I want to make vba vlookup change event with array and dictionary so that the process becomes fast because the record data is twenty-five thousand. Sheet "master" is the data source sheet and I mark the yellow color of the result that appears in the transaction sheet ("TRANS") and the sheet "trans" is the transaction sheet and which I mark the yellow color comes from the data source of the sheet "MASTER" My green marking is key or unique id. if I use the formula "vlookup" very slowly So I want a vba code with dictionary & array?
Private Sub Worksheet_Change(ByVal Target As Range)
'On Error GoTo bm_Safe_Exit
If Intersect(Target, Range("L:L")) Is Nothing Then Exit Sub
Application.EnableEvents = False
Dim fnd As Range
Set fnd = Sheets("MASTER").Range("B:B").Find(Target, LookIn:=xlValues, lookat:=xlWhole)
If Not fnd Is Nothing Then
Target.Offset(, 2).Resize(, 1).Value = Array(fnd.Offset(, 3))
Target.Offset(, 4).Resize(, 1).Value = Array(fnd.Offset(, 6))
Target.Offset(, 6).Resize(, 1).Value = Array(fnd.Offset(, 8))
Target.Offset(, 7).Resize(, 1).Value = Array(fnd.Offset(, 4))
End If
'bm_Safe_Exit:
Application.EnableEvents = True
End Sub
This will be faster:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range, c As Range, m, wsM As Worksheet, arr
Set rng = Application.Intersect(Target, Me.Range("L:L"))
If rng Is Nothing Then Exit Sub
Set wsM = ThisWorkbook.Worksheets("MASTER")
On Error GoTo bm_Safe_Exit
Application.EnableEvents = False
For Each c In rng.Cells 'process all changed cells in ColB
m = Application.Match(c.Value, wsM.Range("B:B"), 0) 'match much faster than Find()
If Not IsError(m) Then
arr = wsM.Cells(m, "E").Resize(1, 6) 'one read
c.Offset(0, 2).Value = arr(1, 1)
c.Offset(0, 4).Value = arr(1, 4)
c.Offset(0, 6).Resize(1, 2).Value = Array(arr(1, 6), arr(1, 2))
End If
Next c
bm_Safe_Exit:
Application.EnableEvents = True 'be sure to re-enable events
End Sub
