Der er
1 løsning
RunAs admin
Jeg har lavet en consol applikation som laver nogle ændringer i registrerings databasen. Det kører fint når jeg selv er logget på som administrator, men når brugerne er logget på med deres konto som ikke har admin rettigheder, heller ikke lokale administrator rettigheder, så kører programmet ikke, da de ikke kan skrive i registrerings db.
Er det muligt at programmere app. så consolen bliver kørt med admin rettigheder? Jeg har jo passwordet, så det er ikke her problemet ligger.

jeg fandt en løsning:
Imports System
Imports System.Runtime.InteropServices
Imports System.Security.Principal
Imports System.Security.Permissions
Imports Microsoft.VisualBasic
<Assembly: SecurityPermissionAttribute(SecurityAction.RequestMinimum, UnmanagedCode:=True), _
Assembly: PermissionSetAttribute(SecurityAction.RequestMinimum, Name:="FullTrust")>
Public Class RunAs_Impersonator
#Region "Private Variables and Enum Constants"

Private dupeTokenHandle As New IntPtr(0)
Private impersonatedUser As WindowsImpersonationContext
#End Region
#Region "Properties"
#End Region
#Region "Public Methods"
Public Declare Auto Function CloseHandle Lib "kernel32.dll" (ByVal handle As IntPtr) As Boolean
Public Declare Auto Function DuplicateToken Lib "advapi32.dll" (ByVal ExistingTokenHandle As IntPtr, _
ByVal SECURITY_IMPERSONATION_LEVEL As Integer, _
ByRef DuplicateTokenHandle As IntPtr) As Boolean
' Test harness.
' If you incorporate this code into a DLL, be sure to demand FullTrust.
<PermissionSetAttribute(SecurityAction.Demand, Name:="FullTrust")> _
Public Sub ImpersonateStart(ByVal Domain As String, ByVal userName As String, ByVal Password As String)
Try
tokenHandle = IntPtr.Zero
' Call LogonUser to obtain a handle to an access token.
Dim returnValue As Boolean = LogonUser(userName, Domain, Password, 2, 0, tokenHandle)
'check if logon successful
If returnValue = False Then
Dim ret As Integer = Marshal.GetLastWin32Error()
Console.WriteLine("LogonUser failed with error code : {0}", ret)
Throw New System.ComponentModel.Win32Exception(ret)
Exit Sub
End If
'Logon succeeded
' Use the token handle returned by LogonUser.
Dim newId As New WindowsIdentity(tokenHandle)
impersonatedUser = newId.Impersonate()
Catch ex As Exception
Throw ex
Exit Sub
End Try
'MsgBox("running as " & impersonatedUser.ToString & " -- " & WindowsIdentity.GetCurrent.Name)
End Sub
<PermissionSetAttribute(SecurityAction.Demand, Name:="FullTrust")> _
Public Sub ImpersonateStop()
' Stop impersonating the user.
impersonatedUser.Undo()
' Free the tokens.
If Not System.IntPtr.op_Equality(tokenHandle, IntPtr.Zero) Then
CloseHandle(tokenHandle)
End If
'MsgBox("running as " & Environment.UserName)
End Sub
#End Region
#Region "Private Methods"
Private Declare Auto Function LogonUser Lib "advapi32.dll" (ByVal lpszUsername As [String], _
ByVal lpszDomain As [String], ByVal lpszPassword As [String], _
ByVal dwLogonType As Integer, ByVal dwLogonProvider As Integer, _
ByRef phToken As IntPtr) As Boolean

ByVal dwMessageId As Integer, ByVal dwLanguageId As Integer, ByRef lpBuffer As [String], _
ByVal nSize As Integer, ByRef Arguments As IntPtr) As Integer
End Function
#End Region
End Class
og i selve consol app:
Sub Main()
Dim imp As New RunAs_Impersonator
Try
imp.ImpersonateStart(domain, username, password) 'creates new context using token for user
'Din kode som skal køres med administrator rettigheder skrives her
imp.ImpersonateStop()
Catch ex As Exception 'make sure impersonation is stopped whether code succeeds or not
MsgBox(ex.Message)
imp.ImpersonateStop()
End Try
End Sub
