    This works.

    'Should dialog be locked to avoid flicker? Would inbound messages be lost if it was locked?
    'Saw this posting by Borje and Lance.
    Code:
    'CALL CtrlRedraw(hWnd, %FALSE) 'Redraw off
    'Do something
    'CALL CtrlRedraw(hWnd, %TRUE) 'Redraw on, plus refresh
    FUNCTION CtrlRedraw( BYVAL hWnd AS LONG, BYVAL rDraw AS LONG) AS LONG
    CALL SendMessage(hWnd, %WM_SETREDRAW, rDraw, 0)
    IF rDraw THEN
    InvalidateRect hWnd, BYVAL %NULL, 0
    UpdateWindow hWnd
    END IF
    END FUNCTION



    Code:
    CASE %WM_SIZE
              'Size listbox to client area at 0,0 or other position using DDT
              IF CBWPARAM <> %SIZE_MINIMIZED THEN   'CBWPARMAM = wParam
                LOCAL ClientX, ClientY, ControlX, ControlY AS LONG
                DIALOG GET CLIENT CBHNDL                TO  ClientX, ClientY                'size of client area
                CONTROL SET LOC CBHNDL, %IDC_LISTBOX1,  0,0                                 'optional
                CONTROL GET LOC CBHNDL,  %IDC_LISTBOX1  TO ControlX, ControlY               'get location of control
                CONTROL SET SIZE CBHNDL, %IDC_LISTBOX1, ClientX-ControlX, ClientY-ControlY  'resize to fit client area
              END IF
              EXIT FUNCTION

    I don't know if PBForms offers some intrinsic feature to do this, but....

    Process WM_SIZE notification in your callback function.

    Use SetWindowPos or MoveWindow to resize and relocate the control.. or with DDT syntax, CONTROL SET LOC and/or CONTROL SET SIZE.

    The PBNote application supplied with the compiler might be a real good example to look at for this. That's SDK-style, but it shows what to do on WM_SIZE.

    Resize listbox to dialog with PbForms

    How would you resize a listbox to match a dialog using PbForms?
    This is a very simple program to view a log file.
Working...
