writing to registry with an assembly

hi@all!

I have a component (assembly) with an object that writes data to a registry key.

When this is run from a Windows app, it works like a charm. When run from a web app, it doesnt work.

here is the code:

Code:

---



  Public Function sendandprint(ByVal path As String)

      Dim Key As Microsoft.Win32.RegistryKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\pdfMachine\BroadGun pdfMachine", True)
        Dim f As New RegistryPermission(RegistryPermissionAccess.AllAccess, Key.Name)
        f.Assert()


        Dim success As Integer
        Dim strfile As String
        Dim strpath As String
        Dim pdffile As String

        Dim reader As StreamReader = New StreamReader(path + "pdfpath.txt")
        pdffile = reader.ReadLine
        reader.Close()

        Try
            If Not IsNothing(Key) Then
                Key.SetValue("DefaultSaveDir", path)
                Key.SetValue("DefaultSaveFilename", pdffile)
                strfile = Key.GetValue("DefaultSaveFilename")
                strpath = Key.GetValue("DefaultSaveDir")
                Key.Close()
                Dim fs4 As New FileStream(path & "print.txt", FileMode.Append)
                Dim sw4 As New StreamWriter(fs4)
                sw4.WriteLine("done")
                sw4.Close()

            Else
                Dim fs4 As New FileStream(path & "print.txt", FileMode.Append)
                Dim sw4 As New StreamWriter(fs4)
                sw4.WriteLine("is nothing")
                sw4.Close()
            End If
        Catch ex As Exception
            Dim fs4 As New FileStream(path & "print.txt", FileMode.Append)
            Dim sw4 As New StreamWriter(fs4)
            sw4.WriteLine(ex.Message + " Fehler beim Schreiben")
            sw4.Close()
        End Try

End Function

thx for any suggestions u have!

greetings

where does it fail?

Is it on the registry access bit or the file writing?

The ASP.Net account may not have the required permissions to do this.

@<ABX: nothing at all... the registry seems to be written, but it is not "refreshed" cuz when i read strfile and strpath, they show me the new values. and when i open regedit i still see the old values in the registry. p.s: reboot doesnt work also.

@hellswraith: the asp.net account already has full rights, also my assembly...

thx so far,

greetings

does the aspnet acct have full access on both reg and filesystem? It might be easier to test by adding the aspnet acct to the admin group...just a thought

Hellswraith is correct, the ASPNET account (default) will not have sufficient access to the registry as it will not be a local Administrator. You can instead change IIS to use the SYSTEM account which may have sufficient access rights :thumb:
