AdvancedFilter CopyToRange:= First empty row - vba

Question

I am trying to use AdvancedFilter in VBA, but instead of setting copy to range to a fixed value I want to copy it to the first empty row.
I am trying to append two tables from two separate AdvancedFilter steps, is there an easier way? E.g. first copy the two tables to separate location and then merge them? Both table have the same columns.
My code as of now is:
Set rngCriteria_v = Sheets("1").Range("filter")
Set rngExtract_v = Sheets("2").Range("**Here first empty row**")
Set rngData_v = Sheets("3").Range("Input")
rngData_v.AdvancedFilter Action:=xlFilterCopy, _
CriteriaRange:=rngCriteria_v, _
CopyToRange:=Sheets("Stocks_5_control").Columns("AG").Find(vbNullString, Cells(Rows.Count, "AG")), _
Unique:=False

Answer 1

Change your advanced filter line to this:
rngData_v.AdvancedFilter xlFilterCopy, rngCriteria_v, Sheets("Stocks_5_control").Cells(Sheets("Stocks_5_control").Rows.Count, "AG").End(xlUp)(2)

The following merges the all the worksheets in to a new sheet called Master. Hope that helps :)
Dim wrk As Workbook 'Workbook object - Always good to work with object variables
Dim sht As Worksheet 'Object for handling worksheets in loop
Dim trg As Worksheet 'Master Worksheet
Dim rng As Range 'Range object
Dim colCount As Integer 'Column count in tables in the worksheets
Dim wd As Object 'used for word document
Dim WDoc As Object
Dim strWorkbookName As String
Set wrk = ActiveWorkbook 'Working in active workbook
For Each sht In wrk.Worksheets
If sht.Name = "Master" Then
MsgBox "There is a worksheet called as 'Master'." & vbCrLf & _
"Please remove or rename this worksheet since 'Master' would be" & _
"the name of the result worksheet of this process.", vbOKOnly + vbExclamation, "Error"
Exit Sub
End If
Next sht
'Add new worksheet as the last worksheet
Set trg = wrk.Worksheets.Add(After:=wrk.Worksheets(wrk.Worksheets.Count))
'Rename the new worksheet
trg.Name = "Master"
'Get column headers from the first worksheet
'Column count first
Set sht = wrk.Worksheets(1)
colCount = sht.Cells(1, 255).End(xlToLeft).Column
'Now retrieve headers, no copy&paste needed
With trg.Cells(1, 1).Resize(1, colCount)
.Value = sht.Cells(1, 1).Resize(1, colCount).Value
'Set font as bold
.Font.Bold = True
End With
'We can start loop
For Each sht In wrk.Worksheets
'If worksheet in loop is the last one, stop execution (it is Master worksheet)
If sht.Index = wrk.Worksheets.Count Then
Exit For
End If
'Data range in worksheet - starts from second row as first rows are the header rows in all worksheets
Set rng = sht.Range(sht.Cells(2, 1), sht.Cells(65536, 1).End(xlUp).Resize(, colCount))
'Put data into the Master worksheet
trg.Cells(65536, 1).End(xlUp).Offset(1).Resize(rng.Rows.Count, rng.Columns.Count).Value = rng.Value
Next sht
'Fit the columns in Master worksheet
trg.Columns.AutoFit
