Generate random value between minimum and upperbound in VB.NET

 To generate a random value between a lowerBound and an upperBound, use the standard scaling formula: random() * (upperBound - lowerBound) + lowerBound for decimal numbers, or floor(random() * (upperBound - lowerBound + 1)) + lowerBound for inclusive integers. Most programming languages and spreadsheet tools also provide built-in functions to do this directly.

VB.NET

---

' Initialize the random-number generator. Randomize() ' Generate random value between 1 and 6. Dim value As Integer = CInt(Int((6 * Rnd()) + 1))

messagebox.show(value.tostring())

The Rnd function returns a value less than 1, but greater than or equal to zero. Before calling Rnd, use the Randomize statement without an argument to initialize the random-number generator with a seed based on the system timer.
