• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Keypress multiple events


I am using SimConnect with MSFS2020.
I am capturing keypresses using the technique from the sample InputEvent, only modified for C#.

For a single keypress, SimConnect receives 5 or 6 (or more) events from MSFS.
I have verified this using FSUIPC logging.

I have tried to remove notifications when processing the first event but it has no effect on arriving events.

I am currently using a time based block where I ignore the events for a couple of seconds after the first one arrives.

This is a nasty solution as sometimes the user may want to press the key again and the block then impedes them. ;-(

Does anyone have a suggestion on a proper way to stop, or better deal with, the multiple keypress events?

Gave up with SimConnect keypress, and switched to low level keyboard hook.
Works sort of... captures keys fine but even captures when another app is running (not good)
Better if I could make the SimConnect keypress work properly.

Modified keyboard hook to only look at MSFS :)
