c++ - MFC - UpdateData(False) + Thread + Debug assertion failed -

-

im using visual studio 2010, work mfc 2008/2010. have problem thread , updatedata(false) init function 

bool cbkav_btap2_appdlg::oninitdialog(){      ....      afxbeginthread (mythreadproc,(lpvoid)getsafehwnd());      return true;  // return true  unless set focus control  }

this thread

uint __cdecl mythreadproc( lpvoid pparam ) {     dword totalphys;     dword availablephys;     dword memoload;     cbt2class* pobject = (cbt2class*)pparam;     pobject->getramandcpuinfo(totalphys,availablephys,memoload  );     cbkav_btap2_appdlg dlgobject;     dlgobject.ec_totalphys = totalphys;      dlgobject.updatedata(false);<--- can not update data     return 0;    }

cbt2class class in dll file created before. ec_totalphys edit_control. when run, return "debud assertion failed". dont know why. please me. thankss. p/s: think need use sendmessage update data dialog search every still can't work.

you passing hwnd thread parameter. not pointer , should not cast anything. can use hwnd post custom message dialog. custom message can include data in wparam , lparam. message handler in dialog runs in main thread , can updatedata call. see example here posting custom message dialog: http://vcfaq.mvps.org/mfc/12.htm

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
