Hi NG,

i want for my drag and drop treeview control the style TVS_TRACKSELECT
(for example the IE 6 uses this; go to favorites sidebar and drag/drop a
bookmark...): the bold horizontal line between the nodes...

I tried this:

--------------------------------------------------------------------------------
private int TVS_TRACKSELECT = 0x200;
private int GWL_STYLE=-16;
        [DllImport("user32.dll")] private extern static IntPtr
SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
        [DllImport("user32.dll")] private extern static int
GetWindowLong(IntPtr hWnd, int nIndex);

            int style = GetWindowLong(m_SchemaTreeView.Handle,GWL_STYLE);
            SetWindowLong(m_SchemaTreeView.Handle,GWL_STYLE, style |
TVS_TRACKSELECT);
--------------------------------------------------------------------------------

But it does not appear in my treeview. How can I get this style the
right way?

Thanks, Roland!
