Primes Numbers

[na00007]

Hallo
I have a problem. I want to make a program in Visual Basic 2005. It should find and print prime numbers. I do not know how to make it. Can someone helps me.

Thanks

Hi. Can you tell us please if your difficulty is in programming or in working out an algorithm to generate prime numbers?

BTW you may get a more accurate answer in the .NET forum as you are using vb.NET.

hi
don't know about 2005, but in VB6 you may use this example:
create a form with a listbox (List1)

 
Private Sub Form_Load()
Dim prime As New Collection
prime.Add 1                         'actually 1 is a special number
prime.Add 2                         '2 is the first real prime
For i = 3 To 1000                   'start searching from 3 to whatever number (1000)
NoPrime = False                     'assume primenumber
    For dev = 2 To prime.Count - 1  'try to devide actuale number by all other primes
    If i Mod prime(dev) = 0 Then    'if devision has no remains then no prime
       NoPrime = True
       Exit For
    End If
    Next dev                        'if i is a prime, add to collection
    If NoPrime = False Then prime.Add i
Next i
 
For i = 1 To prime.Count - 1        'if all are done, put into the list
List1.AddItem prime(i)
Next i
 
End Sub

I know the algorithm but I have problem in programming
