Randomization

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

i was wondering, how would you randomize numbers in visual basic. i tryed to learn different algorithms, but they keep giving me the same number when i run the perogram. anyway, any help will be greatly apreciated

Put the following line in your Form_Load:
 Randomize 

And then you can use 
Rand(1, 10) for random integers

or 

Rnd for real numbers (that you'll have to scale to suit your purpose).

it says "rand" is not a defined function  :?

codemage, that's not really it.  The primary random functions are :

Randomize()
and
Rnd()

Randomize shoudl just go at the beginning to set the seed.  
Rnd returns a random real between 0 and 1.  Thus, you can create your own function to output a random integer in a given range.

OMG, my bad.  I'm accustomed to using custom modules & libs for too many of these "should be standard" libraries.

My "Rand" function is as follows:


Public Function Rand(Low As Long, High As Long) As Long
  Rand = Int((High - Low + 1) * Rnd) + Low
End Function
