ListView (OCX) columns are resizable by default. Hover the mouse pointer over the the column borders, left click and resize/

I don't know about using label objects, with ListView (OCX) - that is a function of the columnheader collection object. Headers may be added through the builder or coded, ex:

procedure AddListViewHeadings(oLV) && oLV = Myform.MyocxListView
with oLV
.COLUMNHEADERS.ADD(,[MANF_CODE],[Code],72,,) && Define column 1 header
.COLUMNHEADERS.ADD(,[MANF_NAME],[Description],152,,) && Define column 2 header
endwith &&oLV
