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..
Here is my code which i used:
private void btnexportexcel_Click(object sender, EventArgs e)
try
SaveFileDialog savefile = new SaveFileDialog();
savefile.Filter = "Excel (*.xls)|*.xls";
if (savefile.ShowDialog() == DialogResult.OK)
if (!savefile.FileName.Equals(string.Empty))
FileInfo finfo = new FileInfo(savefile.FileName);
if (finfo.Extension.Equals(".xls"))
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.Application();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(2) ;
int i = 0;
int j = 0;
for (i = 0; i <= dataGridView1.RowCount - 1; i++)
for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)
DataGridViewCell cell = dataGridView1[j, i];
xlWorkSheet.Cells.Borders.LineStyle = Excel.XlLineStyle.xlContinuous;
xlWorkSheet.Columns.AutoFit();
if (cell.Value.GetType() == typeof(Bitmap))
string image =Convert.ToString(dataGridView1.CurrentRow.Cells[i].Value); 
Excel.Range oRange = (Excel.Range)xlWorkSheet.Cells[i + 1, j + 1];
float Left = (float)((double)oRange.Left);
float Top = (float)((double)oRange.Top);
const float ImageSize = 32;
xlWorkSheet.Shapes.AddPicture(image, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, Left, Top, ImageSize, ImageSize);
oRange.RowHeight = ImageSize + 2; 
else
xlWorkSheet.Cells[i + 1, j + 1] = cell.Value;
xlWorkBook.SaveAs(savefile.FileName, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue,
Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
MessageBox.Show("Excel file created , you can find the file " + savefile.FileName);
else
MessageBox.Show("Invalid file type");
else
MessageBox.Show("You did pick a location " + "to save file to");
catch (Exception ex)
MessageBox.Show("Exception Occured", ex.Message);
