How I get the Header HDC of listview in custom draw?

[JoneLe86]

I want to customize the header of a listview, so in NM_CUSTOMDARW i have

Test = (LPNMLVCCUSTOMDARW)Lp <nmcd.hdc)

which for the listview without the header, i tried using

Test = (LPNMCUSTOMDARW)Lp <
and then

Test->hdr.hwndFrom

so

if(Test->hdr.hwndFrom == listview_getheader(LIST))

but it does not work, the listview_getheader(LIST) gives the right hwnd, but how about Test->hdr.hwndFrom, it seems i missed something...

What is Test and what is its value, and that of lp, after this statement?

Use the best guess

The header control is a child window of a list. If you want to customize the header, you must use owner drawing for the header itself. When using MFC, derive a CHeaderCtrl class and implement the virtual DrawItem() handler. To connect this header control class to your list, use subclassing. To enable owner drawing of header items, set the HDF_OWNERDRAW flag for the header items. See Deriving a Custom CHeaderCtrl in the Using the Header Control[^] article. This example contains complete implementation code including the DrawItem() function: http://www.codeguru.com/cpp/controls/listview/sorting/article.php/c977/Indicating-sort-order-in-header-control.htm[^].

hmm I wonder why Everything need to be subclassed, thanks for this information it did help....

LPNMCUSTOMDARW Test = (LPNMCUSTOMDARW)lp I was in the wrong way, Jochen Arndt explained that I should subclass the header first... Thanks
