Invoking the Windows Security Dialog (in C# or VB.NET)

Question

I would like to know how to invoke the Windows Security Dialog (press ctrl+alt+del on a windows workstation NOTE: I don\'t want the task manager!) programmatically.

Answer 1

This is a workaround i found on other forum. It works for me.

Private Function IsRunAsAdministrator() As Boolean

    Dim wi = WindowsIdentity.GetCurrent()
    Dim wp = New WindowsPrincipal(wi)

    Return wp.IsInRole(WindowsBuiltInRole.Administrator)

End Function

'i use it on formload, you can have it whenever needed

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    If Not IsRunAsAdministrator() Then
        Dim processInfo = New ProcessStartInfo(Assembly.GetExecutingAssembly().CodeBase)
        processInfo.UseShellExecute = True
        processInfo.Verb = "runas"
        Try

            Process.Start(processInfo)

        Catch ew1 As Exception
            MessageBox.Show("Sorry, this application must be run as Administrator.")
        End Try
        'Application.Current.Shutdown()
        Application.ExitThread()
    Else
   'your statement here
  End If
End Sub
