I'm not sure if I'm messing up, or really what's going on at all. I keep g

      • Hi all~ Was wondering if there is another way (say Win32 method) to access the View type of a CListCtrl just like the way GetView and LVM_GETVIEW do it.. Reason being, the usage of GetView need to have the macro _WIN32_WINNT set to 0x0501, which is what I do not wish to do.. Thanks in advance~
