Re: Custom Dashboards and the Driver Station Software

Great to hear we found out what the problem was. In the meantime, a simple launchpad that prevents multiple instances can be downloaded from the CARDS FIRST Forge site at

Re: Custom Dashboards and the Driver Station Software

this sounds strangely similar to an article I read about a disabled watchdog for testing...

ZomB v0.5 will have a DashboardDataHubForm that prevents multiple instances via a system mutex. Not sure how CARDS does it
(From: http://firstforge.wpi.edu/integratio...&view =markup )

PHP Code:


		
			
[DllImport("user32.dll")]

[return: MarshalAs(UnmanagedType.Bool)]

static extern bool SetForegroundWindow(IntPtr hWnd);



...

            //Check Singleton

            bool createdNew = true;

//Create System Mutex. createNew is false if this already exists

            mutex = new Mutex(true, "ZomBSingletonMutex", out createdNew);



            if ((!createdNew) && (!DesignMode))

            {

                Process current = Process.GetCurrentProcess();

                //Don't kill designer

                if (/*Don't kill designer test here*/)

                {

                    foreach (Process process in Process.GetProcessesByName(current.ProcessName))

                    {

                        if (process.Id != current.Id)

                        {

                            //focus other

                            SetForegroundWindow(process.MainWindowHandle);

                            break;

                        }

                    }

                    current.Kill();//suicide

                }

            }

Its already in the r19 Nightly: http://firstforge.wpi.edu/sf/frs/do/...able.v0_4_1_19

Re: Custom Dashboards and the Driver Station Software

The initial version I released last night used a file for a lock, but after some trial by fire this morning at the North Star regional, it now uses a named mutex. Great minds seem to think alike. :D
