Hi,

hopefully this is the right group for posting my question.

I'm writing an automation addin for excel using vb.net. One of my
function should be able to overwrite the cell values of a range object
passed as parameter to the function. Here is a small sample of the
function header:

Public Function WriteData(ByRef ResultCells As Range) As Double

I tried the following:
ResultCells.Value2(1, 1) = 42
ResultCells.Value(1, 1) = 42
ResultCells.Cells(1, 1).FormularR1C1 = 42

None of these calls work.

Does anybody know how to overwrite values of a range object? Are there
any other ways to return multiple valus from a user-defined function?

Regards,
Sascha

Sascha,

I'm not sure of VB.NET, but in VBA functions cannot be used to write data to ranges - the code that
does it is simply ignored. Try passing the range to a public Sub instead....

Hello,

it seems to be the same in vb.net. The code compiles, throws no error,
but doesn't work either. The workaround for me is to return a
Double(,)-Array. That way I can return a matrix, but the user can not
control the order and placement of the result columns. Not nice, but
it works...
