VBA: Find last row in a fixed number of ranges - excel

Question

I tried for a few hours to search and look for a possible answer. I am about ready to give up. I haven't been able to find someone with a scenario quite like the one I am asking, maybe I overlooked it.
I want to find the last row in a specific range. The ranges are A7 to A21. I want to be able to enter input data from my form to the empty row within that range...
Here is where it gets tricky. I also have two other categories on the same sheet where I need to input data. Data may already be here, again I want to find the last row and then input data. Ranges A27:A41.
And the last category ranges A46:A66.
Hopefully someone here can help me out.

Answer 1

Define the ranges you use as tables in Excel on the sheet. Then in your code use:
Dim Table1 As listObject, Table2 As ListObject
With ThisWorkbook.Worksheets("Name of the sheet the tables are on")
Set Table1 = .ListObjects("Name of the table")
Set Table2 = .ListObjects("Name of the table")
End With
Dim LastRowT1 As Long, LastRowT2 As Long
LastRowT1 = 1: LastRowT2 = 1
Do Until Table1.DataBodyRange(LastRowT1, 1) = Empty
LastRowT1 = LastRowT1 + 1
Loop
Do Until Table2.DataBodyRange(LastRowT2, 1) = Empty
LastRowT2 = LastRowT2 + 1
Loop
'If you run out of space and automatically want to add an extra row add
'the following code.
If LastRowT1 > Table1.ListRows.Count Then
Table2.ListRows.Add AlwaysInsert:=True
End If
If LastRowT2 > Table2.ListRows.Count Then
Table2.ListRows.Add AlwaysInsert:=True
End If
The Value of LastRowT1 and LastRowT2 should be the row number (of the listobject) of the first empty row.

This should get you pointed in the right direction...
Sub Main()
Dim r1 As Range
Dim r2 As Range
Dim r3 As Range
Dim rFind As Range
'Set your range vars
Set r1 = Range("A7:A21")
Set r2 = Range("A27:A41")
Set r3 = Range("A46:A66")
'Find the next empty cell and display the address
On Error Resume Next
'First range
Set rFind = r1.Find("*", searchdirection:=xlPrevious).Offset(1, 0)
If Not rFind Is Nothing Then
MsgBox "First open cell in " & r1.Address & " is " & rFind.Address
Else
MsgBox "First open cell in " & r1.Address & " is " & r1.Cells(1, 1).Address
End If
'Second range
Set rFind = r2.Find("*", searchdirection:=xlPrevious).Offset(1, 0)
If Not rFind Is Nothing Then
MsgBox "First open cell in " & r2.Address & " is " & rFind.Address
Else
MsgBox "First open cell in " & r2.Address & " is " & r2.Cells(1, 1).Address
End If
'Third range
Set rFind = r3.Find("*", searchdirection:=xlPrevious).Offset(1, 0)
If Not rFind Is Nothing Then
MsgBox "First open cell in " & r3.Address & " is " & rFind.Address
Else
MsgBox "First open cell in " & r3.Address & " is " & r3.Cells(1, 1).Address
End If
End Sub
This assumes that you're filling the cells from the top down (e.g. A7 fills first, A8 is next, then A9, etc.). If that's not the case, then instead of .Find you'd need to use a loop. You'll definitely need to adapt this to you situation, especially the logic for when all the cells in your ranges fill up.

To make your request more generic (and hence scalable), you could create a function to find the first available row of any given range:
Function FindFirstOpenCell(ByVal R As Range) As Integer
Dim row, col As Integer
row = R.row
col = R.Column
FindFirstOpenCell = Cells(row + R.Rows.Count - 1, col).End(xlUp).row + 1
End Function
From here you could simply call the function over and over:
Dim row As Integer
row = FindFirstOpenCell(Range("A7:A21"))
Cells(row, 1).Value = "My Next Item"
