visual studio 2010 - C++ CreateProcess() function cannot run. Error The memory could not be written -


this question has answer here:

i'm using windows 8 x64 enterprise, vs2010.

i've problem on createprocess().

i've create win32 console project execute _backround_manipulator.exe, application.

implementation here.

#include "stdafx.h" #include <windows.h> #include <tchar.h> #include <stdio.h>  dword runmanipulator(tchar* tszprocesspath);  int _tmain(int argc, _tchar* argv[]) {     _tprintf(_t("---manipulator start...---\n"));     if(0x08 == runmanipulator(_t("_background_manipulator.exe")))         _tprintf(_t("---manipulator started.---\n"));     else         _tprintf(_t("---manipulator cannot run.---\n"));     return 0; }  dword runmanipulator(tchar* tszprocesspath) {     startupinfo _v_startupinfo;     process_information _v_processinfo;     zeromemory(&_v_startupinfo, sizeof(startupinfo));     zeromemory(&_v_processinfo, sizeof(process_information));      _v_startupinfo.cb = sizeof(startupinfo);      if (!createprocess(null, tszprocesspath, null, null, false, 0, null, null, &_v_startupinfo, &_v_processinfo));     {         return 0x12;     }      return 0x08; }

but cannot pass createprocess(null, tszprocespath, /*...*/) function on debug mode.

error this;

enter image description here

what's wrong on code? because created console project?

i appreciate help.

if definition of createprocess

bool winapi createprocess(   _in_opt_    lpctstr               lpapplicationname,   _inout_opt_ lptstr                lpcommandline,   ...

we can note lpcommandline defined in-out parameter , defined not const pointer ( compare lpapplicationname const pointer lpctstr)

and :

the unicode version of function, createprocessw, can modify contents of string. therefore, parameter cannot pointer read-only memory (such const variable or literal string). if parameter constant string, function may cause access violation.

but pass literal string _t("_background_manipulator.exe") lpcommandline. , got excepted result - memory not written
