Hi Paul, Thank you very much for the explanation. I am using the DLL in SBuilder (scenery creation programme) and I get an error in the situation that I will try to explain: My programme has an option to show the FS aircraft on the Sbuilder display. When the user sets this option and until he disconnects the option, the programme displays the aircraft position at regular intervals (set by a timer). This is the code for the timer event: Try FSUIPCConnection.Process() AircraftLatitude = CDbl(LatAircraft.Value) AircraftLatitude = AircraftLatitude * 90.0 / (10001750.0 * 65536.0 * 65536.0) AircraftLongitude = CDbl(LonAircraft.Value) AircraftLongitude = AircraftLongitude * 360.0 / (65536.0 * 65536.0 * 65536.0 * 65536.0) Catch ex As Exception MsgBox("Error communicating with FSUIPC!", MsgBoxResult.Ok) AircraftVIEW = False ShowAircraftMenuItem.Checked = False Me.Timer2.Enabled = False Exit Sub End Try UpdateDisplay() This runs fine except if the user closes FS. Then SBuilder (in debug mode) reports an error in the DLL or it crashes in normal operation. I could start the shown routine with: Try FSUIPCConnection.Close() FSUIPCConnection.Open() FSUIPCConnection.Process() ... but this does not look good as the timer interval can be very short (100ms or so depending on the settings of the user of my programme). Many thanks for any tip, Regards, Luis

Hi, I can not read aircraft position using this DLL. Could anyone be so kind to post the code to get the latitude (or longitude) of the aircraft? Luis

Hello, There was a bug in my implementation :mrgreen: . For the benefict of other users here is a correction: Public Function fsUIPCSetLatitude(ByVal Latitude As Double) As Integer In the fsUIPCSetLatitude function the variable Latitude can not be passed by reference (by reference is default in VB). The crash was in my application because the function modified the Latitude. Regards and many thanks to Pete for providing an application key for SBuilder, Luis

Hello, I wonder if any VBasic programmer can help me in writing the code for my applycation to set the aircraft position through FSUIPC. I got a "developer key" from Pete but debugging is very difficult as I need to run a full compiled version for FSUIPC to accept my application's requests. My application is scenery generation programme and I only need to read and to write the aircraft lat/lon. I followed the examples in the FSUIPC SDK and I can read the aircraft position. But when I try to set the aircraft position there is an overflow and my application crshes. Following is the routines to read (which works fine) and to write (which does not) the latitude. Any comment would be most apreciated. Regards, Luis Public Function fsUIPCGetLatitude(Latitude As Double) As Integer Dim Fake64Bit As Currency Dim dwResult As Long fsUIPCGetLatitude = 0 If FSUIPC_Read(&H560, 8, VarPtr(Fake64Bit), dwResult) Then If FSUIPC_Process(dwResult) Then Latitude = Fake64Bit * 10000# Latitude = Latitude * 90# / (10001750# * 65536# * 65536#) Else fsUIPCGetLatitude = 1 End If Else fsUIPCGetLatitude = 1 End If End Function Public Function fsUIPCSetLatitude(Latitude As Double) As Integer Dim Fake64Bit As Currency Dim dwResult As Long fsUIPCSetLatitude = 0 Latitude = (Latitude / 90#) * (10001750# * 65536# * 65536#) Fake64Bit = Latitude / 10000# If FSUIPC_Write(&H560, 8, VarPtr(Fake64Bit), dwResult) Then If FSUIPC_Process(dwResult) Then Else fsUIPCSetLatitude = 1 End If Else fsUIPCSetLatitude = 1 End If End Function

Hello Pete, I was not sufficient clear in my message. I am very sorry. I am the author of the programme. I could not find your email to ask for a key. In fact I am using another module to read Aircraft position (Latitude and Longitude). Then I display the aircraft in my programme console. The other funcionality that I would like to implement is to force the FS Aircraft to go the area that my programme is working (this funcionality does not work with the module that I am using). In conclusion I would like to know if I could integrate your software in my programme. I only need the functions: set aircraft lat set aircraft lon read aircraft lat read aircraft lon and if possible set aircraft altitude read aircraft altitude Kind Regards, Luis

Dear Pete, SBuilder is a FS2004 scenery design programme which is available as freeware (whith a small restriction thought). http://www.ptsim.com/forum/forum.asp?FORUM_ID=18 I would like to know if I could use your module. Kind Regards, Luis
