Hello all. I need to know if there is any way to this. I am using VS/
C# and COM interop to develop an Add-in for Excel.

I have a thread that tries to write on some cells of the current
spreadsheet. The problem is that when Excel is busy, these call return
an exception.


class MyClass {

Excel.Range cell;

public MyClass(Excel.Range cell) { this.cell = cell; }

// This method is called from a different thread than the original one
where the add-in starts
void AsynchronousWrite(object stuff)
{
cell.Value2 = stuff;
}
}

That throws the following exception when Excel is busy (for example
when the user is editing the content of a cell):

System.Runtime.InteropServices.COMException (0x800A03EC): Exception
from HRESULT: 0x800A03EC

Is there any straightforward way to solve this problem?

Thank you for your help.
