It will give you the whole environment in the form of a string list. then , you can access it as usual env:=tenvironment.create; a:=env.values['PATH]; env.free; etc etc look up the values property of tstrings for more info. -------------------------- cut here unit uenv; Interface uses windows,classes; type tenvironment=class(tstringlist) constructor create; end; implementation constructor tenvironment.create; var base,p:pchar; a:string; begin inherited create; base:=GetEnvironmentStrings; <--- for 16-bits, change to GetDosEnvironment. if base=nil then exit; p:=base; while p^#0 do begin a:=p; <-- for 16-bit change this to a:=strpas(p); add(a); p:=p+length(a)+1; end; FreeEnvironmentStrings(base); end;
