FSUIPC Client DLL - Group '' does not exist

[ariking777]

Hello guys,

while working on a C# app I've been writing for some time, I encountered what seems to be a weird bug: when I use:

var now = DateTime.UtcNow;
FSUIPCConnection.UTCDateTime = now.AddMinutes(1);
FSUIPCConnection.Process()

I get:

An exception of type 'System.Exception' occurred in fsuipcClient.dll but was not handled in user code
Group '' does not exist.

This is after I've already established FSUIPCConnection.Open, and I have in fact passed some other changes to offset groups (set flaps, etc.). Weirdly enough, the time setting in the simulator does change, but this exception for some reason still does occur.

I've found some occurences of these in the forum, seems like they discuss initializing offsets (which in my case are long since initialized); any help would be appreciated.

Hi,

When you set the UTCDateTime property you don't need to call Process(). The process is done for you by the DLL when it sends the new date/time to FSUIPC.

I think what's happening is that you have not declared any offsets without using a group name. Process() by itself processes offsets that were not declared in a group, but you don't have any, so it throws an error.

All you need to do is take out your Process() call.

Thanks a lot, as ridiculous as that was, that fixed the problem 🙂
