UDF命名单元格

Question

I'm trying to build a UDF function to name cells in a spreadsheet.

I've tried the following, but it doesn't work:

Function NameThatCell(TheCell As Range, TheName As String)
    TheCell.Name=TheName
End Function

You may want to spend some time learning about the difference between a function and a subroutine.

A function returns a value. A function has one or more inputs, then performs a calculation and returns the result of the calculation to the calling instance. That can be a worksheet formula or a call within a VBA routine. A function should never be used to manipulate elements of the worksheet like cells, range names, objects, etc.

A sub (subroutine) can do all kinds of things to elements of the worksheet. It starts, it does things, then it ends. It does not return anything and it can work with all aspects of the workbook. It can even call a function if it needs to get the result of a calculation that is performed in the function.
