variant in vba

Hi,

I am fetching the last row and storing that in an integer. For example, if my last row is 10 I want to create a two dimensional matrix with  values in the range  A1:D(lastRow) . The values in the range will be stored and then I will loop through each row and apply a function to it. How do I code for this?

Thanks

Just do

Dim DataRange As Variant

And you can put anything you like in it, no matter the source dimensions.

So


DataRange = Range("A1:D" & Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row)
0

I'm assuming this is what you are looking for..

Sub checkrange()
    Dim cell As Range, rng As Range
    Dim lrow As Long

    lrow = Cells(Cells.Rows.Count, "A").End(xlUp).Row

    Set rng = Range("A1:A" & lrow)

    For Each cell In rng

        ' Your code here now since you can read each value by reading cell.value
        'to read column B value it will be cell.offset(0,1).value and for c replce 1 by 2 and so on

    Next cell
End Sub

Hi

This will get the last row and create a two-dimensional matrix with  values of that range and you can  loop through each row and change it. Here I am appending 99

Sub StoreMatrix()
    Dim MyArray, aSheet As Worksheet, rCnt As Long, cCnt As Integer
    Dim ValueChangedArray, ArrayValue As Variant, ChangedValue As Variant
     
    Set aSheet = ActiveSheet
    Set Rng = sh.Range(sh.Range("A1"), sh.Range("D" & Cells.Rows.Count).End(xlUp))
    With ActiveSheet.Range(Rng)
   
    ReDim MyArray(1 To .Rows.Count, 1 To .Columns.Count)
    ReDim ValueChangedArray(1 To .Rows.Count, 1 To .Columns.Count)
    MyArray = Sheet1.Range(Rng).Value
       
    For rCnt = 1 To .Rows.Count

        For cCnt = 1 To .Columns.Count
       
            Debug.Print MyArray(rCnt, cCnt)
           ArrayValue = MyArray(rCnt, cCnt)
           ChangedValue = ArrayValue & 99
            ValueChangedArray(rCnt, cCnt) = ChangedValue
            Debug.Print ValueChangedArray(rCnt, cCnt)
    Next: Next
   
        End With
 


End Sub
