During development of a data management system I'm designing, I've run into a roadblock while trying to implement an exporting system to transfer datagrid information from the user's view to an Excel spreadsheet. As my company currently uses an extensive (excessive?) number of Excel spreadsheets now for daily functions, it's important I implement this ability in the new software until possible to wean everyone off the Excel Spreadsheets.

Consequently, I've run into the following error message upon execution of my exportation procedure:

"An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll
