Extracting images from Excel 2007 - 2010 document
===

I am writing an application that extracts images from an Excel spreadsheet using COM interop.

It works perfectly fine if I save the file as an XLS (2003 format) from Excel 2010 however if I save it as an XLSX (2007 to 2010 format) it produces this exception "The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))"

My code is below. The exception is thrown by the line pic.Copy(); which works perfectly fine with an XLS. 

<!-- language: c# -->

        public static BitmapSource[] ImportImages(string FileName)
        {
            //Create the Excel Object
            ExcelObj = new Microsoft.Office.Interop.Excel.Application();

            //Create the Workbooks wrapper
            Workbooks workbooks = ExcelObj.Workbooks;

            //Open the Excel workbook
            Workbook workbook = workbooks.Open(FileName);

            //Reference the worksheets in the Excel file
            Sheets sheets = workbook.Worksheets;

            List<BitmapSource> images = new List<BitmapSource>();

            List<Picture> pics = new List<Picture>();

            //Reference the first sheet in the workbook
            Worksheet sheet = sheets[1];

            for (int i = 1; i < 30; i++)
            {
               pics.Add(sheet.Pictures(i));
            }

            foreach (Picture pic in pics)
            {
                pic.Copy();

                if (Clipboard.ContainsImage())
                {
                    images.Add(Clipboard.GetImage());
                }

                Marshal.ReleaseComObject(pic);
            }
            
            Marshal.ReleaseComObject(sheet);
            Marshal.ReleaseComObject(workbooks);
            Marshal.ReleaseComObject(workbook);
            Marshal.ReleaseComObject(sheets);
            ExcelObj.Quit();
            Marshal.ReleaseComObject(ExcelObj);

            return images.ToArray();
        }

Any ideas why this is happening? I need to be able to support 2003 and 2007/2010 with my project. 

Thanks
