PRWIN9012020: Problem Adding Horizontal Scroll Bar to List Box ID Number: Q64502

3.00 WINDOWS buglist3.00 fixlist3.10

Summary:

PROBLEM ID: WIN9012020

SYMPTOMS After a list box has been created, an LB_SETHORIZONTALEXTENT message will not cause a horizontal scroll bar to be added to or removed from the list box.

RESOLUTION Microsoft has confirmed this to be a problem in Windows version 3.0. If the scroll bar will be required at any time, set a large scroll range with the LB_SETHORIZONTALEXTENT message at the time of initialization. The scroll bar can be disabled by sending another message with a small scroll range.

This problem was corrected in Windows version 3.1.
