.data
PathName db"F:\",0
VolumeName db 16 dup(?)
nameSize dd 50
volumeSerial dd 0
result db 50 dup(?)
.data?


.code
start:
invoke GetVolumeInformation,addr PathName,addr VolumeName,addr nameSize,addr volumeSerial,NULL,NULL,NULL,NULL
invoke wsprintf,addr result,addr VolumeName,addr volumeSerial

invoke MessageBox,NULL,addr result,0,0
invoke ExitProcess,NULL
end start


In this code
i get volume name of usb drive but no serial number

what is my mistake in this code ?

There is a full example here:
