Hello all. Does anyone know what the name is for message that is sent by windows prior to shutdown or user-logoff. It's not WM_QUERYENDSESSION nor WM_ENDSESSION. This message has value decimal 59 and comes by before these two. I coded Msg.Msg = 59 but would like to use the constant name in stead of hardcoding value 59. I'm using Delphi3. Thanks in advance for any help.

There are

My hat is off to you for making your code more readable. Windows WM_* definitions are mostly clustered together into a single text file. In C/C++ they are located in winuser.h. I don't have a copy of Delphi in front of me at the moment, but you can just do a quick search for the .pas file. Look in your Delphi dir for a file with the text WM_COMPAREITEM or some other message in it. Open the file and search for the number you want (they're in order, and typically in hex). That should work for all your future needs too. Cheers
