generating random numbers in visual basics

Question

I am using a random number generator in my program, however it keeps returning the same value (0.71) every time i run the program.

code:

number = FormatNumber(Rnd(1), 2)
    rdmlabelTxt.Text = number.ToString

is there a way to produce a different random number when starting the program? thanks.

Answer 1

According to Microsoft "the same number sequence is generated" when you don't give a parameter. The article also suggests to "Before calling Rnd, use the Randomize statement without an argument to initialize the random-number generator with a seed based on the system timer."

I think this will solve your issue - let us know.

Answer 2

You are required to write a for loop to be able to generate different numbers

For i = 1 to 100
number = FormatNumber(Rnd(1), 2)
Cells(i, "A").Value = number
next i

Answer 3

You just have to use Randomize() call before your codes.

Randomize()
Dim number As Double = 0
number = FormatNumber(Rnd(1), 2)
rdmlabelTxt.Text = number.ToString
