Has anyone tried the Managed VB Data request and got it to work?I keep getting an "Exception from HRESULT: 0xC000020D" when it try to connect to FSX.Not having much luck finding out what it mean or how to fix the problem either.Any help appreciated.Rory

Yes it works. Did you try the classic methods such as:- Switch off firewalls and virus scanners- Reinstall SimConnect by deleting the DLL from C:WINDOWSWinSxS... blah blah and running FSX installation in repair mode again- perhaps disable other simconnect clients if there are others active while testing

Yes, did all that before i posted as still nothing!Was wondering if anyone knew what the error message meant, NOTHING is being blocked!

HRESULT 0xC000020D means STATUS_CONNECTION_RESET in some windoze header file.It seems that when you call SimConnect_CallDispatch the tcp/ip connection got already reset (closed). You should write a SimConnect.ini (how to is in the SimConnect SDK doc) to save or view the simconnect log and perhaps try to see the reason there. Although this tastes really like either a firewall problem or perhaps another application is listening to the ports used by simconnect or something like that.
