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.
