Excel automation with .NET 1.1

I tried following the code below from the microsoft article Q306022 to
copy an array of data to excel in a single call. I only have a single
dimension in my array.

The problem I have is that even though the call:
oSheet.Range("A 2").Resize(1 00, 3).Value = DataArray

works it only copies the first item from my DataArray. It copies this
value to each item in the defined range in Excel. It's as if excel
does not recognize that I'm sending an array and instead sets each
element to a single value.

My actual call is:
oXLWS.Range("A1 ").Resize(nValu es.GetUpperBoun d(0) + 1, 1).Value =
nValues

I've also tried:
oXLWS.Range("A1 :A10").Value = nValues

but I get the same result.

Any ideas????

Next

'Add headers to the worksheet on row 1.
oSheet = oBook.Worksheet s(1)
oSheet.Range("A 1").Value = "Order ID"
oSheet.Range("B 1").Value = "Amount"
oSheet.Range("C 1").Value = "Tax"

'Transfer the array to the worksheet starting at cell A2.
oSheet.Range("A 2").Resize(1 00, 3).Value = DataArray

'Save the Workbook and quit Excel.
oBook.SaveAs(sS ampleFolder & "Book2.xls" )
oSheet = Nothing
oBook = Nothing
oExcel.Quit()
oExcel = Nothing
GC.Collect()

Microsoft support helped me resolve this issue. The key point is that
you must provide a two dimensional array even if you only want to fill
a single column of values in Excel.

Dim nValues(9, 0) as Integer
instead of
Dim nValues(9) as Integer

Hi there, I'm having pain with the VB behind an Access form. The form is used to create reports in Excel based on the details entered in the form. This has always worked without error on my machine (NT4, Access 2k), however as soon as I attempt to create anything on another machine (NT4, Access 2k) which most users will be working from, I receive an automation error. The problem line with the code is:

I am running: Win XP SP2 Excel 2002, Access 2002 (Office XP SP3) Using Visual Basic (not VB.NET) At one point (prior to XP SP2?!? - I can't pin it down), this did not happen and I was easily able to destroy instances of excel (with the exact same code). I have read many, many posts, and they seem to get bogged down in specifics. So I cribbed this program from the automation help file, simplified it further, so hopefully someone can

This most likely belongs in another forum but I thought I'd start here. I have a COM Object written in VB6.

The folder the DLL is trying to write to has full permissions assigned...

I have VB.Net code that opens Excel files and imports data from them. It works fine for all versions up to 2003 and has for over a year. We have users updating to Office 2003 and the Excel automation breaks on those machines. Does coding to the earliest supported version of Excel not apply once you get to 2003?
