Is there any way to detect rawinput (real physical keystrokes) and ignore SendINput

I am looking for way/script in C to detect real physical keystroke. I don't want to use SendInput (or any other simulator input).

If possible, it would be good only to have RAWINPUT data without SendInput.

SendInput generates key events and does not react on real keys. So you may clarify your question.

The usual method to react to key events is handling the WM_KEYDOWN and WM_KEYUP messages. But these will include events generated by SendInput. Do you want a method to detect real key presses and not those simulated ones?

Yes. I just need to detect real ones not simulated ones.

You can still handle the WM_KEY* messages in PreTranslateMessage (see Karsten's solution) because simulated key strokes will be only present if send by your application and might be detected therefore.

SendInput has nothing to do with detection, it sends... :-)
Per application of system-wide?

The normal way is to overwrite PreTranslateMessage and check for these values.

In this webpage from Microsoft is another approach well explained and also some sample code can be found.

Tip: If you handle the keystroke make a return and not handling to the default .

Does WM_KEYDOWN or WM_SYSKEYDOWN have anything to do with SendInput? Can that be generated by SendInput API?

Raw Input inspects packages that are enqueued into the hardware input buffer, long before the system converts them into regular Windows messages. If you want to respond to raw input messages (WM_INPUT) and filter out fake input generated from a call to SendInput you cannot do this in your regular keyboard/mouse message handling. This has to take place when handling WM_INPUT messages.
