c# - Can't write to process's input -



i'm trying make c# function make database dump mysql server. , may know, mysql asks password this: enter image description here

so here's did:

public static bool backupdatabase(string filename) {     try     {         string mysqldumpdir = @"c:\program files\mysql\mysql server 5.7\bin\mysqldump.exe";         string user = "root";         string password = "root";         string databases= "hrsmarttest7";         processstartinfo startinfo = new processstartinfo         {             filename = mysqldumpdir,             redirectstandardinput = true,             arguments = string.format("--user {0} --password --databases {1} --result-file=\"{2}\"", user, databases, filename),             useshellexecute = false,             createnowindow = true         };         var mysqldump = new process { startinfo = startinfo, enableraisingevents = true };         mysqldump.start();         system.threading.thread.sleep(3000);         mysqldump.standardinput.autoflush = true;         mysqldump.standardinput.write(password+"\n"); // doesn't job !!!         mysqldump.waitforexit();         mysqldump.close();         return true;     }     catch (exception e)     {         //recordexception(e);         return false;     } }

when execute function, process starts , waits user write password mysqldump.standardinput.write doesn't write , have kill process end program.

please help.

you can add .my.cnf file

[mysqldump] user=root password=root

it safer passing password on command line and/or storing in source code. however, file client's machine should create read-only user backing databases rather using root. backup user needs following permissions:

grant lock tables, select on *.* 'backupuser'@'%' identified 'password';

see blog benjamin cane further details:

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
