I have an Excel add-in firing an HRESULT 0x800401A8 error, when calling the getter of Worksheet.Parent.

I would be glad if anyone could let me know what the error might be, but more importantly and more generally, I would like to know how I can understand these HResult codes?

I did the following but am still confused:

Read the Microsoft's documentation on the Structure of COM error Codes.
Checked this SO thread.
Tried my chances with Magnum DB.

Thanks!
