Ryan,
Write the code in the oldest version you intend to support.
Additional arguments in later versions are optional and if missing, take
their default values.
If this were not true, there would be no such thing as backwards
compatibility.

Hi,

I am working on some software that integrates an excel workbook. I am
having a problem calling the workbook.saveas method. I am developing on
XP with excel 2003, but i need this code to work with excel 2000.
Apparently excel 2000 requires saveas to have 10 arguments while excel
2003 requires 12 arguments. Ideally I would have something like this:

if (System.String.Compare(_app.Version,"10") < 0)
{
//Office 2000
_wb.SaveAs(_strFilename, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing,
Excel.XlSaveAsAccessMode.xlNoChange,Type.Missing, Type.Missing,
Type.Missing);
}
else
{
//Office XP
_wb.SaveAs(_strFilename, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing,
Excel.XlSaveAsAccessMode.xlNoChange,Type.Missing, Type.Missing,
Type.Missing, Type.Missing,Type.Missing);
}

However I cannot compile this on my XP machine because it says "no
overload for method saveas takes 10 arguments" at the first SaveAs
call.

Help!
