How to move arrays 1 place down ?

[iFrolox]

Well i'll try to be clear as possible, i'm making like an account organizer (helper/tool) w.e you wanna call it, and for example i have 10 accounts.

I want to delete account #5 (They are array), what i need it to do is move account #6, 7, 8, 9 & 10 down and number 5 would be the last account (Last account will be blank).

I have this Listbox to change in between the accounts, so i can change from 1 to 10 fast, account 11 is just blank just if i want to add another account.

My codes:

I need help on the part of moving down the arrays.
I deleted account #5 so i want account#5 to be the last accounts and all accounts after 5 to move 1 place down.

Any help ? Thx.

You have alot of over head here I see.

Is using a database out of the question?

If it is, then what about using an ArrayList?

When using an array list, you can simply store each account in the ArrayList and remove one by:

Dim ar As New ArrayList
Dim index As Integer = 3
ar.RemoveAt(index) 'This will remove the fourth entry.'

This will remove the account at the fourth entry in the array.

You will need to cast to the account type when using arraylists too.

Example:

Dim refAccount as Accounts


refAccount = TryCast(ar(0),Accounts)

If refAccount IsNot Nothing Then
    'Cast was successfull. Continue working'
Else
    'Cast was unsuccessfull. Halt application or implement fault tolerance.'
End If

[iFrolox]

I've used removeat, but when I do it deletes that entry like you said, that entry stays blank, and what I want is to move that entry to the last one and then put it in blank

[Begginnerdev]

You could try something like:

Dim curItem as Integer = 3
ar.RemoveAt(3)
For i = CurItem to ar.Count - 2
    ar(i) = ar(i + 1)
Next

ar.RemoveAt(ar.Count - 1)

This will "push" everything up one, then delete the last one.

[iFrolox]

Dim ar As New ArrayList

Im not using it from a database, and for me to use removeAt i got this function.

Module RemoveUser
    <System.Runtime.CompilerServices.Extension()> _
    Function RemoveAt(Of T)(ByVal arr As T(), ByVal index As Integer) As T()
        Dim uBound = arr.GetUpperBound(0)
        Dim lBound = arr.GetLowerBound(0)
        Dim arrLen = uBound - lBound

        If index < lBound OrElse index > uBound Then
            Throw New ArgumentOutOfRangeException( _
            String.Format("Index must be from {0} to {1}.", lBound, uBound))

        Else
            'create an array 1 element less than the input array
            Dim outArr(arrLen - 1) As T
            'copy the first part of the input array
            Array.Copy(arr, 0, outArr, 0, index)
            'then copy the second part of the input array
            Array.Copy(arr, index + 1, outArr, index, uBound - index)

            Return outArr
        End If
    End Function
End Module

i used

        Dim curItem As Integer = 3
        Me.CurrentAcc.RemoveAt(Me.AccNumber.Text)
        For i = curItem To Me.CurrentAcc.Count - 2
            Me.CurrentAcc(i) = Me.CurrentAcc(i + 1)
        Next
        Me.CurrentAcc.RemoveAt(Me.CurrentAcc.Count - 1)
    End Sub

but didn't work..

Edit:

i used:

        Dim curItem As Integer = Me.AccNumber.Text

        Me.CurrentAcc.RemoveAt(Me.AccNumber.Text)

        For i = curItem - 1 To Me.CurrentAcc.Count - 2
            Me.CurrentAcc(i) = Me.CurrentAcc(i + 1)
        Next

        Me.CurrentAcc.RemoveAt(Me.CurrentAcc.Count - 1)

And it deleted it but, it justs makes it blank, at the end of my accounts theres already 1 blank accoutn that's always blank to keep adding more accounts, so when i delete account number 3 from the 5 i have i get account 5 and account 6 blank, any possible way to complete delete the last index.

[iFrolox]

Well, its kind of solved because i had #5 and #6 blank, but i forgot to update the DomainUpDown (Where i can change from accounts), but i used in a button:

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        MsgBox("How many accs: " & CurrentAcc.Count())
        MsgBox("Selected Acc: " & Me.AccNumber.SelectedIndex + 1)
    End Sub

When i load the app and i click it, it displays that i have 1 account and i have 1 item in the domainupdown, ok good, i add 3 accounts and +1 account which is the last account that is in blank to keep adding more accounts, i delete account 2 it says that i have 4 accounts, and 3 items in the domainupdown, i could leave it like this since is kind of working but the account 4 is blank and if i keep adding accounts and deleting it will keep adding more arrays not being used.

im using:

        Dim curItem As Integer = Me.AccNumber.SelectedIndex

        CurrentAcc.RemoveAt(Me.AccNumber.Text)

        For i = curItem To CurrentAcc.Count - 2
            CurrentAcc(i) = CurrentAcc(i + 1)
        Next

        CurrentAcc.RemoveAt(CurrentAcc.Count - 1)
        Me.AccNumber.Items.RemoveAt(Me.AccNumber.Items.Count - 1)

RemoveAt:

    <System.Runtime.CompilerServices.Extension()> _
    Function RemoveAt(Of T)(ByVal arr As T(), ByVal index As Integer) As T()
        Dim uBound = arr.GetUpperBound(0)
        Dim lBound = arr.GetLowerBound(0)
        Dim arrLen = uBound - lBound

        If index < lBound OrElse index > uBound Then
            Throw New ArgumentOutOfRangeException( _
            String.Format("Index must be from {0} to {1}.", lBound, uBound))

        Else
            'create an array 1 element less than the input array
            Dim outArr(arrLen - 1) As T
            'copy the first part of the input array
            Array.Copy(arr, 0, outArr, 0, index)
            'then copy the second part of the input array
            Array.Copy(arr, index + 1, outArr, index, uBound - index)

            Return outArr
        End If
    End Function

Almost done, just want to know if is posible to completely delete the array instead of just hidding it.

[Begginnerdev]

I have not tried it before, but you can make use of ReDim Preserve.

You can recreate the array every time it is needed.

Thank you, i got it working now :)
