.net - How to tell if Excel Application is in cell-edit mode?

Question

I'm writing an Excel Addin using COM Interop from .net. I have a command that pops up a dialog, and from the dialog I do some work like collecting data from the used range of several sheets. The problem is that if a cell is in edit mode, some of the calls that I need to make will throw exceptions. I would like a way of determining before-hand that Excel is in edit mode, so that I can warn the user to finish editing the cell first.

Any ideas?

There is an Application.Ready property that is supposed to give you this information but in practice it doesn't work reliably. See here for a hackaround.

You might also want to look at setting Application.Interactive=false while your .net code is doing its stuff.
