Data structure which needs to be filled in VBA

问题:

I need to load some data from an 2D array to an type array structure.

My type structure looks like the following:

Public Type LocationType
  LocationID As String
  Description As String
  ZoneID As String
  IsEmpty As Boolean
  LastPalletArrivedTime As Date
  PalletID As String
  Sequence As Long
End Type

I declared the following:

Dim LocationArray() As LocationType

which needs to be filled with data from a 2D array.

The code I use to fill LocationArray is as follows:

For x = 1 To UBound(TextFileLine())
    LocationArray(x).Description = SplitTextLines(x, 0)
    LocationArray(x).LocationID = SplitTextLines(x, 1)
    LocationArray(x).Sequence = SplitTextLines(x, 2)
    LocationArray(x).ZoneID = SplitTextLines(x, 3)
    LocationArray(x).PalletID = SplitTextLines(x, 4)
    LocationArray(x).LastPalletArrivedTime = SplitTextLines(x, 5)
    LocationArray(x).IsEmpty = SplitTextLines(x, 6)
Next x

I was wondering if there is any method or code I could use to make the code which I use to fill "LocationArray" easier?

*Note all my variables are declared and code is working. I am just asking for better or easier method to the one I am currently using. Help will be much appreciated.

After some thinking

create a Class module and name it Location

this is the code to use in the class module

Option Explicit

Public LocationID As String
Public Description As String
Public ZoneID As String
Public IsntEmpty As Boolean
Public LastPalletArrivedTime As Date
Public PalletID As String
Public Sequence As Long

Public Property Let Item(index As Long, value As Variant)
    Select Case index
        Case 1
             LocationID = value
        Case 2
             Description = value
        Case 3
             ZoneID = value
        Case 4
             IsntEmpty = value
        Case 5
             LastPalletArrivedTime = value
        Case 6
             PalletID = value
        Case 7
             Sequence = value
    End Select
End Property

Public Property Get Item(index As Long) As Variant
    Select Case index
        Case 1
             Item = LocationID
        Case 2
             Item = Description
        Case 3
             Item = ZoneID
        Case 4
             Item = IsntEmpty
        Case 5
             Item = LastPalletArrivedTime
        Case 6
             Item = PalletID
        Case 7
             Item = Sequence
    End Select
End Property

this is a standard Module1 for testing (note the commented section)

Option Explicit

Sub Main()

    Dim myLoc As Location
    Set myLoc = New Location

    Dim i As Long

    '////////////////
    ' SAMPLE filling

    For i = 1 To 7

        ' covering BOOLEAN
        If i = 4 Then
            myLoc.Item(i) = False

        ' covering DATE
        ElseIf i = 5 Then
            myLoc.Item(i) = Now

        ' covering LONG
        ElseIf i = 7 Then
            myLoc.Item(i) = i

        ' convering STRING
        Else
            myLoc.Item(i) = CStr("property " & i)

        End If
    Next i

   '///////////
   ' PRINTING

    For i = 1 To 7
        Debug.Print "property:" & i, myLoc.Item(i)
    Next i

    '/////////////////
    ' pay attention
    ' this is what you could do

    ' this section is commented as Im unable to test it
    ' but this should work for you


'    create a collection

'    Dim c As Collection
'    Set c = New Collection
'
'    Dim x As Long
'    For x = 1 To UBound(TextFileLine())
'        Dim loc As Location
'        Set loc = New Location
'
'        For i = 1 To 7
'            loc.Item(i) = SplitTextLines(x, i - 1)
'        Next i
'
'        c.Add loc
'    Next x
'
'    ' now if you wanted to retrieve the data
'    ' you iterate over the collection
'
'    For i = 1 To c.Count
'        For j = 1 To 7
'            Debug.Print c.Item(i).Item(j)
'        Next j
'    Next c


End Sub
