    CListView Problem

    Hi All

    i have a SDI application with a CListView in report style

    If i have a lot of items in my listview, say 1000+ when scrolling down through the list, by clicking on the down arrow on the VScroll

    sometimes the lines and the text become distorted, i have noticed this sometimes

    when there is a lot of items in a listcontrol as well

    Has anyone any ideas on how to overcome this

    Thanks

    Simon

    Do you have gridlines enabled in your listcontrol?
    Are you running on XP?

    Then I also guess that you have "smooth scrolling" enabled in XP. See section 4 "Solving the XP gridlines problem" in http://www.codeproject.com/tips/BoxOTricks.asp
