By default a combobox does not have horizontal scroll
bar when text contained in it is longer than the width
of the combobox. I( have researched and found that the send message api
function passing the constant
CB_SETHORIZONTALEXTEND is suposed to insert a scroll bar if the length of the longest string is longer than the width of the combobox. I doesnt seem to work. Does anybody have any information on how to set a horizontal scrollbar for a combobox.
