  1. Get values via simconnect 'execute_calculator_code'

    in FSUIPC7 MSFS

    Posted

    Hi Joe,

    I've tested the user interface here and I can't get it to throw that exception. Tried lots of reloads, lvar lists, running a client against it for 20mins etc.

    Does it happen every time you press reload?

    I also tested changing the Calc Code while it's running. Again no problems at all.  I was able to send a new calc message with different code and it just executed the last one.

    e.g. 

    {command: 'vars.calc',name: 'calc',code: '(L:ParkingBrake_Position) (>L:PJH)', interval: 200}
then
{command: 'vars.calc',name: 'calc',code: '(L:TAXI_LIGHTING_1) (>L:PJH)', interval: 200}
then
{command: 'vars.calc',name: 'calc',code: '222 (>L:PJH)', interval: 200}

    I'm not sure what's going on on your system, but I'm pretty sure the WebSocketServer code is not the problem.

  6. Key already exists exceptions

    in FSUIPC Client DLL for .NET

    HI Nabeel,

    I'm getting a lot of crashes with errors like these:

    It looks like a threading issue. It seems like my DLL is receiving simultaneous callbacks from the WASM library on different threads.

    It nothing to do with your code. 

    Quote

    Looks like they started showing up two weeks ago,

    John did change the WASM library to automatically report new LVar discoveries about two weeks ago. It could be related to that.

    I'll add some thread-safety to this part of my DLL tomorrow. Hopefully that will fix it.

  7. Get values via simconnect 'execute_calculator_code'

    in FSUIPC7 MSFS

    Posted

    I have access to MSFS for a month so I was able to try this here and it seems to work fine.

    Here is the code I ran in the Chrome console (I just modified yours to copy the parking brake into a custom LVar): 

    function Sleep(milliseconds) {
  return new Promise(resolve => setTimeout(resolve, milliseconds));
};

let calccode = {command: 'vars.calc',name: 'calc',code: '(L:ParkingBrake_Position) (>L:PJH)', interval: 200}
let declare = {command: "vars.declare",name: "myVarSet",changesOnly: true,vars: [{ name: "PJH" }]}
let read = {command: "vars.read",name: "myVarSet",changesOnly: true, interval:200}
let socket = new WebSocket("ws://localhost:2048/fsuipc/", "fsuipc");

socket.onopen = function(e) {
  socket.send(JSON.stringify(calccode));
  Sleep(200); 
  socket.send(JSON.stringify(declare));
  Sleep(200); 
  socket.send(JSON.stringify(read));
};

socket.onmessage = function(event) {
  console.log(`[message] Data received from server: ${event.data}`);
};

socket.onclose = function(event) {
  if (event.wasClean) {
    console.log(`[close] Connection closed cleanly, code=${event.code} reason=${event.reason}`);
  } else {
    console.log('[close] Connection died');
  }
};

socket.onerror = function(error) {
  console.log(`[error] ${error.message}`);
};

    If I change the parking brake the L:PJH variable gets reported as changed with the correct value. Ran fine for about 10 mins until I stopped it.

    Maybe you could try the same. If it works, it would suggest the problem is somewhere other than the socket server.

  10. Get values via simconnect 'execute_calculator_code'

    12 hours ago, joeherwig said:

    The above script doesn't retrigger the calculator codes reliable as it seems.
    The first read is correct, but afterwards I don't get any further updates.
    For offsets the regular updates are fine.

    Can you monitor those LVars (A20N_L_TK_Pump_1_Off and A32NX_OVHD_INTLT_ANN) from somewhere else (e.g. The sim, John's WASM Client) and see if they are changing or not.

    I need to know if the calculator code is not updating them, or if my server is just not sending them to you.

    Also got with Version V1.1.1 of FSUIPC WebSockets Server:

    When did you get this? It look like you pressed a button on the UI. Can you rememeber which button?

  11. FSUIPC Client DLL for .NET - Version 3 Released

    in FSUIPC Client DLL for .NET

    Posted

    Hi Peercat,

    There isn't a DisplayText() method unfortunately.

    You can display a message on the simulator screen using offsets 0x3380 and 0x32FA. (Both should have the Write-Only parameter set to True).

    Note however that this isn't working in MSFS (FSUIPC7). It does work in P3D and FSX.

