Answer 1

I assume you mean opened by a particular instance of Excel. You will generally have a reference to an Excel.Application object, either implicitly (eg if your app is Excel VBA or VSTO VB.NET) or because you have explicitly created an instance.

You can then iterate through the Application.Workbooks collection, looking for an instance that matches the file you're interested in, for example, by comparing the Workbook.Path property.

Note that in Excel, you can't open two workbooks with the same filename (but different directories) simultaneously. So if you find a workbook with the same name as your file, but a different directory, you'll have to close it before opening your workbook.
