Call to Rnd() generating the same number

Question

When I set up this bit of code, every time I debug the software it generates the same number. Can anyone tell me why this is happening?

dim value as integer
         


        

Answer 1

You need to call

Randomize()

Before you call Rnd() to initialize your random num ber generator. If you don't, every time that you run the program you will get the same sequence of numbers.

Example:

dim value as integer
Randomize()
value = (CInt(Int(100 * Rnd())))
messagebox.show(value)

The reason is that the Rnd() will always use the same seed to start the sequence. If you want to read more about it, is very well explained explained here: https://msdn.microsoft.com/en-us/library/8zedbtdt(v=vs.90).aspx
