The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Asked by ewesley in Programming for ASP.NET, .NET Framework 2.x, Visual Studio

Tags: dialog, excel, box, open, save

Hello,

I am using asp.net with vb.net for my back code, i am successfully saving a datatable from my database as excel. I however would like to get the 'open/save as' dialog box to give the users an option to open the file immediately. Please advice, my code is below

Public Shared Sub DataToExcel(ByVal p_tablename As String, ByVal p_DT As DataTable)
        Dim oXL As Object
        Dim oBook As Object
        Dim oSheet As Object
        Dim iRow As Integer
        Dim iCol As Integer


        oXL = CreateObject("Excel.Application")
        oBook = oXL.Workbooks.Add
        oSheet = oBook.Worksheets(1)

        ' Dim sValue As String

        If oXL Is Nothing Then
            ''throw an exception
            Throw (New Exception("Unable to Start Microsoft Excel"))
        End If
        With oSheet
            'enter header to XL
            For iCol = 0 To p_DT.Columns.Count - 1
                .Cells(1, iCol + 1) = p_DT.Columns(iCol).ToString
            Next
            'enter data to XL
            For iRow = 0 To p_DT.Rows.Count - 1
                For iCol = 0 To p_DT.Columns.Count - 1
                    'start with 2nd row , 1st column
                    .Cells(iRow + 2, iCol + 1) = p_DT.Rows(iRow).Item(iCol)
                Next iCol
                'sValue = sValue & vbCrLf
            Next iRow
            oSheet.Rows("1:1").Font.FontStyle = "Bold"
            oSheet.Columns("A:A").NumberFormat = "0"
            oSheet.Columns.Autofit()
        End With

        Try
            oXL.DisplayAlerts = False
            oSheet.SaveAs(p_tablename)
        Catch
        End Try

        oXL.Workbooks.Close()
        oXL.Quit()
        While (System.Runtime.InteropServices.Marshal.ReleaseComObject(oXL) <> 0)
        End While
        oXL = Nothing
        oBook = Nothing
        GC.Collect()
    End Sub
