VBA - Build an Array by Looping Through Another Array with Specific Criteria

0 votes

When it comes to the programming, I'm not sure where to begin. I have an Excel column of data with an array that is dispersed with non-consecutive zeros. I want to create a new column of data and choose the digit that comes before the zeros. A sample data set is provided below (I'll select out 1, 4, and 6):

  5
    1
    0
    4
    0
    820
    4
    6
    0
    74
    Sub Cat()   
     
          Range("V12").Select
    
          Do Until IsEmpty(ActiveCell)
    
             ActiveCell.Offset(1, 0).Select
          Loop
       
    End Sub

Please attempt the next option. It is assumed that A contains the range that needs to be processed. A column's content will be dropped into the resulting array in B:B, starting with B1:

Sub ExtractBeforeZero()
  Dim sh As Worksheet, lastR As Long, arr, arrB0, i As Long, k As Long
  
  Set sh = ActiveSheet
  lastR = sh.Range("A" & sh.rows.count).End(xlUp).row
  
  arr = sh.Range("A1:A" & lastR).Value2 'place the range in an array for faster  processing
  ReDim arrB0(1 To UBound(arr)) 'redim the array to keep the return of its maximum possible number of elements
  k = 1
  
  For i = 1 To UBound(arr)
        If arr(i, 1) = 0 Then arrB0(k) = arr(i - 1, 1): k = k + 1
  Next i
  
  If k > 1 Then 'if at least a zero has been found:
    ReDim Preserve arrB0(1 To k - 1) 'keep only the filled elements
    'drop the resulted array:
    sh.Range("B1").Resize(UBound(arrB0), 1).Value2 = Application.Transpose(arrB0)
  Else
     MsgBox "No zero could be found in the processed column..."
  End If
End Sub
