@msdn=http://search.microsoft.com/search/results.aspx?qu=$$$ @pinvoke=http://pinvoke.net/$$$.htm Summary: The WTSDisconnectSession function disconnects the logged-on user from the specified Terminal Services session without closing the session. If the user subsequently logs on to the same terminal server, the user is reconnected to the same session. !!!!C# Signature: [DllImport("wtsapi32.dll", SetLastError = true)] static extern bool WTSDisconnectSession(IntPtr hServer, int sessionId, bool bWait); !!!!VB Signature: <DllImport("wtsapi32.dll", SetLastError:=True)> _ Private Shared Function WTSDisconnectSession(ByVal hServer As IntPtr, ByVal SessionId As Integer, ByVal bWait As Boolean) As Boolean End Function !!!!User-Defined Types: None. !!!!Notes: Note that you cannot disconnect the console session. To indicate the current session, specify WTS_CURRENT_SESSION. To retrieve the identifiers of all sessions on a specified terminal server, use the WTSEnumerateSessions function. To be able to disconnect another user's session, you need to have the Disconnect permission. !!!!Tips & Tricks: Please add some! !!!!Sample Code: Friend Function DissconnectSession(ByVal ServerName As String, ByVal SessionID As Integer) As Boolean Dim RetVal As Boolean Dim ptrOpenedServer As IntPtr Try ptrOpenedServer = WTSOpenServer(ServerName) RetVal = WTSDisconnectSession(ptrOpenedServer, SessionID, False) Catch ex As Exception Throw New Exception(ex.Message & vbCrLf & System.Runtime.InteropServices.Marshal.GetLastWin32Error) Finally Try WTSCloseServer(ptrOpenedServer) Catch ex As Exception End Try End Try Return RetVal End Function !!!!Alternative Managed API: Do you know one? Please contribute it! !!!Constants: WTS_CURRENT_SERVER_HANDLE = IntPtr.Zero WTS_CURRENT_SESSION = -1 !!!Switch User: [DllImport("wtsapi32.dll", SetLastError = true)] static extern bool WTSDisconnectSession(IntPtr hServer, int sessionId, bool bWait); public static void SwitchUser() { WTSDisconnectSession(IntPtr.Zero, -1, false); } Documentation: WTSDisconnectSession@msdn on MSDN
