[How to find out departure airport? and At the gate?]

What I do is grab the 23000 airports out of flight sim and place them somewhere I can get to them easily (database works good for this).

Then I check the latitude and longitude and if they are within 4 miles of where they are at then they must be at that airport.

I know that last sentence did not make any sense LOL.....

Basically you check both the latitude and longitude of the current location and match those lat,lon settings against the database.

Search google for 1 mile in latitude and longitude for calculations, I forget them at the moment.

[Simple Help Question About Offset 0609]

OK that worked for me, it was the 2 that did it.

Thanks

Now how do I know what length to use in these things. That seems to get me into trouble all the time.

As In

Call FSUIPC_Read(&H609, #, VarPtr(Engine), dwResult)

How can I find out what number to put in the # spot? For the different offsets? is there a basic outline somewhere?

[Getting GPS information]

Ok,

If you are reading strings from FSUIPC you need to convert them into charecters from the ASCII table.

First grab the info until you you find the 0 byte. This will let you know that the string of bytes have ended.

Put them into an array.

Then you can loop through the array with MyByte = MyByte & Chr(YourByte(2))

Hope this helps,

[Converting FS units to Decimal Lat/long]

This is what I use....

If FSUIPC_Read(&H560, 8, VarPtr(Fake64Bit), dwResult) Then

If FSUIPC_Process(dwResult) Then

StartLat = Fake64Bit * 10000#

StartLat = StartLat * 90# / (10001750# * 65536# * 65536#)

modVars.StartLatitude = StartLat

End If

End If

It does return a decimal like -122.23456 or something.

Fake64Bit is a Currency Declaration. It fakes VB out to grab floating 64 bit info.

If you dont force the doubles (#) you will constantly get overflow errors.

[Simple Help Question About Offset 0609]

Hey all you VB gurus out there....

How do I read the 0609 offset.

I have tried Byte, Long, Integer, Double, and nothing works. I keep getting 0 or empty.

It is the Engine Type, Byte, DEC, and should return a number.

0 = Piston

1 = Jet

5 = Turboprop

But I just cant get it to work.

Please help

Thanks.

[Calcluations]

Well, in the VB SDK it states that VB does not do 64 bit info. BUT you can cheat it.

Use a Currency variable for Floating 64

Then use that Fake64Bit and do your calculations with doubles to prevent overflows....

A = Fake64Bit

A = 360# / (65536.0#*65536.0#)

The # forces the double. Without it you will get overflow errors

[Problem With FSUIPC And VB6]

I have just one question for you VB gurus out there.

I have a form with a timer on it.

The timer sub reads info from FSUIPC when enabled.

Simple enough right.

Well it works great when I run it from inside visual studio. But when I compile and install, once that timer is enabled the whole program dissapears. No errors, no nothing.

Everything else works fine, but once the timer is enabled to read info from FSUIPC it just quits.

It doesnt do it in Visual Studio though, weird. Im confused.

Any Ideas? Need More Info?

Thanks