    1. Declare the offsets in a group (e.g. "message") 

            private Offset<string> messageWrite = new Offset<string>("message", 0x3380, 128, true); 
        private Offset<short> messageControl = new Offset<short>("message", 0x32FA, true);

    2. Send a message  

    string Message = "my message test";
this.messageWrite.Value = Message;
this.messageControl.Value = 2; // Display for 2 seconds
FSUIPCConnection.Process("message");

    See the documentation about 0x32FA for the different values you can send for the messageControl.

  15. Program crashes with WAPID 1.0

    in FSUIPC Client DLL for .NET

    Posted

    The WAPID.dll is dynamically loaded so the compiler can't check it. I have just gone through each function and checked all the signatures (and callback signatures) manually and everything is okay. According to GitHub the .h file hasn't changed for 5 months.

    There's obviously something behaving differently in the latest WAPID/WASMIF that's causing some issues directly, or causing my use of the WAPID.DLL to be a problem now.

    King: What version of the FSUIPC_WAPID.DLL were you using before?

    I think the next step would be to get the logs that John asked for to see if those can shed any light on this.

  16. Program crashes with WAPID 1.0

    in FSUIPC Client DLL for .NET

    Posted

    Hi,

    Which version of my DLL are you using?

    The WASM system and the old FSUIPC connection do not interact at all, so I'm not sure that closing the connection is the cause.

    Quote

    I wonder if I also need to close the wapi connection too?

    You should stop the WAPI connection (MSFSVariableServices.Stop()) before you application (and therefore my DLL) gets unloaded. But the WAPI runs independently from the normal FSUIPC Connection and shouldn't be affected by opening/closing it.

    I can't test here as I don't have MSFS, but here are some suggestions:

    1. Post the details of the event log error. @John Dowson might be able to tell the cause of the crash from that.

    2. Enable the full logging (TRACE) in MSFSVariableServices. This might give some clues before it crashes.

    3. Try running the MSFSVariableServices Example Application. You'll need to update the FSUIPC_WAPID.dll to the same one you're using, and update my DLL to the latest via NuGet. See if that has any problems. If it's fine, try adding code to open and close the normal FSUIPCConnection.

  18. Airports Database - Changes in Version 3.3.0

    in FSUIPC Client DLL for .NET

    Posted

    Hi Ruediger,

    I'm almost certain there won't be any problem with this. Except for the Rebuild(), all the airports database functions open the files as read-only with shared access.

    However, at the moment the path to the internal database files is fixed and can't be changed (you'll find the DatabaseFolder property is read-only).

    You'll need this to be writable so you can set it to the folder on your network. I'll make this change and upload a new version in the next few days.

    Hi Joe,

    without the need of explicitly retriggering (polling) the calculatorCode... 

    If your calculator code is updating the LVar then it must be run at regular intervals. The only question is *where' it's being run at regular intervals. It seems like you don't want to do it in your code as it will result in a lot of network traffic.

    Would it help if I enabled the 'interval' property for the 'vars.calc' command? The websocket server would then run the calc for you every x milliseconds. If you monitor the destination LVar with changesonly then you'll just get a message when the destination lvar changes.

    Let me know if that sounds like a useable solution. But before I do the work, please check that you can indeed write to a new LVar from the calc code and read the resulting value back.

  24. Best way to make browser interface with FSUIPC?

    in FSUIPC Support Pete Dowson Modules

    Posted

    I've never used Python so I don't think I can help much.

    However, the response you're getting back is from the connection request: 

    ws = create_connection("ws://MYIP:8384/fsuipc/")

    Maybe you need to get that response first, then send your 'about' command and get the response from that: 

    import json
import websocket
from websocket import create_connection

websocket.enableTrace(True)

ws = create_connection("ws://MYIP:8384/fsuipc/")
result =  ws.recv()
print (result)

ws.send(json.dumps({"command":"about.read", "name":"about"}))
result =  ws.recv()
print (result)

ws.close()

  25. FSUIPC Client won't connect to MSFS but will connect to P3D

    in FSUIPC Client DLL for .NET

    Posted

    Quote

     any ideas on why I cant connect using the original Example project?

    It's usually because of a mismatch between the application (or Visual Studio if you are debugging) and the sim running 'as administrator'. Either both have to be running 'As admin' or neither. If one is admin and the other is not it will not connect.

    Note that this is only for FSUIPC programs. The MSFSVariableServices doesn't use FSUIPC so this rule doesn't apply for that. 

    If that doesn't fix it, please give more details like the exception that is thrown.
