[Key already exists exceptions]

It seems like it's working as expected now

[Key already exists exceptions]

Thanks for the quick turnaround, giving it a test now

[Key already exists exceptions]

Thanks, sounds good! Yeah, with multi-threading issues, I just wanted to rule out my own code which does the same thing.

[Key already exists exceptions]

Looks like they started showing up two weeks ago, not sure if that corresponds to a release. I'm just getting back into the swing of things, I've been out of touch.

Dug another one out of error reporting

[Key already exists exceptions]

Hi,

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

Quote

System.ArgumentException: An item with the same key has already been added. Key: A320_Audio:Relay_1
  ?, in bool Dictionary<TKey, TValue>.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
  ?, in void LVarCollection.add(FsLVar lvar)
  ?, in void WAPI.fsuipcw_getLvarList(ReceiveListCallback ReceiveFunction)
  ?, in void MSFSVariableServices.refreshData()
  ?, in void MSFSVariableServices.lvarsValueChanged(IntPtr id, IntPtr Value)

With various keys. I'm not sure if there's an issue in my code; here is the init code (with simconnect):

 try {
   VS.LogLevel = LOGLEVEL.LOG_LEVEL_INFO;
   VS.OnValuesChanged += VS_OnValuesChanged;
   VS.OnLogEntryReceived += VS_OnLogEntryReceived;

   VS.Init();

   VS.Start();
 } catch (Exception e) {
   Log.Error($"Error initializing WASM module ${e.Message}");
 }

And then the stripped down code which checks, but I'm not sure there's anything here that I'm doing incorrectly.

lock (_lvarUpdateLock) {
            bool anyChanged = false;
            foreach (var fvd in AircraftFeatures.FeatureLVarIterator()) {
                if (fvd == null || string.IsNullOrEmpty(fvd.LookupKey)) {
                    continue;
                }

                if (!VS.LVars.Exists(fvd.LookupKey)) {
                    continue;
                }

                var value = VS.LVars[fvd.LookupKey].Value;

                if (fvd.Value != value) {
                    Log.Trace($"LVar {fvd.LookupKey} found changed, value={value}, old={fvd.Value}");
                }

                fvd.Value = VS.LVars[fvd.LookupKey].Value;
                anyChanged = true;
            }
...

The client DLL version is 3.3.5.405. But it doesn't seem like there's anything in my code I can update. I'm removing the VS_OnValuesChanged handler on a stop, bit I'm reorganizing this code just in case there's the callback being registered multiple times. But I don't think that'd matter in this context.

Don't worry about it - it's EOL. I have it working with "net5.0-windows10.0.18362.0", since that's what ModernWPF needs to get it working correctly. So now the FSUIPC errors have gone away - I think before it did not like multiple targetframeworks when I was trying that before, that's why I dropped to 3.1 I'd rather get 5.0 working anyway. Thanks for your time!

[.NET 6 support]

Nevermind, it looks like it should be compatible, according to: https://docs.microsoft.com/en-us/dotnet/standard/frameworks#net-5-os-specific-tfms

I'm not sure what it's complaining about... the error I'm getting is this, so I'm assuming that it's because it couldn't find the proper build platform for the FSUIPCDLL:

Severity	Code	Description	Project	File	Line	Suppression State
Error		CA0055 : Could not identify platform for 'C:\***\bin\Debug\netcoreapp3.1\win-x64\acars.dll'.	AcarsClient		1	

 

[.NET 6 support]

Hi Paul,

Sort of related - I'm updating an app from .NET 4.8 to NET Core 3.1... that's still LTS and some other libraries I use don't have 5/6 support for various reasons (damn you, WinRT...). I'm not sure which version to go with.

I'm getting this message; is it possible to have core 3.1 added?

Trying to go back to a version where I don't see dependencies:

[15:13:26 ERR] [NuGet] Package FSUIPCClientDLL 3.1.27 is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3.1). Package FSUIPCClientDLL 3.1.27 supports: net40 (.NETFramework,Version=v4.0)

 

And then with the latest:

[15:14:45 ERR] [NuGet] Package FSUIPCClientDLL 3.2.17 is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3.1). Package FSUIPCClientDLL 3.2.17 supports:
  - net40 (.NETFramework,Version=v4.0)
  - net5.0-windows7.0 (.NETCoreApp,Version=v5.0)
  - net6.0-windows7.0 (.NETCoreApp,Version=v6.0)

 

Unless I'm doing something wrong here - the targeting is really confusing and getting other (cryptic, unrelated) build errors aren't helping

[FS2004 connection]

- nevermind

[FS2004 connection]

Thanks that seemed to work. There was a mismatch - was launching FS9 as admin but Visual Studio was not. I could have sworn I ran Prepar3d as admin but I guess not. Thanks for your help!

[FS2004 connection]

Hi,

Well, a blast from a past 🙂 I'm getting this error trying to connect to FS2004 - FSX/P3D work fine. Just extending some support of my app to FS2004 by request.

{"FSUIPC Error #12: FSUIPC_ERR_SENDMSG. Error sending message to FSUIPC."}
   at FSUIPC.FSUIPCConnection.Process(Byte ClassInstance, IEnumerable`1 GroupNames)
   at FSUIPC.FSUIPCConnection.Open(Byte ClassInstance, Int32 RequiredFlightSimVersion)
   at Acars.SimClient.FsuipcClient.FsuipcClient.Connect(String address, Boolean enable_retry) in C:\...\Client.cs:line 89

I'm using this to connect:

FSUIPCConnection.Open(FlightSim.FS2K4);

I'm not sure if I'm missing something - versions are as follows:

FSUIPC DLL: 3.1.25
FSUIPC (non-registered): 3.999 (latest one available on the site)
FS2004: Latest with the 9.1 patch
Windows 10, with FS9 running in Windows 7 compat mode, as admin (both apps)

I'm not sure where to look next. Is a registered version of FSUIPC required? There doesn't seem to be anything in the logs; I've enabled IPC read/writes in the logs to see if something pop up.
