The GlobalMemoryStatus API function returns detailed information about the current load on the physical and virtual memory. You can use the following code to display the current amount of free memory:

Dim ms As MEMORYSTATUS
  Dim msg As String

  ' query for memory data
  ms.dwLength = Len(ms)
  GlobalMemoryStatus ms
  ' create a result message.
  msg = "Total physical memory = " & GetKbytes(ms.dwTotalPhys) & vbCrLf & _
    "Available physical memory = " & GetKbytes(ms.dwAvailPhys) & vbCrLf & _
    "Memory Load = " & ms.dwMemoryLoad & "%" & vbCrLf & _
    "Total Page file = " & GetKbytes(ms.dwTotalPageFile) & vbCrLf & _
    "Available Page file = " & GetKbytes(ms.dwAvailPageFile) & vbCrLf & _
    "Total Virtual memory = " & GetKbytes(ms.dwTotalVirtual) & vbCrLf & _
    "Available Virtual memory = " & GetKbytes(ms.dwAvailVirtual)
  MsgBox msg, vbInformation, "Memory information"

The GetKbytes function is a simple routine that converts a number of bytes into Kbytes, and adds thousand separators:
' Format a memory amoung as a Kbyte or Megabyte

Function GetKbytes(ByVal amount As Long) As String
  ' convert to Kbytes
  amount = amount \ 1024
  GetKbytes = Format(amount, "###,###,###K")
End Function
