Is it possible to use Windows Raw Input API without a window (ie from a console application)?

问题

I've tried using RegisterRawInputDevices but my message loops doesn't seem to get any events from GetMessage and hence just 'hangs' there.

回答1:

Do you mean RegisterRawInputDevices?

Since the RAWINPUTDEVICE structure requires you to specify an HWND to receive the WM_INPUT messages, no it's not possible to do this without a window.

Console applications can create windows, and the window probably can receive WM_INPUT while hidden, but you do need a window.

That way I did it (not sure it is the most comfortable way...):

I have started a thread (for the task of filling my input buffer). In this thread I have created a message-only window (its hidden, and can get input datas) with an appropriate window-class.

Then registered the raw input devices.

This thread has its own message handler loop. In the WindowProc of the window-class I've handled the inputs.

(For buffer, You can use boost:circular_buffer, it ROCKS! :D)

In this solution You did need have a window, but it looks like You don't. :)

I hope this can help.
