Use SetTimer and do the autoscrolling a little bit each time you get
WM_TIMER.

Hi folks,

I'm trying to implement an auto-scrolling feature. The user clicks
the mouse and holds down the button in a window, then moves
the point outside of the window and does no release the button.
This is supposed to cause the problem (a la Microsoft Word)
to scroll automatically at a certain speed.

Unfortunately after much experimenting, I cannot find a way
to generate a continuous stream of events (e.g. mouse move)
to implement auto scrolling. My calls to SendInput are basically
being ignored... I tried sending mouse left-button up/down
to see if SendInput works at all, and it does. But move events
are having no effect. I tried setting dx,dy=0 (relative position)
...no effect. I tried nonzero values, same thing.

Can anyone suggest how to create a user-defined event
so that I can get around this obstacle?

Thanks.
