Understanding Retrieving and Storing VBA Values in an Array

Asked 2 years ago, Updated 2 years ago, 333 views

The following code is used to store cell values in an array, but when I checked Debug.Printary(j,1), it seems that the values are not displayed (not retrieved).

ary=Array (Cells(j, "E").Value, Cells(j, "F").Value, Cells(j, "G").Value, Cells(j, "H").Value, Cells(j, "I").Value)

What is wrong with the code below?There are no errors.

 Dim j As Long
Primary As Variant

For j=1 To LastRow
    If Cells(j, "J").Value="JST" Then
        aary=Array (Cells(j, "E").Value, Cells(j, "F").Value, Cells(j, "G").Value, Cells(j, "H").Value, Cells(j, "I").Value)
        Debug.Printary(j,1)
    End If
Next

What is wrong with the code below?There are no errors.

Debug.Printary(j,1) should get an "Index Not in Valid Range" error.
OnError Resume NextIs there a code somewhere that ignores this error?If so, let's comment it out first.

The reason for the error is that the Array function returns a one-dimensional array, so aary is a one-dimensional array.
Nevertheless, we treat it as a two-dimensional array with ary(j,1), which results in the above error.

Debug.Printary(0)
displays the first value of the array (=Cells(j, "E").Value).

If you want to put the first row of columns E through I into an array, you can do it in one row below without looping.

Dim LastRow As Long
   LastRow=Cells(Rows.Count, "E").End(xlUp).Row

   Primary() As Variant
   aary=Range(Cells(1, "E"), Cells(LastRow, "I")).Value

   US>'Check the first column (column E) value of the array
   Dimi
   Fori=1 to LastRow
       Debug.Printary(i,1)
   Next

By the way, the array substituted with Value as shown above starts with an index of 1.
The Array function starts with 0.
