Use Cell Value Reference in VBA to determine range - vba

Question

I know this is a pretty basic question, but im still working on building my VBA skills. I am in a predicament where I have made a mapping system of various reports I receive that get placed in a compiled workbook. These reports have entirely different formats etc. I have a copy/paste macro that copies columns and places them in their correct position on the compiled workbook.
I've come into situations however where there are a lot of duplicate / empty rows that screw up my Macro. I have used two VBA functions to solve this, one is a "delete row if reference column is blank":
Sub DeleteBlankARows()
With Application
.Calculation = xlCalculationManual
.ScreenUpdating = False
Dim r As Long
For r = Cells(Rows.Count, 6).End(xlUp).Row To 1 Step -1
If Cells(r, 6) = "" Then Rows(r).Delete
Next r
.Calculation = xlCalculationAutomatic
.ScreenUpdating = True
End With End Sub
This deletes rows where cells in column F are empty
I also use a copy/paste down macro:
Sub CopyUntilBlank()
Dim last_row As Integer
last_row = Range("f1").End(xlDown).Row
Dim rng As Range
Set rng = Range("d2:d" & last_row)
For Each cell In rng.Cells
cell.Activate
If ActiveCell.Value = "" Then
ActiveCell.Value = ActiveCell.Offset(-1, 0).Value
End If
Next cell End Sub
This copies and pastes down blank rows in column D until you hit a non-blank cell then re-does this until the range of values in column F.
These macros work well for me, but because I have multiple sheets like this, I would like to create a cell references that make the ranges dynamic. For instance: in the DeleteBlankRows macro, I would like to have the column reference in Cells(r,6) be determined off of a cell value in sheet1 - so for instance if the value in cell A1 on sheet 1 is 2 it would change the column reference to "2" (column B).
I would like the same to happen for the copy/paste down macro. I'm pretty sure this is just some reference to A1.Value but I don't know how to properly write such thing.
Thank you for your support, I've gone quite a long way with all the support of the community.

Answer 1

An example using your first sub:
Sub DeleteBlankARows(colIndex as Long)
Dim colIndex as long
colIndex = Sheet1.Range("a1").value
With Application
.Calculation = xlCalculationManual
.ScreenUpdating = False
Dim r As Long
For r = Cells(Rows.Count, colIndex).End(xlUp).Row To 1 Step -1
If Cells(r, colIndex) = "" Then Rows(r).Delete
Next r
.Calculation = xlCalculationAutomatic
.ScreenUpdating = True
End With
End Sub
It's not clear from your question which column in the second sub needs to be dynamic (or both of them?)
EDIT try this:
Sub CopyUntilBlank()
Dim last_row As Long, col1 as Long, col2 as Long
Dim rng as Range
col1 = Sheet1.Range("a2").value
col2 = Sheet1.Range("a3").value
last_row = Cells(1, col1).End(xlDown).Row
'This next line is better if there's any chance
' of blanks in this column
'last_row = Cells(Rows.Count, col1).End(xlUp).Row
With ActiveSheet
Set rng = .Range(.Cells(2, col2), .Cells(last_row, col2))
End With
For Each cell In rng.Cells
If cell.Value = "" Then
cell.Value = cell.Offset(-1, 0).Value
End If
Next cell
End Sub
