This work for 95/98/NT4/2000 (According to the docs :-)):

typedef struct tagPROCESSENTRY32 {

declare integer Process32Next in kernel32 integer hSnapShot, string @PROCESSENTRY32


I have used this in C/C++ but not in VFP but I don't think there's a problem. These API calls are from the tool help functions if you want to have a look at the other things you can do ie: enumerate threads/heap/modules.
