How to modify mouse coordinates in custom UserControl
I am looking to set up a user control wherein mouse movement input can be refined by a scaling factor. The behaviour would be such that while outside the control, mouse movement is as per normal, but inside the control, any position delta provided by the mouse is say divided by 10 and the cursor progresses much more slowly in the direction, even ideally on a sub-pixel level. It may be that the behaviour is conditional on a key being down.
The solution will need to:
- capture the mouse movement input,
- cancel any normal processing,
- measure the distance in x and y that the mouse reported and that would have normally just been added to the pointer coordinates,
- store a precise new floating point coordinate, then
- ideally hide the pointer,
- redraw the pointer in sub-pixel coordinates, and
- report the approximate integer coordinates back to the operating system so it knows when the pointer might leave the control.
Something I have noticed is that Console.Writeline() seems to interfere with Cursor.Position, suggesting the published cursor value includes text cursor coordinates also. This has been complicating my solutions so far. In general I think I'm interfering too late to be able to influence the mouse the way I would like to and accept the solution may require deeper Windows calls.

You'd need to implement a low level mouse hook. Google for WH_MOUSE_LL...
