            Since few years now, there is an integrated tool to enable/disable many stuff including vnc and ssh.

            Maybe just remove the changes you've done manually before.

            Then run: sudo raspi-config

            This is a "graphical" (curses style, in console) app to changes many basic raspberry options. You should be able to enable VNC server at boot in menu "Interfacing Options".

            Running a script that starts and kills/cleans two jobs via batch file before I package it for an EXE, works great in ISE elevated but immediately fails in console or command prompt with the following:

            The code I have put together is here: https://pastebin.com/FWaZD249

            • I tested it with:
              1. PS1 to EXE, get the same results
              2. Non-elevated ISE same results
              3. Elevated console same results
              4. Elevated CMD same results
              5. Elevated ISE works (only after saving?)

            It's really close to being done, basically, it's just a little script that checks the 5900 port for established connections, updates a form of a list of connections, and sends a little notification if someone new has connected, it runs on our print server computer which is screen-shared remotely via TightVNC, so operators don't get surprised when their mouse starts moving on them.

I need that function, so it's ok for me. Today I noticed that the clipboard changed (likely because another user also connected via TightVNC).
            I didn't find a possibility to find out who connected or watched me - that's worrying me...

            Your vnc log file tells you about problem. You need to install few packages:
            sudo apt-get install metacity gnome-panel

            UPDATE 1:

            You need only x-window-manager or metacity. Both provides window manager and you need only one. From screenshot I see only two problems - grey screen and missing indicators.

            To fix missing indicators install one more package:
            sudo apt-get install indicator-applet-complete

            To fix grey screen you need --force-desktop commandline option. And if you don't want default nautilus window you can add --no-default-window:
            nautilus --force-desktop & or nautilus --force-desktop --no-default-window

            Also GNOME Flashback (Metacity) session in Ubuntu 16.10 use unity-settings-daemon not gnome-settings-daemon. Don't forget to install it if you decide to change that.

            Disable mouse click on certain area of the windows screen c# wpf
            Asked 2017-Aug-02 at 06:28

            I have a situation where I would like to give remote access to a client using TightVNC to allow them to perform some tasks on a third party application.

            I am wanting to only allow them to click on certain parts of the screen e.g. disable the 'Close' button, with a few areas disabled. I was wondering if there was a way to programmatically intercept the mouse down event on windows and if they mouse down on a particular area just return instead of performing the click? Or if there is a way to overlay a transparent background which is always at the front of the screen in the chosen areas?

            My application is written in WPF c# so if there are any examples to achieve this it would be greatly appreciated. I have tried creating some dummy transparent windows, the problem is that when the user clicks on the other application they go to the background hence defeating the objective.

            Thanks in advance.

            Option 1:

            You should technically be able to attach global hooks for mouse events and suppress them when you need to. globalmousekeyhook is one of the libraries available for assigning handler(s) to mouse events and suppress them conditionally by setting e.Handled = true.

            Option 2:

            In case you need to block mouse events only for specific applications - then you can override their WindowProc method to filter or suppress particular region based mouse-events.

            For example, for a windows forms application, you can use following code to disable mouse clicks in fourth quadrant region of the window. (Note: this code needs to be added to the application you are trying to block access to)

            Multiple integer signedness errors in (1) UltraVNC 1.0.2 and 1.0.5 and (2) TightVnc 1.3.9 allow remote VNC servers to cause a denial of service (heap corruption and application crash) or possibly execute arbitrary code via a large length value in a message, related to the (a) ClientConnection::CheckBufferSize and (b) ClientConnection::CheckFileZipBufferSize functions in ClientConnection.cpp.
            Vulnerability in VNC, TightVNC, and TridiaVNC allows local users to execute arbitrary code as LocalSystem by using the Win32 Messaging System to bypass the VNC GUI and access the "Add new clients" dialogue box.
            TightVNC before 1.2.4 running on Windows stores unencrypted passwords in the password text control of the WinVNC Properties dialog, which could allow local users to access passwords.
