I did, and it didn't work. I tried with a button click to increase it by 1 or 2, then I tried hooking up a keydown event in a textbox to see if that would work. Still doesn't work. These aren't the only 'knobs' I am having problems with either. The cargo temp panel in overhead maint has temp knobs. They are giving me the same problem. Sending any type of value fails unless the 777 directly changes it with a state load.

Hi, I am trying to set the position of the lighting knobs in the PMDG777 for MSFS2020. Unfortunately, nothing I do seems to work. I know it has something to do with the parameters I am sending, because the values change in our app when the 777 changes the values itself. EG: when loading a panel state. Here is an example from the master brightness knob. The other ones like circiut breaker, glare shield, overhead, and dome light are probably the same. The SDK states that the valid values are 0-100 for all of them. However, sending a left click, right click, mouse wheel up, mouse wheel down, left drag, or right drag don't change the values. What do I send for the parameters? I figured I would come here and ask because I am using your library. Here is what I have (C#) in dotnet 9.0. FSUIPCConnection.SendControlToFS(PMDG_777X_Control.EVT_OH_MASTER_BRIGHT_ROTATE, ...);

Can you let me know when you are done?

Yes, it appears to be stable. I tried it around 20 times in the debugger, and none of them threw the protobuf error. Out of interest, is the entire airports database thread safe, or only parts of it? Just wondering, because we use it in a multi threaded environment quite often.

I don't think this has anything to do with make runways, but this is what I get now. I never modified my code, so it is the same as before.

Hi, It happens with most airports, especially in the United States. A prime example that gives me this problem is KSFO, KLAX, or anything on the west coast. Sometimes KJFK and KBOS do it, but it is almost nonexistent. I also noticed that when I pull out if the player is on the runway, and what runway they are on, I get unpredictable results. A good example is runways 24 and 25 at KSFO. Going into KRNO last night to runway 17R, my PMDG738 had CMDA and CMDB on, landed on the runway, but the scenery extract from the airports database was telling me that I wasn't on a runway at all. Visually, the landing was perfect. I am running the newest library version. This is MSFS2020. We aren't using 3rd party scenery, only the MSFS2020 default.

Hi, I get the following exception when doing the following: Public PlayerInfo CurrentLocation { get => FSUIPCConnection.AirportsDatabase.GetPlayerLocation(AirportComponents.All); } Here is the error I get. Strangely enough, the airports database built without problems. How would I fix this? The only way I get the below is to run it through the debugger in Visual Studio 2022.

Yes, it works just fine in my setup. My aircraft heading and the runway heading might be off by a degree or so, but I never ran off the runway like that. One of my staff members reported some time ago that he used our app to reposition to the runway, attempted o takeoff, and crashed into something. When he reloaded and used GSX or another app to reposition to the runway, he didn't crash. Nobody can confirm if it is because make runways data is bad, because our app rounds headings to the nearest degree, or both, but I guess it is a problem. I can't even confirm if our app is to blame for his crash or many of our users getting placed off the centerline.

Hi, When using the built-in move aircraft method for a runway, users are reporting that it is putting the aircraft to the left or right of the centerline, not directly on the centerline. This is also reported by Vatsim ATC as well. Here is a little sample of how we use the MoveAircraftHere method for a runway. Is there a way to get i to put us on the centerline of the runway? Users are also reporting that it puts them in a strange location on the runway such as a taxiway or not on the lineup or holding point. if(row is RunwayDataGridRow runwayData) { var airport = FSUIPCConnection.AirportsDatabase.Airports[airportIcaoTextBox.Text.ToUpper()]; airport.LoadComponents(AirportComponents.Runways); var runway = airport.Runways[runwayData.ID.ToString()]; runway.MoveAircraftHere(false); this.Close(); }

Got this to work. All I had to do is add a firstRun flag. Set it to true by default, then at the end of the constructor, set it to false after a 500ms delay. Then, in each event handler implementation, put this at the top of the event handler. Private Void AnnounceSomething(Object sender, PMDG777ValueChangedEventArgs e) { if(isFirstRun) return; // Rest of the code. } Works perfectly, and it doesn't interfere with the rest of the working code. I still am going to create public methods for attaching/detaching different groups of events in case I need to use them.

So, for example, in my main window, I have a menu item that when clicked, creates an instance of this class and assigns it to a property in another class. Once that is done, the menu item's click event can attach the event handlers. This should stop the spam when the 777 loads?

I have event handlers that handle the announcement of offset values when they change. So far, everything is working perfectly. However, when starting our app, we get announcements for different 777 controls. Some of them include MCP heading, MCP speed, MCP altitude, flight director status, and auto throttle left/right status. Given the class partials below, is there a way to stop these announcements while the class instance is created? We need it to be silent during startup. I tried setting a loaded or initialized flag, but that doesn't really work. It seems that when the timer starts, it triggers the event handlers in mass for the first time - this is what we need to deal with I think. using tfm.Utilities; using tfm.Airplanes.PMDG777.Shared; using System.Windows.Threading;

I am using version 3.12 of your library.

Hi, Here is what I find with 'testing'. * Offsets work in a simple test app (WPF). * Offsets work in the previous version of our app. * In the new design (wpf/dotnet 8.0), offsets work. However, it seems as though they don't receive an initial value until the timer can tick at least once. When the process timer ticks, the initial value doesn't change, so nothing happens. To demonstrate, I will explain what happens. The example is the aircraft title (0x3d00). When the base Aircraft instance is created through inherited classes (the PMDG737/777). The class creates an instance of Offset<string>(0x3d00, 256) and assigns it to a variable _title. In the constructor of base Airplane class, I start a timer that checks for _title.ValueChanged. If it has, perform some logging to track the value. In this example, the _title offset is always empty, so nothing ever happens. Even though process is called elsewhere (connection manager), the offset's initial values are not loaded. On the other hand, calling Process outside a timer while in the constructor seems to load the initial data into the offsets. I'm confused with the entire issue. I am not using DispatcherTimer in any of my non UI classes. Could this be causing the problem? * An instance of Airplane is created. * Start a process timer. * In the timer event, check for changes to the title offset. * Do an action if it changes. * The title offset is empty because it never arrives at its MSFS provided value.

This still didn't work. I can send you the entire app for a lookover if it would help.
