looping to assign an array [RESOLVED]

I have an array array(2) that will store 3 values. - 0,1, and 2 (that IS right, i think)

I need to assign array(0) a value that is returned by an indexof() function and repeat this two more times.

how can I make the index number increase by one when assigning the array?

array(0) = first occurance
array(1) = 2nd
array(2) - 3rd

Any suggestions?

Note : VB.NET , C#.NET arrays are zero-based . Meaning the first element is 0 , next is 1 . You can iterate through the array by assigning the index property of the array to get the specific element .


Example :
All elements in the array are initialized with zero . Note how it adds 1 to each element .

VB Code:

Private Sub anotherTest()
        Dim myar(2) As String
 
        For i As Integer = 0 To 2
            'Here you can assign whatever to your array elemnts
            'Like this 
            myar(i) += i
            MessageBox.Show(myar(i))
        Next
    End Sub

what I tried was close. I had the the syntax a bit wrong! I am starting to get this@!!@:blush:

Do you mean adding elements to the array after its declared? In other words changing it from 3 elements to 4 and so on. If that is what you mean than you can't declare it a fixed size at the begining but its easier to just use an ArrayList object instead. Otherwise if you are just talking about assigning values to existing elements then Pirates code should work fine.

right. I know all I need is 3 so I am going to assign 0,1 and 2 unknown values. Pirate's been a BIG help lately.:wave:

Pirate's the bomb!

great. I got my array to get the needed info. What I'm thinking now is to make this code into a function. More code will take the integers that the array is assigned and extract strings out of another string. Can I return more than one thing from a function?

ie:

return strArtist, strAlbum, strTrackNum
(is that even how to do it?)

Here is what I have so far if anyone cares to peruse it:

Code:

---

Public Function FindDashes(ByVal str) As Integer

        'declare the variables first
        Dim start, at, [end], count, myar(3), i As Integer

        'initialize the variables
        [end] = str.Length
        start = 3
        count = 0
        at = 0
        i = 0

        'go through the string and find and mark all the dashes
        While start <= [end] AndAlso at > -1 ' start+count must be a position within -str-.
            count = [end] - start
            at = str.IndexOf("-", start, count)
            myar(i) = at

            If at = -1 Then
                Exit While
            End If

            'erase this, it's just for debugging
            Console.WriteLine("{0}", at)
            Console.WriteLine("myar(" & i & ") = " & myar(i))

            i = i + 1
            start = at + 1
        End While
        Return strArtist, strAlbum, strTrackNum

    End Function

keeping in mind that the code to get the string info hasn't been added yet.

No , you can't return more than one value at a time . This can be done in C#:D , but alternatively , use ArrayList or string array to return the extracted strings that you mentioned . For the rest , I'm not sure what you mean exactly .
