next i
How would i do that please? Again, thanks for all and any help.

You seem to have a handle on it. What part exactly are you having a problem with? Is it that you don't know the actual syntax for a 'for loop' in VB?

Welcome to learning a programming language! It's always good to have people join the ranks. You will find a LOT of introductory 'how to' websites by doing a little googling. But your most valuable resource for Microsoft languages such as VB or C# would be the MSDN itself.

Hi and thanks for your reply. My struggle is with the syntax in this line of pseudo code

Expand|Select|Wrap|Line Numbers
  2. if array (i,j) 
Instead of having to name each array directly in the loop, I want the loop counter to be used so that the above line is saying at the first pass of the i loop,
Expand|Select|Wrap|Line Numbers
  1. if array1 , element j
then on each subsequent pass of the i loop the array in question becomes
array2 array3 array4 array5 . Thats the bit I'm not sure about. Hope I've explained myself clearly and if you can help then many thanks.

if you have five different arrays, then the nested loop approach you have is how you do it.

If you have a single array, five elements wide, then you could do it with a couple index counters

ArrayName[Index1, Index2, Index3, Index4, Index5]
