Payload stations

[Emanuele]

Hi Paul,

 

I write to you because i'm not able to understand how works payloads' function on new DLL.

 

I read this

' Get a reference to save so much typing...
Dim ps As PayloadServices = FSUIPCConnection.PayloadServices

' Get the latest data from FSUIPC

ps.RefreshData()

 

But in my development PC i haven't FSX and FSUIPC. FSX runs in another one PC. So, how can i test the program in development status?

 

Continuing reading, i see this:

 

You also have access to the individual payload stations and fuel tanks. Here is an example of iterating through each payload station.

' Go through each station and get the name and weight
For Each (payloadStation As FsPayloadStation In ps.PayloadStations)
Dim name As String = payloadStation.Name
Dim weight As Double = payloadStation.WeightLbs
Next payloadStation

 

So I don't understand how DLL can get the name payload stations using this cycle. Probably it's a my mind fault...

i'm so confusing because i'll works with 16 payloads stations and for each one i'll have a precise wheight to load

 

station_load.0 ="0, 16.6853104911779, 0.0, 0.0, Cabin 0A" 

station_load.1 ="0, -1.12441769194083, 0.0, 0.0, Cabin 0B"

station_load.2 ="0, -19.4743461611827, 0.0, 0.0, Cabin 0C"

station_load.3 ="0, 19.1162117787317, 0.0, 0.0, cargo11"        

station_load.4 ="0, 14.5385770624704, 0.0, 0.0, cargo12"

station_load.5 ="0, -8.29051211254223, 0.0, 0.0, cargo41"        

station_load.6 ="0, -14.5070357176912, 0.0, 0.0, cargo42"

station_load.7 ="0, -22.8196489747242, 0.0, 0.0, cargo51"

station_load.8 ="0, 35.2358280372542, 0.0, 0.0, Pilot/copilot"

station_load.9 ="0, 32.9187924962841, 0.0, 0.0, Trainers"

station_load.10 ="0, 28.5715924813225, 0.0, 0.0, Crew1"

station_load.11 ="0, -28.074409744078, 0.0, 0.0, Crew2"

station_load.12 ="0, -31.4506615323471, 0.0, 0.0, Crew3"

station_load.13 ="0, 28.9467315689077, 0.0, 0.0, Crew4"

station_load.14 ="0, 4.93782996344077, 0.0, 0.0, PantryA"

station_load.15 ="0, -15.9676482810941, 0.0, 0.0, PantryB"

 

Finally, what are the differences between Process() and WriteChanges()

 

Thank for your help, regards

But in my development PC i haven't FSX and FSUIPC. FSX runs in another one PC. So, how can i test the program in development status?

 

 

 

You need to have FSX running on the same PC. Or, if you have a WideFS licence, you can run WideClient.exe instead. This will connect to the FSX computer and is a tiny program compared to FSX.

 

So I don't understand how DLL can get the name payload stations using this cycle

 

 

 

You cannot get a payload station by name because Flight Sim allows duplicate names for payload stations. For example the stock Cessna C172 has two payload stations called 'Rear Passenger'.

 

If you want to load (update) all the payload stations at once, use a 'select' statement. This example loads the station weights from text boxes on the form. I've only shown two stations to keep it short.

        Dim ps As PayloadServices = FSUIPCConnection.PayloadServices
        ps.RefreshData()
        For Each payloadStation As FsPayloadStation In ps.PayloadStations
            Select Case payloadStation.Name
                Case "Cabin 0A"
                    payloadStation.WeightKgs = txtCabinA.Text
                Case "Crew1"
                    payloadStation.WeightKgs = txtCrew1.Text
            End Select
            Dim weight As Double = payloadStation.WeightLbs
        Next payloadStation
        ps.WriteChanges()

If you want to access payload stations individually then you use the index, not the name. This example updates the Crew1 station - the index of this station is 10:

 

station_load.10 ="0, 28.5715924813225, 0.0, 0.0, Crew1"

        ps.RefreshData()
        ps.PayloadStations(10).WeightKgs = txtCrew1.Text
        ps.WriteChanges()

Finally, what are the differences between Process() and WriteChanges()

 

 

 

Process() is on the FSUIPCConnection class. This will read or write the data in all the offsets you have declared in your application. It does nothing for PayloadServices.

 

WriteChanges() is on the PayloadServices() class. This will write any changed to payload information you have made. It does not write any offsets you have declared. When you use PayloadServices you don't need to use Process().

Paul,

 

one question:

 

during   ps.RefreshData()

             ps.PayloadStations(10).WeightKgs = txtCrew1.Text
             ps.WriteChanges()

 

the connection must be open?

 

Thanks

[Paul Henty]

Yes you need an open connection.

[Emanuele]

Yes you need an open connection.

ok thanks
