Web config access denied

A Common developer problem

I have multiple local web servers , (developing, testing and production servers) when I copy my application between these servers I get this common error, and the IDE says cant start debugging and so on , so my work around is as follow:
  • Remove your files and folders from your application directory (normally under C:\Inetpub\wwwroot/ExampleApp) to another folder
  • Delete the folder and recreate it with IIS
  • Tasks-new virtual directory- entry alias- make a folder, etc
  • Then copy and past (not cut and past) the content to the new directory

This normally is a work around but I don’t think it’s the right solution
I think its something about permissions

Export Local Reports to Excel/PDF with one click

Local report are great but without an export function so this is one of my approaches to solve this issue.

ReportName : you give the name of the report and its reference path
ReportType : is an enum that is define after the subroutine (Excel/PDF)
DS : is the data set that contain all the information to link with the data
DSName: is the name of the data set so the binding will work

Private Sub ExportReport(ByVal ReportName As String, ByVal ReportType As ReportExportTypes, ByVal DS As DataSet, ByVal DSName As String)
'create report
Dim V As New ReportViewer
V.ProcessingMode = ProcessingMode.Local
V.LocalReport.ReportPath = Server.MapPath(ReportName)
For Each t As DataTable In DS.Tables
V.LocalReport.DataSources.Add(New ReportDataSource(DSName + "_" + t.TableName, t))
' export report
Dim warnings As Warning() = Nothing
Dim streamids As String() = Nothing
Dim mimeType As String = Nothing
Dim encoding As String = Nothing
Dim extension As String = Nothing
Dim bytes As Byte()
bytes = V.LocalReport.Render(ReportType.ToString, Nothing, mimeType, encoding, extension, streamids, warnings)
'start exporting
Response.Buffer = True
Select Case ReportType
Case ReportExportTypes.Excel
Response.ContentType = "application/"
Case ReportExportTypes.PDF
Response.ContentType = "application/pdf"
End Select
Dim oStream As New IO.MemoryStream(bytes)
'cleaning up
End Sub

Public Enum ReportExportTypes
End Enum
