Hello everyone,
Please help me to answer the following question: I have a software that
needs a second mouse to do some tasks. I intend to connect the mouse to an
USB port and then use it only in that application. But the problem is that
once connected the second mouse behaves just like the first mouse. And the
question is: how can I communicate with the second USB mouse from the
application? I need to do it in a possibly simple way, without developing a
device driver for that purpose - is that possible?
Best regards and thanks for any help,
Rafal Gwizdala
No. You need a filter driver for this.

You may be able to use DirectInput to enumerate the specific device you
want, call SetCooperativeLevel to DISCL_EXCLUSIVE, and Acquire() the
device. At least the documentation says so (and I vaguely remember doing
this at one point ;-).
There some question as to whether you can get background exclusive
access to the device (i.e. I can’t quite tell whether it’s actually
prevented or just discouraged :-), but you should be able to grab it at
least when your app has the focus. I’m too lazy to write a test app to
find out, I’m afraid.
Remember, though, that there’s only 1 pointer in the system. You’ll have
to interpret all the data from the mouse entirely on your own, draw your
own pointer (if desired), etc., etc., etc.

That is an interesting topic (to me at least) so if someone does such a test
app, please let us know how reliable the technique is

Hello again.
Thanks for all the hints. I think I’ll be doing some research on the topic
in few weeks, so when I develop the test app I’ll make it available for
you.
Best regards,

Just to clarify: I am not asking for the code, I only want to know whether
or not the DirectInput “capture” technique is effective.
