Comment on Tutorial : How to export from DataGridView to excel using VB.net By Issac
I am using VS 2010 Express and MS Excel 2007 wherein I am trying to export data from the DataGridView into an Excel file.

xlWorkSheet.SaveAs(“C:\ExportTagDetails.xlsx”)

the above line of code works for me. But if I again try to create a file, it obviously shows the Message : ‘A file named ‘C:\ExportTagDetails.xlsx’ already exists in this location. Do you want to replace it?’
When I press Yes it creates no problem and calmly replaces itself in place of the old file. But if I click on No or Cancel then it throws an exception stating : ‘System.Runtime.Interop.Services.COMException(0x800A03EC): Exception from HRESULT: 0x800A03EC’

Here is the entire block of code :
Private Sub cmd_export_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmd_export.Click

Dim xlApp As Microsoft.Office.Interop.Excel.Application = New Microsoft.Office.Interop.Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet
Dim misValue As Object = System.Reflection.Missing.Value
Dim i As Integer
Dim j As Integer
Dim row As Long = 1

xlWorkBook = xlApp.Workbooks.Add(misValue)
xlWorkSheet = xlWorkBook.Sheets(“Sheet1″)
xlWorkSheet.Cells(1, 1).Font.Bold = True
xlWorkSheet.Cells(1, 1).Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red)
xlWorkSheet.Cells(1, 2).Font.Bold = True
xlWorkSheet.Cells(1, 2).Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red)
xlWorkSheet.Columns(1).ColumnWidth = 45
xlWorkSheet.Columns(2).ColumnWidth = 30
xlWorkSheet.Range(“A” & row).Value = “Tag Name”
xlWorkSheet.Range(“B” & row).Value = “Start Value”
row = row + 1
Try
For i = 0 To DataGridView1.RowCount – 2
For j = 0 To DataGridView1.ColumnCount – 1
xlWorkSheet.Cells(i + 2, j + 1) = DataGridView1(j, i).Value.ToString()
Next
Next

xlWorkSheet.SaveAs(“C:\ExportTagDetails.xlsx”)
Catch ex As Exception
MsgBox(ex.ToString)
End Try
xlWorkBook.Close()
xlApp.Quit()

releaseObject(xlApp)
releaseObject(xlWorkBook)
releaseObject(xlWorkSheet)

MsgBox(“You can find the file at C:\ExportTagDetails.xlsx”)
End Sub

Is there any way I can handle the issue.
Or can you provide me with a solution where the user can himself enter the name of the file and also specify the location.
Thanks in advance.
