You can't use Handles unless there is a field IN THE SAME TYPE declared WithEvents, which is obviously not an option for an event of a module or Shared event of a class. You have no choice but to use an AddHandler statement. Where you put it is up to you but, in a regular class, you'd probably do it in a parameterless constructor:

Unless buffering has been disabled in the open call by setting the buffering parameter to 0, the file stream will be either fully buffered or line buffered. This depends on the type of file being opened and on the open mode, but binary file streams are never set to line buffered mode.

In buffered mode, the write method will write to the buffer, but the buffer contents will not be written to the underlying file until either the buffer is full, or a newline is written in line buffered mode.

The flush and close methods will write the buffer contents to the underlying file. The close method also closes the file afterwards.

In OP's code, adding file_stream.flush() to the end of the send function will write the buffer contents through to the underlying file every time the send function is called. An alternative is to add filestream.flush() to the end the send_mouse_click_event function so that the data written by the three calls to send is flushed to the underlying file in one go.

Interesting scenario you're having here @thowimmer. My first hunch would be to say "use the SubscribingEventProcessor instead". However, you pointed out that that's not an option in your setup. I'd argue it's very valuable for others who're in the same scenario to know why that's not an option. So, maybe you can elaborate on that (to be honest, I am curious about that too).

Now for your problem case to ensure events are only handled within the same JVM. Adding the origin to the events is definitely a step you can take, as this allows for a logical way to filter. "Does this event originate from my.origin()?" If not, you'd just ignore the event and be done with it, simple as that. There is another way to achieve this though, to which I'll come to in a bit.

The place to filter is however what you're looking for mostly I think. But first, I'd like to specify why you need to filter in the first place. As you've noticed, the TrackingEventProcessor (TEP) streams events from a so called StreamableMessageSource. The EventStore is an implementation of such a StreamableMessageSource. As you are storing all events in the same store, well, it'll just stream everything to your TEPs. As your events are part of a single Event Stream, you are required to filter them at some stage. Using a MessageHandlerInterceptor would work, you could even go and write a HandlerEnhacnerDefinition allowing you to add additional behaviour to your Event Handling functions. However you put it though, with the current setup, filtering needs to be done somewhere. The MessageHandlerInterceptor is arguably the simplest place to do this at.

However, there is a different way of dealing with this. Why not segregate your Event Store, into two distinct instances for both applications? Apparently they do not have the need to read from one another, so why share the same Event Store at all? Without knowing further background of your domain, I'd guess you are essentially dealing with applications residing in distinct bounded contexts. Very shortly put, there is zero interest to share everything with both applications/contexts, you just share specifics portions of your domain language very consciously with one another.

Note that support for multiple contexts, using a single communication hub in the middle, is exactly what Axon Server can achieve for you. I am not here to say you cant configure this yourself though, I have done this in the past. But leaving that work to somebody or something else, freeing you from the need to configure infrastructure, that would be a massive timesaver.

Hope this helps you set the context a little of my thoughts on the matter @thowimmer.

The problem is that an index signature must include all possible types that the values may have:

You have to add the generic before the =:

You can call GetAsyncKeyState, and check the bit 0x8000 in the return value:

You can get the start and end indices for the groups.

I managed to find the source code for the evtest utility that I mentioned and was able to find the max X and Y values of the touchscreen by using the following code snippet:
