Giving Random Values to an Array

-----------------------------------

I am having problems with the syntax in Visual basic to give an array that holds 10 values to assign it 10 random numbers.

In Turing you can do it like this

var x :array 1..10 of int
for a:1..10
x(a):=Rand.Int(1,10)
end for

In visual basic...so far I've got

Dim xArray(9) as Integer

Thanks for any help, in advance.

I'll advise you to check out the tutorials.

stick for loop/while loop here with counter i, going from 0 to 8
xArray(i) = Int((HighestValue - LowestValue + 1) * Rnd) + LowestValue

stick randomize in the form_load to get diff random sequences

i like the bunnie, i have 2 fwuffy bunnies with me right now:D

Here is a useful function that is similar to turing's Rand.Int. 
Private Function randInt(ByVal x As Integer, ByVal Y As Integer)
   If x > Y Then
      Error (3)
   End If
   randInt = Int(Rnd * (Y - x + 1)) + x
End Function

hey man, im pretty new to arrays.. but i think it would be something like this??

Dim intX(1 to 10) as integer
dim intCount as integer

for intCount = 1 to 10
intX(intCount) = randint(1,10)
next intCount


im not relaly sure about the randint part because i haven't used it for a long time. lol
just try tht.

Dim xArray(9) as Integer  defines a 9 element array as 0-8 are the valid indices for the array.

Try this instead:
Dim xArray(10)
