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:
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, I've tried the below as well:
...code here
case WM_NOTIFY:
switch(((LPNMHDR)lParam)->code)
case LVN_COLUMNCLICK:
MessageBox(NULL, "CLICK DETECTED", NULL, MB_OK);
return 0;
...code here
