Hi,

In my Windows service,I have exported the data from database into excel using Interop Excel.
An exception is thrown when i try to save the exported excel using SaveAs or SaveCopyAs.

The exception says: Exception from HRESULT: 0x800A03EC

I have used the following code:

C#

string filename;
filename ="C://Test.test.xlsx";
excelWorkbook.SaveCopyAs(filename);

Is there any issue if COM objects are used in Windows Service??

Thanks

Make sure you have write permissions to the appropriate folder.

Make sure the file you want to override is not opened in excel (or any other application). And (Abhinav mentioned it) have a look on your permissions. And make sure you reference the correct office version in your project (a mistake that gave me the same error...) - only if you have multiple office versions installed.

Try this way:

string filename = Environment.CurrentDirectory + "\\test.xlsx";
excelWorkbook.SaveCopyAs(filename);
