When you have a large array, how can you quickly dump it to an Excel range? Thus far, I am using something like:

Sheet.Range("A1", "BC2000").Value = xmatrix

Open in new window

But I need to dynamically determine the "BC2000" based on the upper bounds of the array. How can this be done?

Use Resize with the dimensions of the array to get a range that matches the size of the array.

My array is xarray(,) and the following was required in order to successfully fill the range using autosizing. Thus, resize was not enough:

            Dim oXL As Excel.Application
            oXL = CreateObject("Excel.Application")
            oXL.Visible = True
            Dim oWB As Excel.Workbook
            Dim oSheet As Excel.Worksheet

            ' Get a new workbook.
            oWB = oXL.Workbooks.Add
            oSheet = oWB.ActiveSheet
            oSheet.Name = "mytest"

            Dim Rng As Excel.Range
            Rng = oSheet.Range("A1", Reflection.Missing.Value)
            Rng = Rng.Resize(xarray.GetLength(0), xarray.GetLength(1))
            Rng.Value = xarray

Open in new window

I don't quite see why Resize wasn't enough.

You've used it with the dimensions of the array to get the correct range.

Apologies, I assumed that you just needed a pointer because you only posted one line of code which I assumed was part of a larger block of code.

It would be more helpful for expert to provide all code necessary for solving an issue, and not to give pointers that cause users to continue to look for solutions. I think users are not seeking coaching, rather explicit detailed solutions.
