How can I get an automatic scroll bar on a CEdit Control

I have a CEdit control in my application.  I want it to use
a vertical scroll bar only if necessary.  I was able to find
resources to turn the scroll bar on or off, but this was
independent of how much text was displayed.

I succeeded in getting this automatic scroll bar behavior by
using a CRichEditCtrl.  I set the vertical scroll bar on and
left the disable no scroll off.

Using the CRichEditCtrl seems like overkill for my
application.  Can I get this behavior with CEdit?

Yes, you can use myEdit->ModifyStyle(WS_VSCROLL, 0) to turn off the vertical scroll and myEdit->ModifyStyle(0, WS_VSCROLL) to turn it on.

This just turns the scroll bar on or off.  I am looking for something that will automatically turn it on or off depending on how must text is displayed in the control.

Using your suggestion,  I would have to catch an event every time the text was changed and see if the text still fits in the box.
Then I would have to add the scroll bar, if it no longer fit.

Can't this be done automatically, similar to the way the CRichEditCtrl handles this?

Do you have ES_AUTOVSCROLL?

I have tried ES_AUTOVSCROLL both on and off.  It makes no
difference.  The help for this attribute says:

In a multiline control, Auto VScroll automatically scrolls text up one line when the user presses ENTER on the last line. Type: Bool. Default: False.

So this does not solve my problem.
