Hello All, I'm having difficulty detecting the 'LVN_COLUMNCLICK' message from a ListView control. I am entering the WM_NOTIFY for sure, but I can't trap the LVN_COLUMNCLICK. Not sure where else to look, my code seems to follow what is listed on MSDN and just about every snippet I've found. Any ideas would be great!
See Below:
Code:
LPNMHDR nmHdr = NULL;
...code here
        //WM_NOTIFY is very first case, ensures lParam integrity
        switch(message){
	case WM_NOTIFY:
                nmHdr = (LPNMHDR) lParam;
		switch (nmHdr->code){
			case LVN_COLUMNCLICK:
				MessageBox(NULL, "CLICK DETECTED", NULL, MB_OK);
				break;
...code here
Also have tried this:
Code:
...code here
case WM_NOTIFY:
            switch(((LPNMHDR)lParam)->code)
                  case LVN_COLUMNCLICK:
                        MessageBox(NULL, "CLICK DETECTED", NULL, MB_OK);
            return 0;
...code here
