"PAYLOAD STATION NAME"

[DragonflightDesign]

As a follow-on from my previous question, can anyone confirm if the above is another non-working variable?

' Create the definition
p3d_simconnect.AddToDataDefinition(P3Data.DefinePayloadStations, "PAYLOAD STATION NAME:1", "string", SIMCONNECT_DATATYPE.FLOAT64, 0, 600)
' Request the payload station name
p3d_simconnect.RequestDataOnSimObject(P3Data.RequestPayloadStations, P3Data.DefinePayloadStations, SIMCONNECT_SIMOBJECT_TYPE.USER, SIMCONNECT_PERIOD.SECOND, SIMCONNECT_DATA_REQUEST_FLAG.DEFAULT, 0, 0, 0)

I'm getting an exception 7 followed by an exception 3, which is what I'd expect if the variable is defective.

n/m. Sometimes I'm a real idiot. Spot the ballsup....

Nope. Still can't Can get it even after correcting the obvious problem.

' Create the definition
p3d_simconnect.AddToDataDefinition(P3Data.DefinePayloadStations, "PAYLOAD STATION NAME:1", Nothing, SIMCONNECT_DATATYPE.STRING256, 0, 600)
' Request the payload station name
p3d_simconnect.RequestDataOnSimObject(P3Data.RequestPayloadStations, P3Data.DefinePayloadStations, SIMCONNECT_SIMOBJECT_TYPE.USER, SIMCONNECT_PERIOD.SECOND, SIMCONNECT_DATA_REQUEST_FLAG.DEFAULT, 0, 0, 0)

The struct returns 'Nothing' in the stationName1 field.

FWIW:

Using the C# Managed Data Request sample from the FSX SP2 SDK, I was able to get a station name.

But, it was only one. It can be for any station number.

If I asked for more than one string in this sample, the app would crash.

I've never needed more than one string returned in SimConnect, so I've never tried to see how it is done. And, my lack of programming knowledge doesn't help.

simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "Payload Station Name:1", null, SIMCONNECT_DATATYPE.STRING256, 0.0f, SimConnect.SIMCONNECT_UNUSED);

void simconnect_OnRecvSimobjectDataBytype(SimConnect sender, SIMCONNECT_RECV_SIMOBJECT_DATA_BYTYPE data)
{
      switch ((DATA_REQUESTS)data.dwRequestID)
      {
         case DATA_REQUESTS.REQUEST_1:
              Struct1 s1 = (Struct1)data.dwData[0];

              //  displayText("Title: " + s1.title);
              displayText("Name: " + s1.payloadstationname1);
              displayText("Lat:   " + s1.latitude);
              displayText("Lon:   " + s1.longitude);
              displayText("Alt:   " + s1.altitude);
              break;

I hope that with all your experience that you will know out how to make it work like you want.

It's a serious PITA because you have to resort to System.Reflection to query the value of each station name, particularly when you assume you don't know how many stations there are going to be. I did eventually get all of them (and their associated weights) but it took nearly three hours of trying because I'd never used System.Reflection before. Annoyingly, it turned out to be really easy once I'd fought my way through documentation, trial and error.

It's not something I'm keeping to myself either. I've greatly expanded (and improved!) the original VB Managed Data Request and intend to publish it once I've written something to accompany it. It'll probably go in the next issue of sd2gau.
