how do i check if a pid exists?

can i do what is says on the tin ??? lol

If you have a pid and want to see if the pid is a valid process

Code:

---

Private Declare Function GetPriorityClass Lib "kernel32" (ByVal hProcess As Long) As Long

if GetPriorityClass(hProcess) > 0 then
    ' process exists
else
    ' process does not exist
end if

---

hmmmm


seems to only return a 0 ....

any ideas?
