Simconnect.AddToDataDefinition – tell simconnect the the data “title” is part of the Struct1 data definition that you send to your client application and its a STRING 256 in size (managed code does not do variable strings)Īlso one for each of the other Struct1 data members you setup in the Struct1 – Altitude is a float64 Simconnect.OnRecvQuit – when you get the OnRecvQuit event message do the quit function Simconnect.OnRecvOpen – when you get the OnRecvOpen event message do the open function Then the simconnect.recieveMessage is called to trigger all the other event functions. The managed code message loop default window proc processes WM_USER_SIMCONNECT message. Simconnect.OnRecvSimobjectDataBytype += new SimConnect.RecvSimobjectDataBytypeEventHandler(simconnect_OnRecvSimobjectDataBytype) Simconnect.RegisterDataDefineStruct(DEFINITIONS.Struct1) if you skip this step, you will only receive a uint in the. IMPORTANT: register it with the simconnect managed wrapper marshaller Simconnect.AddToDataDefinition(DEFINITIONS.Struct1, “Plane Altitude”, “feet”, SIMCONNECT_DATATYPE.FLOAT64, 0.0f, SimConnect.SIMCONNECT_UNUSED) Simconnect.AddToDataDefinition(DEFINITIONS.Struct1, “title”, null, SIMCONNECT_DATATYPE.STRING256, 0.0f, SimConnect.SIMCONNECT_UNUSED). Simconnect.OnRecvException += new SimConnect.RecvExceptionEventHandler(simconnect_OnRecvException) Simconnect.OnRecvQuit += new SimConnect.RecvQuitEventHandler(simconnect_OnRecvQuit) Simconnect.OnRecvOpen += new SimConnect.RecvOpenEventHandler(simconnect_OnRecvOpen) The you set the buttons and initialize (InitDataRequest) the request and definitions and communicate that to P3D via the simconnect handle. Simconnect is the handle to the server, but is initially null, so a new simconnect object is created sending the name of the connection, a handle to your client program and the WM_USER_SIMCONNECT message to use to alert your program data is ready. Simconnect = new SimConnect("Managed Data Request", this.Handle, WM_USER_SIMCONNECT, null, 0) ĭisplayText(“Unable to connect to Prepar3D:\n\n” + ex.Message) the constructor is similar to SimConnect_Open in the native API Now P3D is running and your program is running, but there is no communication yet. All the other stuff is really for the interop – with non managed code in FSX and P3D. Simconnect sends data in packets back and forth and setting up one data entity helps make this data transfer more efficient. Struct1 is a structure you need to set up for your data request. Otherwise your program has to keep track of what “number” is used and not used. You don’t really need enum, it’s just a easy way to keep the uniqueness. Simconnect uses structures a lot.ĭATA_REQUESTS is an enumeration of any and all requests you have.Įach of these enumeration groups needs to be unique … unique enums of Definitions and a separate unique group of requests. Simconnect is the handle to the simconnect server – all programs need one.ĭEFINITIONS is an enumeration of any and all the data definition structures you have for all the data you want and send. Triggers the simconnect.recievemessage function. So when P3D has something it will send your program a message. It’s used in the simconnect “open” function. WM_USER_SIMCONNECT is a message variable that you use to tell the simconnect server (FSX or P3D) to send when something you requested is ready to be processed. this is how you declare a fixed size string
#Install simconnect prepar3d how to
simconnect knows how to fill it/read it. this is how you declare a data structure so that At this time the data members are setup and initialized. InitializeComponent does the initialization and is created by VS.
#Install simconnect prepar3d windows
The Form1 constructor builds the windows and all the other controls, buttons, edits etc. / The main entry point for the application.Īpplication.SetCompatibleTextRenderingDefault(false) Īpplication.Run(new Form1()) creates your windows and starts the window building. You use a WM_USER_SIMCONNECT message to use on this thread. You must add a reference to the simconnect managed library. The program.cs is basically the entry point for your program. You create a windows C# form program project and it creates three files. I’ll try to explain what I know about what going on in the Prepar3d managed programming examples.
