Is there a way to SuppressKeyPress?

[tkefauver]

Hi! First just wanted to say thank you for this very handy library which has been working great for me :)

But I am trying to handle hotkey sequences in my program and in the past have used e.SuppressKeyPress (in winforms) when the user is inputting a possible hotkey sequence but I haven't found a method to do so with SharpHook.

Any idea how I could handle this platform independently?

Hi! Thanks for asking!

Yes, suppressing input events is possible, but I guess it's not quite clear. The HookEventArgs class contains the Reserved property which you can use to suppress an event:

e.Reserved = EventReservedValueMask.SuppressEvent;

In the next version I'll probably introduce a new property like SuppressEvent or something like that so it'll be more clear.

Bear in mind that suppressing events only works on Windows and macOS - it doesn't work on Linux. Also, it must be done in a synchronous event handler, so you need to use SimpleGlobalHook instead of TaskPoolGlobalHook. If you want to know why then you can read more here.

FYI, in version 4.0.0 the way to suppress events became a little more clear - HookEventArgs now contains the SuppressEvent property instead of Reserved. You can now do this to suppress events:

e.SuppressEvent = true;
