Hi, Thanks very much for your help - I had somehow forgotten there was more than one sets of offsets for the weather - I've shifted it all up to run from 0F1C through to 0F8A and it all works wonderfully now! I'm not too worried about the weather changing or re-localising - I will be resetting the weather every 5 or 10 minutes with the way the simulator is going to be used anyway. I was trying to avoid the NWI because I'm not 100% sure of version of FSUIPC that my software is going on to. Thanks again for the help! By the way, I've had a scan through the list of offsets and couldn't see anything, but I don't suppose there is any way through FSUIPC of telling whether FS is in full screen or just normal maximised mode is there? Thanks again. Jags

{Error Post After Login} EDIT: Strange error, but this is basically my original post: I have been trying to alter the weather through FSUIPC - I want to be able to set Wind, Visibility, Cloud and Precipitation - so far what I have done is retrieved offsets 0E9A through to 0F08 in a for loop at 2-byte intervals, stored the results in an array, altered the ones I want to set and then written them back into their offsets. (With the addition of 0E8A and 04D2 for Vis and Precipitation). However, whever I set any weather, it for some reason sets the wind back to 340/00 (or 000/00 if you read the offsets), regardless of whether or not I set wind in the offsets. Any help would be appreciated ;) Jags

That works an absolute treat!! Thank you SO much!!! :D And I also apologise for my apparent inability to understand the basic concepts of numbers :oops: !! I've certainly learned something from that! James

I am trying to write a procedure that will set the speed of the aircraft (I call it after I have slewed the aircraft to a certain position and altitude, then released slew). Using the example by "timsc" I manage to get the speed of the aircraft to change to a value other than the default slew-release value, but could not identify any positive relationship between these numbers and the airspeed (or Z-Velocity). I have written the following code now, but this seems to have no effect on the speed at all - no matter what numbers I enter: Procedure FSUIPCCalls.SetSpeed(aIAS : Integer); var ErrorNumber : Cardinal; pIAS : PInteger; begin New(pIAS); pIAS^ := aIAS; FSUIPC_Write($3090,4,pIAS,ErrorNumber); FSUIPC_Process(ErrorNumber); Dispose(pIAS); end; I'm just a tad confused about how I can get a reliable procedure to change the speed. Thanks very much!! Jags

Sorry to resurect such an old topic but I would like to quickly ask... from Knots, how do I convert this into these "Hi" and "Lo" numbers? I'm programming this in Delphi, in which I have a bit of experience, but I'm just not entirely sure how all these integers, bits and hi/lo bits work! Thanks very much Jags
