Una matriz con 2 dimensiones, donde el número de columnas son fijos y el número de filas son dinámicos, se puede crear como este:
Sub test2DimArray()
Dim Arr2D() As String
Dim NumberOfCol As Long
Dim I As Long, J As Long, x As Long
Dim tmpValue As String, tmpValue2 As String, tmpValue3 As String
NumberOfCol = 3
J = 1
Debug.Print "Run " & Now()
Debug.Print "Sheet content"
Debug.Print "Row col1 col2 col3"
For I = 1 To 10
tmpValue = Cells(I, 1).Value
tmpValue2 = Cells(I, 2).Value
tmpValue3 = Cells(I, 3).Value
Debug.Print I & " = " & tmpValue & " " & tmpValue2 & " " & tmpValue3
If Len(tmpValue) > 0 Then
ReDim Preserve Arr2D(NumberOfCol, 1 To J)
Arr2D(1, J) = tmpValue
Arr2D(2, J) = tmpValue2
Arr2D(3, J) = tmpValue3
J = J + 1
End If
Next
'check array values
Debug.Print vbLf; "arr2d content"
Debug.Print "Row col1 col2 col3"
For x = LBound(Arr2D, 2) To UBound(Arr2D, 2)
Debug.Print x & " = " & Arr2D(1, x) & " " & Arr2D(2, x) & " " & Arr2D(3, x)
Next
Debug.Print "========================="
End Sub
TempValue leer a partir de células A1: A10, si hay un valor de la celda Axe, redimirá la matriz con +1, y agregará Tempvalue a la matriz col1, agregará contenidos en Bx a la matriz col2 y contenidos en Cx a la matriz col3. Si la longitud del valor Ax es 0, no agrega nada a la matriz.
Debug.print muestra los resultados en la "ventana inmediata" en el editor de VB.
sin las líneas de prueba, y la adición de una técnica de gama dinámica el código puede ser:
Sub my2DimArray()
Dim Arr2D() As String
Dim NumberOfCol As Long, NumberOfRow As Long
Dim FirstCol As Long, FirstRow As Long, LastCol As Long, LastRow As Long
Dim I As Long, J As Long, X As Long
Dim tmpValue As String, tmpValue2 As String, tmpValue3 As String
'if cells with values start in A1
With ActiveSheet.UsedRange
NumberOfCol = .Columns.Count
NumberOfRow = .Rows.Count
End With
'if cells with values starts elsewhere
With ActiveSheet.UsedRange
FirstCol = .Column
FirstRow = .Row
LastCol = .Column + .Columns.Count - 1
LastRow = .Row + .Rows.Count - 1
End With
J = 1
For I = 1 To NumberOfRow 'or For I = FirstRow to LastRow
tmpValue = Cells(I, 1).Value 'or tmpValue = Cells(I, FirstCol).Value
If Len(tmpValue) > 0 Then
ReDim Preserve Arr2D(NumberOfCol, 1 To J)
For X = 1 To NumberOfCol 'or For X = FirstCol to LastCol
Arr2D(X, J) = Cells(I, X).Value
Next X
J = J + 1
End If
Next I
End Sub
-1: Dos ciclos anidados para cada redim de una matriz - no es una idea brillante en todo! ¿Qué va a pasar si tienes una matriz de 10 000 elementos? –
