windows - Is it possible to duplicate the following credential process in VB.NET? -


solution (short):

safety net is only allowed with the use of application-level Excludes impersonation. Since the COM object is at the system level, therefore the impersonated user can still not instantize. I understand this program by right-clicking on it executable and selecting "run edge ...". I came to know that the program has been launched with system access (it is believed that the user with which you are running this is the credentials). I am now in the process of creating an external program that will launch this application using this method.

Thanks for the tips: D

I have a Windows XP installation to a virtual machine that is part of my domain, but the logged-in user only has a local user course If I try to share a network, then it will prompt for the user / password:

The program I am testing on a virtual machine uses a COM object Interface with the other Data from Rogram if I do not impersonate, then I get errors because I do not have the proper credentials.

I did some research in this matter and saw many websites, which had a good amount of VB.NET information. The problem is happening with the code I wrote that I can access network resources, but I have a COM object Can not illustrate

If I fill the credentials quickly (above) before filling and making this illustration, it works great. It leads me to believe that the WinXP Credential Prompt is doing something that I'm not. The code below is what I'm using for impersonation: 

  public sub BeginImpersonation () integer as Const LOGON32_PROVIDER_DEFAULT = 0 Const LOGON32_LOGON_INTERACTIVE int = 2 Const integer as SecurityImpersonation = 2 slow win32ErrorNumber as integer as _tokenHandle = IntPtr .Zero _dupeTokenHandle = IntPtr.Zero then logonUser (_username, _domainname, _password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, _tokenHandle) then win32ErrorNumber = System.Runtime.InteropServices.Marshal. GetLastWin32Error () Throw New ImpersonationException (win32ErrorNumber, GetErrorMessage (win32Erro RNumber), _username, _domainname) If not, duplicate token (_tokenHandle, SecurityException, _dupeTokenHandle) then Win32ErrorNumber = System.Runtime.InteropServices.Marshal.GetLastWin32Error () CloseHandle (_tokenHandle) throw new impersonation option (win32ErrorNumber, "Duplicate token unable! "_ujhmnem, _domainname) finally dim newId New (as System.Security.Principal.WindowsIdentity (_dupeTokenHandle) _impersonatedUser = newId.Impersonate) _impersonating = true end Sub

I Also tried to send different flags to the unknown method, but to do some work Ap- pears here given different flags: 

  Enum LOGON32_LOGON Intraktiiv = 2 network = 3 Batch 4 = Service = 5 unblocked = 7 Netvrkr_elaaraarakt = 8 Nukauntantial = 9 and Enum Enum LOGON32_PROVIDER [DEFAULT] = 0 WINNT35 = 1 WINNT40 = 2 WINNT50 = 3 end Enum Enum SECURITY_LEVEL Anonymous = 0 identity = 1 impersonate = 2 delegation = 3 end Enum

I have finished before this, and used two different soloution - one third cross easiest T application was using: TqcRunas: which allows you to stay creentials package in an encrypted file. Although there is a pain, the password is forced to expire.

The other solution that I have used is to call a new process with alternative identification. 

  dim myProcessStartInfo as ProcessStartInfo = myProcessStartInfo. New ProcessStartInfo = "File Path and Name" with FileName .Domain = "domainname" .UserName = "UserName" 'Password One SerureString Each C Need to use NewPassword as "New Security.SecureString as NewPassword for Password" in the form of four. "ToCharArray .AppendChar (c) Next c .makeReadOnly () with .Password = NewPassword.Copy using the end 'UseShellExecute process with the form of new System.Diagnostics.Process as well as using the process as a model Finish or be false to .UseShellExecute = False End. StartInfo = myProcessStartInfo. Start using the end of ND

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
