Question:
How can I tell in code if my application is running on Windows
NT?
Answer:
The following example demonstrates how to detect if your
application is running under Windows NT. Note that the code will
compile under both 16 and 32 bit platforms.
Example:
{$IFNDEF WIN32}
const WF_WINNT = $4000;
{$ENDIF}
function IsNT : bool;
{$IFDEF WIN32}
var
osv : TOSVERSIONINFO;
{$ENDIF}
begin
result := true;
{$IFDEF WIN32}
GetVersionEx(osv);
if osv.dwPlatformId = VER_PLATFORM_WIN32_NT then exit;
{$ELSE}
if ((GetWinFlags and WF_WINNT) = WF_WINNT ) then exit;
{$ENDIF}
result := false;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
if IsNt then
ShowMessage('Running on NT')
else
ShowMessage('Not Running on NT');
end;
