Not gernating same number twice in a row

there is actually a list of numbers on what is called "the table of random digits" I had to use it in Statistics... and it's a table of random digits basically that were computer generated... kinda neat actually

Hey aaj2008

here is my problem
To create a program that generates 7 random numbers display it in 7 labels and there a button if u click it picks out the highest number

Are you trying to create a computer program? Or are you just using one? Or are you trying to create this on like a TI calculator?

on a TI calculator there is an application to pick random digits and you can enter how many digits you want and tell it to give you the highest one first...

I'm trying to create it on Vb 6.0. the random number should be stored in a variable. Here is what I got so far.

Option Explicit
Dim random(0 To 6) As Integer
Dim old(0 To 6) As Integer
Dim Index As Integer
Dim I As Integer




Sub generate()

For I = 0 To 6
random(I) = Int(Rnd * 25 + 1)
If random(I) = old(0 Or 1 Or 2 Or 3 Or 4 Or 5 Or 6) Then
random(I) = Int(Rnd * 25 + 1)
End If

old(I) = random(I)
lblnum(I).Caption = random(I)
Next I



End Sub
Private Sub btnrandom_Click()
generate
End Sub

This doesn't work. I think I need to create a loop where it loops till it finds a random number that has not been generated before

I don't really know actually... it looks like it should work to me... umm.. I'm getting tired and about to head to bed but I will do a little research and ask one of my professors in the morning... but yeah the loop might help but not sure

Thanks for your effort. Appreciate it

Look at these links.. Should help out bunches

There generally needs to be a statement like Randomize to reset the seed to make them more random.

To avoid generating the same number twice, you need to check all the numbers and see if it was generated before.

I believe the statement is int(25*RND)+1 for 1 to 25. Since RND is a number between 0 and 1. I don't think it includes 1. Check.
