[Help] Lottery Number Picker

[charlie6696]

I wanted to make a lottery number picker, i have it working except for the fact that you can't have two of the same numbers in you pick, so can anyone tell me a way to avoid having two of the same numbers.

Try adding the numbers you are going to use to a list, then after each add check through to see if they already exist in it.

Dim numbers As List(Of Integer) = New List(Of Integer)
again:
Dim mynum As Integer = 0 'next number example
 
If (numbers.Contains(mynum)) Then
 'make mynum equal something else
 GoTo again
Else
 numbers.Add(mynum)
EndIf
 
For i As Integer = 0 To numbers.Count - 1
 Console.WriteLine("Number " & i & " is " & numbers(i))
Next

how about using rand() ?

[mandai]

Yes the mynum is an example. You can make it equal Random.Next(x, y) and you should get your expected results.

Well also you will have to put in your loop and make it finish after the maximum number of numbers per entry etc but this is just to show how to add numbers to a list then check if one matches whats already in it.

I approved your file.

Ok I just got a look at your source and my main question is why so many switch case options? I almost wonder if its worth making a program just to generate those sequences of code.

And whats with the (Rnd() * x) for? are you trying to set some sort of range? If so I'd recommend using Random.Next(minimum, maximum). Also can't you just use keyX.ToString() when putting the numbers in the textboxes?.

I'd make this in 2 mins but I have no idea what your minimum/maximum ranges are.

I don't know what I'm talking about but don't you mean something like this:

dim lotterynumber1 as byte
dim lotterynumber2 as byte
'.
'.
'.

if lotterynumber2 = lotterynumber1 then 'Means if lotterynumber2 is the same as lotterynumber1 the program rolls lotterynumber2 again?
lotterynumber2 = random.next(x, y)
else
end if

or something like this just with every combination of those numbers? xD
