CListCtrl Advanced Grid Line Draw

I am developing an application using MFC 4.2.

The LVS_EX_GRIDLINES style is not supported on this version of MFC so I need
to subclass the CListCtrl class and draw it myself.

What become problem is that I must draw the grid lines based on the item
grouping like this:

Thank you very much.

That define should be in the 6.0 Windows SDK in the CommCtrl.h file.

That define should be in the 6.0 Windows SDK in the CommCtrl.h file.  You
should be able to use it.  I have not used VC6 for a long time so I could be
off, but I think you can use them.  The define looks like:


I think this is more dependent on the version of the common controls
installed (like with Internet Explorer 4+) than it is the version of MFC.  I
think the CListCtrl implementation for MFC 4.2 may not have had
SetExtendedStyle(), but it may be easy to add your own by just deriving from
the CListCtrl and adding a new function that sends the message to the
control to set the extended styles.

If you are using VC6 and you want to use the new features of list-controls
available in Windows XP (like grouping), I think that you may want to
download the latest Platform SDK available for that IDE, i.e. the Windows
Server 2003 PSDK (February 2003):
