Option Compare Database

Type SYSTEM_INFO
wProcessorArchitecture As Integer
wReserved As Integer
dwPageSize As Long
lpMinimumApplicationAddress As Long
lpMaximumApplicationAddress As Long
dwActiveProcessorMask As Long
dwNumberOrfProcessors As Long
dwProcessorType As Long
dwAllocationGranularity As Long
wProcessorLevel As Integer
wProcessorRevision As Integer
End Type

Declare Sub GetNativeSystemInfo Lib "kernel32" (lpSystemInfo As SYSTEM_INFO)
Declare Function GetCurrentProcess Lib "kernel32" () As Long

Public Function Is64BitProcessor() As Boolean
Const PROCESSOR_ARCHITECTURE_AMD64 As Integer = 9
Const PROCESSOR_ARCHITECTURE_IA64 As Integer = 6
Dim si As SYSTEM_INFO
' call the API
GetNativeSystemInfo si
' check the struct
Is64BitProcessor = (si.wProcessorArchitecture = PROCESSOR_ARCHITECTURE_AMD64 _
Or _
si.wProcessorArchitecture = PROCESSOR_ARCHITECTURE_IA64)
End Function
