+ | begin | ||
+ | if not RegQueryStringValue(HKEY_LOCAL_MACHINE, | ||
+ | ' | ||
+ | ' | ||
+ | then begin | ||
+ | Result := True; | ||
+ | exit; | ||
+ | end; | ||
+ | // look for the path with leading and trailing semicolon | ||
+ | // Pos() returns 0 if not found | ||
+ | Result := Pos(';' | ||
+ | end; | ||
+ | </ | ||

+ | if not RegQueryStringValue(HKEY_CURRENT_USER, | ||

+ | // Pos() returns 0 if not found | ||
+ | Result := Pos(';' | ||
