Detect Windows

Try to play with this code (create new project and add this code into Form1):

private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (byref lpVersionInformation as OSVERSIONINFO) as Long

private Type OSVERSIONINFO
dwOSVersionInfoSize as Long
dwMajorVersion as Long
dwMinorVersion as Long
dwBuildNumber as Long
dwPlatformId as Long
szCSDVersion as string * 128 ' Maintenance string for PSS usage
End Type

private Const VER_PLATFORM_WIN32_NT = 2
private Const VER_PLATFORM_WIN32_WINDOWS = 1
private Const VER_PLATFORM_WIN32s = 0

private sub Form_Load()
dim sVer as OSVERSIONINFO ' version structure
sVer.dwOSVersionInfoSize = len(sVer) ' size of structure

' get it
if (GetVersionEx(sVer) = 0) then
' error - do error parsing if needed
msgbox "error In Retrieving Version Info"
else
' got it - parse the platform ID
select case (sVer.dwPlatformId)
case VER_PLATFORM_WIN32_NT:
' check for WinNT/2000
if (sVer.dwMajorVersion <= 4) then
msgbox "Platform: WinNT"
elseif (sVer.dwMajorVersion = 5) then
msgbox "Platform: Win2000"
else
msgbox "Platform: Future Platform???"
end if
case VER_PLATFORM_WIN32_WINDOWS:
' check for win98/95
if ((sVer.dwMajorVersion > 4) or ((sVer.dwMajorVersion == 4) and (sVer.dwMinorVersion > 0))) then
msgbox "Platform: Win98"
else
msgbox "Platform: Win95"
end if
case VER_PLATFORM_WIN32s:
msgbox "Platform: Win32"
end select
end if
end sub

Have fun,
