Where do you get the windows constant values from ?

On all the userlibs,.. or most, windows constant values are used like $1001, $1002 etc.

Where are you getting these values from?

On the msdn site all that is displayed, are the names of these values, not the value.

Thanks very much :D

If you look up a function on MSDN, you'll see at the bottom where it tells you the header information, e.g.

I just look them up in the particular .h file... of course you need to already have some visual studio product installed to make it easy, but sometimes you can google the name of the function + the header and someone will have it posted on their site.

Also, there was something in the code archives which included a bunch of the WinAPI constants.

You *may* also find something at allapi.net.

I managed to find a web page that had the main header files :)

If anyone's interested, here's an online search for the windows constants that I put together (along with the list that halo posted), you can find it here. Let me know if you find it useful.
