Hello,

I want to write a simple .NET Windows app that will open an Excel workbook,
then open all workbooks that are linked to that workbook. How can I do this?
I haven't yet found documentation or samples on this.

Also, if anyone knows how to get the number of linked workbooks, that would
be very helpful too, so I can display a progress bar.

My source code so far is below. It works but is obviously missing the code
to open all linked workbooks.

Thank you so much!

Eric
