I have created a class library which has user defined functions for excel.
One of functions need reference to current excel so as to insert value to many cell. I have given the code below showing how i am getting active worksheet.
The problem occurs when i am trying to put value in to cell or range.
//Code
Excel.Applicati on oXL = null;
oXL = (Excel.Applicat ion)
System.Runtime. InteropServices .Marshal.GetAct iveObject("Exce l.Application") ;
oXL.Visible = true;
Excel.Worksheet sh = (Excel.Workshee t)oXL.ActiveShe et;
Excel.Range rng = (Excel.Range)oX L.ActiveCell;
//The following line gives me the error
sh.Cells[1,1]="Test";
I am not able set value to any cell or range.
Please Help,

Additional information: Exception from HRESULT: 0x800A03EC.
This code produced this error. I am pretty sure I got this to run a while
back and I was wondering if you all see anything I am doing wrong.....or do
you have a suggestion for a better way.......I do know this method is quite
slow.

After sorting a dataset using a DataView and then creating a DataRowView I
get an Exception from HRESULT: 0x800A03EC on only one field in the
DataRowView.
code snippet:
xlWS.Cells(row, 1).Value = drvProd("RunNo")
xlWS.Cells(row, 2).Value = drvProd("CGN")
xlWS.Cells(row, 3).Value = ""
xlWS.Cells(row, 4).Value = drvProd("WorkOrder")

I am communicating with Excel Interop dll using c#. The get_Range
function throws an exception if the parameters are invalid. For e.g.
get_Range("Mikil", Type.Missing); will crash if the "Mikil" named range
is not present.
Why the does the function crash instead of returning "null"?
