[RESOLVED] Random Number

[StudNewf]

Im making a number game and to do it I need the form to spit out any number between 1 and 100. I was able to make it spit out 70, but everytime the form loads, its always 70. Can someone show me a way to do it so that its a different number every time I start the form?
Thanks

Use Randomize

Dim iValue As Integer
    Randomize
    iValue = Int((100 * Rnd) + 1)

Does it have to be Integer or can it be Double? Whats the difference?

It can be double too, but then what exactly do you want it to do. Are you trying to generate random numbers between 1 to 100 with decimal places. If that is the case then you can use

Dim iValue As Double
Randomize
iValue = (100 * Rnd) + 1

Public Function RandomRange(ByVal RangeStart As Int32, ByVal RangeEnd As Int32) As Int32
Return New System.Random().Next(RangeStart, RangeEnd+1)
End Function

I converted it form C# in my head so hopefully it's right

Oh is it VB.NET.

Till now I have been thinking it is VB 6.0. In .NET it is simple

Dim rndNumber As New Random
        MessageBox.Show(rndNumber.Next(1, 100).ToString)

Ignore my previous two posts. I was under impression that this thread was posted in Classic VB forum. Sorry about that.

In .NET 2005 it can be done like this

label.text = CStr(Int(Rnd() *100))

That isn't a vb05 feature, it is legacy... comes from vb6, still supported in all version of .net thus far.

the .net way is the above post, using the Random class.

Sorry, Never used VB6.. Just stating a way that I know is possible in VB 2005.
