Excel cell from which a Function is called [duplicate]

This question already has an answer here: How to get address of cell which calls a VBA Functions in a Excel sheet (1 answer) Closed 7 years ago.

How can I get the cell where my VBA Function is called from?开发者_如何学编程

In other words, what is the VBA equivalent for INDIRECT(ROW(), COLUMN()) ?

I'm not looking for ActiveCell.

What I want to do is have a simple function ThisRow_Col(rColumn As String) return the column X of the row it's called from. Say in B2 I call =ThisRow_Col("A"), it should return the value of A2. This should work regardless of which cell active.

EDIT: Thanks Charles for the answer: Application.Caller. The following code gets the column X of the current row, independent of where the selection is:

Function ThisRow_Col(rColumn As Range)
    ' Return INDIRECT(rcolumn & ROW())

    ThisRow_Col = Application.Caller.Worksheet.Cells(Application.Caller.Row, rColumn.Column).Value

End Function

Note that passing the column as a Range (ThisRow_Col(A1)) is better than passing it as a string, because Excel can automatically update the formulas if you move or insert columns. Of course the 1 row of A1 is just a convention.

Application.Caller returns the range object that the UDF is called from.
