Thread: WM_NOTIFY message

How can I extract the NMHDR information from the lParam in the
the WM_NOTIFY message?

I have a WM_NOTFIY case statement in my window procedure and
need to also monitor what notification message is sent. I'm having
one hell of a time trying to figure out how to copy the lParam into
a NMHDR structure.

Any suggestions are greatly appreciated.

Thanks in advance.

Code:

//globally declared
NMHDR *pnmhdr;
//these 3 just as an exmaple
HWND hwndNotifyTest;
unsigned int uiNotifyTestFromID;
unsigned int uiNotifyTestCode;

//in your message handler
case WM_NOTIFY:
{
   //point your header to the lparam (casted as an LPNMHDR)
   pnmhdr=(LPNMHDR)lparam;
   
   //assign the NMHDR's values to the example vars
   hwndNotifyTest=pnmhdr->hwndFrom;
   uiNotifyTestFromID=pnmhdr->idFrom;
   uiNotifyTestCode=pnmhdr->code;
}break;

Thanks to you jdinger. Exactly what I needed to know.
