I'm writing a small programme for Win 98 using VC++ 6, all it is meant to do is start when Windows starts, logging the time & date, then wait until shutdown to log the time & date again. I've got it to do the first bit easily enough, but I'm not sure how to get it to wait for shutdown. Presumably I must put it into a loop waiting to receive WM_ENDSESSION or something, so I need to know it if I can receive / handle messsages if my programme doesn't have a window. Will I need to create an invisible window just so I can get messages?

I do believe that a windowless program also recieves messages. And you will recieve the WM_QUERYENDSESSION message.

Any idea how to get & process them (preferably without MFC)?

Yes, write a Win32 program. Also you may want to look at Petzold's Programming Windows 5th edition at your local book store if you don't want to buy it. Also I'm sure there are online tutorials to get that taken care of. If you want I can supply you with a skeleton program that you can "fill in the blanks".

I know how to process messages for programmes with a window, I need to know how to do it without a window. GetMessage and PeekMessage both require an hWnd, and I've tried supplying it with NULL but nothing seems to work. I can't seem to find much online or in the official docs about windowless message handling (or in my book for that matter). Whatever you know about it would be much appreciated!

You could create a window like normal and do not call ShowWindow().
