System memory available?

Does anyone know how to get information on how much memory is available on the system? Both RAM and Swap? I have swept through the winapi32.txt file to find anything, but I couldn't find anything that looked like the function i need.

I just need to know how i through a VB code can get the information.

Thanks

Private Type MEMORYSTATUS
    dwLength As Long
    dwMemoryLoad As Long
    dwTotalPhys As Long
    dwAvailPhys As Long
    dwTotalPageFile As Long
    dwAvailPageFile As Long
    dwTotalVirtual As Long
    dwAvailVirtual As Long
End Type
Private Declare Sub GlobalMemoryStatus Lib "kernel32" (lpBuffer As MEMORYSTATUS)
Private Sub Form_Load()
Dim MemStat As MEMORYSTATUS
    'retrieve the memory status
    GlobalMemoryStatus MemStat
    MsgBox "You have" + Str$(MemStat.dwTotalPhys / 1024) + " Kb total memory and" + Str$(MemStat.dwAvailPageFile / 1024) + " Kb available PageFile memory."
End Sub
