Most recent file in folder... 1

[LiquidBinary]

Can someone paste some code that will allow me to find the most recent file in a directory? i.e. The one file with the most recent creation time. I would like to do this with the raw API and not MFC. I know there are some API calls that can accomplish this, but you all know how big the win32 API is. mlg400@blazemail.com
