Hi there;
I have a simple question: i'd like to randomize numbers (eg between 1-10) and like to check whether the generated number has already generated previously, and if so, then generate a new random number, and so on, until each number has been chosen once. In this case, the randomization should restart, reseting all previously chosen numbers.
Can anyone post me a code sample
thnx for helping me out;

I think the first link is what you are really after

You are looking for a shuffle sort. Here is some sample code in a Console application that randomly sorts numbers from 1-10 without duplicates:
Dim x, mix, temp As Integer
Console.WriteLine("Shuffle Sort - Random numbers without duplicates")
Console.Write("How many numbers (up to 20) do you want to shuffle ")
Dim rndarray(10) As Integer
Dim randnum As Random = New Random()
For x = 1 To 10
rndarray(x) = x
Next x
Console.Write(vbCrLf & "10 random numbers w/o duplicates.")
Console.WriteLine("Enter to repeat, any other key to stop." & vbCrLf)
Do
For x = 1 To 10
mix = randnum.Next(1, 11)
temp = rndarray(mix)
rndarray(mix) = rndarray(x)
rndarray(x) = temp
Next x
For x = 1 To 10
Console.Write("{0} ", rndarray(x))
Next x
Console.WriteLine(vbCrLf)
entry = Console.ReadKey(True).KeyChar
Loop While entry = Chr(13)
Console.WriteLine()
