Hi,

I use Range.SpecialCells method (C#, Excel 2003) to filter visible cells. It
works fine, but if cursor is in Formula Bar it rises an exception
"System.Runtime.InteropServices.COMException (0x800A03EC): SpecialCells
method of Range class failed".
Can I force Range.SpecialCells to work in this situation? Or can I, at
least, determine that cursor is in Formula Bar?

In some cases (including described above) Excel's Visual Basic Editor
becomes disabled. It seems, it was made intentionally to prevent Excel
automation. Can anybody explain this situation? And how can I treat it in C#.

Thank you in advance!
Sergei.
