How do u distinguish what is what in the API viewer. For ex.


Public Declare Function GetFileTime Lib "kernel32" Alias "GetFileTime" (ByVal hFile As Long, lpCreationTime As FILETIME, lpLastAccessTime As FILETIME, lpLastWriteTime As FILETIME) As Long

Public Type FILETIME
dwLowDateTime As Long
dwHighDateTime As Long
End Type

if i wanna use that function, how would i know what hFile would have to equal to?
OR what to set dwLowDateTime and dwHighDateTime to?
Is there some kind of rules u must follow?

Sorry i always used other API code, never figured it out on my own.
