Hi Everyone,

I have datagridview in that 17 columns are text columns and 5 columns are Image columns,when I'm trying to export whole gridview data's along with images to EXCEL,getting "HRESULT: 0x800A03EC" Error..While debugging the code I'm getting the error on image column not able to export..
Can anybody help us to resolve this issue..

                 if (savefile.ShowDialog() == DialogResult.OK)
                 {
                     if (!savefile.FileName.Equals(string.Empty))
                     {
                         FileInfo finfo = new FileInfo(savefile.FileName);
                         if (finfo.Extension.Equals(".xls"))
