Random numbers
Numbers
This FAQ will:
1) Demonstrate how to generate a single random number...
2) Show you how to generate a set of random numbers...
... between 2 given values.
[color green]You MUST initialize the Random Number Generator BEFORE selecting the random numbers. In your Form_Load() event, simply put the word Randomize, thus:[/color]
[tt]
Private Sub Form_Load()
Randomize
End Sub
[/tt]
Generate a single random number between 1 and x
[tt]Dim MyValue as Integer
MyValue = Int((10 * Rnd) + 1) [color green]' Generate random value between 1 and 10.[/color][/tt]
Generate a random number between x and y
[tt]Dim MyValue as Integer
intNumber = Int((100 * Rnd) + 150) [color green]' Generate a random number between 150 (x) and 250
[/color]
[/tt]
{Set x (the 150 above) as the lowest number. Set y (the 100 above) to the highest number - x.)
Generate x random numbers between 1 and x, store in an array
[tt]Dim MyValue(9) as Integer
Dim I as Integer
For I = 0 To 9
MyValue(I) = Int((100 * Rnd) + 1)
Next[/tt]
This will generate 10 random numbers, store them in an array (MyValue), with the numbers between 1 and 100.
Generate x random numbers between y and z, store in an array
[tt]
Dim MyValue(5) as Integer
Dim I as Integer
For I = 0 To 5
MyValue(I) = Int((70 * Rnd) + 30)
Next[/tt]
(This will generate 6 random numbers between 30 and 70, then store them in the MyValue array.)
