generate random number from range

Code:

---

Dim random As New Random()
random.Next(65, 91) ' random.Next(min, max) the range is min to max -1

---

EDIT for akhileshbc : place this code in an event, the Dim random As New Random() can also be placed as a global variable (in a class and not in an event )
the code returns a random number between a minimum and a maximun in the example above a number between 65 and 91 will be returned

you can also do stuff like : (instead of the line random.Next(65, 91))

label1.text = random.Next(65, 91) ' the label will display a random number in the range 65 - 91
or
textbox1.text &= random.Next(65, 91) ' concates a random number to the textbox (added from the tool box to the form)
or
textbox1.text &= chr(random.Next(65, 91)) ' concates a random char (a - z) to the textbox

You should clarify what this code actually returns.
I'd bet most new coders would expect this to return a random number between 65 to 90 but it doesn't.

Random.Next Method (Int32, Int32)
The range of return values includes minValue but not maxValue.

the code was tested and worked on vb.net 2010

That call will never return 90, I already posted a link to the doc and the reason.
