Windows path doesn't contain C:\WINDOWS\system32, can I add it using batch script? -

-

i writing batch script that, quite reasonably, depends on "c:\windows\system32" being part of path environment variable. encountered (developer's) machine had weird path didn't include system32, , therefore batch script didn't work.

i looked ways batch script check path variable , add system32 if not there. however, solution found used setx ironically enough depends on system32 in path variable. there programmatic ways add system32 path without being there?

also please let me know if such edge case doesn't make sense make script robust against it. i'm not expecting of typical users have such borked path variable. should bother?

try this:

for /f "delims=" %%a in ("%comspec%") set "path=%path%;%%~dpa"

or this:

for /f "delims=" %%a in ("%comspec%") set "compath=%%~dpa" set "path=%path%;%compath:~0,-1%"

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
