Random number generation

[Michiel Spape]

Hi,
What David said, or: just shuffle an array with the numbers 1 to 100.

Dim i as Integer
Dim Rand100(1 to 100) as Integer
For i = 1 to 100
	Rand100(i) = i 'fills array
Next i

RandomizeArray Rand100 'randomises

For i = 1 to 100
	Debug.Print "Random number is = " & Rand100(i) 'show output
Next i

Subject: Random number generation

Hi,

I am working on an experiment in which I want to generate 100 random
numbers between 1 - 100, but a number should not be repeated. Say if 1
is generated then it should not be generated again. Basically I want
all 100 numbers between 1 and 100 without any repetetion and that too
in a random manner.

Right now I am using the script

Dim i as Integer
Dim Rand as Integer

For i = 1 to 100

Rand = Random(1,100)

Debug.Print "Random number is = " & Rand

Next i



This is giving me random numbers between 1 and 100, but the numbers
are repeated.

Please let me know if there is any logic of generating random numbers
without any repeat.

Any help is really appreciated.


Regards
Shivani
