>>I´m trying to read the serialnumber from VFP5 but I have come to a stalemate. I´ve tried using the Sys(), the GetVolumeInfo, but unsucessfuly... can someone throw me a line on this?, thanks

>What problems did you have with GetVolumeInformation()? Q139547 in the MSFT KB (see? I can too reference articles that I didn't write. :-) should work for doing this.

In addition, you will need Foxtools.FLL to register the function as I believe VFP 5 didn't allow direct access to the WinAPI. Look for RegFn and CallFn in the Foxtools help. George Tasker also has an extended Foxtools help file here that may help with the syntax.
