    ScrollBar in TextBox

    I have TextBox wich displays several lines of text. Its height is enough to display 4 lines only. In case there are more than 4 lines I would like to add ScrollBar to the TextBox automatically. How can I do it?
    Thank you
    Vlad

    Set its Scrollbars Property to 2(vertical).

    Thank you, but I do not want to have it always. I need the scrollbar only if displayed text doesn't fit the text box.

    In that case, your simplest option is to use a richtextbox instead... it'll put them on for you, otherwise you have to use the Sendmessage API to add and remove the scrollbars...

    Determine how many lines in the text box and if more than 4 display scroll bar.
    To count lines in the textbox

    Private Declare Function SendMessage Lib "user32" Alias _
    "SendMessageA" _
    (ByVal hwnd As Long, _
    ByVal wMsg As Long, _
    ByVal wParam As Long, _
    lParam As Any) As Long

    Const EM_GETLINECOUNT = &HBA



    'Call API to determine how many lines of text are in text box
    LinesOfText = SendMessage(Text1.hwnd, EM_GETLINECOUNT, 0&, 0&)


    and now you can
    if LineOfText>4 then
    Text1.ScrollBars = 2'vertical
    else
    Text1.ScrollBars = 0'none
    end if
