Word - Auto-scroll in the Word window

Asked By Nomey

Hi all,

Does anyone here know whether it is possible have the Word window auto-scroll (by vba)? I am asking this is because I woule like to keep looking at the same position all the time while typing, so there are always, let us say 10 (or any other number to be set) lines above the cursor automatically.

Cheers,

That's really hard to do. Firstly, you would need the macro to run on every
possible keypress. That alone makes it almost impracticable. You would have
to fire the macro from almost every keyboard combination that was not already
in used. (I do know of another way, but it is really complicated and
involves external programs which monitor the keystokes in the word editing
window and act accordingly. Don't go there.)

Second is that the scrolling controls in Word VBA are not fine enough for the
job. The key property is the VerticalPercentScrolled property. But as you
can see from the Help, it is a value of type Long, in the range 0 to 100.
You cannot assign fractional values. On a long document, that is not nearly
fine enough control for what you want to achieve.

So, I have to say that it cannot be done.

I'd tend towards the same conclusion, but would probably use "really
should not" rather than "cannot."  The problem with monitoring keystrokes
is bad enough to warrant the should not.  A timer would be a complete
disaster, too.  Can you even imagine, if you were trying to mouse
about, and the thing started scrolling on its own?

But for the actual repositioning, were one bull-headed enough to pursue
this, it *might* be possible to tweak the scrollbar properties at a
finer resolution than the object model allows?

Jonathan & Karl, thanks for your savvy comments! My knowledge of vba is far too basic to even atttempt building such a routine. I thought it to be fairly straightforward, but apparently it is not.

Kind regards,
Shirley
