Christopher,

I think you should take a look at Exception Handling (Try, Catch and Finally
or something like that) in VB.Net and catch the exception and deal with it
in VB.Net.

Hi, I need to conditionally rename a worksheet in an excel 2000 workbook.
I have the following piece of code:
application.excel.worksheets("SheetName").Name = "NewSheetName"

which works to rename it. However, if SheetName doesn't exist or has been
renamed the program throws and exception. How can I check to make sure
that
a sheet exists in the sheets collection?
