Pablo,

Does this work for you?

? 0xFFFFFFFF80624EC8 && hex conversion of -2141040952 by the Windows calculator

Are you sure you have that much memory?

>When I needed to convert a negative value into hexadecimal to use it in a WinAPI function I used this routine based in a clever conversion function by Ed Rauh. It works like a charm in Windows 98, but in Windows XP I only get a "Declare DLL caused an exception" error. Anybody kwnows how to make this routine works in WinXP o has an alternative method?
